Introduction
R&D Background China has entered a critical stage of economic and social development. With the accelerating social transformation, social disharmony and destabilizing factors have increased, and various types of mass incidents and emergencies have been increasing year by year. The social stability situation will be more acute and complicated. National separatist forces, religious extremist forces, and violent and terrorist forces are just around the corner under the support of hostile forces both at home and abroad. They are attempting to carry out separatist activities. The security situation in China still faces severe challenges. The task of maintaining national security and unity is still very arduous. The People's Armed Police Force fulfills its lofty mission of defending national security, safeguarding social stability, and ensuring that the people live and work in peace and contentment. It mainly performs duties such as on-duty, emergency handling, and anti-terrorism operations. Under the new situation, the armed police forces are faced with a qualitative change in the form of struggle, combat style, regional environment, and target structure. The requirements for the preparation of struggle are also increasing; they are suitable for policy, military, and legal. The demand for equipment in different areas of society is even more imminent, and it is imperative to research and develop equipment and troops to meet the needs of the armed police forces in the new era in their struggles such as on-duty, execution, and anti-terrorism. Tracking the development of non-lethal equipment in developed countries, we found that acoustic riot gear and technology are relatively mature and their use results are relatively satisfactory, representing the frontier of non-lethal anti-riot equipment that is more advanced internationally. In literature that has been published abroad, acoustic riot weapons are called remote acoustic devices - LRAD. Many western countries, especially the United States, have applied it in the military field and have used it to control riots and displace riots in their home countries, as well as in Afghanistan and Iraq. This has produced good results. In view of this, according to the needs of combat missions, a certain Chinese Armed Police unit has jointly researched and developed a "strongly dispel multi-function anti-riot vehicle" with complete independent intellectual property rights. On April 17, 2010, the car successfully passed the results appraisal organized by the National Acoustic Academy. [2]
Structural performance The vehicle is mainly composed of three parts: flood strike, media transmission, and vehicle-mounted maneuver. The repulse attack and the revenge attack are partially equipped with strong riot, tear gas launch, and high-light dizzy devices, and have remote shouting and repelling functions. The megaphone is a non-lethal, directed energy weapon equipment independently developed by China. It is a major breakthrough for China in the field of strong acoustic directional emission technology research. The system equipment of the louder is composed of a strong acoustic radiator array, an electromechanical control device and a rotary disk. A clear voice broadcast can be implemented within 3 km without any obstacles, and it can force the evacuation of terrorists and rioters who pose a threat 150 meters away. The array of strong acoustic radiators is a rectangular structure. Each array of transducer elements is distributed on a plane, vertically and horizontally and in parallel, forming a rectangular envelope. Through the phase control of the radiator array structure and the transmitted signal, the strong acoustic radiator array causes the sound waves to be reflected to superimpose in a specified place or direction and causes destructive interference at other positions, and thus propagates in a certain direction in the form of a beam. And change the direction of sound transmission as needed. The electromechanical control device of the electroacoustic device is composed of a gyro-supporting gimbal and an electric push rod and a corresponding controller, which mainly realizes the inclination of the acoustical device from horizontal to vertical and rotates around the rotational center. When in use, the horizontally vertical driving device is used to switch the horizontal sounder from a horizontal state to a vertical state, and the rotary disk rotates the sounder around the turning center through the motor. The horizontal vertical drive device consists of a drive motor, a worm gear reducer, a support shaft, and a support frame. The rotary disk is composed of a drive motor, a speed reducer, a rotary worm gear, a rotary disk and a base. In order to stop and reverse the disc, the drive shaft is equipped with an electromagnetic brake. The motor drives the rotary disk to rotate through the reducer and the worm wheel to realize the rotary motion of the sounder. When the horizontal rotation is vertical, the motor rotates through the reducer and the worm wheel to drive the rotation shaft, and the rotation shaft and the support frame are connected by keys and screws. [2] Media transmission The media transmission part is equipped with wireless image transmission, multimedia communication systems and lighting devices. It can realize non-line-of-sight and real-time transmission of information (video, audio, data, etc.) to the command vehicle or command center. In order to enable the commander to make timely judgments and decisions, and conduct effective command through voice communications. The mobile multimedia transmission system can perform real-time video image monitoring on the scene of emergencies under non-line-of-sight conditions, and can use HdMobile to establish a highly efficient, stable, and widely-reachable wireless mobile image surveillance transmission network through vehicle-mounted, piggy-backed, airborne, and shipboards. In various ways, the emergency scene image is transmitted to the corresponding commanding agencies