This device is designed as a road truck anti-overload system based on displacement sensors, integrating communication with various functional modules and multiple sensors.

[0033] The present embodiment provides a road truck anti-eccentric loading device, comprising a laser displacement sensor 1, a single-chip control system 2, an audible and visual alarm 3, a liquid crystal display screen, and a fixing device; the single-chip control system 2 is connected to the laser displacement sensor 1, the audible and visual alarm 3, and the liquid crystal display screen respectively; the laser displacement sensor 1 is installed between the truck frame 5 and the axle 6 through a fixing device, symmetrically distributed near the leaf spring 7, connected to the single-chip interface, and transmits the detected distance parameters to the single-chip in real time through data communication; the audible and visual alarm 3 and the liquid crystal display screen are connected to the single-chip, and when the truck body tilts more than 10°, an early warning is issued to prompt the driver to correct the vehicle and cargo status and control the vehicle to slow down; a 5V DC power supply is used to power the single-chip control system 2. The device of the present embodiment is easy to install, has a simple structure, is sensitive to cargo eccentric loading, and has a reliable accuracy.

[0034] This embodiment consists of a laser displacement sensor 1, a single-chip control system 2, an audible and visual alarm 3, a liquid crystal display screen, and a sensor fixing structure; the laser displacement sensor 1 can deduce the inclination angle of the object by measuring the displacement of the object in different directions; the single-chip control system 2 is respectively connected to the laser displacement sensor 1, the audible and visual alarm 3 and the LCD display screen 4 interface; the laser displacement sensor 1 is installed between the truck frame 5 and the axle 6 through a fixed structure, symmetrically distributed close to the leaf spring 7, the laser displacement sensor 1 is connected to the single-chip interface, and the detected distance parameters are transmitted to the single-chip in real time through data communication; the audible and visual alarm 3 and the liquid crystal display screen are connected to the single-chip pins; a 5V DC power supply is used to power the single-chip.

[0035] The single-chip control system 2 is installed under the rear berth of the truck cab. The overload threshold can be set according to the type of vehicle, triggering the sound and light alarm 3 to remind the driver or staff. The LCD display screen 4 is set in the cab of the truck body, installed above the instrument panel, facing the driver; the data line and control pin of the LCD display screen 4 are connected to the GPIO pin of the single-chip control system 2 to receive information and display the current status information of the vehicle body in real time. The sensor fixing structure is matched with a screw 9, a nut 10, and a steel plate 8. The laser displacement sensor 1 is fixed on the axle 6 without destroying the load-bearing system of the truck body, and the distance between the laser displacement sensor 1 and the axle 6 is adjusted according to the vehicle type and the accuracy range of the laser displacement sensor 1. The single-chip control system 2 connects to the CAN bus to notify the vehicle's ECU and dynamic control system to perform deceleration or other control operations.

[0036] The working process of this embodiment is specifically as follows:

[0037] As attached Figure 3 As shown, the laser displacement sensor 1 is installed between the truck frame 5 and the axle 6. Taking a two-axle light truck as an example, four laser displacement sensors 1 are symmetrically distributed, and the laser emission ports are in the same horizontal plane, which can monitor the distance change between the frame 5 and the axle 6 in real time. The laser displacement sensor 1 is connected to the analog input pin (AIN0 or AIN1) of the single-chip control system 2, and the detected distance data is sent to the single-chip control system in real time to monitor the tilt state of the vehicle in real time. Through the calculation of the single-chip algorithm, when the tilt angle of the truck body exceeds 10° or the center of gravity of the cargo in the compartment changes significantly, the early warning device is activated.

[0038] Connect the vehicle's ECU and dynamic control system to the microcontroller control system 2 using the CAN bus communication protocol or other appropriate communication protocols. Connect the CAN bus communication lines (CANH and CANL) to the corresponding pins of the CAN transceiver, connect the SPI interface (SCK, MISO, MOSI) of the CAN transceiver to the SPI pins of the microcontroller control system 2, connect the CS pin of the CAN transceiver to the GPIO pin of the microcontroller control system 2 for chip select for SPI communication, and connect the INT pin of the CAN transceiver to the GPIO pin of the microcontroller control system 2 to detect CAN messages. The microcontroller control system 2 continuously reads the data of the tilt sensor and triggers the system response according to the tilt state of the vehicle. If the tilt angle reaches a dangerous threshold, an audible alarm can be issued or the vehicle's ECU and dynamic control system can be notified through the CAN bus to perform deceleration or other control operations.

[0039] As attached Figure 2As shown, the sound and light alarm 3 is installed in the cab of the truck body, on the ceiling above the co-pilot, in an inverted manner; the sound and light alarm 3 is matched with the GPIO pin of the single-chip control system 2. When the early warning device starts the signal, the light flashes and the intermittent alarm sounds to remind the driver to check the tilt state of the vehicle in time and whether the cargo stacking position is reasonable.

[0040] As attached Figure 2 As shown, the LCD display screen 4 is installed in the cab, and the data lines (D0-D7) and control pins (RS, RW, EN) of the LCD display screen 4 are connected to the GPIO pins of the single-chip microcomputer control system 2, so as to realize the user interface single-chip microcomputer receiving the distance information of the laser displacement sensor 1, and the information such as the deviation distance of both sides of the vehicle body and the front and rear of the vehicle compartment, the center of gravity position of the cargo, etc. are displayed on the LCD display screen 4 for the driver's reference.

[0041] As attached Figure 4 As shown, the installation of the laser displacement sensor 1 does not cause damage to the light truck itself. First, the laser displacement sensor 1 is fixed on the steel plate 8, and then the steel plates 8 on the upper and lower sides of the axle 6 are fixed by U-bolts composed of screws 9 and nuts 10, which is convenient for installation and disassembly.

[0042] The present embodiment is a device for preventing over-biased loading of trucks. The laser displacement sensor 1 is installed between the axle 6 and the frame 5, and is symmetrically distributed near the inner side of the leaf spring 7. It can monitor the distance between the axle 6 and the frame 5 in real time. The single-chip microcomputer receives the sensor distance information. When the tilt angle of the truck body exceeds 10° or the center of gravity of the cargo in the compartment changes significantly, the sound and light alarm device is activated. The driver can correct the loading status of the truck in time according to the information on the display screen to avoid accidents and property losses of the cargo.

[0043] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
