During the spring and summer seasons, the task of forest fire prevention is extremely challenging. The prevention and control of forest and grassland fires has entered a critical and decisive stage. The combination of high temperatures, drought, and strong winds has led to an increase in fire hazards, including the accumulation of flammable materials under the forest and grass and illegal use of fire in the wild. The pressure for fire prevention and control has sharply increased.

Currently, there are widespread issues in the forest area where public network coverage is insufficient, and communication signals in mountain and forest areas are intermittent or even non-existent. Traditional communication methods are unable to support emergency operations in the field. Based on broadband self-organizing network equipment as the communication foundation, combined with detection drones, infrared pods, and visual command systems, the entire process of fire warning, monitoring, reporting, suppression, command, and coordination can be fully connected. Even if forest fires cause damage to ground communication infrastructure, emergency networking can be quickly completed to ensure the stable transmission of core data such as command instructions, fire monitoring, and personnel positioning.

This communication system is equipped with a multi-path redundancy mechanism. When a node fails, data can automatically switch to other links, achieving zero communication interruption. It also has anti-interference capabilities, which can withstand the complex electromagnetic environment in the forest area and ensure communication efficiency and transmission accuracy. For the problem of communication barriers caused by rugged mountainous terrain and complex landforms, MESH broadband self-organizing network equipment can deeply adapt to complex scenarios and quickly build a collaborative communication command and dispatch system for multiple devices, enabling rapid response, efficient command, and precise dispatch in fire situation handling.

Industry Analysis

Demand Analysis

• Communication of on-site information is difficult to return. To effectively prevent disasters, it is necessary to understand the on-site situation immediately. Key information such as the overall situation, real-time video, personnel location, etc., must be clearly transmitted and available throughout the process. However, most emergency command equipment currently has significant shortcomings:

• The equipment is heavy and has poor portability, making it difficult to quickly deliver to the disaster front line and unable to achieve rapid activation, immediate use, and simple interconnection. This seriously slows down the emergency response efficiency.

• At the current emergency rescue site in the forest area, the emergency communication means are weak, and traditional radios are still the main communication method. Traditional radios have obvious limitations: in forest areas where public network coverage is insufficient or completely without signals, radios cannot support efficient communication among front-line personnel and lack stable wireless communication coverage, resulting in key information such as audio and video, on-site pictures, etc., from different operation areas being unable to be promptly summarized and unified back to the command center, causing information islands.

• The forest area is mostly remote areas, and there is generally no public network coverage. Especially in the event of a special disaster, existing communication facilities are prone to damage, forming communication blind spots, which leads to communication blockage between the front and rear command centers and delays in the transmission of instructions, inaccurate transmission of information, and inability to achieve joint decision-making and coordination. The lack of visual collaborative command means between the front and rear command centers makes it difficult to share on-site information, conduct joint analysis, and achieve efficient collaborative decision-making, affecting the scientificity and timeliness of fire situation handling.

Product Application Characteristics

• Remote communication: Based on the SDR software radio architecture and COFDM multi-carrier modulation technology, it realizes ultra-long-distance communication capabilities under line-of-sight conditions between air and ground. Single-hop line-of-sight transmission can reach over 100 kilometers, and multi-hop relay can cover larger operational areas.

• Domestic self-developed: The full chain is independently developed and self-adapted, building a complete technical system covering physical layer waveforms, core algorithms, and self-organizing network protocol stacks, suitable for different communication needs. Core chips and key components can be replaced with national products, and the software platform can be efficiently deployed on nationalized hardware architectures.

• Anti-interference algorithm: The product supports adaptive frequency selection, high-speed frequency hopping, etc. Through real-time spectrum perception and dynamic monitoring throughout the area, it adapts to complex and variable electromagnetic environments to achieve autonomous dynamic networking and precisely avoid frequency band interference; in strong electromagnetic interference environments, it can ensure normal communication and data transmission. • Mobile Communication: Capable of stable communication in high-speed mobile conditions. Through Doppler frequency shift compensation and rapid link switching, it ensures seamless connection between mobile nodes. Fully compatible with the rapid maneuvering and dynamic deployment requirements of unmanned platforms.
