An Ingredient Analysis System Design Of Industrial Used Coal Based On S3C44BOX

The gangue is a kind of solid waste produced in coal mining and coal washing process. The emission of gangue in our country is large in amount every year; it not only takes up massive land resource, but also causes environmental pollution. To burn the mixture of coal and the gangue to generate electricity is the most effective way to solve the problem of pollution. Our country has made many preferential policies to encourage the enterprise, specially the Thermal power plant, to use coal and the gangue mixed fuel positively and effectively. Therefore analyzing the matching proportion of coal and gangue in the blended fuel in a fast and precise way plays a very vital role.This thesis first gives a thorough analysis to the design principle of the system, proposed the idea to use a single beam, and low energy ? ray transmission method to measure mixed fuel components, then introduced the design principle of the industrial used coal ingredient analysis instrument, which is based on S3C44B0X, and also introduced the ? ray energy signal gathering electric circuit; the quality signal gathering electric circuit of the blended fuel as well as the software and hardware design of the system in detail.The industrial used coal ingredient analysis instrument, based on S3C44B0X, is mainly composed by the ? ray energy signal gathering electric circuit, the quality signal gathering electric circuit of the blended fuel as well as the data processing system. The ? ray energy signal gathering electric circuit is used to filter, enlarge, reshape, and analyze the pulse signal outputted by NaI detector, and then a S3C44B0X counter is used to count. At the same time a precision electronic balance with a standard RS-232C serial port was used to simultaneously measure the quality of the signal of the mixed fuel. After the data processing system has processed and calculated the two input signal, the proportion of coal and gangue in the mixed-fuel is obtained, and real-time data is sent to the LCD screen for real-time data. This system also extends a network interface; the data can be transmitted to a remote PC, to prepare for later analysis. In software system design, this paper introducesμclinux operating system, in order to finish Blob boot loader and operating system migration. Precision Electronic Balance with S3C44B0X serial communications and data network transmission applications are focused on design.The system is easy to use. It can be equipped with the power plant and monitoring department of the laboratory to give a rapid quantitative analysis of the composition of coal in mixed fuel.
