| Abstract: | Owing to the fact that the communication protocol of the digital electric-hydraulic governor is not in accord with that of the monitoring and control system, this paper proposes a method that realizes communication between the PLC-based governor and the monitoring and control system by protocol conversion programming with C language, and introduces in detail the principle of protocol conversion, the hardware structure of the communication system and the realization of software. It is proved that this method has the advantages of high reliability, high efficiency and low cost by way of strict local operational experiment. |
