【摘要】：溫度是反映變電站電力設(shè)備狀態(tài)的重要方面。監(jiān)測(cè)變電設(shè)備溫度主要是為了記錄設(shè)備在運(yùn)行狀態(tài)下的實(shí)時(shí)溫度,減少安全事故的發(fā)生,進(jìn)而減少對(duì)電力系統(tǒng)穩(wěn)定運(yùn)行的影響。目前絕大多數(shù)變電站點(diǎn)采用的是巡視測(cè)溫的方式,需要值班員人工測(cè)溫,如果設(shè)備發(fā)熱處要求的測(cè)溫頻次很高,值班員需要多次手持紅外熱像儀靠近開(kāi)關(guān)柜去測(cè)量設(shè)備表面溫度,這極大增加了值班員的工作量,也增加了發(fā)生安全事故的可能性,而且人工巡檢的溫度監(jiān)測(cè)精確性差,連續(xù)性不高,可能導(dǎo)致異常運(yùn)行條件下電力設(shè)備的故障發(fā)生。針對(duì)上述問(wèn)題,本文設(shè)計(jì)了一種變電站設(shè)備無(wú)線溫度監(jiān)測(cè)系統(tǒng),該系統(tǒng)可以實(shí)現(xiàn)電力設(shè)備溫度的在線監(jiān)測(cè),通過(guò)設(shè)定不同地點(diǎn)的報(bào)警溫度值,實(shí)現(xiàn)對(duì)多點(diǎn)的溫度采集、分析和報(bào)警。根據(jù)系統(tǒng)所要實(shí)現(xiàn)的功能和技術(shù)要求,系統(tǒng)設(shè)計(jì)結(jié)構(gòu)分為采集層、傳輸層和應(yīng)用層。采集層中采用了帶ZigBee通信模塊的CC2530采集節(jié)點(diǎn),通過(guò)DS18B20溫度傳感器實(shí)時(shí)采集現(xiàn)場(chǎng)電力設(shè)備溫度信息,以無(wú)線方式發(fā)送給傳輸節(jié)點(diǎn)。傳輸層中采用了以ARM9為核心的S3C2440傳輸節(jié)點(diǎn),它作為其下溫度采集節(jié)點(diǎn)組成的ZigBee網(wǎng)絡(luò)的網(wǎng)關(guān),向下管理和接收采集節(jié)點(diǎn)的溫度信息,向上通過(guò)以太網(wǎng)與遠(yuǎn)端監(jiān)控中心進(jìn)行通信。遠(yuǎn)端監(jiān)控中心使用MySQL數(shù)據(jù)庫(kù)管理體系的數(shù)據(jù)庫(kù),存放采集節(jié)點(diǎn)信息、傳輸節(jié)點(diǎn)信息、電力設(shè)備信息等,同時(shí)可以設(shè)定多點(diǎn)的報(bào)警閾值。監(jiān)控界面的編寫使用的是java web開(kāi)發(fā)環(huán)境Eclipse,通過(guò)配置Tomcat的環(huán)境變量、JDK的開(kāi)發(fā)環(huán)境變量,使用javaBean、javaScript以及HTML作為工具,將MySQL更新的數(shù)據(jù)導(dǎo)入到網(wǎng)頁(yè)上顯示。文中給出了采集節(jié)點(diǎn)、傳輸節(jié)點(diǎn)的硬件電路和軟件實(shí)現(xiàn)方案。分析了遠(yuǎn)端監(jiān)控中心數(shù)據(jù)庫(kù)的訪問(wèn)過(guò)程,構(gòu)建了 MySQL數(shù)據(jù)庫(kù),設(shè)計(jì)了瀏覽訪問(wèn)界面。最后,對(duì)數(shù)據(jù)庫(kù)的運(yùn)行和訪問(wèn)界面進(jìn)行了測(cè)試,結(jié)果表明可以實(shí)現(xiàn)溫度的存儲(chǔ)、顯示和查詢。最后,本文對(duì)研究工作完成了總結(jié),還針對(duì)移動(dòng)終端APP監(jiān)測(cè)軟件的開(kāi)發(fā)和以及實(shí)現(xiàn)溫度的預(yù)警功能進(jìn)行了展望。
[Abstract]:Temperature is an important aspect to reflect the state of substation power equipment. The main purpose of monitoring the temperature of substation equipment is to record the real-time temperature of the equipment under the operation state, to reduce the occurrence of safety accidents, and then to reduce the influence on the stable operation of power system. At present, most substation sites use the method of inspecting temperature, which requires manual temperature measurement by duty personnel. If the temperature measurement frequency required by the heating place of the equipment is very high, Duty attendants need to hold infrared thermal imagers several times to measure the surface temperature of the equipment near the switchgear, which greatly increases the workload of duty guards and the possibility of safety accidents. Moreover, the temperature monitoring accuracy of manual inspection is poor. The continuity is not high, which may lead to the fault of power equipment under abnormal operation conditions. In order to solve the above problems, this paper designs a wireless temperature monitoring system for substation equipment. The system can realize the on-line monitoring of power equipment temperature. By setting the alarm temperature value of different locations, the temperature collection of multiple points can be realized. Analysis and alarm. According to the functions and technical requirements of the system, the system design structure is divided into collection layer, transmission layer and application layer. CC2530 acquisition node with ZigBee communication module is used in the collection layer. The temperature information of field power equipment is collected in real time by DS18B20 temperature sensor and sent to transmission node by wireless mode. In the transport layer, S3C2440 transmission node, which is based on ARM9, is used as the gateway of ZigBee network composed of temperature acquisition nodes. It manages and receives the temperature information of the collection nodes down and communicates with the remote monitoring center through Ethernet. The remote monitoring center uses MySQL database management system to store node information, transmit node information, power equipment information, etc. At the same time, multi-point alarm threshold can be set. Monitoring interface is written using java web development environment Eclipse, by configuring Tomcat environment variables of JDK development environment variables, using javaBeaner javaScript and HTML as tools, the java web updated data will be imported to the web page to display. In this paper, the hardware circuit and software implementation of acquisition node and transmission node are given. The accessing process of remote monitoring center database is analyzed, MySQL database is constructed and browsing interface is designed. Finally, the running and accessing interface of the database are tested, and the results show that the temperature storage, display and query can be realized. Finally, the research work is summarized, and the development of mobile terminal app monitoring software and the realization of temperature warning function are prospected.
