The operation process according to the present invention configured as described above will be described in detail with reference to FIGS. 6 to 9.

First, when the installer currently sets the mode of the elevator control apparatus 100 to the identification ID input mode through the unique ID acquisition switch 103 in order to set the automatic ID, the unique ID acquisition switching unit set to the identification ID input mode. The 103 transmits the unique ID acquisition mode data to the main transmission / reception device 120 through the communication line 110, and the main transmission / reception device 120 controls a plurality of holes through the common line 130. It transfers to the devices 140 to 160 to switch the mode of the hall control devices 140 to 160 from the normal elevator driving mode to the identification ID input mode.

After this setting is completed, the installer sequentially presses the registration buttons 140c to 160c which transmit unique IDs in the hall control devices 140 to 160 installed on each floor while traveling in an elevator.

Here, when the installer presses the registration button 140c, the hall control processing unit 143 in the hall control device 140 received through the input / output unit 144 receives the unique ID from the unique ID storage unit 145. The controller 146 reads the data and transmits it to the transceiver 141, and the transceiver 141 transmits the unique ID to the main transmission / reception apparatus 120 through the common line 130.

In this order, when the installer sequentially presses the unique ID transmission buttons 140c to 160c in the plurality of hall controllers 140 to 160, the unique IDs are sequentially input from the plurality of hall controllers 140 to 160. Therefore, the elevator control apparatus 100 stores the sequentially input unique ID, the absolute floor information and setting information at that time in the unique ID storage unit 104 and identification ID storage unit 105.

Then, when the operation of storing the unique ID transmission and received unique ID for the entire hall control device 140 to 160 in the unique ID designation station 105 is completed, the installer is the unique ID acquisition switching unit 103 End the unique ID acquisition mode through.

Thereafter, when the elevator control apparatus 100 is switched to the automatic ID setting mode, the automatic ID to be set on each floor is set based on the unique IDs, the absolute floor information, and the setting information of the plurality of stored hall control devices 140 to 160. do.

First, if the unique ID of the hall control device 140 is the first unique ID, the identification ID transmission unit 106 in the elevator control device 100 is the unique ID storage unit 104 and identification ID storage unit 105 The first unique ID, the absolute layer information, and the setting information stored in the main line are output to the common line 130 through the main transmission / reception device 120.

In addition, the plurality of hall controllers 140 to 160 receiving the received IDs compare their own IDs with the received IDs, and the ID ID controllers 147 in the hall control apparatus 140 having the same IDs. Stores the absolute layer information and the setting information input through the transceiver unit 141 in the identification ID storage unit 148.

In addition, the identification ID transmission unit 106 in the elevator control apparatus 100 increases the absolute floor information by 1 so that the second unique ID stored in the unique ID storage unit 104 and the identification ID storage unit 105 is absolute. The floor information and the setting information are output to the common line 130 through the main transmission / reception device 120, and the plurality of hall control devices 140 to 160 receiving the same are compared with the unique IDs they have. The identification ID storage unit 148 stores the absolute layer information and the setting information.

When the elevator control apparatus 100 performs these operations sequentially, the elevator control apparatus 100 operates the elevator in the normal elevator driving mode.

As described in detail above, the present invention automatically communicates a plurality of hall controllers in the elevator controller by serially communicating unique ID, absolute floor information, and setting information through a common line between the elevator controller and the plurality of hall controllers. By identifying, there is an effect of minimizing the installation time and cost of the hall control device, and at the same time to prevent errors during installation.
