Description

  The present invention relates to an improvement of an alarm system in which each alarm device outputs an alarm when it detects the occurrence of a predetermined event, and outputs an alarm in conjunction with the other alarm devices by wireless communication.

  In recent years, it consists of alarm devices that communicate with each other wirelessly, and when one alarm device detects the occurrence of a predetermined event, it outputs an alarm by itself and also outputs the alarm in conjunction with notifying other alarm devices by wireless communication. Such an alarm system has been developed.

As an example of such an alarm system, for example, the following Patent Document 1 discloses a fire alarm system including a fire alarm device that can suppress power consumption while preventing oversight of a radio signal transmitted from another fire alarm device. Proposed.
JP2008-004033

However, even in a system comprising alarm devices that communicate wirelessly with each other as described above, it is necessary to operate each alarm device one at a time during periodic inspections. There was a problem that it took.
An object of the present invention is to provide a system that can solve the problem and can test all alarm devices with a simple operation.

  In order to solve the above problems, the present invention comprises a plurality of wireless devices that communicate wirelessly with each other, and each wireless device outputs an alarm when it detects the occurrence of a predetermined event, and the occurrence of an event in another device by wireless communication. In the radio system in which the alarm is output in conjunction with the notification, the master radio unit performs the test operation with the test unit, the operation unit, the notification unit, and the operation unit for executing a function test as self-diagnosis. And when the test request signal is received, the test unit causes a self-diagnosis to be executed and the test result is notified and output by the notification unit, and the control unit is configured to transmit a test command signal. When the slave radio receives a test operation at the test unit, the operation unit, the notification unit, and the operation unit that performs a function test as a self-diagnosis, the test request signal The test unit performs self-diagnosis, and the test unit notifies and outputs the test result. When the test command signal is received, the test unit does not transmit the test request signal, and the test unit performs self-diagnosis. And a control unit that causes the notification unit to notify and output the test result.

  In addition, the parent radio device includes a storage unit that registers the identification information of the child radio device, and the child radio device transmits a response signal including the identification information of the own device to the test command signal. The master radio device does not transmit the response signal by identifying the child radio device of the transmission source when receiving the response signal until a predetermined time elapses after transmitting the test command signal. You may make it investigate the presence or absence of a sub radio | wireless machine, and output the alerting | reporting result.

  The master radio further includes a storage unit in which the identification information of the slave radio is registered. The slave radio includes the identification information of the own device and the test result with respect to the test command signal. When the response signal is received before the predetermined time elapses after the test command signal is transmitted, the master radio device identifies the child radio device of the transmission source and discriminates the test result. By doing so, the presence / absence of a slave radio device having a malfunction may be investigated, and the result of the investigation may be notified and output.

  Further, the master radio device transmits a notification command signal after the predetermined time has elapsed, and the slave radio device outputs the test result after receiving the notification command signal. Good.

  In addition, if there is a slave radio that has not transmitted the response signal, the master radio may notify and output the slave radio as a communication abnormality.

  In addition, if there is a slave radio having the malfunction, the radio master radio may output the slave radio as a malfunction.

  According to the present invention, the self-diagnosis is performed not only on the master radio but also on all slave radios only by performing a test operation on either the master radio or the slave radio. Inspection can be done easily.

  Further, the slave radio transmits a response signal including identification information of the own machine to the test command signal, and the master radio specifies the source slave radio when receiving the response signal, In the configuration in which the presence / absence of a slave radio device that has not transmitted a response signal is investigated and the result of the investigation is notified, only the test operation is performed in the master radio device 1, and the registered slave radio device 2 can be connected. You can perform a radio wave confirmation test.

  In response to the test command signal, the slave radio transmits a response signal including its own identification information and the test result. When the master radio receives the response signal, the slave radio transmits the slave radio of the transmission source. By identifying the test results and identifying the presence / absence of a slave radio having a malfunction, and informing the investigation result, if even one slave radio has a malfunction, the master radio It can be known from the notification output. In other words, it is not necessary to look at each child radio unit one by one.

  In the configuration in which the master radio transmits a notification command signal, and the slave radio receives the notification command signal and then outputs the test result, the timing at which the slave radio transmits the notification output can be adjusted. This makes it easier to hear the notification output.

