Description

Technical Field

[0001] This invention relates to an auxiliary device for airport boarding bridges, and to a rearview mirror device and method for displaying the connection status of a bridge-mounted static power supply. Background Technology

[0002] In current airport operations, crew members rely on manual communication or voice confirmation with ground personnel via headsets, or on-board power status lights, to perceive the status of bridge-mounted power supplies. These methods suffer from problems such as information asymmetry, lack of visualization, susceptibility to misjudgment, and significant differences in standardization.

[0003] Reference patent CN105549517A discloses a boarding bridge and a remote monitoring device for bridge-mounted equipment based on flight information. Although it has the functions of remote monitoring and equipment status assessment, it lacks real-time visual prompts and does not solve the problem of intuitive information transmission between the crew and the boarding bridge.

[0004] In addition, reference patent CN120181324A discloses a critical flight identification and support plan reverse scheduling method based on LTOT, which mainly focuses on intelligent monitoring and resource optimization of flight status, but fails to directly solve the need for real-time and intuitive display of bridge-mounted power connection status.

[0005] Therefore, the existing technology lacks a system that can provide an instant and intuitive connection status indication for bridge-mounted static transformers to enhance the crew's ability to identify the working status of bridge-mounted static transformers, improve the efficiency of maintenance coordination, and reduce communication dependence and the risk of misoperation.

[0006] To address these technical issues, this application proposes a static variable power supply connection status indication system integrated into the rearview mirror structure of the boarding bridge control panel, aiming to provide a visual, real-time indication solution to solve the aforementioned problems. Summary of the Invention

[0007] The purpose of this invention is to provide a multi-state display rearview mirror device, method, and application for bridge-mounted static power supply connection status, in order to solve the problems of unintuitive information transmission, low communication efficiency, and high risk of operational misjudgment between current airport boarding bridges and aircraft crews regarding ground power supply connection status.

[0008] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0009] To solve the above-mentioned technical problems, the present invention is implemented using the following technical solution: A rearview mirror device for displaying the connection status of a bridge-mounted static transformer power supply includes a mounting bracket. It is characterized by further including a rearview mirror assembly, which comprises a rearview mirror, an LED status display module, and a control unit. The control unit includes an MCU control module, a status acquisition circuit, and a drive module. The MCU control module is externally connected to a GPU control unit and a ground-based main control system. It receives the bridge-mounted static transformer power supply connection status signal output by the GPU, determines the current power supply status through internal logic, and retrieves pre-stored text dot matrix data from internal or external memory. The text dot matrix data is output to the drive module via the MCU control module, where it undergoes signal conditioning and current driving before being transmitted to the LED status display module.

[0010] Furthermore, the LED status display module has dimensions of 414*222*55mm, a resolution of 800*480 pixels, and a brightness of not less than 5000 cd.

[0011] Furthermore, the LED status display module is located on the back of the rearview mirror, facing the pilot, so that the pilot can observe and obtain the connection status and power supply status between the ground static power supply and the aircraft.

[0012] Furthermore, the MCU control module is connected to the status signal line of the ground static power supply through its IO interface, and can read the high and low level signals output from the static power supply in real time.

[0013] Furthermore, different level combinations correspond to different operating states, including: a high level indicates that the power is connected, and a low level indicates that the power is not connected and is in a waiting state.

[0014] Furthermore, the LED status display module's display screen intuitively displays three status information in a dot matrix format: "Ground power waiting," "Ground power connected," and "Ground power supply in progress."

[0015] Furthermore, PoE (Power over Ethernet) or traditional power supply modes can be adopted.

[0016] Furthermore, the rearview mirror device for displaying the connection status of the bridge-mounted static transformer power supply is protected by: control signal isolation, reverse connection protection, voltage protection, and IP65 enclosure protection. The rearview mirror device displaying the connection status of the bridge-mounted static power supply is fixed to the outer frame of the airport boarding bridge access gate via a mounting bracket.

[0017] A method for displaying the connection status of the bridge-mounted static transformer power supply using a rearview mirror display device includes: The MCU control module is connected to the GPU control unit and the ground main control system. It receives the connection status signal of the bridge-mounted static transformer output by the GPU, and displays the current connection status of the bridge-mounted static transformer through internal logic operation and output drive via the LED status display module. The LED status display module's screen displays three status messages in a dot matrix format: "Ground power waiting," "Ground power connected," and "Ground power supply in progress," allowing operators to quickly ascertain the ground power connection and supply status.

[0018] Application of a bridge-mounted static power supply connection status display rearview mirror device, wherein the bridge-mounted static power supply connection status display rearview mirror device is used to indicate the electrical connection status between the airport boarding bridge and the aircraft.

