[Embodiment]
<Configuration of lighting system>
Drawing 1 is a figure showing the example of composition of the lighting system concerning an embodiment. In FIG. 1, the lighting system 100 includes emergency lighting devices 10A, 10B, 10C, 10D, and 10E, a terminal 20, and a server 30. The terminal 20 is a portable terminal possessed by an inspector of the emergency lighting devices 10A, 10B, 10C, 10D, and 10E. For example, the terminal 20 is a portable terminal such as a smartphone or a tablet terminal. In the state shown in FIG. 1, the emergency lighting device 10A is a “master”, and the emergency lighting devices 10B, 10C, 10D, and 10E are “slave”.

  The emergency lighting devices 10A, 10B, 10C, 10D, and 10E are installed at predetermined intervals in the facility. For example, the emergency power supply 4 is used in an emergency such as when a disaster occurs or the commercial power supply 40 is lost. Illuminate the inside of the facility. Each of the emergency lighting devices 10A, 10B, 10C, 10D, and 10E is assigned an “illuminating device ID” that can uniquely identify each. The emergency lighting device 10A includes an emergency lamp 1A and a wireless communication module 2A. The emergency lighting device 10B includes an emergency lamp 1B and a wireless communication module 2B. The emergency lighting device 10C includes an emergency lamp 1C and a wireless communication module 2C. The emergency lighting device 10D includes an emergency lamp 1D and a wireless communication module 2D. The emergency lighting device 10E includes an emergency lamp 1E and a wireless communication module 2E. The emergency lighting devices 10A, 10B, 10C, 10D, and 10E have the same configuration.

  For example, between the wireless communication module 2A and each of the wireless communication modules 2B, 2C, 2D, and 2E, wireless communication C11, C12, C13, and C14 is performed by a communication method according to the ZigBee (registered trademark) standard. . On the other hand, wireless communication C2 is performed between the wireless communication module 2A and the terminal 20 by a communication method according to the BLE (Bluetooth (registered trademark) Low Energy) standard. The wireless communication modules 2A to 2E have both a communication function according to the ZigBee standard and a communication function according to the BLE standard. In addition, wireless communication C3 is performed between the terminal 20 and the server 30 by a communication method according to the Wi-Fi standard.

  Hereinafter, the emergency lighting devices 10A to 10E are described as “emergency lighting device 10” when they are not particularly distinguished. Hereinafter, the emergency lamps 1 </ b> A to 1 </ b> E will be referred to as “emergency lamp 1” when they are not particularly distinguished. Hereinafter, the wireless communication modules 2 </ b> A to 2 </ b> E are described as “wireless communication module 2” when they are described without distinction.

  In the following description, an example in which wireless communication is performed between the wireless communication module 2A and each of the wireless communication modules 2B, 2C, 2D, and 2E will be described, but the embodiment is not limited thereto. Absent. For example, each of the wireless communication modules 2A to 2E may perform hopping of wireless communication. For example, when the wireless communication module 2C cannot directly communicate with the wireless communication module 2A due to factors such as the installation positions of the emergency lighting devices 10A to 10E, the wireless communication module 2C passes through the wireless communication module 2D that can directly communicate with the wireless communication module 2A. Then, communication with the wireless communication module 2A may be performed.

<Configuration and operation of emergency lighting device>
FIG. 2 is a diagram illustrating a configuration example of the emergency lighting device according to the embodiment. In FIG. 2, the emergency lighting device 10 includes an emergency lamp 1, a wireless communication module 2, a control unit 3, an emergency power supply 4, an inspection unit 5, and a storage unit 6. The emergency lighting device 10 is connected to a commercial power source 40. Hereinafter, operations common to both the emergency lighting device as a master and the emergency lighting device as a slave will be described.

  The emergency lamp 1 is lit when at least power supply by the commercial power supply 40 is stopped.

  The emergency power supply 4 is a storage battery (secondary battery) that supplies power to the emergency lamp 1 when power supply from the commercial power supply 40 is stopped. The emergency power supply 4 can be charged via the control unit 3 when the commercial power supply 40 supplies power.

