Problems solved by technology

During the driving process, the expressway is a fast driving space. At this time, when the vehicle travels to the work area, it is easy to cause a greater threat to the life safety of maintenance workers or maintenance personnel or maintenance equipment.
In addition, during highway driving, high-speed driving will affect the driver's vision and cause blind spots in the field of vision. In addition, long-term driving will cause driver fatigue, and the safety distance and the speed of other vehicles cannot be accurately grasped. Increased likelihood of accidents
[0004] The inventor found that most of the existing maintenance safety warning robots are fixed at a preset position for early warning of vehicle intrusion, the degree of autonomy is low, and the staff is constantly moving to work. Realize alarm reminder; at the same time, most of the existing safety warning systems simply use cameras or other monitoring equipment to realize vehicle monitoring, and there are few road cones in the maintenance area, often only providing safety warnings, and lack of personnel monitoring design for safe escape

Embodiment 1

[0037] Such as figure 1 As shown, Embodiment 1 of the present disclosure provides an accompanying system for a road maintenance safety warning robot, including: a control terminal and a laser radar, and the laser radar is connected in communication with the control terminal;

[0038] The control terminal obtains the real-time point cloud data from the lidar and the real-time location data of the mobile terminal, and performs path planning according to the real-time location data and real-time point cloud data, so that the distance between the control terminal and the mobile terminal is within the preset control range.

[0039] This embodiment effectively integrates the design of radio frequency tracking and positioning technology, laser ranging technology, obstacle avoidance and navigation technology, and artificial intelligence technology at the strategy layer, and realizes the automatic following and autonomous obstacle avoidance of related products. Switch between follow mo...

Embodiment 2

[0044] Embodiment 2 of the present disclosure provides a road maintenance safety warning robot, including the accompanying system of the road maintenance safety warning robot described in Embodiment 1.

Embodiment 3

[0046] This embodiment provides an intelligent road cone warning system, in the case of high-speed driving, such as figure 2 As shown, when a small car cuts into the road maintenance area at an inclination angle of 10° (the angle with the center line of the road), the early warning system will give an alarm, and the road maintenance personnel can just avoid the intruding vehicle. Intelligent road cones, at this time, the placement interval of intelligent road cones is L 4 =12.96m.

[0047] The working principle of this embodiment is:

[0048] Firstly, the conditions are set, and the person should have enough time to avoid the vehicle after the system alarms;

[0049] Vehicle speed setting: V=80km / h (22m / s) without deceleration;

[0050] According to the actual driving situation, set the driving position as the centerline of the expressway, and set the working position of the maintenance workers as near the centerline of the working area;

[0051] Human reaction time: the ...

Abstract

The invention provides an accompanying system for a road maintenance safety warning robot. The system comprises a control terminal and a laser radar, and the laser radar is in communication connection with the control terminal. The control terminal acquires real-time point cloud data transmitted by the laser radar and real-time position data of the mobile terminal, and performs path planning according to the real-time position data and the real-time point cloud data, so that the distance between the control terminal and the mobile terminal is within a preset control range. The real-time distance tracking of the mobile intelligent terminal worn by the worker is realized, and the path planning is carried out based on the three-dimensional point cloud data obtained in real time, so that the safety warning effect is ensured.

Description

technical field [0001] The present disclosure relates to the technical field of safety warning robots, in particular to an accompanying system for road maintenance safety warning robots. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] When the expressway is open to traffic, the vehicles are usually in a fast-moving state, and there are high safety risks in road maintenance and construction operations. During the driving process, the expressway is a fast driving space. At this time, when the vehicle travels to the work area, it is easy to cause a greater threat to the life safety of maintenance workers or maintenance personnel or maintenance equipment. In addition, during highway driving, high-speed driving will affect the driver's vision and cause blind spots in the field of vision. In addition, long-term driving will cause driver fatig...
