压力传感器在升降式运输车称重系统中的应用

Application of pressure sensor in weighing system of lift platform carrier-vehicle

介绍了采用压力传感器来检测货物质量的方法，在阐述了压力传感器检测原理和框架车称重原理之后，根据现场测试数据进行了曲线拟合，并建立了称重的数学模型，提出了称重系统硬件和软件的具体实现方法。试验表明：在测量范围内，检测误差为0．6～0．8t，符合设计要求。

A method of goods mass tested using the pressure sensor is introduced. After expounding the detection principle of pressure sensor and the weighing principle of the carrier-vehicle,the curve fitting is done based on the site experimental data and the mathematic model of the weighing system is established. A spceific realization method of the hardware and solfware of the weighing system is proposed. Experiment shows that detection error is 0.6 - 0.8 t in the measurement range. This is in agreement with design requirement.