such as the communications command vehicle and the urban emergency dispatch command center in real time through the wireless transmission link. The mobile multimedia communication system consists of HdMobile's core equipment - the central station and the remote station. The central station and the remote station can be in motion. Combined with other communication command vehicles, on-site image acquisition, display systems and other facilities, they constitute a complete burst. The live multimedia communication system has bi-directional and trans-horizontal transmission capabilities of data-voice-image under high-speed movement conditions. [2] There are two types of HdMobile devices, one is a backpacker and the other is a vehicle. In the wild environment, the individual soldiers carry HdMobile backpack-type terminal devices, perform tasks within 5 kilometers from the communications command vehicle, and transmit live images in real time. In the communication command vehicle, the HdMobile backpack center station device receives the images transmitted by the remote individual soldier, and can monitor the scene in real time and simultaneously perform remote command on individual soldiers. In addition, the on-board camera equipped with the command vehicle can also perform on-site image acquisition and transmit it to the rear command center in real time through the HdMobile mobile multimedia transmission system. At the same time, the HdMobile transmission system can also be used as a relay transmission device to transmit the image transmitted by the far-end individual soldier to the command center. On the large display screen of the command center, it can monitor and display the on-site images collected by the remote individual soldier or the communication command vehicle, realizing the remote real-time monitoring and command of the remote individual soldier and the communication command vehicle. Under the condition that the antenna height of the central station is greater than 60 meters, the most basic "point-to-point" communication mode can be used under a coverage distance of not less than 15 kilometers. The rear command center (or command vehicle) and the front information collection vehicle (or individual soldier) form a one-to-one communication system through the HdMobile equipment. The front information collection unit interacts the audio, video, and data with the rear command system to achieve The coordination and rapid decision-making between the various departments of the Party and the formation of unified command. [2] If the coverage of the entire target area is considered to be far beyond 15 kilometers, a multi-center station networking scheme will be adopted from the point of view of the settlement of mobile coverage. The entire mobile communication network will consist of several central stations, remote stations on board vehicles, etc. Several of the central stations will be selected at designated locations or locations with favorable geographical scope. Within the coverage of each central station, the vehicle-mounted remote station will complete wireless multimedia transmission and communication with the central station. The hard-switching completes the switching between the remote stations of the vehicle and different central stations. This networking solution solves the problem of network coverage of mobile multimedia transmission systems in large cities. The connection method between the central stations is usually 5.8G spread spectrum digital microwave and optical fiber and other two wireless and wired access methods. If there are available off-the-shelf fiber resources, then the main solution is wired solutions. The solution of the spread spectrum digital microwave will be used where there is no optical cable implementation condition to provide a reliable, carrier-grade device connection. [2] In addition, there are multiple remote station (one point multiple access) networking schemes and personal backpacking terminals combined with the vehicle remote station networking scheme. The former is the use of multiple vehicle-mounted remote stations to achieve multi-point, large-scale mobile communication needs. Multi-site communication can be provided between a central station and a 4-point vehicle remote station. At the central station, video segmentation technology is used to realize multi-point real-time monitoring and command. The latter is in the area where the communication command vehicle is not convenient to reach. The personal backpack type remote station and the vehicle-mounted remote station are used to realize the acquisition of on-site multimedia information, and the blind area covered by the system is better resolved. The entire mobile communications network will consist of three parts: a remote vehicle station, an individual piggyback remote station, and a central station. When the personal backpack type remote station works, the system terminal transmits field information to the vehicle-mounted remote station within the coverage area, and then the vehicle-mounted remote station serves as a relay station to transmit information to the rear command center; meanwhile, the vehicle-mounted remote station can also serve as a communication terminal station. Collect site information for transmission to the central station. In this way, through the entire emergency communications network, multimedia information such as images, voice, and data of a mobile multimedia transmission system can be collected and transmitted. [2] In- vehicle mobility The vehicle uses the "Warrior" off-road vehicle as a chassis, which enhances the timeliness and maneuverability of the equipment. The "strongly dispelling multi-purpose anti-riot vehicle" operation achieved a transformation from targeted strike to stereo attack, effectively supplemented the command means, and effectively expanded the combat style. The system will certainly play an important role in the armed police force’s operations on duty, handling sudden incidents, and countering terrorism. [2]
