1. Background requirements
In some remote areas, there is also a need for video surveillance. However, in this type of scenario, it is generally not possible to obtain mains power nearby. If mains power needs to be pulled over a long distance, the construction cost is very high and long-distance transmission has safety risks. Therefore, there is also a greater demand for wind and solar complementary remote video monitoring solutions. The principle of wind-to-electricity conversion is used to provide power supply for video surveillance equipment in remote or power-free areas, thereby meeting the power demand of video surveillance networks in remote areas. There is no need to dig trenches and bury wires, power transmission and transformation equipment, no electricity consumption, and low maintenance costs.
2. Overview of wind and solar complementary remote video monitoring solutions
The plan uses wind energy and solar energy as the main power supply sources, and cooperates with an efficient and lightweight lithium battery energy storage system to power monitoring equipment or store it in batteries. This can achieve energy self-sufficiency in the absence of conventional power sources, and is especially suitable for Applications in remote and powerless areas.
Based on wind power generation, solar power generation + storage battery, it provides power for front-end monitoring equipment, effectively solving the problem of "difficulty in obtaining power" in the scene. It uses 4G/5G traffic cards to solve network needs, and can smoothly and conveniently transmit the video stream of the front-end camera to EasyCVR video fusion and sharing. Intelligent monitoring platform.
The national standard GB28181 security monitoring system EasyCVR platform adopts an open network structure and can support 4G, 5G, WiFi, wired and other methods for video access, transmission, processing and distribution. To ensure the effectiveness of remote video surveillance, the following two methods can be used:
1) Use solar cell modules to solve the power supply problem. Convert sunlight energy into electrical energy on a clear day, which not only supplies power to the load, but also charges the battery pack.
2) The wind turbine uses wind energy to drive the fan blades to rotate, thereby generating electrical energy. The generated electric energy is stored by energy storage equipment (such as lithium batteries, gel batteries) for subsequent use. The stored electric energy is converted into alternating current through an inverter to provide stable and continuous power supply for monitoring equipment. The fan uses an axial fan, and the battery pack uses low-temperature-resistant gel batteries. The battery pack can be buried underground or stored in a sturdy battery room.
3. Functional features
1) Network communication and remote monitoring
The intelligent video surveillance system EasyCVR platform can unified access and convergence management of massive network surveillance devices scattered in the scene in complex network environments such as local area networks, public networks, and private networks, and can provide real-time remote video surveillance, video recording, Rich video capabilities such as video playback and storage, alarms, voice intercom, PTZ control, platform cascading, disk array storage, centralized video storage, and cloud storage.
In terms of network transmission, the platform supports devices to quickly transmit video streams through 4G, 5G, WIFI, wired and other methods. After the video streams are processed by the platform, they can be distributed in multiple formats to enable viewing on multiple display terminals (computers, large screens, TV wall, mobile terminal, etc.). The national standard GB28181 protocol EasyCVR security platform can play multiple video streams at the same time, with 1, 4, 9, and 16 video screens available, and supports video carousel. The accessed video surveillance resources are released to the outside world through the EasyCVR streaming media server, and leaders and government departments at all levels can access relevant videos and data in real time based on their authority.
2) Video storage and playback
The platform can perform 7*24H recording according to business scenarios, supports cloud recording/device recording, and supports video retrieval and playback. Surveillance video recording data can be stored in a variety of ways. Supervisors can view video recordings at any time, conduct spot checks and playback, and conduct video review and traceback of abnormal events.
3) GIS electronic map
The monitoring platform EasyCVR supports GIS electronic map mode. Based on the longitude and latitude geographical location information of the surveillance camera, the overall security control in the scene is presented in the form of a visual map. Managers can conveniently and quickly call the surveillance video images of the points.
4) Equipment management and status monitoring
The platform can centrally access and manage devices in all areas, and supports multi-level grouping of device trees, permission/role assignment and management, etc. The front-end nodes are network cameras, which maintain IP communication and heartbeat keep-alive with the EasyCVR video platform. EasyCVR can monitor the operating status of the equipment in real time and issue alarm messages for equipment that is working abnormally.
5) Permission management
The security monitoring platform EasyCVR has clear permissions and user role management. For different permissions, you can log in to the web terminal with different permissions through authorization to control the camera pan/tilt and lens, preview real-time surveillance images, view video recordings and other functions.
6) AI intelligent detection
The AI algorithm based on the intelligent analysis gateway V4 can also realize intelligent analysis and recognition of AI videos in monitoring scenarios. For example, in forest fire monitoring scenarios, by deploying AI fireworks recognition algorithms, forest fire hazards can be monitored in real time and given early warning, which is convenient for management departments. be processed in a timely manner. In water conservancy monitoring scenarios, intelligent supervision of water conservancy facilities and dangerous waters can be achieved by deploying AI algorithms such as regional intrusion algorithms, perimeter intrusions, and cross-border intrusions. In the power inspection scenario, through the detection of personnel dress code (hard hat/reflective clothing/work clothes/work hat), personnel behavior detection (falling, crossing the line, smoking, etc.), pyrotechnics detection, abnormal camera displacement detection, etc. Intelligent supervision and supervision of power inspection scenarios ensure the safety of on-site maintenance and inspections.
The intelligent analysis gateway (V4 version) deploys nearly 40 AI algorithm models, supports real-time detection and analysis of people, vehicles, objects, behaviors, etc. on accessed video images, reports recognition results, and can play voice alarms. After the algorithm is configured, real-time detection of surveillance video streams can be performed, including safety helmet/work clothes detection, person falling, mobile phone playing/calling detection, area people counting, area wandering detection, etc. When an event is detected, an alarm will be triggered immediately, a snapshot will be taken, and an alarm message will be reported. Alarm messages can be reminded through pop-up windows, beeps, etc., making it easier for managers to view them in a timely manner.
7) Resource sharing
The video surveillance platform EasyCVR system supports the unified aggregation and cascading of video resources through standard protocols and standard API interfaces. By connecting the video surveillance resources to the superior supervision center, it can achieve the purpose of resource sharing and multi-department collaborative supervision.
TSINGSEE Qingxi wind-solar complementary video surveillance can realize functions such as video surveillance, data collection and transmission, energy supply, remote supervision and control. The front-end monitoring system does not require staff to be on duty, and the back-end can realize remote video monitoring, intelligent monitoring, and monitoring anytime and anywhere through a PC or mobile phone. An efficient remote monitoring system.
