Description

  The present invention relates to a test system.

  Conventionally, there is known a disaster prevention system including a sensor that outputs a fire signal when a fire occurrence is detected in a monitoring area, and a receiver that receives the fire signal and notifies the state of the monitoring area. For this disaster prevention system, an operation test for confirming that the disaster prevention system operates normally is periodically performed. In the operation test, for example, at least the work of outputting a fire signal is performed on the sensor side. It takes time and labor to perform the operation test because it requires a plurality of workers including a worker to perform and an operator to confirm the state of the receiver on the receiver side as a test result of the operation test. .

  Therefore, in order to reduce the trouble in performing the operation test, a disaster prevention system that can perform the operation test by, for example, one worker has been proposed (for example, Patent Document 1). The disaster prevention system includes a sensor that outputs a fire signal and a receiver that receives the fire signal. The receiver is connected to a portable terminal carried by an operator when performing an operation test. The communication means for transmitting the fire signal received by the receiver to the portable terminal by performing wireless communication between them. Then, when performing an operation test of this disaster prevention system, the operator performs the work for outputting a fire signal on the sensor side, and then confirms the state of the receiver using the portable terminal on the sensor side. It is carried out.

  However, in the disaster prevention system of Patent Document 1, since it is necessary to modify the receiver so as to perform wireless communication with the mobile terminal, there is a possibility that the test cost for performing the operation test in the disaster prevention system may increase. It was. Further, in this disaster prevention system, in wireless communication performed between the receiver and the portable terminal, for example, interference with other radio waves or radio waves are shielded by a shield such as a wall provided in the monitoring area. In this case, a failure occurs in communication, so that it becomes impossible to transmit a fire signal from the receiver to the portable terminal, and it may be difficult to check the state of the receiver on the sensor side. In such a case, since it is necessary to move from the sensor side to the receiver side to check the state of the receiver, there is a possibility that the effort for performing an operation test in the disaster prevention system may increase.

  This invention was made in view of the said problem, and it aims at providing the test system which can improve the working efficiency which tests the said disaster prevention system while reducing the test cost for testing a disaster prevention system. And

Here, after describing the processing in the disaster prevention system 100 and the processing in the test system 600, the processing in the entire system will be described.

(Processing-Testing process in disaster prevention system)
First, after describing the test process in the disaster prevention system 100, a specific example of this test process will be described.

  FIG. 4 is a flowchart of a test process in the disaster prevention system according to the embodiment (steps are abbreviated as “S” in the description of each process below). This will be described below with reference to FIGS. 1 and 2 as appropriate with reference to FIG. The test process is started when the operation mode of the receiver 4 is switched to the test mode via the switching button 411 after the power switch of the disaster prevention system 100 is turned on.

  First, in SA1, the sensor 1 is in a monitoring state for monitoring the monitoring area, while in SB1, the test unit 462 of the receiver 4 sets the state of the receiver 4 to an initial state.

  Next, in SA2, the sensor 1 outputs an alarm signal. Here, the “report signal” is a signal indicating that an abnormality such as a fire or a gas leak has been detected, and is a signal output from the sensor 1 as described above. With respect to this alarm signal, in the test process, for example, when a simulated fire is generated using a test jig (not shown) for creating an environment simulating a fire around the sensor 1, the sensor 1 is output. The output alarm signal is transmitted to the receiver 4 via the communication line 5.

  On the other hand, in SB2, the test unit 462 of the receiver 4 monitors whether or not the receiver 4 has received a notification signal. Specifically, it is monitored whether a notification signal is received via the communication line 5. Then, when the notification signal is received (YES in SB2), the process proceeds to SB3. Further, when the notification signal is not received (NO in SB2), the process in SB2 is performed again.

  Next, in SB3, the test unit 462 of the receiver 4 switches the state of the receiver 4 from the initial state to the notification detection state, and notifies information related to the received notification signal. Specifically, information corresponding to the notification signal received in SB2 is specified based on the notification area specifying information stored in the storage unit 44, and the display unit 42 and the sound unit are determined based on the specification result. 43 is controlled. Details of the processing in SB3 will be described in a specific example described later.

  Next, in SB4, the test unit 462 of the receiver 4 determines whether or not a predetermined maintenance time described later has elapsed. Specifically, it is determined whether the elapsed time from the start of the processing of SB3 has passed a predetermined maintenance time. And when it determines with having passed the predetermined maintenance time (YES of SB4), it transfers to SB5. If it is determined that the predetermined maintenance time has not elapsed (NO in SB4), the processing in SB4 is performed again while maintaining the alert detection state.

  Here, the “predetermined maintenance time” is a time for maintaining the state of the receiver 4 in the SB 3. For example, as described later, the operator uses the terminal device 8 of FIG. It is set to a relatively long time (for example, 1 minute, etc.) to such a degree that the state can be reliably confirmed.

  Returning to FIG. 4, next, in SB5, the test unit 462 of the receiver 4 performs recovery processing, and then proceeds to SB1. Here, the “restoration process” is a process for restoring the receiver 4 and the sensor 1 and will be described later in detail.

  On the other hand, in SA3, the sensor 1 monitors whether the restoration process has been performed. Specifically, it is monitored whether or not the recovery process by the receiver 4 in SB5 is performed. When the restoration process is performed (YES in SA3), the sensor 1 shifts to SA1. On the other hand, when the restoration process is not performed (NO in SA3), the sensor 1 performs the process in SA3 again.

(Processing-Test processing in disaster prevention system-specific example)
The test processing in the disaster prevention system 100 when each of the sensors 1a to 1c outputs a warning signal is similar to each other. Therefore, in the following, a specific example of the test processing when the sensor 1a outputs a warning signal Will be described.

