Design And Implementation Of The Control System Of Automatic Says Feeder

Automatic says feeder replace artificially says materials, in production efficiency and product quality has made important progress on, as the electronic technology and sensor technology development, the automatic feeder system has been widely said the applied on concrete, feedstuff, medicine and health, mould processing, etc. However, different occasions, different weighing requirements, symmetric feeder requirement also have very big different, need according to the specific accuracy requirement and specific functions for the design of concrete. At present, the accuracy of the automatic batching machines ingredients, reliability and stability, safety and production efficiency become automatic says the focus of research feeder system.This paper mainly introduces a kind of mold processing powder feeder control system be automatic says. This paper first to weighing transducer output signal, and then design AD transform the automatic control say material control and automatic display hardware circuit, respectively for the Micro Luminary LM3S316 chip and MCU of the company STC12C5A chip. Have AD transform concluded signal light LM3S316 decoupling isolation into three road, and then control, one, four sensors to transmit information weighing corresponding show board the above control chip microcontroller, SCM SM1628 shows the weight signals through to the digital tube. Second, when in calibration or material value is set by the work, the buttons above display panel set each weighing values, SCM, LM3S316 value transferred to analyze and process of opening, operating decision motor and stop, so as to realize the control of material. Third, when system calibration material value set up, according to the finished, start work button, system began according to set good parameter auto start control of material, if the material end do not satisfy the products get weighing of software system error request, according to the error real-time computing revised the relevant parameters, algorithm until meet the system requirements position.This topic design realized the error, stability, subject speed and automatic control requirements, and achieve the expected purpose.
