摘 要
設(shè)計以凌陽單片機SPCE0601A為核心，并配以適當?shù)耐鈬酒c接口電路實現(xiàn)變壓器的溫度監(jiān)控。系統(tǒng)采用多組風機對油浸風冷式變壓器降溫，變壓器油溫由預(yù)埋在變壓器油中的鉑電阻采集，將采集到的油溫在就地和遠端實時顯示，溫度的顯示由LED數(shù)碼管實現(xiàn)。當控制變壓器的油溫大于上限溫度值時，投入全部風機；當油溫低于下限溫度值時，停止全部風機的運行；變壓器的油溫介于上限值和下限值之間時,風機按工藝要求運行。可編程RF無線收發(fā)器芯片CC1000實現(xiàn)主從機之間的數(shù)據(jù)傳輸，使中心控制室及時掌握變壓器風機的運行狀況，實現(xiàn)遠程溫度監(jiān)控。風機出現(xiàn)故障時，相應(yīng)的發(fā)光二極管點亮,并且報警電路發(fā)出報警信號。系統(tǒng)要具備完善的過壓、過載、缺相檢測和保護功能。

Abstract
This design is based on the Sunplus MCU SPCE0601A , and go together with the appropriate outer circle chip and interface electric circuit to carry out supervise and control oil temperature transformer on the spot and at the long-distance .This system adopts several group electromotor to cool down the temperature of the transformer.The temperature is collected by the temperature transducer of the platinum resistance , The temperature that is gathered will display at right on the spot and at the long-distance . the manifestation of the temperature is realized by the LED figures tube. When the oil temperature of the control transformer is bigger than the upper limit temperature enactmented , throw in all several group electromotor to run ;But when the oil temperature is low in the least temperature value, stop all movements of several group electromotor .When system circulated normally, each three sets of autos threw in movement by turn in six sets of the six group electromotor .The programmable RF wireless transceiver chip CC1000 carries out a lord to deliver from the data between the main single chip and contronl room , making the center control room master the condition of the transformer in time, carrying out supervise and control of the long-distance . when the wind motor appeared to break down ,LED gave out light , and give out alarm. Meanwhile, protection circuit(including voltage, over loading, lacking electrical wire) has been designed for system.
