Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control transmitter for a switchgear, a remote control receiver for a switchgear, and a remote control system for a switchgear.
Overhead Door The present invention can be applied to a remote control system for remotely controlling an overhead door, a gate, a gate (a gate in a parking lot or the like), a roll screen (for example, a light shielding film), a blind, an awning device, and the like.

[0002]

2. Description of the Related Art Many switchgears have been proposed and widely used in which opening and closing of a switchgear can be instructed using a remote control transmitter. In the case of a remote control transmitter for a switching device, there are few types of instructions for changing the state of the switching device, the frequency of operation is small, and the communicable distance with the remote control receiver is not very long.

For example, a remote control transmitter for a shutter is provided with only three types of operation keys for instructing a shutter opening operation, a closing operation, and a stopping operation of a shutter during opening and closing. It is considered that the frequent operation of the shutter device is the garage shutter device. However, even if the garage shutter device goes out to the vehicle several times a day, the number of operations is ten times a day. It will be below. Further, the communicable distance with the remote control receiver is also selected to be, for example, about 20 m.

As described above, in the case of a remote control transmitter for a shutter, the frequency of operation is small and the communicable distance with the remote control receiver is short, so that a battery having no charging function has been conventionally used.

[0005]

However, the conventional remote control transmitter has the following problems.

Although it is considered that battery exhaustion occurs very rarely, naturally, among many users, some users frequently operate the battery, and such users are liable to exhaust battery. . Also, if the transmission power of the wireless transmission signal is increased, the communicable distance with the remote control receiver is increased, and the remote control receiver can reliably capture the wireless transmission signal. Therefore, in recent years, remote control transmitters with higher transmission power than before have been developed. For example, if the conventional transmission power is expressed as weak power, a remote control transmitter having a transmission power that can be expressed as low power is being developed. In such a remote control transmitter, the possibility of running out of the battery is further increased.

A conventional remote control transmitter has a function of, when an operation key is operated, lighting or blinking an LED corresponding to the operation key, or sounding a buzzer, thereby notifying a user of the reception of the operation. Had. If the battery runs out, even if you operate it, such notification will not be made,
The user can recognize that the battery has run out.

However, in such a case, the battery runs out suddenly from the viewpoint of the user, and the battery cannot be replaced immediately. In the case of a shutter device in which the change of the shutter state can be instructed only by the remote control system, the period during which the change of the shutter state cannot be instructed becomes long, which may be inconvenient. In addition, even if the operation device is located near the shutter other than the remote control transmitter and the shutter device can instruct the change of the shutter state, during the period in which the battery of the remote control transmitter is not exchanged, the user gives an operation instruction one by one. It is inconvenient to go to the place of the department.

It is conceivable to apply a rechargeable battery as the battery of the remote control transmitter, but the problem caused by running out of the battery is the same in this case.

[0010] The above problems also occur in remote control transmitters for opening and closing devices other than shutter devices.

The present invention has been made in consideration of the above points, and minimizes a period during which an instruction to change the state of an opening / closing body cannot be given, and almost always exhibits the convenience of a remote control transmitter. It is an attempt to provide a machine.

Another object of the present invention is to provide a remote control receiver for an opening / closing device which is compatible with such a remote control transmitter for a switching device. Naturally, it also intends to provide a new remote control system.

[0013]

The original transmission signal includes a flag sequence F indicating the head of the original transmission signal, and the remote control transmitter 10 as the transmission source.
Information section I including an identification code ID and information to be transmitted (for example, an opening operation instruction, a closing operation instruction, a stop operation instruction, and the like).
NF.

The control unit 12 of the remote control transmitter 10 repeats the original transmission signal (hereinafter, appropriately called a frame) shown in FIG. 3, for example, while the key 11a, 11b or 11c of the operation unit 11 is operated. This is given to the transmission unit 13. When the operation time of the key 11a, 11b or 11c is short, the minimum number of repetitions (for example, 5 times) is determined in advance, and the original transmission signal shown in FIG. May be given. The control unit 12 of the remote control transmitter 10 includes the remote control transmitter 10
Is pre-installed.

The transmission section 13 modulates such an original transmission signal (frame) to transmit the signal in a radio frequency band (for example, 426 MHz).
Degree) signal (wireless transmission signal) and transmit antenna 1
Radiate from 4 into space. The transmission unit 13 includes a band-pass filter and a power amplifier as necessary. Although the modulation scheme of the original transmission signal is arbitrary, for example, an ASK modulation scheme or an FSK modulation scheme can be applied.

The transmission antenna 14 radiates a radio transmission signal into space as described above. The transmission antenna 14 is provided, for example, inside a housing constituting the remote control transmitter 10.

The notification unit 15 performs a notification operation under the control of the control unit 12 to allow the user to recognize that the instruction signal of the opening operation, the closing operation, or the stop operation from the operation unit 11 has been received. . The notification unit 15 may be, for example, a light-emitting element (omitted in FIG. 2) corresponding to each of the keys 11a, 11b, and 11c described above, and may visually notify by lighting or blinking (such as a liquid crystal display). Visual notification by a character or the like may be used), or a buzzer or a speaker, for example, may be used to give an audible notification. Others may appeal to other human sensations such as vibration. The following description focuses on the case where the notification unit 15 is a buzzer.

