Intelligent safety supervision system of transformer substation and field operation safety management and control method

Abstract

The invention relates to a transformer substation intelligent safety monitoring system fusing multi-source safety state heterogeneous data and a safety management and control method. The transformer substation intelligent safety monitoring system comprises a three-dimensional laser point cloud model module, a work ticket management module, an intelligent access control management module, an electronic fence module, an intelligent violation identification module and an early warning management module. The invention discloses a field operation safety management and control method based on a transformer substation intelligent safety monitoring system. The method comprises the following steps: firstly, acquiring heterogeneous data such as personnel position data, field operation video monitoring, two-ticket text information, three-dimensional point cloud and the like by using a Beidou positioning technology, a video monitoring system, laser scanning and the like; then extracting text information of the two tickets by using a natural language processing algorithm based on RPNN, obtaining position information of an operation specified area, and realizing generation of a safety area based on the text information of the two tickets; combining the obtained three-dimensional point cloud data of the production site, and realizing analysis and alarm of an operation safety area through a Beidou positioning technology and a vector criterion; and finally, through a face recognition algorithm based on MTCNN, a target detection algorithm based on RefineNet and a semantic segmentation algorithm based on MaskRCNN, realizing risk recognition of typical violation behaviors of personnel. The system greatly reduces the safety risk of operators, saves human resources, reduces the operation and maintenance cost, and is of great significance for improving the intelligent management level of the transformer substation.

Description

technical field [0001] The invention belongs to the field of electric power safety management and control, and in particular relates to a substation intelligent safety monitoring system and an on-site operation safety management and control method that integrate multi-source safety state heterogeneous data. Background technique [0002] Substation is an important part of the power network, which plays an important role in transforming voltage, collecting current and distributing electric energy. On-site operation is a relatively complicated process, which involves many dangerous operations. The safety awareness and skill levels of electric power field operators are quite different, and various problems are prone to occur in the operation work. If they are not found and corrected in time, serious accidents will occur, which will affect the subsequent production work and the safety and stability of the power grid. run. [0003] At present, the conventional safety management ...

AI Technical Summary

Problems solved by technology

Whole-process monitoring of substation maintenance projects, daily management of non-production personnel in substations, etc., with heavy repetitive workload, high invalid labor rate, and low operating efficiency

[0005] (2) On-site supervision is easy to be neglected

At present, substations can only supervise illegal operations through personnel on-site inspections. There is a lack of prevention and timely notification of on-site civilized and safe construction violations. While consuming manpower, there are problems such as untimely data, difficulty in obtaining evidence, and omission of potential safety hazards.

[0006] (3) Single technical means of prevention

The technical prevention measures are completely implemented by personnel, which are relatively weak and have potential safety hazards, which need to be improved urgently
