[Abstract]:With the rapid development of Internet of things technology and the continuous expansion of supermarket scale, people put forward higher requirements for the traditional shopping methods, and pursue an intelligent and convenient way of human-computer interaction. As a result, the concept of intelligent shopping guide emerges as the times require. The original intention of this paper is to solve all kinds of inconvenience encountered by people when shopping in supermarkets, to help customers understand the information of promotional goods in supermarkets, and to find the goods they want to buy more quickly and conveniently. Based on this, this paper combines ZigBee wireless communication technology with ARM technology effectively, and designs a supermarket intelligent shopping guide system based on ZigBee and ARM9 embedded processor. The purchase guide system adopts modular design scheme, which makes full use of the characteristics of ZigBee short distance transmission, low power consumption, low hardware cost, strong anti-interference ability and so on. The system takes CC2430/CC2431 as the module of ZigBee wireless sensor network, and then establishes the network system of ZigBee wireless positioning, which builds the network environment for the subsequent function realization. On the other hand, it makes full use of the high efficiency and fast performance of ARM9, and makes use of Linux to compile a visual friendly interface, so that the intelligent purchase guide system can be more widely used in various places to achieve the goal of low cost, high efficiency and strong practicability. In this system, UP-NETARM2410-S (S3C2410 processor) classical embedded experimental platform is used as the underlying hardware, and embedded Linux operating system is used as the software platform to complete the construction of the embedded system platform. At the same time, the SQlite embedded database is ported on this embedded platform, and the graphical interface of QT human-computer interaction is designed by C programming, and the effective combination of QT graphical interface and SQlite database is completed. Finally, S3C2410 is connected with the coordinator in ZigBee network through serial port, so that the data of ZigBee can be transmitted to the processor through serial port. By combining software and hardware, electronic map and commodity information are presented through touch screen, and finally the functions of commodity Zigbee location recognition, commodity query and introduction are realized. After testing, the system runs well and achieves the expected goal of the experimental stage. The positioning error of the goods in the target area is about 2 鈮
