May communicate with the wireless communication module 2A.

<Configuration and operation of emergency lighting equipment>
FIG. 2 is a diagram showing 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 the commercial power supply 40. Hereinafter, operations common to both the master emergency lighting device and the slave emergency lighting device will be described.

The emergency lamp 1 lights up at least when the power supply from the commercial power source 40 is stopped.

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

The control unit 3 charges the emergency power supply 4 with the commercial power supply 40 at all times except in an emergency, and lights the emergency lamp 1 with the emergency power supply 4 in an emergency. Further, the control unit 3 constantly operates the wireless communication module 2, the inspection unit 5, and the storage unit 6 by the commercial power supply 40. The control unit 3 may operate the wireless communication module 2 by the commercial power supply 40 at all times and by 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 shall refer to the inspection for determining the abnormality of the emergency power supply 4 (hereinafter sometimes referred to as "abnormality inspection") for the predetermined time specified by law (hereinafter referred to as "regular time specified by law"). There is) only do. In addition, the inspection unit 5 sets the predetermined period specified by law (hereinafter sometimes referred to as the "specified period of law") as the first inspection cycle, and this time when the specified period of law has passed since the previous abnormality inspection. Check for abnormalities. That is, the inspection unit 5 periodically inspects the abnormality for the time specified by the law according to the period specified by the law. In the following, anomalous inspections that are regularly performed only for the prescribed time of the law according to the prescribed period of the law may be referred to as "regular inspection of the law".

Further, the inspection unit 5 performs an inspection for diagnosing the state of the emergency power supply 4 (hereinafter, may be referred to as "state diagnosis inspection") for a predetermined time shorter than the statutory predetermined time (hereinafter, "predetermined short time"). (Sometimes called). In addition, the inspection unit 5 sets a predetermined period shorter than the legally specified period (hereinafter sometimes referred to as "predetermined short period") as the second inspection cycle, and when the predetermined short period has elapsed from the previous state diagnosis inspection. We will carry out this condition diagnosis and inspection. That is, the inspection unit 5 periodically performs a state diagnosis inspection for a predetermined short period of time according to a predetermined short period of time. In the following, a state diagnosis inspection that is regularly performed for a predetermined short period of time according to a predetermined short period may be referred to as a "short-time inspection".

In this way, the inspection unit 5 performs regular legal inspections in the first inspection cycle and short-time inspections in the second inspection cycle shorter than the first inspection cycle. In the following, when the regular legal inspection and the short-time inspection are explained without distinction, they are simply described 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 inspects the emergency lighting device 10, 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 an inspection result. Further, for example, in the short-time inspection, the inspection unit 5 lights the emergency lamp 1 using the electric power supplied from the emergency power supply 4 for a predetermined short time (for example, about 15 seconds), and before and after the lighting, the emergency lamp 1 is lit. The values of the voltage and current supplied by the power supply 4 may be stored in the storage unit 6 as an inspection result. For example, even if the lighting is performed for a short period of about 15 seconds, changes in the values of the supply voltage and supply current from the emergency power supply 4 before and after lighting can cause deterioration of the emergency power supply 4, detection of defective products, and replacement time. It can be used for state diagnosis and inspection such as prediction of. The time per inspection of the emergency power supply 4 by the inspection unit 5 is preferably 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 chronological order. Since the capacity of the storage unit 6 is limited, the storage unit 6 may store only the inspection results for three years from the current date and time, for example.

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 turning 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. It may have a pseudo load through which only current flows. Since the emergency lighting device 10 has a pseudo load, when the inspection unit 5 or the wireless communication module 2 operates in the short-time inspection, a current flows to the pseudo load instead of the emergency lamp 1. When the inspection is performed for a short time, the emergency lamp 1 does not light because the current flows to the pseudo load instead of the emergency lamp 1. The pseudo load is arranged in, for example, the wireless communication module 2.

<Slave operation>
Next, the operation peculiar to the emergency lighting device which is 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 result stored in the storage unit 6 at a fixed reporting cycle and outputs the inspection result to the wireless communication module 2. For example, when the inspection cycle is "1 day", "1 month" is set as a reporting cycle longer than the inspection cycle in the inspection unit 5, and the inspection unit 5 sets a predetermined date and time of each month as the reporting date and time. The inspection result for one month (for example, when the report date and time is 10:00 am on the first day of every month, the inspection result for one month last 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 to the emergency lighting device 10A which is the master. That is, each of the wireless communication modules 2B to 2E transmits the one-month inspection result of each of the emergency lighting devices 10B to 10E to the wireless communication module 2A at a predetermined date and time of each month.

