2. The substation entering authorization management system according to claim 1, further comprising an intelligent gateway, wherein the intelligent gateway is respectively connected with the video image recognition device, the work ticket management module, the database, the authorization management platform and the door control device, and is used for realizing information acquisition and information transmission among the video image recognition device, the work ticket management module, the database and the authorization management platform, and sending control instructions output by the authorization management platform to the door control device.
3. The substation entering authorization management system according to claim 1, wherein the work ticket information includes work content, department information, personnel information, and personnel qualification requirement information, wherein the department information includes department identification, superior departments, affiliated sites, and site locations; the personnel information comprises personnel names, certificates, positions, qualification, departments and face photos; the personnel operation qualification information includes personnel qualification certificate information.
4. A substation entry authorization management system according to claim 3, wherein the specific steps of video image acquisition and identification of the entry security identification area include:
Acquiring face images of people entering an inbound security recognition area, and performing feature recognition on the acquired face images based on a deep learning face recognition model to obtain feature images of the face images; invoking personnel information from a database, and matching the feature images of the face images with the face photos in the personnel information one by one, wherein when the feature images are successfully matched with the face photos, the personnel entering the inbound security identification area currently are represented as operating personnel; and when the face images are not matched with each other, judging that the face images are not matched with each other, and the authorized management platform is not released.
5. The substation entering authorization management system according to claim 4, wherein the authorization management platform searches information of a target work ticket and/or a target person according to a field through a fuzzy search algorithm when reading work ticket information and personnel operation qualification information from a database; and the authorization management platform sends the matched work ticket information and personnel operation qualification information to the door control equipment for display.
