Abstract

PURPOSE:To save labor for the work by automatically changing address information different at every shaft even on the same floor, informing changeover of the address information, recognizing changeover of the address information, and setting the address of a subordinate control part of a shaft. CONSTITUTION:When a cage 3 is returned to the uppermost floor, a common transmission line 11 is changed to an address set mode with a direct numerical control part 1A. Next, a maintenance engineer gets in the cage, stops it at a floor setting the address, after fully opening the door sounds the buzzer on the cage with a unit control part 2 by the direct numerical control part 1A for a certain time, and transmits the address 24 of a first shaft of the floor positioning the cage to the common transmission line 11. When the buzzer is stopped to sound, by pushing the call button 6 for the cage stop of the first shaft, a transmission station hall controller 5 as a subordinate control part of each cage stop receives the address data 24 transmitted to the common transmission line 11, and sets it as the address of its own unit.

2. Description of the Related Art A conventional technique will be explained with reference to FIG.

[0003] In response to input from the console 7 connected to the group management control unit 1A, the group management control unit 1A switches the common transmission line 11, which mainly transmits common platform calls, to address set mode. Next, the group management control unit 1A receives the car status data 2 input from the individual control unit 2 of the master car.
2, the address 24 of the first shaft of the car position floor of the master car is transmitted. This allows the transmission station hall controller 5, which is the slave control section of each landing, to set an address. The maintenance worker calls the master car to the floor where the address is to be set, and presses the landing call button 6 on the first shaft. When the hall call button 6 is pressed, the hall controller 5 receives the address data 24 transmitted to the common transmission line 11 and sets it as the address data of its own unit.

After the addresses of all the hall controllers of the first shaft have been set, the shafts are switched by input from the console 7 connected to the group management control section 1A, and the addresses of the second shaft are set in the same way as for the first shaft. be able to.

In this way, after the address setting of the Hall controllers of all shafts is completed, the group management control section 1A
The group management control section 1A switches the common transmission line 11 to the test transmission mode in response to an input from the console 7 connected to the group management control section 1A. The results of the test transmission are displayed on the console 7 for confirmation.

[0006]

In the prior art, maintenance personnel were required to return to the machine room and operate the console every time the address set for one shaft was completed. Test transmissions were also conducted in the machine room, and if there was a transmission error, it was necessary to set the address again. As a result, maintenance personnel had to take an elevator back and forth from the bottom floor to the top floor for at least several minutes in the shaft to go back and forth to the machine room.

[0007] The present invention provides an elevator group management control device that can save labor by making it possible to set the addresses of all hall controllers on a common transmission line at the car/boarding point without returning to the machine room. The purpose is to

[0008]

[Means for Solving the Problems] A group management control device, a single control device, a main transmission control section in the group management control device, a slave control section of each platform, and transmission address settings of the slave control section are set via a transmission line. A function performed by sending address information to each slave control unit, a means for automatically switching different address information for each shaft even on the same floor with the above configuration, a device and a means for notifying that address information is switched, and address information is switched. It is constituted by a device and means that recognizes this and sets the address of the slave control section of the corresponding shaft.

[0009]

[Operation] Even on the same floor, different address information for each shaft is automatically switched at regular intervals by the group management control device. Based on the information from the group management control device, the single control device notifies the change of address information using a notification device installed in the car. Further, the single control device detects the operation status of the operation switch in the car and sends a test transmission command to the group management control device. The group management control device switches the transmission system to test transmission in response to a test transmission command from the single control device. As a result, transmission error data is sent from the group management control device to the single control device, and the single control device displays it in the car.

[Embodiment] An embodiment of the present invention will be described with reference to the drawings. The configuration of an embodiment of the present invention will be explained with reference to FIG.

