| Abstract: | To achieve the real-time detection of water level in industry production process, a distributed control system of PC and multi-supersonic water level instrument is designed. It uses RS485 communication interface to design hardware structure, upper and lower computer communication program. Based on the debug with one upper and three lower instruments, it is verified that the communication system is stable. |
