  In the elevator, the destination floor is determined by the hall button 5 shown in FIG. 1 or the destination floor button installed in the car operation panel 4, and the microcomputer 10 in the control panel compares the start position signal and the stop signal with the car position data. A rise signal, a fall signal, a speed command, etc. are generated. Based on these signals, a drive command for the hoisting machine is generated.

  In addition, 11 is a landing side door of the elevator hall, and 12 is a rotary encoder that detects the rotation of the deflector.

  FIG. 2 is a functional block diagram of an elevator crime prevention operation apparatus according to an embodiment of the present invention, and particularly shows a means having a detection, determination or processing function in the control panel 7. As shown in FIG. 2, based on the short operation time of the emergency call button such as an intercom button detected by the emergency call button operation time detecting means 71, the nearest floor stop or communication connection determining means 72 Judgment of floor stoppage or communication connection. Based on the result, the nearest floor stop processing means 73, door opening / closing processing means 74, or communication connection processing means 75 connects the communication path with the intercom in the manager room or the monitoring room 8.

  FIG. 3 is a schematic configuration diagram of an elevator crime prevention operation apparatus according to an embodiment of the present invention. In particular, it is shown as a means having a detection, judgment or processing function in the control panel 7. As shown in FIG. 2, the elevator performs operation control by giving a drive command to a hoisting machine, a door, or the like from an elevator operation control unit 31 provided on the control panel 7. Based on the information of the destination floor 34 determined by the car call 32 and the hall call 33 and the car position data 35, the elevator operation control unit 31 determines the driving direction and speed of the car. Thereby, a drive command is sent from the elevator operation control unit 31 to the hoisting machine drive control unit 36, and the car 1 is moved to the destination floor. After the car 1 stops on the destination floor, a drive command is sent to the door opening / closing control unit 37 to open and close the door.

  In the present embodiment, the “closest floor stop or communication connection” determination unit 38 is provided in the control panel 7. This “closest floor stop or communication connection” determination unit 38 determines whether the nearest floor stop or communication connection is made based on the operation time of the emergency call button 40 measured by the timer 39 and the operation state data 41. I do. Based on the determination result information by the “closest floor stop or communication connection” determination unit 38, whether the elevator operation control unit 31 stops the nearest floor or causes the communication connection control unit 42 to perform communication connection, this embodiment Function can be achieved.

  FIG. 4 is a flowchart of an operation control process according to an embodiment of the present invention.

  Hereinafter, specific crime prevention operation of the elevator will be described with reference to FIGS. 3 and 4.

  Since the present embodiment is based on the assumption that the vehicle is in normal operation, first, in the “closest floor stop or communication connection” determination unit 38 in FIG. Alternatively, it is determined whether various control operations are being performed (step 401). In the case of various control operations, since the various control operations have priority, the current control operation is continued (step 402). If it is determined in step 401 that the normal operation is being performed, the process proceeds to step 403. When the passenger in the car operates the emergency call button 40 during normal operation, the operation time of the emergency call button 40 detected by the timer 39 is compared with a predetermined time (for example, 1 second), and the nearest floor is stopped. It is determined whether a communication connection is to be made (step 404). When the operation time of the emergency call button 40 exceeds the predetermined time, the communication circuit which is a normal emergency call button call response is connected (step 405). Therefore, if the passenger wants to perform a normal emergency call button call response during normal operation, the passenger may operate the emergency call button for a predetermined time or more. When this communication circuit connection is completed (step 406), normal operation is continued (step 407).

  The operation time of the emergency call button 40 is compared with a predetermined time (step 404), and if the operation time of the emergency call button 40 is only a short time within the predetermined time, the emergency call button or emergency room is immediately A notification is made (step 408), and the elevator is stopped at the nearest floor at the same time. Therefore, if the passenger encounters a crime or wants to stop the elevator at the nearest floor during normal operation due to an emergency situation, the emergency call button may be operated shortly.

  Thus, when the emergency call button is operated only for a short time, the elevator operation control unit 31 takes the nearest floor stop and door opening / closing process according to the following procedure.

  First, it is determined whether or not the elevator is running based on the driving state data 41 (step 409). If the elevator is running, the floor (the nearest floor) that can arrive in the shortest time from the current car position is determined. Move and stop (step 410). The door is opened while the elevator is stopped (step 411), and the passenger is evacuated out of the car. After elapse of a predetermined time (for example, 20 seconds) sufficient for the passenger to evacuate outside the car (step 412), the door is closed (step 413), and then normal operation is resumed (step 407).

  When it is detected that the emergency call button has been operated only for a short time, if it is determined in step 409 that the car 1 is stopped, the process jumps to step 411, immediately opens the door, Allows escape.

  As described above, according to the present embodiment, the operation time of the existing emergency call button is counted, and it can be easily applied to an existing elevator only by adding a software process only for comparison with a threshold value. In addition, it is possible to provide an elevator crime prevention operation device that is less likely to be erroneously operated.