The notifying unit 15 also notifies the user when the remaining capacity of the battery 16 that will be described later becomes low under the control of the control unit 12.

In the first embodiment, the notification unit 15
Although both the one for notifying that the instruction signal of the opening operation, the closing operation or the stop operation from the operation unit 11 has been received, and the one for notifying that the remaining available capacity of the battery 16 has decreased, Needless to say, a separate notification unit may be provided.

The battery 16 supplies operation power to each unit of the remote control transmitter 10. In the case of the first embodiment, the battery 16 is intended to be a general battery such as a lithium battery or a mercury battery, in other words, a battery that needs to be replaced when the battery runs out. Is also good. It should be noted that, even when a rechargeable battery (including a solar cell) is applied, the present invention is directed to a device that is charged by a user using a charging device or the like. The following description of the first embodiment is mainly made on the assumption that the battery 16 needs to be replaced when the battery runs out.

The remaining capacity monitoring unit 17 in the first embodiment
Is obtained based on the electrical characteristics of the battery 16 and provides the control unit 12 with information on whether or not the remaining capacity that can be supplied by the battery 16 indicates that the replacement time (battery exhaustion) is about to expire. is there. For example, a comparator circuit that compares the power supply voltage of the battery 16 with a predetermined threshold voltage can be applied. In this case, when the power supply voltage of the battery 16 becomes equal to or lower than the predetermined threshold voltage, it indicates that the replacement time (battery exhaustion) will soon come.

On the other hand, the remote control receiver 20 includes a receiving antenna 21, a receiving unit 22, a control unit 23, an ID memory 24, and the like. Note that the remote control receiver 20 is connected to the shutter drive unit 40.

The receiving antenna 21 is connected to the remote control transmitter 10
It captures the radiated radio waves from and converts it into an electric signal (wireless reception signal). Since the remote control transmitter 10 can take various positions, the receiving antenna 21 is preferably provided in a form protruding outside, for example, in consideration of reception sensitivity. Further, since the remote control transmitter 10 can take various positions as the receiving antenna 21, for example,
An omnidirectional or one having a considerably wide directional range is applied.

The receiving section 22 demodulates the radio reception signal given from the reception antenna 21 to obtain an original transmission signal (demodulation signal) that the remote control transmitter 10 is trying to transmit. The demodulated signal obtained as described above is provided to the control unit 23. The receiving unit 22 includes a band-pass filter that uses a radio frequency band as a pass band, a preamplifier, and a low-pass filter that uses a band of a demodulated signal as a pass band, as necessary.

The control section 23 controls each section of the remote control receiver 20, and is composed of, for example, a microcomputer. Here, in FIG.
Reference numeral 3 describes that not only control related to remote operation but also drive control for the shutter drive unit 40 is performed. Note that a control unit that performs control related to remote operation and a control unit that performs drive control on the shutter drive unit 40 may be provided separately. For example, a control unit that performs drive control on the shutter drive unit 40 may be provided in an external unit of the remote control receiver 20.

When the registration unit (not shown) instructs the remote control receiver 20 to register an identification code (hereinafter, referred to as an ID) of the remote control transmitter 10 that can be instructed, the control unit 23 fetches the ID. Is stored in the ID memory 24.

The control section 23 decodes the demodulated signal from the receiving section 22 and determines that the ID contained in the demodulated signal is an ID.
After confirming whether the remote control transmitter 10 of the transmission source can issue an instruction for the shutter based on whether or not the shutter is registered in the memory 24, the operation content of the designated shutter, that is, the opening of the shutter, In addition to recognizing the operation, the closing operation or the stopping operation, a shutter driving signal for executing the opening operation, the closing operation or the stopping operation of the shutter is formed based on the recognition contents (opening operation, closing operation or stopping operation), and the shutter It is given to the drive unit 30.

As described above, the remote control transmitter 1
0 indicates that the original transmission signal is repeatedly transmitted.
When a predetermined number of demodulated signals (original transmission signals) transmitted by the same remote control transmitter 10 (original transmission signals) are obtained within a predetermined time (may be less than the minimum number of repetitive transmissions), the demodulated signals are The above control is performed as valid.

Further, the control unit 23 determines whether the remote control transmitter 10 of the transmission source cannot issue an instruction for the shutter or if the instruction content from the remote control transmitter 10 is inconsistent with the current shutter state (for example, In the case where an opening operation is instructed in the shutter open state), the contents of the instruction are ignored.

As described above, the ID memory 24 stores the ID of the remote control transmitter 10 (not limited to one) that can issue a valid instruction to the remote control receiver 20. And a nonvolatile memory such as an EEPROM.

The shutter driving section 40 is constituted mainly by a motor for moving the shutter up and down, for example, and operates in accordance with a shutter driving signal from the control section 23 to a desired operation (for the motor). Forward rotation, reverse rotation,
(Rotation stop, etc.) to open, close, and stop the shutter.

(A-2) Operation of Remote Control Transmitter 10 of First Embodiment Hereinafter, the operation of remote control transmitter 10 of the first embodiment will be described.
This will be described with reference to the flowchart of FIG.

The control unit 12 of the remote control transmitter 10 includes an open operation instruction key 11 a and a stop operation instruction key 11 of the operation unit 11.
b, or monitoring operation of the closing operation instruction key 11c (step 100).

