The Research Of Saving Energy Sources Controlling System About Burning Gas And Fuel In Kitchen

With the development of industrialization progress, the consumption of fossi fuel which is nonrenewable resources is increasing everyday. Although the human being have already faced the risk of fuel depletion, it is difficult to altert the reliance on the fossil fuel in the near future. However, we can make some effort to decrease the waste of fossil fuel. Nowadays, the catering industry and kitchen all use the burning oil or gas cooking stove with blower, but it is a waste that about 50%-60% accumulated time is vacant combuation during the course of every cooking. The purpose of the reaearch was to decrease the kind of waste.We mainly study the burning oil or gas cooking stove that is frequently used in restaurant. Adding a control system on the burning oil or gas cooking stove which can save the energy automaticly without alterting the operation habit of cook at the same time. In this study, we designed the hardware circuit of the whole system based on the signal-chip microcomputer(SCM) energy-saving and control system of ultrasonic wave . In the design, SCM was used as a control device and the content included the design of transmitter circuit, receiving circuit, power system, implementation circuit and temperature compensation circuit. In the section of software control, the study mainly used C51 programming language to control the entire system, and the system working principle is as follows: The SCM sends the pulse signal of 40 KHz amplified by power amplifier to driving ultrasonic wave sensor, and the probe receives echo, then forms the interruption signals through a series of of treating for the purpose of measuring the distance. From the distance to judge whether to implement energy-saving operation, and finally achieve the purpose of energy-saving by the pot down,the fire burning and the pot leaving, the fire extinction.The study also designed the gas control valve of the system after the design of the hardware and software control section of the entire system, and mainly designed the inside nomimal diameter and the body wall thickness of gas control valve. Finally, we did relevant experiments about measuring the distance using the ultrasonic wave after the hardware circuit of whole system was correctly welded, then the relevant data was obtained and experimental error was analyzed.
