⑨硕士学位论文 MASTER’S THESIS Abstract Wi也the rapid economic developmem and therising levelsofindustrialization,the natural environment hasbeen severely thegovernment has began to pay more andmore attention to theenvironment protection,OUr environment monitoring system isrelatively backward,which ismainly based on artificialacquisition and themonitoring locatiom are scattered,it is inconvenient to u曲the datamanagement,ff the datais collected through ,it would be inefficient ifthe dataiscollectedthrough wire,which requires transportation wire and consumes the above problems,anenvironmentmonitoring system based on GPRS andARM isresearched andimplemented inthispaper. Firstly,thetheory oftheGPRS technology andARM technology are studiedin this paper,the functional requirements ofthemonitoring system arc analyzed,then the overall structure ofthesystem isdesigned,prises threeparts:monimr,work and monitoring monitor USgS LPC2220 as its control C0re which isa舢7 microcontroller,∞nsors collect the data ofS02。 temperature andhumidity,then the GPRS module Uxmfers thesedam according the GPRS tothemonitoring center software which ison也e hardware is designed,including main control circuit,munication circuit and voltage transfermodule circuit.Ⅵ恤:t’S more,the anti—imerference about the hardware iseomidered. Secondly,the debug environment ofembedded system isbuiltin thispaper,pC/OS- II is1zansplanted into the ARM development platform,the drive ofevery hardware is designed,and theapplicationprogram isdividedinto 6tasks,the filteringalgorithm is ’usedtodealwith theenvironmentdata,themonitoring centersoRware isdesigned based on飘rmSock andMySQL databasetechnology,which hasthefunctionofreal-time data view,historical dataquery,chart analysis and print Ctc. Finally,the field test results show thatthesystem can achieve thepurpose of wirelesstransmission,real-time and continuou