When the open operation instruction key 11a, the stop operation instruction key 11b, or the close operation instruction key 11c is operated, the control unit 12 fetches the monitoring result of the remaining capacity monitoring unit 17 and It is determined whether the remaining capacity that can be supplied is sufficient (step 101).

If the remaining capacity is sufficient, the control unit 12
The notification unit 15 causes the notification that the key operation has been received to be executed (step 102). If the remaining capacity is insufficient, the control unit 12 uses the notification unit 15 to indicate that the remaining capacity is insufficient (in other words, the control unit 12). And that the battery 16 is about to run out (step 10).
3). Note that the latter notification also indicates that a key operation has been accepted.

After that, the control unit 12 forms an original transmission signal corresponding to the current operation key, gives it to the transmission unit 13, and causes it to be wirelessly transmitted to the remote control receiver 20 (step 10).
4) Return to the key operation waiting state.

Here, when the notification unit 15 is constituted by a buzzer, the buzzer sound is intentionally made different when the remaining capacity is sufficient and when the remaining capacity is insufficient. Such two types of buzzer sounds may be different in pitch, volume and tone, may be a continuous sound and an intermittent sound, or may be two kinds of intermittent sounds having different intermittent periods, and the like. Alternatively, the sounding time may be different, or a combination of the above characteristics may be used.

When such two types of buzzer sounds are applied, if there is a difference in power consumption, the buzzer sound when the remaining capacity is insufficient depends on the threshold at the time of judgment. May be selected. If a buzzer sound with low power consumption is selected as the buzzer sound when the remaining capacity is insufficient, there is a merit that many key operations can be received even after it is determined that the remaining capacity is insufficient for the first time. On the other hand, when a buzzer sound with high power consumption is selected as the buzzer sound when the remaining capacity is insufficient, the time until the battery runs out after the battery capacity is judged to be insufficient for the first time is determined. It can be shortened, and the time until the battery runs out can be unnecessarily lengthened, thereby preventing the reliability of the need for battery replacement from being reduced.

Although FIG. 4 shows two stages in which the remaining capacity is sufficient or insufficient, it is also possible to subdivide the insufficient stage and issue a different notification at each of the subdivided insufficient stages. good.

Even when a light emitting element is used as the notification unit 15, two types of notification are distinguished as in the case of the buzzer.

In the case of the first embodiment, the operation of the remote control receiver 20 is the same as that of the conventional remote control receiver, and the description of the operation will be omitted.

(A-3) Effects of the First Embodiment As described above, according to the remote control system 1 of the first embodiment, the remote control transmitter 10 monitors the remaining capacity of the internal battery 16 that can be supplied. A function is provided to notify the user when the remaining capacity becomes insufficient, so that the user can prepare for battery replacement before the battery runs out, and can replace it immediately when the battery runs out or before the battery runs out. Can be replaced (if the battery is a rechargeable battery, it can be charged), and the remote control transmitter 10 can be almost always in a state where the shutter can be controlled.

Here, as a configuration for notifying that the remaining capacity has become insufficient, a notifying unit 1 notifying that a key operation has been received.
5, the addition of a configuration for achieving the above advantages can be minimized.

Further, for example, opening, closing,
When there is an operation to change the state of the shutter such as a stop, the user is notified that the remaining capacity is insufficient, so that the user can be made aware of that fact. By the way, the remaining capacity is periodically monitored by a timer, etc.
Although there is a method of notifying that it is insufficient (constituting another embodiment), in this case, even if the notification is made, the user does not carry the remote control transmitter 10 and the user recognizes the fact. In some cases, you cannot.

(B) Second Embodiment Next, a second embodiment in which the remote control transmitter for a switching device, the remote control receiver for a switching device, and the remote control system for a switching device according to the present invention are applied to a remote control system for a shutter. Will be briefly described with reference to the drawings.

Also in the case of the second embodiment, only the remote control transmitter is characterized, and the remote control receiver may be the same as the conventional one.

The remote control transmitter 10A according to the second embodiment
Is the remaining capacity monitoring unit 17 as shown in the block diagram of FIG.
The internal configuration of A is different from that of the remaining capacity monitoring unit 17 of the first embodiment, so that the operation of the control unit 12A is slightly different from that of the first embodiment. Note that FIG. 5 shows portions different from those of the first embodiment, and portions corresponding to those in FIG. 1 described above are denoted by corresponding reference numerals. In the following description, reference numerals in FIG.

The remaining capacity monitoring unit 1 of the first embodiment described above
7 monitors the remaining capacity of the battery 16 that can be supplied based on the electrical characteristics of the battery 16, such as a comparator circuit that compares the power supply voltage of the battery 16 with a predetermined threshold voltage.

The remaining capacity monitoring unit 17A of the second embodiment is
The remaining capacity that can be supplied by the battery 16 is monitored without using the electrical characteristics of the battery 16.
7A is a remaining capacity estimation value counter 3 as shown in FIG.
0, a comparator 31 and a remaining capacity flag holding unit 32.

The remaining capacity estimation value counter 30 is
Under the control of A, a parameter that indirectly defines the remaining capacity that the battery 16 can supply is counted. The remaining capacity estimation value counter 30 counts the number of key operations if the number of repeated transmissions of the original transmission signal at the time of operating the operation keys 11a to 11c is constant regardless of the key operation time. The remaining capacity estimation value counter 30 is operated by the operation key 11.
If the number of times the original transmission signal is repeatedly transmitted during the operations of a to 11c changes depending on the key operation time, the number of transmission frames (the number of transmitted original transmission signals) is counted.

