China's local forest fire situation very difficult climatic conditions extremely unfavorable, forest fire danger rating increase further; forest fuel prominent increase the risk of forest fire; fire management further very difficult, the risk of forest fires.
Last year, China's winter weather, the continuous high temperature low drought and precipitation, in the South part of the provincial forest fire weather rating high, forest fires, key regional proliferation of Hunan, Jiangxi, Guizhou, Fujian, Sichuan, Yunnan, and fires more grim.In the face of each such grim situation of forest fire prevention, national leadership management departments require more around the application of science, advanced technology and management methods, the most effective measures, as far as possible on forest fires from occurring and spreading to maximize control, do it early to avoid, early detection, early control.
In recent years, the rapid development of video surveillance application forest fires in the Defense has also played an increasingly important role, since forest area terrain, area great reasons, in forest areas difficult to deploy wired network, wireless video monitor with its flexible configuration and building a fast, efficient, low-cost, performance, etc. are widely used in forest fire prevention.In response to the urgent needs of forest fire prevention, focusing on video surveillance professional wireless transmission brand — BITWAVE, using the most advanced wireless technology — wireless network bridge, build a suite of advanced forest fire wireless video surveillance system, to meet the needs of the forestry sector and Security Department of practical application.
BITWAVE wireless monitoring system of forest fire prevention
BITWAVE wireless monitoring of forest fire monitoring system, the forest monitoring management command center system, wireless transmission systems, camera and PTZ control system, very sensitive smoke systems, power systems and the Eiffel Tower.
Forest monitoring management command center system is a core part of the entire system including the image display, video system, fire smart image recognition system, intelligent fire monitoring and analysis system. The system can unattended by image intelligence system, you can auto-discovery of fire, auto-complete alarm and smoke systems will assure signal back to the command center, command centers and then automatically control the nearest camera to scan a suspicious fire zone, the intelligent processing system complete the image of the area of fire for reconnaissance, once found to fire alarm at the first time.
BITWAVE forest fire wireless monitoring system adopts advanced wireless communication technology that spans environmental impact, at anomaly complex forest environment in real time video surveillance, and the first time the forest area of exception back to the levels command center.
In this system, according to the actual needs of forest fire, the system has the following characteristics:1. forest-environment causes the monitoring range.
Selection of monitoring points, first cameras should be installed in the forest, require a wide field of view, accessibility, monitor viewing angle, minimum set monitoring points, and as far as possible so that each control point monitoring coverage of the largest forest area, such as the unavoidable with dead ends, can increase the monitoring point. At the same time, the location of the camera to erect install BITWAVE advanced wireless network bridge, instant feedback monitoring range video information.2, 24 x 7 monitoring.
Monitoring points to work 24/7, the need is to select the camera you should use an infrared-sensitive camera color go black and white; lens should use dual-purpose type lens, day and night and outside 3KM can see figure; head requires selection of screw outdoor integration head, in order to reduce long-distance image dithering camera installations to ensure the secure and stable.3. video transmission link is a system in the most critical component.
As a result of forest fire monitoring their own characteristics, transmission is not possible to use wire or cable, BITWAVE wireless bridge becomes the most ideal wireless transmission solutions. At the same time, the wireless transmission mode with easy, low cost, one-time investment advantage, real-time image transmission, clear, transmission frequency optional, and may, in accordance with the transport distance, onsite natural conditions, its power can be asked in the preparation, in the event of obstruction, can be set up relay system or the use of low-frequency bridge directly through a certain density of trees.4. forest fire prevention, involving a wide range of distance.
The need for monitoring of forests and monitoring center distance, the more decentralized distribution. In the forest fire prevention system BITWAVE, usually mixed with 5.8G product 2.4G networking mode. For the distribution point used by dense 5.8G distal point-to-multipoint networking mode; for the individual distance of distal point can use 2.4G product networking, for some visual environment not good monitoring points, you can use a low frequency diffraction and penetrating ability of products.5, front-end devices.
In forest fire monitoring system, to provide a stable for the front-end device power is very important. Therefore, in the select a monitoring point, try to consider choosing a fixed power, but we will consider to have the power of monitoring point is far from the Centre, it reflects the long-distance transmission of wireless devices. If you cannot find a suitable active points, you can only use solar power supply. In the use of solar power, first of all, you want to select a professional solar power supply products; secondly, the solar power system at least guarantee in wet weather, can give each control point of the front end all devices provide 24 hour electricity. Solar power from solar cell components of solar cell, solar charge controller, inverter, batteries. Solar on a clear day the Sun cannot be converted to electrical energy, the power supply to the load, but also to the batteries charge; in the absence of light, power supply from batteries to load.6, lightning earthing to safe and reliable.
Forest fire monitoring system of soft rib is a front-endLightning protection and grounding of the, front-end equipment grounding lightning and directly affects the entire works of security and reliability, the neglect of lightning and grounding will give the user a tremendous losses, the lightning is all equipment must be installed in the lightning protection, Earth resistance not more than 10 Ohm, such as contractors do not have lightning and grounding, recommendations and local professional lightning protection and grounding, lightning protection and cooperation of its characteristics is the grounding for the environmental impact of the decisions and to effect the actual lightning, so detached from the seat of the specific circumstances of the project and design lightning and grounding is unrealistic and impractical.7, for the timely detection of fire, smoke, etc. are needed in front of the sensors and alarm equipment.
8, wireless monitoring and control system products with high reliability.
Because the monitoring equipment is located in the mountains, in front of the maintenance is extremely inconvenient, so the Centre to be able to grasp the front-end device status, maintenance will play an important role in guiding the analysis. Therefore, the performance of a wireless network bridge is critical to BITWAVE wireless network bridge is the industry-standard products, outdoor weather environment, while at the same time by the national radio Committee strictly detects and approved, you can maximize the guarantee that the entire wireless system stability and reliability.By BITWAVE forest fire prevention wireless surveillance system, you can build advanced forest fire warning system, improving on sudden forest fire monitoring and disposal capacity, research and exploration to strengthen surveillance, prevention of forest fires, command, suppression of effective ways to further establish and improve scientific prediction of forest fires early warning system and response management system, and constantly improve forest fire protection plans, building up as soon as possible and adapted to the forest fire prevention mechanism to fundamentally improve the forest fire prevention, suppression and integrated capabilities.
