<Outline of the embodiment>
An outline of the embodiment will be described with reference to FIG.
FIG. 1 is a diagram schematically showing a usage scene of the test apparatus 100 according to the embodiment. The test device 100 according to the embodiment is a device suitable for inspecting a fire detector 200 provided at a high place such as a ceiling C. The user U connects the rod-shaped member 16 that serves as the handle of the user U to the test device 100 to perform the inspection. Therefore, the test device 100 has a housing 15 having an opening for covering the fire detector 200, and a connecting portion 17 for connecting the rod-shaped member 16. Here, the connecting portion 17 for connecting the rod-shaped member 16 is provided outside the housing 15. Although two fire sensors 200 of the first fire sensitive knowledge unit 200a and the second fire sensitive knowledge unit 200b is shown in FIG. 1, except where specifically distinguished hereinafter, simply "fire detector 200 ”is described.

Inside the housing 15, a device for inspecting the fire detector 200 and a camera for capturing the state of the fire detector 200 are provided. The image of the camera provided in the housing 15 is transmitted to the communication terminal 300 at the user U's hand. As a result, by using the test device 100 according to the embodiment, the user U can carry out an operation test of the fire detector 200 while observing the image projected on the communication terminal 300 at hand, and the inspection target is the height of the ceiling C or the like. The operation test can be easily performed even if it is in the place.

<Configuration of test device 100 and appearance of communication terminal 300>
FIG. 2 is a diagram showing the configuration of the test device 100 and the appearance of the communication terminal 300 according to the embodiment. The test device 100 includes a pseudo fire generation unit 11, an operation detection unit 12, an image pickup unit 13, and a sensor illumination unit 18 inside the housing 15. The test device 100 also includes a communication unit 80 and an antenna 82 outside the housing 15.

The pseudo fire generation unit 11 can generate a pseudo fire. More specifically, in the pseudo-fire generating section 11, for example, liquid paraffin is continuously poured into an ultrasonic vibrator little by little, or liquid paraffin is sealed in a cylinder pressured with nitrogen or the like, and a cylinder valve is used when necessary. Pseudo-smoke is generated by operating a button and spraying it. The pseudo-fire generating unit 11 is also equipped with a heater and a fan, which are operated to inject hot air.

Generally, the fire detector 200 emits an operation confirmation lamp 210 to notify the fire when a fire occurs. The operation detection unit 12 detects the light generated by the fire detector 200 in response to the pseudo fire generated by the pseudo fire generation unit 11 by the camera. By determining whether or not this can be detected, the operation detection unit 12 can determine whether or not the fire detector 200 has operated normally.

The image pickup unit 13 is a camera that takes an image of the fire detector 200. Further, the communication unit 80 is provided with an antenna 82 and can communicate with the communication terminal 300 owned by the user U. By using the antenna 82, the communication unit 80 transmits the image 131 imaged by the imaging unit 13 to the communication terminal 300.

The sensor illumination unit 18 is a light emitting element such as an LED (Light Emitting Diode). The detector illumination unit 18 can illuminate the fire detector 200 by emitting light. The communication terminal 300 is a terminal capable of communicating with the fire detector 200, and includes a display unit 310 for displaying an image received from the fire detector 200. The communication terminal 300 is realized by, for example, a general-purpose computer such as a smartphone, a tablet PC (Personal Computer), a phablet, or a notebook PC, or a dedicated computer including a calculation resource and a display unit. The user U can determine whether or not the fire detector 200 is operating normally by checking the operation confirmation light 210 displayed on the image 131 displayed on the display unit 310 of the communication terminal 300.

<Functional configuration of test device 100>
FIG. 3 is a diagram schematically showing a functional configuration of the test apparatus 100 according to the embodiment. The test device 100 includes a pseudo fire generation unit 11, an operation detection unit 12, an imaging unit 13, a proximity sensor 14, a sensor lighting unit 18, a control unit 40, a communication unit 80, and an antenna 82.

The control unit 40 is composed of a CPU (Central Processing Unit) and a memory included in the test apparatus 100. The control unit 40 functions as an overall control unit 41, an inspection control unit 42, an imaging control unit 45, an irradiation control unit 46, and a communication control unit 47 by executing a program stored in a storage unit (not shown).

