Description

Cable architecture for respectively connecting layer door lock and calling box Technical Field The invention relates to the technical field of elevators, in particular to a cable framework for respectively connecting a layer door lock and a calling box. Background In elevator systems, the connection of landing door locks and call boxes to the control cabinet is of paramount importance. At present, a common connection mode adopts a branch cable. The connection mode is characterized in that a bifurcation point is arranged between every two layers of the cable so as to facilitate signal transmission and cable management (refer to figure 1 of the attached drawing). The divergence cable is disposed within the elevator hoistway, and thus, in order to protect the divergence point from the external environment, an external material such as a heat shrink, a junction box, or a PVC jacket is generally used for protection. Specifically, the communication signals of the landing door lock and the power supply and communication of the calling box are firstly transmitted to each bifurcation point in the elevator hoistway from the control cabinet through the main cable of the bifurcation cable. And in the branching point, the layer door branch cable and the calling box branch cable are respectively connected with a branching main cable in a signal mode. After the connection is completed, a landing door lock branch cable and a calling box branch cable are led out from the branching points to the installation positions of the landing door lock and the calling box respectively, and then are connected with the landing door lock and the calling box. The method has the advantages that the layer door lock cable, the calling box power supply and the communication cable routing path are redundant and repeated, the routing distance is long, the cable material cost is high, a bifurcation point is arranged between every two layers in the bifurcation cable, the branch cable from the bifurcation point to the layer door lock and the calling box also has the problem of redundant and repeated routing path and turn-back of the routing path, the cable material cost is high, the layer door lock loop adopts a serial connection mode, the layer door lock loop has larger loop resistance, the cable resistance of the layer door lock loop can be increased under the condition that the elevator height is larger, the power supply design of the layer door lock loop and the effective conduction of the layer door lock loop are not utilized, the bifurcation point is arranged in an elevator hoistway, fixed material cost is generated, the main branch cable, the layer door lock branch cable and the calling box branch cable are required to be connected in the bifurcation point, the processing labor steps are multiple, the mode of the bifurcation cable and the calling box branch cable is provided with independent ground wires, and the redundancy exists in the condition that the main cable, the layer door lock and the branch cable of each section is provided with independent ground wires, and the redundancy exists in the condition of the redundancy However, the layer door lock signal and the calling box are mutually independent and do not interfere with each other, but the current two are bound on the branching cable to arrange the wiring, so the wiring of the layer door lock signal is also limited by the number of connectable stations of the calling box communication terminal, each 16 layers is required to be set as a design interval, and each design interval is required to return to the control cabinet for connection. This approach not only increases the length and complexity of the cable, but may also affect the stability and transmission efficiency of the signal.
