Description

Technical Field

[0001] This invention relates to the field of carbon emission detection technology, specifically a method for calculating the implicit carbon emissions of highway service areas. Background Technology

[0002] With global warming, carbon emissions, primarily referring to carbon dioxide emissions, are receiving increasing attention. It is estimated that automobiles account for nearly a quarter of total carbon dioxide emissions. As the number of vehicles increases, carbon dioxide emissions also rise, making it necessary to monitor vehicle carbon emissions.

[0003] Among them, vehicles produce higher levels of carbon dioxide when traveling at high speeds, making carbon dioxide detection equipment more commonly used on highways. However, it is rarely installed in highway service areas, resulting in inaccurate carbon dioxide test results. In addition, the test results of carbon dioxide detection devices are greatly deviated in severe weather conditions, rendering them meaningless. Furthermore, carbon dioxide detection devices exposed to severe weather conditions are prone to damage. Summary of the Invention

Step 2: Activate the carbon emission detection device and move the video recognition equipment to the outside of the carbon emission detection device: Step 3: Carbon emission testing is conducted. After the vehicle enters and leaves the highway service area, the carbon emission testing device acquires a photo of the vehicle and sends it to the central control room. The central control room compares the photo with the vehicle's model information and uses this information to calculate: Q= ; Where Q represents the total CO2 emissions; The total distance traveled by each mode of transport within the highway service area; The emission factor for each mode of transport; Step 4: The central control room records the corresponding carbon emissions based on the model information of the vehicles and records vehicles that exceed the carbon emission standards.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0030] Please see Figure 1 In this embodiment of the invention, a method for calculating the implicit carbon emissions of highway service areas includes the following steps: Step 1: Install the carbon emission detection device at the entrance and exit of the highway and enable the carbon emission detection device to communicate with the central control room, which is equipped with a database for storing vehicle model information. Step 2: Activate the carbon emission detection device and move the video recognition device 18 to the outside of the carbon emission detection device: Step 3: Carbon emission testing is conducted. After the vehicle enters and leaves the highway service area, the carbon emission testing device acquires a photo of the vehicle and sends it to the central control room. The central control room compares the photo with the vehicle's model information and uses this information to calculate: Q= ; Where Q represents the total CO2 emissions; The total distance traveled by each mode of transport within the highway service area; The emission factor for each mode of transport; Step 4: The central control room records the corresponding carbon emissions based on the model information of the vehicles and records vehicles that exceed the carbon emission standards.

[0031] By detecting carbon emissions generated by vehicles in service areas, the results of vehicle carbon emission testing are made more accurate. Furthermore, the detection of vehicle carbon emissions can help understand the vehicle's operating status, prevent vehicle malfunctions at high speeds, and improve highway driving safety and traffic efficiency.

[0032] Please see Figures 2-10 The carbon emission detection device includes a connecting base 1, an adjustment component, a sealing plate 21, and a power component. This allows the video recognition device 18 to enter the protective enclosure 26 under adverse weather conditions, protecting it from damage. Furthermore, once inside the enclosure 26, the sealing plate 21 blocks the through-hole 2601, preventing external dust and other debris from entering the enclosure 26 and causing corrosion or short circuits to the internal components of the video recognition device 18. This improves the operational stability and durability of the video recognition device 18.

