Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone having a sensor function.

[0002]

2. Description of the Related Art As a conventional technique relating to the present invention, there are various remote monitoring devices (security systems) for the purpose of crime prevention and disaster prevention using a telephone line, and an abnormality occurs in a sensor signal connected to the security device. In this case, there is a communication modem (interface device) that automatically dials a predetermined telephone and notifies the abnormality. But,
There is only one conventional interface device, which is completely independent of the telephone and has a different installation location. In addition, various sensors are usually arranged in each room and wired to the interface device. As one example, there is a home automation system, and a full-scale security system constituted by a home bus system is also realized. However, in these systems, the interface unit is the core and the telephone is only a voice terminal device.
Since such a home automation system requires a large amount of wiring work, it was not economical to introduce the system unless the housing was newly built or remodeled. In addition, once the system was constructed, there was a drawback that it lacked flexibility when remodeling.

On the other hand, a telephone with a built-in sensor has been conventionally devised, and various patents have been filed. These are roughly classified into two types, and one is for security / remote control. For example, Japanese Patent Laid-Open No. 2-67068
The gazette "button telephone device" is a telephone device having a built-in temperature sensor, which has a function of automatically reporting a fire when the temperature rises above a preset temperature, or Japanese Patent Laid-Open No. Hei 3
-159000 publication "Building environment management system" and JP-A-4-9535 publication "Air conditioning network system".
As described above, a system has been invented in which information of a temperature sensor built in a telephone is centrally managed by a private branch exchange and is useful for disaster prevention and air conditioning control. However, these telephones with a built-in sensor have only a function as a sensor terminal and only unilaterally report an abnormal signal to the private branch exchange side, and no countermeasures against malfunctions inherent to the sensor have been taken. That is,
The sensor built into the phone was a single function and not intelligent.

The other one is intended to support telephone conversation. For example, Japanese Unexamined Patent Publication No. 62-90062 “button telephone” and Japanese Unexamined Patent Publication No. 62-90064 “button telephone device” are telephones having a built-in optical sensor, and the optical sensor detects this when the surroundings of the telephone become dark. However, the display board and the like are automatically illuminated. Also, JP-A-62-20089
The "button telephone device" of Japanese Patent No. 6 is a telephone with a built-in human detection sensor, which detects the absence of the telephone user and automatically transfers the absence. It has been difficult to apply the conventional automatic illumination of a telephone with an optical sensor to a wireless telephone such as a cordless telephone because the secondary battery is consumed so much.

As described above, the common features of the prior art are that the sensor has a single function and no countermeasures against malfunctions associated with the sensor are taken, so that the reliability as a security system is low, and sensor information processing is performed with a telephone with a built-in sensor. Is performed in another main unit or private branch exchange, and the telephone is only a sensor terminal. Therefore, the telephone with the built-in sensor according to the conventional invention has a problem in practical use, and is not widely used.

By the way, in recent years, wireless type telephones such as cordless telephones, mobile telephones and car telephones have been explosively prevailed. Since these wireless phones are used as mobile phones, they usually use a secondary battery as a power source. The secondary battery must be charged without fail, and charging is performed using a dedicated charger. This charger is used, for example, in the form of a charging stand on which a cordless telephone handset is mounted on the charger. When the telephone is not used for a long time such as at night, the cordless telephone handset is usually placed on a charging stand for charging. The present inventor analyzed the usage pattern of the wireless telephone, and came to the conclusion that security and the wireless telephone are very compatible with each other. That is, from the viewpoint of crime prevention and disaster prevention, when the wireless telephone is not used for a long time, that is, when the wireless telephone is being charged, no person is present, and crime prevention and disaster prevention are required. . Of course, there are no wireless type telephones such as commercially available cordless telephones that satisfy the object of the present invention.

