Embodiment Construction

[0012] Such as figure 1 As shown, an intelligent batching automatic control system includes a hopper 1, a motor 2, a feeder 3, a weighing hopper 4, a weighing sensor 5 and a weighing instrument 6, and the weighing sensor 5 is located at the bottom of the weighing hopper 4, The weighing instrument 6 is provided with a weight setting module 61 , the feeder 3 is driven by the motor 2 , and the start of the motor 2 is controlled by the weight setting module 61 .

[0013] The weighing instrument 6 is also equipped with a fuzzy self-adaptive controller 62. The quality of the fuzzy control depends on the selection of the fuzzy self-adaptive controller and the establishment of fuzzy rules. This system adopts the model of double input and single output. The deviation e and the deviation change rate ec are used as the input variables of the fuzzy adaptive controller, and the output frequency u of the frequency converter is used as the output variable. For its specific control process, ...

Abstract

An intelligent automatic dosing control system comprises a hopper, a motor, a feeder, a weighing hopper, a weighing sensor, a weighing meter and a fuzzy self-adaption controller. The fuzzy self-adaption controller comprises a performance measurement unit, a control quantity correction unit and a control rule correction unit, wherein the performance measurement unit is used for comparing an actually-measured weight Sad transmitted by the weighing sensor with a set weight Wf of a weight set module and computing a deviation e between Sad and Wf and a deviation change rate ec; the control quantity correction unit is used for converting the deviation e and the deviation change rate ec into a correction value of the control quantity; and the control rule correction unit is used for converting the correction value into output frequency u according to a fuzzy composition inference rule and enabling the output frequency u to serve as the stop feeding initial lead epsilon to control operation of the motor. The intelligent automatic dosing control system performs fuzzy self-adaption compensation control of fall by means of a large number of existing weighing data so that material errors are guaranteed to fluctuate within the minimum range, and the intelligent automatic dosing control system has the advantages of high dosing precision and the like.

Description

Technical field: [0001] The invention relates to a batching system, in particular to an intelligent batching automatic control system. Background technique: [0002] The existing batching system stops feeding when the weight of the material in the weighing hopper reaches the set value of the weighing instrument. When the feeding motor stops feeding, some materials will fall freely in the air. Into the weighing hopper, these remaining materials are called drop. Due to the impact of drop, the set value of the material weight should be the standard weight of the material to be prepared minus the drop value. Different raw materials have different specific gravity and fluidity. The level of the material in the silo will cause uneven force on the material, and the unpredictability of the increasing material level in the hopper with the increase of material. Speed ​​and so on, will make the drop in the air change. In addition, the hysteresis of the hopper, the response speed of ...
