Description

[Technical field]

[0001] The present invention relates to a method for inspecting the light emission operation of a device that, in response to detection by a predetermined detector such as a fire receiver, emits light to notify the fact of the detection. [Background technology]

[0002] There is a device that notifies the detection of a predetermined event by a sensor or the like by emitting light from a light emitting means. For example, in an automatic fire alarm system (automatic fire alarm system), there is a fire receiver connected to a plurality of sensors that detect the occurrence of a fire, such as smoke or heat, and this fire receiver is provided with a light emitting means for notifying the detection by each sensor. For example, in order to notify the detection of a sensor installed on each floor of a building, a different light emitting means is provided for each sensor in the fire receiver, and when sensor A installed on the second floor of the building detects the occurrence of a fire, the light emitting means corresponding to this sensor A emits light. With this configuration, in the event of a fire, the building manager or disaster prevention officer can immediately know the location of the fire by visually checking which light emitting means of the fire receiver has emitted light. A typical example of such an automatic fire alarm system is disclosed in Patent Document 1. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2014-056368 Summary of the Invention [Problem to be solved by the invention]

[0004] However, since it is important that the light emitting means of such a fire receiver reliably emits light when a fire occurs, the building manager must periodically inspect the light emitted by the light emitting means of the fire receiver. Conventionally, two inspectors work in pairs, with one inspector sequentially activating the detection of multiple sensors in the building one by one, while the other waits in front of the light emitting means of the event receiver to check that the light emitting means corresponding to the activated sensor has emitted light. The two inspectors communicate with each other using a walkie-talkie or the like, and check whether the light emitting means for each sensor has emitted light normally. In large buildings, it is necessary to work in multiple pairs and carry out inspections over a long period of time. It would be useful if such inspections could be simplified and manpower-saving.

[0005] In view of the above circumstances, an object of the present invention is to provide a solution that can simplify and reduce the manpower required for light emission inspection of light-emitting means for notifying events such as the occurrence of a fire. [Means for solving the problem]

[0006] A system according to one aspect of the present invention is an inspection system that inspects the light emitting operation of a light emitting means that emits light in response to a detection signal from a predetermined sensor. This inspection system includes a sensor driver, a light emitting detection means, a communication means, and a portable user terminal. The sensor driver is held by a user and has a function of intentionally operating the sensor by emitting a detection target of the sensor. The light emitting detection means is provided near the light emitting direction side of the light emitting means and has a function of detecting the light emitting operation of the light emitting means. The communication means has a function of transmitting the detection result of the light emitting detection means based on the detection signal from the light emitting detection means via a network to a portable user terminal carried by the user. The portable user terminal has a function of displaying the detection result transmitted from the light emitting detection means.

[0007] According to this inspection system, a user (worker) goes to the site where the detector is installed carrying the detector driver, and when the user intentionally drives the detector with the detector driver, the light emission detection means detects that the light emitting means has emitted light in response to the driving of the detector, and the detection result is transmitted to and displayed on the user terminal. The user can confirm that the light emitting means has responded to the detector and emitted light normally by visually checking the detection result displayed on the user terminal. Therefore, after installing the light emission detection means near the light emitting means, the user can go to the site where the detector is installed carrying the detector driver and the user terminal and perform the inspection by himself. Effect of the Invention

[0008] The present invention can simplify and manpower-saving the light emission inspection of light-emitting means for notifying an event such as the occurrence of a fire. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] An embodiment of the present invention will be described in detail below. Fig. 1 is a diagram showing a system according to an embodiment of the present invention. The system includes a test target device 10 having a light emitting means for event notification, and a test system 20 for testing the light emitting operation of the test target device 10.

[0011] The inspection target device 10 is a device having a function of notifying the occurrence of a predetermined event by emitting light using a light-emitting means for notification. For example, in this embodiment, a fire alarm system 10 that notifies the occurrence of a fire (event) will be described as an example. The fire alarm system 10 is provided in facilities where many people enter and exit, such as hotels, inns, complex buildings, multi-tenant buildings, schools, libraries, etc. The fire alarm system 10 is connected to multiple sensors 1 that detect heat, smoke, flames, etc. and emit detection signals, and receives detection signals from each sensor 1. The fire alarm system 10 includes multiple light-emitting units 10a. The fire alarm system 10 associates each light-emitting unit 10a with a specific sensor 1, and is configured to cause a corresponding specific light-emitting unit 10a to emit light when a detection signal is received from a certain sensor 1. Each light-emitting unit 10a is associated with one or more sensors 1. Ideally, it is preferable that each sensor 1 and each light-emitting unit 10a are associated one-to-one. In this case, a different light-emitting unit 10a will emit light for each sensor 1 that has triggered an alarm, making it easiest to identify the location of the fire. However, in the case of a facility such as a large building with many floors, more sensors 1 than the total number of light-emitting units 10a provided in the fire alarm system 10 may be required. In such a case, two or more sensors 1 (for example, multiple sensors 1 installed scattered in each of multiple areas in the facility) can be grouped together and associated with the same light-emitting unit 10a, thereby making it possible to identify the location of the fire in each area (for example, floor). In addition, a location indicator 10b indicating the installation location of one or more sensors 1 associated with each light-emitting unit 10a is provided in association with each light-emitting unit 10a. With this configuration, when any sensor 1 detects a fire, the building manager or disaster prevention officer can immediately know the location of the fire by visually checking the light-emitting unit 10a of the fire alarm system 10.

[0012] The inspection system 20 is a system for inspecting the light emitting operation of the inspection target device 10 (fire alarm system 10). If the light emitting unit 10a of the fire alarm system 10 does not emit light when a fire breaks out due to a malfunction or the like, there is a risk of serious human damage. For this reason, it is important to inspect the fire alarm system 10 periodically to confirm that the corresponding light emitting unit 10a normally emits light in response to the detection signal of the sensor 1.

