[0004] [Patent Document 1] Patent No. 4437332 Summary of the Invention [Problem to be solved by the invention]

[0005] According to the system of Patent Document 1, the inspection history is displayed on the remote control, so that the inspector can be notified of an abnormality. However, the inspector obtains past abnormality information when he or she checks the site. Therefore, by the time the abnormality information is obtained, some time has passed since the occurrence of the malfunction, and there is a risk that the malfunction cannot be dealt with promptly. In addition, since preparations for repairs or part replacement cannot be made in advance, it is expected that it will take even more time to respond to the malfunction.

[0006] The present disclosure aims to provide a disaster prevention light inspection system that enables repairs or part replacement to be carried out early. [Means for solving the problem]

Effect of the Invention

[0008] According to the disaster prevention light inspection system of the present disclosure, it is possible to predict the timing of part replacement, and therefore repairs or part replacement can be carried out early. [Brief description of the drawings]

[0010] The disaster prevention light inspection system according to the present embodiment will be described with reference to the drawings. The same or corresponding components are designated by the same reference numerals, and the repeated description may be omitted.

[0011] Embodiment 1 FIG. 1 is a block diagram showing a configuration of a disaster prevention light inspection system 100 according to the first embodiment. The disaster prevention light inspection system 100 includes a disaster prevention lighting device 1 and an inspection terminal 2. The disaster prevention lighting device 1 is an emergency light or emergency lighting device installed in a facility. The emergency lighting device is also called an emergency light. Both the emergency light and the emergency lighting device are devices for enabling people to evacuate quickly and safely in the event of a fire or accident. The emergency light notifies people of an escape route or an evacuation route. The emergency lighting device provides the brightness necessary for evacuation.

[0012] The disaster prevention lighting device 1 lights up the light source 1c with power from the battery 1a in an emergency. The battery 1a is, for example, a secondary battery. The control unit 1d of the disaster prevention lighting device 1 is composed of one or more arithmetic devices such as a microcomputer, a CPU, a processor, etc. The control unit 1d controls the power supply circuit 1b to supply power from the battery 1a or a commercial power source to light up the light source 1c, which is the lighting unit.

[0013] In the emergency lighting device 1, the state of being supplied with power from a commercial power source during normal times continues, and the battery 1a is charged. Many emergency exit lights have the light source 1c turned on during normal times. In addition, many emergency lighting devices have the light source 1c turned off during normal times, but some are turned on as night lights during normal times. In both emergency exit lights and emergency lighting devices, when the power supply from the commercial power source is cut off due to a power outage caused by a disaster such as a fire or earthquake, the power supply source is switched from the commercial power source to the battery 1a. This allows the power circuit 1b of the emergency lighting device 1 to be supplied with the necessary power, and the light source 1c is maintained in a lit state. The emergency lighting device 1 must continue to have the light source 1c lit by the power supply from the battery 1a for a specified period or more. For this reason, regular inspection of the equipment is mandatory, and if there is a problem with the luminous flux of the light source 1c constituting the emergency lighting device 1, the capacity of the battery 1a, or the display regarding evacuation, repair or part replacement is required.

[0014] The disaster prevention lighting device 1 stores in the memory unit 1e individual product identification information of the disaster prevention lighting device 1 and operation information, which is data accumulated by the disaster prevention lighting device 1 during operation. The memory unit 1e can be configured with a memory such as a non-volatile memory. The memory unit 1e stores and manages the product manufacturer, product name, model number, manufacturing date, address, group information, etc. as product identification information. The memory unit 1e also stores and manages the cumulative operation time of the disaster prevention lighting device 1, the battery capacity of the battery 1a, failure history information, etc. as operation information.

[0015] The inspection terminal 2 is an operation terminal that can be carried by a user, such as a smartphone, a tablet terminal, etc. The inspection terminal 2 has, for example, a communication unit 2a, a control unit 2b, a display unit 2c, and a storage unit 2d. The inspection terminal 2 may be a remote control. The communication unit 2a of the inspection terminal 2 communicates with the disaster prevention lighting device 1 by wireless signals in response to a user's operation while an installed app or the like is running. For example, Bluetooth (registered trademark) can be used as a means of wireless communication. For example, one inspection terminal 2 is connected to multiple disaster prevention lighting devices 1. The user arbitrarily selects one of the multiple disaster prevention lighting devices 1 using the inspection terminal 2. As a result, data is transmitted and received between the selected disaster prevention lighting device 1 and the inspection terminal 2.

