【摘要】：用电现场状态检测是对现场用电设备的运行状态及用电设备采集的电力参数进行检测。目前用电现场状态检测通常采用手工或者笔记本电脑现场作业,人为上传检测信息的方式。这种工作方式无法满足国家对智能电网建设的要求,同时也给工作人员的工作带来不便,无法有效地对工作人员进行监督和管理,因此,需要改进现有的工作方式。本文根据用电状态检测的实际业务需求,通过分析目前用电现场状态检测系统的不足之处,提出一种基于嵌入式掌上电脑PDA的,实现智能化用电现场状态检测的信息管理系统的解决方案。通过Web Services远程通信技术和通信信息加密技术,实现了远程数据交换的安全和可靠,并通过设计数据库操作接口,实现数据的快速、准确导入。同时通过对系统的任务和操作流程进行设计,规范了检测工作任务流程,对工作人员起到有效的监督和管理作用。目前本文所设计的用电现场状态检测系统已经通过重庆、成都地区电力局的实际测试,测试结果表明,系统已达到设计要求,运行稳定。另外,对通信加密算法的测试表明其在PDA上有良好的表现,可以应用于实际的检测工作。
[Abstract]:On-site state detection is to detect the running state of the field power equipment and the electric power parameters collected by the power equipment. At present, manual or laptop operation is usually used to test the status of electricity on site, artificially uploading test information. This mode of work can not meet the requirements of national smart grid construction, but also bring inconvenience to the work of staff, and can not effectively supervise and manage the staff. Therefore, it is necessary to improve the existing working methods. In this paper, according to the actual business requirements of power state detection, by analyzing the shortcomings of the current power field condition detection system, a kind of PDA based on embedded palmtop computer is proposed. The solution of the information management system to realize the intelligent state detection of electric power field. The security and reliability of remote data exchange are realized by using Web Services remote communication technology and communication information encryption technology, and the fast and accurate data import is realized by designing the database operation interface. At the same time, through the design of the task and operation flow of the system, the inspection task flow is standardized, which plays an effective role in supervising and managing the staff. The system designed in this paper has passed the actual test of the electric power bureau in Chongqing and Chengdu. The test results show that the system has met the design requirements and run stably. In addition, the test of communication encryption algorithm shows that it has good performance on PDA, and can be applied to practical detection work.