<Master operation>
Next, the operation peculiar to the emergency lighting device which is the master will be described. The wireless communication module 2A of the emergency lighting device 10A, which is the master, receives the one-month inspection results transmitted from the wireless communication modules 2B, 2C, 2D, 2E of the emergency lighting devices 10B, 10C, 10D, and 10E, respectively. , The received inspection result for one month is output to the inspection unit 5. The inspection unit 5 stores the inspection results of the emergency lighting devices 10B, 10C, 10D, and 10E in the storage unit 6 together with the inspection results of the emergency lighting device 10A (that is, its own device). That is, the inspection unit 5 collects the inspection results of all the emergency lighting devices 10A to 10E and stores them in the storage unit 6. Then, when the inspection unit 5 receives the inspection result acquisition request from the terminal 20 via the wireless communication module 2A, the inspection unit 5 receives the inspection results stored in the storage unit 6, that is, all of the emergency lighting devices 10A to 10E. The inspection result of 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 according 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. Further, at this time, the inspection unit 5 sets the transmission destination of the inspection result to 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 in response to the inspection result acquisition request. The inspection result (that is, the inspection result in all the emergency lighting devices 10A to 10E) is received. Then, the terminal 20 transmits the inspection result received from the emergency lighting device 10A to the server 30.

The terminal 20 may automatically transmit an inspection result acquisition request when the terminal 20 is within a predetermined distance from the master emergency lighting device 10A. 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 showing a configuration example of the server according to the embodiment. In FIG. 3, the server 30 has 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 the emergency lighting devices 10A to 10E) and outputs the inspection result 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 of the emergency power supplies 4 of the emergency lighting devices 10A, 10B, 10C, 10D, and 10E. Then, the determination result is output to the wireless communication module 31 and stored in the storage unit 33. 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 touch panel of the terminal 20 displays the determination result by the analysis unit 32 for each lighting device ID.

For example, the analysis unit 32 determines each of the emergency lighting devices 10A, 10B, 10C, 10D, and 10E based on at least one of the voltage, current, temperature, discharge time, and number of discharges included in the inspection result. Determine the deterioration state of the power supply 4. For example, when the analysis unit 32 lights the emergency lamp 1 for a predetermined period during a predetermined inspection, the emergency power supply 4 deteriorates based on the reduction rate of the current and voltage values output by the emergency power supply 4. You may judge the state. Further, for example, the analysis unit 32 may determine the deterioration state of the emergency power supply 4 based on the reduction rate of the current and voltage values output by 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 by the emergency power supply 4 during the short-time inspection. Further, for example, the analysis unit 32 is based on the behavior change caused by switching from the charging current to the discharge current due to the discharge in a short time during the short-time inspection and the behavior change of the discharge rate in a short time at the start of discharge. The deteriorated state of the emergency power supply 4 may be determined.

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

The analysis unit 32 may not analyze the inspection result at the time of the periodic inspection of laws and regulations, but may analyze the inspection result only at the time of the short-time inspection.

The control unit 3, the inspection unit 5, and the analysis unit 32 are realized by, for example, a processor such as a CPU, DSP, FPGA, or various sensors. Further, the storage units 6 and 33 are realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory, or a storage device such as a hard disk or 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 emergency lighting device 10A which is the master. Therefore, when the emergency lighting device 10A fails, the inspection results are displayed on the terminal 20. It becomes difficult to notify to. Therefore, in the event of failure of the master emergency lighting device 10A, any of the slave emergency lighting devices 10B to 10E becomes a new master as follows.

FIG. 4 is a diagram showing an example of a processing sequence of the lighting system according to the embodiment. 5 and 6 are diagrams showing an example of the status list according to the embodiment. The status list shown in FIGS. 5 and 6 is stored in the storage unit 6 of the emergency lighting device 10. In this status list, the lighting device ID and the status of each emergency lighting device 10 are associated with each other, 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 of the emergency lighting device 10E is '004', and the lighting device ID of the emergency lighting device 10E is '005'.

In FIG. 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 slave emergency lighting devices 10B to 10E request a response to the master emergency lighting device 10A according to the status list shown in FIG. Send a signal.

In step S13, in the emergency lighting device 10A that has received the response request signal from the emergency lighting devices 10B to 10E, the inspection unit 5 illuminates the response signal via the wireless communication module 2 in response to the response request signal. It transmits 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 occurs in the emergency lighting device 10A in step S17. Therefore, it becomes difficult to transmit the response signal from the emergency lighting device 10A.

