Multi-serial-port data transmission method and transmission center system

Abstract

The invention relates to a multi-serial-port data transmission method and a transmission center system. The system comprises a serial port configuration management module, a data receiving and reading module, a serial port data forwarding module, a data storage management module and a data capturing and processing module, wherein the serial port configuration management module is used for configuring serial port parameters of a serial port server, generating a configuration file, and loading, storing and modifying the configuration file; the data receiving and reading module is used for receiving and reading serial port data transmitted by peripheral serial port equipment; the serial port data forwarding module is used for forwarding received peripheral serial port equipment data to specified lower computer equipment; the data storage management module is used for storing received peripheral serial port equipment data in the form of a database or a local text file; and the data capturing and processing module is used for capturing received peripheral serial port equipment data and performing addition, subtraction, multiplication, division and power operation on a captured data segment. The method is applied to the transmission center system. The method and the system have the beneficial effects that the quantity of physical connection links of serial port data can be reduced.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a multi-serial port data transmission method and a transmission center system. Background technique [0002] The serial port is a commonly used data interface in the fields of industrial control, aerospace, aviation and ships. It is different from the network interface. In order to realize the communication between multiple serial ports, the traditional method is to use point-to-point network transmission mode, that is, any two serial ports for communication Both establish a physical link connection. This method has the following disadvantages: 1) Any serial port communication needs to be connected, resulting in a large amount of redundancy in the line, and N nodes need (for example, 4 nodes need 6 links); 2) The interface configuration between the two serial ports must be completely consistent, for example, the two connected serial ports must be RS485 interfaces, and the baud ...

This method has the following disadvantages: 1) Any serial port communication needs to be connected, resulting in a large amount of redundancy in the line, and N nodes need (for example, 4 nodes need 6 links); 2) The interface configuration between the two serial ports must be completely consistent, for example, the two connected serial ports must be RS485 interfaces, and the baud rate must be They are exactly the same. If they are different, a serial port adapter must be used for conversion and connection, which causes great inconvenience in project implementation; 3) The data cannot be centrally controlled. If the transmission path needs to be changed at any time, the data needs to be properly adjusted. Recognition, calculation and storage, etc.