[0013] The inspection system 20 includes a detection unit 21, a communication unit 22, a server 23, a user terminal 24, and a sensor driver 25. The detection unit 21 is a sensor that detects the light emitting state of the light emitting unit 10a, and outputs a detection signal in response to the detection. The detection unit 21 is connected to the communication unit 22 and outputs the detection signal to the communication unit 22. The communication unit 22 transmits the detection result to the server 23 via the network 2 based on the detection signal received from the detection unit 21. The server 23 is a server that manages the inspection by the inspection system 20. The server 23 is accessible from the user terminal 24. The server 23 transmits the detection result of the detection unit 21 to the user terminal 24 via the network 2 based on the detection result received from the communication unit 22. The user terminal 24 is a terminal that is carried and operated by an operator who performs the inspection work of the fire alarm system 10 using the inspection system 20. The user terminal 24 notifies the operator of the detection result by displaying the detection result received from the server 23. The detector driver 25 is a device carried by a worker performing an inspection operation, and is used to intentionally cause the detector 1 to perform a detection operation.

[0014] The sensor driver 25 is a device that emits the object to be detected by the sensor 1. For example, if the sensor 1 is a smoke sensor, the sensor driver 25 has a mechanism that emits smoke. If the sensor 1 is a heat sensor, the sensor driver 25 has a mechanism that emits heat, such as a heater or a combustion device. The sensor driver 25 is provided with a switch that is operated by an operator, and the mechanism operates in response to the switch operation by the operator.

[0015] FIG. 2 is a diagram showing an example of the detection unit 21 of the inspection system 20. In this example, the detection unit 21 is composed of a plurality of optical sensors 21a. The optical sensors 21a are provided in at least the same number as the light-emitting units 10a of the fire alarm system 10, and each optical sensor 21a is capable of receiving light from a different light-emitting unit 10a. Each optical sensor 21a has a light-receiving element, receives light, and outputs an electric signal (detection signal). The optical sensor 21a may be, for example, an illuminance sensor equipped with a phototransistor, or a color sensor capable of outputting different color signals of RGB (red, green, blue). Each optical sensor 21a is connected to the communication unit 22.

[0016] FIG. 3 is a diagram showing an example of the configuration of the optical sensor 21a. FIG. 3 is a diagram showing the optical sensor 21a as viewed from the side. The optical sensor 21a has a main body 210a having a light receiving element. The main body 210a is fixed to a fixed plate 210b, and an opening 210c is provided in a portion of the fixed plate 210b corresponding to the light receiving portion so as not to block the light receiving portion of the main body 210a. The light receiving element of the main body 201a is configured to receive light through the opening 210c. In addition, a suction cup 210d is fixed to the fixed plate 210b. The suction cup 210d is fixed to the fixed plate 201b so that the suction cup surface is on the opposite side to the main body 210a across the fixed plate 210b, and is spaced apart to a certain extent from the opening 201c of the fixed plate 210b so as not to interfere with light reception. Furthermore, the main body 210a is provided with a cable 210e for transmitting an electric signal (detection signal) generated by the main body 210a to the communication unit 22. One end of the cable 210e is connected to the main body 210a, and the other end is connected to the communication unit 22. With this configuration, by fixing the suction cup 210d near the light-emitting unit 10a so that the light-emitting unit 10a is located directly under the opening 210c, the optical sensor 21a can be fixed in a position where it receives light from the light-emitting unit 10a.

[0017] 4 is a diagram showing a state in which the optical sensors 21a are fixed to the light-emitting units 10a of the fire alarm system 10. As shown in the figure, the optical sensors 21a are installed so as to receive light from different light-emitting units 10a.

[0018] 5 is a diagram showing another example of the detection unit 21 of the inspection system 20. In this example, the detection unit 21 is composed of a camera 21b. The camera 21b is an imaging device that has an imaging element and captures images in an analog or digital manner. The camera 21b has components well known to those skilled in the art, such as an imaging element, a lens, and a memory. In this example, the camera 21b is installed near the fire alarm system 10 with the imaging direction of the camera 21b facing all the light-emitting units 10a so that all the light-emitting units 10a fall within the imaging range of the camera 21b.

[0019] The detection unit 21 may detect the light emitted by the light-emitting unit 10a at a predetermined timing (for example, at a predetermined time such as every second) after the power is turned on. For example, if the detection unit 21 is composed of a plurality of optical sensors 21a, each optical sensor 21a outputs a luminance value indicating luminance and each RGB value as a detection signal at a predetermined time. For example, if the detection unit 21 is a camera 21b, the camera 21b outputs a captured image as a detection signal at a predetermined time. The communication unit 22 transmits the detection signal output by the detection unit 21 to the server 23.

[0020] The server 23 receives the detection signal output by the detection unit 21 at a predetermined timing via the communication unit 22, and generates a detection result based on the detection signal. Specifically, the server 23 detects that the light-emitting unit 10a has emitted light based on the detection signal, and outputs the detection signal. For example, when the detection unit 21 is a plurality of optical sensors 21a and the detection result is a luminance value output from each optical sensor 21a, when the server 23 receives a detection signal indicating that the luminance value of any of the optical sensors 21a has exceeded a predetermined light-emitting threshold, the server 23 may output a positive detection signal indicating that the light-emitting unit 10a has emitted light in response to the detection signal. Also, for example, when the detection result is an RGB value by each optical sensor 21a, when the server 23 receives a detection signal indicating that an RGB value corresponding to a predetermined color (e.g., red or orange) has been output from any of the optical sensors 21a, the server 23 may output a positive detection signal indicating that the light-emitting unit 10a has emitted light in response to the detection signal. Also, for example, when the detection unit 21 is the camera 21b and the detection result is an image captured by the camera 21b, an image recognition process is performed to compare a reference captured image (an image captured when the light-emitting unit 10a is not emitting light) with the captured image indicated by the detection signal, and if it is recognized that any of the light-emitting units 10a has emitted light, a positive detection signal is output in response to this.

