[Abstract]:Fuel is widely used in industrial and agricultural production and human life. With the development of science and technology, burners emerge as the times require in order to make the development and utilization of fuel more reasonable. Nowadays, the burner has gradually entered into various fields of human production and life, and combustion process control has become the main field of control theory application. Compared with other developed countries in Europe and America, the history of development of burner technology in China is relatively short and the technology is relatively backward. There is no clear quality and safety standard for the production of burners and combustion control equipment, and imported burners and control equipment are of exquisite workmanship. Efficient environmental protection, but the price is on the high side. In this paper, a low cost, intelligent, high efficiency and high safety gas burner control system is studied and designed in accordance with the EN298:2003 safety standard of EU and the actual demand of domestic combustion control system. The system realizes the one-key automatic operation of the gas burner by STC single chip microcomputer, and adds the intelligent control mechanism for the process of air intake, ignition and gas transmission during the operation of the equipment. At the same time, in order to ensure that the equipment is always in a safe working state, that is, the state of FailSafe and the hardware, double MCU technology and software are adopted, and a series of logic judgment based on safety are set up in the system for the functions of detection, control, reset, etc. It has the ability of locking and self-repairing. In order to make the product have higher reliability when it is put into production and use, and to improve the (EMC) capability of electromagnetic compatibility, the hardware circuit is carefully designed. The high voltage part of the circuit 220 V AC and the low voltage part of the power supply to MCU are all isolated by photocoupler. In addition, in order to protect the intellectual property rights and the rights and interests of the factory, the system has set up a self-written chip encryption program, so that illegal elements can not steal the program on the chip even if they copy the hardware part of the circuit board. In the later testing process of the system, the basic function of the system is tested by the test bench provided by the manufacturer. The results show that the system can intelligently control the air intake, ignition, gas transmission and other processes according to the predetermined process. And the simulated fault can be latched and repaired. The stability of the system is tested by using the DN801 electric fast pulse group electrostatic jammer. The results show that the system can work normally and stably under the condition of pulse group interference and meet the requirements of the gas burner control system. Finally, with the help of the project manager of the system manufacturer, the system integrity test is completed: all the system functions and technical indexes meet the industry standards and manufacturers' requirements, and have been put into mass production and put into the market.
