DETAILED DESCRIPTION

[0023] The technical scheme and technical effects of the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings of the present invention.

[0024] Please see Figures 1 to 3 A special motor vehicle slope detection device for factory use includes a test host and an operating host 20 wirelessly connected to the test host; the test host includes a front plate 110, a rear plate 120 and a host shell 130, the front plate 110 is embedded with a power switch 111 and a charging socket 112, the rear plate 120 is embedded with a GNSS measurement module 121 and a wireless transmission module 122, and the front plate 110 and the rear plate 120 are respectively fixed on the front and rear sides of the host shell 130.

[0025] The operating host 20 is used to send data collection instructions to the test host. The test host locates the vehicle through the GNSS measurement module during the vehicle's driving process, and obtains the vehicle's position information in real time. The test host then returns the acquired position information to the operating host for processing. The operating host calculates the height difference and horizontal distance of the vehicle at different positions, thereby calculating the slope of the vehicle's driving path. The utility model uses a high-precision GNSS measurement module to automatically calculate the slope in real time, thereby improving the stability of slope detection, reducing cumulative errors, and improving the accuracy of slope measurement, ensuring the safe operation of special motor vehicles in the factory.

[0026] In some embodiments, the power switch 111 is used to control the start and stop of the working mode of the test host, and the charging socket 112 is used to charge the test host. In some embodiments, a battery module is also installed inside the test host, and the battery module is used to power the test host, and the battery module is electrically connected to the charging socket to charge the battery module through the charging socket. In some embodiments, the GNSS measurement module 121 uses a GNSS antenna.

[0027] In some embodiments, a posture sensor is also provided inside the test host. The posture sensor includes a three-axis attitude angular velocity and an accelerometer for collecting the posture information of the vehicle during driving. By combining the position information measured by the GNSS measurement module with the posture information, more accurate slope data can be obtained.

[0028] Further, please refer again to Figures 1 to 3The four corners of the front plate 110 are respectively provided with screw holes, and the four corners of the rear plate 120 are respectively provided with screw holes. The front plate 110 and the rear plate 120 are fixed to the main body shell 130 by screws 300. The structure of the main body shell 130 is a shell with front and rear hollows. The front plate 110 and the rear plate 120 are respectively fixed to the front and rear sides of the main body shell 130 by screws 300, thereby forming a closed structure, and all the components of the test host are covered inside the main body shell, so as to protect the components of the test host.

[0029] Further, please refer again to Figures 1 to 3 , a magnet 400 is provided at the bottom of the host housing 130 to magnetically fix the test host to the dedicated motor vehicle in the factory. Specifically, the magnet 400 is fixed to the bottom of the host housing 130 by screws or magnetic attraction, and the magnets 400 are provided at the four corners of the bottom of the host housing 130 to ensure that the test host can remain horizontal when it is fixed to the dedicated motor vehicle in the factory by magnetic attraction, thereby ensuring that the test host can accurately obtain positioning information.

[0030] Furthermore, the wireless transmission module is a WiFi antenna, and the test host communicates using WiFi. Therefore, a WiFi module is also provided on the corresponding operation host, so that the operation host sends the data collection quality to the test host via WiFi, and the data collected by the test host is returned to the operation host via WiFi.

[0031] Furthermore, the slope detection device for in-plant motor vehicles of the utility model also includes an RTK receiving module, which is installed on the roof of the in-plant motor vehicle. RTK is a carrier phase differential technology, which is a differential method for real-time processing of carrier phase observations of two measuring stations, so that the three-dimensional positioning results of the measuring station in the specified coordinate system can be provided in real time, and the centimeter-level positioning accuracy can be achieved. Combining RTK can reduce the error between the GNSS measurement module and the satellite, further improve the accuracy and real-time performance of the measurement, and then calculate more accurate slope data.

[0032] For further information, see Figures 4 to 6, the RTK receiving module includes a signal receiving module 510, a mounting base 520 and a magnetic component 530, which are installed in sequence, and the magnetic component 530 is installed on the roof of a special motor vehicle in the factory, and the mounting base 520 is used to connect the signal receiving module 510 and the magnetic component 530. Specifically, the signal receiving module 510 serves as the base station of the RTK receiving module, and the GNSS measurement module receives signals from multiple satellites and records the observation data of each satellite, such as the receiving time, signal strength, etc. Then the GNSS measurement module sends the observation data to the base station, i.e., the signal receiving module 510. The base station uses its own high-precision position information and the received observation data to calculate the differential correction value, and sends the differential correction value back to the GNSS measurement module. The GNSS measurement module corrects its own position according to the received differential correction value, thereby obtaining accurate position information.

[0033] For further information, see Figure 7 The operation host 20 includes an operation control mainboard, a structural shell 210, and a display screen 220. The operation control mainboard is fixed inside the structural shell 210, and the display screen 220 is fixed outside the structural shell 210. The operation host 20 is the device control end. The instrument operation instructions are sent through the operation interface on the display screen 220. After receiving the operation instructions sent by the display screen, the operation control mainboard generates a data acquisition instruction and sends it to the test host. The test host controls the GNSS measurement module to measure the position information of the vehicle during driving, and returns the position information to the operation host. The operation host processes the position information to obtain the slope data. At the same time, the operation host can display the vehicle's driving trajectory and slope intuitively and visually on the display screen under the high-precision map using the acquired GNSS navigation information, position, attitude and other data.

[0034] In some embodiments, the operating host can be handheld and operated by the inspection personnel, or it can be installed on a special motor vehicle in the factory. For example, the operating host can be installed in the co-pilot seat and operated by the inspection personnel sitting in the co-pilot seat. The vehicle's driving trajectory, slope, and statistical relationship graphs between slope and distance can be viewed in real time during the vehicle's driving.

[0035] The above disclosure is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
