Abstract
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 ...

Embodiment Construction
[0029] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0030] see figure 2 , a multi-serial port data transmission method includes the following modules:
[0031] Serial port configuration management module, which is used to configure serial port parameter data, said parameter data includes baud rate, data bit, parity bit, stop bit, flow control; after the serial port configuration is completed, a configuration file is generated, and the configuration file can be edited Load, save and modify operations;
[0032] Data receiving and reading module, which is used to receive and read the serial port data sent by the peripheral serial device;
[0033] Serial port data forwarding module, which is used to forward the received peripheral serial device data to the designated lower computer device;
[0034] Data storage management module, which can store the received peripheral serial device data in the form of da...
