Research on weighing technology of self-propelled modular transporters

为了进一步拓展自行式液压模块化运输车(SPMT)的应用范围,文章对SPMT的高精度称重技术进行了研究。通过在SPMT车板上布置重量传感器,并利用车辆的自身升降功能,实现了大型结构物称重和运输装船过程的整合。重点介绍了SPMT称重系统的技术原理及软硬件系统构成,并对系统误差和控制方法进行了分析,形成了完整的SPMT称重系统。试验证实,SPMT称重系统具有较高的称重精度,且可有效缩减称重工期、降低施工成本。

In order to further expand the application scope of self-propelled modular transporters(SPMT),this paper studies the high-precision weighing technology of SPMT.According to instal weight sensors on the SPMT and utilize the self-lifting function of the SPMT,it achieves the integration of weighing large structures and transport⁃ing them by ships.This paper focuses on introducing the technical principles and software and hardware system com⁃positions of the SPMT weighing system.It also analyzes the system error and control methods and forms a complete SPMT weighing system.The experiment proves that the SPMT weighing system has high weighing accuracy and can effectively reduce the weighing period and construction cost.
