The embodiment of the present invention provides an elevator serial communication cable, which includes a power line, a communication line and a plurality of address lines.

Among them, the power cord is used to connect the outbound call power supply and the outbound call device on each floor, and the outbound call power supply supplies power to the outbound call device through the power cord. For example, in the embodiment of the present invention, the outbound call power may be provided by the elevator control system. Exemplarily, the outbound call device is the outbound call board. The outbound call device is provided with an up button and a down button. The up button and the down button are respectively provided with up lights and down lights. The outbound call power source is the outbound call device through the power cord. Power supply for up and down lights. When the user calls for the elevator and triggers the up button or down button, the up light or down light is lit.

At least one of the plurality of address lines forms different address line combinations. The outbound call devices on each floor are connected to different address line combinations. The address lines are connected to the outbound call devices. Each address line combination corresponds to a floor address. For example, each address line has a unique code, then different address lines are combined into different code combinations, and the outbound call devices on each floor are connected to different address line combinations. Furthermore, the outbound call devices on each floor correspond to different codes. combination. A unique coding combination is assigned to a floor address in advance. When the elevator is installed and powered on for the first time, the outbound call device determines its floor address based on the connected address line combination, thereby automatically assigning a floor address to the outbound call device on each floor. .

The communication line connects the outside call device and the elevator controller. The elevator controller communicates with the outside call device through the communication line to obtain the floor address of the outside call device. For example, after the outbound calling device determines the floor address where it is located, it sends the floor address to the elevator controller through the communication line, so that the elevator controller can know the floor address where each outbound calling device is located. When a user triggers a call from the outbound calling device on a certain floor, the outbound calling device generates a call request. The call request includes the floor address of the outbound calling device and the calling direction (i.e., up or down). The user's call request is sent through the communication line through the communication line. The call request is sent to the controller. After receiving the call request, the controller controls the elevator to run in the call direction in the call request and accurately stop at the floor corresponding to the floor address in the call request.

In the existing technology, there is a way to control the elevator to run from high to low or from low to high through elevator self-learning. Through the floor height data, the floor address of the outbound call device is automatically allocated. However, during the on-site elevator installation and commissioning stage, not all call devices are installed at once, but more call devices are installed only on some floors. The self-learning method will lead to incorrect floor address allocation. In addition, during the maintenance and use phase of the elevator, when an outbound call device needs to be repaired or changed, the elevator needs to enter the address learning mode and re-learn the configuration through self-learning. The operation is too cumbersome and will also affect the use of the elevator.

The embodiment of the present invention provides an elevator serial communication cable. Since the outbound call device determines the floor address where it is located based on the connected address line combination, even if the outbound call device is installed on only some floors, it can still make outbound calls for this part of the floor. The device is set to the correct floor address. In addition, during the maintenance and use phase of the elevator, when a certain external call device needs to be repaired or replaced, there is no need to enter the address learning mode and re-study by yourself. The floor address can be assigned after the external call device is connected, which does not affect the normal use of the elevator.

The elevator serial communication cable provided by the embodiment of the present invention includes a power line, a communication line and a plurality of address lines. The power cord is used to connect the outbound call power supply and the outbound call device. The outbound call power supply supplies power to the outbound call device through the power cord.

The address lines are connected to the outbound call devices. Each address line combination corresponds to a floor address. Outbound calls The device determines the floor address it is on based on the connected address line combination, thereby allocating a floor address to the outbound calling device on each floor. The communication line connects the outside call device and the elevator controller. The elevator controller communicates with the outside call device through the communication line to obtain the floor address of the outside call device. Since the installer does not need to manually set the floor addresses for the outbound call devices one by one, labor costs are saved. In addition, even if outbound calling devices are installed on only some floors, the correct floor addresses can be set for these outgoing calling devices. When a certain outbound call device needs to be connected, the floor address can be assigned without affecting the normal use of the elevator.