[0016] When using Bluetooth (registered trademark), the disaster prevention lighting device 1 transmits a beacon during operation. As a result, the inspection terminal 2 obtains device IDs, which are assigned to each disaster prevention lighting device 1 at the time of shipment, from the multiple disaster prevention lighting devices 1, and manages them in a list. The device IDs are composed of numbers, letters, symbols, etc., for example. In addition, the inspection terminal 2 and the disaster prevention lighting device 1 may communicate with each other using a method that uses radio waves in the 2.4 GHz band, known as Bluetooth Low Energy. As a result, compared to infrared communication, the inspection terminal 2 can communicate with disaster prevention lighting devices 1 over a wide range, and can obtain a lot of information related to maintenance in a short time.

[0017] In addition, the user can change the lighting state of the disaster prevention lighting device 1 corresponding to the selected device ID by selecting the acquired device ID and performing a confirmation operation using the inspection terminal 2. This allows the installation position of the disaster prevention lighting device 1 corresponding to the selected device ID to be collated.

[0018] In addition, the user can arbitrarily set an address as a unique identification number in order to manage multiple disaster prevention lighting devices 1. By arbitrarily setting an address, the disaster prevention lighting devices 1 can be managed with simple numerical values ​​such as integers. In addition, by setting an arbitrary number to the disaster prevention lighting devices 1 according to the equipment layout drawing, etc., a setting environment that is easy for the inspector or facility manager to understand can be constructed. In addition, by grouping and managing multiple disaster prevention lighting devices 1, the data held in the inspection terminal 2 can be organized according to the grouping of each floor, layout, etc., making it easier for the manager to manage.

[0019] In this embodiment, when a periodic inspection of the disaster prevention lighting device 1 is performed, the communication unit 2a of the inspection terminal 2 acquires product identification information of the disaster prevention lighting device 1, and the control unit 2b collates the target device based on the product identification information. The communication unit 2a also acquires operation information of the disaster prevention lighting device 1.

[0020] Regarding the accumulated operation time of the operation information, the disaster prevention lighting device 1 measures the operation time since the device was installed, and periodically stores the measured time in the storage unit 1e.

[0021] Regarding the battery capacity among the operating information, the minimum capacity when the battery 1a is fully charged is stipulated depending on the type of product. However, individual differences occur in the battery capacity due to the number of times it is charged and discharged, deterioration over time, etc. For this reason, the control unit 1d of the disaster prevention lighting device 1 calculates the capacity when it is fully charged. There are methods for calculating the battery capacity from the measured value of the internal resistance or the battery voltage. The control unit 1d of the disaster prevention lighting device 1 may automatically measure the battery capacity periodically, or may measure it when a monitor signal is received from the inspection terminal 2.

[0022] Regarding the fault history information among the operating information, if the control unit 1d of the disaster prevention lighting device 1 detects an abnormality in the electronic circuit or light source 1c during operation, or if the battery capacity falls below a preset threshold, the control unit 1d stores the event that has occurred together with date and time information in the memory unit 1e.

[0023] When a monitor signal is sent from the communication unit 2a of the inspection terminal 2 to the disaster prevention lighting device 1 by wireless communication, the disaster prevention lighting device 1 responds with the accumulated operating information as response data. When the communication unit 2a of the inspection terminal 2 acquires the operating information, the control unit 2b displays the acquired data on the display unit 2c and stores the acquired data in the memory unit 2d. The display unit 2c is, for example, a display screen. The memory unit 2d can be configured with, for example, a memory such as a non-volatile memory.

[0024] The control unit 2b of the inspection terminal 2 may estimate the distance to the disaster prevention lighting device 1 based on the radio wave strength of the signal received from the disaster prevention lighting device 1. Radio wave strength is also called RSSI (Received Signal Strength Indicator). When the control unit 2b estimates the distance from the inspection terminal 2 to the disaster prevention lighting device 1 based on the radio wave strength of the received wireless signal, it causes the display unit 2c to display the distance.

[0025] This allows the user to estimate the distance to each disaster prevention lighting device 1 and the relative positions of the multiple disaster prevention lighting devices 1. In other words, the installation location of the device can be guessed, making it possible to improve the efficiency of the task of identifying the device. Even if it is not possible to obtain accurate position information of the multiple disaster prevention lighting devices 1, it is possible to search for devices installed in places that cannot be seen with the naked eye during inspection by estimating the relative distances.

