Description

  The present invention relates to an emergency lighting system that lights a lamp with an emergency power source such as a secondary battery when a common power source such as a guide light or an emergency light fails.

  Conventionally, an emergency lighting device has been provided with a switch for forcibly stopping the power supply from the utility power supply (commercial power supply) to the lamp to make a pseudo power outage. The secondary battery is inspected by operating the hanging strap and turning on the switch to supply electric power from the secondary battery and to turn on the lamp. Emergency lighting devices such as guide lights and emergency lights are used to turn on (emergency lighting) the lamp with an emergency power source consisting of a secondary battery in the event of a power failure due to a fire or an earthquake. It is required by the Fire and Disaster Management Agency Notification and the Building Standards Law to regularly check whether it is normally performed. According to the provisions of the Fire and Disaster Management Agency and the Building Standard Law, the lamps are effectively turned on for 20 minutes or 60 minutes in the case of guide lights with power supplied from secondary batteries, and 30 minutes in the case of emergency lights. It is supposed to be allowed. The inspector needs to monitor whether or not the lamp can be effectively lit during the specified period by suspending a weight on the drawstring and turning on the switch during the specified period. Moreover, in general, guide lights and emergency lights are installed at multiple locations in the building, so it is necessary to look around each of the lighting devices one by one, which is very time-consuming for the inspector. Work. Accordingly, various lighting devices have been proposed that are intended to automate and save labor for inspection of the secondary battery as described above.

2. Description of the Related Art Conventionally, a guide lamp device having timer means for outputting an inspection start signal at regular intervals, power supply switching means, and inspection means for measuring charging current and induction lamp current is known. The inspection is automatically performed (see, for example, Patent Document 1). In addition, the central monitoring control unit and multiple individual emergency lighting units are wired in a loop, and the control unit of each individual emergency lighting unit has a diagnostic circuit including voltage and current detection means to control past diagnostic results for each control. There is known a system in which a unit stores a past diagnosis result in response to a request from a central monitoring control unit (for example, see Patent Document 2).
Japanese Patent No. 2744185 JP-A-3-228497

  However, although the guide lamp apparatus as shown in Patent Document 1 described above can be inspected by itself, an inspector who confirms the inspection result usually makes a round once every several months. If an abnormality has occurred during that time, it is impossible to confirm when the abnormality has occurred and whether the inspection act itself has been performed normally. It has become.

  Moreover, the diagnostic communication system of the emergency lighting unit as shown in Patent Document 2 is to wire-connect a plurality of individual emergency lighting units in a loop shape, which requires a great deal of trouble during wiring construction. In order to confirm the position of the individual emergency lighting unit with the central control and monitoring unit, a correspondence table between the layout map and the address is required.

  SUMMARY OF THE INVENTION An object of the present invention is to solve the above-described problems, and to provide an emergency lighting system that can realize automation and labor saving of inspection work of a secondary battery and that can be easily installed.

In order to achieve the above object, the invention of claim 1 is directed to a lamp that serves as a light source, a secondary battery that supplies power to the lamp, and a charge that charges the secondary battery by receiving power from an external utility power source.

In infrared The medium communicates with each other via the communication unit, and is usually installed at one corner of the floor, and has a display unit for displaying the address table of the lighting device, and the communication unit of the remote controller And the communication unit of the lighting device with high priority given according to the arrangement place has a low power wireless transmission / reception unit using radio waves, and when an abnormality occurs in the lighting device with high priority, the lighting device The transmitter itself transmits an abnormality to the remote controller using the radio transmission / reception unit, the remote controller displays the address of the illumination device that has transmitted the abnormality signal on the display unit, and the illumination device with a lower priority is transmitted from the remote controller. When the inspection result request signal is received, the emergency lighting system transmits the inspection result by the inspection unit to the remote controller via the communication unit .

  According to the invention of claim 1, when an abnormality occurs in the lighting device, the abnormality is transmitted to the remote controller, so that the inspector can detect the abnormality of the guide light via the remote control without connecting the guide light with the communication line. It becomes possible to detect quickly. Further, the inspector can easily perform maintenance by confirming the inspection result by the inspection means via the remote controller. In addition, it is possible to confirm whether the inspection is performed reliably, and the reliability of the system can be obtained. Furthermore, since the inspection result can be confirmed in front of the lighting device, it is not necessary to confirm the position with reference to the building layout. In addition, since the lighting device is not connected by a signal line, the construction of the signal line is not required, it can be easily replaced with an existing building, and the workability is good. In addition, even if there is no transmission of an abnormality from the lighting device, the inspector can go around once every few months and grasp the status of each lighting device by using the remote control, saving labor for inspection. it can.

