Description

Technical Field

[0001] This invention relates to a wireless parameter setting system and method for aircraft, belonging to the field of aircraft control. Background Technology

[0002] Intelligent aircraft can perform different flight missions based on actual conditions. This requires flexible modification of some important parameters of the aircraft controller, making parameter setting before takeoff particularly important. Current data transmission methods include wired setting and wireless setting.

[0003] Traditional wired data binding processes are cumbersome, requiring frequent plugging and unplugging of cables, which affects binding efficiency and cannot meet the practical needs of batch binding and rapid transmission. Furthermore, the long cables also pose a risk of accidents.

[0004] The principle of wireless data binding is to use wireless communication technology to replace wired communication interfaces. However, currently common wireless data binding methods require power from the aircraft. Powering the aircraft controller before data binding not only poses certain risks but also adds to the data binding process, remaining cumbersome and complex. Furthermore, considering factors such as aircraft size and cost, current wireless power transfer technologies cannot meet the peak power consumption requirements of the aircraft controller. Summary of the Invention

[0005] The purpose of this invention is to overcome the aforementioned shortcomings and provide a wireless parameter binding system and method for aircraft, solving the technical problem that traditional wired data binding processes are cumbersome and cannot meet the practical needs of batch binding and rapid launch. This invention employs short-range wireless communication technology to communicate with ground-based equipment, receiving and storing mission binding parameters sent by the ground-based equipment, thereby achieving the goal of rapidly binding mission parameters through wireless communication technology without electrical interconnection with the carrier aircraft.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0007] An aircraft wireless parameter setting system includes: a power management module, a near-field wireless communication transceiver module, an MCU module, and an RS-422 transceiver module;

[0008] The power management module receives the voltage input from the aircraft controller or the near-field wireless communication transceiver module, performs DC / DC conversion on the voltage, and supplies power to the RS-422 transceiver module, the MCU module, and the near-field wireless communication transceiver module; the RS-422 transceiver module is used to realize the data transmission between the MCU module and the aircraft controller.

[0009] The near-field wireless communication transceiver module is used to realize the data transmission between the MCU module and the ground terminal, and at the same time, it is used to receive the voltage transmitted from the ground terminal and output the voltage transmitted from the ground terminal to the power management module.

[0010] The MCU module is used to receive the data to be bound from the near-field wireless communication transceiver module, store the data to be bound, and realize the wireless parameter binding of the aircraft by transmitting the data to the aircraft controller.

[0011] Furthermore, anti-reverse current diodes are connected in series at the voltage output terminals of the aircraft controller and the near-field wireless communication transceiver module, respectively.

[0012] Furthermore, the RS-422 transceiver module is used to convert the serial communication signal output by the MCU module into an RS-422 standard signal and output it to the aircraft controller, or to convert the RS422 standard signal output by the aircraft controller into a serial communication signal and output it to the MCU module.

[0013] Furthermore, the near-field wireless communication transceiver module receives voltage signals from the ground terminal and transmits data to be bound via near-field wireless communication.

[0014] Furthermore, the MCU module includes a normal operating mode and a low-power mode;

[0015] When the aircraft controller is powered on, it enters normal operating mode; when the aircraft controller is not powered on, it enters low power mode.

[0016] In normal operating mode, the MCU module receives the data to be bound from the near-field wireless communication transceiver module, stores the data, and performs wireless parameter binding of the aircraft by transmitting the data to the aircraft controller. In low-power mode, the MCU module receives the data to be bound from the near-field wireless communication transceiver module and stores the data.

[0017] Furthermore, the MCU module determines whether the aircraft controller is powered on by sampling the voltage at the power supply output terminal of the aircraft controller, or by sampling the voltage at the power supply output terminal of the near-field wireless communication transceiver module and the aircraft controller.

[0018] Furthermore, the method by which the MCU module realizes wireless parameter binding of the aircraft through data transmission to be bound between the MCU module and the aircraft controller includes:

[0019] The system determines whether the MCU module stores data to be bound. If data to be bound exists, it uploads the data to the aircraft controller. After receiving the data and verifying it, the aircraft controller sends a receiving completion command. If the MCU module does not receive the receiving completion command from the aircraft controller, it uploads the data to be bound again at a predetermined time interval.

