Open highways such as national highways, provincial highways, and county roads are an important part of my country's transportation network, and are also important routes in the transportation process of freight vehicles. Vehicles traveling on national/provincial/county roads are inspected for over-limit and overloading. Under the requirements of intelligent traffic construction for off-site control and law enforcement of over-limited and overloaded vehicles, Zonjli provides a highway non-stop over-limit detection system, which realizes high-speed collection of driving vehicle weight, license plate, speed and vehicle photos, and can be uploaded to the over-limit control system. The management platform provides law enforcement basis for law enforcement departments such as road administration and supermarket management centers and punishes illegal vehicles.

Bridges are an important part of the road network to ensure smooth road connections across water canals. Urban elevated roads are an important traffic network to quickly improve urban traffic efficiency; , Freight vehicles on urban elevated roads do not stop and do not slow down detection, realize weight data collection and docking with the overtaking control platform, meet the off-site law enforcement management of illegal vehicles by the urban administer overloading center, and effectively prevent overweight and overloaded vehicles from passing bridges and entering urban elevated roads , Cause road damage or danger or even traffic accidents, reduce bridges and urban elevated operation and maintenance costs, and build urban intelligent traffic.

Bridge health monitoring is to issue early warning signals for bridges under various traffic conditions or when bridge operation conditions are abnormally serious through the monitoring of bridge structural conditions, and provide basis and guidance for bridge maintenance and repair and management decisions.