In addition, it is possible to preferentially detect an abnormality in a lighting device having a high priority order and respond quickly.

  Hereinafter, an embodiment of an emergency lighting system embodying the present invention will be described with reference to the drawings. FIG. 1 shows the configuration of an emergency lighting system. The illumination system in the present embodiment includes a plurality of guide lights (illumination devices) 1 including a communication unit 11 capable of bidirectional communication, and a communication unit 24 and a display unit 23 capable of bidirectional communication with each guide light. It comprises a remote controller 2 provided. Each guide light 1 is connected only to a power line (ordinary power source, commercial power source) 3.

  FIG. 2 shows the configuration of the guide light 1. The guide lamp 1 includes a lamp 12 that performs guidance display, a lighting circuit unit 13 that lights the lamp 12, a secondary battery 14 that serves as a power source in the event of a power failure, and a charging circuit that charges the secondary battery 14 with power from the power line 3 (charging) Means) 14a, an inspection circuit unit (inspection) for determining whether the current and voltage of the lamp 12 and the secondary battery 14 are equal to or higher than a reference value after the lighting operation by the secondary battery 14 is performed during a certain inspection time. Means) 15, a timer circuit unit (internal timer) 16 for measuring the inspection time, a storage unit 17 for storing the self-address of the guide light 1 and the inspection result, and a communication unit 11 for transmitting and receiving with the remote controller.

  FIG. 3 shows the configuration of the remote controller 2. The remote controller 2 displays an operation unit 21 that performs an operation for transmitting an inspection command or the like to the guide light 1, and a control unit 22 that controls the operation of the transmission command or the like based on a command from the operation unit 21, for example, an inspection result. It is comprised from the communication part 24 which performs the two-way communication with the display part 23 and the guide light 1. FIG. For example, infrared light may be used as the bidirectional communication medium, and both the communication unit 11 of the guide light and the communication unit 24 of the remote controller have an infrared light emitting unit and an infrared light receiving unit.

  Address setting in the emergency lighting system performed immediately after the above-described guide light 1 is installed will be described. In this system, when the guide lights 1 are constructed, the guide lights 1 are only connected by the power line 3. For this reason, first, in order to identify each guide light 1, the address of each guide light 1 is set. The address of the guide light 1 is composed of, for example, a group name and an individual number within the group. The address is set by displaying the group name and the individual number on the display unit 23 of the remote controller 2 and setting the address in the remote controller, and then transmitting the address information to the guide lamp 1. The guide light 1 that has received the address stores the transmitted address in the storage unit 17 in the guide light, and sends back to the remote controller 2 that the setting has been completed. Such a setting operation is performed for each guide light 1, and the address of each guide light 1 is set.

  The performance check operation of the secondary battery 14 in the guide light 1 will be described. FIG. 4 shows a flowchart of the inspection operation. The inspection of each guide light 1 is started when the inspector transmits an initial inspection command to the guide light 1 using the remote controller (# 1). The guide lamp 1 that has received the inspection command checks whether or not a certain charging time (for example, 24 hours) has elapsed since the power of the guide lamp 1 was turned on (# 2). If the charging time has not elapsed (No in # 2), an inspection impossibility signal is transmitted from the guide light 1 to the remote controller 2, and the inspection flow ends (# 3). This is because the battery cannot be accurately inspected unless it is charged for a certain period of time.

  If the charging time has elapsed (Yes in # 2), the power source is switched from the power line 3 to the secondary battery drive (# 4), and the timer circuit unit 16 is used to measure the time elapsed for inspection. The inspection time timer (T1) starts measuring time (# 5). The inspection circuit unit 15 of the guide light 1 is in a standby state until the measured value T1 of the inspection time timer exceeds 20 minutes as a predetermined inspection time (No in # 6), and the inspection time timer ends after 20 minutes. Then (Yes in # 6), the voltage of the secondary battery 14 is measured (# 7), it is determined whether or not the measured voltage value is equal to or higher than the reference value, and the pass / fail is stored in the storage unit 17 (# 8). ). Next, time measurement of the inspection interval timer (T2) in the timer circuit unit 16 is started (# 9). Thereafter, when the measurement value T2 of the inspection interval timer is within 3 months, which is the inspection interval (No in # 10), the inspection circuit unit of the guide light 1 enters the inspection standby state, and when the measurement value T2 has elapsed for 3 months. (Yes in # 10), the above inspection is repeated.

