As shown in FIG. 1, the alarm system X includes a plurality of alarm devices 10 and a remote control device 20 configured to be able to communicate with the alarm devices 10 separately from the alarm devices 10. In this embodiment, a case where two alarm device main bodies 10a and 10b are provided will be described. These alarm main bodies 10a and 10b may be arranged in different locations separated from each other in the same room, separately in each room of an adjacent room, or on different floors in a building. It may be arranged separately.

  The alarm device body 10 (for example, 10a) includes a detection unit 11 that detects a change in the external environment, a main body side communication unit 12 that can communicate with the remote control device 20 and another alarm device body 10 (for example, 10b), and a detection unit 11. Calculation means 13 for calculating the degree of change in the external environment based on the result detected by the computer, main body side storage means 14 for preliminarily storing its own identifier and a plurality of selectable alarm sound signals S2, and calculation means 13 When it is determined that a change in the external environment above the alarm level is detected, the alarm signal S1 is received from the calculation means 13, and any one of the alarm sound signals S2 stored in the main body side storage means 14 is output as the alarm sound S3. Alarm means 15.

  As the detection means 11, for example, any one of a city gas sensor, an LP gas sensor, a CO sensor, and a fire sensor may be provided. A city gas sensor can detect a leak gas such as hydrocarbon gas, an LP gas sensor can detect LP gas, and a CO sensor can detect carbon monoxide gas generated by incomplete combustion. A type sensor element or a catalytic combustion type gas sensor element can be used. 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 it is set as the alarm system X as the gas alarm device which applies the city gas sensor as the detection means 11. FIG.

  The main body side communication means 12 may be configured to be able to communicate with the remote control device 20 by wireless communication or the like, and the wireless communication is preferably bidirectional communication. In the present embodiment, a case where infrared communication is applied as the main body side communication unit 12 will be described. That is, the main body side communication means 12 can be configured by an infrared transmission / reception unit.

  The main body side communication means 12 can be configured to change the intensity and frequency of radio waves during transmission and reception. Thus, when the accuracy of communication with the remote control device 20 is low, the strength of radio waves and the frequency can be changed to improve the accuracy of communication with the remote control device 20.

  The calculation means 13 includes a concentration calculation unit that calculates the city gas concentration based on the output of the detection means 11 detecting the leakage of the city gas. The concentration calculation unit may use a microcomputer that can calculate the city gas concentration based on the output signal from the detection means 11.

  The main body side storage means 14 may be in any form as long as it is a memory or storage capable of storing its own identifier and a plurality of types of alarm sound signals S2. As the identifier, for example, an identification number that can identify each alarm device main body 10a, 10b can be used. However, the identifier is not limited to this, and position information indicating an installation location may be used. Further, the main body side storage means 14 may be configured to be able to store an identifier signal of itself or another alarm device main body.

  The multiple types of alarm sound signals S2 are, for example, synthesized sound signals required for home gas alarms (for example, synthesized speech such as “Does gas leak?”), And required for commercial gas alarms It is good to memorize | store two types of electronic sound signals (for example, electronic sounds, such as "a beep, a beep, a beep, a beep"). The number of alarm sound signals to be stored may be two or more, and the forms of synthesized speech and electronic sound may be other than the above.

  When the calculation means 13 determines that the detection means 11 has continuously detected the detected gas concentration equal to or higher than the alarm level, the alarm means 15 receives the alarm signal S1 from the calculation means 13 and selects the selected alarm sound signal. A warning is issued by voice based on In this embodiment, the alarm means 15 is composed of a speaker and its drive circuit, and converts the alarm sound signal S2 into an alarm sound S3 and outputs it.

  The remote control device 20 includes an operation means 21 for receiving an operation, a remote control side communication means 22 capable of communicating with the alarm device main bodies 10a and 10b, and a remote control side storage for storing an identifier signal ID received from the alarm device main body 10 (for example, 10a).

  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. Further, the remote control device 20 may be configured to be detachable from the alarm device body 10.

  As long as the operation means 21 is a mode that serves as a trigger for executing the edge processing, any operation means 21 may be used, for example, a switch-like member. At the time of operation, the operation means 21 may be operated in an arbitrary manner such as long press, short press or continuous press. For example, the operation means 21 may be switched in the same manner for each of the two alarm device bodies 10a and 10b, or may be switched in a different manner. When the switch operation is performed in a different manner, for example, the operation means 21 is long-pressed on the alarm main body 10a, and the operation means 21 is continuously pressed on the alarm main body 10a. At this time, what is necessary is just to be able to identify which operation is performed with respect to each in each of the alarm device main bodies 10a and 10b.

