Description

Technical Field

[0001] The utility model relates to the technical field of road safety warning, in particular to an intelligent sentry warning system. Background Technique

[0002] The level crossing is the hub of the road traffic network, bringing together traffic participants in multiple different directions. Motor vehicles, non-motor vehicles and pedestrians pass through it, and the traffic is complex, making it extremely easy to cause traffic safety accidents, especially at the level crossings of the main roads and branch roads of national and provincial roads without traffic signal control and imperfect traffic markings. According to data statistics, 80% of traffic accidents occur at intersections. Therefore, it is particularly important to add an intelligent intersection sentry system at intersections.

[0003] In the Chinese utility model patent application number: CN201620067933.7, there is disclosed a traffic warning system for a level crossing without traffic lights, including a detection device, an acoustic-optic warning device, a controller and a lithium battery. The detection device is arranged on the first upright post and stands on one side of the main road, and the acoustic-optic warning device is arranged on the second upright post and stands on one side of the secondary road. The detection device, the acoustic-optic warning device and the controller are wirelessly connected to form a warning system. For this traffic warning system for a level crossing without traffic lights, at least two upright posts need to be arranged, and the arrangement is relatively inconvenient. By integrating the detection device and the acoustic-optic warning device on one upright post, the above problem can be avoided. However, due to the different angles between the intersections of the main roads and branch roads at different intersections, there is still a problem that the orientation of the detection device is inconvenient to adjust.

[0004] Therefore, it is very necessary to propose an intelligent sentry warning system to solve the above problems. Content of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] Please refer to Figures 1 - 3 As shown, an intelligent sentry warning system includes a bracket 4, a warning module and a first speed measurement and monitoring device 1. The warning module is fixedly connected to one side of the bracket 4; the bottom end of the first speed measurement and monitoring device 1 is fixedly connected with a rotating shaft 14, the rotating shaft 14 is rotatably connected with the bracket 4, the bottom end of the rotating shaft 14 is slidably connected with a first end gear disc 10 along its axial direction, a positioning shaft 12 is arranged inside the bracket 4, and the top end of the positioning shaft 12 is fixedly connected with a second end gear disc 11 meshing with the first end gear disc 10. A spring 9 for driving the first end gear disc 10 to reset is sleeved outside the rotating shaft 14.

[0026] During use, the bracket 4 is fixed at the intersection of the main road and the branch road, the warning module is oriented towards the branch road, and then the first speed measurement and monitoring device 1 is rotated to face the main road. When the first speed measurement and monitoring device 1 detects a vehicle coming from the main road, the first speed measurement and monitoring device 1 is controlled to start to warn the vehicles on the branch road of the vehicle coming from the main road and avoid traffic accidents.

[0027] In some embodiments, the positioning shaft 12 is fixedly connected to the bracket 4.

[0028] When rotating the first speed measurement and monitoring device 1, the first speed measurement and monitoring device 1 drives the first end gear disc 10 to rotate. The first end gear disc 10 slides upward along the rotating shaft 14, and the spring 9 is compressed by the force. When the first end gear disc 10 meshes with the second end gear disc 11 again, the spring 9 pushes the first end gear disc 10 to reset. At the same time, under the action of the elastic force of the spring 9, a downward pressure is applied to the first end gear disc 10 to prevent the first speed measurement and monitoring device 1 from rotating.

[0029] Specifically, the cross section of the bottom end of the rotating shaft 14 is rectangular, and a rectangular hole adapted to it is opened in the middle of the first end gear disc 10 to prevent the first end gear disc 10 from rotating relative to the rotating shaft 14.

[0030] In some embodiments, to facilitate remotely adjusting the orientation of the first speed measurement and monitoring device 1, the positioning shaft 12 is rotatably connected to the bracket 4. A worm gear 13 is fixedly connected to the outer side of the positioning shaft 12, and a servo motor 8 is fixedly connected to the inner side of the bracket 4. A worm 7 adapted to the worm gear 13 is fixedly connected to the output shaft of the servo motor 8.

[0031] During adjustment, the servo motor 8 is started. The servo motor 8 drives the positioning shaft 12 to rotate through the worm 7 and the worm gear 13, and the positioning shaft 12 drives the rotating shaft 14 to rotate, thereby realizing the adjustment of the orientation of the first speed measurement and monitoring device 1. At the same time, the worm 7 and the worm gear 13 are used for transmission, which has a self-locking function to prevent the first speed measurement and monitoring device 1 from rotating.

[0032] In some embodiments, the bracket 4 is a hollow housing. A base 5 is fixedly connected to the bottom end of the bracket 4, and a through hole 6 is formed in the base 5. During installation, a concrete pile is buried on the roadside, the base 5 is placed on the concrete pile and the embedded bolts pass through the through hole 6, and then they are fixed by nuts.

[0033] In some embodiments, the warning module includes a warning light 2 and a display screen 3. The warning light 2 and the display screen 3 are both fixedly connected to the inner side of the hollow housing. Transparent windows are provided at positions of the hollow housing corresponding to the warning light 2 and the display screen 3. The warning light 2 and the display screen 3 can be protected through the housing and the transparent windows. Preferably, the warning light is a red and blue flashing light, and the display screen 3 is an LED display screen to warn or give early warnings to passing vehicles in text.

[0034] When applied to intersections with many pedestrians and non-motor vehicles, the warning module further includes a loudspeaker, and the loudspeaker is fixedly connected to the bracket 4. A prompt sound is played through the loudspeaker to prompt pedestrians and non-motor vehicles.

[0035] In some embodiments, a second speed measurement and monitoring device 15 is further included. The first speed measurement and monitoring device 1, the second speed measurement and monitoring device 15, and the warning module are all electrically connected to a controller, and the controller is communicatively connected to a cloud platform through a network module.

[0036] When the first speed measurement and monitoring device 1 is blocked by an obstacle and it is inconvenient to obtain information about main road vehicles, the second speed measurement and monitoring device 15 is deployed on the main road to obtain information about main road vehicles, and the orientation of the first speed measurement and monitoring device 1 is adjusted so that it is used to obtain information about branch roads. When vehicles are detected by both of them, the warning module is started to warn branch road vehicles that there are vehicles coming from the main road. At the same time, by setting the first speed measurement and monitoring device 1 and the second speed measurement and monitoring device 15, it is avoided that the warning module is started when there are vehicles on the main road and no vehicles on the branch road, reducing energy consumption. By communicatively connecting the controller to the cloud platform, it is connected to a GIS-based background system for remote monitoring and remote parameter setting.

[0037] Specifically, both the first speed measurement and monitoring device 1 and the second speed measurement and monitoring device 15 include a radar speedometer and a camera.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
