Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] like Figure 1 As shown, the 4-wire bus connection method is used on the basis of the traditional universal asynchronous transceiver transmitter, and the conversion circuit is added to the hardware to realize the single-bus synchronous real-time communication. The single-bus (1-wire) means only one data line is used. For data exchange and control, a device (master or slave) is connected to the data line through an open-drain or tri-state port to allow t...

Abstract

The invention discloses a method for realizing single-line communication of elevator bus buttons. The method comprises the following steps of: realizing single-bus synchronous real-time communicationby adding a same-in and same-out multiplexing mechanism on software and hardware on the basis of a traditional universal asynchronous transceiving transmitter in a four-line bus connection mode, in asingle-bus link circuit, all equipment are connected in parallel, a host on the software provides synchronization signals for time synchronization between master equipment and slave equipment, data reading and writing are carried out in a TDM (Time Division Multiplexing) transmission mode, and after the method is adopted, the real-time performance of communication is improved, line links are reduced, maintenance is reduced, and the reliability of electrical links of the equipment is improved.

Description

Technical field: [0001] The invention relates to the field of elevator control, in particular to a method for realizing single-line communication of elevator bus buttons. Background technique: [0002] At present, there are generally a pair of signal wires and three power wires in the elevator bus button, and there are heavy communication loads during answering, transmission, and query, the speed of communication collection is slow, there are many communication lines, and the real-time performance is low. Invention content: [0003] The present invention aims to solve the defects of the existing elevator bus button communication, increase communication reliability, reduce line links, and speed up the collection speed of the elevator, and proposes a method for realizing single-line communication of the elevator bus button. [0004] Technical solutions of the present invention are as follows: [0005] A method for realizing the single-line communication of elevator bus butt...
