行動式車輛動態稱重灌置的開發與研究
摘 要：本文通過對車輛動態稱重的工作原理、理論基礎及特點的分析，設計出1套動態稱重系統並簡述其實現方法，包括硬體和軟體的設計。其功能是動態測量行駛中汽車的前後軸重，並計算其總重，判斷是否超載，實現全自動、不停車監測。
該系統採用分散式管理方式，主控機採用PC機，資料採集系統採用AT89C51為中央處理器的`微控制器系統，主控機與資料採集系統之間通訊聯絡採用RS-232序列口進行通訊。
系統軟體共分PC機與微控制器兩大塊，其中：微控制器部分軟體採用MCS-51組合語言編寫，PC部分採用Microsoft公司的 Microsoft Visual Basic 6.0應用程式開發工具設計。該系統既可以成為1個獨立的檢測單元來使用，也可以通過主控機的資料庫系統與整過檢測站乃至全國各汽車檢測站實現資源共享。

Develop and Research on Convenient Dynamic
Vehicle—Weighing—System on Highway
Abstract: This article gives a systematical study about the theory and methods of design automobile’s brake system. Design a set of dynamic state of weighs the system to combine simple description in fact now method, include the design of the hardware and software. Its function is a dynamic state to measure to drive the medium automobile in front and back the stalk is heavy, and compute it total and heavy, judge whether overload, realization fully automatic non—stop metering .
The system adopts distributive management, PC is used as the master-control, and data collection system adopts AT89C51 as the CPU of the SCM (Single-Chip Microcomputer). Using RS-232 to implement the communication between master-control and data collection system. In the system, the part of SCM is compiled with the language of MCS-51, and the software for master-control is compiled with the application tool, Microsoft Visual Basic 6.0 of Microsoft Company.
The system can be used as a separated test unit, also shared by the whole test station through the database in master-control, even by the entire country.
