Description

Technical field:

[0001] The utility model relates to the technical field of intelligent traffic, in particular to an intelligent traffic signal light device at a level crossing. Background technology:

[0002] At present, there are many level crossings on national highways, provincial highways, county roads, and township roads. Among them, many level crossings have more vehicles on the main roads, but fewer pedestrians crossing the road. Therefore, some of these level crossings are now only equipped with yellow flashing lights to remind vehicles on the main roads to slow down. Although the traffic efficiency of the main roads is improved, there are certain safety hazards when pedestrians cross the road, which is easy to cause traffic accidents; some are directly equipped with traffic lights. Although safety is improved, sometimes there are no pedestrians crossing the road, and vehicles on the main roads have to stop and wait when they encounter red lights, thereby reducing the traffic efficiency of the main roads. In view of the above situation, an intelligent traffic control system has appeared on the market, which usually uses a weighing device to sense weight signals to determine the presence of pedestrians, thereby controlling the signal lights. For example, the patent application with publication number CN106530753A discloses an intelligent traffic light control system, which configures a human body sensor at a traffic node, specifically a weighing device, and uses the weighing device to feedback weight to identify the number of people. Currently, there are very few weighing devices that can be used at traffic intersections, and due to their structural limitations, they cannot effectively weigh pedestrians, bicycles, etc., which can easily lead to inaccurate weighing, resulting in deviations in signal feedback, thus affecting the accurate control of traffic lights.

The weighing sensor then sends the weight signal to the control device. The weight signal feedback is accurate and there will be no deviation, which is conducive to the control device to accurately control the signal light; at the same time, the pedestrian needs to press the control button on the button rod. When the control device receives the weight signal of the weighing sensor and the signal of the control button at the same time, the control device detects that a pedestrian needs to cross the road, and then delays a certain time to control the signal light to switch the signal. The main road turns red and the level crossing turns green. Pedestrians can cross the road safely, eliminating safety hazards. The control device controls the signal switch again after a certain delay, so that vehicles on the main road can pass normally. If the control device does not receive the signal of the weighing sensor and the control button for a long time, the main road will continue to keep the green light, thereby improving the traffic efficiency of the main road.

Specific implementation method:

[0025] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

A plurality of sensor assemblies 4 are installed in the box body 1, and the sensor assembly 4 includes a mounting plate 5 fixed in the box body 1, and a transmission rod 6 inclined upward is installed on the top of the mounting plate 5, and a weighing sensor 7 matched with the bottom surface of the transmission rod 6 is installed on the mounting plate 5. The top of the transmission rod 6 contacts and cooperates with the upper cover 2 and transmits the weight signal to the weighing sensor 7. The weighing sensor 7 is used to send the weight signal to the control device, and the control device controls the signal conversion of the traffic light 25 according to the signal of the weighing sensor 7 and the control button 24.

[0027] The guide assembly 3 includes a guide cylinder 8 vertically arranged in the box body 1, and an upper boss guide column 9 and a lower boss guide column 10 are respectively inserted at the top and bottom of the guide cylinder 8. The bottom boss of the lower boss guide column 10 cooperates with the bottom of the guide cylinder 8 to clamp and fix the bottom of the box body 1.

A spring 11 is sleeved on the outer side of the upper boss guide column 9 between the bottom surface of the upper cover 2 and the top of the guide cylinder 8. Several groups of ball assemblies for guiding the upper boss guide column 9 are vertically installed in the side wall of the guide cylinder 8.

[0028] The ball assembly includes a ball groove vertically arranged on the side wall of the guide cylinder 8, and a plurality of balls 12 are arranged in the ball groove. The side opening of the ball groove is smaller than the diameter of the ball 12 to prevent the ball 12 from escaping. The ball 12 rolls and contacts with the upper boss guide column 9 from the leaked part of the ball groove. The top of the ball groove is installed with a ball baffle 13 by screws to limit the top of the ball 12. When the upper cover 2 is deformed by pressure and displaced downward, the upper cover 2 drives the upper boss guide column 9 to move downward, and the ball 12 can guide the upper boss guide column 9. There is enough space in the guide cylinder 8 for the upper boss guide column 9 to move downward. When the upper cover 2 loses pressure, under the elastic action of the spring 11, the spring 11 drives the upper boss guide column 9 to move upward, and the upper boss guide column 9 drives the upper cover 2 to reset upward.

[0029] The bottom boss of the lower boss guide column 10 is flush with the bottom surface of the box body 1, so that the bottom is flat and stable to install, and the top boss of the upper boss guide column 9 is flush with the top surface of the upper cover 2, so that the top is flat and beautiful.

The top of the operation hole 17 is provided with a cover plate 18 for sealing, and the top surface of the cover plate 18 is flush with the top surface of the upper cover 2.

[0034] A camera 26 is installed on the top of the side button rod 23 , and a lighting lamp 27 is installed on the top of the middle button rod 23 .

[0035] Platforms 28 are respectively provided on both sides of the side weighing sensor device 20 , and corner rubber plates 29 are provided at the positions where the platforms 28 and the side weighing sensor device 20 are connected.

[0036] Working principle:

[0037] When in use, the side weighing sensor device 20 and the middle weighing sensor device 22 of the utility model can be used in a manner of being installed in parallel. When pedestrians, bicycles, electric bicycles, etc. stand on the upper cover 2 and need to pass through the intersection, the upper cover 2 is deformed by pressure and displaced downward. The guide component 3 can guide the upper cover 2 when it moves. When the upper cover 2 moves downward, it drives the transmission rod 6 to move. The transmission rod 6 transmits the weight signal to the weighing sensor 7, and the weighing sensor 7 sends the weight signal to the control device. At the same time, the pedestrian needs to press the control button 24 on the button rod 23. When the control device receives the weight signal of the weighing sensor 7 and the signal of the control button 24 at the same time, the control device detects that a pedestrian needs to cross the road, and then delays a certain time to control the signal light to switch the signal. The main road 19 becomes a red light and the level crossing becomes a green light. Pedestrians can cross the road safely, eliminating safety hazards. The control device delays a certain time and controls the signal switch again to ensure that the main road 19 vehicles can pass normally after the pedestrians cross the road. If the control device does not receive the signal from the weighing sensor 7 and the control button 24 for a long time, the main road 19 will continue to keep the green light, thereby improving the traffic efficiency of the main road 19. If a pedestrian is left on the intermediate weighing sensor device 22 under special circumstances, similarly, the weighing sensor 7 of the intermediate weighing sensor device 22 can send a weight signal to the control device, and the pedestrian needs to press the control button 24 on the button rod 23. The control device delays a certain time to control the signal light to switch the signal, the main road 19 turns red, and the level crossing turns green, ensuring that pedestrians can cross the road safely.

[0038] The above specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.

[0039] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
