摘  要:
A bivariable control system that combined GPS and GPRS was designed as the variable rate fertilizer embedded solutions,and the information platform based on ARM and DSP dual-CPU architecture was developed.Based on ARM9 and WinCE support the graphical user interface and touch operation,the host system was able to achieve information input and reflect the real-time operating status of the fertilization and seed production process.Based on DSP/BIOS real-time operating system,the slave system could implement the opening and revolution motor servo control of fertilizing and seeding.The system hardware and software structure,which has good scalability and real-time flexibility,was depicted in detail.The test results showed that the system could achieve fast and accurate fertilizing and seeding precision delivery.
