The Research Of The Internet Of Things Echnology In The Application Of Logistics Tray Positioning

The Internet of things is seen as a major development in the field of information and change, its wide application in the next few years to solve the line to make a great contribution to the generation of social problems.Since2009, the United States, the European Union and Japan have a IoT development plans, make relevant forward-looking layout, technology and industry in our country in the12th five-year plan will also be the Internet of things as a strategic emerging industries to focus on and promote.But as the microelectronic technology, computing technology, wireless communication and the development of low-power embedded technology, gives birth to the Internet of things technology, the wireless sensor technology is one of the important technology.Wireless Sensor network (Wireless Sensor Networks, WSN) is considered to be one of the most important technology of the21st century, it will have a huge impact for the future of the human way of life.In September1999, the United States by business week ranked wireless sensor network (WSN) in the21st century21one of the most important technology, which cause the extensive concern of the academic field.So far researchers entering the field, all areas of wireless sensor networks are getting more extensive research and faster developmentAt present the whole pallet load identification, generally uses the one-dimensional bar code.Identify content contains the pallet ID code, goods name, quantity of loading information, etc.Because of the information capacity is small, can’t said tray on the whole the detailed information of the items at the same time, for some large quantities of different kind of tray in warehouse planar chaotic put, not very good location, brought inconvenience to logistics process.Therefore, this article mainly by studying the RSSI ranging algorithm to determine the tray in the flat storage location problem.If the Internet of things technology in the radio frequency RFID tags technology, information capacity islarg, a scan can complete a large amount of information input, save manpower, which greatly improved the processing speed. And use the wireless sensor network technology, the information of radio frequency reading device to read tray, at any time will be read by the pallet information sent to the wireless receiver inside the shop, again through the cable network to upload information to the information management system, realize to warehouse tray positioning and scheduling management.
