[0033] The security terminal management unit uses a two-dimensional plan view to monitor the location, manage the status, and coordinate the operation of terminal devices (cameras, loudspeakers, etc.).

[0046] The above-mentioned application process of the intelligent security system for substation production and operation based on digital scenarios is as follows:

[0047] Step 1: The smart terminal module starts up in conjunction with the system, initializes devices such as smart access control, cameras, and UWB positioning devices, establishes device communication links through the Internet of Things protocol, and completes hardware status self-check; each terminal collects video streams, personnel entry and exit records, environmental monitoring data (temperature, humidity, etc.) in real time, and after being cleaned and denoised by the data fusion processing module, it is transmitted to the central data pool for storage.

[0048] Step 2: The management cockpit unit displays the security situation of the municipal bureau / patrol and maintenance center based on the GIS map, and provides real-time statistics on personnel release volume and alarm quantity, and supports drill-down to view substation level details;

[0049] Step 3: The security terminal management unit monitors the status of equipment such as cameras and loudspeakers through the two-dimensional plan of the plant. When an offline terminal is detected, it automatically pushes maintenance personnel information and supports clicking on the terminal to trigger a linked announcement or video viewing.

[0050] Step 4: The intelligent early warning module analyzes the video stream and sensor data, identifies anomalies (such as infrared beam triggering), generates an alarm, and pushes it to the security personnel's cockpit; the security personnel review the video in real time through the cockpit, call the loudspeaker to drive away the suspects, and simultaneously record the processing results in the alarm management unit.

[0051] Step 5: When working at the substation site, the first step is to prepare for the operation. The qualification management unit verifies the qualification certificates of the operators and the vehicle safety records, and supports batch import of qualification data. The authorization management unit generates electronic authorizations for locks, tools, and access control based on the work order and issues them to the smart terminals of the operators. The remote authorization unit configures the audio and video parameters of the IoT terminal, associates it with the camera at the work location, and presets the capture points for authorization review.

[0052] Step Six: Monitoring During Operations. UWB positioning technology tracks the movement of workers. The electronic fence management unit detects whether workers have entered restricted areas. After triggering an alarm, the camera captures the image and pushes it to the operation monitoring unit. The safety behavior recognition module uses AI algorithms to identify behaviors such as not wearing a safety helmet and violating regulations, and automatically records violations. Workers initiate remote permit applications through smart safety helmets. The remote permit unit verifies on-site safety measures through audio and video calls, captures images to supplement permit information, and synchronously transmits it back to the power grid management platform.

[0053] Step 7: Conduct a post-operation review. The review and analysis unit summarizes authorization records, violation data, and trajectory information to generate a review report (such as an analysis of high-incidence points of violations in a certain work area), providing a basis for safety management optimization.

[0054] Step 8: The intelligent early warning module analyzes the camera video stream, identifies potential hazards such as circumvention of security walls and abnormal equipment overheating, and generates multi-dimensional early warning information by combining environmental data (such as sudden temperature changes); low-risk alarms (such as terminal offline) are automatically pushed to the security terminal management unit; high-risk alarms (such as personnel entering high-voltage areas) simultaneously trigger the broadcast loudspeaker and the electronic fence sound and light alarm, and notify the one-station-one-police management unit to coordinate with the police station.

[0055] In summary, the advantages of this invention are as follows: By deeply integrating various intelligent terminal devices such as smart access control, cameras, and smart safety helmets, it breaks the boundaries of traditional single-device applications, realizes intelligent application across all scenarios in substations, optimizes the collaborative operation capabilities between devices, and greatly improves the intelligent level of substation operation and maintenance management; by expanding the scenario application of the side-side production operation support system, it achieves intelligent control over all scenarios such as substation security, on-site operation safety, and maintenance process safety monitoring, reducing manual intervention, automating and intelligentizing alarm handling, reducing labor costs, and improving management efficiency; by integrating cutting-edge technologies such as artificial intelligence and big data analysis, it achieves real-time video monitoring through intelligent terminal devices to identify the safe operation behavior of workers, making the monitoring of workers' operation behavior more convenient and efficient, reducing human error and safety hazards, and improving the accuracy of early warnings.
