遠程供水測控終端系統(tǒng)的設計:介紹了一種新型的鐵路沿線供水遠程測控系統(tǒng)設計方案,可以對供水站點設備進行遠程監(jiān)測,同時還可對設備進行控制。詳細設計了遠程測控終端系統(tǒng)的硬件電路和軟件。系統(tǒng)由監(jiān)控中心(上位PC 機) 和分布在供水現(xiàn)場的下位機單片機系統(tǒng)組成。兩部分之間通過RS485/ 以太網(wǎng)轉(zhuǎn)換模塊經(jīng)以太網(wǎng)進行通信。充分體現(xiàn)該系統(tǒng)設計的靈活性和可擴展性。其實際應用結(jié)果表明:該系統(tǒng)可靠性高,運行穩(wěn)定,具有很強的實用推廣價值。
關鍵詞:遠程測控終端;供水;RS485 ;以太網(wǎng)

Abstract :A kind of new remote measuring and controlling terminal system for the water supply of railway station is introduced. It can monitor the equipments of the remote station , and also can control these equipments’operation. Its hardware configuration , circuit
construction and software designing ware provided in detail. This systemwas composed of the supervision center (PC) and the remote station’sMCU system , which are lined by RS485/ Ethernet converter through Ethernet. The flexibility and expandability of the system was achieved. Its running results show that it is reliable and steady. So it is worthwhile for further practical application.
Key Words :remote measuring and controlling terminal ;water supply ;RS485 ;ethernet