[0019] Compared with the prior art, the beneficial effects of the present invention are: 1. When the aircraft bridge is separated from the aircraft, the bridge-mounted static power supply usually needs to be turned off. However, in actual work, sometimes it is forgotten to turn it off; or when the aircraft is parked at the airport boarding bridge, the static power supply cannot be turned off due to avionics system failure.

[0020] This invention can promptly remind the crew of the connection status of the bridge-mounted static transformer, thus avoiding potential electrical safety hazards during service. 2. It solved the problem of poor information transmission between airport boarding bridges and aircraft.

[0021] Previously, this process mainly relied on telephone communication or broadcasting to transmit information, which was prone to deviations or inaccurate misunderstandings, thus delaying passengers' travel time.

[0022] This invention can provide real-time feedback on the connection status of the bridge-mounted static transformer to the generator crew, effectively improving service efficiency. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this invention. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this invention, and should not be construed as limiting the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention. The embodiments of this invention will be described in detail below with reference to the accompanying drawings.

[0025] In the description of this invention, it should be understood that the terms "center", "longitudinal", "lateral", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this invention.

[0026] The present invention will now be described in detail with reference to the accompanying drawings: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a rearview mirror device for displaying the connection status of a bridge-mounted static transformer is used to indicate the electrical connection status between an airport boarding bridge and an aircraft, thereby improving service quality and efficiency.

[0027] A rearview mirror device for displaying the connection status of a bridge-mounted static transformer includes a mounting bracket and a rearview mirror assembly; the rearview mirror assembly includes an outer frame, a rearview mirror, an LED status display module, and a control unit. The rearview mirror device for displaying the connection status of the bridge-mounted static transformer is fixed to the outer frame of the airport boarding bridge's arrival port by a mounting bracket. When operating the boarding bridge, the operator can observe the position of the boarding bridge's wheels through the rearview mirror mounted on the side facing the operator for easier operation. This is the original basic function of the boarding bridge's rearview mirror. The LED status display module measures 414*222*55mm, with a resolution of 800*480 pixels and a brightness of no less than 5000 cd, suitable for outdoor use. Located on the back of the rearview mirror, facing the pilot, the module allows the pilot to observe the connection and power supply status between the ground static power supply and the aircraft, facilitating appropriate operations by the crew (such as switching the aircraft's power supply to external power as needed). The connection status of the bridge-mounted static power supply can be viewed through this rearview mirror device.

[0028] The control unit is installed inside the rearview mirror assembly and includes an MCU control module, a status acquisition circuit, and a drive module.

[0029] The MCU control module connects to the GPU control unit and the ground main control system. It receives the connection status signal of the bridge-mounted static transformer from the GPU output. Through internal logic operations and output driving, it displays the current connection status of the bridge-mounted static transformer through the LED status display module. The LED status display module obtains the display information through the control module. The control module obtains signals from the control unit of the ground static transformer (external equipment). Specifically, there is a set of signal lines on the power plug, and the signals "power plug connected" and "powering on" are returned to the GPU control unit of the ground static transformer through this set of signal lines. The control unit intercepts the "connected" and "powering on" signals at the corresponding terminals inside the power supply. After obtaining the corresponding signals, the control module sends the corresponding display information ("Ground power connected" "Ground power supply is supplying power") to the LED status display module to display the corresponding information. When the "Ground power connected" signal is displayed, a ring of lights is also displayed on the LED display screen to more prominently remind several groups of personnel.

[0030] like Figure 6As shown, this invention provides an LED status display method based on MCU control, specifically a method for displaying the connection status of a bridge-mounted static power supply on a rearview mirror device. The MCU control module is connected to the status signal line of the ground static power supply through its multi-channel I / O interface, enabling real-time reading of high and low level signals output from the static power supply. Different level combinations correspond to different operating states, including: a high level indicating that the power supply is connected, and a low level indicating that the power supply is not connected or in a waiting state.

[0031] After receiving the corresponding signal, the MCU control module determines the current power status through its internal logic and retrieves pre-stored text dot matrix data from internal or external memory. The text dot matrix data is output from the MCU control module to the driver module, which performs signal conditioning and current driving before transmitting it to the LED status display module.

[0032] Ultimately, the LED status display module's screen displays three status messages in a dot matrix format: "Ground power waiting," "Ground power connected," and "Ground power supply in progress," enabling operators to quickly ascertain the ground power connection and supply status.

[0033] This invention can be powered by a traditional power supply or extended to PoE (Power over Ethernet) mode. Using PoE offers advantages such as convenient network expansion, reduced equipment costs, and simplified cabling.

[0034] Device protection: control signal isolation, reverse connection protection, voltage protection, IP65 enclosure protection.

The rearview mirror device for displaying the connection status of a bridge-mounted static power supply is used to indicate the electrical connection status between an airport boarding bridge and an aircraft.