  The control unit 3 charges the emergency power supply 4 with the commercial power supply 40 at all times other than the emergency, and turns on the emergency lamp 1 with the emergency power supply 4 in an emergency. The control unit 3 always operates the wireless communication module 2, the inspection unit 5, and the storage unit 6 with the commercial power supply 40. The control unit 3 may operate the wireless communication module 2 with the commercial power supply 40 at all times and the emergency power supply 4 in an emergency.

  The wireless communication module 2 performs wireless communication with another wireless communication module 2 or the terminal 20 by wireless communication in a bidirectional mode.

  The inspection unit 5 performs a predetermined inspection of the emergency power supply 4 at a constant inspection cycle. The inspection unit 5 calls the inspection for judging the abnormality of the emergency power supply 4 (hereinafter sometimes referred to as “abnormality inspection”) as a predetermined time defined in the law (hereinafter referred to as “the legal predetermined time”). Only do). In addition, the inspection unit 5 sets a predetermined period (hereinafter, sometimes referred to as “the legal period”) as stipulated by law as the first inspection cycle, and this time when the legal period has elapsed since the previous abnormal inspection. Check for abnormalities. That is, the inspection unit 5 performs an abnormal inspection periodically for a predetermined period of time according to a predetermined period of law. In the following, an abnormal inspection that is periodically performed for a predetermined period of time in accordance with a predetermined period of the law may be referred to as “regular periodical inspection”.

  Further, the inspection unit 5 performs an inspection for diagnosing the state of the emergency power supply 4 (hereinafter sometimes referred to as “state diagnosis inspection”) for a predetermined time shorter than the legal predetermined time (hereinafter referred to as “predetermined short time”). ”). In addition, the inspection unit 5 uses a predetermined period shorter than the legal predetermined period (hereinafter, sometimes referred to as “predetermined short period”) as the second inspection period, and when the predetermined short period has elapsed since the previous state diagnosis inspection. At this time, the condition diagnosis inspection will be performed. That is, the inspection unit 5 performs state diagnosis inspection periodically for a predetermined short period according to a predetermined short period. In the following, a state diagnosis inspection that is periodically performed for a predetermined short period according to a predetermined short period may be referred to as a “short-time inspection”.

  In this way, the inspection unit 5 performs a regular inspection in the first inspection cycle and a short inspection in a second inspection cycle that is shorter than the first inspection cycle. In the following, when explaining regular inspections and short-term inspections without distinction, they are simply referred to as “inspection”.

  For example, the inspection unit 5 inspects the emergency lighting device 10 by detecting the voltage, current, temperature, discharge time, and number of discharges of the emergency power supply 4, and the lighting device ID, the inspection date and time, and the detected voltage. , Current, temperature, discharge time, and number of discharges are associated with each other and output to the storage unit 6 as inspection results. Further, for example, the inspection unit 5 turns on the emergency lamp 1 using power supplied from the emergency power supply 4 for a predetermined short time (for example, about 15 seconds) in the short time inspection, and before and after the lighting, The voltage and current values supplied by the power supply 4 may be stored in the storage unit 6 as the inspection result. For example, even if the lighting is performed for a short time of about 15 seconds, the change in the value of the supply voltage and the supply current from the emergency power supply 4 before and after the lighting is due to the deterioration of the emergency power supply 4 and the detection and replacement timing of defective products. It can be used for state diagnosis inspection such as prediction of In addition, it is preferable that the time per inspection of the emergency power supply 4 by the inspection unit 5 is set to the minimum time within the design allowable range.

  The storage unit 6 stores the inspection result input from the inspection unit 5. For example, the storage unit 6 stores the inspection results in time series. Since the capacity of the storage unit 6 is limited, for example, the storage unit 6 may store only inspection results for three years retroactively from the current date and time.

  The wireless communication module 2 wirelessly transmits the inspection result input from the inspection unit 5.

