Description

  The present invention relates to an elevator control apparatus for realizing an efficiency of an elevator cleaning operation during a maintenance inspection operation.

  The method of cleaning an elevator by an elevator maintenance worker or a cleaning worker (hereinafter collectively referred to as a maintenance cleaner) is roughly classified into cleaning in a normal operation state and cleaning in an operation state dedicated to cleaning.

(1) Cleaning in a normal operation state In this method, since cleaning is performed during a normal operation, it is used in combination with a general user. As a result, the general user may feel uncomfortable, or conversely, the general user may be in the way and the efficiency of the cleaning operation may be reduced.

  In cleaning in a normal operation state, there is a method of raising a bill such as during cleaning so that it is not used by general customers. However, in an elevator in which a plurality of vehicles are group-controlled, an elevator that performs a cleaning operation is also assigned to the hall call. For this reason, a general driving elevator and a cleaning elevator cannot be separated.

  Furthermore, since it is used together with general users, the car door or the landing door may open and close when the maintenance cleaner does not intend. For this reason, when cleaning the door of the car or the door of the landing, there is a risk of being drawn into the door.

(2) Cleaning in the operation state dedicated to cleaning Among the elevators under group control, there are those that perform cleaning in dedicated operation that does not respond to hall calls by removing the elevator to be cleaned from group control. Yes (see, for example, Patent Document 1). By performing such a dedicated operation, it is possible to solve the problem of cleaning in the normal operation state.

[Mode 2] Car side door cleaning: This mode allows the car side door to be cleaned and the vicinity of the door tip to be cleaned by one person based on an operation from within the car.
[Mode 3] Implementation of movement to another floor: In this mode, the cleaning work can be continued by moving to another floor by one person based on an operation from within the car.

  The elevator control unit 10 is determined in advance so that the operation of the door opening button 2, the door closing button 3, and the plurality of destination buttons 4 provided on the in-car operation panel 1 and modes 1 to 3 can be selected. Based on the result of comparison with the operating procedure, cleaning work in a desired mode is made possible.

  First, the switching operation of modes 1 to 3 will be described with reference to FIG. If the elevator control unit 10 is in the door open state and the cleaning switch 5 is switched to the “operation” side, the elevator control unit 10 switches the elevator to fully automatic operation and ends the cleaning operation mode (steps S401 to S403).

  On the other hand, if the cleaning operation mode is still selected, the mode is switched to one of modes 1 to 3 based on the operation from the car (steps S404 to S406), and each mode is selected to perform the cleaning work. (Steps S500, S600, S700).

Then, about the specific selection method of mode 1 to mode 3 in the present invention, [mode 1] selection of landing side door cleaning to be described below. After pressing the destination button 4 to the floor of the operation panel 1 in the car shown in 2, the door close button 3 is pressed. When the elevator control unit 10 is in a standby state in which the door is fully opened and the door closing button 3 is pressed after the destination button 4 to the floor is pressed in the cleaning operation mode, the elevator control unit 10 executes the mode 1. In order to do this, the series of processing shown in FIG. 5 is performed.

  The elevator control unit 10 starts a door closing operation after a designated time limit a seconds (for example, 4 seconds) has elapsed, and sets the door to a fully closed state (step S501). The maintenance cleaner moves from the car to the landing during a second (that is, before the door closing operation starts), and starts the cleaning operation after the door is fully closed (step S502).

  Next, the elevator control unit 10 maintains the fully closed state for a predetermined time period b (for example, 3 minutes), and automatically opens the door after the predetermined time period b has elapsed (steps S503 and S504). . The maintenance cleaner can easily clean the door on the landing side during the predetermined time period b in which the fully closed state is maintained, and, after the predetermined time period b has elapsed, can get into the car from the automatically opened door.

  The elevator control unit 10 starts a door closing operation (step S601). Then, the elevator control unit 10 continues the door closing operation as long as the door closing button 3 is continuously pressed by the maintenance cleaner (steps S602 and S603). Further, when the door is fully closed as a result of the door closing button 3 being continuously pressed, the elevator control unit 10 maintains the fully closed state (steps S604 and S605). The maintenance cleaner cleans the car side door while the door is fully closed (step S606).

  On the other hand, if it is determined in the previous step S602 that the door closing button 3 is not pressed before the door is fully closed, the elevator control unit 10 stops the door at the current position and sets the half-open state. Maintain (step S607). Accordingly, the maintenance cleaner easily stops the periphery of the front end of the landing door that has been half-opened at the desired position by stopping the pressing of the door-close button 3 at the desired position before the door is fully closed. It can be cleaned (step S608).

  Next, the elevator control unit 10 determines whether or not the maintenance cleaner has pressed the door opening button 2 or the door closing button 3 after the cleaning operation in step S606 or step S608 is completed (steps S609 and S610). If the elevator control unit 10 determines that the door opening button 2 has been pressed, the elevator control unit 10 starts the door opening operation, sets the door in a fully open state (step S611), and ends the series of processes. On the other hand, if the elevator control unit 10 determines that the door opening button 2 has been pressed, the process returns to the previous step S601 and the subsequent processing is continued.

  FIG. 8 is an explanatory diagram of a cleaning operation when car side door cleaning is selected in the elevator control device according to Embodiment 1 of the present invention. FIG. 8 illustrates a case where the landing-side door 31 and the car-side door 32 are each composed of two pieces (31a, 31b, and 32a, 32b). Further, FIG. 8A shows a state where the door is half open and is stationary (corresponding to the state of step S607), and FIG. 8B shows a door open button from the state of FIG. 2 shows a state where the fully open state is maintained (corresponding to the state in step S611).

  By selecting the car side door cleaning according to the mode 2, the maintenance cleaner can perform the peripheral portion 30 of the front end of the door in the half-open state in FIG. 8A and the full-open state in FIG. The car-side door 32 can be easily and efficiently cleaned by one person.

[Mode 3] Selection of movement to another floor When selecting mode 3, the maintenance cleaner keeps pressing the destination button 4 other than the own floor on the car operation panel 1 shown in FIG. When the elevator control unit 10 is in a standby state where the door is fully opened, and determines that the destination button 4 other than the own floor is kept pressed in the cleaning operation mode, the elevator control unit 10 performs the mode 3 in FIG. Perform the series of processes shown.

  After fully closing the door, the elevator control unit 10 causes the elevator to travel to the pressed destination button floor 4 (step S701). Furthermore, after the elevator arrives at the destination floor, the elevator control unit 10 starts the door opening and makes it fully open (step S702). Thereafter, the processing after step S401 shown in FIG. 4 is performed. Thereby, the maintenance cleaner can clean the door on the landing side on another landing floor.