  The inspector, for example, collects inspection results from each guide light 1 using the remote controller 2 once every six months. Upon receiving the inspection result request signal from the remote controller 2, the inspection circuit unit 15 of the guide lamp 1 transmits the inspection result stored in the storage unit 17 to the remote controller 2 via the communication unit 11. The inspector sees the transmitted content displayed on the display unit 23 of the remote controller 2, and as a result of the inspection performed by the inspection circuit unit 15 of the guide light 1 while not visiting the patrol, the inspection itself Can be ascertained whether or not According to such an emergency lighting system, whether or not the inspection is reliably performed can be grasped by patrol, and the reliability of the system can be ensured. Moreover, since the number of times of patrol for inspection can be reduced, there is an effect that inspection costs can be reduced.

  Next, another embodiment of the emergency lighting system according to the present invention will be described. The system configuration of this embodiment is the same as that shown in FIG. The difference from the above-mentioned system is that the contents of inspection are not one type but a plurality of inspections are performed, and the software of the inspection circuit unit 15 of the guide light 1 is different. FIG. 5 shows a flowchart of the inspection. When an inspection command is transmitted to the guide light 1 from the remote controller 2 (# 11), the inspection circuit unit 15 checks whether 24 hours have elapsed since the power of the guide light 1 is turned on. If there is not, it will be in a standby state (No in # 12), and if it has passed (Yes in # 12), a periodic inspection is started (# 13). Here, the periodic inspection is, for example, inspection accompanied by discharge from the battery for 20 minutes.

  When the periodic inspection is started, the power source of the guide lamp 1 is switched from the power line 3 to the secondary battery 14, and the periodic discharge timer (TH) of the timer circuit unit 16 starts measuring time (# 14). The inspection circuit unit 15 waits until the measured value TH has passed 20 minutes (No in # 15), and when 20 minutes have passed (Yes in # 15), measures the voltage of the secondary battery 14, and the voltage value is the reference value. It is determined whether or not it is above, and the power source is switched from the secondary battery 14 to the power line 3, and then the determination result is stored in the storage unit 17 as a periodic inspection result (# 16).

  Subsequently, the periodic interval timer (TK) of the timer circuit unit 16 starts measuring time (# 17). If the measured value TK is within 3 months, which is the inspection interval (No in # 18), daily inspection is started (# 19). Here, the daily inspection is an inspection for detecting the end of the battery life, for example, by performing a short discharge for one minute at a frequency of once a week, for example. When this daily inspection is started, the power source is switched from the power supply line 3 to the secondary battery 14, and the daily discharge timer (NH) of the timer circuit unit 16 starts measuring time (# 20). The inspection circuit unit 15 waits until the measured value NH has elapsed for 1 minute (No in # 21), and after 1 minute has elapsed (Yes in # 21), measures the voltage of the secondary battery 14, and the voltage value is the reference value. It is determined whether or not it is above, and the power source is switched from the secondary battery 14 to the power line 3, and then the determination result is stored in the storage unit 17 as a periodic inspection result (# 22).

  Subsequently, the daily interval timer (NK) of the timer circuit unit 16 starts measuring time (# 23). When the measurement value NK is an inspection interval, for example, within one week (No in # 24), continuous monitoring is performed (# 25). Here, the constant monitoring is monitoring that is always performed while the guide lamp is energized, and the lamp current and the charging current and charging voltage of the secondary battery 14 are measured. Is stored in the storage unit 17. At the same time, the above-mentioned regular interval timer (TK) is checked (# 26). If the measured value TK is within 3 months, which is the inspection interval (No in # 26), the daily interval timer (NK) is set. The check is continued (# 24). If the measured value TK has passed three months (Yes in # 26), a periodic inspection is performed (# 13). If one week has passed while checking the daily interval timer (NK) (Yes in # 24), daily inspection is started (# 19).

