Introduction: On October 24th, it is a memorable day for the Chinese. The "Super Project" Hong Kong-Zhuhai-Macao Bridge, which is known as the "Chinese Miracle" by foreign media, was officially opened to traffic. This proud bridge has created many of the world's best.

The parking garage in the Macao Port Management District is a basement with six floors above ground, with an area of ​​about 180,000 square meters, a basement elevation of 6.5 meters and a 20-meter-high overall structure. After the completion of the management area project, it became the only port in China that connects the Hong Kong and Macao Special Administrative Regions at the same time and became a new landmark.
Zhongjiao Road Construction Beijing Ruituo Electronic Technology Co., Ltd. undertook the construction of the parking garage electrical and mechanical project in the Macau Port Management Zone of Hong Kong-Zhuhai-Macao Bridge. In order to ensure the lighting of the Hong Kong-Zhuhai-Macao Bridge Macao Port project, the remaining major engineering quantities on the ground floor and from the first floor to the fifth floor are the installation of the power distribution cabinet in the power distribution room and the internal pressure connection of the power distribution cabinet; the ground floor and the circular ramp lamps About 20,000 sets of installations; 3,000 meters of cable trays; about 50,000 meters of cable laying; 6 of each floor in the distribution room, a total of 36; realized important tasks such as systemized parking and other intelligent control of the parking garage in the country, let Beautiful and gorgeous lights illuminate the ocean, perfect for the task.
The high standards and strict requirements of the Hong Kong-Zhuhai-Macao Bridge are not only reflected in the main project of the bridge, but also in the lighting of the bridge. The Hong Kong-Zhuhai-Macao Bridge project has higher requirements for lighting than the average person. The complex shape determines the richness of the lighting form. Every product applied to the bridge must be customized and specially processed. This also presents the LED driver power supply. Strict requirements, in addition to providing basic lighting functions, also meet the above special requirements. Under such high requirements and high standards, many lighting companies supporting the bridge have chosen to use Infineon's LED driver power supply, which proves that the impression of Infineon's high-quality products and high-efficiency services has been deeply rooted in the continuous development.

Shanghai Sansi provides streetlights, tunnel lights and other products for the bridge. In fact, it is very important to have the same product, that is, the LED variable information board provides display information for passing vehicles. The LED variable information board used in the Hong Kong-Zhuhai-Macao Bridge project will ensure the original technological advantages and adopt a number of new technologies and materials to prevent salt spray, vibration, ultraviolet light and high and low temperature. The release of traffic information and the operation of traffic guidance functions.

Zhouming Technology participated in the LED display construction project of Zhuhai Port of Hong Kong-Zhuhai-Macao Bridge. In order to welcome the opening ceremony of the bridge, Zhou Ming lit up eight high-definition full-color LEDs with a total area of ​​326 square meters at the Zhuhai Port Travel Inspection Building of Hong Kong-Zhuhai-Macao Bridge. The display has high-intensity windproof, salt-proof and moisture-proof grades, and the display effect is high-definition and vivid.
Intelligent control system

It is unbeatable to talk about the beauty and magic of the Hong Kong-Zhuhai-Macao Bridge. In addition to its beautiful and distinctive style, it is mainly due to the superb design and high-level construction of 12 intelligent control systems such as lighting, communication, monitoring, water supply and drainage, making the bridge more intelligent and smart. The operation links are modernized, intelligent and automated. The responsibility of this responsibility is the four companies of China Railway Construction Electrification Bureau.
Because the bridge is a "giant overall system", not only the intelligent control systems are interwoven and interspersed, but also have many internal and external interfaces. They also interact with various control and control systems such as civil engineering and the three ports. Every detail is Take one to launch the whole body.
For the first time in construction, they adopted the most advanced engineering construction management standard BIM system in the world to supervise the whole process of project construction. Through three-dimensional display, the construction progress can be viewed at any time, and more than 3,000 kilometers of cables, more than 20,000 kilometers of optical cables, and 1,280 intelligent street lights are marked and managed to realize real-time data update, ensuring the steady progress of the entire project construction.
