基于载波通信的低压用户串户检测仪的设计

Design of the Low-voltage User Missort Fault Detection Instrument Based on Carrier Communication

针对目前供电服务过程中经常出现的低压用户串户现象,研制了一种基于载波的可广泛应用于电力行业检查居民住宅楼的用电线路串户的智能检测仪器。该文提出了系统的整体设计方案和设计原理,主要采用了主从机载波通信技术、多路检测技术、错接线综合判别技术、主从机人机互动技术等,分别对主、从机的设计原理进行了阐述,对主、从机的软件设计流程进行了简要说明。现场对比试验表明,该仪器提高了现场排查人员的检测准确率及工作效率,降低了劳动强度,具有很强的实用价值。

For the low-voltage user missort fault phenomenon occurred frequently in current supply service,the intelligent detection instrument has been developed which is widely used in the power industry to check power lines missort fault of residential building,it is based on carrier wave technology. This paper described the necessity of developing the device,put forward the overall design scheme and design principle of the system,respectively set forth the design principles of the master machine and slave machine ,briefly explained the software design process of the mas- ter machine and slave machine,and introduced the operational approach of the master machine and slave machine. Small wireless communication technology,multi-channel detection technology,wrong wiring comprehensive discriminate technology,master-slave machine man-machine interactive technology,etc have been mainly used in the design. The site comparison test has proved that the equipment can improve the work efficiency and the detection accuracy of the spot inspector,reduce labor intensity,has great application value.