[0007]

In the conventional telephone with a built-in sensor for the purpose of communication support, the optical sensor makes it easy to make a telephone call by illuminating the location of the telephone, the push button, etc. by the human detection sensor, and automatically. It is difficult to achieve compatibility with security for the purpose of crime prevention because it is an unattended transfer. Further, reduction in power consumption is especially required for wireless telephones. On the other hand, in the case of a sensor-equipped telephone equipped with a security sensor for detecting fire by a temperature sensor, since the sensor has a single function, malfunction countermeasures are incomplete and reliability is low.

An object of the present invention is to use a sensor built-in a telephone and a sensor built-in a sensor-equipped charging stand independently or in cooperation with each other, thereby improving the convenience of the telephone, which has been a contradictory issue in the past. It is an object of the present invention to provide a wireless sensor phone that simultaneously realizes call support and highly reliable security for crime prevention.

[0009]

The present invention comprises a wireless telephone main body and a detachable sensor-equipped charging stand on which a sensor is mounted, and both the wireless telephone main body and the sensor-equipped charging stand include a human detection sensor. A wireless telephone having a built-in optical sensor, an independent sensor signal processing circuit, and a signal coupling mechanism for both sensor signals, wherein the sensor-equipped charging stand has a charging mechanism for the wireless telephone body, on the other hand,
The main body of the wireless telephone is provided with an automatic dial circuit for a preregistered telephone number and a voice notification circuit, and the sensor signal processing circuit selects one of a call support mode and a security mode depending on the situation. It is characterized by being.

Further, according to the present invention, in the security mode of the sensor signal processing circuit, the human detection sensor on the wireless telephone main body side and the human detection sensor on the sensor-equipped charging stand side simultaneously become abnormal after a lapse of a certain time from the mode setting. It is characterized in that the crime prevention abnormality is reported by an extension line or an outside line through a telephone line only when the security is detected.

Further, according to the present invention, the switching between the security mode and the call support mode is remotely executed by an infrared remote controller.

Further, according to the present invention, the security mode is released by turning off the power source of the sensor-equipped charging stand.

Furthermore, according to the present invention, the sensor signal processing circuit of the main body of the wireless telephone is configured so that, in the call support mode, the human detection sensor on the main body of the wireless telephone detects the approach of the caller and pushes the main body of the wireless telephone. The button display is turned on.

Further, according to the present invention, in the sensor signal processing circuit of the sensor-equipped charging stand, in the call support mode, the human detection sensor of the sensor-equipped charging stand senses the approach of a person, and the display of the sensor-equipped charging stand is displayed. Is lit up.

[0015]

According to the sensor telephone of the present invention, the security mode can be selected when the sensor telephone main body is placed on the sensor-equipped charging stand and is being charged.

When the security mode is selected by the method described below, an illegal intrusion of an extension line or an outside line occurs only when the human detection sensor built in the sensor telephone main body and the human detection sensor built-in the sensor-equipped charging stand simultaneously detect an abnormality. Make a crime report with someone.

Further, in the security mode, operability at the time of setting / releasing the automatic notification function becomes a particular problem.
In other words, if the user is inadvertently approached at the time of cancellation, it is regarded as an intruder and a message is sent. Therefore, when returning to home, it was conventionally necessary to call the home in advance to cancel the security mode, but in the case of the sensor telephone of the present invention, it can be remotely set / released by the attached infrared remote controller. , It is possible to avoid that the user is regarded as an intruder and the crime prevention report is sent to the outside.

Further, the power source of the sensor-equipped charging stand is turned off.
(Reset) cancels the security mode,
When the power is turned on again, the call support mode is set. Therefore,
If you break the breaker at the entrance when you go home, you can safely enter the room. Further, when the security mode is set, it is possible to directly operate the sensor remote by using the infrared remote controller or the sensor mode changeover switch of the sensor-equipped charging stand. In this case, since the timer starts after a certain period of time (for example, 3 minutes), it is possible to avoid erroneous notification of crime prevention during setting.

