Application of Beidou satellite timing server on Expressway

In August 2019, the Beidou satellite time server, which was produced by our company, was successfully put into operation in the Henan Provincial Expressway Project and the Hebei Provincial Expressway project. It provides standard time information for the safety of expressway traffic system network in these two provinces, so that all terminals of the expressway system can achieve a unified function of time.

The most important equipment for canceling toll toll stations and realizing electronic toll collection is the ETC gantry system, which has the functions of segmental traffic charging, traffic investigation, video surveillance and speeding screening. In order to be able to achieve the standard and impartial realization of all vehicles passing through and accurate timing charging,In accordance with the state's abolition of the overall deployment of toll toll stations at the Provincial Expressway, the electronic toll collection system will be fully implemented after being put into operation.The function of Beidou satellite time server is to provide standard time information for ETC gantry system and other equipment, so as to achieve the time standard unified function.

Our company is working together, closely cooperating, coordinating and coordinating, and working with high standards and strict requirements to complete the basic Beidou satellite time server device test installation, system joint debugging and other work, and strive to make this project a model demonstration for the National Expressway synchronous clock project, leading the province to cancel the provincial toll collection station work comprehensively and efficiently.

The value of the Beidou satellite timing server on expressways is reflected in the following aspects:

First, the function of the Beidou time server is to upgrade the central and local two level clearing and settlement and operation management system. The toll lane, ETC gantry system hardware, toll booth and software are unified in time, so that the time charge is standardized.

Two, the satellite time server also speeds up the construction and improvement of the highway toll system.The satellite time server can also make the electronic toll collection fast, with the license plate image recognition and the integration of various payment means.It is necessary to keep the hardware and software of the central and local electronic toll collection system up to two seconds, and enhance the system network security.

Through on-site commissioning of the Beidou time server continuous optimization plan, gradually debugged the ETC gantry system hardware, supplemented by license plate image recognition software and hardware, webcam, NVR and other equipment, and did not have any problems.

The value of satellite timing system

ETC is an electronic toll collection system that is being developed and promoted internationally for roads, bridges and tunnels.The technology has a long history in foreign countries, and the electronic toll collection system in many countries and regions such as the United States and Europe has been partially connected and gradually formed scale benefit.With the IC card and magnetic card as the medium, the toll collection method based on manual charging is undoubtedly affected by this trend. Therefore, it is particularly important that a complete set of time server is needed to escort the entire expressway.