  In addition, if there is a slave radio device that has not transmitted a response signal, the master radio device can easily know which slave radio device has a communication error in the configuration in which the slave radio device is notified and output as a communication error. This makes it easy to install the radio system and confirm the test after installation.

  In addition, if there is a slave radio having a malfunction, the radio master radio is informed that the slave radio has a malfunction. Which slave radio has a malfunction due to the notification output of the master radio Because it is possible to know easily, it becomes possible to deal with it quickly.

  The present invention comprises a plurality of wireless devices that communicate with each other wirelessly. Each wireless device monitors the occurrence of a predetermined event, outputs an alarm when the occurrence of the event is detected, and notifies other devices by wireless communication. It is applied to a radio system etc. that is configured to output an alarm in conjunction with Possible events include fire factors such as smoke and heat, and illegal entry of outsiders into the house.

  FIG. 1 is a block diagram illustrating a schematic configuration of a radio that constitutes an embodiment of the present invention. This embodiment is a fire alarm system, and includes a master radio device 1 and a plurality of slave radio devices 2 as a fire alarm device.

  Here, the master wireless device 1 has an antenna 11a and wirelessly communicates with other wireless devices, a sensor (not shown), a detection unit 12 that monitors a fire factor, and a function test as a self-diagnosis. Are provided with a test unit 13, an operation unit 14, a notification unit 15 that outputs a fire alarm by buzzer sound or voice, a control unit 16A that controls these components, and a storage unit 17. The operation unit 14 includes operation buttons (not shown) for receiving a stop operation for stopping the alarm output, a test operation for executing a self-diagnosis described later, and the like. These buttons may be independent or combined. Although the power supply is not shown, a power supply circuit corresponding to a commercial power supply may be provided or a battery power supply may be used.

  Test contents of the test unit 13 include, for example, a battery power supply voltage level test, a sensor sensitivity test, a disconnection test, and an alarm output test using a pseudo signal, but the test contents are not particularly limited.

  The configuration of the slave radio device 2 is almost the same as that of the master radio device 1, but the basic operation differs between the master radio device 1 and the slave radio device 2 as described below.

  That is, when the detection unit 12 detects a fire occurrence, the master wireless device 1 outputs a warning by driving a speaker included in the notification unit 15 to sound an alarm sound at a predetermined period (for example, every 4 seconds), and In order to output alarms in conjunction with all the slave radio devices 2, an interlock command signal is transmitted from the transmission / reception unit 2. If the notification signal transmitted when the slave radio 2 detects the occurrence of a fire is received, an alarm is output in conjunction with the slave radio 2 and the slave radio 2 other than the slave radio 2 that has transmitted the notification signal is also interlocked. In order to output an alarm, an interlock command signal is transmitted.

  On the other hand, when the detection unit 12 detects the occurrence of a fire, the slave radio device 2 outputs a warning by driving a speaker included in the notification unit 15 to sound an alarm sound at a predetermined period, and further to the master radio device 1. A notification signal is transmitted from the communication unit 11 to notify that the occurrence of fire has been detected. Further, when a interlock command signal is received from the master radio device 1 or another slave radio device 2, an alarm is output in conjunction with the command signal.

  The radio communication format of the master radio device 1 and the slave radio device 2 is not particularly limited, and a polling format using identification information, a format in which the master radio device 1 assigns a time slot to each of the slave radio devices 2, and the like are possible. . It is necessary to prevent interference with other radio system by using a house code or selecting a channel to be used from a plurality of communication channels.

  The reception of the alarm output stop operation in the operation unit 14 can also be processed as an occurrence of an event in the same manner as in the case of the fire occurrence. In this case, if the notification output stop operation is accepted in either the master radio device 1 or the slave radio device 2, the other devices also stop the notification output for a predetermined time in conjunction with the operation.

  Further, since the master radio device 1 has a function of transmitting an interlocking command signal when receiving the notification signal transmitted by the slave radio device 2, this radio system is centered on the master radio device 1 and has a child radio signal around it. By disposing the machine 2, it is possible to cover a wider range.

