The “test process” is a process related to a test, and specifically, a process related to a supply test. The timing for executing this test process is arbitrary. For example, when the power of the disaster prevention system 100 and the test device 3 is turned on, the receiver 1 is subjected to a predetermined operation performed via the operation unit 12 of the receiver 1. The test process will be described from the point where the test process is started, assuming that the operation mode, which is the mode for operating the above, is started and executed after switching from the normal monitoring mode to the test mode and setting the test mode. Here, the "normal monitoring mode" is a mode that is normally set to monitor the monitoring area, and specifically, is a mode that transfers a report to the outside when an abnormality in the monitoring area is detected. be. Further, the "test mode" is a mode set at the time of inspection for testing the disaster prevention system 100, and specifically, a mode in which an abnormality in the monitoring area is not transferred to the outside when an abnormality is detected.

In addition, a case where an operation test (sensitivity test) is performed in the test process will be described. Here, the "operation test" is a supply test, and refers to at least the normality of the functions of the physical quantity detection unit 22 or the abnormality detection unit 262 of the sensor 2 with respect to the detection target supplied to the periphery of the sensor 2. Specifically, it is a test for determining that the sensor 2 has detected a fire within a predetermined determination time (for example, 1 minute or the like) from the time when the smoke supply is started.

First, as shown in FIG. 4, in SA1, the control unit 37 of the test apparatus 3 determines whether or not to start the test. Specifically, it monitors whether or not the “test start button” (not shown) of the operation unit 32 of the test device 3 of FIG. 1 is operated, and determines based on the monitoring result. Then, when the "test start button" is not operated, it is determined that the test is not started (NO of SA1), and SA1 is repeatedly executed until it is determined that the test is started. Further, when the "test start button" is operated, it is determined that the test is started (YES of SA1), and the process proceeds to SA2. Here, for example, as shown in FIG. 2, a “test start button” (not shown) is pressed while the user holds the test device 3 so that the sensor 2 is housed in the storage unit 301 of the test device 3. The case of pressing and operating will be referred to as "exemplary case" and will be described below. In the case of this example, it is determined that the test is started in SA1 of FIG.

Next, in SA2, the control unit 37 of the test device 3 supplies the detection target of the sensor 2 to the sensor 2. Specifically, a predetermined amount of smoke is output from a gas can which is a smoke generator (not shown) in the supply unit 34 of FIG. The amount of smoke here is arbitrary as long as it is an amount that detects a fire when the sensor 2 is operating normally, that is, for example, in the accommodating portion 301 and the installation surface W1 in FIG. It is assumed that the concentration of smoke in the enclosed space is set to be higher than the fire determination threshold value of the storage unit 25 of the sensor 2 of FIG. Here, in the example, "10 (% / m)" is stored as the fire determination threshold value of the storage unit 25 of the sensor 2, and the output smoke is output by outputting smoke from the gas can with SA2. Will be supplied to the inside of the accommodating portion 301 via the flow path F1 of FIG. 3, and the concentration of smoke around the sensor 2 will increase to "12 (% / m)", which will be described below. ..

Returning to FIG. 4, in SA3, the control unit 37 of the test apparatus 3 transmits a test start signal. Specifically, the test start signal is wirelessly transmitted to the sensor 2 via the antenna 311 of the test device 3 of FIG. 3 without passing through the receiver 1 of FIG. Here, in the example, the test start signal is wirelessly transmitted to the sensor 2 via the antenna 311 of the test device 3. The test start signal here shall be transmitted so that the propagation distance is extremely short (for example, several centimeters). Then, since the propagation distance is extremely short, the test start signal is wirelessly transmitted to a sensor other than the sensor 2 (that is, a sensor that is not the subject of the test) against the intention of the user. Can be prevented.

Returning to FIG. 4, on the other hand, in SB1, the test unit 261 of the sensor 2 determines whether or not to start the test. Specifically, the communication unit 21 of FIG. 1 is monitored to determine whether or not the test start signal from the test device 3 has been received wirelessly, and whether or not to start the test based on the determination result is determined. judge. Then, if it is not determined that the test start signal from the test apparatus 3 is received wirelessly, it is determined that the test is not started (NO of SB1), and SB1 is repeatedly repeated until it is determined that the test is started. Execute. Further, when it is determined that the test start signal from the test apparatus 3 is received wirelessly, it is determined that the test is to be started (YES of SB1), and the process proceeds to SB2. Here, in the example, since the test start signal from the test device 3 is received wirelessly, it is determined that the test is started.

