Embodiment Construction

[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further elaborated below.

[0015] see figure 1 The shown elevator cable that satisfies the RS485 / 232 communication function includes a flat outer sheath 1000 and a cable core arranged in the middle of the flat outer sheath 1000. In this embodiment, the cable core includes The video line 100, two sets of control lines 200 respectively arranged on both sides of the video line 100 and four sets of power lines 300 respectively set outside the two sets of control lines 200, in order to enhance the bending resistance of the cable, the four sets of power lines 300 A reinforcement rope 400 is provided on the outer side of the body.

[0016] The RS485 communication cable 500a and the RS232 communication cable 500b are respectively arranged on the inner and outer sides of the flat outer sheath 1000, the RS485 communi...

Abstract

The invention discloses an elevator cable satisfying an RS485 / 232 communication function. The elevator cable comprises a flat outer sheath and a cable core disposed in the middle of the flat outer sheath. An RS485 communication cable and an RS232 communication cable are respectively disposed on two sides of the cable core. Each of the RS485 communication cable and the RS232 communication cable is a double-stranded communication cable. The stranding directions of the RS485 communication cable and the RS232 communication cable are opposite. A first shielding layer is disposed in the RS485 communication cable. A second shielding layer is disposed in the RS232 communication cable. The elevator cable has the advantages that the cable number in a shaft is reduced, and normal operation of an elevator is guaranteed; in addition, the stranding directions of the RS485 communication cable and the RS232 communication cable are opposite, so that the bending resistance of the elevator cable can be guaranteed, signal interference between the RS485 communication cable and the RS232 communication cable and the cable core can be prevented by the shielding layers, and normal communication can be guaranteed.

Description

technical field [0001] The invention relates to the field of elevator cables, in particular to an elevator cable meeting the RS485 / 232 communication function. Background technique [0002] With the development of society, elevators have gradually become an indispensable tool for people's production and life. When elevators are used, they move up and down continuously. At the same time, elevators need to have corresponding communication and monitoring equipment. Generally, the RS485 or RS232 communication cables of the elevator are arranged in parallel with the elevator cables and bound together by cable ties. However, this wiring method has the following disadvantages: 1. The number of cables in the hoistway is too large, which affects the normal operation of the elevator; 2. RS485 or RS232 communication cables and elevator cables are easy to interfere with each other, affecting the transmission of signals. Contents of the invention [0003] The object of the present inve...