On the other hand, in the call support mode, when the approach of the telephone user is detected by the human detection sensor and the surroundings of the telephone are dark by the built-in optical sensor, the push button is lit to notify the location of the telephone and the dialing is performed. Easy to operate. Similarly, the sensor-equipped charging stand detects the approach of the telephone user by the human detection sensor, and the built-in optical sensor turns on the illumination lamp when the surroundings of the sensor-equipped charging stand are dark, and Notify whereabouts. In this way, since the sensor output is controlled by the logical product of the two sensor signals, in the security mode, the crime prevention notification due to the malfunction of the sensor is prevented, and the reliability can be greatly improved. Further, in the call support mode, the display and the like are turned on only when necessary, so that the power consumption can be reduced and the life of the secondary battery of the wireless telephone body can be effectively extended.

Although various types of human detection sensors having various principles are commercially available, for the purpose of the present invention, for example, a pyroelectric type human detection sensor is provided on the wireless telephone main body side and a sensor-equipped charging stand side. For this, a semiconductor pressure sensor type human detection sensor is desirable. This is because the pyroelectric type human detection sensor is a passive sensor and has the lowest power consumption, which is preferable in terms of secondary battery life. Further, the semiconductor pressure sensor type human detection sensor can detect a slight change in air pressure due to opening and closing of a door, etc., and therefore has no detection direction dependency and is excellent in remote monitoring. On the other hand, the drawback of this sensor is
Since it reacts to drafts when used alone, there was a problem in terms of malfunction. In the case of the sensor telephone of the present invention, 2
Since a type of human detection sensor is used and a crime prevention notification is made only when two human detection sensors detect a person at the same time, the security sensor is completely free of malfunctions. Of course, the human detection sensor is made of a dielectric and a Si semiconductor, respectively, and has no problem in terms of sensor life, and it is easy to miniaturize the sensor by microfabrication technology. Therefore, it is suitable for being built into a wireless telephone body or the like. ing.

The person detecting sensor is not limited to the one having the above-mentioned principle, and a plurality of person detecting sensors having the same principle can be used as a matter of course. The point of sensor selection is
Whether or not it is possible to construct a highly reliable security system that does not malfunction with multiple sensors. Any sensor that meets this purpose can be used.

According to the sensor telephone of the present invention, when the sensor telephone main body is mounted on the sensor-equipped charging stand and charging is started, the security mode can be selected. When the security mode is selected, the human detection sensor signal from the sensor-equipped charging base is electrically coupled to the wireless telephone body by the signal coupling mechanism described below. The automatic dial function works only when the sensor signal is transmitted to the main body of the type telephone and the human detection sensor of the main body of the wireless type telephone also detects an abnormal signal at the same time, and an internal or external line is audibly notified of a crime prevention abnormality. Although the part for performing the logical product process of the two sensor signals is on the wireless telephone body side in the above description, it may be performed on the sensor charging base side. in this case,
An automatic dial command is sent from the sensor-equipped charging stand to the wireless telephone body.

[0023]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, in order to facilitate understanding of the present invention, various functions and the like provided in the sensor telephone of the present invention will be described in advance before describing the embodiments of the present invention.

First, the sensor-equipped charging stand will be described. The sensor-equipped charging stand has a built-in optical sensor and human detection sensor,
It consists of a charging mechanism for the main body of the wireless telephone, a signal coupling mechanism, a sensor signal processing function, an infrared remote control function, an indicator lamp, and a sensor mode switch. As the human detection sensor, for example, a semiconductor pressure type sensor is used. The photosensor may be either a photodiode or a phototransistor.

The sensor signal processing function automatically switches to the call support mode when the main body of the wireless telephone is not on the sensor-equipped charging stand or when the power is cut off.
Operates with an independent sensor system function. That is, when the light sensor has a brightness equal to or lower than the preset brightness, and when the human detection sensor is activated, the switch circuit of the indicator lamp is activated, the indicator lamp is turned on, and the location of the sensor-equipped charging base is changed to a person. There is a function to inform. Therefore, it is convenient when charging the wireless telephone body in the dark.

