【正文】 基于 ZigBee 網(wǎng)絡(luò)的智能變電站溫度檢測系統(tǒng)設(shè)計(jì)與實(shí)現(xiàn) 摘 要 針對當(dāng)前變電站常規(guī)測溫手段實(shí)時(shí)性能差、受安裝環(huán)境限制大、無法實(shí)現(xiàn)對封閉設(shè)備等測溫 度 的難題 , 本文提出了 將 ZigBee 組網(wǎng)技術(shù)運(yùn)用于智能變電站測溫 度系統(tǒng)的方案。通過 SHT10 溫度傳感器、 ZigBee 自組網(wǎng)技術(shù)，系統(tǒng)實(shí)現(xiàn)了對變電站刀閘、母線、電纜、變壓器外殼、線路導(dǎo)線等多個(gè)監(jiān)測點(diǎn)溫度的實(shí)時(shí)監(jiān)測 ,使系統(tǒng)運(yùn)行可靠、穩(wěn)定，有效保障變電設(shè)備的正常運(yùn)行。 本方案中使用 SHT10 溫濕度傳感器和 CC2430 無線芯片搭建了一個(gè)基于MsstatePan 協(xié)議棧 的 無線傳感器網(wǎng)絡(luò) 。 該網(wǎng)絡(luò)由一個(gè)協(xié)調(diào)器充當(dāng)中心節(jié)點(diǎn)和若干 終端節(jié)點(diǎn)一起，構(gòu)成一個(gè)星 型網(wǎng)絡(luò)。 終端節(jié)點(diǎn)負(fù)責(zé)將 SHT10 所采集到的信息反饋給協(xié)調(diào)器， 協(xié)調(diào)器負(fù)責(zé) 接收和存儲(chǔ) 終端節(jié)點(diǎn)發(fā)送來的信息，并向終端 節(jié)點(diǎn)發(fā)布網(wǎng)絡(luò)控制信號(hào)， 利用串口通信技術(shù)與上位機(jī)進(jìn)行通信。最后 通過 Labview 編程語言實(shí) 現(xiàn)對采集到的數(shù)據(jù)進(jìn)行顯示與處理，從而有效的起到了對智能變電站的溫 度監(jiān)控。 關(guān)鍵詞： ZigBee SHT10 CC2430 MsstatePan Intelligent Substation Temperature Detection System Design and Implementation Based on The ZigBee Network Abstract Aiming to several shortings of the normal method on temperature measurement in substation, such as the bad timereal function and the limitation of the environment and the infeasibility in airtight equipment, the ZigBee technology is applied to the temperature measurement the SHT10 temperature sensor and ZigBee work technology,on several points such as the substation,bus,cable,breaker transformer shell and line wires,the real time temperature monitoring system can be realized and make the substation equipment reliable and stable working. The SHT10 temperature sensor and CC2430 wireless chip is used to set up a wireless sensor works based on the MsstatePan protocol stack in this work acts as a coordinator and several terminal nodes and together to form a star node is responsible for SHT10 to collect information and feedback to the coordinator, Coordinator is responsible for receiving and storing the information and distributing work control signal to the terminal node and municating with the upper machine using the serial interface munication ,it through the Labview programming language to realize the collected data on display and processing,thus effectively played to the intelligence of the substation of temperature monitoring.
