[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0034] In the existing technology, when constructing underground tunnels, it is necessary to transport materials by flatbed trucks traveling on unlaid tracks. However, due to the limited construction range in the tunnel, it is difficult for the locomotive head to pull the flatbed truck to turn around in the track, and it often happens that the locomotive head pushes the flatbed truck behind the direction of travel of the flatbed truck. When the locomotive head is behind the direction of travel of the flatbed truck, due to the large number of mounted flatbed trucks, there is a large distance between the frontmost flatbed truck and the locomotive head where the driver is located. Therefore, it is difficult for the driver to grasp the road conditions in front of the flatbed truck in real time, and collision accidents are prone to occur during the travel process.

[0035] Reference Figure 1 and Figure 2 In order to overcome the problem that the driver cannot clearly know the road condition in front of the flatbed when there are many vehicles mounted on the flatbed, the embodiment of the present application provides a vehicle-mounted navigation device. The vehicle-mounted navigation device provided by the present application includes: an image acquisition module 10, an image recognition module 20, a temperature acquisition module 30, a temperature judgment module 40, a control module 50 and an alarm module 60.

[0036] The image acquisition module 10 is installed in front of the frontmost flatbed vehicle in the direction of travel. The image acquisition module 10 is configured to collect image data in front of the flatbed vehicle.

[0037] Exemplarily, the image acquisition module 10 may include a camera, which is fixed to the front of the flatbed truck body in the direction of travel by bolt connection, and obtains the road conditions in front of the flatbed truck and the image of construction workers near the track through its own image acquisition port.

[0038] The image recognition module 20 is communicatively connected to the image acquisition module 10 via an HDMI cable or a USB cable. The image recognition module 20 is configured to recognize whether there is a person image in the image data.

[0039] Exemplarily, the image recognition module 20 can be set to NVIDIA AI module Jetson Nano or Huawei AI module Atlas 200. The image recognition module 20 uses the YOLO target detection algorithm to detect whether there are construction workers in the image data, and processes the image data through a binary method to separate the construction worker image from the track image, thereby knowing whether there are construction workers within the track range.

[0040] The image acquisition module 10 obtains the road condition information ahead in the direction of travel of the front flatbed truck, thereby reducing the driver's blind spot during the movement of the flatbed truck. At the same time, the image acquisition module 10 transmits the impact data to the image recognition module 20. The image recognition module 20 uses the image recognition algorithm to recognize the image of the person within the track range in the image data, so that the driver can know in advance whether there is a collision risk in the track ahead of the flatbed truck.

[0041] The temperature acquisition module 30 is configured to collect temperature data in front of the flatbed vehicle. The temperature acquisition module 30 includes a thermal imaging probe or a temperature sensor, which is used to collect temperature data in front of the flatbed vehicle and transmit the temperature data to the temperature judgment module 40.

[0042] The temperature determination module 40 is communicatively connected to the temperature acquisition module 30 via a communication line. The temperature determination module 40 is configured to receive temperature data collected by the temperature acquisition module 30 and determine whether the corresponding temperature data is greater than a preset threshold.

[0043] The preset threshold is obtained by the staff according to the climate conditions at the construction site and the detection accuracy of the temperature acquisition module 30. The preset threshold can represent the ambient temperature at the construction site.

[0044] Exemplarily, the temperature judgment module 40 can be implemented as a temperature comparator circuit, which includes at least two input terminals and one output terminal, wherein one input terminal is used to connect to the temperature acquisition module 30, and the other input terminal is used for the user to input a preset threshold value, and the output terminal is communicated with the control module 50.

[0045] When the ambient temperature collected by the temperature acquisition module 30 is greater than the preset threshold, it indicates that there are other heat sources in the environment. The temperature judgment module 40 determines whether the temperature data is greater than the preset threshold, and transmits the corresponding result to the control module 50, thereby assisting the driver to determine whether there are people in front of the flatbed truck in the direction of travel, so as to reduce the occurrence of collision accidents.

[0046] The control module 50 is connected to the image recognition module 20 and the temperature determination module 40 through network cables; the control module 50 can be implemented as a single-chip microcomputer controller.

[0047] The control module 50 is configured to: receive a first signal sent by the image recognition module 20 when the image recognition module 20 recognizes a person image; receive a second signal sent by the temperature judgment module 40 when the temperature judgment module 40 determines that the temperature data is greater than a preset threshold, and output a control signal from its own output end after receiving the first signal or the second signal.