As the number of key operations and the number of transmission frames increase, the amount of power supplied from the battery 16 supplied up to now also increases. On the other hand, the suppliable capacity of the battery 16 before the start of use is almost constant. The number of times and the number of transmission frames indirectly define the remaining capacity. The second embodiment focuses on this point.

The comparator 31 has a remaining capacity estimation value counter 30.
Is compared with a predetermined threshold value internally stored (for example, 65,000 times if the number of key operations), and when the counted value is larger than the threshold value, A flag value indicating that the replacement time of 16 (battery exhaustion) will soon be reached (insufficient remaining capacity) is set in the remaining capacity flag holding unit 32. When the count value is equal to or less than the threshold value, the remaining capacity of the battery 16 is sufficient. Is set in the remaining capacity flag holding unit 32.

As described above, the remaining capacity flag holding unit 32
This holds a flag indicating whether the remaining capacity of the battery 16 is sufficient or insufficient.

As described above, in the case of the second embodiment, the configuration of the remaining capacity monitoring unit 17A is different from that of the first embodiment, but the operation of the control unit 12A is substantially the same as that of the first embodiment. The differences are as follows. In the description of the different points, the flowchart of FIG. 4 used in the first embodiment is referred to.

The control unit 12A is provided with any of the keys 11a to 11a.
When the button 11c is operated, it is determined in step 101 whether the remaining capacity is sufficient or insufficient. In this case, the determination is performed based on the flag held in the remaining capacity flag holding unit 32.

After the notification that the key operation has been accepted or the notification that the remaining capacity is insufficient is performed,
The control unit 12A causes the transmission processing of the original transmission signal to be executed in step 104. At this time, the remaining capacity estimation value counter 3
The process of increasing the count value of 0 is also performed. When the notification that the remaining capacity is insufficient is performed, only the process of transmitting the original transmission signal may be performed, and the process of increasing the count value of the remaining capacity estimation value counter 30 may not be performed.

Further, apart from FIG. 4, the control unit 12A of the second embodiment also performs the following processing. When the battery 16 is replaced and the cold start is performed, the control unit 12A clears the count value of the remaining capacity estimation value counter 30 to 0 as a process at the time of a cold start,
The flag value in the remaining capacity flag holding unit 32 indicates that the remaining capacity of the battery 16 is sufficient. The battery 16
Is a charging type, the control unit 12A performs a hot start by charging, and in the process at the time of the hot start, clears the count value of the remaining capacity estimation value counter 30 to 0, and sets the flag value of the remaining capacity flag holding unit 32. Make the initial settings for.

Although FIG. 5 shows that the remaining capacity monitoring unit 17A is constituted by a digital circuit, the remaining capacity monitoring unit 17A may be realized by software processing in the control unit 12A.

The second embodiment differs from the first embodiment in the configuration of the remaining capacity monitoring unit 17A.
The same effect as the embodiment can be obtained.

As a method of indirectly detecting insufficient battery capacity, the following method may be used in addition to the second embodiment. Insufficiency may be detected by the accumulated time of the transmission time of the transmission frame. For example, open operation, stop operation,
If the transmission frame length changes depending on the type of the closing operation, detection based on the accumulated transmission time is effective. Also, in the case where the content of the instruction is notified to the remote control receiver by changing the frequency or bit rate of the transmission signal by the opening operation, the stopping operation, and the closing operation (that is, in the case of a system without the concept of a frame), The detection based on the accumulated transmission time is effective.

(C) Third Embodiment Next, a third embodiment in which the remote control transmitter for a switching device, the remote control receiver for a switching device, and the remote control system for a switching device according to the present invention are applied to a remote control system for a shutter. Will be briefly described with reference to the drawings.

In the case of the third embodiment as well, only the remote control transmitter has features, and the remote control receiver may be the same as the conventional one.

The configuration of the remote control transmitter according to the third embodiment can also be represented in FIG. 1 described above, but the control operation of the control unit 12 is different from that of the first embodiment. Hereinafter, the third
The control operation of the control unit 12 according to the embodiment will be described with reference to FIG. In FIG. 6, the same steps as those in FIG. 4 are denoted by the same reference numerals.

When any one of the keys 11a to 11c is operated in the key operation standby state, the control unit 12 determines whether or not the remaining capacity that the battery 16 can supply is sufficient (steps 100 and 101). .

If the remaining capacity is sufficient, the control unit 12
After the notification unit 15 performs notification that the key operation has been accepted (step 102), an original transmission signal corresponding to the current operation key is formed and provided to the transmission unit 13 and transmitted to the remote control receiver 20. Radio transmission (step 10
4) Return to the key operation waiting state.

On the other hand, if the remaining capacity is insufficient, control unit 12 determines whether or not the transmission permission flag is set (step 110). The transmission permission flag is
For example, what the control unit 12 stores internally,
In the initial state, it is set.

When the transmission permission flag is set, the control unit 12 causes the notification unit 15 to execute notification that the remaining capacity is insufficient (in other words, that the battery 16 is almost exhausted). (Step 103), the transmission permission flag is reset (Step 111), and thereafter, an original transmission signal corresponding to the current operation key is formed, and the transmission unit 1
3 and wirelessly transmitted to the remote control receiver 20 (step 104), and returns to a key operation waiting state.

