| Abstract: | Based on analyzing the scheme and technique of dynamic weighing of wheel loader, the aim of this study is to construct a test platform of dynamic weighing. After analyzing the hardware design requirement of the dynamic weighing system, the overall hardware design scheme is given, which is based on HMS30C7202 embedded ARM microprocessor and 24 bits sigma-delta A/D converter AD7730. And then all the hardware circuit sections are discussed in detail. Finally, large amount of field test experiments under critical industrial environment condition were carried out. Experiment results show that the system has high precision and good stability and its measurement error is within 1%, which indicates that the design of the test platform is successful. |
