Description

Technical Field

[0001] This utility model relates to the field of remote sensing technology for motor vehicle exhaust emissions, and in particular to a remote sensing monitoring device for converting vertical to horizontal motor vehicle exhaust emissions. Background Technology

[0002] In the field of vehicle exhaust emission monitoring, accurate detection of vehicle exhaust emissions is of great significance for environmental protection. Existing remote sensing monitoring equipment mainly employs two detection modes: vertical and horizontal. In the vertical detection mode, the transmitting unit emits a detection beam towards the ground below the lane, relying on a ground reflector to reflect the beam for reception by the receiving unit. However, the installation and maintenance of the ground reflector is cumbersome and easily affected by ground conditions. In the horizontal detection mode, the transmitting and receiving units need to be horizontally positioned opposite each other on both sides of the lane, placing high demands on the installation conditions on both sides of the lane. The two modes are usually independent, making it difficult to switch flexibly according to the actual detection scenario, thus limiting the applicability and flexibility of the equipment. Different equipment may need to be installed separately in different detection environments, increasing costs and wasting resources. To solve these problems, a remote sensing monitoring device capable of switching between vertical and horizontal detection modes has been developed to improve the device's versatility and detection efficiency.

[0022] The remote sensing monitoring device for converting vertical to horizontal emission of motor vehicle exhaust in this embodiment includes a transmitting unit 1, a receiving unit 2, and a convertible bracket 3 to switch between vertical and horizontal detection modes.

[0023] In vertical detection mode, the transmitting unit 1 emits a detection beam towards the ground of the lane below, and a ground reflector 4 is provided on the ground. The receiving unit 2 receives the beam reflected by the retroreflection device of the ground reflector 4.

[0024] In the horizontal detection mode, the transmitting unit 1 and the receiving unit 2 are arranged opposite each other on both sides of the motor vehicle lane in the horizontal direction, and the transmitting unit 1 emits a detection beam that passes through the lane to the receiving unit 2 on the opposite side;

[0025] The convertible bracket 3 includes a support column 31 positioned relative to the lane. One of the support columns 31 is equipped with a receiving unit 2, and the other support column 31 is a telescopic structure with a rotating rod 32 at its top. The rotating rod 32 is connected to an angle conversion device 5, which can drive the rotating rod 32 to rotate 0°-90° around the top of the support column 31. The 0° state is a horizontal detection mode with horizontal beams, and the 90° state is a vertical detection mode with beams pointing downwards.

[0026] The angle conversion device 5 includes a drive motor 51 and a transmission shaft 52. The output end of the drive motor 51 is fixedly connected to the transmission shaft 52. The transmission shaft 51 is fixedly connected to the end of the rotating rod 32. The rotating rod 32 is hinged to the end of the support column 31. The transmission shaft 52 drives the rotating rod 32 to rotate around the top of the support column 31. The drive motor 51 is controlled by a control system to achieve automatic switching of the detection mode. The support column 31 connecting the rotating rod 32 includes a support column sleeve 311, a support inner tube 312, and a telescopic cylinder 313. The support column sleeve 311 is vertically fixed on the ground. The telescopic cylinder 313 is installed inside the sleeve. The output end of the telescopic cylinder 313 is fixedly connected to the support inner tube 312. One end of the support inner tube 312 is slidably disposed inside the support column sleeve 311.

[0027] The ground reflector 4 is laid on the lane surface directly below the transmitting unit 1 in vertical detection mode, and can be removed or stored in horizontal detection mode. The control system is electrically connected to the angle conversion device 5, the transmitting unit 1, and the receiving unit 3, and can receive mode switching commands and synchronously adjust the emission angle of the emitted beam and the signal acquisition parameters of the receiving unit.

[0028] Working principle: This remote sensing monitoring equipment mainly consists of a transmitting unit 1, a receiving unit 2, and a convertible support 3. The convertible support 3 includes support columns 31 positioned relative to the lane. The receiving unit 2 is fixedly installed on one support column 31, while the other support column 31 is a telescopic structure with a rotating rod 32 at its top. The rotating rod 32 is connected to the top of the support column 31 via an angle conversion device 5, allowing it to rotate 0°-90° around the top of the support column 31, thereby enabling the switching between two detection modes.

[0029] When vertical detection is required, the control system issues a vertical detection mode command, activating the drive motor 51 (part of the angle conversion device). This drives the rotating rod 32 via the transmission shaft 52 to rotate 90° around the top of the support column 31, placing the transmitting unit 1 in a vertically downward position. The telescopic cylinder 313 of the support column 31 adjusts the extension length of the inner support tube according to the lane height, aligning the transmitting unit 1 with the lane surface below. The transmitting unit emits a detection beam towards the lane surface below. A ground reflector 4 reflects the beam back, and the receiving unit 2 receives the reflected beam. By analyzing the exhaust gas information carried in the beam, the detection of vehicle exhaust gases is achieved.

[0030] When switching to horizontal detection mode is required, the control system issues a horizontal detection mode command, driving motor 51 to rotate in the opposite direction. This, via transmission shaft 52, drives rotating rod 32 to rotate to 0°. At this time, transmitting unit 1 and receiving unit 2 are positioned horizontally opposite each other on both sides of the vehicle lane. The telescopic cylinder 313 of the support column 31 adjusts the extension length of the inner support tube 312, ensuring that transmitting unit 1 and receiving unit 2 are at the same horizontal height. The transmitting unit emits a detection beam that passes through the lane to the receiving unit on the opposite side. As the beam passes through the vehicle exhaust, it carries information about the exhaust composition. Receiving unit 2 receives the beam and analyzes the information to detect the vehicle exhaust emissions.

[0031] The drive motor 51 in the angle conversion device 5 is controlled by the control system. When a mode switching command is received, the control system controls the rotation direction and angle of the drive motor according to the command, driving the rotating rod 32 to rotate via the transmission shaft 52, thereby switching the detection mode. During the switching process, the control system simultaneously adjusts the beam emission angle of the transmitting unit and the signal acquisition parameters of the receiving unit to adapt to the detection requirements of different detection modes and ensure the accuracy and stability of the detection. For example, in the vertical detection mode, the beam emission angle of the transmitting unit is vertically downward, and the signal acquisition parameters of the receiving unit are set according to the characteristics of the beam reflected by the reflector; in the horizontal detection mode, the beam emission angle of the transmitting unit is horizontal, and the signal acquisition parameters of the receiving unit are adjusted according to the characteristics of the beam passing horizontally through the lane.

[0032] This utility model provides a remote sensing monitoring device for motor vehicle exhaust emissions that converts vertical to horizontal modes. Through a convertible bracket and angle conversion device, it achieves automatic switching between vertical and horizontal detection modes without requiring equipment replacement. This adaptability to different detection scenarios and lane conditions significantly improves the device's flexibility and applicability. The support column features a telescopic structure, which, together with the rotating rod and angle conversion device, allows adjustment of the position and angle of the transmitting and receiving units according to the height and width of the lane, meeting the detection needs of lanes of different specifications and reducing dependence on specific installation environments. The control system is electrically connected to the angle conversion device, transmitting unit, and receiving unit, enabling synchronous adjustment of the emitted beam angle and signal acquisition parameters of the receiving unit during mode switching. This ensures accurate exhaust emission data acquisition in different detection modes, improving detection accuracy and reliability. Simultaneously, the automatic mode switching saves manual operation time and improves detection efficiency. The ground reflector is laid on the lane surface directly below the transmitting unit in vertical detection mode and can be detached or stored in horizontal detection mode, avoiding the reflector's impact on the lane during horizontal detection and facilitating its maintenance and management.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
