【摘要】：配網(wǎng)管理終端作為配電系統(tǒng)的執(zhí)行單元,連接著配電主站和配電一次設(shè)備,它的實時性、可靠性、精度等直接影響著配電系統(tǒng)的安全和可靠運行。過去,國內(nèi)外大多生產(chǎn)廠商采用人工手動方式對配網(wǎng)管理終端進行出廠前的校準、功能測試,這種方式步驟復(fù)雜,可靠性和效率低下,不適用大規(guī)模批量生產(chǎn)。針對上述問題,本文研發(fā)一種通用型配網(wǎng)管理終端自動調(diào)試及檢驗系統(tǒng),根據(jù)不同類型的終端靈活配置測試與校準要求,實現(xiàn)高效、高質(zhì)量的生產(chǎn)。首先,系統(tǒng)功能主要包括數(shù)據(jù)校準和功能測試兩個方面,其中,功能測試主要包括對配網(wǎng)管理終端的模擬量采集測試、開關(guān)量采集功能測試、出口繼電器動作測試等。整個測試過程由后臺軟件控制,嚴格遵循前后邏輯順序完成測試過程,并自動生成測試報告及語音提示測試完成或者異常。其次,根據(jù)系統(tǒng)的總體設(shè)計方案,完成了硬件與測試控制系統(tǒng)的設(shè)計。系統(tǒng)的硬件設(shè)計主要為智能I/O模塊,以ARM為核心處理器,包括電源模塊電路、E2PROM拓展電路、RS485電路、開關(guān)量輸入電路以及繼電器輸出電路,通過以太網(wǎng)與RS485通信接口,以IEC-104、Modbus_RTU協(xié)議實現(xiàn)與測試控制系統(tǒng)的通信。測試控制系統(tǒng)通過Java平臺,采用多任務(wù)機制開發(fā),包括測試列表模塊和人機界面。其中,測試任務(wù)采用XML標記語言描述,實現(xiàn)測試任務(wù)標準化存儲及讀取,人機界面則利用Java Swing開發(fā)包在Netbeans的開發(fā)環(huán)境下構(gòu)建,實現(xiàn)測試的控制與監(jiān)視。最后,通過對不同種類的配網(wǎng)管理終端進行測試與校準,驗證了系統(tǒng)的可行性。實驗證明了系統(tǒng)對各個功能的故障識別達到了100%,且符合配電行業(yè)對配網(wǎng)管理終端的測試與校準精度要求,成功應(yīng)用于企業(yè)內(nèi)部終端的生產(chǎn)過程中,對終端自動測試與檢驗具有實際應(yīng)用價值。
[Abstract]:As the executive unit of the distribution system, the distribution network management terminal is connected to the distribution main station and the distribution primary equipment. Its real-time, reliability and precision directly affect the safe and reliable operation of the distribution system. In the past, most manufacturers at home and abroad used manual manual method to calibrate and test the distribution network management terminal before leaving the factory. This method is complex, reliable and inefficient, and is not suitable for mass production. In order to solve the above problems, a universal automatic debugging and checking system for distribution network management terminal is developed in this paper. According to different types of terminals, the test and calibration requirements are flexibly configured to achieve high efficiency and high quality production. First of all, the system function mainly includes two aspects: data calibration and function test, among which, the function test mainly includes the analog quantity acquisition test, the switch quantity acquisition function test, the exit relay action test and so on. The whole testing process is controlled by the background software, and the test process is completed in strict accordance with the logical sequence before and after, and the test report is generated automatically and the voice prompt test is completed or abnormal. Secondly, according to the overall design of the system, the hardware and test control system is designed. The hardware design of the system is mainly intelligent I / O module, with ARM as the core processor, including the power module circuit E2PROM expansion circuit RS485 circuit, the switch input circuit and relay output circuit, and the communication interface between RS485 and E2PROM through Ethernet. The communication with the test control system is realized by the IEC-104 Modbus RTU protocol. The test control system is developed by Java platform and multitask mechanism, including test list module and man-machine interface. Among them, the test task is described by XML markup language to realize the standardized storage and reading of the test task, and the man-machine interface is constructed under the development environment of Netbeans using Java Swing development kit to realize the control and monitoring of the test. Finally, the feasibility of the system is verified by testing and calibrating different distribution network management terminals. The experiment proves that the fault identification of each function of the system has reached 100%, and meets the requirement of testing and calibrating the distribution network management terminal in the distribution industry. It has been successfully applied in the production process of the internal terminal of the enterprise. It has practical application value for terminal automatic test and inspection.
