The cumulative control of some mixed materials batching is realized by batching scale. This accurate cumulative control can cut down the cost of manufacture, improve the quality of the product and enhance the efficiency of labor.Automatic batching and weighing system is a kind of integrating transportation, measuring, mixing in an online automatic weighing apparatus measured dynamic. This system consists of one or more ingredients belt scales, can show not only transient flow and total amount of conveyor belt, can also according to the value of the instantaneous flow deviation to adjust to the size of the feed to flow, constitute a closer setting control system, and achieve constant flow of purpose. Along with the rapid development of industrial production, electronic belt scale increasing demand of burdening system, was widely applied in a pan of metallurgy, power, chemical industry, food industry etc of process control. At the same time, along with the puter technology and the rapid development of the automatic control technology, the system application technology more advanced, more extensive, field can take the scheme is more agile diversity, and, due to the system often costly, users of the actual conditions are also different. Therefore, careful, choose a reasonable, perfect, economic solution appears especially importantThe structures of the belt scales ingredients consists mainly of transmission mountings, weighing transducer speed sensor, scale, active roller, driven roller, conveyor belt conveyors, drag, adjusting devices, equipment etc. When the scattered in conveyor belt scale body through the material on the weighing scale body, the speed sensor and sensor signal and the weight of millivolt belt speed pulse signal through the junction box to strap balance meter.The overall design philosophy of the Automatic batching and weighing system of the belt is: Before the belt conveyer is put into operation, the settlement value of the flow of the supplies is established on the keyboard by the attenbant to carry on the belt. After the system is put into normal running, loading signal of the belt that the onechip puter samples and the speed signal leaves, walk belt speed signal and belt instantaneous weight, unit of length is it can calculate out belt twinkling of an eye flow F of supplies to multiply (t) . The flow can be in charge of the number and show, offer the craft data to attenbant to consult in the twinkling of an eye. 8031 systems and then pare the actual value of the flow instead of the establishing
