Design of Specification for Data Communication Interface in Bus Rapid Transit (BRT) Intelligent System

摘要

Formulating the specification for data communication interface in Bus Rapid Transit (BRT) benefits the rapid and healthy development of BRT intelligent system. There are many communication standards adopted in the BRT intelligent system in China and abroad, but less of them correspond to specify its practice application. With the aim to facilitate its rapid and healthy development, the framework for data communication interface in BRT based on practice is proposed. This paper presents a constituent content of the hierarchical model which integrates each specification of the communication protocols that combine with key technology and merits. Whereas the specification discussed has been utilized in many engineering practices, and has made a big difference in solving practical problems.
