[Abstract]:Intelligent Transportation system (its) effectively utilizes the advanced communication, information and control technology in the Internet of things to realize the real-time, accurate and efficient management of transportation. With the introduction of Internet of things (IoT) technology, the service mode and system architecture of Intelligent Transportation system (its) have changed greatly. Wireless sensor network, telecommunication network, internet and so on exist in the intelligent transportation system based on the Internet of things. The network environment of the system becomes extremely complex. How to realize these network interconnection is a difficult problem for the intelligent transportation system. Gateway is the key equipment to solve this problem. In this paper, the intelligent transportation system architecture and related theories in the Internet of things environment are studied carefully, and a design scheme of intelligent transportation system gateway based on the Internet of things is proposed and implemented. At the same time, for the application of intelligent transportation system gateway, a gateway deployment algorithm is proposed. In this paper, the related technologies of Intelligent Transportation system Gateway are introduced, and the functional requirements of the Gateway are analyzed, and the gateway hierarchy model and the overall scheme are designed. Then, the gateway hardware circuit is designed according to the overall scheme, and the gateway application software is designed according to the function requirement. The experimental and simulation results show that the Intelligent Transportation system Gateway based on the Internet of things can create ZigBee network and connect it to GPRS network by wireless mode and Ethernet by wire mode. It realizes the multi-mode access and multi-protocol conversion of the gateway. The Gateway deployment algorithm can obtain the Gateway deployment strategy.
