摘　　要：目前,在连续累计自动衡器中,通常使用速度传感器测量装置的运转速度。而这些衡器的工作环境一般都比较恶劣,速度传感器又极易被损坏,给生产带来很多不便,也造成了很大损失。基于双通道电子皮带秤的结构,利用数字信号处理理论中相关与卷积的方法,从理论上推导出了一个新算法,根据重量采样值直接计算装置的运转速度,为避免使用速度传感器奠定了理论基础。Speed sensor is usually used to measure the belt speed of the continuous totalizing automatic weighing instruments nowadays. But the working conditions of these weighers are very hard,and the speed sensor is extremely easy to be damaged. Based on the structure of dual-channel electronic belt weigher,and the use of digital signal processing theory,this article brings forward a new algorithm. Through analysis and comparison of the weighing signal sampled by the sensor,the belt speed is gotten,and it can be the base of avoiding using speed sensors.
