Description
Technical Field
The invention belongs to the technical field of antitank intelligent mines, and particularly relates to an anti-wind type supporting leg mechanism suitable for field layout of an intelligent mine weapon system.
Background
Land mines have played an important role in a number of war operations in history. As in the second world war of world war, 4.4% of people in the united states and 33% of vehicles are caused by mine damage; in the war, the number of the components reaches 10% and 56% respectively; in the case of the war, the number of lesions increased to 33% and 77%, respectively. In the 80 s of the twentieth century, with the rapid development of microelectronic technology, novel warhead technology, land mines which can be deployed and the like, land mines are changed from static and passive defense into weapons which can be rapidly deployed and flexibly used and can be counterbalanced with modern mechanical armies. Particularly, the intelligent mines which are developed in succession in the western military kingdom and can autonomously detect, actively attack, accurately strike targets such as armors and the like are developed, so that the mines are changed and expanded in quality from concept, principle, performance to combat mode.
The intelligent antitank mine is a novel autonomous defensive weapon which utilizes high and new technologies such as acoustic and earthquake waves, a microwave detection locator, a millimeter wave/laser sensor to detonate ammunition, a computer, information, microelectronics, dynamics and the like to integrate into a whole and can detect and destroy targets such as armor and the like within a certain distance range. The device can automatically search targets such as a tank and an armored vehicle in a certain range, detect the azimuth and the distance of the targets, carry out firepower decision through a ground command controller, drive a transmitter to rotate to a transmitting position by a servo mechanism, transmit sub-ammunition to the upper air of the targets, scan and identify the targets by a sensor, and detonate a warhead above the targets to attack the top armor of the tank vehicle, thereby realizing accurate striking. An intelligent mine can play a role in blocking hundreds of traditional mines, has wide defense range and high damage rate, and has remarkable military benefit.
The foreign intelligent mines adopt sound sensors and vibration sensors to detect targets, when the sound sensors and the vibration sensors detect noise and vibration generated when a tank armored vehicle runs, a control system starts to identify the targets, the initial positions of the targets are calculated and automatically tracked, and when the targets travel to the attack range, attack ammunition is launched to destroy the targets. The most representative are the M93 wide area mines in the united states, the "MAZAC" anti-armored mines in france, the ADW smart mines in germany, and the "speed-30" attack top-armored smart mines in russia, etc.
The intelligent mines developed abroad at present adopt acoustic and vibration sensor combined mode type detection targets, and the phenomenon of inaccurate target detection or misjudgment often occurs. To overcome these defects, the intelligent mine developed in China consists of a control mine and attack Lei Liangda subsystem, and each combat unit consists of a control mine and an attack Lei Liangda subsystemAnd the attack mines are formed. The control mine is a control command center of the intelligent mine, adopts three sensor combination modes of sound, vibration and radar to pre-warn, identify, position and track an armored target, and a computer control system judges and decides the received information and timely sends out an attack instruction for the most favorable attack mine, and the attack mine emits ammunition attack target after receiving the instruction. Once inaccurate decisions are generated during service, attack mines can be disabled and even misemitted. Among three sensors, acoustic, seismic and radar, radar plays a decisive role in target positioning and tracking.