[0021] In addition, during the inspection operation by the server 23, the detection unit 21 needs to be properly fixed in a position and posture that allows the detection unit 21 to correctly detect the light emitted by the light-emitting unit 10a. If the detection unit 21 is moved without the worker's notice during the detection operation and is no longer able to detect the light emitted by the light-emitting unit 10a, it becomes difficult to execute the detection operation. For example, when the detection unit 21 is composed of multiple optical sensors 21a, if any of the optical sensors 21a falls off from the position near the light-emitting unit 10a where it was originally attached, it will no longer be able to receive light from the light-emitting unit 10a and will no longer be able to detect the light emitted. Falling off refers to, for example, when the optical sensor 21a is attached near the light-emitting unit 10a by a suction cup 210d, the suction cup 210d comes off and the optical sensor 21a becomes detached. In addition, when the detection unit 21 is a camera 21b, if the imaging range of the camera 21b deviates from the light-emitting unit 10a, it will no longer be able to recognize the image of the light-emitting unit 10a and will no longer be able to detect the light emitted.

[0022] Therefore, while receiving the detection signal of the detection unit 21 at a predetermined timing, the server 23 judges whether the detection unit 21 is fixed in a position and posture where the detection unit 21 can detect the light emission of the light-emitting unit 10a, and if it judges that the detection unit 21 is not fixed in a position and posture where the detection unit 21 can detect the light emission of the light-emitting unit 10a, it generates an error message indicating that and notifies the user terminal 24. Specifically, when the detection unit 21 is the optical sensor 21a, the detection signals (brightness values ​​and RGB values) of all the optical sensors 21a at a certain time are stored as reference values, and each time a detection signal is received, it is judged whether the activation value or RGB value of any of the optical sensors 21a indicates an abnormal value. For example, in the case of the brightness value, if a brightness value change occurs that does not exceed the light emission threshold for detecting the light emission of the light-emitting unit 10a but exceeds a predetermined abnormality detection position less than the light emission threshold, it can be judged that the optical sensor 21a has fallen off. In the case of RGB values, it can be determined that the light sensor 21a has fallen off when the RGB values ​​change from the reference values ​​to RGB values ​​that indicate a color different from the color (e.g., red or orange) that detects the light emitted by the light-emitting unit 10a. When the above-mentioned changes occur in the luminance values ​​or RGB values ​​of multiple light sensors 21a, it can be determined that multiple light sensors 21a have fallen off. However, it is difficult to imagine that too many light sensors 21a will fall off at the same time. If the luminance values ​​or RGB values ​​of many light sensors 21a change at the same time, it is highly likely that a change has occurred in the brightness of the environment in which the detection unit 21 is installed (e.g., the brightness of the room in which the fire alarm system 10 is installed) rather than a falloff. For this reason, in order to prevent such an environmental change from being erroneously detected as a falloff of the light sensor 21a, it is advisable to determine that there has been an environmental change in brightness rather than a falloff of the light sensor 21a when the luminance values ​​or RGB values ​​of a certain percentage or more of multiple light sensors 21a among all the light sensors 21a show the above-mentioned changes at the same time. When the detection unit 21 is a camera 21b, an image captured by the camera 21b at a certain point in time is stored as a reference image, and is compared with the captured image indicated by the detection signal. If a predetermined change occurs throughout the captured image, it is determined that the imaging range of the camera 21b has deviated from the light-emitting unit 10a.On the other hand, if there is a change in luminance across the entire captured image compared to the reference image, although not to the extent of the predetermined change, it may be determined that there has been a change in environmental brightness.

[0023] FIG. 6 is a flowchart showing an example of a judgment flow of the server 23 based on the luminance value when the detection unit 21 is composed of a plurality of optical sensors 21a. After the detection unit 21 is powered on, the detection unit 21 generates the luminance value of each optical sensor 21a as a detection signal at a predetermined timing, and the communication unit 22 transmits the detection signal to the server 23 (S10). The server 23 first stores the luminance value received at a predetermined time as a reference value (S11, S12). Thereafter, the server 23 compares the luminance value with the reference value each time the server 23 receives the luminance value. If the comparison shows that the luminance values ​​of a plurality of optical sensors 21a that are equal to or greater than a predetermined ratio of all the optical sensors 21a have changed, the server 23 determines that there has been a change in the brightness of the environment (S13) and updates the luminance value after the change as the reference value (S14). On the other hand, if the comparison shows that the luminance value of a certain optical sensor 21a has changed beyond a predetermined first threshold, the server 23 determines that the certain optical sensor 21a has emitted light and outputs a positive detection signal (S15). On the other hand, if the luminance value of one or more optical sensors 21a that is less than the predetermined ratio exceeds a second threshold as a result of the comparison, it is determined that the optical sensor 21a has fallen off, and an error message is output (S16). Here, the second threshold is a value lower than the first threshold.

[0024] FIG. 7 is a flowchart showing an example of a judgment flow of the server 23 based on RGB values ​​when the detection unit 21 is composed of multiple optical sensors 21a. After the detection unit 21 is powered on, the detection unit 21 generates the RGB values ​​of each optical sensor 21a as a detection signal at a predetermined timing, and the communication unit 22 transmits the detection signal to the server 23 (S20). The server 23 first stores the RGB values ​​received at a predetermined time as reference values ​​(S21, S22). Thereafter, the server 23 compares the RGB values ​​with the reference values ​​each time it receives an RGB value. If the comparison shows that the RGB values ​​of a plurality of optical sensors 21a that account for a predetermined ratio or more of all the optical sensors 21a have changed, it is determined that there has been a change in the brightness of the environment (S23), and the RGB values ​​after the change are updated as the reference values ​​(S24). On the other hand, if the comparison shows that the RGB values ​​of a certain optical sensor 21a indicate a predetermined emission color (e.g., red or orange), it is determined that the certain optical sensor 21a has emitted light, and a positive detection signal is output (S25). On the other hand, if the RGB value of one or more optical sensors 21a that is less than the predetermined ratio indicates a predetermined color different from the emitted light color, it is determined that the optical sensor 21a has fallen off and an error message is output (S26).