[0033] Specifically, the connecting seat 1 is provided with a protective box 26, and a through hole 2601 is formed on one side of the protective box 26; The adjustment assembly connects the connecting base 1 and the protective box 26. The adjustment assembly includes a rotating structure and a deflecting structure. The rotating structure and the deflecting structure cooperate to adjust the orientation of the protective box 26. The rotating structure includes a fixed shaft 2 fixedly installed on the connecting seat 1 and a rotating shaft 3 coaxial with the fixed shaft 2. A connecting protrusion 201 is formed at the end of the fixed shaft 2 away from the connecting seat 1. The connecting protrusion 201 is rotatably connected to the connecting groove 301 provided on the rotating shaft 3. The rotating structure also includes a first drive device 4 fixedly installed on the fixed shaft 2. A gear 5 is coaxially fixed on the output shaft of the first drive device 4. The gear 5 meshes with a gear ring 6 provided on the rotating shaft 3. The gear ring 6 is coaxially fixedly connected to the rotating shaft 3. The deflection structure includes a rotating component 8 that is rotatably connected to one end of the rotating shaft 3 away from the fixed shaft 2, and the rotating component 8 is fixedly connected to the protective box 26. An electric telescopic rod 7 is fixedly installed on the rotating shaft 3, and a pulley 9 is rotatably installed on the actuating end of the electric telescopic rod 7; A horizontal plate 10 perpendicular to the rotating component 8 is fixed on it. The horizontal plate 10 has a horizontal groove 1001 along its length, and the pulley 9 can roll in the horizontal groove 1001.

[0034] The connecting seat 1 is provided with a base 27, and a connector 28 is fixedly installed on the connecting seat 1. A spherical cavity 2801 is formed inside the connector 28, and the connecting ball head 29 fixedly installed on the base 27 can rotate inside the spherical cavity 2801. The connecting seat 1 is also provided with a plurality of energy storage components 30 arranged equidistantly in a circle, and the end of the energy storage component 30 away from the connecting seat 1 is connected to the base 27.

[0035] Before use, the base 27 is bolted to the gantry at the highway entrance and exit. During use, the central control room can control the operation of the first drive device 4 and the electric telescopic rod 7. Specifically, when the first drive device 4 is working, the output shaft of the first drive device 4 will drive the gear 5 connected to it to rotate. The gear 5 and the gear ring 6 are in a meshing state. When the gear 5 rotates, it can drive the gear ring 6 to rotate. At this time, the gear ring 6 can drive the rotating shaft 3 to rotate relative to the fixed shaft 2, so that the protective box 26 follows the rotating shaft 3 to rotate, so that the video recognition device 18 can make a circular motion about the fixed shaft 2. When the electric telescopic rod 7 is activated, the actuating end of the electric telescopic rod 7 will drive the pulley 9 to rise and fall along the length of the rotating shaft 3. The pulley 9 rolls in the transverse groove 1001, so that when the height of the pulley 9 changes, the horizontal plate 10 can drive the protective box 26 to rotate through the rotating part 8, thereby changing the pitch angle of the video recognition device 18.

[0036] With the above settings, when the first drive device 4 is working, it can drive the video recognition device 18 to make circular motion, and when the electric telescopic rod 7 moves, it can change the pitch angle of the video recognition device 18. The two work together to enable the video recognition device 18 to change position within a certain field of view, thereby improving the recognition range and recognition accuracy of the video recognition device 18.

[0037] Furthermore, all the energy storage components 30 are in a stretched state in the initial state so that the connecting seat 1 and the base 27 can remain parallel in the initial state. When the video recognition device 18 moves relative to the connecting seat 1, its movement will generate vibration. If the vibration force acts directly on the base 27, it may cause the connection stability between the base 27 and the gantry to decrease, and the vibration may cause damage to the internal components of the video recognition device 18. In this application, the vibration generated when the video recognition device 18 moves is absorbed by the multiple energy storage components 30, thereby ensuring the connection stability between the base 27 and the gantry, improving the stability of the video recognition device 18 during operation and its durability during use.

[0038] The electric telescopic rod 7 mentioned above can also be replaced by a pneumatic cylinder or a hydraulic cylinder. All three are existing technologies, and this application will not elaborate on them in detail. The best option can be chosen based on the actual usage conditions.

