Intelligent patrol inspection system and method for power distribution network based on internet of things

Abstract

The invention provides an intelligent patrol inspection system and method for a power distribution network based on the internet of things. The method comprises the following steps: the inspection personnel logs in an intelligent inspection terminal through an NFC identity recognition module and receives an inspection task and an inspection path integrated optimization strategy; the inspection personnel performs patrol inspection according to the inspection task and the inspection path and recognizes the equipment identity and performs navigation through a "GPS + Beidou" dual-mode positioningmodule; The equipment state information is acquired in real time by a professional sensor acquisition module and an information storage and processing module and stored, preprocessed and uploaded; andthe background application realizes the power distribution equipment state evaluation and diagnosis according to the uploaded state data and generates the next inspection path integrated optimizationstrategy according to the equipment state, the network topology and the geographic information. The drawbacks of low informatization level and high workload of the existing patrol inspection mode canbe overcome, and the quality and the efficiency of power distribution network patrol inspection can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of intelligent inspection of distribution networks, in particular to an intelligent inspection system and method for distribution networks based on the Internet of Things. Background technique [0002] At present, China's distribution network inspection mainly has the following problems: First, the distribution equipment has many points and a wide area, and inspection personnel need to hold various drawings and report forms on the spot to copy, and later, a large amount of manpower needs to be invested to re-enter the inspection data into the system. The speed is slow, the workload is heavy, error-prone, and the data is inconvenient to save and query; second, the inspection workload is heavy, the working hours are long, and subjective work mistakes are inevitable, and there is also a lack of supervision of the staff during the inspection , it is difficult to guarantee the quality of inspection; third, the in...

[0002] At present, China's distribution network inspection mainly has the following problems: First, the distribution equipment has many points and a wide area, and inspection personnel need to hold various drawings and report forms on the spot to copy, and later, a large amount of manpower needs to be invested to re-enter the inspection data into the system. The speed is slow, the workload is heavy, error-prone, and the data is inconvenient to save and query; second, the inspection workload is heavy, the working hours are long, and subjective work mistakes are inevitable, and there is also a lack of supervision of the staff during the inspection , it is difficult to guarantee the quality of inspection; third, the inspection operation lacks a unified standard process, the inspection strategy and inspection tasks need to be manually formulated, and the inspection path is also freely played by the inspection personnel. Due to the influence of the technical level of the personnel, important inspection items are prone to appear Fourth, the state information of power distribution equipment is insufficiently obtained, and at the same time, due to the lack of a unified information data interface and state data processing technology on site, the continuity and accuracy of the state maintenance work cannot be guaranteed, and it is difficult to Prompt and guide inspection personnel to actively carry out status assessment, defect identification and diagnosis. The above problems have greatly affected the quality and efficiency of inspection work
