Design of logistics transportation monitoring system based on GPS/DR combined positioning technology

摘要

At present, there are some problems in the research of logistics transportation monitoring, such as poor positioning accuracy, low actual loading rate and high cost. Therefore, a logistics transportation monitoring system based on GPS/DR integrated positioning technology is proposed. According to the actual needs of logistics transportation monitoring, the overall framework of the system is designed. The hardware of the system has the following functions: tracking, query, dispatching, monitoring centre, alarm of transportation tools and so on. The main process of the system operation is as follows: after receiving GPS/DR integrated positioning data, combined with other functional modules of the database, the transport status is displayed on the electronic map interface, and the positioning monitoring of logistics transportation is realised. The experimental results show that, compared with the current research results, the system has high positioning accuracy, high actual load rate, low transportation cost and high reliability.
