[0001] The utility model relates to the technical field of intelligent transportation, in particular to an intelligent transportation weighing sensor device. Background technology:

[0002] Currently, in intelligent traffic control systems, weighing devices are usually used to sense weight signals to determine the presence of pedestrians and thus control traffic lights. For example, patent application publication number CN106530753A discloses an intelligent traffic light control system that configures human body sensors at traffic nodes, specifically using weighing devices, and uses the weight feedback from the weighing devices 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., and are prone to inaccurate weighing, resulting in deviations in signal feedback, which in turn affects the accurate control of traffic lights.

[0003] To sum up, the weighing problem in intelligent traffic control systems has become a technical problem that needs to be solved urgently in the industry. Utility model content:

[0004] In order to make up for the deficiencies of the prior art, the utility model provides an intelligent traffic weighing sensor device, which solves the problems of inaccurate weighing and deviation in signal feedback of previous weighing devices.

Several groups of ball assemblies for guiding the upper boss guide column are vertically installed in the side wall of the guide cylinder.

[0008] The ball assembly includes a ball groove vertically arranged on the side wall of the guide cylinder, a plurality of balls are arranged in the ball groove, the balls are in rolling contact with the upper boss guide column, and a ball baffle is installed on the top of the ball groove by screws.

[0009] The bottom boss of the lower boss guide column is flush with the bottom surface of the box body, and the top boss of the upper boss guide column is flush with the top surface of the upper cover.

[0010] A light strip groove is provided on the upper surface of the upper cover, a three-color light strip is provided in the light strip groove, and an acrylic light panel is installed on the top of the light strip groove.

[0011] The bottom of the transmission rod is fixedly connected to the mounting plate, and the transmission rod is reset by relying on its own elasticity.

[0014] The utility model adopts the above solution and has the following advantages:

[0015] When pedestrians, bicycles, electric bicycles, etc. stand on the upper cover, the upper cover is compressed and deformed, driving the transmission rod to move. The weight signal is transmitted to the weighing sensor through the transmission rod, and 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 beneficial for the control device to accurately control the signal light.

Specific implementation method:

[0022] In order to clearly illustrate the technical features of this solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0023] like Figure 1-5 As shown, an intelligent traffic weighing sensor device includes a box body 1, a top cover 2 is provided on the top of the box body 1, and several guide components 3 are provided between the upper cover 2 and the box body 1. The guide components 3 are used to guide and assist in resetting the upper cover 2 when it is deformed under pressure and displaced. Several sensor components 4 are installed in the box body 1, and the sensor components 4 include a mounting plate 5 fixed in the box body 1. 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.

[0024] The guide assembly 3 includes a guide cylinder 8 vertically arranged in the box body 1, and the top and bottom of the guide cylinder 8 are respectively inserted with an upper boss guide column 9 and a lower boss guide column 10. The bottom boss of the lower boss guide column 10 cooperates with the bottom of the guide cylinder 8 to clamp the bottom of the box body 1. The top boss of the upper boss guide column 9 is clamped in the countersunk hole of the upper cover 2. A spring 11 is provided 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.

[0025] The ball assembly includes a ball groove vertically arranged on the side wall of the guide cylinder 8. 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 balls 12 to prevent the balls 12 from escaping. The balls 12 leaking out of the ball groove roll in contact with the upper boss guide column 9. A ball baffle 13 is screwed to the top of the ball groove to limit the top of the balls 12. When the upper cover 2 is compressed and deformed and displaced downward, the upper cover 2 drives the upper boss guide column 9 downward, and the balls 12 can guide the upper boss guide column 9. There is sufficient space in the guide cylinder 8 for the upper boss guide column 9 to move downward. When the upper cover 2 loses pressure, the spring 11 elastically drives the upper boss guide column 9 to move upward, and the upper boss guide column 9 then drives the upper cover 2 to return to its original position.

[0026] The bottom boss of the lower boss guide column 10 is flush with the bottom surface of the box body 1, making the bottom flat and stable. The top boss of the upper boss guide column 9 is flush with the top surface of the upper cover 2, making the top flat and beautiful.

[0027] The upper surface of the upper cover 2 is provided with a light strip groove, in which a three-color light strip 14 is provided, and an acrylic light board 15 is installed on the top of the light strip groove. The three-color light strip 14 is connected to the control device, which can control the color of the three-color light strip 14 when it is lit to be consistent with the color of the intersection signal light.

[0028] The bottom of the transmission rod 6 is fixedly connected to the mounting plate 5 , and the transmission rod 6 is reset by its own elasticity.

[0029] The bottom of the transmission rod 6 is rotatably connected to the mounting plate 5 via a rotating shaft, a torsion spring is installed on the rotating shaft, and the transmission rod 6 is reset by the elasticity of the torsion spring.

[0030] The bottom of the box body 1 is provided with a plurality of expansion bolt holes 16, and the upper cover 2 is provided with operation holes 17 at positions corresponding to the expansion bolt holes 16. The expansion bolts can be installed in the expansion bolt holes 16 through the operation holes 17, thereby fixing the box body 1 to the ground. 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.

[0031] Working principle:

[0032] During use, the present intelligent traffic weighing sensor device can be installed in multiple units side by side. When a pedestrian, bicycle, or electric bicycle stands on the upper cover 2, the upper cover 2 is compressed and deformed, causing it to move downward. The guide assembly 3 guides the upper cover 2 as it moves downward, driving the transmission rod 6 to move. The transmission rod 6 transmits a weight signal to the weighing sensor 7, which in turn sends the weight signal to the control device, which detects the presence of the pedestrian. When the pressure on the upper cover 2 is removed, the guide assembly 3 resets the upper cover 2 so that the next weighing operation can be repeated.

[0033] The above specific implementation methods 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 transformation made to the implementation methods of the present utility model falls within the protection scope of the present utility model.

[0034] Anything not described in detail in the present invention is well known to those skilled in the art.