Returning to FIG. 4, the test unit 261 of the sensor 2 performs the test in SB2. Specifically, an operation test is performed as a supply test. More specifically, the sensor 2 in FIG. 1 is provided with a time measuring means such as a counter (not shown), and based on the time measuring result of the time measuring means, the test start signal is wirelessly transmitted by SB1 in FIG. The following determination is performed on the assumption that the elapsed time from the time determined to be received (hereinafter, time T1) to the current time (hereinafter, time T2) can be specified.

Specifically, the abnormality detection unit 262 performs a process of detecting a fire in the monitoring area based on the detection result of the physical quantity detection unit 22 according to a command from the test unit 261 of the sensor 2 from time T1 to time T2. Is repeated every predetermined measurement time (the predetermined measurement time is shorter than the predetermined determination time, for example, 5 seconds, etc.) until the elapsed time of the above exceeds the predetermined determination time. More specifically, acquiring the smoke concentration which is the detection result of the physical quantity detection unit 22 (hereinafter, acquisition step), and comparing the acquired smoke concentration with the fire determination threshold of the storage unit 25 (hereinafter, comparison). Step) and, based on the comparison result, it is determined whether or not the acquired smoke concentration exceeds the fire determination threshold (hereinafter referred to as the determination step). Repeat every predetermined measurement time until the time is exceeded.

Here, in the example, it is assumed that "10.1 (% / m)" is acquired in the "acquisition step" before the elapsed time from the time T1 to the time T2 exceeds the predetermined determination time. In this case, in the "determination step", it is determined that the detection result "10.1 (% / m)" of the physical quantity detection unit 22 exceeds the fire determination threshold value "10 (% / m)". ..

Returning to FIG. 4, the test unit 261 of the sensor 2 in SB3 outputs the test result. Specifically, based on the test result of SB2, the test result signal is transmitted to the receiver 1 and the test device 3 of FIG. 1, and the lighting control of the indicator lamp 231 of the sensor 2 of FIG. 3 is performed.

First, regarding the transmission of the test result signal, specifically, in SB2 of FIG. 4, the concentration of smoke is increased in the “judgment step” of SB2 by the time the elapsed time from time T1 to time T2 exceeds a predetermined determination time. When it is determined that the fire judgment threshold is exceeded, "good", which is a test result indicating that the operation is normal, is specified as a fire detected, while in SB2, from time T1 to time T2. If it is not determined in the "judgment step" of SB2 that the smoke concentration exceeds the fire judgment threshold by the time when the elapsed time exceeds the predetermined judgment time, it is assumed that the fire has not been detected. Specify "No" as a test result indicating that is not normal. Next, the sensor ID of the storage unit 25 of FIG. 1 is acquired, and a test result signal including at least the acquired sensor ID and the specified test result is generated. When the above-mentioned identified test result is "good", it is determined that the test result signal exceeds the fire judgment threshold in the "judgment step" of SB2 in addition to the sensor ID and the test result. Smoke concentration shall also be specified and generated including the specified smoke concentration. Next, the generated test result signal is transmitted to the receiver 1 and the test device 3 via the communication unit 21 of FIG.

Here, in the example, “10.1 (% / m)”, which is the detection result of the physical quantity detection unit 22 acquired during the time elapsed from the time T1 to the time T2 exceeds the predetermined determination time, is Since it was determined that the fire judgment threshold value "10 (% / m)" was exceeded, "good" was specified as the test result, and "ID2" was acquired as the sensor ID, and in SB2. The concentration of smoke determined to exceed the fire determination threshold, "10.1 (% / m)", is specified. Then, a test result signal including these "ID2", "good", and "10.1 (% / m)" is generated, and the generated test result signal is used for the communication unit 21 and the communication line L1 in FIG. The test result signal is transmitted to the receiver 1 by wire via a wire, and the generated test result signal is wirelessly transmitted to the test device 3 via an antenna (not shown) of the communication unit 21.

