Intelligent proportioning and weighing control system and control method thereof

Abstract

The invention relates to the technical field of a proportioning system, in particular to an intelligent proportioning and weighing control system and a control method thereof. The system comprises a main control machine, an information collection module, a signal processing module and a control module, wherein the main control machine is used for setting formula parameters required by proportioning; the information collection module is used for detecting the weight of various raw materials in a material cabin, generating raw material information and sending the raw material information to a weighing instrument in real time; the signal processing module is respectively connected with the main control machine and the signal collection module, and is used for controlling the raw material weight according to the formula parameters and the raw material weight and generating a control signal; and the control module is connected with the signal processing module, and is used for converting the control signal into a discharging signal and conveying the raw materials into a material mixing machine to be mixed through a belt according to the discharging signal. The system and the method havethe advantages that the proportioning precision is high; the reliability is high; the proportioning intelligence is realized; the manual operation and control is not needed; and the production process requirements can be more precisely met.

Description

technical field [0001] The invention relates to the technical field of batching systems, in particular to an intelligent batching weighing control system and a control method thereof. Background technique [0002] The intelligent ingredient weighing system is a very important process in the production process of chemical, pharmaceutical and food industries. The quality of the ingredient process plays a decisive role in the quality of the finished product. The intelligent weighing and batching system is a multi-input and multi-output system. The conveying weight of various materials is set strictly in proportion, and the weight of materials is detected by instruments and sensors and adjusted in a timely and accurate manner. [0003] The automatic batching and weighing control system consists of an industrial computer with control software, a touch screen computer, and an electronic scale with a serial port to form a control network unit. It connects industrial computers, inst...

Problems solved by technology

[0004] However, at present, the degree of automation in the batching process of many enterprises is still not high, the software and hardware technologies used are backward, and some control points even rely on manual operation, which virtually restricts the development of enterprise technology

[0005] The current batching control system generally uses a metering bin in the metering process, and is equipped with a pressure-type or pull-type gravity sensor for power-electric conversion. After the signal is amplified by a secondary instrument, it is connected to PLC or DCS to complete the metering. The signal is in The process of transmission is easily disturbed, resulting in weighing errors

In addition, the on-site equipment such as silos and conveyor belts is relatively scattered, and the operation status signals connected to the main control room have long and numerous lines, which are prone to malfunction or line failure, and the troubleshooting is more complicated