On the other hand, if the transmission permission flag is not set, the control section 12 sets the transmission permission flag (step 112), and returns to the key operation waiting state.

After the control section 12 performs the above-described control shown in FIG. 6, after the remaining capacity of the battery 16 becomes insufficient, even if the user operates the key, the operation is performed twice. Once and alternately.

Note that steps 110 to 103
When the process is shifted to, the notification that the key operation has been received may be performed instead of notifying that the remaining capacity is insufficient.

According to the third embodiment, after the remaining capacity of the battery 16 becomes insufficient, even if a key operation is performed, the ratio of accepting the operation is reduced. Indirect notification), the user can indirectly recognize that the remaining capacity is insufficient through the ineffectiveness of the operation keys, and as a result, the same effect as in the first embodiment can be obtained. Can be.

The following are examples of modifications of the third embodiment.

When the remaining capacity is insufficient, the number of stages is set to, for example, two, and while the degree of the remaining capacity is small, only an auditory or visual notification operation is performed. In addition, or instead of this, the ratio of accepting key operations may be reduced.

Further, the operation acceptance ratio is not limited to the ratio of one operation to two operations as in the above-described embodiment, and may be more or less than this, or gradually accepted. The ratio may be reduced, the effect on the operation may be reduced, and the fact that the remaining capacity is insufficient may be indirectly indicated.

(D) Fourth Embodiment Next, a fourth embodiment in which the remote control transmitter for a switching device, the remote control receiver for a switching device, and the remote control system for a switching device according to the present invention are applied to a remote control system for a shutter. Will be briefly described with reference to the drawings.

In the case of the fourth embodiment as well, only the remote control transmitter has features, and the remote control receiver may be the same as the conventional one.

The configuration of the remote control transmitter according to the fourth embodiment can also be represented in FIG. 1 described above, but the control operation of the control unit 12 is different from that of the first embodiment. Further, the second embodiment is different from the first embodiment in that a unit capable of recognizing a shortage of the remaining capacity in two stages is applied as the remaining capacity monitoring unit 17. In the case of the fourth embodiment, the shutter opening operation can be performed by a device other than the remote control transmitter, that is, by the operation unit provided near the shutter.
It is assumed that it can instruct a closing operation and a stopping operation.

Hereinafter, the control operation of the control unit 12 according to the fourth embodiment will be described with reference to FIG. Note that, in FIG. 7, the same and corresponding steps as those in FIG. 4 are denoted by the same reference numerals.

When any of the keys 11a to 11c is operated in the key operation standby state, the control unit 12 determines whether or not the remaining capacity that the battery 16 can supply is sufficient (steps 100 and 101). .

If the remaining capacity is sufficient, the control unit 12
After the notification unit 15 performs notification that the key operation has been accepted (step 102), an original transmission signal corresponding to the current operation key is formed and provided to the transmission unit 13 and transmitted to the remote control receiver 20. Radio transmission (step 10
4) Return to the key operation waiting state.

If the remaining capacity is insufficient, the control unit 12
Determines whether the degree of insufficiency is large (step 120).

If the degree of insufficiency is small even if the remaining capacity is insufficient, the control unit 12 causes the notification unit 15 to execute notification that the remaining capacity is insufficient (step 103). Thereafter, the control unit 12 forms an original transmission signal corresponding to the current operation key, and supplies the original transmission signal to the transmission unit 13.
Wireless transmission to the remote control receiver 20 (step 1
04), the operation returns to the key operation waiting state.

On the other hand, if the remaining capacity is insufficient and the degree of the insufficiency is large, the control unit 12 determines whether the current operation key is the stop operation instruction key 11b (step 121). . Then, the stop operation instruction key 11
If it is b, the process proceeds to step 103, and if it is any other key, it immediately returns to the key operation waiting state.

When the control unit 12 performs the control shown in FIG. 7 as described above, if the remaining capacity of the battery 16 is insufficient and the degree of the insufficiency is large, the user operates the keys by operating the keys. However, the operation key is the instruction key 11 for the stop operation.
Only in the case of b, the operation is accepted and the original transmission signal is transmitted.

According to the fourth embodiment, the same effect as in the first embodiment can be obtained. In addition to this,
Even in a situation where the remaining capacity of the battery 16 is considerably small, the effect of being able to execute a stop operation instruction which is usually considered to be on the safer side than the opening operation or the closing operation can be executed while suppressing waste of the remaining capacity. Play.

In the above description, when the remaining capacity of the battery 16 is insufficient and the degree of the insufficiency is large, only the operation of the stop operation instruction key 11b is accepted. May be changed to the open operation or close operation instruction key 11a or 11c, or the instruction key for restricting reception may be selectable by a dip switch or the like. It may be determined according to the purpose of use of the shutter device. For example, if opening is safer, the opening operation instruction key 11a is used.

(E) Fifth Embodiment Next, a fifth embodiment in which the remote control transmitter for a switching device, the remote control receiver for a switching device, and the remote control system for a switching device according to the present invention are applied to a remote control system for a shutter. Will be briefly described with reference to the drawings.

Here, also in the case of the fifth embodiment, only the remote control transmitter has the feature, and the remote control receiver may be the same as the conventional one. As will be described later, in an embodiment obtained by modifying the fifth embodiment, the remote control receiver may need to be changed.

