Title:
RS232-BASED COMMUNICATION PROTOCOL
Document Type and Number:
WIPO Patent Application WO/2022/160779
Kind Code:
A1
Abstract:
Disclosed in the present invention is an RS232-based communication protocol, comprising a link layer protocol and an application layer protocol. The Baud rate of an RS232 link layer is set to be 57600 or 115200, and eight data bits, one stop bit, and no parity bits are set. A communication packet of an RS232 application layer comprises a start frame 1, a start frame 2, a command word, a source address, a data domain, a priority, and a checksum. According to the RS232-based communication protocol, a control instruction protocol of a first network terminal to a second network terminal is implemented by expanding the content of the protocol. According to the RS232-based communication protocol, a response protocol of the second network terminal to a control instruction of the first network terminal is implemented by expanding the content of the protocol. According to the present invention, an application layer communication protocol having good flexibility, high data transmission efficiency, and good robustness is implemented. On the basis of the communication protocol, the protocol content can be expanded according to actual requirements. Upon verification of actual products, the present communication protocol has excellent universality and stability.
