Remote free space light transmission method and system for forest fire prevention monitoring

Abstract

The invention provides a remote free space light transmission method and system for forest fire prevention monitoring, belongs to the technical field of optical communication, and aims at solving theproblems of remote transmission of remote forest fire prevention monitoring signals and network signal access. The system is composed of an Internet transmission terminal and a remote monitoring and network access terminal. The Internet signal is transmitted from the Internet transmission terminal to the remote monitoring and network access terminal via free space light. The network signal is accessed remotely, the real-time monitoring signal of the remote monitoring equipment is transmitted back to the Internet transmission terminal from the remote monitoring and network access terminal, andworking of the monitoring equipment of the remote monitoring and network access terminal can be remotely controlled by the Internet transmission terminal through the network. The free space light transmission technology is combined with network technology, real-time and controllable forest fire remote monitoring can be realized, network signal coverage can be carried out on the monitoring points,and the system maintenance ability can be improved. The method and the system are one of the best solutions for the private network in the forest area and have a quite broad application prospect.

Description

technical field [0001] The invention relates to a remote free-space optical transmission method and system for forest fire prevention monitoring, which belongs to the field of optical communication technology and can be applied to the field of remote signal transmission in remote forests and other environments without various network signal coverage. Background technique [0002] Long-distance unmanned environments, such as forests, mountains, islands, lakes, uninhabited areas, etc., currently have no network signal coverage, and rely on satellite communications and other facilities for information transmission. Forest fire prevention is the top priority in forest areas. Real-time video surveillance is of great significance to forest fire prevention. At present, my country mainly uses activities such as lookout and mountain patrol for forest fire prevention. It cannot monitor all forest-covered areas of major forest farms in real time. A lot of manpower. In recent years, a r...