[0048] The alarm module 60 is in communication connection with the control module 50 . The alarm module 60 is installed in the cab of the locomotive head by bolt fixing. The alarm module 60 is configured to receive the control signal transmitted by the control module 50 and issue a warning message.

[0049] Exemplarily, the alarm module 60 may include an audible and visual alarm or a buzzer. The control end of the alarm module 60 is communicatively connected to the output end of the control module 50, and is used to receive the control signal transmitted by the control module 50 and issue a sound and light warning message or a buzzer.

[0050] By setting an image acquisition module 10 and a temperature acquisition module 30 in the direction of travel of the flatbed truck, the image acquisition module 10 acquires image data in the direction of travel of the flatbed truck, and the image recognition module 20 judges the image data to identify whether there is a person in the image data, and transmits the recognition result as the first information to the control module 50; at the same time, the temperature acquisition module 30 acquires temperature data near the flatbed truck, and the temperature judgment module 40 determines whether the temperature data acquired is greater than a preset temperature threshold, and transmits the judgment result as the second information to the control module 50, and the control module 50 sends a control signal to the alarm module 60, and causes the alarm module 60 to send an alarm message. The present application effectively solves the problem in the prior art that it is difficult for the driver to clearly know the road conditions in front of the flatbed truck when the number of flatbed trucks mounted is large, and achieves the purpose of reducing the blind spot of the flatbed truck during the travel and providing early warning information to the driver.

[0051] In some embodiments, in order to further facilitate the driver to obtain the image in front of the flatbed truck in real time, the vehicle-mounted navigation device provided in the present application also includes a display 70, which is installed in the cab of the front of the locomotive. The display 70 is communicatively connected to the image acquisition module 10 via an HDMI cable or a USB cable. The display 70 is configured to receive the image data collected by the image acquisition module 10 and display the image data on its own screen.

[0052] The driver in the locomotive cab can obtain the track information in front of the flatbed truck in real time through the picture displayed on the screen of the display 70, which further facilitates the driver to grasp the movement of the flatbed truck and reduces the probability of collision of the flatbed truck during movement.

[0053] In some embodiments, in order to improve the reliability of the vehicle-mounted navigation device provided by the present application, the embodiment of the present application further includes a power supply module 80. The power supply module 80 provided by the present application is electrically connected to the power interfaces of the image acquisition module 10, the image recognition module 20, the temperature acquisition module 30, the temperature judgment module 40, the control module 50 and the alarm module 60 through wires. The power supply module 80 is used to supply power to the image acquisition module 10, the image recognition module 20, the temperature acquisition module 30, the temperature judgment module 40, the control module 50 and the alarm module 60. The power supply module 80 can be implemented as a vehicle-mounted battery or a UPS power supply.

[0054] In some embodiments, in order to improve the applicability of the vehicle-mounted navigation device, the vehicle-mounted navigation device provided in the present application also includes a data storage module 90. The data storage module 90 can be implemented as a mobile hard disk. The data storage module and the control module 50 are communicatively connected via a USB cable. The data storage module is used to store the first signal sent by the image recognition module 20 and the second signal sent by the temperature judgment module 40.

[0055] The remaining modules of the vehicle-mounted navigation device are powered by the energy supply module 80, and the first signal sent by the image recognition module 20 and the second signal sent by the temperature judgment module 40 are stored by the data storage module 90 to facilitate the subsequent evaluation of the usage status of the vehicle-mounted navigation device and reduce the probability of misjudgment of the vehicle-mounted navigation device.

[0056] In the embodiment of the present application, an image acquisition module 10 and a temperature acquisition module 30 are set in the direction of travel of the flatbed truck. The image acquisition module 10 acquires image data in the direction of travel of the flatbed truck, and the image recognition module 20 judges the image data to identify whether there is a person in the image data, and transmits the recognition result as the first information to the control module 50; at the same time, the temperature acquisition module 30 acquires temperature data near the flatbed truck, and the temperature judgment module 40 determines whether the temperature data acquired is greater than a preset temperature threshold, and transmits the judgment result as the second information to the control module 50, and the control module 50 sends a control signal to the alarm module 60, and causes the alarm module 60 to send an alarm message.