[0026] The control unit 2b may also estimate the time to replace parts of the disaster prevention lighting device 1 based on the history of operation information of the disaster prevention lighting device 1. This history of operation information is, for example, battery capacity data of the battery 1a received multiple times from the disaster prevention lighting device 1. The control unit 2b creates a decay curve of the battery capacity based on, for example, the battery capacity data and information on the date and time of inspection. By creating the decay curve in a graph, it is possible to predict the tendency of the battery capacity to decay in the future and the time when the battery capacity will decrease to an arbitrary threshold value due to continued operation and parts will need to be replaced. In this way, the control unit 2b may estimate the time to replace the battery 1a from the decay curve.

[0027] Furthermore, the control unit 2b may cause the display unit 2c to display information related to the timing of replacement of parts such as the battery 1a. For example, the control unit 2b causes the screen of the display unit 2c to display a graph showing a decay curve of the battery capacity, and displays the date and time when replacement of parts is required due to a decrease in battery capacity.

[0028] The threshold value for the control unit 2b to determine whether or not a part needs to be replaced may be set in advance in an application or the like of the inspection terminal 2. In addition, the threshold value may be determined in advance based on the product identification information of the disaster prevention lighting device 1.

[0029] In this way, according to the disaster prevention light inspection system 100 of this embodiment, the timing of parts replacement can be estimated based on the operation information history. Therefore, repairs or parts replacement can be carried out early. Also, parts can be replaced with normal parts before a periodic inspection results in a failure. Furthermore, by estimating the timing of parts replacement, replacement parts can be prepared in time for, for example, a periodic inspection. Therefore, parts can be replaced at the time of inspection, rather than failing the inspection and having to perform the replacement work again at a later date. Therefore, work efficiency can be improved.

[0030] The part for which replacement time is estimated is not limited to the battery. The control unit 2b may estimate the replacement time of other parts of the disaster prevention lighting device 1 by using the history of operation information other than the battery capacity.

[0031] Moreover, at the time of inspection, the inspection results acquired on the day are displayed on the inspection terminal 2, so that the inspector can understand the results. Furthermore, the control unit 2b may create a report using the data acquired from the disaster prevention lighting device 1 and a predetermined format. Specifically, the control unit 2b creates a report using information such as product identification information, operation information, past inspection data, and failure prediction information of the disaster prevention lighting device 1, using a predetermined format. The failure prediction information is, for example, a calculated attenuation curve or a time to replace parts.

[0032] Conventionally, inspectors would compile inspection results, convert them into a report in a specified format, and then submit the report to a specified destination. In contrast, in this embodiment, inspection results are automatically entered into a pre-registered report format and saved as electronic data. The destination to which the report is to be submitted, the name of the facility to be inspected, the inspector's name, ID, etc. are arbitrarily set in advance in the inspection terminal 2. This allows users to quickly submit reports to clients, etc., without having to edit documents.

[0033] In addition, there are cases where the inspection work and confirmation of the results must be performed by a qualified person. For this reason, a mechanism for acquiring and authenticating the ID of the inspector or the person who approves the inspection results when creating or confirming a report may be introduced into the disaster prevention light inspection system 100.

[0034] Furthermore, the control unit 2b may change the layout of information displayed on the display unit 2c according to the priority of information displayed on the display unit 2c, such as operation information, inspection results for the day, past inspection results, and failure prediction information. For example, high-priority information, such as failure information that requires immediate repair or replacement, is displayed in an easy-to-see position, such as the center of the screen. Furthermore, high-priority information may be displayed larger by changing the color or size of the characters or figures.

[0035] Similarly, when creating the above-mentioned report, the control unit 2b may change the layout of the report according to the priority of information to be described in the report, such as operation information, inspection results for the day, past inspection results, and failure prediction information. Specifically, the display position, color, or size of characters or figures is appropriately changed according to the priority. This allows the user to intuitively grasp important issues.

[0036] The control unit 2b may also search for information on parts that need to be replaced via the Internet 3 based on the estimated timing of part replacement or the inspection results. In this case, the control unit 2b automatically searches for and acquires information on parts to be replaced from the product manufacturer's website or the database of the management system based on information such as the product manufacturer and model number acquired as product identification information from the disaster prevention lighting device 1. The control unit 2b further displays information on the searched parts on the display unit 2c of the inspection terminal 2 and notifies the user.