When the wireless telephone body is being charged on the sensor-equipped charging stand, it is possible to select the security mode. When the security mode is selected, when the human detection sensor is activated, it will be described later. A signal is transmitted to the wireless telephone body through the signal coupling mechanism. Alternatively,
It is also possible to receive a human detection sensor signal from the wireless telephone body side through the signal coupling mechanism, perform a logical product process with its own human detection sensor signal, and then issue an automatic dial command to the wireless telephone body through the signal coupling mechanism. Good.

The sensor-equipped charging stand is provided with a sensor mode switch, and when the switch is turned on,
The security mode described above is activated. The reason for doing this is that the user may charge the wireless telephone body while staying in the room, and in the security mode there is a risk of falsely reporting the user as an intruder.
This is also because the call support mode is more convenient when charging at home while charging. The security mode is started after a lapse of a certain time (for example, 3 minutes) after the switch is turned on. In addition, the sensor-equipped charging stand is equipped with an infrared remote control function consisting of an infrared remote control light receiving part and an infrared remote control interface circuit, and switching to the security mode can be performed remotely with the attached infrared remote control. .

Next, the signal coupling mechanism will be described. The signal coupling mechanism is provided on both the charging base with the sensor and the main body of the wireless telephone, and may use either a contact method or a non-contact method. In the case of the contact method, for example, when the signal transmission is performed by the contact pieces provided on both the sensor-equipped charging stand and the wireless telephone body, the electrical continuity is surely secured when the wireless telephone body is mounted on the sensor-equipped charging stand. Since it has to be provided, the contact piece on one side needs to be supported by an elastic body. In addition, from the viewpoint of malfunction or safety when not mounted, it is desirable that these contact pieces are not exposed to the outside from the sensor-equipped charging stand and the wireless telephone body. In the case of the non-contact method, there is a method of electromagnetically coupling with a known built-in transformer. It is superior in safety, durability, and reliability compared to the contact method, but when reducing the pitch between transmission lines, it is necessary to consider crosstalk due to leakage of magnetic flux. Further, as a non-contact method, it is also possible to adopt an optical coupling method such as opto-electrical (OE) signal conversion and making the end faces of the optical fibers face each other. As described above, the signal coupling mechanism can be appropriately selected from known signal transmission systems.

The charging mechanism may be implemented by a commercially available cordless telephone, that is, a method of converting 100V into, for example, 3.6V by an independent power adapter and supplying it to the sensor telephone main body. But,
By incorporating the voltage converter into the sensor-equipped charging stand, it is possible to take a neat shape in terms of design. Power supply from the sensor-equipped charging stand to the sensor phone body
The method using contact pieces which is generally used at present is preferable. For example, when the main body of the wireless telephone is mounted on the sensor-equipped charging stand, displacement of the contact piece senses the mounting, and charging is immediately started.

Next, the main body of the wireless telephone will be described. The wireless telephone body has a built-in optical sensor and human detection sensor, a signal coupling mechanism with a sensor-equipped charging stand, a sensor signal processing function, a function for automatically dialing a pre-registered telephone, and a function for reporting a sensor abnormality by voice. And push button (P
At least the indicator light of B) is provided. As the built-in human detection sensor, for example, a pyroelectric type sensor is used. The photosensor may be either a photodiode or a phototransistor, and may be appropriately selected from commercial products.

The sensor signal processing function has almost the same function as that of the sensor-equipped charging stand described above. In other words, if the wireless telephone body is not on the sensor-equipped charging stand, it operates in the call support mode, when the optical sensor has a brightness equal to or lower than the preset brightness, and when the human detection sensor detects a person, the PB
Since the switch circuit of the indicator lamp is activated and the indicator lamp is turned on, it is convenient when dialing the telephone. The PB indicator lamp can be easily realized by incorporating an LED in the PB, for example.

When the main body of the wireless telephone is being charged on the sensor-equipped charging stand, the security mode can be selected as described for the sensor-equipped charging stand. The AND processing of both human detection sensors may be added to the sensor signal processing function of either or both of the wireless telephone body side and the sensor-equipped charging stand side.