  Further, a plurality of operation means 21 may be formed so that each operation means performs a different operation. For example, when two operating means 21 are provided, it is possible to use a switch that performs edge processing on one side and a switch that performs normal processing (for example, inspection processing) different from the edge processing on the other side.

The remote control side communication means 22 may be configured to be able to communicate with the remote control device 20 by wireless communication or the like, and the communication method is not limited, but the wireless communication is preferably bidirectional communication. In the present embodiment, a case where infrared communication is applied as the remote control side communication unit 22 will be described. That is, the remote control side communication means 22 can be configured by an infrared transmission / reception unit.
The remote control side communication means 22 can be configured to change the intensity and frequency of radio waves during transmission and reception. Thereby, when the accuracy of communication with the alarm device body 10 is low, the strength and frequency of radio waves can be changed to improve the accuracy of communication with the alarm device body 10.
The change in the intensity and frequency of the radio wave may be configured to be changed stepwise automatically when the communication accuracy is low, or may be changed by performing a predetermined operation on the operation means 21 of the remote control device 20. . When the intensity and frequency of radio waves are changed in stages automatically, a known technique such as determining that communication accuracy is low based on the frequency at which communication is interrupted within a predetermined period, the interval between communications, etc. Can be used.
Moreover, when changing the intensity | strength and frequency of an electromagnetic wave, you may notify that that from the alarm means 15 of the alarm main body 10 beforehand.

  The remote control side storage means 23 may be in any form as long as it is a memory or storage that stores the identifier signal ID received from the alarm device body 10.

  The remote control side control means 24 may use a microcomputer or the like that can perform control to transmit the identifier signal ID received and stored in the remote control side storage means 23 to the alarm device body 10.

The remote control device 20 may be provided with display means (not shown) for displaying the operation status of the remote control device 20. For example, the display unit may display a matching process, a normal process, or the like, or may display the alarm status of the alarm device body 10. The display of the margin process can be, for example, the received identifier signal ID or the content for reporting the completion of the margin process.
Further, in place of the display means, alarm means may be provided in the remote control device 20 so that the contents displayed on the display means can be notified by voice.

Further, the main body side control means 16 for transmitting the identifier signal ID to the remote control device 20 operated by the operation means 21 and confirming whether or not it has information on the identifier signal ID received from the remote control device 20 is provided with an alarm device. The main bodies 10a and 10b are provided.

  The main body side control means 16 determines whether or not it can be connected to another alarm device body 10 (for example, 10b) based on the received identifier signal ID, and based on the determination result, the other alarm device body 10 (for example, 10b). ) And match processing.

  On the other hand, the remote control device 20 can also cancel the border of the plurality of alarm main bodies 10 that have undergone the border processing. That is, this release process can also be executed by operating the operating means 21. In this case, the border processing and the release processing may be switched by different modes (long press operation, continuous press operation, etc.), or a plurality of operation means 21 may be formed to perform different operations in each processing. The means 21 may be operated.

  Hereinafter, a method of performing the edge processing of the two alarm device bodies 10a and 10b by the remote control device 20 will be described. By assembling these alarm devices 10a and 10b, mutual information can be shared.

  First, the operation means 21 of the remote control device 20 is pressed for a long time to the alarm device main body 10a, and the identifier signal IDa is received from the alarm device main body 10a. The received identifier signal IDa is stored in the remote control side storage means 23.

  Next, the operation means 21 of the remote control device 20 is continuously pushed to the alarm main body 10b, and the identifier signal IDa received and stored in the remote control side storage means 23 is transmitted to the alarm main body 10b.

The alarm main body 10b that has received the identifier signal IDa checks whether the main body side control means 16 has information relating to the identifier signal IDa.

  The main body side control means 16 in the alarm device main body 10b determines whether or not the alarm device main body 10a can be assembled based on the received identifier signal IDa.

  For example, the alarm device main body 10b that has received the identifier signal IDa stores the identifier signal IDa, and the alarm device main body 10a transmits the identifier signal IDa to the remote control device 20 and, after a predetermined time has elapsed, outputs a signal for the association. It transmits to the alarm device body 10b. The alarm device body 10b that has received the signal confirms whether or not it has information relating to the identifier signal IDa of the transmission source alarm device body 10a.

