Active anti-collision intelligent distance measuring system of road roller and control method of system

The invention relates to an active anti-collision intelligent distance measuring system of a road roller. The system comprises a road roller central control system, a middle control panel, a front ultrasonic distance measuring slave station, a rear ultrasonic distance measuring slave station, a left ultrasonic distance measuring slave station, a right ultrasonic distance measuring slave station and other RS485 bus node slave stations, wherein the ultrasonic distance measuring slave stations are respectively arranged around a road roller body; the corresponding slave stations are used for measuring the nearest distance and azimuth information of target obstacles in front of, behind, on the left and on the right of the road roller in real time, and the middle control panel acquires summarized information processed by the slave stations according to a set time interval, performs error control and information processing, and sends a final data processing result to the road roller central control system.