[0039] Please see Figures 7-9 The sealing plate 21 is disposed inside the protective box 26, and the sealing plate 21 can change the conduction state of the through hole 2601; The power assembly is disposed inside the protective box 26 and connected to the video recognition device 18. The power assembly can drive the video recognition device 18 to move toward the outside of the protective box 26. The power assembly is also connected to the abutment component connected to the sealing plate 21. The abutment component is used to drive the sealing plate 21 to move upward when the video recognition device 18 moves toward the outside of the protective box 26, thereby opening the through hole 2601. The power assembly includes two drive wheels 12 rotatably mounted on the protective box 26, and a drive belt 13 is sleeved between the two drive wheels 12. One of the drive wheels 12 is connected to a second drive device 11 fixed on the protective box 26. Two reflective electrodes 1301 are symmetrically arranged on the drive belt 13. The reflective electrodes 1301 are adapted to a distance sensor 17 fixedly mounted on the inner wall of the protective box 26. The power assembly also includes a fitting structure disposed inside the protective box 26 and connected to the transmission belt 13. The fitting structure includes a follower plate 15 fixedly connected to the video recognition device 18. The follower plate 15 is provided with a fitting groove 1501, and the grooved wheel 14 rotatably mounted on the transmission belt 13 can roll in the fitting groove 1501. The protective box 26 is also equipped with at least two crossbars 16, and the follower plate 15 can slide along the length direction of the crossbars 16; Two guide members 20 are symmetrically installed inside the protective box 26, and the sealing plate 21 is slidably installed between the two guide members 20; The abutting assembly includes a connecting plate 22 fixedly connected to the sealing plate 21. An abutting wheel 23 is rotatably mounted on one end of the connecting plate 22 away from the sealing plate 21. A trigger 19 mounted on the follower plate 15 is adapted to the abutting wheel 23. The abutting assembly also includes an elastic structure connecting the protective box 26 and the connecting plate 22. The elastic structure includes a vertical shaft 24 installed inside the protective box 26. The vertical shaft 24 is slidably connected to a collar disposed on the connecting plate 22. A spring 25 is also fitted on the vertical shaft 24. One end of the spring 25 is connected to the collar, and the other end is connected to the inner wall of the protective box 26.

[0040] When encountering extreme weather conditions (such as heavy fog or sandstorms), the second drive device 11 is activated. The output shaft of the second drive device 11 will drive the transmission wheel 12 connected to it to rotate, and cause the transmission belt 13 sleeved on the transmission wheel 12 to move. At this time, the grooved wheel 14 will follow the transmission belt 13 and, in cooperation with the fitting groove 1501, drive the follower plate 15 to move along the length of the crossbar 16 toward the inside of the protective box 26, so that the video recognition device 18 can enter the inside of the protective box 26, thus preventing the severe weather from damaging the lens module of the video recognition device 18.

[0041] Furthermore, when the follower plate 15 moves to the end of its stroke, the reflector 1301 on the transmission belt 13 will emit infrared light generated by the distance sensor 17, and when the distance sensor 17 receives the reflected infrared light, it will control the second drive device 11 to stop working, thereby improving the position accuracy of the video recognition device 18 during movement.

[0042] When the video recognition device 18 protrudes from the protective box 26, the abutment wheel 23 is positioned above the trigger 19. At this time, the through hole 2601 is in a conductive state, and the spring 25 is in a compressed state. When the video recognition device 18 moves toward the interior of the protective box 26 following the follower plate 15, the abutment wheel 23 will cooperate with the trigger 19. After the video recognition device 18 enters the protective box 26, the sealing plate 21 will move downward under the action of the spring 25 to seal the through hole 2601. This prevents external dust and other debris from entering the interior of the protective box 26 and causing corrosion and short circuits to the internal components of the video recognition device 18, thereby improving the operational stability and durability of the video recognition device 18.

[0043] With the above-mentioned configuration, the video recognition device 18 can be placed inside the protective box 26 under severe weather conditions, thus protecting it from damage. Furthermore, once inside the protective box 26, the sealing plate 21 blocks the through-hole 2601, preventing external dust and other debris from entering the protective box 26 and causing corrosion or short circuits to the internal components of the video recognition device 18. This improves the operational stability and durability of the video recognition device 18.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
