Application of proximity switch sensor in super-large bridge


At 12 o'clock today, April 2, the second Humen Bridge project in Dawan District of Guangdong, Hong Kong and Macao was officially opened to traffic. This new channel will open up new arteries for the interconnection of Guangdong, Hong Kong and Macao, and promote the rapid development of the economy of the Great Bay Area.
Macher proximity switch sensor, inductance proximity switch long-distance detection sensor, capacitance proximity switch sensor, acid-alkali proximity sensor and salt-fog proximity sensor are first used in large quantities in the electric control system of river-crossing bridges. The leakage of pollutants and harmful chemical liquids into the river and sea is detected and alarmed, which provides environmental protection for the water area under bridges from pollution.

During the construction period, the first generation BIM construction and maintenance integrated information platform with independent intellectual property rights has been developed, which combines new technologies such as mobile internet, Internet of things and robots to realize the deep integration of information technology and engineering construction and maintenance technology, so as to make the "intelligent construction site" of engineering construction and "intelligent manufacturing" of steel structure from conception to reality.
It is the first time in the world that two super-long-span suspension bridges of the second Humen Bridge Project have been constructed at the same time. The super-large bridge is a symbol of the economic and technological strength of an era and a region. The main line of the second Humen Bridge project adopts the bridge mode, and two extra-large bridges across the river are set up. "Significant, large-scale, complex technology" is the most prominent label given to the second Humen Bridge project in the industry.
