Automatic safety warning system for concomitant maintenance operations

Abstract

In recent years, the process of expressway construction has been accelerating, and operators need to carry out daily maintenance of the expressway. At the same time, expressway belongs to fast driving space. High speed driving will create a blind area of vision for operators, seriously threaten the life safety of maintenance operators, and cause great damage to the life and property safety of road maintenance personnel, maintenance operators and drivers. Based on this, the team designed and developed an active safety warning robot and intelligent road cone for accompanying maintenance operation. The robot body integrates a number of technical equipment such as visible light camera, audible and visual alarm and collision early warning radar. The robot can not only push the early warning information, but also accept the collapse signal of intelligent road cone and push the multi-sensory early warning signal. The intelligent road cone is equipped with RFID chip and balance sensor, which can push the early warning signal according to the collapse. The early warning system can effectively solve the early warning problems for the safety of operators and social vehicles when out of control vehicles break into the maintenance area in the process of expressway maintenance.