  In order to prevent the emergency lamp 1 from being turned on when the inspection unit 5 or the wireless communication module 2 operates in the short-time inspection, the emergency lighting device 10 is used when the short-time inspection is performed. You may have the pseudo load through which only current flows. Since the emergency lighting device 10 has a pseudo load, a current flows to the pseudo load instead of the emergency lamp 1 when the inspection unit 5 or the wireless communication module 2 operates in a short-time inspection. When the inspection is performed for a short time, the emergency lamp 1 is not turned on because a current flows to the pseudo load instead of the emergency lamp 1. The pseudo load is disposed in the wireless communication module 2, for example.

<Slave operation>
Next, a specific operation of the emergency lighting device as a slave will be described. The inspection unit 5 of the emergency lighting devices 10B, 10C, 10D, and 10E, which are slaves, acquires the inspection results stored in the storage unit 6 at a constant report cycle and outputs the results to the wireless communication module 2. For example, when the inspection cycle is “1 day”, “1 month” is set in the inspection unit 5 as a reporting cycle longer than the inspection cycle, and the inspection unit 5 uses the predetermined date and time of each month as the reporting date and time. The check result for one month (for example, if the report date and time is 10:00 am on the first day of every month) is acquired from the storage unit 6 and output to the wireless communication module 2. At this time, the inspection unit 5 sets the transmission destination of the inspection result as the emergency lighting device 10A that is the master. That is, each of the wireless communication modules 2B to 2E transmits the inspection result of one month in each of the emergency lighting devices 10B to 10E to the wireless communication module 2A at a predetermined date every month.

<Master operation>
Next, a specific operation of the emergency lighting device as a master will be described. The wireless communication module 2A of the emergency lighting device 10A that is the master receives the inspection results for one month transmitted from the wireless communication modules 2B, 2C, 2D, and 2E of the emergency lighting devices 10B, 10C, 10D, and 10E, respectively. Then, the received inspection result for one month is output to the inspection unit 5. The inspection unit 5 stores the inspection results in the emergency lighting devices 10B, 10C, 10D, and 10E in the storage unit 6 together with the inspection results in the emergency lighting device 10A (that is, the own device). That is, the inspection unit 5 collects the inspection results of all the emergency lighting devices of the emergency lighting devices 10A to 10E and stores them in the storage unit 6. When the inspection unit 5 receives the inspection result acquisition request from the terminal 20 via the wireless communication module 2A, the inspection unit 5A stores all the inspection results stored in the storage unit 6, that is, the emergency lighting devices 10A to 10E. The inspection result in the emergency lighting device is acquired and output to the wireless communication module 2. At this time, the inspection unit 5 acquires the inspection result of the inspection date and time corresponding to the “acquisition target period” included in the inspection result acquisition request from the terminal 20 and outputs it to the wireless communication module 2. At this time, the inspection unit 5 sets the transmission destination of the inspection result as the terminal 20.

<Terminal operation>
The terminal 20 transmits an inspection result acquisition request including the acquisition target period to the master emergency lighting device 10A according to the operation of the inspector, and is transmitted from the emergency lighting device 10A according to the inspection result acquisition request. The inspection results (that is, the inspection results of all the emergency lighting devices 10A to 10E) are received. Then, the terminal 20 transmits the inspection result received from the emergency lighting device 10A to the server 30.

  Note that the terminal 20 may automatically transmit an inspection result acquisition request when entering the range of a predetermined distance from the emergency lighting device 10A that is the master. Further, the terminal 20 may temporarily store the inspection result received from the emergency lighting device 10A in the memory of the terminal 20, and transmit the inspection result stored in the memory to the server 30 according to the operation of the inspector. .

<Server configuration and operation>
FIG. 3 is a diagram illustrating a configuration example of a server according to the embodiment. In FIG. 3, the server 30 includes a wireless communication module 31, an analysis unit 32, and a storage unit 33.

  The wireless communication module 31 receives the inspection result transmitted from the terminal 20 (that is, the inspection result in all emergency lighting devices of the emergency lighting devices 10 </ b> A to 10 </ b> E) and outputs it to the analysis unit 32. The analysis unit 32 stores the inspection result input from the wireless communication module 31 in the storage unit 33.

