Problems solved by technology

Personnel safety accidents occur from time to time, and most of the reasons are that operators accidentally approach high-voltage live equipment or enter non-working live areas due to various reasons, resulting in personnel safety accidents
In addition, the occurrence of personnel safety accidents will also bring many uncertain risks to the normal operation of equipment.
[0006] (2) The typical illegal behavior of the operators in the station lacks intelligent early warning and preventive measures
Through on-site supervision or remote video supervision, it will be missed due to the restrictions of supervisors, and violations cannot be found in a timely and effective manner
In addition, this method is inefficient and expensive
[0007] (3) Lack of intelligent and effective control over the entire process from entering the substation to exiting the substation
It is not conducive to early warning of possible violations, nor can it provide evidence for subsequent investigations after accidents

Embodiment 1

[0055] The intelligent access control system 8 stores information such as the shift schedule, photos and names of the on-site operators of the substation, the license plate numbers and models of vehicles allowed to enter the substation. When the staff needs to enter the substation site, firstly, the image information of the staff is collected through the pan-tilt camera, and after preprocessing the collected image information through the image information preprocessing module 3, the image information processing system 2 identifies the personnel in the image information . If the person is not a staff member who can enter the substation on-site in the current shift, the intelligent access control system 8 controls the substation gate to close, otherwise the substation gate is opened. Or the image information processing system 2 recognizes the license plate number in the image information. If the recognized license plate number does not belong to the license plate number that can...

Embodiment 2

[0058] The intelligent access control system 8 also includes a document identification module, through which the ID card or work permit of the staff is identified. If the personnel identified by the image information is inconsistent with the photo information on the ID card or work card, the intelligent access control system 8 does not open the substation gate.

Embodiment 3

[0060] The image information processing system 2 judges that the staff in the image information does not wear safety protection equipment (the safety protection equipment includes a safety helmet and a safety vest) according to the collected image information, and the alarm system 5 judges according to the discrimination of the image information processing system 2 As a result, a voice alarm is given.

[0061] In the image information of high places where workers should not appear and non-working live areas, the image information processing system 2 recognizes that there are people present, and then judges that the person has illegally climbed to work and is located in a non-working live area. The judgment result of the processing system 2 is used to give a voice alarm.

Abstract

The invention provides a substation operation site safety management and control system based on visual perception and spatial positioning, and the system comprises: an image information collection module which collects the image information of a substation operation site; an image information processing system which is used for identifying field personnel in the image information based on a firstneural network model, judging whether the field personnel wears safety protection equipment or not, judging whether the field personnel carry out illegal climbing operation or not and judging whetherthe field personnel are located in a non-operation live-line area or not, wherein the image information processing system further identifies a license plate number in the image information based on asecond neural network model; UWB personnel positioning system which is used for obtaining the position information of the transformer substation operation field personnel, obtaining the motion trailof the transformer substation operation field personnel according to the position information, and judging whether the field personnel is located in a non-operation live-line area, whether the distance from the field personnel to the high-voltage live-line equipment is smaller than a set distance threshold value and whether boundary crossing work is carried out according to the position information.

Description

technical field [0001] The invention relates to the technical field of power system safety management and control, in particular to a substation operation site safety management and control system based on visual perception and spatial positioning. Background technique [0002] As the hub of the power grid, the substation plays an important role in the power system. It is the development trend of the power system to realize the unattended operation of the substation. In order to ensure the normal operation of the substation, the daily operation and maintenance of the substation is inevitable. On the other hand, with the rapid development of the power grid, more and more substations are newly built and expanded. How to ensure the personal safety of operators and operation and maintenance personnel in substations and the safety of substation equipment has become an increasingly prominent problem. [0003] At present, the substation auxiliary comprehensive monitoring system t...
