介绍了河海大学水利电力工程学院水轮机控制试验室的布置、设备和功能。从计算机通信的基本原理出发,结合试验室对试验结果要求准确可靠,并要为以后改进留有充分余地的实际需求,设计了一套基于 TCP/IP 协议的通信系统。由于命令传送过程中不允许发生误传命令,而在数据传送过程中则要求数据准确,因此该系统将命令与数据分开处理,并规定了其详细的帧格式。
The layout, equipment and functions of hydraulic turbine control laboratory of Hohai University are introduced. Based on the basic principle of computer communication, the test system based on TCP / IP protocol is designed based on the accurate and reliable test results required by the laboratory and the practical requirements of leaving room for future improvement. Since commands are not allowed to be misdirected in the transfer process, they are required to be accurate during data transfer. Therefore, the system processes the commands separately from the data and specifies the detailed frame format.