  In the margin processing, for example, frequency identification or the like may be controlled so that the main body side communication means 12 in the alarm main body 10a and the alarm main body 10b can always communicate with each other.

  In the process of assembling the alarm device main bodies 10a and 10b, the operation means 21 of the remote control device 20 may be first operated on the alarm device main body 10b to receive the identifier signal IDb from the alarm device main body 10b. . In this case, the remote controller 20 transmits the identifier signal IDb to the alarm device main body 10a, and the main body side control means 16 in the alarm device main body 10a determines whether or not the alarm device main body 10b can be connected based on the received identifier signal IDb. To do.

  In the alarm system X of the present invention, when a plurality of alarm device bodies 10 are subjected to the margin processing, the remote controller 20 can transmit and receive each other's identifiers. Accordingly, even after a plurality of alarm device bodies 10 have already been installed at predetermined distances, the respective alarm device bodies 10 and the remote control devices are carried by carrying the remote control device 20 as a separate body from the alarm device body 10. 20 can be easily communicated with each other, so that the plurality of alarm main bodies 10 can be easily assembled by relaying them by the remote control device 20.

  In order to cancel the border processing of the alarm device main bodies 10a and 10b, the remote control device 20 is controlled so as to interrupt communication between the main body side communication means 12 in the alarm device main body 10a and the main body side communication means 12 in the alarm device main body 10b. do it.

  The operation of the remote control device at the time of releasing the frame may be executed by performing an operation different from that at the time of the frame operation when there is one operation unit 21, or a plurality of operation units 21 are formed. In this case, it is only necessary to assign operation means for edge setting and edge release.

[Another embodiment 1]
In the above-described embodiment, the main body storage unit 14 may store the edge information.

  As the match information, for example, information such as identification numbers of all alarm device bodies 10 that can be matched can be used. That is, by setting a plurality of identifiers, it is possible to set a plurality of alarm device bodies 10 that are to be targeted by the matching information.

  In this case, when performing the matching processing of the alarm device main bodies 10a and 10b, the operation means 21 of the remote control device 20 is operated with respect to the alarm device main body 10a to receive the identifier signal IDa from the alarm device main body 10a. By transmitting the identifier signal IDa to the alarm device main body 10b, the main body side control means 16 in the alarm device main body 10b determines whether or not the alarm device main body 10a can be connected based on the received identifier signal IDa. This determination is made by determining whether or not the identifier signal IDa is included in the association information stored in the main body side storage unit 14 in advance.

  If the identifier information IDa is included in the margin information, the main body side control means 16 performs margin processing on the alarm device main body 10b and the alarm device main body 10a.

In order to cancel the border processing of the alarm device main bodies 10a and 10b in this embodiment, a processing for changing or deleting the border information stored in the main body side storage means 14 in the alarm device main bodies 10a and 10b may be performed.
At this time, for example, by operating the operation means 21 of the remote control device 20 toward the alarm main body 10a, the margin information stored in the main body side storage means 14 of the alarm main body 10a is changed or deleted. Thereby, the main body side control means 16 of the alarm main body 10a may be controlled so that the main body side communication means 12 in the alarm main body 10a interrupts communication with the main body side communication means 12 in the alarm main body 10b.

[Another embodiment 2]
In the above-described embodiment, when a plurality of identifier signals are stored in the remote-control-side storage unit 23 of the remote-control device 21 and the identifier signals are transmitted to a predetermined alarm device main body, all the stored in the remote-control-side storage unit 23 are stored. The identifier may be transmitted, or only a part of the identifier may be transmitted. For example, when the remote control device 21 has a plurality of operation means 21, it is possible to transmit only a desired identifier signal by storing each operation means in association with each identifier signal. When there is only one operation means 21, the operation mode of the operation means 21 and each identifier signal may be stored in association with each other. By doing in this way, desired alarm device bodies can be subjected to edge processing and edge release processing.

[Another embodiment 3]
In the above-described embodiment, the edge level may be stored together with the identifier information so that edges having different edge levels can be created. For example, when there are a plurality of alarm levels in a stepwise manner, even if an alarm level 1 gas is detected, the alarm is not notified at the end of the alarm. It is conceivable to do so. By doing in this way, even if the use situation of the room changes after the alarm system X is installed, the alarm mode according to the use situation can be provided.
