Research And Implementation Of Transportation Monitoring System Based On Internet Of Things

Transportation is an important tool to regulate and controll the market resources, also an important pillar of promoting the development of the national economic. With the continuous development of the transportation industry and the diversity of the transportation goods, the demand of monitoring transport is also increasing. The existing transportation monitoring system is difficult to achieve the real-time monitoring and safety management of transport goods, which greatly affect the safety of transportation.To solve above problems, this paper combines with Internet of Things technology and information encryption technology, designes and implementes the transportation monitoring system based on Internet of Things, and each module of this system to be tested. Experimental data show that this system effectively solved the real-time monitoring and data security issues during the whole transport process.Concrete work this paper done as follows:During the research of the real-time monitoring problem, in-depth studying of networking technology, this paper puts forward the real-time monitoring strategy which with RFID (Radio Frequency Identification) technology, GPS positioning technology and GPRS technology as the core. The real-time monitoring strategy implementes the function of obtaining details information of goods, positioning location information of goods, transmitting the monitor information, thereby improves the accuracy and real-time of the transport monitoring system, realizes real-time monitor of the transport items.In view of the monitoring data safety transmission problem, this paper proposes a comprehensive strategy based on security data encryption algorithm and Message Digest Algorithm. This strategy uses AES encryption algorithm for transport information encrypt and SHA-1algorithm for digital signature, ensures the security of the transport information during transportation and realizes the detection of the sources of the transportation information, integrity and reliability. For transport terminal system performance optimization problem, this paper proposes a bottom-up, layer by layer optimize mobile operating system optimization strategy. This strategy improves transportion-oriented terminal system by rebuilding the services and features of Android system, thereby improves the performance of the transport terminal software.Implemented and validated the transportation monitoring system based on Internet of Things. The test data show that Internet of Things technology can achieve a good real-time monitoring of the transportation goods; data security strategy ensures the security, integrity, reliability of transport information and realizes the safety management of transport goods; transport terminal system performance optimization strategy simplifies the services of Android system and improves the performance of the transport terminal software.