Therefore, in step S19, when the inspection unit 5 of the slave emergency lighting devices 10B to 10E does not receive the response signal from the master emergency lighting device 10A 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 operating normally. Update the status of the emergency luminaire with the smallest luminaire 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 in place of the emergency lighting device 10A. That is, in the lighting system 100, when the emergency lighting device 10A, which is the master, fails, the emergency lighting device 10B, which is the slave, is switched to the master.

Therefore, in step S21, the inspection unit 5 of the emergency lighting devices 10C to 10E transmits the 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 slave emergency lighting devices 10C to 10E request a response to the master emergency lighting device 10B 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 illuminates the response signal via the wireless communication module 2 in response to the response request signal. Transmission to devices 10C to 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 showing a structural example of the emergency lighting device according to the embodiment. 7 (A) is a side sectional view, and FIG. 7 (B) is a bottom view.

In FIG. 7, the emergency lighting device 10 has a cover 41 and a lid 42, and the cover 41 and the lid 42 form a housing of the emergency lighting device 10. The emergency lamp 1 is arranged near the center of the circular lid 42 so as to penetrate the lid 42. The emergency power supply 4 and the circuit board 43 are arranged in the internal space of the housing formed by the cover 41 and the lid 42. The circuit board 43 is connected to a commercial power supply 40 and an emergency power supply 4, and a control unit 3, an inspection unit 5, and a storage unit 6 are arranged on the circuit board 43. Further, an installation space 44 for the wireless communication module 2 is provided in the 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. Therefore, 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 in the emergency lighting device 10 that does not initially have the wireless communication module 2, 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 made of a metal through which radio waves do not easily pass. Therefore, in consideration of the fact that the wireless communication module 2 is retrofitted, it is preferable to provide a through hole 45 for transmitting and receiving radio waves in the lid 42 in order to increase the sensitivity of transmitting and receiving radio waves 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 above-mentioned pseudo load. When the wireless communication module 2 is installed in the installation space 44, current can flow into the pseudo load.

In addition, various monitors such as an inspection monitor, a charging monitor, and a lamp monitor may be added to the retrofitted wireless communication module 2.

Further, the antenna of the wireless communication module 2 may be formed into a string shape, and the tip of the string-shaped antenna may be projected from the through hole 45 to further increase the sensitivity of transmitting and receiving radio waves of the wireless communication module 2. Further, the string-shaped antenna may also serve as an activation 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. The shape of the antenna of the wireless communication module 2 is not limited to the 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 activated, and the tip of the antenna or a predetermined range of the antenna is extended from the through hole 45 to the housing of the emergency lighting device 10. Any shape of the antenna can be adopted as long as the propagation strength of the radio wave used for wireless communication can be improved by exposing the antenna to the outside.

<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 of a fixed cycle has been described. On the other hand, the inspection unit 5 does not automatically inspect the emergency power supply 4, but, for example, the emergency lighting device 10A, which is the master, is the slave in response to an instruction from the terminal 20. An inspection start signal is transmitted to the 10B to 10E, and the inspection unit 5 of each emergency lighting device 10 simultaneously inspects the emergency power supply 4 at the same timing according to the instruction from the terminal 20 and the inspection start signal. Is also good. In this way, regardless of whether the inspection unit 5 automatically inspects the emergency power supply 4 or according to the instruction from the terminal 20 or the inspection start signal, the inspection unit 5 of each emergency lighting device 10 has an emergency power supply. The inspection of 4 will be performed at the same timing.

On the other hand, the case where 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 will be described below. 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 of the emergency lighting device 10E is '004', and the lighting device ID of the emergency lighting device 10E is '005'.

FIG. 8 is a diagram showing 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 having the lighting device IDs of '001', '003', and '005' are in the first group, and the lighting device IDs are' 002', '004. 'Emergency lighting devices 10B and 10D are grouped into the second group. At this time, the emergency lighting devices 10 adjacent to each other may be grouped into different groups. Then, "odd days" are set as the inspection schedule of the emergency lighting devices 10A, 10C, 10E belonging to the first group, and "even days" are set as the inspection schedule of the emergency lighting devices 10B, 10D. This inspection schedule is stored in the storage unit 6. Therefore, the inspection unit 5 of the emergency lighting devices 10A, 10C, and 10E inspects the emergency power supply 4 on odd-numbered 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-numbered days according to the inspection schedule. That is, the emergency lighting devices 10A, 10C, 10E belonging to the first group and the emergency lighting devices 10B, 10D belonging to the second group check the emergency power supply 4 at different timings. The number of groups to be grouped is not limited to two, and may be three or more.