Further, specifically, regarding the lighting control of the indicator lamp 231 of FIG. 3, in SB2 of FIG. 4, in the "determination step" of SB2 until the elapsed time from the time T1 to the time T2 exceeds the predetermined determination time. When it is determined that the concentration of smoke exceeds the fire determination threshold, it is considered that a fire has been detected, and in order to indicate that the operation is normal, the display or the like 231 is displayed for a predetermined lighting time (for example, 10 to 15 seconds). Etc.), while in SB2 of FIG. 4, the smoke concentration exceeds the fire judgment threshold in the "judgment step" of SB2 by the time the elapsed time from time T1 to time T2 exceeds the predetermined judgment time. If it is not determined that the fire is on, it is assumed that the fire has not been detected, and the indicator light 231 is left off.

Here, in the example, “10.1 (% / m)”, which is the detection result of the physical quantity detection unit 22 acquired during the time elapsed from the time T1 to the time T2 exceeds the predetermined determination time, is Since it is determined that the fire determination threshold value of "10 (% / m)" is exceeded, the display or the like 231 is lit for a predetermined lighting time.

Specifically, the test result signal transmitted by wire in SB3 is received via the communication unit 11 of the receiver 1. Here, in the example, the test result signal including "ID2", "good", and "10.1 (% / m)" is received.

Next, in SC2, the control unit 16 of the receiver 1 stores the information. Specifically, the information included in the test result signal received by the SC1 is acquired, and the acquired information is stored in the storage unit 15 of FIG. 1 in a state of being associated with each other. Here, in the example, "ID2", "good", and "10.1 (% / m)" are acquired and stored.

Returning to FIG. 4, in SC3, the control unit 16 of the receiver 1 determines whether or not to output the test result. Specifically, the operation unit 12 of the receiver 1 of FIG. 1 is monitored, and it is determined whether or not the result output request operation input, which is the operation input for requesting the output of the test result, has been input, and the determination result. It is determined whether or not to output the test result based on. Then, when it is determined that the result output request operation input has not been input, it is determined that the test result is not output (NO of SC3), and SC3 is repeatedly executed until it is determined that the test result is output. do. Further, when it is determined that the result output request operation input has been input, it is determined that the test result is output (YES of SC3), and the process proceeds to SC4. Here, in the example, it is assumed that the user inputs the result output request operation input via the operation unit 12 of the receiver 1. In this case, it is determined that the test result is output.

Returning to FIG. 4, the control unit 16 of the receiver 1 outputs the test result in the SC4. The output of this test result can be performed by using an arbitrary method, but here, for example, the information stored in the SC2 is displayed and output via the display unit 13, and the acoustic unit 14 is displayed.

Here, in the example, the installation is information in which the sensor ID “ID2” of the sensor 2 in FIG. 1 and the “room A on the first floor” where the sensor 2 is installed are associated with each other. The location information will be described below assuming that the location information is stored in the storage unit 15 of the receiver 1. In this case, first, "installation location information" and "ID2" stored in SC2 are acquired from the storage unit 15, and based on the acquired information, "1" is set as the installation location of the sensor 2 specified by "ID2". Identify "Room A" on the floor. Next, "good" and "10.1 (% / m)" stored in SC2 are acquired, and the following processing is performed based on the above-mentioned specific result and this acquisition result. Specifically, for the "sensor in room A on the first floor", the test result is "good" and the smoke concentration detected by the sensor 2 at the time of issuance is "10.1 (% / m)". Is associated with and output as text information via the display unit 13, or "The operation of the sensor in room A on the first floor is normal, and 10.1 (% / m) of smoke is detected and emitted. A voice message such as "I have reported" is output from the sound unit 14.

Returning to FIG. 4, on the other hand, in SA4, the control unit 37 of the test apparatus 3 receives the test result signal. Specifically, the test result signal transmitted wirelessly in SB3 is wirelessly received via the antenna 311 of FIG. 3 of the test apparatus 3. Here, in the example, the test result signal including "ID2", "good", and "10.1 (% / m)" is received.