[0025] FIG. 8 is a flow chart showing an example of a judgment flow of the server 23 based on a captured image in the case where the detection unit 21 is composed of the camera 21b. After the detection unit 21 is powered on, the detection unit 21 generates a captured image of the camera 21b as a detection signal at a predetermined timing, and the communication unit 22 transmits the detection signal to the server 23 (S30). The server 23 first stores the captured image received at a predetermined time as a reference image (S31, S32). Thereafter, the server 23 compares the captured image with the reference image every time the server 23 receives the captured image. If the comparison result shows that there is a change in luminance exceeding a first threshold value in a portion of a predetermined percentage or more of the entire captured image and that the change in luminance varies from pixel to pixel, the server 23 determines that the shooting direction of the camera 21b has deviated and outputs an error message (S36). On the other hand, if the comparison result shows that there is a change in luminance exceeding a second threshold value in a portion of the predetermined percentage or more of the entire captured image and that the change in luminance varies from pixel to pixel, the server 23 determines that there is a change in the brightness environment (S33), and updates the captured image after the change as the reference image (S34). The second threshold value is preferably a threshold value lower than the first threshold value. On the other hand, if the comparison shows that there is a change in luminance in a part of the captured image that corresponds to the light-emitting unit 10a, it is determined that the light sensor 21a has emitted light, and a positive detection signal is output (S35).

[0026] As described above, the server 23 determines whether the light-emitting unit 10a is emitting light at any time based on the inspection signal of the detection unit 21, and outputs the result as the detection result. The detection result is transmitted to the user terminal 24 and displayed on the user terminal 24. By checking the detection result displayed on the user terminal 24, the worker can check whether the light-emitting unit 10a has normally emitted light in response to the driving of the detector 1.

[0027] FIG. 9 is a diagram showing an example of displaying the detection result received by the user terminal 24 from the server 23. As shown in FIG. 9, the display unit of the user terminal 24 displays an icon S1 corresponding to the light-emitting unit 10a to be inspected. The icons S1 are displayed, for example, in a tiled form, in the same number as the light-emitting units 10a provided in the fire alarm system 10. In the example shown in FIG. 9, the fire alarm system 10 is equipped with 20 light-emitting units 10a, and 20 corresponding icons S1 are displayed. Each time the user terminal 24 receives a positive detection result indicating the emission of light from any of the light-emitting units 10a from the server 23, the user terminal 24 changes the display mode of the icons S1 in a predetermined order, starting from a predetermined icon S1. For example, as shown in FIG. 9(a), it is preferable to change the display mode of the icon S1 from the top left icon S1 to the right, and then to move down one level and change the display mode of the icon S1 from the leftmost icon S1 to the right. The change in the display mode may be, for example, by changing the color, brightness, blinking, or enlarging the size of the icon S1 from the default display mode of the icon S1. By visually checking such a change in the display mode of the icon S1 on the user terminal 24, the worker can inspect the light emission of the light-emitting unit 10a. On the other hand, when the user terminal 24 receives the above error message from the server 23, as shown in FIG. 9(b), it displays a message S2 urging the user to check on-site because an abnormality has occurred in the installation state of the detection unit 21 and the light emission of the light-emitting unit 10a cannot be detected.

[0028] FIG. 10 is a diagram showing a state where an operator inspects the fire alarm system 10 using the inspection system 20. As shown in FIG. 9, the operator 50 first installs the detection unit 21 and the communication unit 22 in a place where the detection unit 21 can detect the light emitted by the light emitting unit 10a, and starts output processing of the detection result by judging the detection operation of the light emitting unit 10a by the detection unit 21 and the light emission by the server 23 by turning on the power of the detection unit 21 and the communication unit 22. Next, the operator 50, carrying the user terminal 24 and the detector driver 25, goes to the vicinity of the detector 1 to be inspected in the facility 3 where the fire alarm system 10 and the detector 1 are installed. In the vicinity of the detector 1, the operator 50 operates the detector driver 25 to intentionally cause the detector 1 to perform a detection operation. In addition, the worker 50 accesses (logs in to) the server 23 with the user terminal 24 in parallel with driving the detector driver 25, and the user terminal 24 waits to receive the detection result from the server 23. Then, as soon as the light-emitting unit 10a emits light based on the detection operation of the detector 1, the detection unit 21 detects this light emission, and the server 23 judges the light emission of the light-emitting unit 10a based on the detection signal from the detection unit 21 and outputs the detection result. By logging in to the server 23, the user terminal 24 receives and displays the detection result from the server 23. In this way, the worker 50 can visually confirm that the corresponding light-emitting unit 10a has normally emitted light in response to the detection operation of the detector 1 using the detector driver 25 by visually checking the display on the user terminal 24. By carrying out the above inspection procedure for all the detectors 1 in the facility 3 (i.e., for all the light-emitting units 10a), it is possible to confirm that all the detectors 1 in the facility 3 are operating normally.

[0029] The server 23 may be configured to accept and manage the registration of installation information of the detector 1 in the facility where the user performs the inspection using the inspection system 20 (i.e., for each worker 50 or for each organization such as a company to which the worker 50 belongs) performs the inspection. The server 23 may also be configured to manage the completion state of the inspection of each detector 1 as an inspection status. FIGS. 11(a) and 11(b) are diagrams showing tables in which the installation information of the detector 1 and the inspection status managed by the server 23 are associated with each other. As shown in FIGS. 11(a) and 11(b), the detector installation information and the inspection status are associated with each user ID. The user ID is an ID issued for each user (an individual worker, a company or organization to which the worker belongs, etc.) who performs the inspection using the inspection system 20. The worker 50 can log in to the server 23 using his / her own ID from the user terminal 24. The detector installation information is information of the detector 1 in the facility where the user of the corresponding user ID performs the inspection. The detector installation information shown in FIG. 11(a) is, for example, a map M (layout diagram, floor plan, etc.) of a facility in which icons S3 of a plurality of detectors 1 to be inspected are plotted at their respective installation positions, as shown in FIG. 12. The detector installation information shown in FIG. 11(b) is the number of light-emitting units 10a that emit light corresponding to each detector 1. In addition, the detector installation information may be, for example, the number of detectors 1 or a list of the detectors 1. The inspection status is information indicating how much of the inspection of all the light-emitting units 10a to be inspected indicated by the detector installation information has been completed. The inspection status indicates, for example, the ratio of the number of light-emitting units 10a that have been inspected to all the light-emitting units 10a to be inspected. The server 23 updates the inspection status every time it determines that the light-emitting unit 10a has emitted light and outputs the above-mentioned positive detection signal.

