With the continuous advancement of forest protection and forestry construction, the forest area and forestry stock volume have increased year by year, and the fire prevention task has become more and more arduous. Forest fires are characterized by strong suddenness, random occurrence, and huge losses in a short period of time, so once they occur, they must be quickly extinguished. Therefore, it is necessary to comprehensively improve the coverage of forest fire prevention communications to ensure that information transmission can be smoothly transmitted through various communication means during daily work and when fires occur.

BelFone  Communications provides fire rescue solutions in helping forestry patrol and fire rescue. The solution has the following highlights:

1. With the help of the converged communication platform, different communication networks are integrated to realize upper-level converged communication, converged command and other services based on intercommunication needs.

2. Integrate multi-form and multi-standard terminals to uniformly manage and dispatch multi-mode terminals, smart terminals, audio and video recording terminals, radio terminals, etc.

3. Terminal can report service by time and location. Combined with GPS, it can clearly grasp the personnel reporting location, patrol path, etc.

4. use lightweight, portable radio that can follow rescuers into the core rescue area to ensure the "last mile" communication of the rescue site.

Forest patrol

In forestry patrol work, forest patrol mainly covers two aspects: daily patrols around the village and key visits to high-risk points for wildfires.

As for daily patrols around the village, there is usually good public network signal coverage. Forest rangers carry public network walkie-talkies or public-to-public integrated communication equipment for patrol work, which can realize daily patrol calls, such as timely reporting of tree diseases and pests, and timely and accurate reporting of on-site conditions to the command center. For high-risk points for wildfires, narrowband conventional networks are usually used to build backup networks. On the one hand, this can meet the daily communication needs in an environment without a public network. On the other hand, during the high incidence of wildfires, with the help of narrowband conventional network backup networks, it can effectively ensure smooth communication between rescue personnel and effectively respond to emergencies.

In addition, due to the vast area of forests, there are often cases of wrong patrols, missed patrols, no patrols, and even missing personnel. Therefore, communication terminals can be used to collect positioning data, online data, communication data, and on-site multimedia data.

Forest fire rescue

When a fire occurs, forest fires are fierce and dangerous. The mountain fire site is high and dense, the terrain environment is complex, and there is no public network coverage. On-site firefighters and firefighting forces often face challenges such as "unable to see clearly, unable to hear, many blind spots, and high danger".

At the forest fire site, the TR925 series narrowband self-organizing network is used to complete the on-site voice communication coverage, and the Mesh broadband self-organizing network equipment is used for multi-hop cascading to cover the on-site broadband private network signal. At the same time, broadband and narrowband relay points are set up at high points in the mountainous area, and aerial drones are used to carry relay equipment to further expand the on-site emergency network communication signal coverage. Rescuers are equipped with multi-mode terminals, digital radios, and explosion-proof terminals as audio and video communication equipment. Through the self-organizing network at the rescue site, these front-line rescue data can be transmitted back to the front command center in real time, and then transmitted back to the rear command center via satellite links and 4G/5G networks for analysis and prediction, providing accurate information support for firefighting decisions.
