Automotive Electronics Value For Fault Diagnosis And Anti-cheating Device Development,

With the development and matureness of loading transducer, electronic truck scale has been widely used in many vehicle weight measurement fields, and become the main equipment. Economy and commerce has grown fast after China joined WTO, the trade turnover is more and more by use of electronic truck scale every walk of life, but there're some cheating phenomenons during the measurement. The most common cheating type is telecontrol cheating. So this dissertation is based on the cheating phenomenon and designs an anti-cheating and failure-detecting system.The research mainly concerns the work principle and structure of electronic truck scale, analyses the telecontrol cheating and the solution of anti-cheating. There are five parts in the dissertation, at first it discusses the whole thought of the design, introduces the system requirement of software and hardware design briefly, and also marks out the design approach detailedly. Then it introduces the design of front-end pass selection circuit, the design and realization of signal sample and signal process back-end. In chapter four we design the function of upper machine and also design the user interface by VC++. At last we introduce the setting manual and experiment result of the product.Our anti-cheating and failure-detecting system, can diagnose failure and give an alarm precisely, it has a good comment in PanGang group, we believe it's outlook would be well.