[0030] As described above, the worker 50 registers the installation information of the light-emitting unit 10a to be inspected and the corresponding detector 1 in the server 23, and starts the inspection. In the inspection, the detection unit 21 is installed near the light-emitting unit 10a of the fire alarm system 10, and the worker 50 inspects the light-emitting operation of the light-emitting unit 10a using the user terminal 24 and the detector driver 25, as shown in Fig. 10. Figs. 13 and 14 are diagrams showing the procedure of the inspection by the inspection system 20.

[0031] 13 is a flowchart showing the operation of the server 23 to register sensor installation information. First, the user logs in to the server 23 from the user terminal 24 (step S40). The user terminal 24 activates a user interface (UI) for registering sensor installation information and accepts input of sensor installation information (step S41). In step S41, for example, input of the facility map M and the number of light-emitting units 10a described above is accepted. In step S41, the user terminal 24 transmits the accepted sensor installation information to the server 23. The server 23 accepts the registration of the sensor installation information received from the user terminal 24 (step S42) and registers the sensor installation information in association with the logged-in user ID (step S43).

[0032] FIG. 14 is a flow chart showing a procedure in which the worker 50 inspects the light emitting operation of the light emitting unit 10a in the inspection system 20 after registering the detector installation information in the server 23. First, the user logs in to the server 23 from the user terminal 24 (step S100). The server 23 performs user authentication based on the user ID entered at the time of login (step S101), reads out the detector installation information associated with the user ID by referring to the table shown in FIG. 11, and notifies the user terminal 24 (step S102). The user terminal 24 receives the detector installation information (step S103), and is ready to start the inspection, and waits for the reception of the detection result from the server 23. At this time, the user terminal 24 displays the icon S1 shown in FIG. 9 (step S104). When the received detector installation information indicates the number of the light emitting units 10a, the icon S1 may display the same number of icons S1 by referring to the detector installation information. 12, the user terminal 24 may display the map M together with the icon S1 or selectively so that the worker 50 can view it at any time. Next, the worker 50 intentionally drives the detector 1 by bringing the detector driver 25 close to the detector 1 at the site where the detector 1 to be driven is installed. When the detector 1 is driven by this series of inspection actions, the corresponding light-emitting unit 10a of the fire alarm system 10 emits light, and the detection unit 21 of the inspection system 20 detects the light emission and outputs a detection signal (step S105), and the communication unit 22 transmits the detection signal to the server 23 (step S106). When the server 23 receives the detection signal (step S107), it judges the light emission of the light-emitting unit 10a based on the signal, outputs a positive detection result, and transmits it to the user terminal 24 (step S108). When the user terminal 24 receives a positive detection result (step S109), it changes the display mode of the icon S1 to notify that the light-emitting unit 10a has emitted light (step S110). In response to the transmission of the positive detection result indicating that the light-emitting unit 10a has emitted light, the server 23 updates the test status corresponding to the logged-in user ID (step S111).

[0033] FIG. 15 shows another embodiment in which the optical sensor 21a is used as the detection unit 21 as shown in FIGS. 2 to 4. In the example shown in FIG. 4, the optical sensors 21a are arranged one by one in a one-to-one correspondence with one light-emitting unit 10a. In contrast, in the example shown in FIG. 15, an optical sensor board 21c is used in which a plurality of optical sensors 21a are arranged in a matrix at a predetermined interval. The optical sensor board 21c is, for example, a plate-shaped member made of wood, resin, metal, or the like, and a plurality of optical sensors 21a are arranged in a matrix on one side (in the example of FIG. 15, a total of 28 optical sensors 10a are arranged, four vertically and seven horizontally). The intervals between the optical sensors 21a are set to be narrower than the intervals between the light-emitting units 10a in a typical inspection target device 10 that may be an inspection target, and all the intervals are constant. The wiring of each optical sensor 21a is collected and connected to the communication unit 22.

[0034] When such an optical sensor board 21c is placed on the light-emitting unit 10a of the inspection target device 10 with a gap between them, with the surface on which the optical sensor 21a is provided facing the light-emitting unit 10a, at least one of the optical sensors 21a can detect the light emitted by each light-emitting unit 10a according to the positional relationship between the optical sensor board 21c and the light-emitting unit 10a, as shown in Figs. 16 to 17. That is, even if the positional relationship between each optical sensor 21a and the light-emitting unit 10a is not exactly determined in a one-to-one relationship, the light of the light-emitting unit 10a emitted through the gap secured between the optical sensor board 21c and the light-emitting unit 10a is detected by the optical sensor 10a located near the light-emitting unit 10a. For example, in the example of Figs. 16 to 17, when the light-emitting unit 10a at the upper left (the light-emitting unit 10a labeled "1F South Corridor") emits light, the two optical sensors 21a-1 and 21a-2 at the upper left in the optical sensor board 21c detect the light emission. When the upper right light-emitting unit 10a (the light-emitting unit 10a labeled "1F East Corridor") emits light, the two light sensors 21a-3 and 21a-4 located in the upper middle of the light sensor board 21c detect the light emission. When the center left light-emitting unit 10a (the light-emitting unit 10a labeled "1F-2F Stairs") emits light, the two center left light sensors 21a-5 and 21a-6 detect the light emission.

[0035] In this way, by grasping in advance the relationship (light emission detection relationship) between the light emission of the light-emitting unit 10a and the detection by the light sensor 21a according to the positional relationship between the light sensor 21a and the light-emitting unit 10a in the light sensor board 21c, it is possible to determine whether the detection of the light sensor 21a based on the driving of the detector 1 is normal or not, and generate a detection result. That is, for example, by using a certain light-emitting unit 10a as a reference and specifying the light sensors 21a that detect the light emission of each of the three light-emitting units 10a in total, including the light-emitting unit 10a adjacent in the horizontal direction (the light-emitting unit 10a adjacent in the horizontal direction) and the light-emitting unit 10a adjacent in the vertical direction (the light-emitting unit 10a adjacent in the vertical direction), it is possible to know which light sensor 21a reacts and detects each time the emitting light-emitting unit 10a is shifted by one in the horizontal and vertical directions. Therefore, prior to generating and transmitting the detection result (step S108), server 23 holds the light emission detection relationships associated with the light emissions of the three light-emitting units 10a described above, and generates the detection result by referring to these light emission detection relationships.

