Problems solved by technology

[0004] At present, the reasons for traffic accidents at highway entrances, especially those with heavy traffic flow, are as follows: first, the driver’s sight distance is limited, and the situation of the main road cannot be effectively grasped; The meteorological conditions on the road surface lead to vehicle collisions due to the failure to reduce the speed in time; the third is that there is no reminder when the ramp speeds up, resulting in a large turning radius when turning at the entrance, and traffic accidents with vehicles on the main road

Embodiment 1

[0037] A safety early warning system for highway ramp access. The security warning system is figure 1 As shown, it includes information detection equipment, intelligent control equipment 1, dedicated short-range communication equipment 6, vehicle-mounted equipment and power supply control cabinet.

[0038] The information detection equipment consists of a video detector 2, a first L-shaped frame 3, a second L-shaped frame 7, an embedded road condition detector 4 and a vehicle type detector 8. The first L-shaped frame 3 is arranged on the outside of the main road outer lane 5, and the distance between the first L-shaped frame 3 and the entrance of the ramp is 100 ~ 150m. The video detector 2 is installed on the first L-shaped frame 3, and the video detection The center of the device 2 is positioned directly above the center line of the outer lane 5 of the main road. Embedded road condition detector 4 is located under the road surface at the center of the main road outer lane ...

Embodiment 2

[0057] A safety early warning system for highway ramp access. Except following technical parameter, all the other are with embodiment 1.

[0058] The distance between the first L-shaped frame 3 and the entrance of the ramp is 150-200m;

[0059] The distance between the second L-shaped frame 7 and the outer lane 5 of the main road is 40 ~ 50m;

[0060] The distance between the intelligent control device 1 and the entrance of the ramp is 150-200m, and the intelligent control device 1 is one of a computer, an integrated microcomputer and a single-chip microcomputer.

[0061] This specific embodiment gathers the real-time information of the current road ramp entrance at the video detector 2 installed at the entrance of the ramp, the embedded road condition detector 4 and the detection equipment of the type detector 8, and carries out data processing through the intelligent control device 1. Fusion processing, and then wirelessly transmit to the vehicle-mounted equipment through ...

Abstract

The invention relates to a safety forewarning system for a road ramp junction port. The scheme of the system is as follows: a video detector (2) is installed right above the center line of a main-road outer lane (5); a buried-type road surface condition detector (4) is arranged under a road surface at the center of the main-road outer lane (5) of the ramp junction port; a vehicle-model detector (8) is installed right above the center line of a ramp lane; an intelligent control device (1) is installed at the outer side of the main-road outer lane (5); and a special short-range communication device (6) is installed at one side of the ramp junction port. A vehicle-mounted information processing module of a vehicle-mounted device is connected with a vehicle-mounted information wireless receiving module and a vehicle-mounted information displaying module. The intelligent control device (1) is connected with the video detector (2), the buried-type road surface condition detector (4), the special short-range communication device (6) and the vehicle-model detector (8) through optical cables. The safety forewarning system for the road ramp junction port is capable of detecting a vehicle condition and a road condition of the ramp junction port in a real-time manner with a high precision and carrying out screen and voice alarms so that dynamic security forewarning is realized.

Description

technical field [0001] The invention belongs to the technical field of safety early warning systems, and in particular relates to a safety early warning system for highway ramp entrances. Background technique [0002] The main function of highway is to provide high-quality transportation services, which is the most direct infrastructure for economic development. At present, travel on the trunk roads in the plains has changed from being fast and convenient in the past to today's speed reduction, numerous disturbances and frequent traffic accidents due to the increase in traffic volume. Although the local government, transportation management department, and construction department are actively managing the entrances connected to the red line of road construction, due to the large number of management departments involved and the scope of involvement is too wide, the problem of ramp entrances in arterial highway sections has been left unsolved for a long time. However, traffi...
