As a sensor unit for detecting a change in the external environment, for example, a gas sensor such as a CO sensor, a city gas sensor, or an LP gas sensor has been used.
When the sensor unit is, for example, a gas detection element, the microcomputer circuit receives an alarm signal from the microcomputer circuit and issues an alarm by sound when the microcomputer circuit determines that the sensor unit continuously detects the gas to be detected that is above the alarm level. It was composed.

  In such an alarm system, in order to confirm the normality of the alarm function, there is an alarm system provided with an inspection function that allows an operator to inspect the alarm system at the installation location. The inspection function automatically diagnoses each function of the alarm system when the operator operates the inspection switch when no abnormality in the external environment is detected. For the inspection, for example, by operating an inspection switch, an indicator lamp for alarming the occurrence of fire or gas is turned on for a predetermined time, or a buzzer sound or a voice message is output from the speaker. At this time, in the alarm system that automatically shuts off the gas main plug by performing a voltage output to the gas microcomputer meter outside the house at the time of gas detection, the voltage output at the time of gas detection is also output for a predetermined time even during inspection. As a result, the gas microcomputer meter shuts off the main gas plug.

  In addition, since the alarm system mentioned above used as the prior art in this invention is a general technique, prior art documents, such as a patent document, are not shown.

  When the alarm system is, for example, a gas alarm device, the gas alarm device is usually disposed at a high position near the ceiling on the wall surface. In this case, when the operator operates the inspection operation means that is the inspection switch, it is necessary to operate the inspection operation means of the gas alarm arranged at a high position. Since there was a case where it performed, the operation at the time of inspection was complicated.

  Accordingly, an object of the present invention is to provide an alarm system that is easy to operate.

An alarm system according to the present invention for achieving the above object is an alarm system that detects an abnormality in the external environment and issues an alarm, the first feature of which is a sensor unit that detects a change in the external environment, an abnormality An alarm main body comprising alarm output means for outputting an alarm upon occurrence, and first instruction accepting means capable of accepting an operation instruction to the alarm system; and the alarm main body separately from the alarm main body A remote control device comprising a second instruction receiving means capable of communicating and capable of receiving an operation instruction to the alarm system, wherein the alarm device body includes the first instruction receiving means and the second instruction receiving a control means for controlling the operation of the alarm system when there is a reception instruction to the at least one means, said remote control device, remote control sensor unit for detecting a change in the external environment, and abnormal onset It lies in having a remote control alarm output means at an alarm output.

In this configuration, since the remote control device is provided separately from the main body of the alarm device and can be disposed at a position separated from the main body of the alarm device, the alarm device is carried by carrying the remote control device separate from the main body of the alarm device. The main body and the remote control device can be made communicable.
Therefore, according to this configuration, when the first instruction receiving means of the alarm device main body and the second instruction receiving means of the remote control device that can communicate with the alarm device main body separately from the alarm device main body have received instructions, respectively. In order to control a predetermined operation of the alarm system, the remote control device can be easily received (a low position on the wall surface) even when the alarm device body is disposed at a high position near the ceiling on the wall surface. Etc.), the operator can easily hold the remote control device and easily perform a predetermined operation of the alarm system.

The remote control side alarm output means may be configured to output an alarm in accordance with the alarm output from the alarm output means of the alarm device main body, that is, through communication from the alarm device main body. By doing in this way, even if it is a case where various alerting | reporting contents are in the place where a customer is away from the main body of an alarm device, possibility that it can be transmitted accurately can be improved.
In this configuration, the alarm is output from the alarm output means of the alarm device main body and the remote control side alarm output means of the remote control device from the beginning. Can be informed.
Further, in this configuration, it is possible to set an alarm that is not output from the alarm output means of the alarm device main body but is output only from the remote control side alarm output means of the remote control device.

  The second characteristic configuration of the alarm system according to the present invention is that, in the first instruction receiving unit and the second instruction receiving unit, the other does not receive a predetermined instruction until one receives a predetermined instruction. .

  According to this configuration, until one of the instructions is accepted, the other can be locked so as not to accept the instruction. Therefore, it is possible to apply a mode in which only one instruction is accepted.

  The third characteristic configuration of the alarm system according to the present invention is that the first instruction receiving unit and the second instruction receiving unit receive one instruction and the other instruction is received within a predetermined time. It is in the point which enabled it to do.

  According to this configuration, since it is necessary to accept instructions to the first instruction accepting unit and the second instruction accepting unit, it is possible to provide an operation method when performing a special inspection operation or the like that is not normally performed.

  A fourth characteristic configuration of the alarm system according to the present invention is that the first instruction accepting unit and the second instruction accepting unit are configured to instruct a plurality of operations by receiving different instructions.