[0037] The control unit 2b may store the inspection results or the automatically generated report in the server 4 via the communication unit 2a. The server 4 is, for example, a cloud server. This allows the inspection results or the report to be made available to related parties other than the inspector. The control unit 2b may also store information on the searched parts in the server 4 via the communication unit 2a. This allows the facility manager 6 or parts distributor 5 who shares the information on the server 4 to understand the necessity of part replacement and information on the parts to be replaced together with the inspection results. The server 4 may also store product identification information acquired from the disaster prevention lighting device 1 during inspection or estimated failure prediction information.

[0038] For example, the server 4 may be accessible only to specific users. For example, the stored data may be protected by a means such as requiring authentication to access the server 4. For example, in addition to the inspector, an ID with the right to access the server 4 may be given to the owner of the facility where the disaster prevention lighting device 1 is installed, the facility manager 6, the product manufacturer, the parts distributor 5, the maintenance company 7, and the like.

[0039] In addition, by sharing the information on the need for part replacement or the searched part, it is assumed that, for example, the facility manager 6 will make various arrangements for carrying out the part replacement. These arrangements include purchasing and shipping the parts, and requesting the maintenance company 7 to perform the work. In the disaster prevention light inspection system 100 of this embodiment, parts that need to be replaced based on a prediction of the time to replace the parts or the inspection results, or parts searched for via the Internet 3, may be automatically ordered. This reduces the effort required for arranging parts, and makes it possible to quickly arrange parts in a short period of time.

[0040] For example, if the report indicates that a part needs replacing, an order is automatically placed with the parts distributor 5 to purchase the replacement part. The order may be placed by the server 4 or by the control unit 2b of the inspection terminal 2. The replacement part is then shipped to the facility manager 6 or maintenance company 7. For payment procedures, the inspection terminal 2 or server 4 registers in advance information such as a bank account from which the payment will be made, a payment method such as a credit card, and identification information. Depending on the estimated time for part replacement or the registration of the inspection results, the order, shipment, and delivery are quickly placed, allowing the replacement work to be carried out promptly at the target facility.

[0041] 2 is a flowchart showing the process when the disaster prevention lighting device 1 according to the first embodiment is installed. First, power is supplied to the disaster prevention lighting device 1 to start the disaster prevention lighting device 1 (step 1). In this state, an inspection tool such as an app installed in the inspection terminal 2 is started (step 2). The disaster prevention lighting device 1 periodically transmits a beacon via wireless communication. The inspection terminal 2 receives the beacon via wireless communication (step 3), thereby recognizing the communication partner and establishing a wireless network with the disaster prevention lighting device 1.

[0042] The person who sets the device performs an operation to obtain the device ID by operating buttons on the screen of the inspection terminal 2 (step 4). This causes the inspection terminal 2 to broadcast a monitor command for the device ID on the wireless network. The disaster prevention lighting device 1 that receives the monitor command transmits a response signal whose data is the device ID. At this time, multiple disaster prevention lighting devices 1 may transmit response signals. When the inspection terminal 2 receives the response signal (step 5), it displays the obtained device ID on the screen (step 6). If there are multiple response signals, the inspection terminal 2 displays the multiple device IDs in a list (step 6).

[0043] At this time, the inspection terminal 2 may measure and display the radio wave strength of the wireless signal, or may display data on the distance estimated from the radio wave strength (step 6). The inspection terminal 2 may measure the radio wave strength when receiving the wireless signal. Also, the inspection terminal 2 may grasp the radio wave strength by adding data on the radio wave strength measured when the disaster prevention lighting device 1 receives a monitor command to the response signal. Also, the inspection terminal 2 may sort the received multiple device IDs in order of strongest or weakest radio wave strength and list them.

[0044] From the multiple device IDs and radio wave strength, the setter can grasp the approximate distances and relative positional relationships from the inspection terminal 2 of the multiple disaster prevention lighting devices 1. This allows the setter to, for example, narrow down the devices to be set in subsequent work, grasp the existence of devices whose installation positions cannot be confirmed, and estimate the approximate distances and positions.