FIG. 2 is an arrangement example of the master radio device 1 and the slave radio device 2 for explaining this.
In this arrangement example, all the child radio devices 2 exist in the wireless communication possible range S1 of the parent radio device 1 arranged in the center. In addition, the master radio device 1 and the slave radio device 2 # 2 exist in the wireless communication possible range S2 # 1 of the child radio device 2 # 1, and the radio communication possible range S2 # 2 of the child radio device 2 # 2 A master radio device 1 and a slave radio device 2 # 1 exist, and each of a radio communication possible range S2 # 3 of the slave radio device 2 # 3 and a radio communication possible range S2 # 4 of the slave radio device 2 # 4 There is only the parent radio 1. Therefore, although the master radio device 1 can communicate with all the slave radio devices 2, the slave radio device 2 # 1 is the master radio device 1 and the slave radio device 2 # 2, and the slave radio device 2 # 2 is the master radio device. 1 and the slave radio devices 2 # 1 and the slave radio devices 2 # 3 and 2 # 4 can communicate with only the master radio device 1.

  Even when remote radio devices 2 that are far away cannot communicate with each other as in this arrangement example, the master radio device 1 receives a notification signal and transmits an interlocking command signal, so that all the sub radio devices 2 receive an alarm. Sound can be sounded. In addition, if the slave radio 2 is configured to sound an alarm sound not only by the interlock command signal but also by a notification signal transmitted by another slave radio 2, it is possible that the master radio 1 is out of order. Even in this case, at least the slave radio device 2 that has detected a fire and the slave radio device 2 within the possible range of the radio communication of the slave radio device 2 can make an alarm sound.

Next, features of the present invention will be described. The radio system according to the present invention has a self-diagnosis function for each radio, and can perform self-diagnosis on all radios only by a test operation of either the master radio 1 or the slave radio 2. There is a feature.
Therefore, the control unit 16A of the master radio device 1 receives the test operation signal from its own operation unit or receives a test request signal transmitted from any of the slave radio devices 2, by the test unit 13. The self-diagnosis is executed and the test result is notified and output by the notification unit 15 and a test command signal is transmitted.
On the other hand, the control unit 16B of the slave radio device 2 transmits a test request signal when a test operation is accepted by the operation unit, and causes the test unit 13 to execute a self-diagnosis and notify the test unit 15 of the test result. When the test command signal is received, the test request signal is not transmitted, the test unit 13 performs a self-diagnosis, and the test unit 15 notifies and outputs the test result.
The notification output from the master radio device 1 and the slave radio device 2 is given by a predetermined sound such as “normal” or “failed (battery is dead)”. A liquid crystal panel or the like may be provided and displayed there.

FIG. 3 is a flowchart for explaining the operation of the self-diagnosis. The process of the master radio device 1 (steps 101 and 102), the process of the slave radio device 2 # 1 (steps 201 to 203), and the slave radio device 2 # 2 (Steps 301 and 302) are shown in time series.
In this example, first, the sub-radio device 2 # 1 detects that the test button is pressed on the operation unit, and transmits a test request signal (step 201). The master wireless device 1 receives the test request signal, performs self-diagnosis, transmits a test command signal, and outputs a test result (steps 101 and 102). Then, the slave radio device 2 # 1 and the slave radio device 2 # 2 receive the test command signal, perform self-diagnosis, and output a test result (steps 202, 203, 301, and 302). Note that the slave radio device 2 whose test button is pressed may notify the self-diagnosis and the test result before receiving the test command signal from the master radio device 1.

  With such a configuration, it is possible to test all the radios of the radio system by simply performing a test operation on either the parent radio 1 or the slave radio 2.

  Further, the master radio device 1 registers the identification information of the slave radio device 2 in the storage unit 17 in advance, and the slave radio device 2 sends a response signal including the identification information of the own device to the test command signal. When the master wireless device 1 receives the response signal until a predetermined time has elapsed after transmitting the test command signal, the master wireless device 1 identifies the child wireless device 2 as a transmission source based on the identification information, thereby It is possible to investigate the presence / absence of the sub-radio device 2 that is not transmitting and notify the survey result. Here, if all of the slave radio devices are transmitting response signals, the master radio device 1 outputs a sound such as “normal”, but if the slave radio device 2 not transmitting the response signal If there is, a voice message such as “Cannot communicate with the slave unit” is output. With such a configuration, it is possible to perform a radio wave arrival confirmation test with the registered slave radio device 2 simply by listening to the test result at the master radio device 1.

