自动称重配料系统是一种集输送、计量、配料于一体的在线测量动态自动衡器。该系统由一台或多台配料电子皮带秤组成，不仅能够显示瞬时流量和累计量，还可以根据输送带的瞬时流量与设定值的偏差去调整给料量的大小使瞬时流量更加接近设定值，构成一个环控制系统，达到恒定瞬时流量的目的。随着工业生产的迅速发展，电子皮带秤配料系统的需求量日益增大，被广一泛应用于冶金、建材、电力、化工、食品等行业的工艺控制。同时，随着电子计算机技术和自动控制技术的飞速发展，该系统所应用的技术更加先进，领域更加广泛，可以采取的方案更加灵活多样，而且，由于系统往往耗资巨大，用户的实际条件也各不相同。因此，慎重，全面地选择一套合理、完善、经济的方案就显得尤其重。

自动称重配料系统的结构组成主要由输送机架、称重传感器、测速传感器、秤架、主动滚筒、从动滚筒、输送带、张紧装置、拖动装置、调偏装置等组成。当散落在输送皮带机上的物料通过秤体时，秤体中的称重传感器和测速传感器分别把重量毫伏信号和带速脉冲信号通过接线盒送往皮带秤仪表

自动配料系统的总体设计思想为：皮带输送机投入运行前，输送皮带上物料流量的设定值由操作人员在键盘上设定。系统投入正常运行后，单片机采样皮带荷重信号和走速信号，将皮带走速信号与皮带单位长度上的瞬时重量相乘即可计算出皮带上物料的瞬间流量F(t)。瞬间流量可通过数码管显示出来，为操作人员提供工艺数据参考。8031系统再将流量实际值与其设定值进行比较，经PID调节运算后计算出控制量vi，再转换为电流输出信号h后而后经放大去控制可控硅的导通角，实现调节滑差电机电磁离合器励磁电流的功能，从而调节执行机构滑差电机的转速，使输送皮带上的物料流量尽可能稳定在设定值附近，并具有良好的静态指标和动态性能。

配料皮带秤的结构组成主要由输送机架、称重传感器、测速传感器、秤架、主动滚筒、从动滚筒、输送带、张紧装置、拖动装置、调偏装置等组成。当散落在输送皮带机上的物料通过秤体时，秤体中的称重传感器和测速传感器分别把重量毫伏信号和带速脉冲信号通过接线盒送往皮带秤仪表[3]

物料通过给料设备送至电子皮带秤，称体中的称量传感器和测速传感器将称重和速度信号送至称量仪表，称量仪表显示输送物料的瞬时流量，累计量等数据，同时，测量仪表跟据测量值与设定值的偏差，通过变频器去调整皮带秤驱动电机的转速，使之精确的以用户设定的给料流量给料，达到恒定物料瞬时流量的目的。

对于电子皮带秤，可选用刚质的S型称重传感器。其连接方式采用关节

轴承，处于受拉状态，其抗侧向力的能力强，可安装于封密的梁内，结构紧凑。该系统的特点是由一台上位机来控制多台给料机，为了实现一定的配比，各给料机之间的工作又是相互联系的，而且给定量要随当前的实际配比进行修改，因此其控制结构是较为复杂的。