[0011] A group management control device 1, a single control device 2,
Notifies the group management control unit 1A in the group management control device, the main transmission control unit 1B, the hall controller 5 which is a slave control unit of each landing, the landing call button 6, and the car 3 that the address information will be switched. a car buzzer 10 used to perform maintenance; a door open button 9 used as a switch to switch the transmission system to test transmission from inside the elevator car; a car call button 8 used to register car calls and display test transmission results; A console 7 operates a command for switching to address set mode when a member of staff executes address set, and a break command for exiting address set mode. An embodiment of the present invention will be described using flowcharts shown in FIGS. 1 to 7.

Based on the input from the console 7 connected to the group management control unit 1A of the master machine, the group management control unit 1A:
Common transmission line 11 that mainly transmits common platform calls
It transmits to the unit control unit 2 that it is in the address set mode, and further outputs to the unit control unit 2 a command to return the car 3 to the top floor. The single control device 2 pulls the car 3 back to the top floor and makes it wait with the door open. Thereafter, until exiting the address set mode/test transmission mode, the unit control device 2 continues to open the door so that all doors are closed when the door is opened and the door will not close unless the door close button is kept pressed. This eliminates the need for maintenance personnel to operate the door opening button, and the work can be done by one person. When car 3 is pulled back to the top floor,
The group management control unit 1A switches the common transmission line 11 to address set mode.

Next, the maintenance worker gets on the car and calls the car to the floor where the address is to be set. After stopping at the destination floor and opening all doors, the group management control section 1A causes the single control section 2 to sound the buzzer on the car for a certain period of time, and transmits the address 24 of the first shaft of the car position floor to the common transmission line 11. When the buzzer stops ringing, maintenance personnel will press the platform call button 6 on the first shaft.
By pressing , the transmission station hall controller 5, which is a slave control section of each platform, receives the address data 24 transmitted to the common transmission line 11 and sets it as the address data of its own unit. After a certain period of time after the first buzzer sounds, the group management control unit 1A causes the single control unit 2 to sound the car buzzer again for a certain period of time, and
Send the shaft address 24 to the common transmission line 11. When the buzzer stops ringing, the maintenance worker presses the hall call button 6 of the second shaft to set the address of the hall controller 5 of the second shaft. In this way, the group management control unit 1A switches the address to be transmitted to the common transmission line 11 at regular intervals, and causes the single control device 2 to sound a buzzer each time the address is switched. This allows maintenance personnel to set the addresses of the hall controllers for all shafts on that floor.

[0014] After the maintenance staff completes the settings for all the hall controllers, he continues to press the door open button 9 inside the car for a certain period of time. The single control device 2 detects this and outputs it to the group management control section 1A. The group management control unit 1A switches the common transmission line 11 to test transmission mode. The main transmission control unit 1B performs test transmission and detects a transmission error, and the group management control unit 1A
Output to. The group management control unit 1A takes the logical sum of all the shafts in the transmission error table, converts it into data for each floor, and sends the converted transmission error data to the single control device 2, which outputs it to the car call button 8 in the car 3. .

If a test transmission is performed and there is a transmission error, the group management control unit 1A puts the common transmission line into address set mode again. If there is no transmission error, return to normal.

If the maintenance person wishes to stop address setting, the group management control section 1A switches from the address set mode to the normal mode in response to an input from the console 7 connected to the group management control section 1A of the master machine.

[0017] By making it possible to set the addresses of all the hall controllers on the common transmission line at the car/boarding area without returning to the machine room, it is possible to save labor.

[0018] Furthermore, since the switch for switching to the test transmission mode is the door open button, the transmission error is indicated by the car call button, and the shaft change notification is performed by the buzzer on the car, it is necessary to specially install equipment for address setting. There isn't.

In this embodiment, a sound generation device is used as an example of a means for notifying that an address is switched, but the present invention is not limited to this. It is obvious that the car call registration lamp, hall lantern, hall chime, etc. on the in-car operation panel can be handled in the same way.

[0020]

[Effects of the Invention] By making it possible to set the addresses of all the hall controllers on the common transmission line at the car/boarding point without returning to the machine room, it is possible to save labor. This is especially effective when an emergency elevator is included in a building with a face-to-face configuration or a group control unit, since the number of shafts increases and the number of slave control units per floor increases.
