Abstract
In order to improve the efficiency and stability of dynamic weighing and realize the on-board dynamic weighing of freight vehi-cles,a synchronous acquisition system based on strain sensors is designed.The Synchronous acquisition system consists of collector and communication protocol.The Collector uses STM8S003 microcontroller as the core and HX711 as A/D converter chip,and the RS485 as the communication interface.The collector hardware and software are designed,and the RS485 time-sharing communication program is proposed,and the test is carried out.关键词
