As the language for communication, the protocol plays the role of bridge between traffic monitor systems and traffic guidance displays. This paper introduces the communication protocol, JJ-KXB-Protocol, specially developed for traffic guidance displays on the basis of MODBUS. The protocol structure and the frame types are presented. The design of the table of displa- ying data is described in detail. Some key technologies used in the hardware platform to support JJ-KXB-PROTCOL are ana- lyzed.
