Project Brief: Given the severe current situation of forest fire prevention, to achieve early avoidance, early detection, and early control, it is necessary to deploy remote monitoring systems in forest areas.Due to the geographical characteristics of forest areas, deploying wired networks is extremely difficult. Wireless video monitoring, with its flexible configuration, rapid construction, high performance, and low cost, is being widely used in forest fire prevention.Utilizing the currently mature wireless communication technology, our company adopts an advanced wireless communication solution, combining wireless data transmission bridge technology and wireless backbone network transmission technology to build a wireless video monitoring system for forest fire prevention, meeting the practical application needs of forestry departments and town government safety management departments.

Utilizing the currently mature wireless communication technology, our company adopts an advanced wireless communication solution, combining wireless data transmission bridge technology and wireless backbone network transmission technology to build a wireless video monitoring system for forest fire prevention, meeting the practical application needs of forestry departments and town government safety management departments.

System Introduction: The monitoring management command center system is the core of the entire system, including image display, an intelligent fire image recognition system, and an intelligent fire monitoring and analysis system.This system can automatically detect fires and complete alarms in an unattended mode through the intelligent image processing system. If a smoke detection system is configured, it will send the signal back to the command center. The command center then controls nearby cameras to scan the suspected fire area based on the situation, and the intelligent image processing system detects fires in that area, issuing an alarm immediately once a fire is found.

The wireless transmission system includes wireless data transmission bridges and wireless backbone links.Wireless data transmission bridges are used to report video signals from multiple cameras to a central point within a small area.Wireless backbone links are used to transmit digital signals from various central points to the monitoring management command center at high speed.Through the flexible combination of wireless data transmission bridges and wireless backbone links, a large-scale signal network can be flexibly constructed to monitor large forest areas.ameras and PTZ control systems are front-end devices for video capture, with the function of converting analog video signals to digital signals for transmission. At the same time, the PTZ control system can also receive remote control signals to perform corresponding operations on the cameras, in order to provide clear observation video signals.

 The power supply system and poles provide installation positions, power supply, lightning protection measures, etc., for the cameras and wireless transmission systems.Solar cells are used for power supply.

In addition, depending on the specific situation, battery-powered individual mobile monitoring cameras and wireless transmission systems can be configured to move within the forest area for monitoring.Or, when a fire occurs, they can quickly collect on-site video signals nearby for superior leaders to assess the fire situation and deploy corresponding actions.

System Functions: The wireless long-range video monitoring system for forest fire prevention uses advanced wireless communication technology, overcoming environmental impacts to achieve real-time video monitoring in exceptionally complex forest areas, and immediately sends abnormal conditions back to command centers at all levels.The system has the following characteristics: 

a) The forest environment leads to a large monitoring range.

 When selecting monitoring points, cameras should first be installed at commanding heights in the forest, requiring a wide field of view, no obstacles, a large monitoring angle, and as few monitoring points as possible, maximizing the forest area covered by each monitoring point. If dead corners cannot be avoided, additional monitoring points can be added.At the same time, advanced wireless bridges are installed at the camera locations to instantly transmit video information of the monitoring range.

b) All-weather monitoring.

Monitoring points must work all-weather, requiring the selection of infrared-sensitive color-to-black-and-white cameras, day/night lenses, and outdoor integrated PTZs with screw drives. To reduce image jitter over long distances, the camera installation must also be firm and stable.

c) The video transmission link is the most critical part of the system.

Due to the specific characteristics of forest fire monitoring, transmission methods cannot use wired or fiber optic cables. HW wireless bridges become the most ideal wireless transmission solution.At the same time, wireless transmission offers advantages such as simple construction, low cost, and a one-time investment. It provides real-time, clear image transmission, selectable transmission frequencies, and power levels can be set as required based on transmission distance and on-site natural conditions.

d) Power supply for front-end equipment.

In forest fire monitoring systems, providing stable power to front-end equipment is very important.Therefore, when selecting monitoring points, priority should be given to locations with a fixed power source. If a suitable power point cannot be found, then solar power must be used.The solar power supply system consists of a solar cell array composed of solar cell modules, a solar charge controller, an inverter, and a battery bank.On sunny days, the solar cell array converts sunlight into electrical energy, powering the load while also charging the battery bank. When there is no sunlight, the battery powers the load.

e) Lightning protection and grounding must be safe and reliable.

The weakness of forest fire monitoring systems is the lightning protection and grounding of the front-end. The lightning protection and grounding of front-end equipment directly affect the safety and reliability of the entire project. Neglecting them will bring huge losses to users. The principle of lightning protection is that all equipment must be installed within the protection range of lightning rods, with grounding resistance not exceeding 10 ohms. To detect fire alarms promptly, the front-end needs sensors such as smoke detectors and alarm linkage equipment. 

f) Wireless monitoring system products must have high reliability.

Since the entire monitoring front-end equipment is located deep in the mountains, making maintenance extremely inconvenient, the center must be able to grasp the working status of the front-end equipment at any time, which will play an important guiding and analytical role in maintenance.Therefore, wireless bridges with excellent performance are crucial. HWs wireless bridges are industrial-grade standard products, capable of adapting to outdoor harsh climatic environments, maximizing the stability and reliability of the entire wireless system.