The configuration of the remote control transmitter according to the fifth embodiment can also be represented in FIG. 1, but the control operation of the control unit 12 is different from that of the first embodiment. Further, the second embodiment is different from the first embodiment in that a power amplifier in the transmission unit 13 that can switch the amplification gain in two stages is applied.

Hereinafter, the control operation of the control unit 12 according to the fifth embodiment will be described with reference to FIG. In FIG. 8, the same steps as those in FIG. 4 and corresponding steps are denoted by the same reference numerals.

When any of the keys 11a to 11c is operated in the key operation standby state, the control unit 12 determines whether or not the remaining capacity that the battery 16 can supply is sufficient (steps 100 and 101). .

If the remaining capacity is sufficient, the control unit 12
After the notification unit 15 performs notification that the key operation has been accepted (step 102), an original transmission signal corresponding to the current operation key is formed and provided to the transmission unit 13 and transmitted to the remote control receiver 20. Radio transmission (step 10
4) Return to the key operation waiting state. At the time of this transmission, the amplification gain of the power amplifier inside the transmission unit 13 is the larger gain (initial setting) of the two-stage amplification gain that the power amplifier can take.

On the other hand, if the remaining capacity is insufficient, the control unit 12 causes the notification unit 15 to perform notification that the remaining capacity is insufficient (step 103), and also sets the amplification gain in the power amplification unit. Is switched to a smaller gain (step 130), and thereafter, an original transmission signal corresponding to the current operation key is formed and given to the transmission unit 13 for wireless transmission to the remote control receiver 20 (step 104). Return to the operation waiting state.

When the remaining capacity of the battery 16 is insufficient due to the control shown in FIG. 8 performed by the control unit 12, the transmission power of the radio signal relating to the original transmission signal is reduced. When the transmission power is reduced in this manner, the distance that the radio wave from the remote control transmitter 10 can reach the remote control receiver 20 (effective range from the viewpoint of the operator) is shortened, so that the operator recognizes that the battery capacity is low. can do.

According to the fifth embodiment, effects similar to those of the first embodiment can be obtained. In addition to this,
When the remaining capacity of the battery 16 is insufficient, the transmission power is reduced, so that the time until the battery runs out can be prolonged, and there is also an effect that a margin can be provided for replacement preparation and the like. .

The following are examples of modifications of the fifth embodiment.

The stage where the remaining capacity is insufficient may be divided into multiple stages, and the smaller the remaining capacity, the smaller the amplification gain of the power amplifier in the transmitting unit 13 may be.

When the insufficient remaining capacity is first detected, for example, the switching of the amplification gain is notified to the remote control receiver 20 (by radio transmission), and the control unit of the remote control receiver 20 receiving this is notified. 23 may increase the amplification gain of the preamplifier in the receiving unit 22. In this case, even if the transmission power from remote control transmitter 10 is reduced, the communicable distance between remote control transmitter 10 and remote control receiver 20 can be made substantially the same as before.

Conversely, when the remaining capacity of the remote control transmitter is insufficient, the amplification gain may be increased. Battery 1
If the remaining capacity that can be supplied to the power supply 6 is insufficient, the operating voltage may decrease and the transmission power may decrease. To avoid this, the amplification gain may be increased when the remaining capacity is insufficient.

(F) Sixth Embodiment Next, a sixth embodiment in which the remote control transmitter for a switching device, the remote control receiver for a switching device, and the remote control system for a switching device according to the present invention are applied to a remote control system for a shutter. Will be briefly described with reference to the drawings.

Here, in the case of the sixth embodiment, both the remote control transmitter and the remote control receiver have characteristics.

The configurations of the remote control transmitter 10 and the remote control receiver 20 according to the sixth embodiment can also be represented by FIG. 1 described above.

However, the controller 12 of the remote control transmitter 10
Is different from the first embodiment. The control operation performed by the control unit 23 of the remote control receiver 20 is also different from the conventional one.

First, the control operation of the control unit 12 of the remote control transmitter 10 according to the sixth embodiment will be described with reference to FIG. In FIG. 9, the same steps as those in FIG. 4 are denoted by the same reference numerals.

When any of the keys 11a to 11c is operated in the key operation standby state, the control unit 12 determines whether or not the remaining capacity that the battery 16 can supply is sufficient (steps 100 and 101). .

If the remaining capacity is sufficient, the control unit 12
After the notifying unit 15 notifies that the key operation has been accepted (step 102), an original transmission signal according to the format shown in FIG. 10 corresponding to the current operation key is formed, and the remaining capacity is sufficient. Is given to the transmitting unit 13 by the standard number of repetitions, and is transmitted wirelessly to the remote control receiver 20 (step 140), and returns to the key operation waiting state.

On the other hand, if the remaining capacity is insufficient, the control unit 12 causes the notifying unit 15 to execute notification that the remaining capacity is insufficient (step 103), and then responds to the current operation key. An original transmission signal according to the format shown in FIG. 10 is formed, and is provided to the transmission unit 13 by the number of repetitions when the remaining capacity is insufficient, and wirelessly transmitted to the remote control receiver 20 (step 141). ), The operation returns to the key operation waiting state.

FIG. 10 shows the format of an original transmission signal according to the sixth embodiment. As is clear from the comparison between FIG. 3 and FIG. 10, the format of the first embodiment is further provided with a repetition number flag RF.

