[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] See also Figure 1-5 The present invention provides a technical solution for an integrated anti-collision warning device: the integrated anti-collision warning device includes an explosion-proof housing 2 and a touch screen display 3. The rear side of the touch screen display 3 is connected to a multi-in-one busbar 5. The multi-in-one busbar 5 adopts an aviation plug design and integrates a power supply line, an alarm connection line, and a relay output control line. The present invention simplifies the external connection line, facilitates installation and use, and adopts an aviation plug with the characteristics of waterproof, dustproof, and vibration resistance, thereby improving the reliability of the line connection.

[0038] The touch screen 3 is installed on the inside of the explosion-proof shell 2 and fixed by bolts, which is convenient for the disassembly and assembly of the touch screen 3. The explosion-proof shell 2 is used to fix and protect the internal circuit of the touch screen 3, and the back shell of the touch screen 3 is also provided with a heat sink; the touch screen 3 is used to realize human-computer interaction of alarm setting, alarm prompt and parameter setting, and the touch screen 3 is a high-defense touch screen. The user completes the early warning display and parameter setting through touch operation, and the high-defense touch screen has functions such as alarm setting and alarm prompt. The user can perform early warning display and parameter setting through touch operation to realize human-computer interaction. The display screen adopts high-brightness and high-contrast material, and can still clearly display information in strong light and harsh environment. The explosion-proof shell 2 can adopt but is not limited to stainless steel with a thickness of 3-5mm.

[0039] The middle parts of both sides of the explosion-proof housing 2 are connected to the mounting and adjusting base 1 in a common rotation. A connecting shaft 11 is provided between the two ends of the mounting and adjusting base 1 and the two side surfaces of the explosion-proof housing 2. An adjusting arc groove 12 is provided on the surface of both ends of the mounting and adjusting base 1 with the connecting shaft 11 as the center. A plurality of positioning screw holes 21 are arranged in an arc-shaped array on the two side surfaces of the explosion-proof housing 2 corresponding to the adjusting arc groove 12;

[0040] During the above adjustment: the two ends of the mounting adjustment seat 1 are rotatably connected to the explosion-proof housing 2 through the connecting shaft 11, and the bolts are passed through the adjusting arc groove 12 and screwed into the corresponding positioning screw holes 21 to achieve the fixation of the two. The middle part of the mounting adjustment seat 1 is provided with a threading hole and a bolt hole, which is convenient for fixing on mobile equipment such as forklifts, AGVs, and engineering machinery by bolts. Moreover, after the installation is completed, the angles of the explosion-proof housing 2 and the touch screen 3 can be conveniently adjusted through the connecting shaft 11, so that after installation, the angles can be adjusted, which is more convenient for the staff to operate. After the adjustment is completed, the two screws are directly screwed into the positioning screw holes 21 on both sides of the explosion-proof housing 2 to achieve fixation;

[0041] The front side of the explosion-proof housing 2 is provided with an anti-collision component for protecting the touch display screen 3, and the anti-collision component includes an anti-collision frame 4 hinged to the top of the front side of the explosion-proof housing 2 by a hinge 41, and a card strip 42 is fixed to the other end of the anti-collision frame 4. A card slot 22 is provided at the lower end of the front side of the explosion-proof housing 2 corresponding to the card strip 42. The size of the card strip 42 is adapted to the size of the card slot 22, and a magnetic piece is installed on one side of the card strip 42 corresponding to the card slot 22 and the inner bottom of the card slot 22, and the magnetic properties of the relative surfaces of the magnetic pieces on the card strip 42 and the card slot 22 are opposite. The top of the anti-collision frame 4 is hinged to the explosion-proof housing 2 by a hinge 41, and the anti-collision frame 4 is hinged to the explosion-proof housing 2. The other end of the frame 4 is inserted into the card slot 22 through the card strip 42 and fixed by the two magnets. When the staff needs to operate the touch screen 3, they directly pull the bottom of the anti-collision frame 4 to remove the card strip 42 from the card slot 22, and then flip the anti-collision frame 4 to expose the screen of the touch screen 3, which is convenient for setting parameters or operating instructions. After the operation is completed, the anti-collision frame 4 is flipped back to reset, so that the card strip 42 is inserted into the card slot 22 and fixed by the magnetic sheet. The anti-collision frame 4 can be fixed to the front side of the explosion-proof housing 2, so that the screen of the touch screen 3 can be protected to avoid collision or damage to the touch screen 3 during operation.

