Abstract：A new method of multi-sensor measurement in sections based on kalman iflter and correlation analysis is proposed, aiming at the problems of poor measurement precision, poor reliability, and has manufactured a dynamic load measure board which can send wireless data. The main hardware design is using sTM32F103RB chip which is based on the cortex-M3 core as the core microprocessor which collect and pre-process parameters, and then use the wireless transmission module nRF24e1 to send pre-processed and original data to the Pc. software design is mainly the naturalization of theμC/OS-II real-time operating system on STM32F103RB, which contains data collection and process, wireless transceiver module. Finally, verify the reliability and accuracy of this system by testing a loaded car running regularitily on a simply supported beam.
