The Design Of Anti-aircraft Machine Gun Control Based On DSP Technology

Paper analyzes the significance of the research(remote- controlled arms for example),and through access to documents and materials at home and abroad to introduce the development of the domestic and foreign remote-controlled arms, and gives the opened technology Indicators of domestic and foreign remote-controlled arms . Because of the proposed improvements of our country is backward on remote-controlled arms, giving the advice of upgrading remote-controlled arms.And then to describe the basic constitutes,working prince- ples and working methods of the fire control system. And more detailed the process of the Guidance,Track,Shooting Table. And introduced some basic concepts of the shooting table, as well as introduced how to calculate it.To analyse the mathematical model of the gun's pitch axis,the speed of the circuit design,the track of the circuit.The similarity of azimuth and pitch axis brought great convenience to design. Speed loop is an important part of the servo control system. Speed loop use the correction algorithm of a high-speed square lead-lag, azimuth loop use the correction algorithm of first-order square advance-lag.In order to achieve all-digital servo system closed-loop control, the paper briefly introduced the servo motor, encoder, as well as the machine of Measuring speed, and other components of the principle of selection ,and to TI's TMS320F2812 produced as a controller, the design of the hardware circuitry to realize the azimuth -Axis, pitch-axis control, and gives the results of software design and flow chart.Some anti-aircraft machine gun for example, giving the test results of some anti-aircraft machine gun firing and analyzing several different ways of shooting under the point of impact and the current distribution system as a whole was also shortcomings, and propose to increase the percentage of hits.This fire control system can be applied to vehicles, or fixed position, which has already applied to a howitzers and a machine gun . According to initial idea of the designers , we hope one guide device which can be used to guide more than the controlled object in the future, and then by a central computer to guide the multiple guide devices, which determine in several guide devices whose accuracy is highest. So a large position may be operated only by a few people, and they are all in a secure bunker in. That is not only saved, but also To ensure the safety of the combatants and increase the accuracy of hitting the enemy, at the same time the combatants can fight against a lot of the enemy. It also envisaged to do a simulation exercise program. On the one hand the operator can easily learn how to use the device, the other aspects the operator can carry out simple maintenance of equipment.
