| This issue is an important part of National Key Laboratory of Transient Physics's project, which mainly aims to carry out research and development for TV-guided rockets.In order to launch TV-guided rockets,it is necessary to develop the launch-control device,which is in turns to make pre-launch preparations,detect the state and conduct the launch process.As the performance of embedded systems is improving,their application areas are expanding.The application of embedded systems in rocket's launch-control device can effectively manage communication between various modules,and achieve human-computer interaction and management procedures of the launch process.This device adopts embedded system design,with the use of S3C2410A chip in processor,whose architecture based on the ARM9,and the employment of embedded Linux in operating system and Qt/Embedded in GUI software.The design of the software employs the Host/Target development model.After establishing cross-compiler tool chain,BootLoaderⅥⅥ,Linux kernel,YAFFS file system and embedded database SQLite are transplanted to the processor,and then build GDB-Server remote debuging environment.Based on the previous work,serial communication program and SPI communication program design are completed,and the relevant drivers are programmed.Finally,the use of Qt/Embedded is to develop a friendly man-machine interface which basically realizes the function of the seeker inspection,the control cabinet inspection, linked inspection,process control and launch history of the inquiry. |
