Abstract

The embodiment of the invention discloses a multi-serial-port communication control method and device and an upper computer. The method comprises the steps that a plurality of serial port control areas of a human-computer interaction interface of an upper computer are monitored, control information input into at least one serial port control area is obtained, the control information at least comprises serial port information and to-be-transmitted information, and one serial port control area is used for controlling one serial port; and the to-be-transmitted information is transmitted to a lower computer through a target serial port indicated by the serial port information. Communication control over a plurality of serial ports is achieved through a single human-computer interaction interface, the purpose of simplifying serial port operation is achieved, and the accuracy of serial port control can be improved.

Description

technical field [0001] The invention relates to the technical field of industrial automation, in particular to a multi-serial port communication control method, system and upper computer. Background technique [0002] With the development of computer technology and communication technology, traditional industrial control transitions to automatic control. In industrial automation control, the host computer and industrial equipment are connected through a serial port to control the industrial equipment to perform corresponding information collection, program upgrade, equipment debugging and other operations. The upper computer can set multiple serial ports at the same time, and perform serial port parameter configuration and serial port communication control through the upper computer control software. [0003] Among them, the host computer control software only supports one serial port control. If you want to control multiple serial port communications, the two common contr...
