An access control system and its identification method applied to substations

Abstract

The invention relates to an access control system applied to a substation and an identification method thereof, comprising an image acquisition device, an image identification module, and a memory; the image acquisition device is used to acquire image information of people and / or vehicles passing through the access control; the image identification module It is used to extract the identification features in the image information; the memory is used to store the standard identification features; when the image recognition device extracts the identification features, and the extracted identification features match the standard identification features, the corresponding person and / or The car passes. By identifying and comparing the characteristics of the staff and vehicles in the power system, the present invention can enable the personnel in the power grid system to easily enter the substation, and block other personnel or give reminders and warnings to staff who do not conform to the regulations; at the same time, the invention The invented access control does not need to build a huge database and execute complex and precise identification algorithms, which reduces the cost of equipment, improves the efficiency of access control, and improves the degree of automation.

Description

technical field [0001] The invention relates to an access control system applied to a substation and an identification method thereof, belonging to the field of intelligent substations. Background technique [0002] With the promotion of smart substations, unattended and intelligent inspections have been realized inside the substation, and the camera system currently installed in the substation can also realize functions such as security monitoring. However, the intelligence of the access control system of the substation is not perfect, and there are many defects. The door lock using the key is used as the access control, and only individual managers can carry the key. It is very inconvenient for personnel to be present; access control using passwords requires personnel to manually enter passwords, and substation workers often need to wear heavy insulating gloves during work, and their hands are easily stained with oil, and sometimes they need to carry or carry tools or equi...