The overall control unit 41 controls each unit of the control unit 40 as a whole. When the proximity sensor 14 detects the approach of an object, the overall control unit 41 receives a proximity signal indicating that the approach of the object is detected from the proximity sensor 14.
Although not shown in FIG. 2, the proximity sensor 14 is provided outside the housing 15. The proximity sensor 14 detects the approach of an object under the control of the overall control unit 41. Therefore, the proximity sensor 14 can also detect that the test device 100 has approached the fire detector 200.

The irradiation control unit 46 controls the lighting and extinguishing of the sensor lighting unit 18 under the control of the overall control unit 41. The overall control unit 41 causes the irradiation control unit 46 to light the sensor illumination unit 18 when the proximity sensor 14 detects a proximity signal, that is, the proximity sensor 14 detects the approach of an object. The overall control unit 41 also causes the image pickup control unit 45 to start imaging when the proximity signal is detected from the proximity sensor 14. As a result, when the test device 100 is away from the fire detector 200, it is possible to prevent the detector illumination unit 18 from irradiating light. Similarly, when the test device 100 is away from the fire detector 200, the image pickup unit 13 can suppress the image pickup.

The user U can remotely control the pseudo fire generation unit 11 by operating the communication terminal 300. Specifically, the communication control unit 47 receives the control signal of the pseudo fire generation unit 11 from the communication terminal 300 via the communication unit 80 and the antenna 82. The overall control unit 41 causes the inspection control unit 42 to operate the pseudo fire generation unit 11 based on the control signal of the pseudo fire generation unit 11 received by the communication control unit 47.

For example, when the communication control unit 47 receives a signal instructing the pseudo fire generation unit 11 to start smoking, the inspection control unit 42 starts smoking to the pseudo fire generation unit 11 under the control of the overall control unit 41. Let me. Similarly, when the communication control unit 47 receives a signal instructing the pseudo fire generation unit 11 to stop smoking, the inspection control unit 42 causes the pseudo fire generation unit 11 to stop smoking.

The communication control unit 47 transmits the image of the fire detector 200 imaged by the image pickup unit 13 to the communication terminal 300 via the communication unit 80 and the antenna 82. Therefore, the user U can remotely control the pseudo-fire generating unit 11 while looking at the communication terminal 300 owned by the user U. Since the pseudo-fire generating unit 11 can be operated only during the operation test of the fire detector 200, it is possible to suppress the smoke and heat generated by the pseudo-fire generating unit 11 during the operation test. In this way, since the smoke and heat generated by the pseudo-fire generating unit 11 can be suppressed, the consumption of the smoke material and the electric power required for generating the heat can be suppressed.

<Functional configuration of communication terminal 300>
FIG. 4 is a diagram schematically showing a functional configuration of the communication terminal 300 according to the embodiment. The communication terminal 300 includes a display unit 310, a terminal-side communication unit 320, and a terminal control unit 330.

The terminal control unit 330 is realized by the CPU and memory of the communication terminal 300. The terminal control unit 330 executes a program stored in a storage unit (not shown) of the communication terminal 300 to execute the overall control unit 331, the display control unit 332, the determination unit 333, the control signal transmission unit 334, and the terminal side communication. It functions as a control unit 335.

The terminal-side communication control unit 335 controls the operation of the terminal-side communication unit 320 under the control of the overall control unit 331. The terminal-side communication unit 320 communicates with the test device 100 and exchanges information under the operation of the terminal-side communication control unit 335. For example, the terminal-side communication unit 320 receives the image 131 imaged by the imaging unit 13 from the communication unit 80 of the test device 100. The video 131 received by the terminal-side communication unit 320 is output to the overall control unit 331 via the terminal-side communication control unit 335.

The display control unit 332 controls the operation of the display unit 310 under the control of the overall control unit 331. For example, the display control unit 332 causes the display unit 310 to display the image 131 acquired by the overall control unit 331. The determination unit 333 determines whether or not the fire detector 200 has operated normally by analyzing the image 131 acquired by the overall control unit 331. More specifically, the determination unit 333 detects whether or not the operation confirmation lamp 210 shown in the image 131 is lit. When the operation confirmation lamp 210 is lit, the determination unit 333 determines that the fire detector 200 has operated normally.

The display control unit 332 causes the display unit 310 to display the determination result of the determination unit 333. In this sense, the display control unit 332 also functions as a notification unit that notifies the user U of the determination result by the determination unit 333.

When the determination unit 333 determines that the fire detector 200 has operated normally, the control signal transmission unit 334 transmits a control signal for stopping the occurrence of a pseudo fire by the pseudo fire generation unit 11 on the terminal side. It is transmitted to the control unit 335. As a result, it is possible to suppress smoke and heat generated by the pseudo-fire generating unit 11 during the operation test of the fire detector 200. In this way, since the smoke and heat generated by the pseudo-fire generating unit 11 can be suppressed, the consumption of the smoke material and the electric power required for generating the heat can be suppressed.

