摘  要
本文在對煤礦井下變電所高壓供電現狀及國內外相關產品概況分析的基礎上，研制了一套井下供配電安全監控系統。選用單片機AT89C52用以控制波特率的選擇，增強了通信接口的通用性。智能采集器獨立于原綜合保護裝置，由單片機控制，增加電壓傳感器、電流傳感器、數據處理軟件等，實時采集高壓配電開關所帶負載的電壓、電流、環境溫度、真空開關的開合狀態等參數。為了縮短地面計算機依次巡測所有智能采集器的時間，設計了雙單片機結構的變電所分站，變電所分站在計算機和智能采集器之間，用一片雙口RAM進行數據暫存和緩沖，可以實現雙向通信，在整個系統結構中起著承上啟下的作用，從而提高系統的整體性能。論文在進行上述硬件設計的同時，還設計了一套計算機多功能軟件，主要包括串行通信程序和數據庫，以及相關程序的編寫，對煤礦生產有著相當重要的意義。

Abstract
This article to the coal mine shaft transformer substation high-voltage power supply present situation and in the domestic and foreign related product survey analysis's foundation, developed set of mine shafts to supply the power distribution  safe supervisory system. In order to realize computer's long-distance range monitoring, designed the correspondence connection to complete the signal transformation, monolithic integrated circuit AT89C52 uses to control the baudrate the choice, strengthened the correspondence connection versatility. The intelligent gathering independence in the original synthesis protective device, the electric current sensor, the data processing software and so on, the real-time gathering high pressure power distribution switch brings the load voltage, the electric current, the ambient temperature, the vacuum switch to open and close parameters and so on condition, simultaneously carries out the ground-based computer to send in “switches on ', “minute floodgate”, “replacement” and so on control operations. In order to reduce the ground-based computer to patrol in turn measured that all intelligent gathering time, has designed the double monolithic integrated circuit structure transformer substation substation, the transformer substation substation in the computer and between intelligent gathering, carries on the data interim and the cushion with piece of pair of mouth RAM, may realize the two-way communication, is playing the role which in the overall system structure links the preceding with the following, The paper while carries on the above hardware design, but has designed set of computer multi-purpose softwares, mainly includes the serial communication procedure and the database.
