Research And Development Of Commercial Kitchenware Energy Saving Automatic Control System

The extensive use of oil, coal and other non-renewable sources of energy, and the new energy development are unable to meet the widespread use and trigger a series of the energy crisis. Most of the large kitchen ware now is more use of manual control, low efficiency, a serious waste of gas. In order to solve kitchenware system wasted energy issue and the realization of kitchenware intelligent measurement and control system, the development of a kitchenware automatic energy-saving control system is necessary. Colligate practice, dependability, economic and other reasons.The use of SCM for the development of embedded processor system is the perfect solution.The system take AT89C51 as controlling core and the sensors (ultrasonic sensor,temperature sensor) as measuring component and the electromagnetic valve and the relaies as executive unit. First transform the distance signal measured by the ultrasonic wave,ambient temperature signal and etc into standard industrial electric signal. AT89C51 automaticly deals to data from the sensors, display information and accomplish warning instruction and control preventing according to the electric signal.The thesis first describe the monitoring demand of the energy conservation kitchenware control system, confirms system function goals and performance parameters, and then puts forward the designing overall frame and dividing into function modules. The hardware design, software programming and disturbing catalogue have been described. It is discussed the AT89C51 and the designs of peripheral circuits, multichannel data sampling circuit, LED display screen circuit, keyboard control circuit, data save circuit, time control circuit, electronic ignition circuit and ultrasonic ranging circuit and so on. The design of software is the the most important of this system Based on the function goal, the software mainly has some parts about connection software realization and monitor routine. It is verified by scene test that commercial kitchenware automatic energy conservation control system has low power, powerful function, low cost, real-time ability, and easily interactive control and may be put into practical use in future.