  As a modified example, if there is a slave radio 2 that has not transmitted a response signal, the master radio 1 may notify and output the slave radio 2 as a communication abnormality. That is, the master radio device 1 outputs a sound such as “cannot communicate with the slave device of number 2”. Then, since it is possible to easily know which child radio device 2 is in communication abnormality, the installation of the radio device system becomes easy.

  The master radio device 1 registers the identification information of the slave radio device 2 in the storage unit 17 in advance, and the slave radio device 2 receives the identification information of the own device and the test result in response to the test command signal. When the response signal is received until the predetermined time elapses after the test command signal is transmitted, the master wireless device 1 specifies the transmission source slave wireless device 2 based on the identification information. By determining the test result, the presence / absence of the slave radio device 2 having a function abnormality or a battery voltage abnormality may be investigated, and the investigation result may be notified. Here, if the functions of the master radio device 1 and all the slave radio devices 2 are normal, the master radio device 1 reports and outputs a sound such as “normal”. For example, one of the slave radio devices 2 functions. If it is abnormal, a voice message such as “Slave unit is faulty (slave unit battery is dead)” is output. With such a configuration, when there is a function abnormality or battery voltage abnormality even in one of the slave wireless devices 2, it can be known from the notification output of the parent wireless device 1. In other words, it is not necessary to look around the slave radio devices 2 one by one.

  As a modified example, if there is a slave radio 2 that has not transmitted a response signal, the master radio 1 may notify and output the slave radio 2 as a communication abnormality. That is, the master radio device 1 outputs a sound such as “No. 2 slave unit is out of order (the battery of the No. 2 slave unit has a lifetime)”. By doing so, it is possible to easily know which child radio device 2 is out of order or abnormal battery voltage from the notification output of the parent radio device 1, and thus it is possible to deal with it quickly.

FIG. 4 is a flowchart for explaining the operation of the self-diagnosis. The process of the master radio device 1 (steps 103 and 104), the process of the slave radio device 2 # 1 (steps 204 to 206), and the slave radio device 2 # 2 (Steps 303 and 304) are shown in time series.
In this example, first, the sub-radio device 2 # 1 detects that the test button is pressed on the operation unit, and transmits a test request signal (step 204). The master wireless device 1 receives the test request signal, performs self-diagnosis, and transmits a test command signal (step 103). The slave radio device 2 # 1 and the slave radio device 2 # 2 receive the test command signal, perform self-diagnosis, and transmit a response signal including the identification information of the own device and the test result. The test result is reported and output (steps 205, 206, 303, 304). Thereafter, the master radio 1 receives the response signals transmitted from the slave radio 2 # 1 and the slave radio 2 # 2 and discriminates the test result, thereby detecting a slave radio having a function abnormality or battery voltage abnormality. The presence / absence of the machine 2 is investigated, and the examination result is notified together with the test result of the own machine (step 104).

  In each of the above-described configurations, the master radio device 1 transmits a notification command signal after the predetermined time has elapsed, and the slave radio device 2 outputs a test result after receiving the notification command signal. You may do it. In this way, since the timing at which the slave radio device 2 outputs the notification can be made uniform, the notification output can be easily heard.

FIG. 5 is a flowchart for explaining the operation of the self-diagnosis. The processing of the master radio device 1 (steps 105 and 106), the processing of the slave radio device 2 # 1 (steps 207 to 209), and the slave radio device 2 # 2 (Steps 305 and 306) are shown in time series.
In this example, first, the sub-radio device 2 # 1 detects that the test button is pressed on the operation unit, and transmits a test request signal (step 207). The master wireless device 1 receives the test request signal, performs self-diagnosis, and transmits a test command signal (step 105). The slave radio device 2 # 1 and the slave radio device 2 # 2 receive the test command signal, execute self-diagnosis, and transmit a response signal including the identification information of the own device and the test result (step). 208, 305). Thereafter, the master radio device 1 confirms that both the response signal transmitted by the slave radio device 2 # 1 and the response signal transmitted by the slave radio device 2 # 2 are received, and then transmits a notification command signal. Furthermore, the investigation result is notified together with the test result of the own machine (step 106). The slave radio 2 # 1 and the slave radio 2 # 2 receive the notification command signal and simultaneously output the test result (steps 209 and 306).
