Description

Technical Field

[0001] The present invention relates to the technical field of carbon emission monitoring, and specifically, to a monitoring device for traffic carbon emissions. Background Art

[0002] With the gradual change of the climate in modern society, in order to protect the environment and reduce the impact brought by the greenhouse effect, people have gradually begun to pay attention to the carbon emissions of various vehicles on road traffic, so as to reduce the problem of the damage caused by the carbon dioxide emitted during the driving of vehicles to the environment.

[0003] The commonly used method for monitoring carbon emissions on road traffic is generally to install carbon dioxide sensors on both sides of the road. After a vehicle passes by one side of the carbon dioxide sensor, the carbon emissions in the vehicle exhaust are detected to achieve the monitoring effect of vehicle carbon emissions. However, when this method detects the vehicle exhaust, it does not have the function of collecting the exhaust. Limited by the environmental impact, after the exhaust is emitted from the vehicle, it will quickly disperse into the environment. Therefore, it is difficult to control the accuracy of detecting the carbon emissions in the vehicle exhaust using a carbon dioxide sensor. Another method for monitoring vehicle carbon emissions is the non-dispersive infrared detection method. In this monitoring method, a non-dispersive infrared emission device is set on one side of the road, and then an infrared induction detection device is correspondingly set on the other side of the road. By detecting the change in the intensity wavelength of the infrared ray after passing through the exhaust, the carbon emissions in the vehicle exhaust are judged. This method of use is relatively accurate. However, because the driving speeds of vehicles are not consistent, and also because of the problem that the exhaust quickly disperses after being discharged, it is easy to cause the non-dispersive infrared monitoring method to be difficult to detect the carbon emissions of the exhaust accurately enough.

After the position of the ranging sensor device corresponds to the car's exhaust gas emission position, under the action of the encoder, the moving paths between the first corresponding moving mechanism and the second corresponding moving mechanism are matched, and the carbon emission detection mechanism is moved below the car's exhaust gas emission position. Then, when the ranging sensor device detects that most of the car has moved out of the installation frame, the sliding lifting assembly drives the carbon emission detection device to rise, samples and collects the exhaust gas emitted by the car and conducts detection, realizing the detection of the carbon emissions of the exhaust gas of cars on the road traffic and playing the role of monitoring the traffic carbon emissions.

[0016] 2. Therefore, when the monitoring device for traffic carbon emissions detects the carbon emissions of vehicles traveling on the road traffic, it will not affect the normal driving of the car. There is no need for the driver to specifically drive the car to the detection area for detection. And when detecting the car's exhaust gas, it can collect and detect the exhaust gas emitted by the car in a timely manner, avoiding the influence of the external environment on the exhaust gas concentration and ensuring the accuracy of the monitoring of the exhaust gas carbon emissions.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts fall within the scope of the present invention.

The speed measurement device 6 is provided on both brackets 2, and the distance measurement device 7 is provided on both brackets 2. When it is necessary to detect the carbon emissions of the vehicle exhaust on the road traffic, during the movement of the vehicle between the two brackets 2, the distance measurement device 7 is used to measure the driving position of the vehicle on the road, judge the driving position of the vehicle on the road, and determine the distance measurement sensing device 4 and the carbon emission detection mechanism 200 corresponding to the vehicle. Then, the speed measurement device 6 is used to detect the driving speed of the vehicle and judge the time when the vehicle passes the top of the installation frame 5. The monitoring camera device 3 is used to detect the vehicle information and the exhaust emission position. In the prior art, the monitoring camera devices 3 used on road traffic have all been equipped with image capture technology, which can detect the details of the vehicles driving on the road traffic and judge the exhaust emission position at the vehicle tail. The monitoring camera device 3, the speed measurement device 6, and the distance measurement device 7 used in the present invention are all well-known prior art devices in the art and are also common technical devices on road traffic in the prior art.

[0022] It further includes a distance measurement sensing device 4, an installation frame 5, and a second corresponding moving mechanism 400. A plurality of distance measurement sensing devices 4 are slidably arranged in the installation bridge 1.

