系統(tǒng)主要由監(jiān)控中心、無線通信系統(tǒng)、現(xiàn)場監(jiān)控終端、傳感器及儀表四部分組成。

監(jiān)控中心：由微機、無線數(shù)傳機、全向天線、模擬屏及UPS組成，主要完成各現(xiàn)場終端數(shù)據(jù)的實時采集、監(jiān)測、控制、數(shù)據(jù)存儲、打印報表、數(shù)據(jù)查詢等功能。

無線通信系統(tǒng)：監(jiān)控中心與各泵站終端之間采用無線方式通訊。監(jiān)控中心為主動站，其它終端副站為被動從站，該系統(tǒng)采用無線電管理委員會給定的數(shù)據(jù)頻率，以一點對多點的方式與從站通訊，監(jiān)控中心為全向天線，各副站為定向天線。

現(xiàn)場監(jiān)控終端：核心為PLC，是一個智能設備，它有自己的CPU和控制軟件，主要完成現(xiàn)場的數(shù)據(jù)采集、轉(zhuǎn)換、存儲、報警、控制等功能，并通過無線信道與監(jiān)控中心微機進行數(shù)據(jù)通信。根據(jù)監(jiān)控中心的命令分別完成系統(tǒng)自檢、數(shù)據(jù)傳送、控制輸出等任務。

傳感器及儀表：是PLC監(jiān)測現(xiàn)場信號的“眼睛”，現(xiàn)場所有信號都需經(jīng)過傳感器及儀表的轉(zhuǎn)換，才能輸出標準信號，被PLC終端所接受。系統(tǒng)主要測量電壓、電流、液位、壓力、流量及耗電量等參數(shù)。

現(xiàn)場PLC監(jiān)控終端是工業(yè)現(xiàn)場與監(jiān)控中心之間的橋梁紐帶，一方面它采集現(xiàn)場儀表、變送器、設備運行狀態(tài)等信號，另一方面它又與監(jiān)控中心通訊，執(zhí)行有關(guān)命令。現(xiàn)場終端一般無人值守。因此，終端機的性能和質(zhì)量對系統(tǒng)的可靠性影響很大。經(jīng)充分論證，選用西門子S7-200系列PLC作現(xiàn)場終端具有較高的性能價格比，它具有體積小、易擴展、性能優(yōu)等特點，非常適合小規(guī)模的現(xiàn)場監(jiān)控。New Redington 1-PCU-34 Mechanical Counter 4 Digit Right Hand Actuation