[0045] In order to compare the acquired device ID with the installed disaster prevention lighting devices 1, the setter selects any one of the acquired device IDs on the screen and performs an operation check operation (step 6). As a result, a command for selection confirmation is sent to the selected device ID by wireless signal. The disaster prevention lighting device 1 having the corresponding device ID performs an operation such as blinking the light source 1c or a light and dark operation in response to the operation check command (step 7). This allows the setter to identify the disaster prevention lighting device 1 corresponding to the selected device ID.

[0046] After identifying the target device, the setter performs an operation to acquire the product identification information on the screen of the inspection terminal 2 (step 8). As a result, a monitor command is sent by wireless communication to the target disaster prevention lighting device 1, and the target disaster prevention lighting device 1 transmits the product identification information as response signal data. Such information acquisition operation may be performed by the setter for each target device, or may be automatically performed continuously for multiple devices. The acquired product identification information is displayed on the screen of the inspection terminal 2 and stored in the memory unit 2d.

[0047] Next, the setter assigns the address shown on the facility drawing in advance or an address determined arbitrarily to the acquired device ID (step 9). The setter sends an address setting command by wireless communication to the target device ID. The address is, for example, composed of integers, and is preferably a simple number that is easy for the setter to understand. In addition to the address for identifying each device during inspection, a group number that groups together multiple addresses can also be set. By setting the group number, it is possible to narrow down the devices to communicate in advance among multiple disaster prevention lighting devices 1 installed. In other words, by selecting a group and controlling it, it is possible to make only the disaster prevention lighting devices 1 to which the specified group number is assigned respond. The disaster prevention lighting device 1 that receives the address setting command or group number setting command stores the address or group number in the storage unit 1e. This completes the setting of the address and group (step 10). Note that the process at the time of installation of the disaster prevention lighting device 1 according to the first embodiment may be a process in which the address is not assigned in step 9 and the device ID is used instead.

[0048] 3 is a flowchart showing a process of acquiring and displaying failure prediction information according to the first embodiment. When inspecting the disaster prevention lighting device 1, the inspector starts the application of the inspection terminal 2 (step 21). The inspector selects any disaster prevention lighting device 1 to be inspected by specifying the set address or group on the screen of the inspection terminal 2, and performs a connection confirmation operation (step 22). When the inspection terminal 2 and the disaster prevention lighting device 1 to be inspected can normally communicate by wireless communication, the inspection terminal 2 displays that fact on the screen, and the inspector grasps the result (step 23).

[0049] Next, when the inspector wants to check the battery capacity, for example, he or she performs a battery capacity monitor operation on the screen of the inspection terminal 2 (step 24). This causes a monitor command to be transmitted from the inspection terminal 2 via wireless communication. In addition to the battery capacity, a monitor command may be transmitted to obtain information such as accumulated operating time or component failure information to be checked by the inspector. An operating method may be provided that allows a series of such information to be obtained all at once.

[0050] The disaster prevention lighting device 1 that has received the battery capacity monitor command measures or calculates the capacity of the battery 1a installed inside and transmits a response signal to the inspection terminal 2 (step 25). The disaster prevention lighting device 1 may periodically measure or calculate and store the capacity of the battery 1a, and immediately respond with the latest stored data when the monitor signal is received.

[0051] The inspection terminal 2 displays the received battery capacity data on the screen. Furthermore, the inspection terminal 2 creates a decay curve by combining the battery capacity data received during past inspections with date and time information and graphing the change in battery capacity, and displays the decay curve on the screen (step 26). It may be possible to select whether to display only the current data or the decay curve by an operation on the screen. The decay curve includes not only the past battery capacity transition but also data predicting how the battery capacity will change in the future. For example, a threshold value is set for the battery capacity to determine battery failure. The inspection terminal 2 calculates the time when the battery capacity will be less than a certain capacity, and displays date information, etc. (step 26). The decay curve may be calculated, for example, by artificial intelligence using information on the parts used, accumulated learning data, etc. Note that the process of acquiring and displaying the failure prediction information according to the first embodiment may be a process of specifying a device ID instead of specifying an address in step 22.

[0052] FIG. 4 is a flowchart showing a process of creating a report according to the first embodiment. The process up to step 26 is the same as the process shown in FIG. 3. Next, the inspector performs a report creation operation on the screen of the inspection terminal 2 (step 30). As a result, the inspection terminal 2 writes the data acquired from the disaster prevention lighting device 1 and the failure prediction information in a predetermined format registered in advance for reporting (step 31). The predetermined format is designated in advance, for example, by the facility manager or the facility owner. The report also includes the name of the facility, information on the target floor, information on the report destination, and the like. The report may also include information on parts that need to be replaced due to insufficient battery capacity or a failure. The electronic file of the report created on the inspection terminal 2 is stored in the storage unit 2d of the inspection terminal 2, and is submitted to the report destination by e-mail transmission, printing, or the like, and is utilized.

