And (3) processing information of various remote permission devices in the network after the remote permission network is accessed, wherein the information comprises an identity recognition device, a license plate recognition camera, a face recognition camera, a technical and defense system, an electric door control system and the like. Meanwhile, the terminal is provided with a DIO interface, can control devices such as flexible locks and magnetic locks, and can control an electric door control system and a technical prevention system through a remote permission network. Therefore, the purpose of remote signaling and remote control of the transformer substations in various regions through the service system is achieved.

Description of the preferred embodiments

Fig. 1 is a schematic diagram of the system architecture of the present invention, which is an introduction of the components of the whole remote licensing system. The following is a description of each part:

1) an identity recognition device with multiple identity recognition such as face recognition, identity card recognition, work recognition and the like is configured at a gate of a transformer substation or a main station house, and remote station house admission is realized by combining remote application. The outdoor protection level requirement is fully considered in the design of the identity recognition device, and anti-theft and anti-damage measures are made.

2) The electric lock or the intelligent lock is transformed for the transformer substation gate or the main door room lock, and the authorized door opening is realized through the intelligent access control.

3) And a camera special for license plate recognition is configured to recognize and compare the incoming vehicles. Other field cameras can fully utilize the original security and production monitoring cameras.

4) And an intelligent camera specially used for face recognition is configured, and face recognition and qualification audit are carried out on all the persons entering the station.

5) And the technical defense system and the like realize the functions of technical defense withdrawing and defense deploying, abnormal alarm and the like. And the system adopts a unified and standard communication protocol to communicate with the service system, and completes various remote permission works by combining remote application.

As shown in fig. 2, it is a service software flow chart of the present invention, which shows the remote signaling and remote control functions of the remote authorization terminal in a specific process of a single remote authorization service. The remote license service procedure is described in detail below in conjunction with fig. 2:

in step 401, the service providing system issues task information, including personnel information and license plate information of the task, and then executes step 402;

in step 402, the job principal of the construction unit sends an entrance application through the handheld terminal, and then executes step 403;

in step 403, the remote permission terminal issues the personal information to each of the identity authentication device and the intelligent identification device. Then step 404 is performed;

in step 404, the job principal of the construction organization swipes the job card (ID card) and scans the face of the person, and the job principal authentication is performed. Then step 405 is performed;

in step 405, two situations occur, when the work person in charge fails to authenticate, step 406 is executed, and if the authentication succeeds, step 407 is executed;

in step 406, the identity authentication device captures the live photo and sends the captured live photo to the remote permission terminal, and the remote permission terminal generates an alarm and sends the alarm to the service system.

In step 407, the work licensor receives the successful authentication message, sees the picture of the on-site personnel, compares the picture with the personnel in the system, and after confirming that the on-site personnel is the construction responsible person, starts the power station gate through the handheld terminal, and then executes step 408;

at step 408, the remote approval work is completed and the construction crew begins the job-site. Then steps 409, 410, 411 are performed respectively;

in step 409, the license plate recognition intelligent camera captures the license plate information and the vehicle photos captured on site, and sends the license plate information and the vehicle photos to the remote permission terminal, and the license plate information and the vehicle photos are analyzed and compared by the device to verify the validity of the license plate. Step 415 is then performed;

in step 410, the face recognition intelligent camera captures the personnel information and personnel photos captured on site, analyzes and compares the personnel information and personnel photos, and then sends the recognition result to the remote permission terminal, and the terminal verifies the validity of the personnel through analysis and comparison. Step 415 is then performed;

in step 411, the job licensor authorizes the openable area in the task through the handheld terminal or the web client. Then, step 412 is performed;

in step 412, the job principal of the construction unit arrives at the area where the job is to be performed, and the job card (identity card) and the face are swiped through the identity authentication device for authentication. Step 413 is then performed;

in step 413, the remote permission terminal analyzes the identification result of the id device, verifies the validity of the person, and allows the person to enter the area. Then step 414 is executed;

in step 414, the remote admission terminal analyzes and controls the DIO interface and controls the electric control door. Step 415 is then performed;

in step 415, the construction unit completes the job task, and the job principal initiates a task completion application through the handheld terminal. Then step 416 is executed;

in step 416, the remote permission terminal receives the task ending command, and checks the door state and the protection system state in the station. If there is no one-time condition, go to step 418, if there is an abnormal condition go to step 417;

in step 417, the remote permission terminal sends a message that the door house is not closed or the defense system is not armed to the service system;

in step 418, the construction unit work responsible person initiates an off-site application through the handheld terminal, after the work licensor passes the verification, the service system issues a task off-site message to the remote licensing terminal, and then step 419 is executed;

in step 419, the remote permission terminal deletes the information of the personnel on the identity authentication device and the intelligent device according to the issued task work ticket information, and ends the remote permission process.

The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
