Embodiment Construction

[0036] The present invention will be further described below in conjunction with accompanying drawing.

[0037] figure 1It is the layout diagram of the expressway toll system in the present invention, and the expressway toll system is divided into a front end and a back end; the front end system is a reliably connected local area network composed of toll lanes and toll stations; the back end system is a provincial expressway management The business management service system of the center is realized through the cloud platform system, which provides background support for the front-end system and connection with other systems. A reliable, continuous, and uninterrupted communication connection needs to be established between the front-end system and the back-end system, that is, a reliable transmission channel is required.

[0038] In order to solve the above-mentioned technical problems, this embodiment increases wireless public network backup on the basis of the private netwo...

Abstract

The invention proposes a multichannel connection communication method for a highway tolling system, and the method comprises the steps: setting a central intelligent router at a highway management center, and respectively setting station intelligent routers at all toll stations under the administration of the highway management center; building three data transmission channels between the central intelligent router and each station intelligent router: a private network wired channel, a public network wired VPN channel and a public wireless VPN channel; setting different priorities for all data transmission channels, and achieving nearly uninterrupted data transmission between a front end toll station and a rear end highway management center for the highway tolling system according to a priority gating data transmission channel through intelligent router management.

Description

technical field [0001] The invention relates to the field of intelligent traffic charging, in particular to a multi-channel connection communication method for a highway charging system. Background technique [0002] Private network communication refers to the communication network built within some industries, departments or units to meet their needs for organizational management, safe production, dispatching and commanding. The highway toll system involves a lot of traffic information and toll information, and has high requirements for the reliability, security, and real-time performance of data transmission. At present, each expressway has built a special network to realize the data transmission of the toll system. At present, the expressway communication system generally adopts the intelligent optical network technology based on optical fiber communication, and with the construction of the road network, the communication network also forms a mesh network, which provides...
