Pavement friction coefficient detection device

Abstract

The invention discloses a pavement friction coefficient detection device, which consists of a fixed seat, a movable seat, a lifting apparatus and a detector. One end of the movable seat is hinged to the fixed seat, the lifting apparatus is fixedly mounted on the fixed seat, and a power output end of the lifting apparatus is connected to the movable seat to drive the movable seat to swing; the detector is installed on the movable seat; the detector includes a distance sensor, a control chip, a roller and a first motor, the roller is slidably mounted on the movable seat through a connecting seat, the first motor is fixedly installed on the connecting seat, and an output shaft of the first motor is fixedly connected to the roller, and the roller contacts the pavement; and the distance sensor is electrically connected to the control chip to detect the sliding distance of the roller, and transmits the data to the control chip, and the control chip times the movement time of the roller, thus obtaining a pavement friction coefficient. The detection device provided by the invention has the advantages of automatic detection, simple structure, convenience and rapidity.

Description

technical field [0001] The invention belongs to the technical field of bicycle equipment and relates to a bell, in particular to a road surface friction coefficient detection device. Background technique [0002] At present, our country has less automation equipment in maintaining traffic safety. Especially in rainy and snowy weather, there is a lack of equipment on the road to automatically detect the friction coefficient of the road surface, and the corresponding safe speed value of the vehicle is obtained through the detected data, and the obtained safe speed value is displayed to the passing car owner, so that the car owner can Slow down in time to improve traffic safety and reduce accidents. However, the existing detection vehicles for detecting road surface friction are all manually operated to detect the friction coefficient of the road surface, which is not only time-consuming, laborious and costly, but also cannot reach the destination in time in sudden rainy and s...
