Design And Implementation Of Information Collection On The Internet Of Things Based On Embedded System

In recent years Internet of Things (IOT) technology developed rapidly. Information acquisition is the foundation layer of the IOT system, and the information transfer through the cable or wireless network and the Internet, finally controlled and handled in various application platform. The desire of collecting objects and objects, objects and people, all the things and network is become true. Information collection is the foundation of collect all the things, so this paper is based on information acquisition, realizes a control system through the embedded system to manager information collection module, and realizes the data transmission through the wireless self-organized network, finally achieve a information acquisition system for Internet of Things.In order to achieve the information collection function of the IOT, this paper is based on Embedded-ARM system, develops a terminal node hardware platform that uses S3C2440as the core, and the hardware platform contains power supply module, processing and storage module, display and operation module, wireless communication module etc. Software platform uses Embedded Linux operating system, we transplant and produce bootloader, device drivers, the root file system, etc. On the platform of embedded system, we add GPS module, RJFID module, Barcode scanning module, temperature and humidity module as the main information collection module, to realize the basic function of information collection of the IOT. In perception level the system use GPS module, RFID module, bar code scanning module, temperature and humidity sensor as the main information collection module. At the network level use a2.4G wireless network card to compose a Adhoc network, to transfer the data with multi-hop; At the application level use the network management system, touch screen control module to realize the control and data processing, display work on various application environments.At the same time, in order to validate the performance and usability of the platform, this paper also set up a real network of information collect system, through the actual data acquisition, transmission, processing the performance of the system is demonstrated. The results show that the information acquisition system of the IOT can be effectively carried out all sorts of data information collection work, and terminal node has good mobility and portability, that is very suitable for information acquisition application in various special environment or emergency situation.