[0036] FIG. 18 is a flowchart showing the procedure for the server 23 to hold the light emission detection relationship. First, the user terminal 24 accepts the input of the light emission detection relationship (step S50). In step S50, the user terminal 24 displays a GUI (Graphical User Interface) including a GUI element 25 simulating the light sensor board 21c on the display unit, as shown in FIG. 19, for example. The GUI element 25 includes the same number of GUI selection elements 25a as the light sensors 21a on the light sensor board 21c in the same positional relationship. Each GUI selection element 25a can be selected by the worker 50, and the light sensor 21a (light emission detection relationship) that reacts when each of the at least three light emitting units 10a described above emits light can be specified by selecting the GUI selection element 25a. FIGS. 19 to 24 show the procedure for the worker 50 to input the light emission detection relationship by selecting the GUI selection element 25a through the GUI element 25. As shown in Figs. 19 and 20, the GUI first prompts the user to select a GUI selection element 25a corresponding to the optical sensor 21a that responds when a certain light-emitting unit 10a (for example, the uppermost left light-emitting unit 10a) emits light. Fig. 20 shows an example in which the two upper left GUI selection elements 25a (GUI selection elements 25a corresponding to the optical sensors 21a-1 and 21a-2 shown in Fig. 17) are selected. Next, as shown in Figs. 21 and 22, the GUI prompts the user to select a GUI selection element 25a corresponding to the optical sensor 21a that responds when the next light-emitting unit 10a in the horizontal direction emits light. Fig. 22 shows an example in which two GUI selection elements 25a in the upper middle (GUI selection elements 25a corresponding to the optical sensors 21a-3 and 21a-4 shown in Fig. 17) are selected. Next, as shown in Figs. 23 and 24, the GUI prompts the user to select a GUI selection element 25a corresponding to the optical sensor 21a that responds when the next light-emitting unit 10a in the vertical direction emits light. Fig. 24 shows an example in which the two GUI selection elements 25a on the left side (GUI selection elements 25a corresponding to the optical sensors 21a-5 and 21a-6 shown in Fig. 17) are selected. In this manner, the GUI is sequentially transitioned and the user terminal 24 receives input of the light emission detection relationship in at least three adjacent light-emitting units 10a described above.

[0037] The user terminal 24 transmits the received light emission detection relationship to the server 23 (step S51). The server 23 receives the light emission detection relationship (step S52) and stores it internally (step S53). This allows the server 23 to generate a detection result by referring to the stored light emission detection relationship every time it receives a detection signal from the light sensor 21a. That is, the light emission detection relationship allows it to estimate which light sensor 21a will react every time the light-emitting units 10a, which emit light one by one in the horizontal and vertical directions, are shifted, so that if the detection signal from the light sensor 21a matches the estimation, a positive detection result indicating that the light-emitting unit 10a has normally emitted light is output, and if it does not match, an error message is output.

[0038] The server 23 is composed of a computer such as a personal computer (PC) or a workstation. FIG. 25 is a block diagram showing an example of a schematic configuration of the server 23. The server 23 has a processor 231, a communication circuit 232, a storage unit 233, and a bus 234. The processor 231 executes various controls such as control of the communication circuit 232 and the storage unit 233 by executing computer program instructions. For example, the processor 231 generates a detection result based on a detection signal received via the communication circuit 232. The communication circuit 232 communicates with the communication unit 22 and the user terminal 24 via the network 2. The storage unit 233 is a memory or storage that stores various information, and stores, for example, a threshold value used for judging the light emission of the light-emitting unit 10a described with reference to FIGS. 6 to 8, the above-mentioned sensor installation information, an inspection status, a light emission detection relationship, and the like. The bus 234 interconnects various components in the server 23 and is used for mutual communication of data and information.

[0039] The user terminal 24 is configured with a portable computer such as a smartphone, tablet, or PC. FIG. 26 is a block diagram showing an example of a schematic configuration of the user terminal 24. The user terminal 24 has a processor 241, a communication circuit 242, a storage unit 243, an input unit 244, an output unit 245, and a bus 246. The processor 241 executes various controls such as control of the communication circuit 242, the storage unit 243, the input unit 244, and the output unit 245 by executing computer program instructions. For example, the processor 241 receives a detection result from the server 23 via the communication circuit 242 and controls the output of the detection result from the output unit 245, or controls the transmission of information input via the input unit 244 to the server 23 via the communication circuit 242. The communication circuit 242 communicates with the server 23 via the network 2. The storage unit 243 is a memory or storage that stores various information such as sensor installation information received from the server 23. The input unit 244 is an interface device that accepts input operations from a user, and is a keypad, buttons, etc. The output unit 245 outputs various information, and is composed of a speaker that outputs sound, a display that displays images, etc. The input unit 244 and the output unit 245 may be integrated to form a touch panel.

[0040] By configuring the inspection system 20 as described above, the worker 5 can inspect the light emitting operation of the light emitting unit 10a by a series of tasks: installing the detection unit 21 near the light emitting unit 10a of the fire alarm system 10, and patrolling the locations where the detectors 1 are installed with the detector driver 25 and the user terminal 24. This series of tasks can be performed by the worker 5 alone, simplifying the entire inspection process and reducing the number of people required.

