The Design Of Positioning, Collection And Transmission System Based On ARM

Recent years, the Internet of things technology rapidly appeared in people’s life inall over the world. The Internet of things is through the information sensing devices, inaccordance with the contract agreement, connecting all kinds of goods and internet, inorder to realize intelligent identification, location, tracking and detection, andmanagement of the network. Internet of things can be divided into three levels: theperception layer, network layer and interconnect layer. The perception layer isachieved by sensing devices such as sensors,RFID,two-dimensional code,positioning,multimedia and other information collection and items.In the current relatively popularin the Internet of things technology study, bar code technology and radio frequencytechnology represents the current mainstream recognition technology and the mostpromising technology in the future. With the development of civil navigation,GPStechnology more and more deeply into people’s lives. With the development ofcomputer technology, embedded technology is also a hot spot of today’s society,embedded ARM technology combined with the application of the Linux operatingsystem also has a great market value.This paper combined things of technology and embedded technology, proposed asystem based on embedded ARM platform, barcode recognition technology, usingGPS positioning technology and GPRS technology. Transplant linux operating systemon the arm platform and used the GPS module for locating information, and used barcode module for scaning the barcode, the last GPRS module transmits the informationcollected to the Internet.This paper first described the background and development trends of the Internet ofThings,the overall design and design process, pointing out that the key technologiesused in the system, and pointed out the hardware and software of system selection.Then carried out a detailed analysis of the embedded system development process.Again do a detailed description of the system’s hardware platform, including theminimum system design, the barcode module design, GPS and GPRS module design,circuit design and hardware modules made. Introduced the system software platform,linux software environment to build, driver development and linux applicationdevelopment. Make a final summary of the full text, pointing out the deficiencies in thesystem and make an outlook.