The first corresponding moving mechanism 100 includes a sliding member 8, a transmission lead screw 9, a first driving motor 10, and an engagement assembly. A slide rail is fixedly connected inside the installation bridge 1. The plurality of distance measurement sensing devices 4 are all slidably connected to the slide rail through the sliding member 8. The transmission lead screw 9 is rotatably connected inside the installation bridge 1. An encoder 11 is arranged between the transmission lead screw 9 and the installation bridge 1. A plurality of first threaded cylinders 12 are threadedly connected to the transmission lead screw 9. The first threaded cylinders 12 correspond to the distance measurement sensing devices 4 one by one. The first driving motor 10 is arranged on the installation bridge 1. The output end of the first driving motor 10 is fixedly connected to the transmission lead screw 9. When it is necessary to adjust the position of the distance measurement sensing device 4, the first driving motor 10 is started to drive the transmission lead screw 9 to rotate, so that the transmission lead screw 9 drives the first threaded cylinders 12 to rotate together. However, after the first threaded cylinder 12 meshes with the corresponding sliding member 8, due to the sliding connection relationship between the sliding member 8 and the installation bridge 1, at this time, the first threaded cylinder 12 will drive the sliding member 8 to move horizontally together to adjust the position of the distance measurement sensing device 4; A corresponding sliding member 8 and the first threaded cylinder 12 are provided with an engagement assembly. The engagement assembly includes a rotating shaft 13, a second driving motor 14, an engaging member 15, and an engagement slot 16. A rotating groove is formed on the sliding member 8. The rotating shaft 13 is rotatably connected in the rotating groove. A second driving motor 14 is arranged on the sliding member 8. The output end of the second driving motor 14 is fixedly connected to the rotating shaft 13. An engaging member 15 is fixedly connected to the rotating shaft 13. An engagement slot 16 corresponding to the engaging member 15 is fixedly connected to the first threaded cylinder 12. When the second driving motor 14 is started to drive the rotating shaft 13 to rotate, the rotating shaft 13 drives the engaging member 15 to flip along the center point of the rotating shaft 13. The engaging member 15 enters the engagement slot 16, so that the engaging member 15 and the engagement slot 16 are kept engaged. Then, when the driving lead screw 9 drives the first threaded cylinder 12 to move, the first threaded cylinder 12 can drive the ranging sensing device 4 to move.

[0023] It further includes a lens 17. A through groove is formed on one side of the mounting bridge 1 facing the mounting frame 5. The lens 17 is arranged in the through groove. After the position of the ranging sensing device 4 is moved, the laser ray emitted by the ranging sensing device 4 can measure the moving position of the vehicle. After the exhaust emission position of the vehicle is detected by the monitoring camera device 3, the ranging sensing device 4 is moved to a position corresponding to the vehicle exhaust emission area. After the wheel area of the vehicle detected by the ranging sensing device 4 moves out of the mounting frame 5, when the vehicle exhaust emission area is about to pass above the mounting frame 5, after the ranging sensing device 4 accurately measures the moving position of the vehicle, it is prompted that the mounting box 20 is moved out of the mounting frame 5. The lens 17 is provided to protect the ranging sensing device 4 and does not affect the normal use of the ranging sensing device 4. The ranging sensing device 4 is a known prior art device in the art.

[0024] It further includes an access slot and a bending fixing member 18. An access slot is formed at the top of the mounting frame 5. A plurality of shielding sheets 19 are arranged in the access slot. The plurality of shielding sheets 19 are grouped in pairs. A plurality of bending fixing members 18 are fixedly connected to both sides of the mounting frame 5. After the mounting frame 5 is installed in the concrete road surface, the bending fixing member 18 is used to fully contact the inside of the concrete road surface to fixedly install the mounting frame 5. During the normal use of each device inside the mounting frame 5, in order to prevent dust in the external environment from entering the mounting frame 5, a plurality of shielding sheets 19 are used to close the access slot. The lengths between two shielding sheets 19 in the same group are inconsistent, so that the joints between the longitudinally arranged plurality of shielding sheets 19 do not correspond. Therefore, when the mounting box 20 is moved out of the mounting frame 5, the shielding sheets 19 contact the surface of the mounting box 20 to prevent dust in the external environment from entering the mounting frame 5. It should be noted that in case of rain or snow weather, try not to detect the traffic carbon emissions, and a cover is needed to close the access slot.

