A Special Electronic Rf Modulator Design, Analysis And Experiments

In this thesis, modern control technology is tied in the Small Arms, by means of which an easy manipulated fire device was obtained. The firing frequency of the Small Arms can be decreased, at the same time, the precise of the fire can be improved markedly. The results of the paper have great significance to modernize the self-defensive weapon, enhance the design quality of automatic weapon as well.The control method for fire frequency of the traditional automatic weapon was further investigated, thus the new organization of a kind of control automatic weapon shooting tempo was designed, in which one-chip computer AT89C2051 to control opening/stopping and rotational speed of the electrical machinery were adopt, and then it was realized to the control hitting sports of the hammer. It can not only realize its function, but also improve its dependability to adopt a little components, while the button and arranging for the state alertlying light were assigned, its rationality and practicability were fully considered in order to make it operate and observe more convenient. First of all, the 3D model of the fire frequency adjuster was built. After that, on the basis of the choice of the right motor and the Micro Controller Unit, the circuit and PCB was designed. As a result, the fire frequency adjuster for Small Arms was built successfully. Both of the String firing and burst firing can be operated automatically. It is more automatic and smart than the similar device abroad.After the design completed, sufficient experiment was proceeded to the control system carried on the Small Arms. The result verify that the control system is able to decrease the firing frequency of the Small Arms...
