Virtual Serial Port in the Construction of the CAN-Bus Network Technology Research

Abstract:

This paper Introduces a simple and reliable method to connect an ordinary twisted pair RS-232 up to 2048 devices and transmit the communication data more than 10 kilometers by using ZLGCAN interface card, CAN232MB converters and other equipment. The virtual serial port server makes use of CAN-bus network for data communications, guaranteeing the reliability of communic-ation, improving the RS-232 transmission distance, and simplifying the wiring process. Meanwhile user’s operation of the virtual serial port and a standard PC are compatible with the basic serial port operation. However, if there is a large number of continuous transmission of data to the case, the ac-tual serial data transfer rates is determined by the number of virtual serial port.
