Description

The present invention relates to a control device for an elevator which can be disabled contact information when the hall button is pressed.

  Elevator diagnostic operation, which actually operates the elevator and periodically diagnoses various devices, is reserved during times when there are no elevator users or when there are few users. To be implemented. However, when a landing call is registered by an elevator user or the like pressing a landing button during diagnostic driving, it is common to give priority to the convenience of the user and interrupt the diagnostic driving and respond to the landing call. It is.

  In addition, simulated diagnosis operation that performs the same operation as the above-described diagnosis operation by inputting a command from a portable maintenance terminal device possessed by an elevator maintenance worker is a device or maintenance personnel having an abnormality found by the diagnosis operation. This is done to check the operation of the equipment replaced by In addition, the simulated diagnosis operation cannot be reserved in advance in a time zone with a small number of users like the above-described diagnosis operation, and is generally appropriately performed when an abnormality of the device is discovered by the diagnosis operation. . Similarly to diagnostic driving, if a hall call is registered by an elevator user pressing a landing button during simulated diagnostic driving, priority is given to the convenience of the user, etc. It is common to answer a call.

  As a conventional technique for prohibiting registration of hall calls during diagnostic operation, speed selection means for selecting the operation mode of the elevator at the time of diagnostic operation as either low speed or high speed according to a command from a diagnostic device that performs the diagnostic operation of the elevator And a call prohibiting means for prohibiting a response to a hall call when the low speed operation mode is selected (for example, see Patent Document 1).

In addition, when the pressing information of the door closing button 7 is detected by the elevator operation control unit 6, a door closing command is output from the elevator operation control unit 6 to the door opening / closing control unit 9. The door opening / closing control unit 9 performs door closing control based on the door closing command input from the elevator operation control unit 6. When the elevator operation control unit 6 detects the pressing information of the door opening button 8, a door opening command is output from the elevator operation control unit 6 to the door opening / closing control unit 9. The door opening / closing control unit 9 performs door opening control based on the door opening command input from the elevator operation control unit 6.

  Reference numeral 10 denotes an operation mode changeover switch operated mainly by an elevator maintenance person to switch the elevator operation mode to the fully automatic operation mode or the independent operation mode. Reference numeral 11 denotes the contact information of the operation mode changeover switch 10. And an operation mode selection unit that selects one of the two modes as the operation mode of the elevator. In addition, the operation mode of an elevator is demonstrated below.

  When the operation mode changeover switch 10 is switched to the fully automatic operation mode side by an elevator maintenance person or the like, the operation mode selection unit 11 performs the call information control unit 5 and the elevator operation control based on the contact information of the operation mode changeover switch 10. A mode signal indicating that the fully automatic operation mode is selected is output to the unit 6. Note that the fully automatic operation mode is an operation mode in which the user only registers the car call and the hall call, and the car is automatically moved to the registered floor, and the doors are opened and closed automatically. Even if there is no operator, the elevator automatically starts operation if registration of call information can be performed automatically or manually. Specifically, the following control is performed.

  When a mode signal indicating that the fully automatic operation mode is selected from the operation mode selection unit 11, the call information control unit 5 permits the destination button detection unit 2 and the landing button detection unit 4 to detect call information. Output a signal. The destination button detection unit 2 receives contact detection signals from the call information control unit 5, detects contact information when the destination button 1 is pushed by an elevator user, etc., and calls a registered car call. Output to the information control unit 5. On the other hand, the landing button detection unit 4 detects contact information when the landing button 3 is pushed by an elevator user or the like by receiving a detection permission signal from the call information control unit 5 and registers the registered landing call Is output to the call information control unit 5. The call information control unit 5 to which the call information is input from the destination button detection unit 2 or the landing button detection unit 4 stores the input call information and outputs the stored call information to the elevator operation control unit 6. . When the call information is input from the call information control unit 5, the elevator operation control unit 6 determines the driving direction of the car based on the current position of the car and the input call information, and runs the car to the registration floor. Let When the car arrives at the registration floor, the elevator operation control unit 6 outputs a door opening command to the door opening / closing control unit 9, and the door opening / closing control unit 9 performs a door opening operation. Moreover, the elevator operation control part 6 cancels | releases the door opening command output with respect to the door opening / closing control part 9, and outputs a door closing command after predetermined time progress from door full opening. The door opening / closing control unit 9 performs a door closing operation based on a door closing command from the elevator operation control unit 6.

