In order to improve the efficiency of grain food quantitative weighing, to reduce the labor intensity of workers and to improve the weighing accuracy, a control system of food quantitative weighing machine based on DSP was designed. The structure of granular food quantitative weighing machine was analyzed, and the quantitative weighing process was introduced. Based on the TMS320 F2812 DSP, the hardware structure of the control system was designed, and the control circuit of the motor driven by the DSP was designed. In order to improve the weighing accuracy of the weighing system, the sensor signal was amplified by the INA122 amplifier. The software of food quantitative weighing control system adopts modular design method, which realizes the simultaneous quantification of coarse materials and fine materials. It not only improved the weighing accuracy, but also improved the weighing efficiency. After field installation and debugging, the system could run stably and reliably.
