With the development of science and technology, the development of automobile safety technology, especially tire safety technology is more rapid, the market application is gradually expanding. Therefore, the study of the new car stopping technology has important practical significance to improve the success rate of handling emergencies, and it has an important role to improve the capture of the suspect.1. technical analysis of existing car block equipment( 1 ) eight - type car stoppingThe eight - nine - type car arrester is the main vehicle which is often used. The car - stop nail is a kind of standard equipment to intercept or stop the motor vehicles of various pneumatic tyres by means of acupuncture and exhaust. It can be used in a variety of predetermined road, the size of goods vehicles, various cars, motorcycles, such as the lack of access or suspension, is the implementation of the task of blocking crossings, to capture criminals, rescue hostages more practical equipment.( 2 ) portable road block potaiqiThe portable barrier potaiqi is also the use of acupuncture exhaust method to destroy the tires to achieve the car. It is different from the eight - and - nine - type car arresterDifferent from the contact zone, its contact zone is made up of a number of interlocking aluminum strips. The aluminum bar is connected by a movable hinge and constitutes a telescopic shape. The structure of the car stop nail is basically the same as that of the eight. The improvement of the potaiqi is that it is convenient and convenient. When used, place the potaiqi and secure it on the side of the road, open the lid, pull directly out the car stop nail, spread on the predetermined road surface, and fix it on the other side of the road. Retraction shall be conducted in reverse order.( 3 ) remote controlled retarderThe remote control car car nail is generally composed of the remote control, the car car nail box two parts, its various types, relatively convenient to use. Automatic control of automatic layout, withdrawal and car nails is realized. Its principle is also the use of acupuncture exhaust method. The car arrester ( roadblock potaiqi ) introduced above is consistent in principle, that is, the acupuncture exhaust method: when the vehicle passes through the car stop, the car stops quickly into the tire under the action of gravity of the vehicle, and the high pressure gas inside the tire is discharged through the gas chute. At the same time, with the movement inertia of the vehicle and the elastic pressure of the rubber tire itself, the car arrester was pulled out from the base of the car arrester and took off with the tire, and continue to play the exhaust role until the end, so as to force the vehicle to stop driving. The above approach to the tire has inherent defects, such as in use, it is found that the vehicle can still taxi about 50 meters to stop, and easy to cause rollover accidents, adverse to the implementation of the task.( 4 ) car retarder networkThe hang about network, including the cord pull woven by special materials, is fixed to the ci on the net body. The intersection of a pull rope constitutes a node, and the ci nail is fixed to the network at least one node. According to this arrangement, the plurality of ci pins can be arranged on the same net body, when the tyre of the motor vehicle is in contact with the hang about network, the efficiency of the puncture nail punctured the motor vehicle tyre greatly increases; The hang about can also follow the wheel of the wheel to the axle of the motor vehicle, causing the wheel of the motor vehicle to not turn, forcing the vehicle to stop.Similar to the principle of hang about, x - net ( x - net ) is a strong viscous blocking network, winding the vehicle system, forcing the vehicle to stop. The product is light weight, easy to use, but the disadvantage is that it cannot be used repeatedly, so the use cost is very high. ( 5 ) rigid interception system ( rigid interception barriers ) these types of rigid interception systems are mostly driven by hydraulic rams to lift the rigid interceptor, and the control mode has manual, remote control and so on. This type of interception can effectively intercept illegal traffic vehicles. Companies such as secure Inc., Inc., Inc., Inc., Inc., Inc., Inc., Inc., Inc., Inc., Inc., Inc., Inc., Inc., Israel, Inc., are the most famous. Although the rigid interceptor can effectively intercept vehicles, but the rigid interception system has shortcomings, mainly:( 1 ) there is a possibility of lethal injury to the vehicle and crew, and there is no guarantee for the safety of life and property; the interception system is basically not reusable, and the use of high cost; because of the structural restriction, the two-way interception can not be carried out, the reverse vehicle can be passed through the slope; it is very high requirement for the defending terrain, because the intercepting device is rigid, the installation of the ground is very flat when the defense is deployed, otherwise it will cause the structural deformation of the intercepting system and affect the normal work. When using the box-type underground installation method, the construction is very difficult; the maintenance width adjustment difficulty, using rigid interception device, its interception width can hardly be adjusted, so the whole interception system is difficult to standardize, increase the cost of manufacturing and deployment.3. new research on the stopping technology of car stoppingIn recent years, the new car stopping technology mainly has the following several.( 1 ) the United States army of the United States army proposed the concept of microwave disabled vehicle electronic system in 1997, and carried out the test, but did not solve the problem of miniaturization. With the technological progress, the United States eureka aviationThe technology company studied a small car microwave remote vehicle interception system. The system is composed of power supply, oscillator and antenna, weighing 100 kg, microwave frequency is 350 MHz to 1350 MHz, stopThe cut-off distance can be up to 50 m. The system uses the DC as the output power of the automobile generator as the power supply, the peak output power is 2gw, and the energy output can reach 100j, the energy output can be up to 640, and these pulses can be amplified to 640 kv, and then converted to microwave by an oscillator composed of a pair of coupling transmission lines and some spark gap switches. finally, a specially designed antenna will point microwave energy beam to the fleeing vehicle, microwave energy will disturb or destroy the electronic system of escape vehicle, especially for the vehicle point fire controlThe electronic control unit ( ECU ) of the important engine function such as system, fuel injector, fuel pump control, let it short circuit, so that the engine will not shut off.Because the automobile engine produced in recent 10 years is controlled by integrated circuit, this kind of wireless remote control device plays an important role in most cars. Currently, the United States police are considering outfitting all police cars. The system operates around the clock, completely unaffected by the weather conditions and has no side effects on the human body. Eureka airlines is working to improve the interception system and make it more compact so that it can be placed in police cars, coastal patrol boats or helicopters.( 2 ) chemical retarderAt present, the chemical car arrester mainly is engine flameout agent, super, super corrosive, super agent several. Engine remove from heat agent. Enter the engine and gasoline ( diesel fuel ) through the air inlet to solidify, reduce the burning rate or not burn, and stop the power of the motor vehicle. The weapons made from remove from heat are mainly flame retardant and deflagration bombs. Flame retardant projectile. The flame retardant projectile contains some kind of choking gas, or a chemical that can rapidly expand into foam in the air. After hitting the target, either produce a gas that causes the engine to choke or generate a lot of foam near the engine, impede the cylinder piston movement, cause the engine surge , cause the engine to stall, and the life of the personnel is not dangerous, but can not be executed againCombat mission. Explosive projectile. It is a Fei ammunition that can cause the vehicle engine heart failure and cannot do work. The typical deflagration bomb developed and developed is the typical acetylene bomb. The elastic body of acetylene projectile is divided into two parts. Another part of the Assemble. The projectile explodes into the rear of the vehicle, and the water and calcium carbide react quickly to produce a large amount of acetylene and mix with the air to form an explosive mixture. After the mixture is sucked into the cylinder by the vehicle engine, a mass of deflagration or detonation is formed under high pressure to destroy and extinguish the engineFire, the vehicle broke down.Super lubricant. Some substances, such as PTFE and its derivatives, spray asphalt, concrete, grass and other roads to make the road surface almost without friction coefficient, as in the ice. Militarily, aircraft, missiles, artillery shells, bombs, and other vehicles can be cast to the airport, railway, highway, to make the enemy planes, trains, carsBec