  In addition, during the fully automatic operation mode, the elevator operation control unit 6 outputs the door opening command to the door opening / closing control unit 9 after landing on the registered floor as described above, while the car is in the door openable position stop state. A door open command is output only when pressing information of the open button 8 is detected. Therefore, the elevator operation control unit 6 always issues a door closing command to the door opening / closing control unit 9 when the pressing information of the door opening button 8 is not detected even when the car is stopped at the door opening possible position. Output.

  On the other hand, when the operation mode changeover switch 10 is switched to the independent operation mode side by an elevator maintenance person or the like, the operation mode selection unit 11 is connected to the call information control unit 5 and the elevator operation based on the contact information of the operation mode changeover switch 10. A mode signal indicating that the independent operation mode is selected is output to the control unit 6. In addition, the independent operation mode is an operation mode that is performed by the operation in the car except for the traveling of the car to the registered floor and the door opening operation under a certain condition, and an operator is always required in the car. Specifically, the following control is performed.

  When the mode signal indicating that the independent operation mode is selected from the operation mode selection unit 11, the call information control unit 5 outputs a car call detection permission signal to the destination button detection unit 2, and the landing button A hall call detection non-permission signal is output to the detection unit 4. The destination button detection unit 2 receives contact detection signals from the call information control unit 5, detects contact information when the destination button 1 in the car is pushed by an elevator user, and the registered car. The call is output to the call information control unit 5. The call information control unit 5 to which the car call is input from the destination button detection unit 2 stores the input car call and outputs the stored car call to the elevator operation control unit 6. The hall button detection unit 4 does not detect contact information when the hall button 3 is pushed by an elevator user or the like when a detection non-permission signal is input from the call information control unit 5. When a car call is input from the call information control unit 5, the elevator operation control unit 6 determines the driving direction of the car based on the current position of the car and the input car call. Further, the elevator operation control unit 6 outputs a door closing command to the door opening / closing control unit 9 by detecting the pressing information of the door closing button 7 installed in the car after the driving direction of the car is determined, After the door is closed, run the car to the registered floor. When the car arrives at the registration floor, the elevator operation control unit 6 outputs a door opening command to the door opening / closing control unit 9, and the door opening / closing control unit 9 performs a door opening operation.

  In addition, during the independent operation mode, the elevator operation control unit 6 determines whether the car driving direction is determined and the door opening / closing control unit 9 is operated with respect to the door opening / closing control unit 9 only when pressing information of the door closing button 7 is detected. Outputs a close command. Therefore, even when the car is stopped at the door openable position, the elevator operation control unit 6 always outputs a door open command to the door open / close control unit 9 unless the above state is recognized.

  Reference numeral 12 denotes a maintenance mode switch which is mainly operated by an elevator maintenance person to switch the elevator operation mode to the normal operation mode or the maintenance mode, and is mounted on the elevator CPU card. The maintenance mode is an operation mode that is selected when the maintenance staff of the elevator performs maintenance work, and the operation of the elevator itself is almost the same as the normal operation mode, but it falls into a state that is considered to be abnormal during the normal operation mode. However, it is controlled so that an abnormality report or the like is not performed, assuming that maintenance personnel are performing maintenance work. For example, in an elevator equipped with a remote monitoring system, if the car stops between the stop floor and the stop floor during the normal operation mode, report to the monitoring center that monitors the elevator that an abnormality has occurred However, if it is in the maintenance mode, the monitoring center or the like is not notified that the maintenance work is in progress. There are also functions related to maintenance that operate only in the maintenance mode.

  Reference numeral 13 denotes a maintenance terminal device that is connected to the elevator by wire or wirelessly during maintenance work, and 14 is provided in the maintenance terminal device 13. A landing call disapproval command unit 15 for outputting a landing call disapproval command to prevent registration of the call, 15 analyzes various signals input from the maintenance terminal device 13, and the call information control unit 5 and the elevator operation A terminal device signal analysis unit 16 for outputting the analysis result to the control unit 6 is provided in the terminal device signal analysis unit 15, and a landing call is not permitted from the landing call disapproval command unit 14 in the maintenance terminal device 13. It is a hall call rejection determination unit that determines whether registration of hall calls is not permitted when a permission command is input.

