Research And Development Of Emulsion-Pump Monitoring System

With the technical development of the production of colliery,the power demand of Emulsion Pump Station need to develop from senventy five kilowatt to two hundred fifty kilowatt. The company of wuxi colliery equipment and other company have produced Emulsion Pump Station that have three hundred fifteen kilowatt. With the the power increase of Emulsion Pump Station, the demand of safety work is in the face.With development of the industrial automation, the need on monitoring system of field application has been increased greatly, such as the real-time ability, reliability, stability, expansion ability, this monitoring system ,Under the control of S3C44B0X, sensors acquired data. After transaction in circuits, the data is sent to processor for analysis and processing. The data processed is displayed on the LCD display screen.using the keyboard to setting the parameters,after the analysis of the sensors acuiredata the monitoring system control the electromagnetism valve. When needed, alerting signal could be sent and the power of emulsion pump could be cut off. And will protect the Pump.this monitoring also can save the trouble records that had happened,and user can easily check the record and do more research. The monitoring control will come true.The thesis first analyses the demand of the system, confirms system function goals and required performance, then puts forward the designing overall frame and divides function modules. Then the emphasis is put on hardware design, software programming. It is discussed that the S3C44B0X and it's peripheral circuits, multichannel data acquisition circuit, LCD display screen circuit, keyboard circuit, save circuit design and the software design of these modules. Thereinto,the design of software is the the most important of this system,based on the function,the software mainly dived into fore parts,the first model is circle check,the second is the parameters setting ,the third model is history check,the forth model is time setting.Finally give some suggestions to further improve credibility of the system and web development and to make more beautiful display.the characteristic of this systerm is low power,powerful function,low cost,real-time ability,and easily control.this system assure the safe production of colliery...
