Problems solved by technology

These connections have designated connection positions, and if they are connected incorrectly, they will not work normally or even be damaged.
[0006] b) Data lines generally have requirements, such as shielded wires, twisted-pair wires or shielded twisted-pair wires must be used, the length of wiring and grounding methods are also required, otherwise the reliability of communication will be affected

Embodiment Construction

[0021] refer to figure 1 , figure 2 , a communication system for elevator calls of the present invention, comprising a main station and sub-stations, the main station is located in the main control cabinet of the elevator, and the sub-stations are divided into external call sub-stations located on each floor outside the elevator hall door and sub-stations located in the elevator There is one internal call substation in the car, one external call substation on each floor, and only one internal call substation. The modulation and mediation of communication data between the main station and the substations uses a low-speed baud rate of 200-600HZ. Power carrier communication technology.

[0022] refer to figure 2 , the circuits of the master station and the substation are composed of a power supply circuit, a power carrier modulation and mediation circuit and a CPU for processing communication protocols.

[0023] Further, as a preferred embodiment, the main station and the su...

Abstract

The invention discloses a communication system for the call system of an elevator, comprising a main station and a substation; the main station is arranged in the main control cabinet of the elevator; the substation is divided into external calling substations arranged on each floor and an internal calling substation arranged in the elevator car; the modulation and demodulation of the communication data between the main station and the substation are realized through the low-speed power carrier communication technique with the baud rate of 200 Hz to 600 Hz. Because the communication data between the main station and the substation in the system adopt the low-speed power carrier communication technique with the baud rate of 200 Hz to 600 Hz, the communication system has the advantages of good anti-interference performance, long communication distance and low cost.

Description

technical field [0001] The invention relates to an elevator calling device, in particular to an elevator calling communication system realized by using power carrier communication. Background technique [0002] (1) There are currently two methods of elevator landing calls: direct connection and communication connection. Direct connection refers to wiring each call button and indicator light directly to the electric cabinet in the equipment room. The communication connection is installed on each floor station or includes a function board in the car, and the call button and indicator light are connected to the function board there, and each function board and the electric cabinet in the machine room use communication technology to exchange signals. The invention belongs to the technology of communication connection. [0003] (2) The direct connection method is simple in technology and good in reliability. However, the cables used and the connection points of the control cab...
