Description

Technical Field

[0001] The utility model relates to the technical field of vehicle height measuring equipment, in particular to a high-speed toll station vehicle height measuring equipment with a disassembly and assembly structure. Background Art

[0002] A vehicle height detector is a device used to measure the height of a vehicle. It is installed at the entrance or exit of a highway toll booth. It helps toll booth staff ensure that vehicles that are too high do not pass through the toll booth to ensure road safety. Commonly used vehicle height measurement devices in highway toll booths are vehicle height limit signs and suspended sensors. Vehicle height limit signs: These signs are usually set at the entrance and exit of toll booths to alert drivers to the maximum height limit of the vehicle. The specific height limit value will be marked on the sign, and the driver needs to ensure that the height of the vehicle is lower than this value in order to pass through the toll booth smoothly; suspended sensors: These sensors are installed on the top of the toll booth channel to measure the height of the vehicle as it passes. They usually use laser or infrared sensing technology to measure. When the height of the vehicle exceeds the set limit, the sensor will trigger a warning signal to notify the toll booth staff to take further measures. These two devices play an important role in highway toll booths, helping to ensure that vehicles that are too high do not pass through the toll booth to prevent potential accidents or damage.
