The Development Of Boiler Intelligent Control System Of Embedded Microcontroller Unit

Recent years, the analysises and discussions about the provision and comption of energy in our contry has reached a unprecedented level. To economize on energy and reduce wastage is one of the most important ways to promote the development of the economy and to get more profit. At the present day, the rate of energy utilization is only 32% which is 10% lower that of developed contries. Facing so large amout of energ consumption, the demand of reforming traditioned gas-heading system brooks no delay. So in accordances with this situation, we pose a set of comprehensive plan to solve this problem: Intelligent controable system of boiler.In such kond of system, to set intelligent controllable terminals in every boiler room will achieve the goal of finishing related operation of the boiler automatically and in real-time. Such kind of controller regard 32it embedded microcontroller unit technology as the centrol part which would modify the operational condition independently and dynamically so as to finish the task of controlling of heat supply. As a result, it can icrease the efficiency of the system operation and redues the energy consumption effectively. Finally, it can reduce the interaction with the observing center of systematical operation.Has been again and again studied and argument, boiler intelligence the lord of the controller controls the LPC2294 hardware terrace of the unit adoption ARM7, on the plank peripherals with I2Cconnect for lord, plank the communication use the RS485 connect standard, total total line structure of the structure adoption distribute type to the spot equipments adoption master and servant-round the interview method for inquire.The boiler intelligence controller is according to the customer's enactment parameter and outdoors temperature, adopt the warm customer's indoor temperature etc. Then compute a chain stove row of headway speed and coal seam thickness, drum breeze quantity and lead amount of breeze etc. work parameter.Burn controller to pass to change the Pin machine control chain the stove row turn of electrical engineering soon after. On top of that, the controller is responsible for passing these parameters the spot total line to deliver boiler building a lord to control center of calculation on board, make the managing person clear to understand the movement circumstance of each boiler.Not only does this system heigten the quality of combustion, but also improve the fuel efficiency and the interval time of cleaning increases. As a result, the prime cost of boiler operation declines. The comprehensive fuel efficiency can increase as much as 15%~25%. Besides, during the period of operating and the changing of workload, the emission of NOx,CO and other kinds of solid grain stay in a low level.