  Further, the analysis unit 32 analyzes the inspection result stored in the storage unit 33 for each lighting device ID and determines the deterioration state of each emergency power source 4 of the emergency lighting devices 10A, 10B, 10C, 10D, and 10E. The determination result is output to the wireless communication module 31. The wireless communication module 31 transmits the determination result by the analysis unit 32 to the terminal 20 and notifies the terminal 20. The terminal 20 receives the determination result by the analysis unit 32 and displays it on the touch panel of the terminal 20. At this time, the determination result by the analysis unit 32 is displayed on the touch panel of the terminal 20 for each lighting device ID.

  For example, the analysis unit 32 determines each emergency lighting device 10A, 10B, 10C, 10D, 10E based on at least one of voltage, current, temperature, discharge time, and number of discharges included in the inspection result. The deterioration state of the power source 4 is determined. For example, the analysis unit 32 deteriorates the emergency power supply 4 based on the decrease rate of the current and voltage values output from the emergency power supply 4 when the emergency lamp 1 is turned on for a predetermined period during a predetermined inspection. The state may be judged. Further, for example, the analysis unit 32 may determine the deterioration state of the emergency power supply 4 based on the decrease rate of the current and voltage values output from the emergency power supply 4 during the short-time inspection. Further, for example, the analysis unit 32 may determine the deterioration state of the emergency power supply 4 based on the transition of the current and voltage values output from the emergency power supply 4 during the short-time inspection.

  Further, for example, the analysis unit 32 further replaces the emergency power supply 4 for each of the emergency lighting devices 10A, 10B, 10C, 10D, and 10E based on the deterioration state of the emergency power supply 4 thus determined. It may be determined whether it is necessary or a future time when the emergency power supply 4 needs to be replaced. For example, the analysis unit 32 determines whether each of the emergency lighting devices 10A to 10E can turn on the emergency lamp 1 for a specified time based on the deterioration state of the emergency power supply 4. If it is determined that it cannot be lit, a warning may be notified to the inspector. Further, for example, the analysis unit 32 may determine whether or not the emergency lamp 1 can be turned on for a predetermined time in consideration of a predetermined margin. Further, for example, the analysis unit 32 determines whether or not the emergency lamp 1 can be lit at a predetermined brightness based on the current and voltage values output from the emergency power supply 4, and whether the emergency lamp 1 is predetermined. It may be determined whether or not illumination can be performed with the illuminance. The analysis of the inspection result by the analysis unit 32 may be performed in response to an analysis request to the server 30 or may be performed at a preset constant cycle.

  In addition, the control part 3, the inspection part 5, and the analysis part 32 are implement | achieved by processors and various sensors, such as CPU, DSP, FPGA, for example. The storage units 6 and 33 are realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory) and a flash memory, or a storage device such as a hard disk and an optical disk.

<Switching from slave to master>
As described above, the inspection results of all the emergency lighting devices 10A to 10E are collected in the master emergency lighting device 10A. Therefore, when the emergency lighting device 10A breaks down, the inspection result is displayed on the terminal 20. It becomes difficult to notify Thus, as described below, when the emergency lighting device 10A as a master fails, any of the emergency lighting devices 10B to 10E as slaves becomes a new master.

  FIG. 4 is a diagram illustrating an example of a processing sequence of the lighting system according to the embodiment. 5 and 6 are diagrams illustrating an example of a status list according to the embodiment. The status lists shown in FIGS. 5 and 6 are stored in the storage unit 6 of the emergency lighting device 10. In this status list, the lighting device ID is associated with the status of each emergency lighting device 10, and the status of each emergency lighting device 10 is updated by the inspection unit 5. In the following, the lighting device ID of the emergency lighting device 10A is “001”, the lighting device ID of the emergency lighting device 10B is “002”, the lighting device ID of the emergency lighting device 10C is “003”, and the emergency lighting device 10D. The lighting device ID is “004”, and the lighting device ID of the emergency lighting device 10E is “005”.

