摘　　要：介绍了一种由石英晶体传感器和感应线圈构成的新型车辆动态称重仪。该系统克服了传统传感器随温度、时间的变化存在漂移、抗电磁干扰能力差、安装不方便,后期维护工作量大等问题的缺陷,为动态称重(WIM)设备技术提供了一种新的应用途径。In this paper, a vehicle weigh in motion instrument based on quartz piezoelectric and loop sensor is introduced. The designed system has a reasonable structure and no need of temperature compensate, overcomes the disadvantages of the tradition sensor in life time ,measure precision and maintenance, provides a new way to the weigh-in-motion facility.

关 键 词：石英晶体传感器 感应线圈 动态称重