[0053] Fig. 5 is a flow chart showing a process of automatically searching for parts information according to the first embodiment. The process up to step 26 is the same as the process shown in Fig. 3. If it is determined based on the failure prediction information that replacement of the part is not necessary (No in step 40), no process is performed (step 41). If it is determined based on the failure prediction information that replacement of the part is necessary (Yes in step 40), the inspection terminal 2 searches the Internet 3 for information on parts that need to be replaced due to insufficient battery capacity or a failure, based on the product identification information stored in advance (step 43). The information source to be searched is a catalog or a dedicated database of the target product or parts manufacturer.

[0054] The inspection terminal 2 notifies the inspector of the searched parts information by displaying it on the screen (step 44). The inspector can then make arrangements to purchase the parts after checking the display results. As a procedure for searching for parts information, the search may be started by the inspector operating the screen (step 42). Alternatively, the inspection terminal 2 may automatically perform the search process when it acquires the failure prediction information.

[0055] Fig. 6 is a flowchart showing the process of information disclosure by the server 4 according to the first embodiment. The processes of steps 21 to 26, steps 30 to 31, and steps 40 to 44 are similar to the processes shown in Figs. 3 to 5. The server 4 is used as a means for sharing the report created in step 31. For example, if a server 4 managed by the facility manager 6 or the product manufacturer is prepared and information about the equipment or products is shared on the server 4, a part of the server 4 may be used. If the server 4 has not been prepared in advance, a server 4 may be constructed for sharing information about the inspection results.

[0056] The inspector performs an operation to save the report to the server 4 on the screen of the inspection terminal 2 (step 50). This connects the inspection terminal 2 to the Internet 3, and the report is saved in a specified server 4 (step 51). After that, for example, the facility manager 6 can request an information inquiry from the server 4 (step 52) and obtain the report as information (step 53). The report may also include information on parts that need to be replaced due to insufficient battery capacity or a malfunction.

[0057] The facility manager 6 who has checked the report can report the inspection results to, for example, the facility owner or a national institution. The facility manager 6 can also arrange for parts that need to be replaced and request the maintenance company 7 to perform the work. The process of saving the report to the server 4 may be performed automatically without the inspector performing any operation on the screen of the inspection terminal 2. The server 4 may be used not only to share reports or inspection results, but also to share information related to the installation or operation of products, to share apps used during inspection, to share information related to maintenance, and the like.

[0058] Fig. 7 is a flow chart showing the process of automatic ordering of parts according to the first embodiment. The process up to step 51 is the same as the process shown in Fig. 6. If part replacement is necessary (Yes in step 60) and, for example, the facility manager 6 has set up automatic ordering of parts in advance (Yes in step 62), order information for purchasing parts is transmitted from the server 4 to the parts distributor 5 (step 63). If part replacement is not necessary (No in step 60) or automatic ordering of parts has not been set (No in step 62), the order process is not carried out (step 61).

[0059] The order information data includes, for example, the delivery destination, the model number of the target part, the order quantity, the desired delivery date, and the like. When the parts distributor 5 receives the order information, it dispatches the target part included in the order information data (step 64). The maintenance company 7 receives the parts dispatched from the parts distributor (step 65) and replaces the parts in the disaster prevention lighting device 1 of the target facility (step 65). Note that dispatch from the parts distributor 5 may also be performed automatically.

[0060] The process flow explained so far is an example, and a flow may be configured by combining some of the above processes. In addition, the process in which the setter or inspector operates the inspection terminal 2 and the procedure performed by the facility manager 6 or parts distributor 5 may be performed automatically, or may be applied to minimize opportunities for human involvement and to speed up the process.

[0061] In this embodiment, the control unit that estimates the time to replace parts has been described by taking the control unit 2b of the inspection terminal 2 as an example. However, the control unit may be provided in any PC, controller, etc. that controls the disaster prevention lighting device 1, or may be provided in the server 4. The control unit may be configured with one or more arithmetic devices such as a microcomputer, a CPU, a processor, etc. The control unit may realize its function by executing a program in the arithmetic device.
