The invention discloses a real-time pavement evenness monitoring system. The real-time pavement evenness monitoring system comprises an acceleration sensor for acquiring bumping inertia force of an automobile running on a pavement in real time, a speed encoder for acquiring an automobile speed signal in real time, a data acquisition card for converting signals output by the acceleration sensor and the speed encoder into digital signals, and a main controller for receiving the digital signals output by the data acquisition card and calculating the pavement evenness according to the automobile bumping, wherein the output end of the main controller is connected with a printer for printing the pavement evenness calculated by the main controller, the output end of the main controller is connected with a display for displaying the pavement evenness calculated by the main controller, and the data acquisition card is connected with a 5V power supply system. The real-time pavement evenness monitoring system has a simple structure, can be used conveniently, has a good monitoring effect on the pavement evenness, is low in production cost and can be promoted and used conveniently.
Description
technical field [0001] The invention relates to a monitoring system, in particular to a real-time monitoring system for road surface smoothness. Background technique [0002] There are currently three types of instruments for testing road surface roughness: cross-section instrument, reaction instrument and inertial instrument. The disadvantage of these methods is that it must rely on manual operation for measurement, and the speed is relatively slow, so it cannot be applied to the measurement of road surface flatness at the network level. The disadvantage of the reactive leveling instrument is that it does not directly measure the road profile, but measures the vehicle's response to changes in the road profile, which may be affected by the vehicle's own suspension system or shock absorber system. In addition, such instruments need to measure at a fixed speed, or to develop a speed correction mode, which is very inconvenient. In contrast, the inertial leveling instrument is...