<Screen example of communication terminal 300>
FIG. 5 is a diagram for exemplifying the display screen of the communication terminal 300 according to the embodiment. Specifically, FIG. 5A illustrates an example of an operation screen for the user U to remotely control the pseudo-fire generating unit 11. Further, FIG. 5B illustrates an example of a screen for notifying the user U of confirmation of the operation of the fire detector 200.

In the communication terminal 300 according to the embodiment, the display unit 310 may be a touch screen including a touch sensor. In this case, the user U can select whether to perform the heating test or the smoke test by the test apparatus 100 by selecting the test type selection tab 312 displayed on the display unit 310. The example shown in FIG. 5A shows an example in which the user U has selected the test apparatus 100 to perform a heating test. The display unit 310 also displays the image 131 of the imaging unit 13 transmitted to the communication terminal 300.

When the user U selects the start icon 314 displayed on the display unit 310, the control signal transmission unit 334 generates a control signal indicating that the heating test is started in the pseudo fire generation unit 11, and the terminal side communication control unit 335. To send. When the user U selects the stop icon 316 displayed on the display unit 310, the control signal transmission unit 334 generates a control signal indicating that the heating test is stopped in the pseudo fire generation unit 11, and the terminal side communication control unit 335. To send. As a result, the user U can remotely operate the test device 100 by operating the communication terminal 300 at hand.

When the determination unit 333 determines that the fire detector 200 has operated normally by analyzing the image 131, the determination unit 333 causes the display unit 310 to display the operation notification icon 317. More specifically, the determination unit 333 transmits a control signal indicating that the operation notification icon 317 is to be displayed to the display control unit 332. Upon receiving the control signal, the display control unit 332 causes the display unit 310 to display the operation notification icon 317. As a result, the user U can at a glance grasp that the fire detector 200 has operated normally without observing and judging the image 131 displayed on the display unit 310.

When the proximity sensor 14 detects the approach of an object (Yes in S4), the sensor illumination unit 18 starts illumination (S6), and the imaging unit 13 starts imaging (S8). The communication control unit 47 starts transmitting the image 131 imaged by the imaging unit 13 to the communication terminal 300 (S10). Here, the imaging unit 13 executes so-called panning, in which the image 131 is continuously imaged. Therefore, the communication control unit 47 also continuously transmits the video 131 to the communication terminal 300.

The terminal-side communication unit 320 of the communication terminal 300 receives the video 131 transmitted from the test device 100 (S12). When the user U of the communication terminal 300 operates the start icon 314 displayed on the display unit 310, the control signal transmission unit 334 generates a start control signal indicating that the pseudo fire generation unit 11 starts to generate a pseudo fire. Then, the terminal side communication control unit 335 is made to transmit (S14).

The inspection control unit 42 of the test apparatus 100 causes a pseudo fire in the pseudo fire generation unit 11 according to the control signal transmitted from the communication terminal 300 (S16). Until the communication unit 80 receives a stop control signal indicating that the occurrence of a pseudo fire is stopped from the communication terminal 300 via the antenna 82 (No in S18), the communication unit 80 receives the stop control signal. stand by.

The determination unit 333 of the communication terminal 300 analyzes the video 131 received from the test device 100 (S20). The determination unit 333 returns to step S20 and continues the image analysis until it is determined that the fire detector 200 is operating normally (No in S22). When the determination unit 333 determines that the fire detector 200 is operating normally (Yes in S22), the control signal transmission unit 334 controls the pseudo fire generation unit 11 to indicate that the pseudo fire is stopped. A signal is generated and transmitted to the terminal-side communication control unit 335 (S24). The display control unit 332 causes the display unit 310 to display the determination result of the determination unit 333 (S26).

When the communication unit 80 of the test apparatus 100 receives a control signal from the communication terminal 300 via the antenna 82 indicating that the pseudo fire is stopped (Yes in S18), the inspection control unit 42 causes the pseudo fire to occur. Unit 11 stops the occurrence of a pseudo fire (S28). The communication control unit 47 stops transmitting the image 131 captured by the imaging unit 13 to the communication unit 80 (S30).

As described above, according to the test apparatus 100 according to the embodiment, it is possible to facilitate an operation test of an inspection object at a high place.