Returning to FIG. 4, in SA5, the control unit 37 of the test apparatus 3 acquires the smoke concentration. Specifically, the detection result of the physical quantity detection unit 33 is acquired.

After acquiring the detection result of the detection unit 33, the driving of the light emitting unit 331 and the light receiving unit 332 is terminated. Here, in the example, it is assumed that the detection result of the physical quantity detection unit 33 is "10.13 (% / m)". In this case, "10.13 (% / m)" is acquired as the smoke concentration.

Next, in SA6, the control unit 37 of the test apparatus 3 stores the information. Specifically, in the state where the information contained in the test result signal received by SA4 is acquired, the smoke concentration acquired by SA5 is acquired, and the acquired information is associated with each other, FIG. It is stored in the storage unit 36. Here, in the example, the information contained in the test result signal is "ID2", "good", and "10.1 (% / m)", and the concentration of smoke acquired by SA5 is ". 10.13 (% / m) ”is acquired and stored.

Returning to FIG. 4, in SA7, the control unit 37 of the test apparatus 3 outputs the test result. Any method can be used for the output of this test result, but here, for example, the information stored in the SA6 is displayed and output via the display means of the output unit 35, and the output unit 35 is also output. It is assumed that the audio is output via the audio output means of the above, and the paper is output via the printing means of the output unit 35. Here, in the example, it will be described below assuming that the “installation location information” described in SC4 of FIG. 4 is stored in the storage unit 36 of the test apparatus 3 of FIG. In this case, first, as in the case of SC4, "room A on the first floor" is specified as the installation location of the sensor 2 specified by "ID2".

Although the embodiments according to the present invention have been described above, the specific configuration and means of the present invention may be arbitrarily modified and improved within the scope of the technical idea of each invention described in the claims. Can be done. Hereinafter, such a modification will be described.

(About the problem to be solved and the effect of the invention)
First, the problem to be solved by the invention and the effect of the invention are not limited to the above-mentioned contents, and may differ depending on the implementation environment and the details of the configuration of the invention, and only a part of the above-mentioned problems. Or may produce only some of the effects described above.

(About distribution and integration)
Further, the above-described configuration is a functional concept, and does not necessarily have to be physically configured as shown in the figure. That is, the specific form of dispersion or integration of each part is not limited to the one shown in the drawing, and all or a part thereof can be functionally or physically dispersed or integrated in any unit. The term "system" in the present application is not limited to a system composed of a plurality of devices, but includes a system composed of a single device. Further, the "device" in the present application is not limited to a device composed of a single device, but includes a device composed of a plurality of devices.

(About the test)
Further, the features of the above-described embodiment may be applied to any test other than the test (specifically, the operation test) described in the test process of FIG. Specifically, it may be applied to a non-operation test (sensitivity test) or an automatic test.

Here, the "non-operation test" is the above-mentioned supply test, and is at least the function of the physical quantity detection unit 22 or the abnormality detection unit 262 of the sensor 2 with respect to the detection target supplied to the periphery of the sensor 2. It is a test for normality, and specifically, it is a test for determining that the sensor 2 does not detect a fire within a predetermined determination time (for example, 1 minute or the like) from the time when the smoke supply is started. .. Specifically, when applied to this "non-operation test", SA2 and SB2 in FIG. 4 may be changed as follows. Specifically, in SA2 of FIG. 4, only the amount that does not detect a fire when the sensor 2 is operating normally (that is, the space surrounded by the accommodating portion 301 of FIG. 3 and the installation surface W1). (So that the concentration of smoke is lower than the fire determination threshold value of the sensor 2), the supply unit 34 is made to output smoke, and then the non-operation test is performed by the test unit 261 in SB2 of FIG. If necessary, the processes other than SA2 and SB2 in FIG. 4 may be changed or omitted as appropriate.

