Description

Technical Field

[0001] This utility model relates to the field of automated logistics equipment technology, and in particular to a backpack AGV status display projection system. Background Technology

[0002] AGVs, or Automated Guided Vehicles, are battery-powered transport robots that use electromagnetic or photoelectric automatic guidance devices as their core. They can automatically travel along preset routes and integrate human-machine interaction, safety protection, and transport functions. They are widely used in logistics handling, flexible assembly lines, processing lines, and special applications. In today's rapidly developing automated warehousing and logistics industry, AGVs, as key equipment, are crucial for improving overall efficiency and safety through real-time monitoring and interactive operation.

[0003] Currently, during the operation of AGVs, status information is mainly presented through indicator lights and displays, covering working status, current task, location coordinates, and fault information. However, indicator lights can only provide simple information such as operating status, and displays are usually mounted on the side of the AGV, perpendicular to the ground. Due to the low height of the AGV, viewing it often requires bending over or even crouching, which not only makes it difficult to obtain information in a timely manner but also poses safety hazards.

The information acquisition unit is electrically connected to the control unit and is used to acquire the status information of the AGV and transmit the status information to the control unit. The control unit is electrically connected to the display unit and is used to receive the status information of the AGV and control the operation of the display unit. The display unit includes a projection device connected to the side of the AGV body and is used to project the status information of the AGV onto the working surface of the AGV in real time, forming a virtual display interface on the working surface.

[0005] Furthermore, the system also includes a motion sensing unit, which is electrically connected to the control unit and is used to receive the operator's actions in the virtual display interface area and transmit them to the control unit.

[0006] Furthermore, the system also includes a hardware switch for controlling the activation and deactivation of the motion sensing unit to lock or unlock the touchscreen function of the projection device.

[0007] Furthermore, the projection device is a DLP micro projector or a laser projector, and the motion sensing unit is an infrared detection device or a motion capture camera.

[0008] Furthermore, the display unit also includes a display, which is connected to the projection device via a high-speed data interface.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. This utility model's backpack-type AGV status display projection system can project the AGV's status information onto the AGV's working surface in real time via a projection device.

[0019] refer to Figures 1 to 2 As shown, this utility model discloses a backpack-type AGV status display projection system, including an information acquisition unit, a control unit 3, and a display unit. The information acquisition unit is electrically connected to the control unit 3 and is used to acquire the status information of the AGV and transmit the status information to the control unit 3. The control unit 3 is electrically connected to the display unit and is used to receive the status information of the AGV and control the display unit to work. The display unit includes a projection device 1, which is connected to the side of the AGV body 7 and is used to project the status information of the AGV onto the working ground 6 of the AGV in real time, forming a virtual display interface on the working ground 6.

[0020] This utility model's backpack-type AGV status display projection system can project the AGV's status information onto the AGV's working surface 6 in real time via the projection device 1. This allows operators to monitor key status information such as the AGV's battery level, speed, and task progress in real time, facilitating timely understanding of the AGV's working status and enabling appropriate decision-making. Simultaneously, the virtual display interface formed on the working surface 6 does not occupy the AGV's volume, thereby improving the AGV's space utilization rate.

[0021] In some embodiments, the projection device 1 is fixed to the side of the AGV body 7 near the top by an adjustable angle bracket to ensure that the projected image can be accurately projected onto the designated area of ​​the AGV's working ground 6, and the height of the projection device 1 is less than or equal to the height of the AGV body 7 to prevent collisions or other interference to surrounding equipment or personnel. Preferably, the projection device is a DLP micro projector or a laser projector.

[0022] In some embodiments, the display unit further includes a display 2, and the projection device 1 is connected to the display 2 via a high-speed data interface to achieve synchronous image output. The control unit 3 transmits the AGV's status information to the display unit, and the display 2 of the display unit displays the AGV's status information. Simultaneously, the projection device 1 projects this content onto the AGV's working surface 6, forming a clear, bright, and preset-sized virtual display interface. Preferably, the projection device 1 has a built-in ambient light sensor. Under different ambient lighting conditions, the projection device 1 can automatically adjust its brightness. By detecting the ambient light intensity in real time through the built-in ambient light sensor, it automatically adjusts the projection brightness to ensure that the projected image is clearly visible under both strong and weak light conditions.

[0023] In some embodiments, the backpack AGV status display projection system further includes a motion sensing unit 5, preferably an infrared detection device or a motion capture camera. The motion sensing unit 5 is electrically connected to the control unit 3 and is used to receive the operator's actions in the virtual display interface area and transmit them to the control unit 3.

[0024] In some embodiments, the motion sensing unit 5 is an infrared detection device. The infrared detection device is installed on the side of the AGV body 7 and is located on the same side as the projection device 1. The infrared detection device arranges infrared emitting tubes and receiving tubes around the projection area to form an infrared matrix, ensuring that the operation actions of human hands or specific tools in the touch screen area can be detected comprehensively and accurately. During installation, the infrared detection device maintains a predetermined angle and distance from the ground to avoid detection blind spots or misjudgments.

[0025] In some embodiments, the backpack AGV status display projection system also includes a hardware switch 4 for controlling the opening and closing of the motion sensing unit 5 to lock or unlock the touchscreen function of the projection device. The infrared detection device is connected to the hardware switch 4 via a microcontroller. When the hardware switch 4 is closed (unlocked state), the microcontroller receives a signal and activates the infrared detection device. The infrared emitter emits infrared signals at a set frequency, and the receiver monitors changes in the reflected signal in real time. Once an operation is detected, the analog signal is converted into a digital signal and fed back to the control unit 3 for further processing. When the hardware switch 4 is open (locked state), the microcontroller controls the infrared detection device to stop working, preventing accidental touches during normal AGV operation and reducing energy consumption.

[0026] In this embodiment, the backpack AGV status display projection system allows for direct interactive control of the AGV by simply unlocking the touchscreen function via hardware switch 4 when manual intervention is required. This enables gesture or tool clicks and swipes within the projection area, simplifying operation, reducing complexity, and improving work efficiency.