When the original transmission signal is formed in step 140 described above, the repetition number flag RF is set to “standard”.
Indicates, in other words, that the remaining capacity is sufficient,
On the other hand, when the original transmission signal is formed in step 141 described above, the repetition count flag RF indicates "decrease", in other words, indicates that the remaining capacity is insufficient.

When the remaining capacity of the battery 16 is insufficient, the control section 12 performs the above-described control shown in FIG. I do.

For example, when the remaining transmission capacity is sufficient, the number of repetitive transmissions of the original transmission signal is a number corresponding to the period during which the operation key is operated (however, the minimum number (for example, five times) is fixed). For example, the number of repetitive transmissions of the original transmission signal when the remaining capacity is insufficient is fixed to the above-mentioned minimum number or a fixed number less than the minimum number.
For example, if the number of repetitive transmissions of the original transmission signal when the remaining capacity is sufficient is a fixed number (for example, five),
The number of repetitive transmissions of the original transmission signal when the remaining capacity is insufficient is fixed to a smaller fixed number (for example, three times).

Next, a control operation of the control unit 23 of the remote control receiver 20 according to the sixth embodiment will be described with reference to FIG.

The control unit 23 of the remote control receiver 20 waits for the reception of the demodulated signal (original transmission signal) from the reception unit 22 (step 200). Then, when a demodulated signal is given, the contents of the repetition count flag RF in the demodulated signal are determined (step 201). In addition,
The demodulated signal given to the control unit 23 in the standby state is
In most cases, this is the first transmission of whether the remote control transmitter 10 repeatedly transmitted.

The content of the repetition count flag RF is “standard”
If (the remaining capacity is sufficient), the control unit 23 waits for the same number of demodulated signals to be given (including the demodulated signal at the time of affirmative in step 200) for the number of arrivals determined for the standard time (time limit). Exist), and when the demodulated signals of the number arrive, the processing shifts to step 204 (step 202).

On the other hand, if the content of the repetition count flag RF is “decrease” (the remaining capacity is insufficient), the control unit 23
Waits for the same number of demodulated signals to be provided for the number of arrivals determined for the decreasing time (there is a time limit). When the number of demodulated signals arrives, the process proceeds to step 204 ( Step 20
3).

In step 202 or 203, if the number of demodulated signals cannot be received even when the time limit is reached, the control unit 23 returns to the state of waiting for demodulated signals.

Here, for example, if the number of repetitive transmissions in the “standard” state in the remote control transmitter 10 is 5, the number of arrivals in the “standard” state in which the demodulated signal is valid in the remote control receiver 20 is reduced to three. If the number of repetitive transmissions at the time of “decrease” in the remote control transmitter 10 is three, the number of arrivals at the time of “decrease” in which the demodulated signal is valid in the remote control receiver 20 is set to two.

As described above, when a predetermined number of demodulated signals having the same contents arrive, the control unit 23 registers the ID of the remote control transmitter 10 included in the demodulated signal in the ID memory 24. (Step 20)
4).

If not registered, control section 23 returns to a state of waiting for a demodulated signal. On the other hand, if it is registered, the control unit 23 decodes the content of the information part in the demodulated signal, and determines which of the opening operation, the stop operation, and the closing operation is instructed (step 205), and the decoding result The shutter drive unit 40 forms a shutter drive signal according to the
(Step 206), and then returns to a state of waiting for a demodulated signal.

The control unit 23 performs the above-described control shown in FIG. 11 so that the number of arrivals at which the demodulated signal is made valid can be changed in accordance with the change in the number of repetitive transmissions of the original transmission signal on the remote control transmitter 10 side. It can change and process valid demodulated signals.

According to the sixth embodiment, effects similar to those of the first embodiment can be obtained.

In addition, the remote control transmitter 10 reduces the number of times the original transmission signal is repeatedly transmitted when the remaining capacity of the battery 16 is insufficient. This has the effect of extending the time required for the replacement, and allowing time for replacement preparation.

As described above, even if remote control transmitter 10 reduces the number of repetitive transmissions of the original transmission signal, remote control receiver 20 also reduces the number of arrivals of the same demodulated signal that makes the demodulated signal valid. As a result, effective reception processing is hardly reduced.

The following are examples of modifications of the sixth embodiment.

The stage where the remaining capacity is insufficient is divided into multiple stages, and the stage for reducing the number of repetitive transmissions of the original transmission signal by the remote control transmitter is also increased. In response to this, the effective arrival number of demodulated signals on the remote control receiver side may be changed in multiple stages.

Instead of inserting the repetition count flag into the original transmission signal, another method may be used to notify the remote control receiver side of the decrease in the repetition count. For example, when it is first determined that the remaining capacity is insufficient, the decrease in the number of repeated transmissions may be notified only once, and the remote control receiver may perform the process of the decrease after the notification.

Further, when the remaining capacity is insufficient, the remote control transmitter reduces the number of repetitive transmissions of the original transmission signal, but the remote control receiver may perform the same processing as the conventional one. For example, in the case where the remote control transmitter repeatedly transmits the original transmission signal five times when the remaining capacity is sufficient and only three times when the remaining capacity is insufficient, the remote control receiver always transmits the same demodulated signal. May be performed when three are received.