The "automatic test" is the above-mentioned non-supply test, which is at least an automatic test for the normality of the physical quantity detection unit 22 or the abnormality detection unit 262 of the sensor 2, and the specific test content is arbitrary. However, here, for example, the following first test or second test may be performed. The "first test" is a test of the physical quantity detection unit 22, and specifically, the detection result of the physical quantity detection unit 22 is repeatedly acquired every predetermined automatic measurement time (for example, 1 second, etc.) and stored in the storage unit. It is stored in 25, and the average value of the above-mentioned stored detection results is repeatedly obtained every predetermined evaluation time (for example, 10 minutes), and the obtained average value is a predetermined zero level (for example, 0 (% / m)) or the like. ) Is a test for confirming whether or not the value deviates from a predetermined value (for example, 0.1 to 0.2 (% / m), etc.). Further, the "second test" is a test of the abnormality detection unit 262, and specifically, the "acquisition step", the "comparison step", and the "comparison step" specifically described in SB2 of FIG. 4 of the embodiment. This is a test for confirming that the determination results in the "determination step" are the same after repeatedly executing the "determination step" a predetermined number of times (for example, 20 times, etc.). Specifically, in the case of applying to this "automatic test", since it is not necessary to supply smoke, it is possible to omit SA2 in FIG. 4 and have the test unit 261 perform the "automatic test" in SB2. good. If necessary, the processes other than SA2 and SB2 in FIG. 4 may be changed or omitted as appropriate. In this configuration, the test unit 261 of the sensor 2 performs an automatic test for normality when the communication unit 21 receives the test start signal, and, for example, transmits the test start signal. Since the sensor 2 can be left unattended later, the user does not have to stay on the sensor 2 side until the end of the test, and the work load on the user can be reduced. Since the test can be performed without the intervention of a worker or the like, it is possible to ensure objectivity and perform an accurate test.

Further, each test described in the above-described embodiment and modification may be selected and executed by the user. Specifically, the operation unit 32 of the test device 3 of FIG. 1 is provided with a test start button for starting each test (for example, an "operation test start button" for starting an operation test, and a non-operation test. "Non-operation test start button" to start, "1st automatic test start button" to start the first test of the automatic test, "2nd automatic test" to start the second test of the automatic test A start button ”) may be provided to transmit a test start signal for starting a test corresponding to each operated test start button when each test start button is operated. Then, the sensor 2 of FIG. 1 is configured to distinguish the tests to be performed based on the test start signal from the test device 3, and then the tests corresponding to the above-described operated test start buttons are performed. You may want to do it. It should be noted that the user may be able to select and execute only an arbitrary test among the tests, instead of all the tests described in the embodiments and modifications.

It is also possible that there is a need to perform a visual test to visually confirm. When the test is performed according to such needs, it is automatically performed on the sensor 2 side (for example, a position where the sensor 2 can be visually recognized in the monitoring area) without operating the receiver 1 (for example, as in Patent Document 1). Since the test can be started, the operator can start the test on the sensor 2 side without going back and forth between the sensor 2 side and the receiver 1 side (for example, the control room where the receiver 1 is installed). The start of the automatic test and the visual test can be performed, and the work efficiency can be improved.

According to the test apparatus described in Appendix 3, when the sensor-side receiving means receives the test start signal, the sensor-side test means performs an automatic test for normality, for example, to obtain a test start signal. Since the sensor can be left unattended after transmission, the user does not have to stay on the sensor side until the end of the test, and the work load on the user can be reduced.

According to the test apparatus described in Appendix 4, by providing the test apparatus side supply means for supplying the detection target of the sensor to the sensor, for example, an environment in which the sensor actually detects an abnormality is simulated. The sensor can be tested.

According to the test apparatus described in Appendix 5, the physical quantity of the detection target is detected and grasped on the test apparatus side, for example, by providing the physical quantity detection means on the test apparatus side for detecting the physical quantity of the detection target around the sensor. It is possible to accurately grasp the result of the sensor test.

According to the test apparatus described in Appendix 6, the receiver is provided with a receiver-side output means for outputting the test results of the test performed by the sensor-side test means, for example, to receive the test results of the sensor. It can be grasped on the side (for example, the management room where the receiver is installed) or on the side of the external device (for example, the management center installed in a remote place) output via the receiver. Therefore, the test result of the sensor can be confirmed at any place or device, and the convenience can be improved.