  According to this configuration, when the first instruction receiving unit and the second instruction receiving unit are, for example, switch-shaped members, the inspection operation is started when the first instruction receiving unit is pressed for a short time, and the alarm is issued when the long pressing is performed. When the second instruction receiving means is pressed for a short time, the alarm is stopped. When the second instruction receiving means is pressed for a long time, the inspection operation can be started. Therefore, a desired operation instruction can be set by receiving different instructions.

  A fifth characteristic configuration of the alarm system according to the present invention is that when the first instruction receiving unit and the second instruction receiving unit receive an instruction for each within a predetermined time, an instruction with a higher priority is given. It is in the point made to perform.

  According to this configuration, priorities are set in advance in the first instruction receiving means and the second instruction receiving means, and instructions are received within a predetermined time for both the first instruction receiving means and the second instruction receiving means. The instruction with the higher priority can be executed.

It is the schematic of the alarm system of this invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The alarm system of the present invention detects an abnormality in the external environment and issues an alarm.
As shown in FIG. 1, the alarm system X of the present invention detects a change in the external environment based on the sensor unit 11 that detects a change in the external environment, and the output of the sensor unit 11. An alarm output unit 12 that transmits an alarm output to the alarm system X, and a first instruction receiving unit 13 that can receive an operation instruction to the alarm system X.
The alarm system X includes a remote control device 20 including a second instruction receiving unit 21 that can communicate with the alarm main body 10 separately from the alarm main body 10 and can receive an operation instruction of the alarm system X. .
The alarm device body 10 includes a control unit 15 that controls the operation of the alarm system X when at least one of the first instruction receiving unit 13 and the second instruction receiving unit 21 receives an instruction.

  The alarm main body 10 is disposed at a high position near the ceiling on the wall surface, for example. The alarm device body 10 includes a sensor unit 11 that detects changes in the external environment. As such a sensor unit 11, a gas sensor such as a combustible gas sensor, a CO sensor, a city gas sensor, and an LP gas sensor, a fire sensor, and the like can be used, but the present invention is not limited thereto.

The gas sensor may be in any form as long as it detects the gas to be detected. For example, a combustible gas sensor can detect a combustible gas such as hydrogen gas, an oxygen sensor can detect oxygen gas, a CO sensor can detect carbon monoxide gas generated by incomplete combustion, a city gas sensor can detect hydrocarbon gas, etc. Any known semiconductor sensor element, contact combustion sensor element, or the like can be used as long as it can detect the leaked gas.
As the fire sensor, a temperature sensor that senses an increase in temperature, a known scattered light smoke sensor having a smoke sensing function, or the like can be used.
This embodiment demonstrates the case where the combustible gas sensor, CO sensor, and fire sensor which detect methane, propane, etc. as a to-be-detected gas are equipped as the sensor part 11 at home.

  In this embodiment, the microcomputer circuit of the alarm output unit 12 indicates that the signal from the sensor unit 11 is transmitted to the alarm output unit 12 and continuously detects a gas to be detected that is higher than the alarm level or a temperature rise. When it is determined, the alarm operation may be performed, or the external device B may receive the alarm signal from the alarm output unit 12 and perform the alarm operation.

The alarm output means 12 performs a voltage output by the first voltage when an abnormality occurrence in the external environment is detected, and a second different from the first voltage at a normal time when a predetermined abnormality occurrence is not detected in the external environment. Performs voltage output by voltage. In any case, it is possible to perform an alarm operation for causing a buzzer sound or a voice message to sound from a speaker incorporated in the alarm system X and further blinking an LED incorporated in the alarm system X for a predetermined time.
For example, the external device B is incorporated in a gas microcomputer meter disposed at a position separated from the alarm system X or a monitoring unit. When the external device B is a gas microcomputer meter, the alarm operation can be performed, for example, to shut off a gas main plug.

  That is, the alarm output means 12 outputs a voltage according to, for example, the presence or absence of gas detection and the type of gas detected. For example, the alarm system X normally maintains 6v output, outputs 0v when there is an abnormality in the alarm system X, and combustible gas or CO is detected (hereinafter referred to as “when gas is detected”). Respectively outputs 12v and 18v. In the gas microcomputer meter which has received such a voltage output, if this voltage output is 12v or 18V, control is performed to automatically shut off the gas main plug.

