BACnet应用层状态机在线测试研究

The Study of On-line Testing for BACnet Application Layer TSM

随着BACnet网络技术的应用发展,对BACnet网络设备协议一致性测试的要求也越来越强烈,本文在比较现有的协议一致性测试方法的基础上,给出了基于在线测试的BACnet协议测试方法,研究了BACnet应用层状态机的运行模式,并采用有限状态机模型对BACnet应用层状态机进行了分析,给出了相应的状态机状态判定方法和在线测试的软件结构。

With the development of BACnet technology, the requirements of protocol implement conformance testing become more and more intense. After comparing the methods of protocol implement conformance testing in existence, the paper presents a BACnet protocol test method based on-line. And then, the paper studies the running model of BACnet application layer TSM, and analyses the TSM using finite state machine model. Finally, this paper presents an algorithm to identify the state of TSM, and describes the software framework of On-line testing.
