Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a car illumination inspection system for inspecting the operating state of a fluorescent lamp that illuminates the inside of an elevator car.

[0002]

2. Description of the Related Art As a starter for a fluorescent lamp, a glow starter using a glow bulb and an electronic starter using a power element whose firing angle can be controlled are well known. When a glow starter is used, the fluorescent lamp repeatedly turns on and off at the end of its life, which gives an occupant of the elevator an unpleasant feeling. Therefore, JP-A-7-215636 and JP-A-9-106893 are used. As described in the official gazette, it is desirable to provide a system that detects the sign of the end of life based on, for example, the current waveform and promotes early replacement. In contrast,
If an electronic starter is used, the amount of light of the fluorescent lamp that has reached the end of its life will only decrease, and in the first place, it will not repeatedly turn on and off. For this reason, there are many examples of adopting an electronic starter, which is reluctant to repeatedly turn on and off. In particular, for fluorescent lights used as elevator car lighting, it is necessary to devise ways to reduce the anxiety and discomfort given to elevator users as much as possible because the closed space inside the car is illuminated. In connection with the fact that there are many cases where the number of elevator users is unspecified, there is a tendency for electronic starters to be used frequently.

Control of the elevator car lighting is generally performed according to a control procedure as shown in FIG. In the procedure of this figure, the elevator car lighting is used when there is a call from the hall (S101) or when there is a call from inside the car (S).
102) (S103), and a predetermined time (usually about 3 to 5 minutes) has passed since it was turned on, which is considered to be the end or suspension of operation (S104) and turned off (S104).
105). Then, the control operation returns to step S101. That is, the light is turned on before the passenger gets into the car, the illumination is continued at least during the period when the passenger is (maybe), and then automatically turned off to suppress the power consumption.

[0004]

However, when the power supply voltage is lowered due to a lightning strike on the power transmission line or other accidents or the ambient temperature is low, the electronic starter may fail to turn on the fluorescent lamp. Further, if the power supply voltage drops due to a lightning strike on the power transmission line or other accident while the car is illuminated, some or all of the fluorescent lights that illuminate the interior of the car may be turned off. In these situations, there is a possibility that the fluorescent lamp that has failed to be turned on or has been turned off may be successfully turned on by executing the control or operation for turning off and turning on the fluorescent lamp once. However, in the procedure shown in FIG. 5, the lighting control is not performed until the predetermined time has elapsed after the lighting was commanded and the lights were automatically turned off.
Therefore, if some or all of the fluorescent lamps are not normally lit and the illuminance of the car lighting is low for a relatively long time, and if there is an occupant in the car, that occupant may feel uncomfortable. Becomes

The problem is that when the number of fluorescent lamps that have failed to light up or are turned off accounts for a large proportion of the total number of fluorescent lamps associated with the car, this is especially true for all fluorescent lamps associated with that car. When it corresponds to, it becomes remarkable. In addition, when a fluorescent lamp that cannot be turned on is detected and the result is automatically notified to the abnormality monitoring center and a worker or technician is dispatched for replacement or investigation, the operation or control of turning off and relighting is executed. If it is done, it will be dispatched even in a situation where it can be turned on.

The present invention has been made to solve the above problems, and when the lighting of the fluorescent lamp fails or when the fluorescent lamp is turned off due to an accident or the like, the car lighting has a low illuminance. The purpose is to reduce the time required to become a worker and prevent unnecessary use of workers and engineers.

[0007]

In order to achieve such an object, in a car lighting inspection system according to the present invention, a fluorescent lamp (in the case of an electronic starter, the light quantity is Detects a car requiring inspection that has a deteriorated fluorescent lamp or a glow starter that repeatedly turns on and off, and when it can be considered that there is no occupant, turn off the fluorescent lamp for the car requiring inspection by the extinguishing means and then turn it off When the predetermined time has elapsed, the relighting trial means tries to light the fluorescent lamps related to the car requiring inspection.

More preferably, all the lights requiring inspection are detected in which all the fluorescent lights are not normally turned on even though the lights are instructed, and all the lights are turned off by the processing means to stop the cars at the nearest floor. Then, the door is opened, and then the extinguishing means and the relighting trial means are operated.

More preferably, since it corresponds to all the cars requiring inspection, the extinguishing means and the relighting trial means are operated to try to turn on the fluorescent lamps, but at least a part of the fluorescent lamps fails to be turned on, and the car still needs to be checked. For cars that are in the state that all cars require inspection, at least one of the processes for all non-lighting processing means to turn on the emergency lights of the cars and restart the operation of the cars and to notify the prescribed engine Do either one.

