【Abstract】 As the lack of online metering device for hydraulic excavator in the domestic, a dynamic weighing system of hydraulic excavator is presented in this paper. Firstly, the system is elaborated, including system function, working principle,accuracy control and the mathematical model of dynamic weighing system which uses Kane dynamic equation. Then data collection and design of hardware and software for data analysis is researched based on the ARM ATM32f103 and DSP TMS320F28335. With the combination of these two chips, the dynamic weighing system can process the data faster and the precision of measurement is higher. Portability and scalability of the system also become stronger. All above, the research here has a good market prospect and economic benefit.更多还原