  The first instruction receiving means 13 may be any form as long as it is a trigger that starts a predetermined operation of the alarm system X. For example, the first instruction receiving means 13 may be constituted by a switch-like member, Or the structure which receives an operation instruction in response to light may be sufficient. For example, when a switch-shaped member is used, the first instruction receiving means 13 may be operated in an arbitrary manner such as by long pressing, short pressing, or continuous pressing during operation. Examples of the predetermined operation include, but are not limited to, an operation of starting an inspection operation and stopping an alarm. The number of the first instruction receiving means 13 may be one or plural. When a plurality of the first instruction receiving means 13 are provided, each of the first instruction receiving means 13 may be caused to perform a different predetermined operation. Further, when a plurality of first instruction receiving means 13 are provided, the size and shape of each first instruction receiving means 13 may be changed. Thereby, each first instruction receiving means 13 can be easily identified.

  The remote control device 20 is configured by a housing different from the alarm device main body 10, and can be disposed separately from the alarm device main body 10 and at a position separated from the alarm device main body 10. For example, when the alarm device main body 10 is disposed at a high position near the ceiling on the wall surface, the remote control device 20 is usually preferably disposed in a place where the operator can easily obtain it. You may arrange | position in a low position and may arrange | position in the place different from the said wall surface.

  The remote control device 20 is configured to be able to communicate with the alarm main body 10. That is, the remote controller 20 may be configured to communicate with the alarm device body 10 by wired communication, wireless communication, or the like. These communications may be bidirectional communications or unidirectional communications. Wired communication can be performed by connecting the remote control device 20 and the alarm device body 10 by a known communication cable such as a USB or an optical fiber. Wireless communication is possible by providing each of the alarm device body 10 and the remote control device 20 with wireless communication means such as infrared communication.

In the present embodiment, a case where infrared communication (one-way communication) is applied as the wireless communication unit will be described. In other words, the alarm body 10 is provided with an infrared receiver 14 as a first communication means, and the remote controller 20 is provided with an infrared transmitter 22 as a second communication means, so that the remote controller 20 can communicate with the alarm body 10. It becomes. When bi-directional communication is adopted as the wireless communication means, a transmission / reception device capable of transmitting and receiving may be provided for each of the first communication means and the second communication means.
When the alarm main body 10 and the remote control device 20 are wirelessly communicated, and the driving system of the alarm system X is a battery type, the battery life can be extended by intermittently controlling the communication.

  The second instruction receiving means 21 provided in the remote control device 20 may be of any form as long as it is a trigger that starts a predetermined operation of the alarm system X. For example, the second instruction receiving means 21 is configured by a switch-like member. Alternatively, it may be configured to accept an operation instruction in response to sound or light. For example, in the case of a switch-like member, the operation may be performed in any manner such as long pressing, short pressing, or continuous pressing of the second instruction receiving means 21 during operation. The number of the second instruction receiving means 21 may be one or plural. When a plurality of second instruction receiving means 21 are provided, each second instruction receiving means 21 may be caused to perform a different predetermined operation. When a plurality of second instruction receiving means 21 are provided, the size and shape of each second instruction receiving means 21 may be changed. Thereby, each second instruction receiving means 21 can be easily identified. Further, when a plurality of second instruction receiving means 21 are provided, the infrared frequency at the time of wireless communication may be changed.

  The alarm system X according to the present invention provides the alarm device body 10 with a control unit 15 that controls the operation of the alarm system X when at least one of the first instruction receiving unit 13 and the second instruction receiving unit 21 receives an instruction. Prepare. In the present embodiment, the control unit 15 receives instructions from the first instruction receiving unit 13 of the alarm device body 10 and the second instruction receiving unit 21 of the remote control device 20 that can communicate with the alarm device body 10, respectively. A case will be described in which the alarm output means 12 performs a predetermined alarm output (start of inspection operation) and control is performed so as to stop the alarm output (stop alarm).

  For example, when the first instruction receiving unit 13 receives an instruction, the control unit 15 causes the alarm output unit 12 to output the first inspection alarm for the external device B, and the second instruction receiving unit 21 receives the instruction. If there is, control is performed to cause the alarm output means 12 to perform a second inspection alarm output different from the first inspection alarm output for the external device B.

  In this case, the alarm output means 12 performs a voltage output with the same first voltage as that when the occurrence of an abnormality in the external environment is detected as the first inspection alarm output, and as the second inspection alarm output in the external environment. What is necessary is just to perform the voltage output by the same 2nd voltage as the normal time when the predetermined | prescribed abnormality occurrence is not detected.

  In addition, when the first instruction receiving means 13 receives an instruction instead of the above-described mode, the second inspection alarm output (a voltage with the second voltage that is the same as the normal time when the predetermined abnormality is not detected) Output) is performed by the alarm output means 12, and when the second instruction receiving means 21 receives the instruction, the first inspection alarm output (the voltage output by the same first voltage as when the occurrence of abnormality is detected) ) May be controlled to be executed by the alarm output means 12.