Further, more preferably, when a certain identical car reaches a car requiring inspection more than a predetermined number of times within a predetermined period, the notification means notifies the predetermined engine to that effect. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the configuration of a car lighting inspection system according to a preferred embodiment of the present invention. The target of inspection in the system shown in this figure is the fluorescent lamp 1 for illuminating the elevator car. Generally, a plurality of fluorescent lamps 1 are provided per car. A car lighting circuit 2 in the figure is a circuit including the fluorescent lamp 1 and its power source, and the control unit 3 turns on / off each fluorescent lamp 1 through signal transmission with the car lighting circuit 2 and turns on each fluorescent lamp 1. / Detects the off state. The control unit 3 is connected to a not-shown abnormality monitoring center via a communication line 4, and notifies the abnormality monitoring center as necessary to prompt the dispatch of a worker or an engineer.
The emergency light 5 in the figure is an illumination member for illuminating the inside of the car when the fluorescent light 1 is not normally turned on, and the emergency light circuit 6 is a circuit including the emergency light 5 and its power supply. The car drive unit 7 is a circuit that drives the elevator car, and the door drive unit 8 is a circuit that drives the door. The control unit 3 has a function of communicating with and controlling the emergency light circuit 6, the car driving unit 7, and the door driving unit 8. Although only one car lighting circuit 2 and the like are drawn in the figure, this is for simplification of the drawing, and this embodiment should be designed as a system for simultaneously inspecting a plurality of cars in parallel. You can

FIG. 2 shows a flow of operations of the control unit 3. The control unit 3 is in a state where the fluorescent lamps 1 are or are to be turned on, such as when the car is in operation (S
1) It is determined whether or not some of the fluorescent lamps 1 for illuminating the inside of the car are not normally turned on (S).
2). If there is a fluorescent lamp 1 that is not normally turned on in view of the temperature, current, etc. of the fluorescent lamp 1 monitored by the car lighting circuit 2, for example, if there is a fluorescent lamp 1 whose light quantity is significantly reduced, Consider the car with light 1 as a car requiring inspection. When the car requiring inspection is detected, the control unit 3 executes the operation of step S3 and thereafter. In step S3, it is determined whether or not all the fluorescent lamps 1 related to the detected car requiring inspection are not normally lit. If it is determined that all the fluorescent lamps 1 do not illuminate, that is, the inspection-required car, that is, the inspection-required car, the operation of the control unit 3 proceeds to step S17 described below.

When it is determined that the inspection-required car does not apply to all the inspection-required cars, the control unit 3
It is not necessary to make a call from the car (S4) and the door of the car is closed so that the user cannot enter the car (S5), that is, even if the fluorescent lamp 1 is turned off. After confirming that no one feels pleasant or anxious, a command is given to the car lighting circuit 2 to turn off the fluorescent lamp 1 related to the car requiring inspection (S6). After that, for example, 2
When ~ 3 seconds have elapsed (S7) and a call from the hall is further generated (S8), the control unit 3 gives a command to the car lighting circuit 2 to try to turn on the fluorescent lamp 1 related to the car requiring inspection ( S
9). After that, when a predetermined time, for example, several seconds to several tens of seconds have elapsed (S10), if all the fluorescent lamps 1 related to the inspection-required car are normally turned on (S11), the abnormality monitoring center is not notified, and the like. Return to step S1. Although not shown, the car drive unit 7 operates the car in response to the hall call in parallel with the relighting trial operation.

Therefore, if only a car requiring inspection temporarily reaches due to a drop in the power supply voltage or the like, re-lighting is automatically attempted and a normal lighting state, that is, lighting with sufficient illuminance is achieved. It will return to the state. In this automatic relighting trial, in order to prevent notification to the abnormality monitoring center even though the fluorescent lamp 1 does not need to be replaced,
It is valid. Further, since the turning-off and re-lighting trials of the fluorescent lamp 1 are performed in a state where there is no passenger in the car, the elevator user does not feel anxiety associated with the turning-off and re-lighting trials.

If it is determined in step S11 that one of the fluorescent lamps 1 is not normally turned on, that is, if the car still needs to be inspected in spite of the relighting attempt, the control unit 3 causes the control unit 3 shown in FIG. Perform the procedure shown in. In the procedure shown in FIG. 3, the control unit 3 adds 1 to the built-in software-like or hardware-like car lighting out counter (S12), and returns to step S1 shown in FIG. The car out of light counter is the step S shown in FIG.
11 is a counter that counts the number of times the car is judged to be in need of inspection, and if the count value of the car lighting out counter reaches a specified value through repetition of the procedure shown in FIGS. 2 and 3 (S13), the control unit 3 Executes notification to the abnormality monitoring center via the communication line 4 (S14). That is, a worker or a technician is dispatched to notify that the fluorescent lamp 1 or the car lighting circuit 2 should be inspected or investigated.
Then, the control unit 3 clears the illumination cut-out counter (S16). Also, if a predetermined period, for example, one week, has passed before the car lighting out counter reaches the specified value (S15), it is not due to the end of the life of the fluorescent lamp 1 but a temporary power supply voltage drop, etc. Since it can be considered that the determination has been made, the control unit 3 executes step S16 and clears the illumination cut-out counter.

