【摘要】：配网管理终端作为配电系统的执行单元,连接着配电主站和配电一次设备,它的实时性、可靠性、精度等直接影响着配电系统的安全和可靠运行。过去,国内外大多生产厂商采用人工手动方式对配网管理终端进行出厂前的校准、功能测试,这种方式步骤复杂,可靠性和效率低下,不适用大规模批量生产。针对上述问题,本文研发一种通用型配网管理终端自动调试及检验系统,根据不同类型的终端灵活配置测试与校准要求,实现高效、高质量的生产。首先,系统功能主要包括数据校准和功能测试两个方面,其中,功能测试主要包括对配网管理终端的模拟量采集测试、开关量采集功能测试、出口继电器动作测试等。整个测试过程由后台软件控制,严格遵循前后逻辑顺序完成测试过程,并自动生成测试报告及语音提示测试完成或者异常。其次,根据系统的总体设计方案,完成了硬件与测试控制系统的设计。系统的硬件设计主要为智能I/O模块,以ARM为核心处理器,包括电源模块电路、E2PROM拓展电路、RS485电路、开关量输入电路以及继电器输出电路,通过以太网与RS485通信接口,以IEC-104、Modbus_RTU协议实现与测试控制系统的通信。测试控制系统通过Java平台,采用多任务机制开发,包括测试列表模块和人机界面。其中,测试任务采用XML标记语言描述,实现测试任务标准化存储及读取,人机界面则利用Java Swing开发包在Netbeans的开发环境下构建,实现测试的控制与监视。最后,通过对不同种类的配网管理终端进行测试与校准,验证了系统的可行性。实验证明了系统对各个功能的故障识别达到了100%,且符合配电行业对配网管理终端的测试与校准精度要求,成功应用于企业内部终端的生产过程中,对终端自动测试与检验具有实际应用价值。
[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.
