Description

Technical Field

[0001] The utility model relates to the technical field of traffic engineering equipment, in particular to an infrared vehicle detection device for a highway. Background Art

[0002] When a rear-end collision or car accident occurs on the highway, a chain rear-end collision often occurs. This is because the driver driving behind cannot be informed of the accident in front in a short period of time, resulting in untimely braking, which in turn causes multiple high-speed vehicles to collide in a chain, resulting in a chain accident.

[0003] In the prior art background, when a traffic accident occurs on a highway, the driver needs to set up a warning sign at the rear to notify the vehicles behind. However, it takes a long time from the occurrence of the accident to the setting up of the warning sign, during which time another traffic accident is very likely to occur. Especially when the accident victims are seriously injured and unable to move, there is a lack of warning signs at the rear, which makes chain accidents prone to occur. In addition, the warning range of the vehicle warning sign is small, and by the time the vehicle finds the warning sign and brakes, it is often too late. Therefore, a highway infrared vehicle detection device is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] See also Figure 1-Figure 4 , a highway infrared vehicle detection device, comprising an equipment frame 1, a vehicle detection mechanism 3 is arranged inside the equipment frame 1, and a cleaning mechanism 2 is arranged at the outer end of the equipment frame 1;

[0022] The vehicle detection mechanism 3 includes an infrared signal transmitter 301, an infrared signal receiver 302, a warning light 303 and a controller 304. The equipment rack 1 is a "door"-shaped structure. The infrared signal receiver 302 is installed in the equipment rack 1 away from the infrared signal transmitter 301. The infrared signal transmitter 301, the infrared signal receiver 302 and the warning light 303 are connected to the controller 304 by wires.

[0023] When the device is in use, a group of equipment racks 1 are set at intervals of several meters on accident-prone sections of the highway. When a vehicle passes by the equipment rack 1, the signal emitted by the infrared signal transmitter 301 is blocked by the vehicle, resulting in the infrared signal receiver 302 being unable to receive the infrared signal within a certain period of time. The signal disconnection time of the infrared signal receiver 302 of the first group of equipment racks 1 is t1, and the time to receive the infrared signal again is t2. The signal disconnection time of the infrared signal receiver 302 of the second group of equipment racks 1 several meters away is t1, and the time to receive the signal again is t3. The average length of the vehicle is l, and the speed of the vehicle when passing the first group of equipment racks is t1. Assume that the distance between the two groups of equipment racks 1 is s, then the speed of the vehicle between the first group of equipment racks 1 and the second group of equipment racks 1 is When v1 or v1 is too small, the controller 304 controls the warning light 303 to flash to warn of an accident deceleration. Or when the vehicle passes the first group of equipment racks 1 and the second group of equipment racks 1 does not detect a signal disconnection for a long time after the vehicle passes the first group of equipment racks 1, the controller 304 also controls the warning light 303 to warn of an accident.
