Abstract—To improve the efficiency of the remote monitoring system for logistics transportation, we proposed a remote monitoring system based on wireless sensor network and GPRS communication. The system can collect in-formation from the wireless sensor network and transmit the information to the ZigBee interpreter. The monitoring system mainly includes the following parts: Car terminal, GPRS transmission network and monitoring center. Car terminal mainly consists by the Zigbee microcontroller and peripherals, wireless sensor nodes, RFID reader, GPRS wireless communication module composed of a mi-cro-wireless monitoring network. The information collected by the sensor communicates through the GPRS and the monitoring center on the network co-ordinator, sends the collected information to the monitoring center, and the monitoring center realizes the information of the logistics vehicle in real time. The system has high applicability, meets the design requirements in the real-time acquisition and information transmission of the information of the logistics transport vehicles and goods, and realizes the function of remote monitoring.

With the rapid development of information technology, the revolution of animal networking technology has been pushed forward. The logistics industry has become an important application field of Internet of things technology. The real-time and effective management of logistics and transportation information and the realization of remote monitoring become the new requirements of modern logistics technology development. This paper presents and designs a remote monitoring system for logis-tics vehicles. The system can monitor all kinds of related information of the logistics vehicle in real time. Through the wireless network, it is passed to the regulatory cen-ter. The intelligent monitoring of logistics information is realized, which ensures the effective operation of logistics vehicles. The remote monitoring of logistics vehicles can effectively and timely grasp the situation of logistics information, strengthen logistics management, improve logistics efficiency, and reduce unnecessary logistics costs.
2 State of art
At present, wireless sensor networks (WSN) have been widely used in the monitor-ing of logistics and transportation information. Wireless sensor networks are born with the rapid development and maturation of technologies such as integrated circuits, sensors, wireless communications, and microprocessors. It is the result of the devel-opment of information acquisition technology from simplification to miniaturization, networking and integration. Wireless sensor networks are used in many fields of lo-gistics industry, such as logistics, warehousing, environmental monitoring, dangerous goods logistics management, cold chain logistics management and so on [1-3].
The wireless sensor network based on ZigBee technology is used to collect the transporter information in the logistics transporter[4 -5]. Through the WSN network, the logistics information data is transmitted to the remote monitoring center. The transport vehicle is equipped with a movable sensor node for collecting information of the transporter and the goods[6-7]. Within the coverage of the network, infor-mation is transmitted to the monitoring center through routing nodes in the wireless sensor network [8-10].
3 System architecture
Monitoring system includes the following sections: car terminal, GPRS transmis-sion network and monitoring center. The structure is shown in Figure 1. Car terminal is actually a wireless sensor network, which is installed in the transporter. It can be divided into several sensor nodes and a network coordinator. Car terminal is a minia-ture wireless monitoring network. It is mainly composed of Zigbee MCU and periph-erals, wireless sensor nodes, RFID readers, GPRS wireless communication module. The sensor node is used to collect the label information of the goods on the car and monitor the driving information of the car, such as the temperature and humidity inside the car and the information of cargo safety. The tag information of the item is automatically recognized by the RFID reader installed on the collection node. The collected information is communicated to the monitoring center via GPRS on the network coordinator, and the collected information is sent to the monitoring center. According to the received information, the monitoring center grasps the information of the logistics vehicle in real time, and gives the control instructions to the transport vehicle, so as to realize the remote monitoring. The remote monitoring of transport vehicles mainly comes from the information collection, transmission and monitoring of wireless sensor networks. Therefore, this paper focuses on the hardware and soft-ware implementation of wireless sensor networks. Remote monitoring system struc-ture is shown in Figure 1.