[0041] The configuration of the inspection system 20 described above is an example, and various modifications are possible. For example, in the above-mentioned inspection system 20, the communication unit 22 transmits the detection signal of the detection unit 21 to the server 23, and the server 23, which receives the detection signal, determines whether to turn on the light-emitting unit 10a based on the detection signal. This configuration is not limited to the above, and the communication unit 22 may determine whether to turn on the light-emitting unit 10a based on the detection signal of the detection unit 21. In this case, the communication unit 21 includes a processor like the server 23, and executes the processing of steps S11 to S16, steps S21 to S26, or steps S31 to 36 based on the detection signal received from the detection unit 21. FIG. 27 is a flowchart showing the procedure for inspecting the light-emitting operation of the light-emitting unit 10a in the inspection system 20 of the modified example. In the modified example, when the detection result is output by the detection unit 21 (S105), the communication unit 22 that receives the detection signal performs the judgment process of steps S11 to S16, steps S21 to S26, or steps S31 to 36, and transmits a positive or negative detection result to the server 23 (S120). The server 23 receives the detection result from the communication unit 22 (S121) and transmits this detection result as is to the user terminal 24 (S122). Similarly, the user terminal 24 displays the detection result (S109 to S110), and the server 23 updates the inspection status (S110).

[0042] An example of the GUI displayed on the display unit of the user terminal 24 in steps S103 to S110 will be described in detail below. As shown in FIG. 28, the GUI includes an icon S1 corresponding to the light-emitting unit 10a to be inspected. The GUI may display the same number of icons S1 as the number of light-emitting units 10a provided in the fire alarm system 10. When the detection unit 21 is a plurality of optical sensors 21a, it is preferable to display the number of icons S1 corresponding to the number of optical sensors 21a. As shown in FIG. 28, the icons S1 are assigned numbers in sequence starting from 1 (in the example of FIG. 28, there are a total of 20 icons S1 from 1 to 20), and each assigned number may be displayed. It is preferable to display the same number of icons S1 as the number of light-emitting units 10a included in the sensor information received in S103.

[0043] Each icon S1 on the GUI notifies of light emission in association with the light emission of a specific light-emitting unit 10a. For this reason, the positions of each icon S1 and the light-emitting unit 10a are associated with each other. Specifically, when the detection unit 21 is a plurality of light sensors 21a, the communication unit 22 determines from which of the light sensors 21a attached to which light-emitting unit 10a the detection signal has been received. The communication unit 22 has a plurality of input terminals corresponding to the individual light sensors 21a, and each of the light sensors 21a is connected to one of the input terminals. A unique identifier is assigned to each input terminal in advance, and the light sensor 21a corresponding to a specific light-emitting unit 10a is connected to each input terminal by the user. As a result, the light-emitting unit 10a, the light sensor 21a, and the input terminal are associated with each other, and as a result, it is possible to determine from which light-emitting unit 10a the detection signal has been received by identifying the input terminal from which the detection signal has been received. For example, when a detection signal is received through input terminal #1, it can be detected that the detection signal has been received from the #1 optical sensor 21a corresponding to the #1 light-emitting unit 10a. The detection signal that the communication unit 22 transmits to the server 23 includes an identifier that identifies the light-emitting unit 10a that emitted light (i.e., an identifier that identifies the input terminal to which the optical sensor 21a that transmitted the detection signal is connected) (S106).

[0044] Furthermore, when the detection unit 21 is a camera 21b, the communication unit 22 determines which of the multiple light-emitting units 10a has emitted light by performing image recognition on the image captured by the camera 21b. The communication unit 22 identifies the position where the light-emitting action was detected in the captured image by image recognition, and determines which light-emitting unit 10a has emitted light according to this position. For example, it is preferable to register the positions of the multiple light-emitting units 10a on the fire alarm system 10, identify the position of the light-emitting unit 10a that has emitted light in the image captured by the camera 21b, and determine that the light-emitting unit 10a closest to this specified position has emitted light. The detection signal that the communication unit 22 transmits to the server 23 includes an identifier that identifies the light-emitting unit 10a that has emitted light (S106).

[0045] The positive detection result transmitted by the server 23 includes the identifier (the identifier for identifying the light-emitting unit 10a that emitted light) included in the detection signal received from the communication unit 22 (S108).

[0046] The user terminal 24 notifies the user of the light emission by using a specific icon S1 according to the identifier included in the positive detection result received from the server 23 (S109, S110). For this purpose, the identifier included in the detection result is associated with the icon S1 in advance in the user terminal 24. The user terminal 24 holds a table in which the identifier is associated with the number of the icon S1. FIG. 29 shows an example of the table T1 in which the identifier is associated with the number of the icon S1. Each icon S1 is associated with a unique identifier, and the user terminal 24 refers to the table T1 and notifies the user of the icon S1 with the corresponding number according to the identifier included in the detection result. In the example shown in FIG. 28, for example, if the detection result includes the identifier "003", this means that the light-emitting unit 10a corresponding to the identifier 003 has emitted light, and the notification of the light emission is made by using the icon S1 with the number "3" associated with the identifier 003.

[0047] The user terminal 24 may have a recovery notification function. The recovery notification function is a function for notifying that the light-emitting unit 10a that once emitted light has recovered from the light-emitting state. In other words, once the sensor 1 is operated using the sensor driver 25 to cause the corresponding specific light-emitting unit 10a to emit light, the sensor 1 continues to sense for a while, and the corresponding light-emitting unit 10a continues to emit light. After that, when the sensor 1 no longer senses, the corresponding light-emitting unit 10a goes out, and it becomes possible to perform another inspection. After transmitting a positive detection result including a specific identifier (S108), the server 23 monitors the reception state of the detection signal having the identifier for a certain period of time. While the server 23 continues to receive the detection signal having the identifier (S107), the light-emitting unit 10a corresponding to the identifier remains in the light-emitting state. When the server 23 does not receive a detection signal having the identifier within a certain period of time, the server 23 determines that the corresponding light-emitting unit 10a has been turned off, and transmits a detection signal (restoration detection signal) indicating that the light-emitting unit 10a has been restored from the light-emitting state to the user terminal 24 (S108). The restoration detection signal includes an identifier. When the user terminal 24 receives the restoration detection signal, it notifies the user terminal 24 of the restoration by using an icon S1 corresponding to the identifier included in the signal (S110). FIG. 30 is a diagram showing an example of a restoration notification in the user terminal 24. As shown in FIG. 30, the user terminal 24 changes the display mode of the icon S1 corresponding to the identifier indicated by the received restoration detection signal on the displayed GUI. In the example of FIG. 30, the word "Restored" is displayed on the icon S1.

