Research and Design of Logistics Monitoring System

In view of the logistics tracking and monitoring, Zigbee technology, RFID technology, GPRS technology and GPS technology are combined in the system. Considering the actual demand of the logistics monitoring system, a logistics monitoring system is designed. In this paper, the principle and design of RFID monitoring node, video monitoring node, access control node and monitoring center are described. The system has been tested. Test results show that the functions and performance indicators meet the design requirements of the system. The logistics monitoring system has the advantages of good stability and convenient operation. It has good application prospects. Introduction With the development of society, the logistics industry has also been rapid development. On the one hand, in the course of transportation, the goods are damaged or lost often happen due to human factors or other factors. When the goods are damaged or lost, the reasons need to be found to provide a basis for claims. On the other hand, in the process of transportation, the monitoring center needs to understand and master the monitoring data of logistics vehicles. At present, the logistics monitoring system usually adopts GPS technology to monitor the location information of logistics vehicles. It uses RFID technology to monitor the goods. When the goods are damaged or lost, the reason for the damage or loss of the goods is difficult to be found. Zigbee technology is a short distance, low power consumption and low transmission rate of wireless communication technology. It has been widely used in the field of agricultural monitoring and intelligent monitoring system. RFID is a wireless communication technology. It can identify a specific target and read or write data through the radio. RFID technology has been widely used in access control systems, asset management and logistics monitoring. In this paper, a logistics monitoring system was studied and designed by combining Zigbee technology, RFID technology, GPRS technology and GPS technology. The system can monitor the goods accurately and timely. It can also carry out video surveillance of goods. System Principle and Hardware Design System Structure. The system consists of RFID monitoring node, access control node, video monitoring node, coordinators and monitoring center. The Zigbee wireless technology is used to build the network in the RFID monitoring node, the access control node, the video monitoring node and the coordinator. Nodes communicate with the coordinator through the Zigbee wireless network. Coordinator communicates with the monitoring center through the GPRS network. The system structure is shown in Fig. 1. RFID Monitoring Node Design. The RFID monitoring node consists of CC2350 chip, temperature sensor, humidity sensor, keyboard, RFID module and alarm circuit. Its hardware block diagram is shown in Fig. 2. The Zigbee technology is a kind of two-way wireless communication technology with high reliability. It supports star network structure, tree network structure and network structure. The RFID radio frequency identification technology is a non-contact automatic identification technology. It can identify a specific target and read or write data through the radio frequency signal. It has the advantage of easy to use, but the RFID is also insufficient. Active RFID has a far communication distance, but the cost is high. The cost of passive RFID is low, but the 6th International Conference on Management, Education, Information and Control (MEICI 2016) © 2016.

If the system can be combined with Zigbee technology and RFID technology, an efficient wireless sensor network system can be built. It uses RFID technology to identify the goods. It builds the network through Zigbee technology. In this paper, RFID technology and Zigbee technology are combined. It monitors the goods through the RFID module. The temperature and humidity in the logistics vehicle are monitored through temperature sensor and humidity sensor. Between the RFID monitoring node and coordinator, a Zigbee star network based on Zigbee technology is constructed. The monitoring data of logistics vehicle is stored in the memory. At the same time, the monitoring data is transmitted to the coordinator through the Zigbee wireless network. The RFID monitoring node is installed in the interior of the logistics vehicle. According to the needs of logistics vehicles, multiple RFID monitoring nodes can be installed. carriage Monitoring center base station GPRS network GPRS network Zigbee network satellite