  By generating a simulated fire around the sensor 1a of FIG. 1, the sensor 1a outputs an alarm signal in SA2 of FIG. Next, after the receiver 4 receives the notification signal in SB2, the test unit 462 of the receiver 4 in SB3 specifies the communication line on which the notification signal received in SB2 is transmitted, and specifies the specified communication line. 3 specifies the indicator lamp and the alarm sound associated with the notification area specifying information in FIG. 3, turns on the specified indicator lamp, and further outputs the specified alarm voice.

  Returning to FIG. 4, in SB3, specifically, the test unit 462 of the receiver 4 specifies the communication line 5a as the communication line on which the notification signal received in SB2 is transmitted, and specifies the notification area in FIG. In the information, the “indicator light 421a” corresponding to the “communication line 5a” is specified as the indicator light corresponding to the area where the sensor connected to the communication line 5a is provided, and “sound Dsa” is further identified in the area. It is specified as an alarm sound corresponding to. Next, the test unit 462 of the receiver 4 turns on the indicator lamp 421a of FIG. 2 that is the above-mentioned specified indicator lamp, and outputs an alarm voice corresponding to the voice Dsa that is the above-mentioned specified voice to the speaker of FIG. 431 to output.

  Returning to FIG. 4, next, when it is determined that the predetermined maintenance time has elapsed in SB4, the test unit 462 of the receiver 4 stops the alarm sound output from the speaker 431 in FIG. In addition, the receiver 4 is restored by turning off all the indicator lights 421, and the sensor 1a is restored by transmitting a restoration signal to the sensor 1a outputting the alarm signal. After the processing to be performed, the process proceeds to SB1.

  Returning to FIG. 4, next, in SA3, the sensor 1a is restored by the restoration process by the receiver 4 in SB5 described above, and then moves to SA1.

(Processing-Test processing with test system)
Next, test processing in the test system 600 will be described.

  FIG. 5 is a flowchart of a test process in the test system according to the embodiment. This will be described below with reference to FIG. 1 and FIG. The test process starts when the power switch of the test system 600 is turned on.

  First, in SC1, the photographing control unit 641 of the photographing device 6 controls the photographing unit 61 so as to photograph the display unit 42 of the receiver 4 as a still image.

  Next, in SC <b> 2, the image processing unit 642 of the imaging device 6 generates still image information based on the imaging result of the imaging unit 61.

  Next, in SC3, the control unit 64 of the imaging device 6 generates an image signal based on the still image information generated in SC2, and controls the communication unit 62 so as to output the generated image signal. Here, the “image signal” is a signal indicating still image information generated by the image processing unit 642. Under the control of SC3, the communication unit 62 outputs an image signal via the connection unit 45 of the receiver 4 to which the photographing apparatus 6 is connected and the telephone communication line 3.

  Next, in SC4, the control unit 64 of the imaging device 6 determines whether or not a predetermined time has elapsed. Specifically, it is determined whether or not an elapsed time from the start of the processing of SC1 has passed a predetermined time. If it is determined that the predetermined time has elapsed (YES in SC4), the process proceeds to SC1. If it is determined that the predetermined time has not elapsed (NO in SC4), the process in SC4 is performed again. That is, for the photographing device 6, the processing of SC1 to SC3 is repeated every time a predetermined time elapses in SC4.

  On the other hand, in SD1, the control unit 86 of the terminal device 8 monitors whether or not the communication unit 81 has received an image signal (SD1). Specifically, it is monitored whether an image signal is received via wireless communication with the wireless repeater 7. When an image signal is received (YES in SD1), the process proceeds to SD2. If no image signal is received (NO in SD1), the SD1 process is performed again.

  Next, in SD2, the information acquisition unit 861 of the terminal device 8 acquires still image information from the image signal received in SD1.

  Next, in SD3, the control unit 86 of the terminal device 8 displays an image corresponding to the still image information acquired in SD2 on the display unit 83, and then proceeds to SD1. That is, the terminal device 8 repeatedly performs the processing of SD2 and SD3 every time an image signal is received by SD1.

The image of the display unit 42 of the receiver 4 in the state is displayed. Next, when the predetermined maintenance time has elapsed, the receiver 4 is restored and the indicator lamp 421a is extinguished. Therefore, the display unit 83 of the terminal device 8 includes the receiver 4 in a state in which all the indicator lamps 421 are extinguished. The image on the display unit 42 is displayed again.

  Next, when the sensor 1b shown in FIG. 1 is issued, the wireless repeater 7 is placed around the sensor 1b (that is, so that good wireless communication is performed between the terminal device 8 and the wireless repeater 7). The sensor 1b is notified after reconnecting to the connector 22b of the transmitter 2b provided in the area B). In this case, the display unit 83 of the terminal device 8 displays an image of the display unit 42 of the receiver 4 in a state where the indicator lamp 421b of FIG. 4 images on the display unit 42 are displayed again.

  Next, when the sensor 1c of FIG. 1 is issued, since the wireless repeater 7 is already connected to the connector 22b of the transmitter 2b provided around the sensor 1c (that is, the region B), This connection state is maintained. When the sensor 1c is notified, a predetermined image is displayed on the display unit 83 of the terminal device 8 in the same manner as when the sensor 1b is notified.

  Finally, when the operation test of the disaster prevention system 100 is finished, the operation mode of the receiver 4 is switched to the normal monitoring mode after removing the support arm 91 of FIG. 2, the imaging device 6 and the wireless repeater 7 of FIG. To complete the operation test.
