| This project stems from a company's commission and the purpose is to adapt their products to market-oriented requests. The sponsor asked us to complete the system which technical target is parallel with the same manufacture abroad, and the same time reduce the cost of the machine. Therefore, making use of the integrate principle of mechanism, electronics, optics, liquid, researchers have designed a suit of feasible control scheme. Using the knowledge of mechanics and transducer, the water level induce part was developed to measure the water level signal in effect. The researchers designed the hardware part on the basic of the knowledge of electro circuit, the computer principle and the intelligent designing theory. Meanwhile on the aspect of software, a set of control demand. In addition, anti-jamming plan was also made to ensure the system stabilization and reliability. Consequently, if enterprises use this machine to pour their manufacture, cost of products will be decreased and their competitive capability will improved greatly. |