Although the method of not using the optical sensor signal in the security mode has been described, a method of using the optical sensor signal in the security mode is also possible in order to further secure the malfunction countermeasure. For example, a sensor-equipped charging stand has a built-in clock function, and it is determined that there is an intruder when the optical sensor operates at night when there is nobody,
By performing a logical product process with a human detection sensor, it is possible to reliably detect an intruder at night. Further, when the voice notification of the crime prevention abnormality is received by the automatic dialing, the receiver can switch to the known room monitor function by the PB signal and know the presence of the person in the room through the receiver. By doing so, it is possible to check whether or not the user is an intruder, and the reliability of this security system is further improved. Also,
At the time of notification, it is possible to select stop or continuation of the security mode by a predetermined PB signal.

For the voice call function, for example, the prepared voice message "Emergency call! Emergency call! This is XXXXX. The thief has entered! The thief has entered!" It is something to convey.

The function of the present invention has been described above. To summarize the features of the present invention, the sensor telephone of the present invention has a plurality of sensors built in the wireless telephone main body and the sensor-equipped charging stand, both of which are independent or The point is that the logical product processing of the sensor signals is performed in cooperation with each other. Therefore, in the security mode, by mounting a sensor having a different operation principle, it is possible to prevent a malfunction that has been a problem in the past. In the call support mode, it is possible to reduce power consumption and improve operability, which are essential conditions for the wireless telephone body.

Further, the sensor telephone of the present invention can be expanded in various ways by taking advantage of the above characteristics. For example, in the security mode, it is possible to provide an automatic response circuit and a PB signal analysis circuit in the main body of the sensor telephone, and monitor a plurality of built-in sensor information by voice response from outside the house with a PB signal. In the call support mode, for example,
By incorporating a sound sensor that detects the ringing sound from the outside line, it is possible to detect the approach of the caller and automatically switch to the hands-free call mode. <Example> The following is only one example of the present invention and does not limit the technical scope of the present invention.

FIG. 1 is an external perspective view of a sensor-equipped charging stand and a wireless telephone body, and FIG. 2 is a diagram of the present invention produced by adding a sensor system of the present invention to a low-power cordless answering machine (with room monitor function). FIG. 3 is a schematic view of a circuit block diagram, and FIG. 3 is a flowchart of the main operation of the sensor telephone of the present invention.

In FIG. 1, the sensor-equipped charging stand 100 is connected to a 100V commercial power source, and a wireless telephone main body 200 is provided.
Working independently of the semiconductor pressure sensor type human detection sensor 1
a, a phototransistor type optical sensor 2a is built in, and a signal coupling mechanism and a charge coupling mechanism with the wireless telephone body 200 are provided. Further, a sensor mode changeover switch 5 and an illumination lamp 8 with a clock interlocked with the sensor signal,
Infrared remote control light receiver 6-1 and charging station 100 with sensor
Is attached to the front panel of. The sensor mode changeover switch 5 has a built-in illumination, and the green lamp lights up when the call support mode is selected and the red lamp lights up when the security mode is selected. You can check the color. Further, the sensor-equipped charging stand 100 has a charging contact piece 21A and signal coupling contact pieces 22A and 23A.
And are provided at positions where the wireless telephone body 200 is accommodated. In addition, 9 is a power plug and 10 is a power circuit.

On the other hand, the wireless telephone body 200 has a built-in person detection sensor 1b and a photodiode type optical sensor 2b, and a push button has a built-in PB indicator lamp 30 linked with the sensor signal. The human detection sensor 1b is of a pyroelectric type and has a wide detection area of about 180 degrees. The optical sensor 2b is provided on the side surface of the handset. The position of the optical sensor 2b is preferably a position where it is not covered with ears or hands during a call as described above. Because, when the optical sensor 2b is hidden, both the human detection sensor 1b and the optical sensor 2b are activated, so that the PB indicator lamp 30 is turned on during a call in which illumination is unnecessary, and the secondary battery 40 is consumed. Because it will speed up. In addition, 34 is a microphone, 3
Reference numeral 5 is a speaker and 36 is an antenna.

