目前車輛動態稱重信號采集系統存在體積大、集成度低等問題，PSoC(Programmable System on Chip)內部具有豐富的數字資源和模擬資源，本文主要介紹了基于具有全速USB接口的PSoC芯片 CY8C24794的車輛動態稱重信號采集系統的軟、硬件設計方法和實現。該系統小巧實用， 便于攜帶，節省了USB接口芯片、AD等功能芯片，與VXI高速采集系統采集的信號相比，本系統的實驗結果與VXI實驗結果類似，系統很好滿足了信號采集的要求。

　　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.
