摘要 I 摘 要 電力操作電源監(jiān)控是電力系統(tǒng)的重要設(shè)備,其性能和質(zhì)量直接關(guān)系到電網(wǎng)的穩(wěn)定運(yùn)行和設(shè)備安全。隨著計(jì)算機(jī)技術(shù)的高速發(fā)展,能否有效地對(duì)電力操作電源中的電壓模塊及電池的溫度進(jìn)行監(jiān)視對(duì)電力網(wǎng)的綜合效率和可靠性,滿足電站自動(dòng)化的需求,具有非常重要作用。 本設(shè)計(jì)就 電力操作電源的直流電流、直流電壓、電池溫度和三相交流電壓進(jìn)行了處理并通過(guò)單片機(jī)采集,最終實(shí)現(xiàn)當(dāng)采集的數(shù)據(jù)出現(xiàn)問(wèn)題時(shí),單片機(jī)提示報(bào)警并有益于更好的監(jiān)控。 硬件部分主要 AT89C51 作為集中監(jiān)控器,采用 AD0809 對(duì)電壓進(jìn)行采集 并檢測(cè),采用 18b20 溫度傳感器 測(cè)電池溫度,通過(guò) LM4229LCD240128 液晶顯示,當(dāng)溫度及各路電壓出現(xiàn)異常情況時(shí),聲光電路報(bào)警,并在液晶相應(yīng)位置 了 出現(xiàn)提示,通過(guò)編程實(shí)現(xiàn)對(duì)整個(gè)系統(tǒng)的控制。 關(guān)鍵詞: 電力操作電源 AD0809 LCD240128 液晶Abstract II Abstract Operation of the power supply monitoring is an important equipment of power system, its performance and quality directly related to the stable operation of power work and equipment safety. With the rapid development of puter technology, the effectiveness of the electric operating power supply voltage module and battery temperature monitoring on power work prehensive efficiency and reliability, to meet the demand of power station automation, has a very important role. The design of power supply operation of the DC current, DC voltage, battery temperature and threephase AC voltage is processed through the SCM acquisition, final implementation when collecting data when problems arise, MCU alarm and is beneficial to the better monitoring. The hardware part of the main AT89C51 as centralized monitor, using AD0809voltage acquisition and detection,18B20 temperature sensor with sensing battery temperature, through the LM4229LCD240128liquid crystal display, when the temperature and various voltage abnormality, an acoustooptic alarm circuit, and liquid crystal corresponding position prompted, programmed to realize the control of the entire system.
