In today's complex and changing social environment, public safety faces unprecedented challenges. Whether it is natural disasters, emergencies or daily security maintenance, rapid response and efficient command are the key to protecting people's lives and property. As an emerging technical means, tethered relay system is gradually becoming an important tool in public safety management.1. Composition and working principle of tethered relay systemThe tethered relay system consists of three parts: drone, tethered power box, and tethered airborne module. Among them, the drone, as the main execution unit, relies on the continuous power support provided by the ground tethered power box to fly stably for a long time. At the same time, through optical fiber transmission technology, the drone can transmit the data collected by various payload equipment carried back to the ground control center in real time. In addition, the drone is also equipped with dual RTK (real-time dynamic) positioning function, which ensures centimeter-level precision position information, enhances wind resistance, improves flight safety, and ensures the success rate of long-term flight missions.2. Practical application needs in the field of public safetyIn the field of public safety, communication is the core of emergency response. However, at the scene of a disaster or emergency, conventional communication networks are often damaged, making command and dispatch difficult. Especially in areas with complex natural terrain such as mountains and forests, or in areas with dense high-rise buildings in cities, the problem of insufficient coverage of traditional base stations is more prominent. Therefore, a flexible, mobile and reliable communication solution is needed to fill this gap.3. Specific applications of tethered relay system in public safetyEnhance emergency communication capabilities: tethered drones can carry mobile, Unicom, Telecom 5G base stations or other types of relay communication equipment into the air and quickly establish temporary communication links. This is particularly important for rescue operations after natural disasters such as earthquakes and floods. It can help rescue teams obtain external support in a timely manner and improve rescue efficiency.Improve the effectiveness of police communications: For public security departments, tethered drones can be installed with special equipment such as public security telephones or self-organizing network radio stations to provide stable communication support for police officers. Especially in the process of large-scale event security or emergency handling, this aerial communication node can effectively alleviate the pressure on ground communications and ensure smooth and unimpeded transmission of instructions.Support firefighting operations: During the firefighting process, tethered drones can not only serve as high-altitude observation points to monitor the development of the fire in real time, but also act as mobile communication stations to ensure smooth information between front-line firefighters and the rear headquarters, facilitating scientific decision-making and resource allocation.Optimize traffic management: With the high-altitude perspective and powerful communication capabilities of tethered drones, traffic management departments can quickly deploy aerial monitoring points during peak hours or when major traffic accidents occur, collect road conditions information in real time, and issue warning information to surrounding vehicles through relay platforms to divert traffic flow.4. Advantages and characteristics of tethered relay systemLong-term endurance: Due to the use of ground power supply, tethered drones do not need to worry about battery power issues. In theory, they can achieve unlimited airborne operations, which greatly meets the needs of long-term emergency response.High-precision positioning: Tethered drones equipped with dual RTK positioning systems have excellent positioning accuracy and can maintain stable hovering even in strong winds to ensure that communication quality is not affected.High-speed data transmission: Using optical fiber for data transmission not only improves the data transmission rate, but also reduces the possibility of signal interference, so that the information collected by various sensors can be accurately transmitted to the command center.Multifunctional scalability: According to different application scenarios, users can choose suitable payload equipment to install on the drone, such as high-definition cameras, thermal imagers, gas detectors, etc., further broadening the application scope of the system.In summary, the tethered relay system has shown great potential and broad application prospects in the field of public safety with its unique design concept and technical advantages. Whether it is responding to natural disasters, handling emergencies or strengthening daily safety management, it can provide strong technical support for relevant departments. With the continuous advancement and improvement of technology, it is believed that tethered drones will play a greater role in more fields in the future and become one of the indispensable forces to protect social peace.
