Figure 1 As shown, the system includes a production site monitoring point layer, a video intelligent analysis server, a smart IoT digital control platform, a duty room display and control system, and a duty personnel movement monitoring system. The specific implementation methods are as follows: The production site monitoring point layer is used to set up monitoring points at several locations on the production site, each equipped with a digital video surveillance system. This system includes intelligent cameras and hard disk recorders (DVRs). The intelligent cameras are selected based on the environment and monitoring needs of different areas, while the DVRs support multiple video inputs. Simultaneously, the monitoring lines utilize fiber optic transmission to optimize long-distance signal transmission links and are equipped with Category 6 unshielded twisted-pair cables, with anti-aging protection measures implemented. The core function of this layer is to collect video data from the production site and transmit the data to a video intelligent analysis server.

[0025] The video intelligent analysis server is an intermediate processing module connecting the production site monitoring point layer and the intelligent Internet of Things digital control platform, which carries an intelligent analysis algorithm module and has the functions of video data collection and behavior recognition analysis.

The server will perform abnormality detection and judgment on the received production site video data based on the above algorithms, and if it is determined that there is an abnormality, an alarm signal will be output to the intelligent Internet of Things digital control platform.

[0026] The intelligent Internet of Things digital control platform adopts a B / S architecture and has the functions of alarm receiving and processing, linkage strategy management, and device control scheduling. The platform also deploys a special data interface gateway, which can realize interfacing with the power plant DCS system, the steam pocket water level measurement system, the slag port system, and the flame television system, thereby obtaining the production operation data of these systems, including DCS parameters, steam pocket water level data, slag port system data, and flame television system data; and integrates a hyper-converged server for computing, storing, and integrating network resources. The platform will integrate the production site video data and the above production operation data, and then trigger linkage control to synchronize relevant information to the duty room display control system and the duty personnel mobile monitoring system.

[0028] In a preferred embodiment of the present application, according to the preset regional code and equipment code rules, the front-end camera equipment and the back-end processing equipment of different monitoring points are allocated with unique IP addresses, realizing accurate association of the equipment and data. Based on the IP address planning, corresponding video data viewing permissions are allocated to different levels of personnel according to a hierarchical authorization mechanism, ensuring the safety and pertinence of data viewing, and avoiding irrelevant personnel from obtaining sensitive monitoring information.

[0029] The video intelligent analysis server receives the video data of the production site, the intelligent analysis algorithm module is integrated in the video intelligent analysis server, and the intelligent analysis algorithm module performs video analysis and analysis through intelligent analysis algorithm. The intelligent analysis algorithm integrates a plurality of scene intelligent detection algorithms, specifically, through personnel behavior detection, non-compliance behaviors such as not wearing a safety helmet, falling down and not wearing a work uniform in the production site are recognized; through safety hazard detection, risk hazards such as smoking, checking goods and illegal parking are recognized; through regional safety monitoring, abnormal conditions such as illegal intrusion, boundary crossing and personnel retention are recognized; through object state detection, problems such as article moving, article leaving and fire passage occupation are recognized. When the intelligent analysis algorithm detects any one of the above-mentioned non-compliance behaviors or safety hazards, a video analysis result containing alarm position, alarm type, abnormal picture screenshot and the like is immediately generated, and an alarm signal is sent from the video intelligent analysis server to the intelligent internet of things digital control platform.

[0030] After receiving the alarm signal, the intelligent Internet of Things digital control platform triggers the preset alarm linkage mechanism, simultaneously links the on-duty room display control system and the on-duty personnel mobile monitoring system to carry out alarm prompt. The specific execution process of the alarm linkage mechanism is: the intelligent Internet of Things digital control platform automatically records the triggering time, alarm position, alarm type and corresponding complete video clip of the alarm signal, forms an alarm account; the on-duty personnel receives the alarm information in real time through the mobile monitoring system, and can feed back the alarm disposal state (such as "to be disposed", "disposal in progress", "completed") through the system; after the disposal is completed, the on-duty personnel uploads the disposal record and on-site rectification photos through the mobile monitoring system to complete the disposal closed loop; the intelligent Internet of Things digital control platform tracks the whole disposal process in the whole cycle, and if the disposal is not completed within the preset time limit, the system automatically sends a supervision reminder to the mobile monitoring system of the hierarchical management personnel, to ensure that the abnormal problems are solved in time.