  4, in step S11, the inspection unit 5 of the emergency lighting devices 10B to 10E transmits a response request signal to the emergency lighting device 10A via the wireless communication module 2. Since the status list is in the state shown in FIG. 5 at the time of step S11, the emergency lighting devices 10B to 10E that are slaves respond to the emergency lighting device 10A that is the master according to the status list shown in FIG. Send a signal.

  In step S <b> 13, in the emergency lighting device 10 </ b> A that has received the response request signal from the emergency lighting devices 10 </ b> B to 10 </ b> E, the inspection unit 5 sends the response signal to the emergency lighting via the wireless communication module 2 in response to the response request signal. Transmit to the devices 10B to 10E.

  In step S15, in the emergency lighting devices 10B to 10E that have received the response signal from the emergency lighting device 10A, the inspection unit 5 transmits the inspection result to the emergency lighting device 10A via the wireless communication module 2.

  Here, it is assumed that a failure has occurred in the emergency lighting device 10A in step S17. Therefore, it becomes difficult to transmit a response signal from the emergency lighting device 10A.

  Therefore, in step S19, the inspection unit 5 of the emergency lighting devices 10B to 10E that are slaves receives no response signal from the emergency lighting device 10A that is the master within a predetermined time from the transmission of the latest response request signal. The status list is updated from the state shown in FIG. 5 to the state shown in FIG. That is, the inspection unit 5 of the emergency lighting devices 10B to 10E updates the status of the emergency lighting device 10A from “master” to “failure”, and among the emergency lighting devices 10B to 10E that are operating normally. Update the status of the emergency lighting device with the smallest lighting device ID from 'slave' to 'master'. With this update, in the emergency lighting devices 10B to 10E, the emergency lighting device 10B is recognized as a new master instead of the emergency lighting device 10A. That is, in the lighting system 100, when the failure of the emergency lighting device 10A that is the master occurs, the emergency lighting device 10B that is the slave switches to the master.

  Therefore, in step S21, the inspection unit 5 of the emergency lighting devices 10C to 10E transmits a response request signal to the emergency lighting device 10B via the wireless communication module 2. Since the status list is in the state shown in FIG. 6 at the time of step S21, the emergency lighting devices 10C to 10E that are slaves respond to the emergency lighting device 10B that is the master according to the status list shown in FIG. Send a signal.

  In step S23, in the emergency lighting device 10B that has received the response request signal from the emergency lighting devices 10C to 10E, the inspection unit 5 sends the response signal to the emergency lighting via the wireless communication module 2 in response to the response request signal. Transmit to devices 10C-10E.

  In step S25, in the emergency lighting devices 10C to 10E that have received the response signal from the emergency lighting device 10B, the inspection unit 5 transmits the inspection result to the emergency lighting device 10B via the wireless communication module 2.

<Structure of emergency lighting device>
FIG. 7 is a diagram illustrating a structure example of the emergency lighting device according to the embodiment. FIG. 7A is a side cross-sectional view, and FIG. 7B is a bottom view.

  In FIG. 7, the emergency lighting device 10 includes a cover 41 and a lid 42, and the housing of the emergency lighting device 10 is formed by the cover 41 and the lid 42. The emergency lamp 1 is disposed near the center of the circular lid 42 so as to penetrate the lid 42. An emergency power supply 4 and a circuit board 43 are disposed in the internal space of the casing formed by the cover 41 and the lid 42. The circuit board 43 is connected to the commercial power supply 40 and the emergency power supply 4, and the control unit 3, the inspection unit 5, and the storage unit 6 are disposed on the circuit board 43. In addition, an installation space 44 for the wireless communication module 2 is provided in an internal space formed by the cover 41 and the lid 42, and the wireless communication module 2 can be retrofitted to the emergency lighting device 10. ing. For this reason, the circuit board 43 has a connector 46 for connecting the wireless communication module 2. When the wireless communication module 2 is connected to the circuit board 43 via the connector 46, the wireless communication module 2 is supplied with power from the commercial power supply 40 or the emergency power supply 4 via the circuit board 43. Therefore, even if the emergency lighting device 10 does not have the wireless communication module 2 at the beginning, the inspection result can be wirelessly communicated by retrofitting the wireless communication module 2 via the connector 46. Further, the cover 41 and the lid 42 are usually formed of a metal that is difficult for radio waves to pass through. In view of the fact that the wireless communication module 2 is retrofitted, a through hole 45 for transmitting and receiving radio waves may be provided in the lid 42 in order to increase the sensitivity of radio transmission and reception in the wireless communication module 2. The position of the through hole 45 in the lid 42 is preferably directly below the installation space 44.

