WanJi supplied ETC system for Hong Kong-Zhuhai-Macao Bridge

Date:2018-11-22

On October 24th, the world-famous Hong Kong-Zhuhai-Macao Bridge was officially running. This bridge is the longest sea-crossing bridge in the world. Hong Kong-Zhuhai-Macao Bridge Project is called the “big integration” of bridge and tunnel technology. WanJi supplied all the ETC RSU transceiver for two-way 20 ETC lanes at this bridge. The journey time between Zhuhai, Macao and Hong Kong has been shortened from 3 hours to 30 minutes. Wanji ETC system has been highly praised as the advanced, stable and efficient system.

The Hong Kong-Zhuhai-Macao Bridge ETC system had extremely high technical requirements. Wanji Technology used customized solutions to continuously overcome technical difficulties. The bridge was equipped with the national standard ETC and Hong Kong Express. In order to avoid signal interference between equipment, WanJi microwave team has passed hundreds of debugging of the irradiation range and intensity of the phased array antenna module. What’s more, WanJi ETC R&D team spent half a year to achieve uniform coverage of the signal at the transaction distance. Additional, WanJi ETC R&D engineers conducted a large number of research and verification in Shandong, Jiangxi, and Qinghai for 4 months. They made a great effort to do optimization algorithm, Therefore, Wanji improves the accuracy of DBF, which not only improves the accuracy of antenna positioning, but also further consolidates Wanji technical advantages in ETC industry. As a result, WanJi has guaranteed the vehicle to charge successfully at one time in a limited transaction distance. WanJi's DBF positioning technology has made great breakthrough.

 

In the past two years, Wanji Technology has solved countless industry problems. In Hong Kong-Zhuhai-Macao Bridge project, WanJi undoubtedly demonstrates strong technical strength.
