LPWAN-based distribution staus remote monitoring system and method thereof

Abstract

The present invention discloses a LPWAN-based distribution status remote monitoring system and a method thereof. The distribution status remote monitoring system includes a power distribution transformer status monitoring apparatus distributed in the field, an LPWAN access base station, an LPWAN core network, and a power company monitoring main station. The present invention is based on Internet of Things sensing, status signal collection processing, and a principle of a remote communication technology. A plurality of sensors and monitoring terminals are mounted on the side of the monitored power distribution transformer. The sensor collects environment and operating status parameters of the distribution transformer in real time, and a built-in processor of the monitoring terminal analyzesthe status data in real time. When a threshold crossing alarm occurs, alarm information is reported to a power company monitoring center by using the low-power wide area network (LPWAN), to implementremote alarm, and remind an operation and maintenance personnel to go to the site in time to perform processing, so that intelligent and automatic operation and maintenance management of a power distribution device in the production field is implemented.

Description

technical field [0001] The invention relates to the communication field of computer internet of things, in particular to an LPWAN-based remote monitoring system and method for distribution transformer status. Background technique [0002] The number of distribution network equipment is large, the distribution range is wide, and the communication environment is complex, such as the wall penetration problem of urban underground distribution network communication, and the long-distance communication problem of rural power distribution equipment monitoring. Conventional optical fiber, wireless, and power carrier communications are limited by problems such as communication distance, performance, construction cost, and on-site power supply. At present, only the "three remote" data communication of secondary automation equipment in the distribution network has been realized, while a large number of power distribution equipment For example, the operation status of line equipment suc...

Problems solved by technology

However, the short-distance wireless communication technology has the following problems: 1) The single-hop communication distance of the short-distance wireless communication technology is short, and complex networking technology is required to expand the network coverage, and the distance between monitoring nodes such as rural power distribution equipment status monitoring is relatively long In the environment, it is necessary to deploy additional relay nodes to expand the network coverage; 2) In addition to WLAN technology, other short-distance wireless communication technologies usually use ad hoc network communication, and the number of power distribution equipment is large and the types of monitoring data are diverse. , which is not conducive to improving network efficiency, ensuring business service quality, and brings great challenges to network management; 3) The short-distance wireless communication system has poor wall penetration performance and is not suitable for the state of the urban underground distribution network environment Monitoring; 4) The security, reliability and practical level of short-distance wireless communication networks need to be improved