  The wireless communication module 2 retrofitted to the installation space 44 may have the pseudo load described above. When the wireless communication module 2 is installed in the installation space 44, an electric current can flow into the pseudo load.

  Note that various types of monitors such as an inspection monitor, a charge monitor, and a lamp monitor may be added to the wireless communication module 2 attached later.

  Further, the radio communication module 2 may have a string-like antenna, and the tip of the string-like antenna may protrude from the through hole 45 to further increase the radio wave transmission / reception sensitivity of the radio communication module 2. The string-like antenna may also serve as a start switch for the inspection operation of the emergency lighting device 10, and the emergency lighting device 10 may start the inspection operation by pulling the string-shaped antenna. Note that the shape of the antenna of the wireless communication module 2 is not limited to a string shape. That is, when the antenna of the wireless communication module 2 is pulled, the inspection operation of the emergency lighting device 10 is started, and the tip of the antenna or a predetermined range of the antenna is moved from the through hole 45 to the housing of the emergency lighting device 10. As long as the propagation intensity of the radio wave used for wireless communication can be improved by exposing to the outside, any shape can be adopted as the shape of the antenna.

<Inspection schedule>
In the above description, the case where the inspection unit 5 of each emergency lighting device 10 automatically inspects the emergency power supply 4 at the same timing in a fixed cycle has been described. On the other hand, the inspection unit 5 does not automatically check the emergency power supply 4, but, for example, in response to an instruction from the terminal 20, the emergency lighting device 10 </ b> A that is a master is an emergency lighting device that is a slave. An inspection start signal is transmitted to 10B to 10E, and in response to an instruction from the terminal 20 and the inspection start signal, the inspection unit 5 of each emergency lighting device 10 inspects the emergency power supply 4 at the same time. Also good. Thus, whether the inspection unit 5 automatically inspects the emergency power source 4 or according to an instruction from the terminal 20 or an inspection start signal, the inspection unit 5 of each emergency lighting device 10 has an emergency power source. 4 inspections are performed at the same timing.

  On the other hand, hereinafter, a case will be described in which the emergency lighting devices 10A to 10E are grouped into a plurality of groups and the emergency power supply 4 is inspected at different timings between different groups. In the following, the lighting device ID of the emergency lighting device 10A is “001”, the lighting device ID of the emergency lighting device 10B is “002”, the lighting device ID of the emergency lighting device 10C is “003”, and the emergency lighting device 10D. The lighting device ID is “004”, and the lighting device ID of the emergency lighting device 10E is “005”.

  FIG. 8 is a diagram illustrating an example of an inspection schedule according to the embodiment. As shown in FIG. 8, for example, the emergency lighting devices 10A, 10C, and 10E whose lighting device IDs are '001', '003', and '005' are in the first group, and the lighting device IDs are '002' and '004. 'Emergency lighting devices 10B and 10D are grouped into a second group. At this time, the emergency lighting devices 10 adjacent to each other may be grouped into different groups. Then, “odd day” is set as the inspection schedule for the emergency lighting devices 10A, 10C, and 10E belonging to the first group, and “even day” is set as the inspection schedule for the emergency lighting devices 10B and 10D. This inspection schedule is stored in the storage unit 6. Therefore, the inspection unit 5 of the emergency lighting devices 10A, 10C, 10E inspects the emergency power supply 4 on odd days according to the inspection schedule. On the other hand, the inspection unit 5 of the emergency lighting devices 10B and 10D inspects the emergency power supply 4 on even days according to the inspection schedule.
