Wireless Monitoring Guarantee In Forest Areas
Aiming at the application scenarios of mountain terrain and vegetation coverage in forest areas, fixed nodes are deployed at mountain heights or relative heights in forest areas. They can also be deployed at the same address with public network base stations, which is convenient for installation and power supply. It can also be interconnected with the public network. The equipment does not need to be on duty. By means of self-interconnection and multi-hop relay, the disadvantageous factors of mountain area for wireless signal occlusion are transformed into the relay forwarding of commanding heights. So as to extend the communication distance, expand the coverage, reduce the monitoring dead angle and reduce the construction investment. Then the fire danger data and image information collected by each node equipment can be obtained. Real-time all-day return to forest management command center or satellite communication command vehicle. The remote command center can be transmitted back through the 3G/4G public network, which is convenient for the commander to view in time, scientific analysis.
The vehicle-mounted radio is installed on the satellite communication command vehicle and patrol vehicle, which is convenient for flexible networking with the commanding height fixed radio and patrol personnel. As a first-line command center, it can quickly enter the forest area, facilitate information collection, patrol monitoring and command dispatch, and provide wireless network support for the surrounding patrolmen. It can also interconnect with the satellite communication system and transmit the front-end field information back to the back-end monitoring command center for timely prediction, response and control of the fire situation on the spot.
Small and portable, with long battery life, it is easy for patrollers to carry. Especially when the fixed radio at the commanding height can not cover the area effectively or the vehicle radio can not reach the area, it can go deep into the forest area to carry out a sudden task. It is not only convenient for real-time voice communication with the commanders and other patrolmen on the surrounding vehicles, but also can transmit fire video images collected in the forest area as timely as possible. Provide comprehensive and clear on-site images to commanders at all levels.
Through the UAV-mounted image acquisition and the airborne self-organizing network node equipment lifting off, the mobile, efficient and fast accessibility can further expand the wireless coverage, reduce the coverage of blind areas, and improve the quality of video return; at the same time, air mobile monitoring and ground fixed monitoring can be organically combined, complementary advantages, forming a ground-to-air “three-dimensional” monitoring network. Better effective detection of fire detection and real-time monitoring while effectively increasing the visual range of the monitoring area and reducing the dead angle of monitoring.