  When the guide light 1 performs the above-described inspection operation, a plurality of inspections with different inspection time intervals and inspection contents can be performed. The inspector, for example, collects inspection results using the remote controller 2 once every six months. Upon receiving the inspection result request signal from the remote controller 2, the inspection circuit unit 15 of the guide lamp 1 transmits the inspection result stored in the storage unit 17 to the remote controller 2 via the communication unit 11. The inspector sees the transmitted multiple types of inspection contents on the display unit 23 of the remote controller 2 and sees the multiple types of inspections performed by the guide light inspection circuit unit 15 while not visiting the patrol. As a result, it is possible to grasp whether the inspection itself has been performed reliably. According to such an emergency lighting system, since inspections are performed at short time intervals, it is more reliable to determine when an abnormality has occurred with higher time accuracy than with the emergency lighting system according to the above-described embodiment. Can grasp.

  Next, still another embodiment of the emergency lighting system according to the present invention will be described. The system configuration of this embodiment is the same as that shown in FIG. The remote controller in this embodiment will be described. FIG. 6 shows the configuration of the remote controller 2. The remote controller 2 has a configuration in which a storage unit 25 for data storage is added to the remote controller shown in FIG. The remote controller 2 can store the past history of each guide light 1 in the storage unit 25 based on the address information of each guide light 1. The guide light 1 in this embodiment starts the inspection similar to the above-described inspection contents from the time when the inspection command is transmitted from the remote controller 2.

  7 and 8 show a screen and an operation unit displayed on the display unit 23 of the remote controller 2 by a touch panel method. When the remote controller 2 is energized, a table 31 and various buttons for operation are displayed on the display unit 23 as shown in FIG. The operation buttons are, for example, an address setting button 32, an inspection result confirmation button 33, a history confirmation button 34, an arrow button 35, and an enter button 36, and the operation is performed by touching the displayed buttons. The address setting button 32 is a button used for setting an address at the time of construction of the guide light. The inspection result confirmation button 33 is a button for receiving the inspection result stored in the guide light by operating near the guide light and displaying it on the remote controller for confirmation. The history confirmation button 34 is a button for displaying and confirming the examination history stored in the storage unit 25 of the remote controller 2. The arrow button 35 and the determination button 36 are buttons for moving and selecting the cursor 35c on the display unit.

  The table 31 shows the address of each guide light, and only the address of the guide light 1 for which an address has already been set is indicated by the group name and the individual number in the group. When the inspector makes a patrol, he goes to the vicinity of the guide light 1 with such a remote controller 2 and operates the check result confirmation button 33 to receive the inspection result from the guide light 1 and store it in the storage unit 25. At that time, if the inspection details reported by the guide light 1 are abnormal contents, the individual number of the address indicating the guide light 1 blinks, and the inspector is notified of the abnormality of the guide light 1. When there is such blinking indicating an abnormality, the inspector uses the arrow button 35 of the operation unit to move the cursor 35c to the individual number of the blinking address, selects the address using the enter button 36, and further When the history confirmation button 34 is pressed, a history display screen 37 shown in FIG. 8 is displayed.

  The history display screen 37 displays the address of the designated guide light and the inspection history. The result display screen button 38 is a button for scrolling the screen when the content of the inspection result is large, or displaying the history display screen from another screen described later. The history change button 39 is a button used when the inspector rewrites the history by additional entry or the like. The displayed history content is, for example, the inspection date and time, the inspection content, and the result. These histories are stored in the storage unit 25 of the remote controller 2 and are the inspection results acquired from the storage unit 17 of the guide light 1, and the past histories in the storage unit 25 of the remote controller based on the address when the inspection results are received. It was added to. Since the inspector can check not only the inspection state after the last patrol but also the history since the installation of the appliance, the inspector can understand the detailed appliance status. Based on this history, for example, the secondary battery 14 You can guess the next replacement time. In this way, the inspector can not only save the labor of the inspection but also can grasp a more detailed inspection situation, so the replacement time of the parts can be predicted, and a quick response in the maintenance of the guide light 1 becomes possible.

  Next, still another embodiment of the emergency lighting system according to the present invention will be described. The system configuration of this embodiment is the same as that shown in FIG. In this system, not only the electrical characteristics of the guide lamp 1 but also the inspection items on the appearance are stored in the inspection history as inspection results. The remote controller is the same as that shown in FIG. 6, and has a storage unit 25 for data storage. The guide light 1 starts the same inspection as that described above from the time when the inspection command is transmitted from the remote controller 2.