When the wireless telephone body 200 is mounted on the sensor-equipped charging stand 100, charging is started via the charging contact pieces 21A provided on both sides, and at the same time, the signal coupling contact pieces 22A, 23A provided on both sides. It becomes possible to transmit a sensor signal and an automatic dial command signal respectively via. In FIG. 1B, the charging contact piece and the signal coupling contact piece (21B, 22 in FIG. 2) on the wireless telephone body 200 side.
(B, 23B) are not shown.

In the circuit block diagram of FIG. 2, the upper side surrounded by the chain double-dashed line is a main circuit block diagram of the sensor-equipped charging stand 100 and the lower side is the main body of the wireless telephone 200.
First, the sensor-equipped charging stand 100 will be described.

In this embodiment, the sensor signals of the human detection sensor 1a and the optical sensor 2a are logically ANDed by the sensor signal processing circuit 3A. The operation of the sensor signal processing circuit 3A is performed by the charge detection circuit 4A, the infrared remote control interface circuit 6,
It is controlled by the output of the human detection signal 3Bc transmitted from the timer circuit 7 and the sensor processing circuit 3B of the wireless telephone body 200. That is, the charge detection circuit 4
It is checked by A whether the battery is being charged. If the battery is being charged, the call support mode can be switched to the security mode by the infrared remote controller 6-2 or the sensor mode changeover switch 5. Sensor signal processing circuit 3
In the call support mode, A controls ON / OFF of the illumination of the illumination lamp 8 by a logical product process of signals from the human detection sensor 1a and the optical sensor 2a. In security mode,
As shown in the flow chart described later, the timer circuit 7
When the security monitoring is started after the lapse of minutes and the human detection sensor 1a on the sensor-equipped charging stand 100 side is activated, the human detection sensor signal 3Bc of the sensor signal processing circuit 3B on the wireless telephone body 200 side is referred to. Human detection sensor 1
Only when both a and 1b are operated, the automatic dial command signal 3Ac is transmitted to the wireless telephone body 200 side.

The sensor-equipped charging stand 100 of the present invention has a charging function similar to that of a conventional cordless telephone. However, since the charging circuit 11 that converts the voltage of 100 V is built in, the conventionally used charging adapter is unnecessary. The wireless telephone body 200 is equipped with a sensor, and the charging stand 100 is mounted.
Then, the charging circuit 11 operates to charge the secondary battery 40 of the wireless telephone body 200 via the charge coupling mechanism 21.

Next, the wireless telephone body 200 will be described. Whether or not the wireless telephone body 200 is on the sensor-equipped charging base 100 is checked by the charge detection circuit 4B. If it is not on the base, the wireless telephone body 200 operates in the call support mode, and the pyroelectric type built into the wireless telephone body 200 is used. The sensor signals of the human detection sensor 1b and the optical sensor 2b are logically ANDed by the sensor signal processing circuit 3B, and the PB indicator lamp 30 is turned ON-OF.
F control. On the other hand, when it is on the sensor-equipped charging base 100, the wireless telephone body 200 is automatically switched to the security mode, and the output of the human detection sensor 1b is mounted on the sensor via the sensor signal processing circuit 3B and the signal coupling mechanism 22. It is transmitted to the sensor signal processing circuit 3A on the charging stand 100 side. Therefore, in this embodiment, the wireless telephone body 200 does not have the call support mode during charging and the illumination function of the PB indicator lamp 30 is stopped.

As described above, the charging stand 1 with the sensor installed.
On the 00 side, when the wireless telephone body 200 is installed, the security mode is manually selected by the sensor mode changeover switch 5 or the infrared remote controller 6-2. At this time, if the mode is not changed, the person detection signal 3Bc transmitted from the wireless telephone body 200 side is not used and is discarded because it is operating in the call support mode.

