Research And Realization Of Single - Person Fire Control System Based On

Individual weapon equipped with fire control system can improve the precision of target. In order to improve the operational effectiveness of individual weapon, as to 40 mm shoulder-fired rocket system in this paper, the application of one-dimensional trajectory correction technology to remolding traditional individual weapons definitely improves the accuracy and reliability of the missile.Taking an on 40mm rocket as the research platform, this paper proposes an individual fire control scheme based on the one-dimensional trajectory correction algorithm utilizing GPS and digital signal processor, the study mainly consist of the following five aspects:(1)From the individual composition principle of fire control system, and analyses the function and performance requirements, using look-up table method and ballistic differential equation method of shooting because of the influence of the environmental parameters of the correction of firing data.(2)Through the calculation of projectile impact, ballistic model under the non-standard condition and its general forms are analyzed respectively. The superiority of Adams method to calculate the general form’s ballistic model under the variable step size is verified by the simulation results.(3)The TMS320F28335 chip of TI is selected as the intelligent terminal processor, the fire control system. From the point of the electromagnetic compatibility design to TPS767D301 power management systems, human-computer interface, memory module. power supply monitoring module and GPS and PC communication module.(4)To individual work process of the control system of fire control, the software of the system task division, and the design of each function or task program is introduced in detail.(5)The environment parameters’ acquisition function of the system is tested, as well as the positioning performance of GPS receiver, and the simulation of ballistic calculation of the firing data is carried out. The results verify the feasibility of the design of the individual soldier’s fire control system.
