目前车辆动态称重信号采集系统存在体积大、集成度低等问题，PSoC(Programmable System on Chip)内部具有丰富的数字资源和模拟资源，本文主要介绍了基于具有全速USB接口的PSoC芯片 CY8C24794的车辆动态称重信号采集系统的软、硬件设计方法和实现。该系统小巧实用， 便于携带，节省了USB接口芯片、AD等功能芯片，与VXI高速采集系统采集的信号相比，本系统的实验结果与VXI实验结果类似，系统很好满足了信号采集的要求。
Abstract:
The vehicle dynamic weighing signal acquisition system exists bulky， low integration issues， PSoC (Programmable System on Chip) has a abundant of digital and analog resources， this article presented design of signal collection system for WIM based on PSoC chip CY8C24794 with a full-speed USB interface. The system is compact and practical， easy to carry， to save the USB interface chip， AD chip and so on， compared to the signal of high-speed acquisition system with VXI， the experimental results of this system is similar to the VXI system very well and it meets the requirements of the signal acquisition.