  Next, an operation for preventing registration of a hall call from the maintenance terminal device 13 will be described with reference to FIG. The maintenance staff of the elevator connects the maintenance terminal device 13 to the elevator and outputs a landing call non-permission command from the landing call non-permission command unit 14 (step S201). When the hall call refusal instruction is input to the terminal device signal analysis unit 15, the hall call refusal determination unit 16 determines whether to prohibit registration of the hall call. Here, when the operation mode is the normal operation mode (step S202), the hall call disapproval determination unit 16 determines that the hall call is permitted in order to respond to the hall call registered by the elevator user ( Step S206). On the other hand, when the operation mode is switched to the maintenance mode by the maintenance mode switch 12 in advance (step S202), the hall call rejection determination unit 16 prevents registration of the hall call during simulated diagnosis operation and performs maintenance work. In order to perform smoothly, it is determined that the hall call is not permitted (step S203).

  When it is determined that the hall call is not permitted by the hall call rejection determination unit 16, a terminal call rejection signal is output from the terminal device signal analysis unit 15 to the call information control unit 5. The call information control unit 5 outputs a hall call detection non-permission signal to the hall button detection unit 4 when the hall call non-permission signal is input. In such a case, the hall button detection unit 4 does not detect contact information when the hall button 3 is pushed by an elevator user or the like. Since the call permission control unit 5 outputs a detection permission signal to the destination button detection unit 2, the car call registered by the destination button 1 is detected by the destination button detection unit 2, and the call information control unit 5 is stored. Therefore, the elevator maintenance worker selects the fully automatic operation mode in such a state and performs the simulated diagnosis operation.

  In addition, when the registration of the hall call is not permitted by outputting the hall call non-permission command from the maintenance terminal device 13, the maintenance staff operates the maintenance mode switch 12 when permitting the registration of the hall call again. Then, the maintenance mode is canceled (step S204), or the landing call disapproval cancel command is output from the landing call disapproval command unit 14 of the maintenance terminal device 13 (step S205). When the maintenance mode is canceled by operating the maintenance mode switch 12, the call information control unit 5 outputs a detection permission signal to the hall button detection unit 4. On the other hand, when a landing call non-permission cancellation command is output from the maintenance terminal device 13, a landing call non-permission cancellation signal is output from the landing call non-permission determination unit 16 to the call information control unit 5, and the call information control unit 5 outputs a detection permission signal to the hall button detection unit 4.

  In the first embodiment, the call information control unit 5 sends a detection non-permission signal to the hall button detection unit 4 when the hall call non-permission determination unit 16 determines that registration of the hall call is not permitted. Is output so that the contact information when the landing button 3 is pressed is not detected, but the landing call detected by the landing button detection unit 4 is determined as call information when the landing call registration is not permitted. You may control not to memorize | store in the control part 5. FIG. That is, when it is determined that the landing call registration is not permitted by the landing call rejection determination unit 16, the contact information when the landing button 3 is pressed is invalidated before being input to the elevator operation control unit 6. If you can.

  According to the first embodiment of the present invention, the contact point information when the landing button 3 is pressed during the maintenance mode can be invalidated by the landing call non-permission instruction from the maintenance terminal device 13. The simulated diagnosis operation is not interrupted by the hall call by the user, and the simulated diagnosis operation can be performed in a fully automatic operation mode that does not require an operator in the car. In addition, the hall call refusal determination unit 16 in the maintenance terminal device 13 cancels the hall call ban function that invalidates contact information when the hall button 3 is pressed, and the hall call ban function. Since it has a hall call disapproval cancellation function that validates contact information when the hall button 3 is pressed, it is excellent in operability and workability during maintenance work, and shortens the time required for maintenance. Is possible. In addition, since the hall call is not registered, it is possible to make the elevator user aware of the fact that the elevator is being checked, and it is also possible to prevent confinement and disaster due to the user getting in during the simulated diagnosis operation.

It is a block diagram of the control apparatus of the elevator in Embodiment 1 of this invention. It is a flowchart which shows operation | movement of the control apparatus of the elevator in Embodiment 1 of this invention.
