Research And Application Of Fluid Leakage Detection System

Fluid is the combination of liquid and gas.It is the crucial resource of people’s production and living.It plays a major role in the progress of the society as well as in the development of human civilization.Because the promotion of industry cannot live without gas and oil while the routine life of the citizens can not live without water and gas in the society.Meanwhile,it is a vital task for us to save and protect the fluid resource.Once the fluid leaks,without being discovered and dealt with in time,there will be a great amount of financial losses and resource waste.Moreover,it may cause irreversible damage to the environment.Therefore,it is urgent that the leakage of fluid should be tested and monitored.The design takes the test of fluid piping leakage as the object of study.The main research comes as the following: analyzing the fluid piping model,taking the steady piping as the chief analysis target,making Microcontrollers C8051F040 the principle Processing Unit,using temperature transducer DS18B20 and Pressure sensor CEMPX221 and turbine flow meter LWGY-C to collect data,then transferring the data to the host computer through the interface CAN/RS485 and the RF Wireless Data Communication Module XL02-232AP1,finally,the host computer will show the situation of each piping of every rank area with the Supervisory Control and Data Acquisition MCGS according to the calculation of the steady piping.The manifestations of the advantages of this design are the following: Firstly,the design is built on the theory analysis of the mathematical model.Secondly,comparatively overall data collection that includes temperature,pressure and flow has been done.Thirdly,both wired and wireless communications have been applied,which reflects the flexibility of the Microcontrollers.Finally,the current situation of the piping could be observed directly by the host computer with the Supervisory Control and Data Acquisition MCGS.