  9 to 11 show a screen and an operation unit displayed on the display unit 23 of the remote controller 2 by a touch panel method. The inspector receives an electrical inspection result (for example, a pass / fail judgment result by measuring the secondary battery voltage, a lamp current confirmation result, etc.) from each guide light during the patrol, and the history screen 37 as shown in FIG. Can grasp the state of each guide light. In addition, the control unit 22 of the remote controller has inspection processing means for manually inputting confirmation contents on the appearance of the guide light by the inspector. In order to make this inspection processing means function, the inspector presses the appearance inspection button 40, shifts to the screen shown in FIG. 10, operates the cursor 35c, and uses the contents of the appearance check performed by the right holder as a procedure. Can be stored in the history. That is, when the appearance inspection button 40 is pressed, the inspection procedure 41 shown in FIG. 10 is displayed on the display screen of the remote controller. When the inspector performs an appearance inspection, moves the cursor 35c with the arrow button 25 on the display screen, selects YES or NO, and confirms with the decision button 36 or the setting button 42, the result is automatically guided to the remote controller 2 concerned. It is added to the history of lamp 1.

  Further, when the inspection result stored in the guide light 1 is received by operating the inspection result confirmation button 33 in FIG. 7 described above, for example, the measured voltage value of the secondary battery is included in the inspection result content of the guide light 1. If there is an abnormality determination such as being below the reference value, an exchange procedure 44 shown in FIG. 11 is displayed. When the right holder performs predetermined maintenance work such as parts replacement and selects YES or NO in the same manner as described above, the result is automatically added to the history of the guide light of the remote controller. The

  According to such an emergency lighting system, not only the electrical inspection result performed by the guide light but also the appearance inspection result manually performed by the inspector can be added to the history as the history of the lighting device stored in the remote control. , More detailed instrument information is grasped. Further, since the inspector only needs to perform the inspection in accordance with the procedure displayed on the screen, there is no inspection omission and a more reliable inspection can be performed.

  Next, still another embodiment of the emergency lighting system according to the present invention will be described. FIG. 12 shows an example of guide light arrangement construction of this system. The remote controller in the present embodiment has the same basic configuration as that shown in FIG. 6, but is usually installed at one corner of the floor (remote controller 60), and has a communication unit using radio waves as described later. Is different. The black circles ● shown in FIG. 12 indicate each of the constructed guide lights. Each guide light is identified and displayed by an address composed of a group name and an individual number, for example, as the guide light 1 at address 7-1. The guide lights 1 are provided with a priority order according to the arrangement location. For example, since the guide lights at addresses 2-6, 5-3, 7-1, and 1-1 are provided at the entrance / exit E, people are concentrated in an emergency, and are more important than other guide lights. It is necessary to inspect and perform maintenance.

  In this system, the guide light 1 having a high priority has a function of notifying the remote controller 60 of an abnormality by itself when an abnormality occurs in the guide light 1. Therefore, the high-priority guide light 1 includes a low-power wireless transmission / reception unit using radio waves in the communication unit 11, and the remote controller 60 includes a low-power wireless transmission / reception unit using radio waves in the communication unit 24. These guide lights 1 are inspected in the same manner as described above from the time when the inspection command is transmitted from the remote controller 60. And, for example, the guide lights 1 of the addresses 2-6, 5-3, 7-1, 1-1 having a high priority spontaneously transmit a signal radio wave indicating abnormality when the inspection result is abnormal. 12 is transmitted to the remote controller 60 which is disposed at the end of the floor shown in FIG. As shown in FIG. 13, the display unit 23 of the remote control 60 that has received the abnormal signal displays, for example, a blinking display ● in the address portion of the guide light that has transmitted the abnormal signal in the address table 31 of the guide light, and there is an abnormality. The inspector is notified by voice. According to the emergency lighting system, it is possible to quickly detect an abnormality of the guide lamp 1 without coupling the guide lamp 1 with a communication line.

  The present invention is not limited to the above-described configuration, and various modifications can be made. For example, in each of the above embodiments, bidirectional communication is performed between the remote control and each guide light, and the address information and inspection result information of each guide light is shown. When it is brought and communicated, at least the inspection result may be communicated.
