Embodiment Construction

[0030] The unmanned road roller rolling system in the tunnel without satellite signal, including road roller, paver, and reference station, is characterized in that it consists of multiple steel wheel road rollers and rubber wheel road rollers equipped with unmanned control systems to form an unmanned road roller The road roller fleet 102, the construction route planning system set on the paver 101, the mobile reference station and the microwave communication system 103 constitute an unmanned road roller rolling system in the tunnel without satellite signals ( figure 1 );

[0031] At the left and right wheel axle positions of the steel wheel roller and the front and rear left and right positions of the rubber wheel roller body, a laser lateral distance measuring sensor 207 is respectively arranged at an angle of 90 degrees to the driving direction; The sidewall of the drainage ditch 105 is used as a reference, and the distance between the roller wheel and the sidewall of the d...

Abstract

The invention discloses an unmanned road roller rolling system in a tunnel without a satellite signal. The unmanned road roller rolling system in the tunnel without the satellite signal is characterized in that an unmanned road roller group composed of a plurality of road rollers, a path planning system arranged on a paver, and a mobile reference station form the unmanned road roller rolling system in the tunnel without the satellite signal; lateral laser distance measuring sensors are laterally arranged at the positions of the left side and the right side in front and back of a vehicle body of each road roller in a manner of forming a 90-degree angle with a running direction separately; the sidewall of a drainage ditch in the tunnel is taken as a reference substance, distances between vehicle wheels of each road roller and the sidewall of the drainage ditch are tested through the laser distance measuring sensors arranged on the road roller to set the running track of each amplitude of the road roller; the running of each road roller is controlled through microwave communication, and operating personnel of the road roller are prevented from working under an environment of mixing emitted tail gas and a high-temperature asphalt mixture; and the advantages of effectively protecting the occupational health of the operating personnel of each road roller is realized, avoiding the harm of poisonous and harmful substances to human bodies, and ensuring the rolling quality for an asphalt road surface in the tunnel.

Description

technical field [0001] The invention relates to an intelligent control system for road construction equipment in the construction machinery industry, specifically a rolling system for unmanned road rollers in tunnels without satellite signals. Background technique [0002] With the development of science and technology, the advantages of intelligent control technology in the current social and economic development are becoming more and more prominent. Unmanned vehicles have launched a research and development boom of various models around the world. However, construction machinery and equipment in the construction machinery industry have not yet been recognized. Intelligent control technology development team and engineering equipment manufacturers attach great importance to it. Among many construction machinery, the working characteristics of road rollers are repetitive, regular, and single working environment. The operation is relatively simple, and the operators are prone...
