Design And Implementation Of Electronic Price Tag Management Systems Based On IoT

With the rapid development of China’s economy, the mall’s price tag to get everyone’s attention. In daily life, the price tag can be seen everywhere, it provides information on the name, origin and price of goods for consumers, easy to buy. But the traditional paper price tag in the process of production and use in the production conditions and vulnerable to external environmental factors, since the price tag that displays information and product information does not match the actual problem is not only brought trouble for consumers and even cause disputes between businesses and consumers. To address this problem, a price tag on things electronic management system to ensure accurate price tag information in real time to achieve comprehensive management information is displayed on the price tag and work status.As the national 863 project "Industrial control integration projects based on Internet of things" part of the system through the analysis of development present situation at home and abroad, combining the relevant technology of the Internet of things, the design and implement a set of complete electronic price management system. This system main work is as follows: (1) The existence of the traditional price tag easily lost, slow updates and other issues, is no longer using the traditional paper products and LCD screen as a display device, instead of using electronic paper display, this display with easy to read, low power consumption and no need to continue to refresh; (2) Price tag display terminal regularly send heartbeat packets and save heartbeat packets in database by checking the information of heartbeat packet of to achieve the price tag is displayed in real-time job status of the terminal management; (3) Using B/S model to build management system of electronic price, all price tags can be created, search, delete operation, such as export price tag information and print can be implemented at the same time; (4) Ensure the information in the database^ the interface display information and equipment information synchronous update; (5) Through the Socket asynchronous communication technology, the complete price display terminal of real-time communication and management system, which makes the sending and feedback of information receiving instructions simultaneously, to ensure the communication of the whole system is normal, to realize the management of the electronic price comprehensive and real-time.The system combines wireless networking transmission technology, Socket communication technology, the choice of low-power, high-performance hardware. And it has been tested show that the system running stable, can be transmitted at a distance information between the nodes, the price tag display terminal can interact with timely information and management systems. Meanwhile, the system has a low power, low cost, small size, easy installation, scalability, strong anti-interference ability and wide range of applications, to achieve effective management of the electronic price tag.