[0048] In the GUI, each icon S1 may be configured to be selectable, and the selected icon S1 may be set according to the selection of an arbitrary icon S1. As shown in FIG. 31, a menu M1 associated with the selected icon S1 is displayed according to the selection of the icon S1. The menu M1 includes selectable menu buttons. In the example shown in FIG. 31, a menu button M11 for transmission setting, a menu button M12 for trouble setting, a menu button M13 for recovery notification setting, and a menu button M14 for disabling recovery notification are included. The transmitter setting menu button M11 is a menu button for setting the light-emitting unit 10a corresponding to the icon S1 as the light-emitting unit of the "transmitter". This is used in the case where the light-emitting unit 10a of the fire alarm system 10 does not emit light in response to the detection signal of the detector 1, but emits light in response to a transmission signal from a transmitter connected to the fire alarm system 10 separately from the detector 1, and the light-emitting unit is excluded from the inspection target. When the transmitter setting menu button M11 is selected, the light-emitting unit corresponding to the icon S1 is not treated as a detection of light-emitting. In response to the selection of the transmitter setting menu button M11, the icon S1 may be switched from displaying a number to displaying a "transmitter" as shown in FIG. 32 (in the example of FIG. 32, the icon S1 to which the number "3" was assigned is switched to displaying "H" indicating a transmitter). The trouble setting menu button M12 is a menu button for setting the light emitting unit 10a corresponding to the icon S1 as a "trouble occurrence" light emitting unit. This is used in the case where the light emitting unit 10a of the fire alarm system 10 does not emit light in response to the detection signal of the detector 1, but emits light when a trouble occurs in the fire alarm system 10 (for example, a break occurs in the connection line between the fire alarm system 10 and the detector 1), and is used for setting to exclude the light emission of this light emitting unit from the inspection target. When the trouble setting menu button M12 is selected, the light emission of the light emitting unit corresponding to the icon S1 is not treated as a light emission detection.In response to the selection of the trouble setting menu button M12, the icon S1 may be switched from displaying a number to displaying "trouble" as shown in Fig. 32 (in the example of Fig. 32, the icon S1 to which the number "15" was assigned is switched to displaying "T", indicating trouble). In this way, when the light-emitting unit 10a includes a light-emitting unit that is unrelated to the one that emits light in response to the detection signal of the sensor 1, such an unrelated light-emitting unit can be set on the GUI and excluded from the inspection target.

[0049] The recovery notification setting menu button M13 and the recovery notification disable menu button M14 are menu buttons for enabling or disabling (ON / OFF) the above-mentioned recovery notification function for the light-emitting unit 10a corresponding to the icon S1. When the recovery notification setting menu button M13 is selected in a state where the recovery notification function is disabled for the icon S1, the recovery notification function is enabled for the light-emitting unit 10a corresponding to the icon S1. When the recovery notification disable menu button M14 is selected in a state where the recovery notification function is enabled for the icon S1, the recovery notification function is disabled for the light-emitting unit 10a corresponding to the icon S1. When the recovery notification function is set to be disabled for the icon S1, the user terminal 24 transmits a recovery notification function stop signal to the server 23 to stop the recovery notification function. The recovery notification function stop signal includes an identifier corresponding to the icon S1. Upon receiving the recovery notification function stop signal, the server 23 does not transmit a recovery detection signal from the identifier included in the recovery notification function stop signal. In other words, the server 23 stops monitoring from the start of reception of a detection signal having the identifier until it is no longer received.

[0050] Modifications and extensions of the inspection system 20 will be described below. (1) Capture and send camera footage When transmitting the detection signal in step S108, the server 23 may transmit a camera image of the periphery of the light-emitting unit 10a of the fire alarm system 10 to the user terminal 24. When the camera 21b is used as the detection unit 21, the server 23 transmits to the user terminal 24 an image captured at the time when the server 23 recognizes the emission of the light-emitting unit 10a by image recognition based on the captured image of the camera 21b (S108). When the optical sensor 21a is used as the detection unit 21, a camera (separate camera) is connected to the server 23 in addition to the optical sensor 21a, and the periphery of the light-emitting unit 10a is arranged as an imaging range. The server 23 obtains an image captured at the time when the optical sensor 21a detects the emission of the light-emitting unit 10a from the separate camera, and transmits the image to the user terminal 24 (S108). For example, the fire alarm system 10 may be provided with a display that displays various information near the light-emitting unit 10a as shown in FIG. 33. In this case, it is preferable to include the display in the imaging range of the camera. The user terminal 24 may receive the captured image together with the detection signal (S109) and display the received captured image on the GUI (S110). (2) Contact output The server 23 may include an external interface for transmitting a control signal to an external facility device such as a broadcasting device, and may transmit a control signal from the external interface in response to receiving the detection signal in step S107 to operate the facility device. In this case, a contact output terminal may be made in response to receiving the detection signal in step S107. The external interface may be, for example, a contact output terminal having a contact using a mechanical relay or a semiconductor relay, and may be connected to a contact input terminal of the facility device. Alternatively, the external interface may be a wireless circuit conforming to standards such as wireless LAN or Bluetooth, and the facility device may also be similarly provided with a wireless circuit, so that a control signal is wirelessly transmitted from the server 23 to the facility device. The server 23 may also transmit a control signal from the external interface only when an identifier included in the detection signal received in step S107 is a predetermined identifier. Similarly, the communication unit 22 may also include an external interface for transmitting a control signal to an external facility device, and may transmit a control signal via the external interface in response to receiving a detection signal from the detection unit 21 to operate the facility device. In parallel with the output of the detection result in step S105, the communication unit 22 may transmit a control signal from the external interface. An example of the facility device is an emergency bell. As shown in FIG. 34, one end of an emergency bell 40 connected to the fire alarm system 10 may be connected to the communication unit 22, and the communication unit 22 may transmit a control signal to the emergency bell 40 to ring it upon light emission detection.
