Automatic connection system of multiple machine station and method

Abstract

The invention relates to a connection system and a method that automatically sets a communication protocol and a table number among a plurality of consoles. one console is selected from a plurality of consoles to be set as a master console, the rest are set to slave consoles, wherein, each console is provided with a series connection input end, a series connection output end and a master-slave communication end. The series connection output ends of all slave consoles are respectively connected with the series connected input ends of all slave consoles at the next level, thereby forming series connection, while the master-slave communication ends of all consoles are in parallel connection. When the last-level master console sends a group of data on the communication protocol to the slave console through a master-slave communication console, each slave consoles sets a communication protocol, and a first slave console produces the data that the serial number is 1, and sends the information of the number to the next level slave console, the next level slave console pluses 1 to the serial number data sent by the former, and delivers downward to the slave console of every level in turn and carries out the treatment of increasing 1, finally sends to the master console, thus the master console gets the total number of the slave console to specify the number of the slave consoles.

Description

technical field [0001] The invention relates to a connection between multiple machines, in particular to a machine connection system and method for automatically setting communication protocols and machine numbers. Background technique [0002] In the field of automatic control, it is often necessary to use multiple machines to form a distributed control system, but the machines of the distributed control system still need to be connected and communicated, so that the entire control system can fully coordinate and operate. [0003] The known connection of multiple machines generally adopts a master-slave structure as shown in Figure 1. The machines are connected through communication lines, and the slave machines are controlled by the master machine to operate. For communication, it is necessary to adopt a consistent communication protocol (protocol), such as communication rate (baud rate), encoding format, and odd / even parity check, etc., and each machine must also be set w...

AI Technical Summary

Problems solved by technology

However, the machine cannot automatically set a unified communication protocol and different machine numbers, and the staff must set each machine separately, so the staff must run back and forth between the machines to repeatedly perform the same , which is quite cumbersome and inefficient

In addition, manually setting such detailed and complicated data is also very likely to cause setting errors. As long as there is any wrong data setting, it will affect the operation of the entire control system
