Remote monitoring system for key points of electric power materials based on Internet of Things technology

Abstract

The present invention proposes a remote monitoring system for key points of electric power materials based on Internet of Things technology. The system includes a data acquisition module, a data analysis module, a data intelligent alarm module and an intelligent terminal module; the data acquisition module collects monitoring data of different data types Convert it into a unified data format, encrypt it, and send it to the cloud. Different data types of monitoring data include monitoring real-time data, data of conductor resistance and data of insulation extension length. Data analysis module The data collected by the data acquisition module is compared with the nominal value to obtain the deviation degree; when the deviation degree data is greater than the threshold value, an alarm is issued. The present invention forms a new material quality management mode of advanced control, real-time monitoring, intelligent analysis, and process control inspection, realizes on-site witnessing of electric power materials from multiple parties to remote real-time automatic monitoring, passive lagging supervision to active supervision, and reduces the labor intensity of personnel and labor costs, improving the efficiency of material quality management.

Description

technical field [0001] The invention belongs to the technical field of power material quality monitoring, in particular to a remote monitoring system for key points of power materials based on Internet of Things technology. Background technique [0002] Material management is an important support for power grid construction and production. Intensive management of materials is to coordinate planning and intensive management from the strategic height of sustainable development of State Grid Corporation to obtain maximum benefits at minimum cost. The safe and stable operation of the power grid depends on high-quality and high-quality power materials. Strengthening the quality control of materials used in the entire power grid is the basis and guarantee for improving material management and improving the safe and stable operation of the power grid. It is very important. The guarantee of material supply quality undoubtedly affects the security and stability of the entire power gr...

Problems solved by technology

[0004] The material quality management mode lags behind. The current material quality management method is the traditional sampling mode. The material quality management personnel go to the site to take samples, which has disadvantages such as scattered locations, low sampling efficiency, and small sample coverage.

In this sampling mode, there is a greater risk of unqualified materials flowing into the power grid, which brings hidden dangers to the safe and reliable operation of the power grid

The labor intensity of quality management personnel is high. At present, key equipment in power materials requires material management personnel to witness the key processes on site, which consumes a lot of manpower, material resources, and financial resources, and the locations are scattered, especially in power grid infrastructure and technical transformation in Jinan. , overhaul and other projects are increasing year by year, the amount of material procurement is increasing year by year, and the workload of witnessing is increasing sharply. On average, at least 2 people are needed for each witnessing, and it takes 3 days / person. Arranging and archiving requires offline manual operations; if multiple suppliers need key process witnesses at the same time, it will lead to heavy work intensity and tight working hours, making it difficult to meet business needs and affect delivery progress