The carbon emission detection mechanism 200 includes an installation box body 20 and a negative pressure fan 21. A detection cylinder body 22 is fixedly connected inside the installation box body 20. A plurality of exhaust holes are formed in the bottom of the installation box body 20. A negative pressure fan 21 is arranged at the inner bottom of the installation box body 20. Among them, an infrared emission device 23 is arranged on one side of the detection cylinder body 22, and an induction detection device 24 is arranged on the other side of the detection cylinder body 22. When the installation box body 20 is moved out of the installation frame 5 and the installation box body 20 is located directly below the vehicle exhaust emission area, the negative pressure fan 21 is started to draw the exhaust gas into the detection cylinder body 22, and then the infrared emission device 23 is started to emit non-dispersive infrared rays. The infrared rays pass through the exhaust gas in the detection cylinder body 22 and are detected by the induction detection device 24 on the other side. By judging the attenuation degree and wavelength of the infrared rays, the carbon emission in the exhaust gas is judged. The infrared emission device 23 and the induction detection device 24 are both existing technical devices well-known to those skilled in the art and are based on the application of non-dispersive infrared photoelectric (NDIR) detection technology.

The output end of the fourth driving motor 31 is fixedly connected with the rotating lead screw 30. A plurality of second threaded cylinders 32 are threadedly connected to the rotating lead screw 30. The second threaded cylinders 32 correspond one-to-one with the bent sliding frames 25. When it is necessary to adjust the positions of the bent sliding frames 25 and the installation box 20, the fourth driving motor 31 is started to drive the rotating lead screw 30 to rotate, so that the second threaded cylinders 32 rotate following the rotating lead screw 30. After the bent sliding frames 25 are connected to the second threaded cylinders 32 by using the connection component, when the second threaded cylinders 32 move, they drive the bent sliding frames 25 to move together to adjust the position of the installation box 20. It should be added that encoders 11 are arranged on both the transmission lead screw 9 and the rotating lead screw 30, and the models and dimensions of the transmission lead screw 9 and the rotating lead screw 30 are the same.

[0027] The working principle of this traffic carbon emission monitoring device: When it is necessary to monitor the carbon emissions in the exhaust gas of a car traveling on the road, after the car passes between the two brackets 2, the ranging device 7 detects the distance between the car and the closer bracket 2 after the car passes, determines the exhaust gas emission position during the car's road travel, then uses the speed measurement device 6 to calculate the car's traveling speed, determines the time when the car passes the top of the installation frame 5, and after the car passes the bottom of the installation bridge 1, the monitoring camera device 3 captures the exhaust gas emission position at the rear of the car, starts the first drive motor 10 to drive the transmission lead screw 9 to rotate, and makes the transmission lead screw 9 drive the first threaded cylinder 12 to rotate together. However, after the first threaded cylinder 12 meshes with the corresponding sliding member 8, due to the sliding connection relationship between the sliding member 8 and the installation bridge 1, at this time, the first threaded cylinder 12 will drive the sliding member 8 to move horizontally together to adjust the position of the ranging sensor device 4; During the rotation of the transmission lead screw 9, the fourth drive motor 31 is started to drive the rotating lead screw 30 to rotate, and the second threaded cylinder 32 rotates following the rotating lead screw 30. After using the connection component to connect the bent sliding frame 25 with the second threaded cylinder 32, when the second threaded cylinder 32 moves, it drives the bent sliding frame 25 to move together to adjust the position of the installation box 20. After the position of the ranging sensor device 4 corresponds to the exhaust gas emission position of the car, the carbon emission detection mechanism 200 is moved below the exhaust gas emission position of the car. Then, when the ranging sensor device 4 detects that most of the car has moved out of the installation frame 5, the sliding lifting component 300 drives the carbon emission detection device to rise, samples and collects the exhaust gas emitted by the car and conducts detection, realizing the detection of the carbon emissions of the exhaust gas of cars on the road traffic and playing the monitoring operation of traffic carbon emissions.