Further, in the above description, a case is described in which it is confirmed whether a predetermined number of demodulated signals having the same content have arrived on the basis of the demodulated signal that has arrived first. The validity / invalidity of the demodulated signal may be determined based on whether or not a predetermined number of demodulated signals having the same content exist in the demodulated signal is not a reference.

(G) Other Embodiments In the above description, various modified embodiments have been described, but the following modified embodiments can be further mentioned.

In each of the above embodiments, the instructions issued by the remote control transmitter indicate “opening operation”, “closing operation”, and “stopping operation”. Is also good. For example, "exhaust and ventilation" for instructing a transition from a fully closed state or a fully open state to a partially open state required for exhaust and ventilation may be provided. In addition, the remote controller may be able to instruct “lock” and “unlock”.

In relation to the fourth embodiment, the battery 1
In the case where the remaining capacity of No. 6 is considerably small, some of the operation contents (not limited to one type) for accepting a key operation may be appropriately selected according to the operation type. Some remote control transmitters can issue instructions to a plurality of remote control receivers (for example, having a receiver selection key).
When the remaining capacity of No. 6 becomes insufficient, the remote control transmitter to which the instruction is transmitted may be limited by the remote control transmitter. The selection in this case may be left to the user.

In each of the above-described embodiments, the operation of notifying that the remaining capacity is insufficient at the time of key operation has been described. However, the operation may be continued after the operation becomes insufficient. For example, a dedicated light-emitting element that indicates that the light-emitting element is insufficient may be provided, and after the light-emitting element becomes insufficient, the light-emitting element may be continuously turned on.

The voltage of the battery 16 may decrease when the key operation is repeated within a short time, and may increase slightly when the interval between key operations is increased. For this reason, if the voltage monitoring monitors insufficient, there may be a case where sufficient notification is given after insufficient notification is given. For this reason, a flag may be set when insufficient is detected for the first time, or a flag may be set when insufficient is detected a plurality of times, to prevent the notification operations from being mixed.

In the above description, “change of transmission method” when the battery capacity becomes insufficient refers to a change in the amplification gain of the power amplifier, a change in the number of transmission frames per operation, or an instruction to transmit. Although the operation was limited, other methods may be used. For example, a change in the transmission control procedure other than the change in the number of transmission frames may be used. Examples of changes in the transmission control procedure include a change in the number of retransmissions when an error occurs (in the case of a remote control system that returns a response of receiving an instruction from the remote control receiver to the remote control transmitter as described later), and a simple transmission control procedure (for example, To free run).

In the above description, the criterion (threshold) for changing the transmission method when the remaining capacity of the battery is insufficient is stricter than the criterion (threshold) for notifying the insufficient remaining capacity of the battery. However, these criteria may be the same, or may be reversed from the above description.

Further, it goes without saying that a remote control system may be constructed by appropriately combining the features of the above embodiments.

In each of the above embodiments,
Although the remote control transmitter has only a transmission function, the remote control transmitter may be provided with a receiving unit that can receive a response signal indicating that an instruction has been received from the remote control receiver.

Further, in each of the above embodiments, the notification of the insufficient remaining capacity of the battery is performed by the notification unit of the remote control transmitter, but another notification method may be applied.
For example, notification of the fact to the remote control receiver may be adopted as a notification method. In this case, the remote control receiver sounds a buzzer or notifies a central control device that manages a plurality of remote control transmitters.

In the first embodiment, an example is given in which a buzzer sound indicating that a key operation has been accepted is changed and notified when the remaining battery capacity is sufficient or insufficient. By other methods, the operation mode may be changed between the case where the remaining capacity of the battery is sufficient and the case where the remaining capacity is insufficient, so that the notification function is exerted. For example, when the remaining capacity of the battery is insufficient, the movement speed of the opening / closing body may be changed to a normal speed, or the opening / closing body may be jerkyly moved to be notified.

The term "notification" in the claims includes the following cases.

In each of the above embodiments, the present invention is applied to a shutter remote control system.
The present invention may be applied to a remote control system of an opening / closing device that generally controls an opening / closing body such as a window, an overhead door, a gate, a gate (a gate of a parking lot or the like), a roll screen (for example, a light shielding film), a blind, and an awning device. .

The remote control system, the remote control transmitter, and the remote control receiver according to the present invention include those in which the remote control transmitter and the remote control receiver are connected by wire. However,
It is necessary that a predetermined portion (for example, a portion for performing key operation processing) of the remote control transmitter receives power supply from a built-in battery.

The remote control system, the remote control transmitter, and the remote control receiver according to the present invention may not require an operation by an operator (although it does not conform to the general term “remote control”). . For example, there is an opening and closing device in which an obstacle sensing device is provided at the end of the closing side of the opening and closing device, but the transmitter at the time of the detection remotely controls the operation of the opening and closing device. The technical idea of the present invention can be applied as a remaining capacity monitoring function. The scope of the claims includes such cases.

Further, in each of the above-described embodiments, the transmission medium in the wireless line is a radio wave, but may be an infrared ray. In this case, a photoelectric conversion unit or an electro-optical conversion unit is used instead of the antenna.

[0165]

As described above, according to the remote control transmitter for a switchgear, the remote control receiver for a switchgear, and the remote control system for a switchgear of the present invention, the period during which the state change of the switchgear cannot be instructed can be minimized. The convenience of the transmitter can be almost always exhibited.
