     But the same people, life is also valuable, in order to protect the lives of firefighters to a greater extent safe, and improve fire fighting efficiency, related departments actively develop fire fighting equipment and systems, twenty-one centuries, a series of advanced equipment including bomb-type high-rise building dry powder fire-fighting vehicle, electromagnetic long-range fire-fighting gun, “Space guard”emergency escape mask, unmanned aerial vehicle fire-fighting system... are used in the rescue of fire. As for the Fire Suppression System of UAV, it contains a series of key technologies, such as integrated design, intelligent identification, accurate guidance, etc. . The Unmanned Aerial Vehicle (UAV) is one of the core equipments of the UAV fire-extinguishing system. As for drones, everyone is quite familiar with them. At present, they are widely used in aerial photography, patrol inspection and emergency rescue. They generally consist of a load-bearing platform, flight control system, power system, control equipment, aerial photo stabilizer, etc. , the flight control system mainly includes three parts: sensors, on-board computer and Servo action equipment. The functions of the flight control system include attitude stabilization and control, task equipment management and emergency control, the servo action equipment, which has been widely used in swing-type voice coil motor. 

     Swing Voice Coil Motor is one of the main products of Tongmao Electronics Co. , Ltd. , Kunshan. The swing angle and Torque of the motor can reach 120 degrees and 50 degrees respectively. M, is widely used in the semiconductor industry, automation, industry, aviation and aerospace industries.