[0042] The explosion-proof housing 2 also has a built-in MCU algorithm processing module, data storage module, UWB ranging chip module, power module, network communication module and relay signal output control module. Among them, the UWB ranging chip module adopts UWB omnidirectional warning technology, which can achieve 360° all-round high-precision ranging, real-time monitoring of the surrounding environment, long detection distance and high ranging accuracy, and its ranging error can be controlled within the centimeter level;

[0043] Furthermore, the MCU algorithm processing module can analyze and process the data obtained by the UWB ranging chip module, and determine whether to trigger an alert based on the preset multi-level anti-collision warning distance settings. In addition, the module uses a high-performance processor and can adopt the STM32 series microcontroller with fast computing speed to ensure real-time processing and analysis of data.

[0044] Among them, the multi-level collision warning distance setting includes level 1 warning, level 2 warning and level 3 warning, which correspond to different distance ranges and relative speeds and trigger different warning methods, for example:

[0045] The device is installed on a forklift. If a person carrying a UWB tag enters the warning area around the forklift, the device uses the UWB ranging chip module to obtain the distance and relative speed between the person and the forklift in real time.

[0046] When a person enters the first-level warning area (i.e., 10-20 meters away from the forklift and the relative speed is less than 5 km / h), the touch screen will display a warning message, and the device will emit a slight beep and the light will flash;

[0047] When a person enters the secondary warning area (5-10 meters away from the forklift, with a relative speed of 5-10 km / h), the device emits a rapid beep, flashes a strong light, and vibrates strongly, and the warning message on the touch screen turns red and flashes;

[0048] When a person enters the third-level warning area (less than 5 meters away from the forklift and the relative speed is greater than 10km / h), the device not only issues a strong warning, but the relay signal output control module also outputs control instructions to control the forklift's braking system, causing the forklift to slow down and stop, and at the same time uploads the alarm information to the background management system.

[0049] Furthermore, when the warning is triggered, the relay signal output control module can output a control command to control the vehicle braking, and can also be connected to an external alarm to provide sound, light or voice alarm prompts, ensuring that the device can act quickly in an emergency;

[0050] The network communication module can upload alarm data to the system platform to achieve remote monitoring and management, and supports multiple network protocols such as Ethernet and Wi-Fi to ensure the stability and timeliness of data transmission. The data storage module is used to store alarm records for subsequent query and analysis. Its large storage capacity can save alarm data for a long time, and it has a data backup function to prevent data loss.

[0051] The power module provides stable power support for the entire device. The input voltage is DC12V and it has overvoltage, overcurrent, and short-circuit protection functions to ensure safe and reliable operation of the device.

[0052] In addition, the device can be expanded to include alarms, electronic brake controllers, surveillance cameras and other equipment.

[0053] The working principle of the present invention is as follows: when in use, the device is fixed to a mobile device such as a forklift, AGV, or construction machinery by using the combination of bolts and the mounting adjustment base 1, and then the angles of the explosion-proof housing 2 and the touch screen 3 are adjusted to an angle that is convenient for operation;

[0054] Furthermore, the anti-collision frame 4 is opened, and the staff sets and adjusts the parameters of the device through the touch screen 3. After the adjustment is completed, the anti-collision frame 4 is reset and fixed to the front side of the explosion-proof housing 2, which is convenient for protecting the screen of the touch screen 3 during use to avoid damage to the screen due to collision;

[0055] When used, the device conducts real-time high-frequency detection and identification with targets carrying UWB tags. The detection frequency can be adjusted according to actual needs, up to dozens of times per second.

[0056] During use, the early warning device will use the received detection information to calculate the distance through relevant algorithms. The calculation process is fast and accurate, ensuring timely acquisition of the distance information between the target and the device. Then, based on the acquired distance information, comparison, judgment and graded warning are carried out, as follows:

[0057] Level 1 warning (reminder): When a target enters the warning area, due to the target's large distance and relatively low speed, a gentle prompt will be issued, such as flashing lights and slight beeps, to draw attention.

[0058] Level 2 warning (warning): When the target enters the danger zone, due to the decrease in distance and the high relative speed of the target, a strong warning will be issued, such as rapid beeps, strong flashing lights, and strong vibrations.

[0059] Level 3 warning (emergency braking / avoidance): When a collision with a target is imminent, in addition to a strong warning, the device's system will trigger automatic deceleration and braking functions.

[0060] In addition, when the above-mentioned warning is triggered again, the corresponding warning information will be transmitted to the operator and relevant personnel through sound, light, vibration, screen display, etc., and uploaded to the background management system for record, so as to facilitate subsequent data analysis and accident tracing.

[0061] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
