Abstract

PURPOSE:To improve the electricity saving effect of a cage internal illumination without reducing the service to elevator users by judging the utilizing frequency of an elevator by the frequency of call registration, setting the cage internal illumination to the shortest time from the generation of a final call, and then extinguishing the illumination. CONSTITUTION:A counter 11 for counting the frequency of cage call and hall call is provided, and an extinguishment waiting time selecting circuit 12 for cage internal illumination and a cage internal illumination extinguishing circuit 13 are also provided. The counter 11 counts the frequency of cage call and hall call for a determined time from the point of time when a call is registered, and when the counted value does not reach a determined value, it outputs an early extinguishment signal. Namely, when the utilizing frequency is high, the illumination is extinguished when the next call is not generated with a relatively long waiting time from the generation of the final cage call or hall call, and when the utilizing frequency is low, it is similarly extinguished with a relatively short waiting time. Thus, the electricity saving effect can be enhanced without reducing the service to the users of the elevator.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to an elevator car interior lighting control device that is equipped with a light extinguishing means for saving power for elevator car interior lighting.

(Prior Art) The lighting inside an elevator car is usually turned on and off by a light switch provided on an operation panel inside the car.

In addition, a system has been proposed in which the lights are automatically turned off to save power when the number of elevator users stops and the call registration waiting time becomes long. In that case, the condition for turning off the lights is generally that there is no car call or hall call even after a certain period of time, for example about 15 minutes, has elapsed since the last car call or hall call was registered. many.

FIG. 3 is a flowchart of the automatic lights-off portion in a conventional lighting control device equipped with such an automatic lights-off device. Whether or not the car interior light is on (step 531)
), if the lights are on, it is determined whether a predetermined period of time, for example, about 15 minutes, has elapsed since the last car call or landing call occurred (step 532), and if so, the car interior lights are turned off. If the elapsed time has not elapsed (step 833), the in-car lighting remains on (step 534). If the in-car light is not on, check whether a car call or hall call has occurred (step 535), and if so, turn on the in-car light (step 534); if not, check to see if a car call or hall call has occurred. The car interior lighting remains off (step 536).

(Problem to be Solved by the Invention) As described above, in the conventional automatic lights-off device that turns off the lights inside the elevator car to save electricity, even after a certain period of time has elapsed since the last car call or hall call was registered, In addition, the lights are turned off under the condition that there are no car calls or hall calls, or the time is set uniformly even when the elevator is used relatively frequently or when it is used infrequently.
Even though it is possible to save electricity by turning off the lights inside the car in a short time after the final call registration, such as at night when the car is not used often, it takes a longer time than necessary to turn off the lights. As a result, electricity was wasted.

The present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide an elevator car interior lighting control device that can more rationally improve the power saving effect without significantly deteriorating the service to elevator passengers. With the goal.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the elevator car lighting extinguishing control device of the present invention counts the number of car calls and hall calls for a predetermined period of time from the time of call registration, and calculates the count value. a counting means for outputting an early light-off signal when the signal does not reach a predetermined value, and a first signal that is relatively short from the time of the last car call or hall call, provided that the early light-off signal is output from the counting means. When there is no next car call or hall call after the waiting time has elapsed, an early lights-off signal is not output from the first lights-off control means that issues a lights-off command to turn off the lights inside the car, and from the counting means. A lights-off command for turning off the lights inside the car when there is no next car call or hall call even after a relatively long second waiting time has elapsed from the time of the last car call or hall call. and a second lights-out control means for outputting the light.

(Function) According to the above configuration, the frequency of use of the elevator is determined based on the car call or hall call, and when the frequency of elevator use is high, the waiting time is relatively long from the time when the last car call or hall call occurs. When there is no next call, the light is turned off, and when the use frequency is low, the light is turned off after a relatively short waiting time. In this way, power saving effects can be achieved without significantly degrading service to elevator users.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an embodiment of the present invention.

The apparatus shown in FIG. 1 is provided with a counter 11 for counting the number of car calls and hall calls.

The counter 11 is newly started by the call registration signal Ty generated at the time of call registration, and counts the number of times the car call signal Yk and the hall call signal Yn are generated for a predetermined period of time. Then, when the count value does not reach a predetermined value within a predetermined time, the counter 11 sends an early light-off signal St.
- Early light-off signal St that outputs “1” and invalidates early light-off when the count value reaches a predetermined value within a predetermined time.
- Sends “0” to the in-car lighting turn-off standby time selection circuit 12. That is, the counter 11 counts the number of car calls or hall calls within a predetermined period of time based on the time when call registration is performed based on the car call or hall call, and counts the number of car calls or hall calls until the number reaches a predetermined value. In the latter case, it is determined that the elevator is used frequently, and if the predetermined value has not been reached, it is determined that the elevator is used infrequently. - Output “1”. Note that the settings of the count time and full count value of the counter 11 for determining the frequency of use of the elevator can be adjusted or changed as desired.

The in-car lighting turn-off standby time selection circuit 12 sets a relatively short standby time, for example, 5 minutes, in order to turn off the lights early to save power when the early turn-off signal St-“1” is received.
If there is no next car call or hall call even after a waiting time of 5 minutes has elapsed since the last car call or hall call, a light-off command is issued to the car interior light extinguishing circuit 13. Turn off the lights (not shown). When the early light-off signal St-“0” is determined, it is determined that there is a relatively high demand for elevators, and the waiting time is relatively long, for example, 15
minutes, and only when there is no next car call or hall call after a waiting time of 15 minutes has elapsed since the occurrence of a car call or hall call, a light-off command is issued to the car illumination turn-off circuit 13. to turn off the lights inside the car.

The counter 2 of the apparatus shown in FIG. 1 and the interior lighting turn-off standby time selection circuit 2 are constituted by, for example, a microcomputer.

The operation of the apparatus shown in FIG. 1 will be explained below with reference to the flowchart shown in FIG.

First, check whether the car interior lights are on or not (step 521). Once it is confirmed that the car lights are on, next, a hall call or car call has occurred more than a predetermined number of times within a predetermined time from the time of the last call registration. whether the early light-off signal St output from the counter 11 is 1'' or 0.
(Step 522).St-“0” means that the frequency of elevator use is relatively high, so the waiting time is relatively long (15 minutes) from the time the car call or hall call occurs. After the car call or hall call has passed, the car interior lights are turned off (step 823).In addition, since St-1 is a case where the elevator usage frequency is relatively low, the relative After a relatively short waiting time (5 minutes) has elapsed, the car interior lighting is turned off (step 524). When it is confirmed in step S21 that the light is off, the state continues until there is a new car call or hall call. In other words, it is checked whether a car call or a landing call has occurred (step 525), and if it is confirmed that no car call or hall call has occurred, the lights are continued to be turned off (step 5).
26) Immediately when a car call or a hall call occurs, the interior lights of the car are turned on (step 527) and the car is placed on standby for passengers to board.

As described above, if the elevator is used frequently, by turning off the lights after a relatively long waiting time when the last car call or landing is called, it is possible to avoid service deterioration and save power, and to save electricity overnight. If the system is used infrequently, the lights will be turned off after a relatively short waiting time when the last call is made or the boarding area is called, resulting in even greater power savings.

〔Effect of the invention〕

As described above, according to the present invention, the frequency of use of the elevator is determined based on the number of calls registered, and when the frequency of use is high, the lighting inside the car is turned off after a long period of time from the occurrence of the last call, and When the usage frequency is low, the light is turned off after a short set time. In this way, the power saving effect of the in-car lighting can be improved without deteriorating the service to elevator customers.
