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] like 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 communicatively connected to the control terminal;

[0038] The control terminal obtains the real-time point cloud data from the lidar and the real-time position data of the mobile terminal, and performs path planning according to the real-time position 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 mode and...

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 the small car cuts into the road maintenance area at an inclination angle of 10° (the included angle with the road center line), the early warning system alarms, 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] First, set the conditions, and people 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 work area;

[0051] Human response time: the fastest human respons...

Abstract

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 to the control terminal in communication; the control terminal acquires real-time point cloud data from the laser radar and real-time Location data, path planning based on 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; The obtained 3D point cloud data is used for path planning to ensure the safety warning effect.

Description

technical field [0001] The present disclosure relates to the technical field of safety warning robots, and in particular, to an accompanying system of a road maintenance safety warning robot. Background technique [0002] The statements in this section merely provide background related to the present disclosure and do not necessarily constitute prior art. [0003] When the expressway is open to traffic, vehicles are usually in a fast driving state, and there is a high safety risk in road maintenance and construction. In the process of driving, the expressway belongs to the fast driving space, and the vehicle driving to the operation area at this time can easily pose a greater threat to the life safety of maintenance operators or maintenance personnel or maintenance equipment. In addition, in the process of highway driving, high-speed driving will affect the driver's vision, resulting in blind spots of vision. In addition, long-term driving will cause the driver to become fa...