When the sensor-equipped charging base 100 side is in the security mode, and when the human detection sensors 1a and 1b are both activated, an automatic dial command signal is sent from the sensor signal processing circuit 3A to the wireless telephone body 200 side via the signal coupling mechanism 23. 3Ac is transmitted, and the automatic dial circuit 32 and the voice reporting circuit 33 voice report a crime prevention error to a telephone registered in advance. In the block diagram of FIG. 2, the original function of the cordless telephone is abbreviated as the call control circuit 31. The automatic dial circuit 32 and the voice notification circuit 33 are incorporated in the call control circuit 31.

Next, a flow chart of the main operation of the sensor telephone of the present invention is shown in FIG. Note that (1) to
(11) shows each step. First, it is checked whether the phone is charging (1), if it is charging, it is checked whether the security mode is selected (2), and if the security mode is selected, 5 minutes after the timer elapses (3). The security mode starts from. When the human detection sensor 1a of the sensor-equipped charging stand 100 operates (4) and further the human detection sensor 1b of the wireless telephone body 200 operates (5), the voice notification circuit 33 operates (6). When the human detection sensors 1a and 1b do not operate, it is checked whether or not the mode is switched (7), and then the process returns to the security loop. On the other hand, when charging is not being performed, the wireless telephone body 200 and the sensor-equipped charging stand 100 independently enter the communication support mode, the human detection sensors 1a and 1b are activated (8), and the outputs of the optical sensors 2a and 2b are constant. If it is lower than the value (9), the illumination lamp 8 is turned on (10), and if any of the conditions is not satisfied, the illumination lamp 8 is turned off (1).
1) Then, it returns to the first loop again.

As described above, the sensor signal processing circuit 3A,
3B controls the central function of the sensor system of the sensor telephone, and in the case of the security mode, in this embodiment, the sensor processing circuit 3A on the sensor-equipped charging stand 100 side.
The automatic dial command is issued to the main body 200 of the wireless telephone by the function of. Further, the sensor-equipped charging base 100 side uses the pressure type human detection sensor 1a, and the wireless telephone body 200 side uses the pyroelectric type human detection sensor 1b. However, these two types of sensors have different characteristics, and thus malfunction. It is possible to perform signal processing that reliably detects a person. The pressure type human detection sensor 1a is sensitive to a change in the air pressure in the room when the door is opened and closed, and has a detection distance of about 5 m. On the other hand, the working distance of the pyroelectric type human detection sensor 1b is shorter than that and is about 3 m. Therefore, in the present embodiment, first, the operation of the pressure type human detection sensor 1a is checked, and if it is operated, the operation of the pyroelectric type human detection sensor 1b is checked while holding the signal for 3 minutes. . Of course, the method is not limited to this method, and the sensor signal processing circuit 3 may be selected according to the characteristics of the sensor element used.
Just tune A and 3B.

In the present embodiment, as is clear from the above-mentioned flowchart, when a security abnormality occurs and automatic dial notification is made, the security function and the call support function can be obtained by placing the handset of the destination telephone. Stop. After returning home, the power supply of the sensor-equipped charging stand 100 is once turned off and reset, whereby the communication support mode function is restarted. The reset circuit is omitted in FIG.

On the other hand, the main body of the wireless telephone has an automatic dial circuit for a registered telephone number and a voice notification circuit, and the sensor signal processing circuit further selects either a call support mode or a security mode depending on the situation. Therefore, the first feature is that the same sensor can be used separately for the call support mode and the security mode depending on the situation, and the phone can be used comfortably at home,
When you are out of the office, you can go out with peace of mind by automatically reporting a crime prevention alarm to your out-of-home phone. The second feature is that multiple sensors are used in cooperation in each mode,
The sensor is being made intelligent. Therefore, in the call support mode, battery consumption of the secondary battery can be minimized, and in the security mode, erroneous operation inherent to the sensor can be prevented, so that a highly reliable crime prevention system is realized. . The third feature is the flexibility of the security system. That is, in the conventional home security, a large amount of wiring work was required, but according to the sensor telephone of the present invention, the sensor telephone is used as a cordless sensor signal transmission medium.
