Design Of Real-time Drive Embedded System For Infraredscene-array

Infrared guidance missile is a weapon with significant anti-jamming capability which has become a main way in the air-to-air combat technology development currently. The capability of missile testing is an important process in the research to save the time and the cost. As a core part of the missile performance evaluation,the array drive system can provide infrared scene for hardware-in-the-loop test platform to test the performance of missiles. How to improve real-time and drive capability is a hot problem in the present study,which contribute the important significance to the defenses of our country.Compared the advantages and disadvantages of three kinds of existing system,the paper designs a new the embedded array drive system for infrared scene which is aim to improve real-time and reliability capability. The paper also completes the hardware and software in the construction of the system and implements the array driver and the overall performance of the system of evaluation. The main work is listed as follows:Firstly, three exiting kinds of infrared scene array driven solutions are analyzed,on this basis, a new the embedded array drive system which has strong real time and high reliability is designed. According to analysis and research software and hardware performance and mechanism of hardware and software, the system is constructed and the real-time capability of each System unit is researched. Those works provide the necessary guarantee and guidance to complete software and hardware design of the system.Second, the overall of the embedded array drive system is planned, and each unit of hardware is analyzed and designed to form the system hardware framework, including Bus transmission unit MPC8315 treatment, the FPGA conversion unit, array units, which laid a foundation for the entire functionality of the system implementation.Then, the software of the embedded array drive system is designed including transplanting the Linux kernel in the MPC8315, on the basis, the Reflective Memory card driver and Enhanced Local Bus Controller driver is exploited to complete the signal communication between each unit. The application software development of each unit is designed completely. This part is the core to complete the embedded array drive system.Finally, the drive array system and test platform is built. The function of the drive system platform for embedded array is Validated and analyzed. Compared the existing system, the improvements of this system in each performance, mainly focused on the outstanding performance in real-time and driving performance is analyzed.