As described above, the abnormality occurs only when the count value of the car lighting out counter reaches a specified value during a predetermined period, that is, when the car requires inspection a predetermined number of times during a predetermined period. Since the notification to the monitoring center is executed, it is possible to more accurately prevent the notification due to a temporary voltage drop or the like.

Further, when it is determined in step S3 shown in FIG. 2 that all the fluorescent lamps 1 related to the car are not normally turned on, that is, the car corresponds to a non-lighted car. If determined, the control unit 3 executes the procedure shown in FIG. In the procedure of this figure, the control unit 3 determines through communication with the car drive unit 7 whether or not the car is traveling (S17), and if the car is traveling, the car drive unit 7 is instructed to the car. Is stopped at the nearest floor (S18), and after the car is stopped at the nearest floor, the door of the car is opened through a command to the door drive unit 8 (S19). Thereafter, the control unit 3 turns off all the fluorescent lamps 1 related to the car according to a command to the car lighting circuit 2 (S20), and then waits a predetermined time, for example, about 2 to 3 seconds (S21), The car lighting circuit 2 is instructed to turn on each fluorescent lamp 1 (S22). After that, when a predetermined time, for example, several seconds to several tens of seconds has elapsed (S23), the control unit 3 determines whether or not all the fluorescent lamps 1 of the car have normally turned on (S24). When all the fluorescent lamps 1 have come to be turned on normally, the control unit 3 returns the car to a normal operating state (S25), and returns to step S1. On the contrary, the fluorescent lamp 1 of the car is turned off despite the light-off and re-lighting attempts executed in steps S20 to S22.
When any one of them is not normally turned on (S24), the control unit 3 shifts to the procedure shown in FIG.

As described above, with respect to the car that has reached the non-lighting car, the fluorescent lamp 1 is turned off and the relighting trial operation is executed after the door is stopped at the nearest floor and the door is opened. By doing so, it is possible to remove the occupant from the car prior to executing the turning-off and re-lighting trial operation, and therefore, it is less likely that the elevator user will feel uneasy with the turning-off and re-lighting trial operation. .

When it is determined in step S24 that one of the fluorescent lamps 1 is not normally turned on, if the abnormality monitoring center is notified in step S14 in FIG. 3, the abnormality monitoring center is notified. It is desirable to give a command to the emergency light circuit 6 at the same time as the above notification to turn on the emergency light 5. By doing so, it is possible to continue the operation of the car and ensure the function of the elevator until the worker or engineer is dispatched in response to the notification to the abnormality monitoring center. . When the emergency light 5 is used, the worker or technician to be dispatched knows in advance that the emergency light is being used by notifying the abnormality monitoring center to that effect as well in step S14. Therefore, it is possible to deal with it more flexibly and appropriately.

[0020]

As described above, according to the present invention, regarding a car requiring inspection that has a fluorescent lamp that does not light normally even though it is instructed to light, the fluorescent light related to the car when it can be considered that there is no passenger. Since the lamp is turned off and it is tried to be turned on again after a predetermined time, the relighting process is automatically executed for fluorescent lamps that have failed to be turned on due to a drop in power supply voltage or various accidents, or that have been turned off. Will be done. As a result, the relighting process is performed earlier than before without using the automatic turn-off after using the elevator (strictly speaking, that car), so the time when the illuminance in the car is decreasing It is possible to obtain the effect of shortening the work time and preventing unnecessary dispatch of workers and engineers.

Further, when the detected car to be inspected is a car to be inspected for all lights in which all the fluorescent lamps do not light normally even though the lighting is commanded, first stop at the nearest floor and open the door. By executing the turning-off and re-lighting trials after the car is opened, the occupant of the car can be removed from the car early, and the user's anxiety can be prevented or reduced.

Further, even if the light-off and re-lighting trials are executed because the car corresponds to the all-lights inspection required car, the car that still corresponds to the inspection-required car or the all-lights inspection required car is the emergency light of the car. By executing the process of turning on the light and restarting the operation of the car, it is possible to continue the operation of the car and maintain its function without waiting for the notification to the abnormality monitoring center and the dispatch of workers etc. in response to this. it can. In addition, prompt measures can be secured by merely notifying a predetermined organization, for example, the abnormality monitoring center, of that fact.
In addition, by performing the process of lighting the emergency light and restarting the operation, and performing the notification for a predetermined period together, the anomaly monitoring center side can make the situation more detailed while ensuring the operation of the car. You can know it, and you can handle it more accurately.

Then, when a certain car reaches the inspection-required car more than a predetermined number of times within a predetermined period, the fact is notified to a predetermined engine, that is, the situation is detected as the inspection-required car. By not sending a notification to the engine only when it occurs sporadically or sporadically, false notification to the engine or notification at an inappropriate time is prevented, and it is truly necessary to replace the fluorescent lamp etc. Only in such cases, the notification is given to the relevant organization, so that the reliability of the notification can be improved.
