Research On The Laboratory Management System Based On Internet Of Things

The internet of things realizes automatic identification and data information sharing of the target object through RFID technology, internet and wireless network to link between every person and every object whenever and wherever possible. At this stage because of the existence of cost, technology, policy, user barriers and other bottlenecks, the application still need times. This paper is an actively trying of the laboratory management system based on an internet of things technology.The system consists of RFID tag, reader, ZigBee wireless transmission nodes and host computer. The data information is stored in RFID tag and read by the RFID reader, then it is transmitted through the ZigBee wireless transmission nodes to the host computer, the information data of the label is processed by the host computer. The microprocessor STC89C52RC of radio frequency identification system receive the control command through the serial port to control the communication between MF RF chip RC500and the radio frequency card and complete the controlling of RFID card and RFID reader; RFID chips completes wireless signal coding and decoding, modulation and demodulation; RFID reader and RFID card communicates through radio frequency field. Wireless transmission nodes selects TI CC2430, this chip needs only few peripheral parts to realize signal sending and receiving function.The system researches the designing of the software and hardware of the laboratory management system based on ZigBee technology and radio frequency identification technology, and prospects the development and future at College.