  If the first instruction receiving means 13 or the second instruction receiving means 21 receives an instruction while the first inspection alarm output or the second inspection alarm output is issued, the alarm output is stopped. It is better to control it.

  The first instruction receiving means 13 and the second instruction receiving means 21 can be configured to instruct a plurality of operations by receiving different instructions. When the first instruction receiving unit 13 and the second instruction receiving unit 21 are, for example, switch-shaped members, the first instruction receiving unit 13 and the second instruction receiving unit 21 have the same operation (short press, long press, continuous press). In this case, control may be performed so that the same operation is instructed, and even if the same operation is performed, control may be performed so that different operations are instructed. For example, when the first instruction receiving means 13 is pressed for a short time, the inspection operation is started, and when the first instruction receiving means 13 is pressed for a long time, an alarm stop operation is performed. At this time, when the second instruction receiving means 21 is pressed for a short time, the alarm is stopped. When the second instruction receiving means 21 is pressed for a long time, the inspection operation is started.

  In addition, there may be an operation that can be executed only by operating the first instruction receiving means 13, and examples of such an operation include an inspection operation that is not normally performed that the customer does not want to perform.

  The alarm system X according to the present invention has instructions received by the first instruction receiving means 13 of the alarm device main body 10 and the second instruction receiving means 21 of the remote control device 20 separate from the alarm device main body 10, respectively. In order to control a predetermined operation of the alarm system X, the remote control device 20 can be easily received at a position (on the wall surface) even when the alarm body 10 is disposed at a high position near the ceiling on the wall surface. If it is disposed at a low position or the like, the operator can easily perform the predetermined operation of the alarm system X by holding the remote control device 20 in hand.

In the embodiment described above, when the first instruction receiving means 13 receives an instruction, the control means 15 causes the alarm output means 12 to output the first inspection warning and instructs the second instruction receiving means 21 to In the case where there is acceptance, the case has been described where control is performed so that the alarm output means 12 performs the second inspection alarm output. However, the present invention is not limited to such an embodiment, and the same inspection alarm output is sent to the alarm output means 12 regardless of whether the first instruction accepting means 13 and the second instruction accepting means 21 receive instructions. You may control so that it may be performed.

  When the first instruction receiving means 13 and the second instruction receiving means 21 receive the same instruction or different instructions at the same time (or within a predetermined time until the control based on the instruction reception is performed), The instruction may be canceled, or both instructions may be executed sequentially. For example, the first instruction accepting unit 13 and the second instruction accepting unit 21 are configured to set priorities in advance, execute an instruction with a higher priority, and cancel an instruction with a lower priority. Alternatively, the instructions may be executed sequentially from the instruction with the highest priority.

[Another embodiment 2]

That is, the remote control device 20 can be configured to communicate using an electrically connected method when the alarm device body 10 is mounted, and to communicate using a wireless method when the remote control device 20 is detached.
Further, the control means 15 of the alarm device body 10 may be configured to cut off the power supply to the wireless communication receiving unit when detecting that the remote control device 20 is mounted. In this way, power consumption due to wireless communication can be suppressed. In this case, it is preferable that the power supply to the wireless communication receiving unit be resumed when the remote control device 20 is disconnected.

[Another embodiment 3]
The first instruction receiving unit 13 and the second instruction receiving unit 21 may each include a lock mechanism that prevents the instruction from being received. In this case, for example, in the first instruction accepting unit 13 and the second instruction accepting unit 21, it is possible to prevent the other from accepting the predetermined instruction until one accepts the predetermined instruction. In this configuration, until one of the instructions is accepted, the other can be locked so as not to accept the instruction. Therefore, a mode in which only one instruction is accepted can be applied.

Further, each of the first instruction receiving means 13 and the second instruction receiving means 21 can be configured to operate the lock mechanism when an instruction is received more than a predetermined number of times within a predetermined time.
When such a lock mechanism is provided, a lock release mechanism for releasing the locked state may be provided.

The lock release mechanism may be provided in either the alarm device main body 10 or the remote control device 20, or may be provided in either one. Normally, the remote control device 20 is often arranged at an easy-to-operate position, and the possibility that an operation more than necessary is performed by a child or the like is higher than that of the alarm main body 10, so the lock release mechanism is the alarm main body 10. Is preferably provided.
In addition, when providing the lock release mechanism in the alarm device body 10, bidirectional communication is used. Further, the lock release mechanism may be a mechanism that releases the lock when the remote control device 20 is mounted on the alarm device body 10.