[0020] After the aircraft controller sends a completion command, it sends the data to be bound back to the MCU module. The MCU module verifies the data. If the verification passes, it sends a verification pass command to the aircraft controller; otherwise, it sends a verification failure command. After receiving the verification pass command, the aircraft controller sends an erase command and a binding success command to the MCU module in sequence. After receiving the erase command and the binding success command, the MCU module executes the erase operation and illuminates the binding success indicator light in sequence.

[0021] Furthermore, after receiving the erase command and the binding success command, the MCU module stops the current workflow and executes the command.

[0022] Furthermore, the verification methods include:

[0023] The data frame containing the data to be bound is set to include a checksum byte at the end. After receiving the data frame, the aircraft controller verifies the correctness of the valid data by checking the checksum byte.

[0024] The function of sending back the data to be bound to the aircraft controller has been added. The MCU module verifies whether the data to be bound received by the aircraft controller is correct by comparing the sent data with the returned data.

[0025] A method for setting wireless parameters of an aircraft, implemented using the aforementioned wireless parameter setting system, includes:

[0026] The power management module receives the voltage input from the aircraft controller or the near-field wireless communication transceiver module, converts the voltage into DC / DC power to supply power to the RS-422 transceiver module, the MCU module, and the near-field wireless communication transceiver module; the near-field wireless communication transceiver module performs data transmission between the MCU module and the ground terminal, and simultaneously receives the voltage transmitted from the ground terminal and outputs the voltage transmitted from the ground terminal to the power management module.

[0027] The MCU module receives the data to be bound from the near-field wireless communication transceiver module, stores the data, and transmits the data to be bound between the RS-422 transceiver module and the aircraft controller when powered by the voltage input to the aircraft controller, thereby realizing the wireless binding of aircraft parameters.

[0028] The present invention employs the above-described system and method to quickly achieve the purpose of loading mission parameters through wireless communication technology without electrical interconnection with the carrier aircraft.

[0029] Compared with the prior art, the present invention has at least one of the following advantages:

[0030] (1) This invention creatively proposes an aircraft wireless parameter binding system, which adopts wireless power transmission technology and power conversion chip, and is compatible with both power-on and power-off binding methods. It can receive and store binding parameters sent by ground terminal when the aircraft is not powered.

[0031] (2) This invention achieves the function of verifying communication data with ground terminals and aircraft controllers by designing specific communication protocols and communication processes;

[0032] (3) The present invention can enter normal mode or low power consumption mode according to different power sources, which can effectively improve resource utilization and improve binding efficiency.

[0038] The features and advantages of the present invention will become clearer and more apparent from the following detailed description.

[0039] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments. Although various aspects of embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated otherwise.

[0040] This invention is a system for modifying critical parameters of an aircraft using wireless communication technology. Based on the need to modify critical parameters of the aircraft's internal controller, this invention enables the modification of critical aircraft parameters without disassembling the outer shell or having any electrical connection with the carrier aircraft. It features safety, accuracy, convenience, and rapid response.

[0041] The system of this invention includes:

[0042] (1) A dual-input anti-reverse-feedback power management circuit (power management module)

[0043] This module includes a DC / DC voltage regulator circuit and a reverse current protection circuit. The power management circuit inputs include two channels: the aircraft controller power supply voltage and the near-field wireless transmission voltage. The aircraft controller input voltage and the near-field wireless transmission voltage are both relatively high and cannot be directly used by the IC of the near-field wireless communication transceiver module in the aircraft's wireless binding system. Therefore, they need to be converted to low voltage by different DC / DC circuits to supply the IC. When both voltages are present, to prevent reverse current from flowing back due to a voltage difference, which could damage the aircraft controller, a reverse current protection measure is added to the power management circuit. This involves connecting reverse current protection diodes in series at the output terminals of both voltages to prevent reverse current flow.

[0044] (2) An RS-422 conversion circuit (RS-422 transceiver module)

[0045] This module can convert the serial communication signal output by the MCU into the RS-422 standard and connect it to the conversion circuit on the aircraft controller through an external interface, thereby realizing the reception and transmission of data with the aircraft controller.

[0046] (3) A wireless communication and energy harvesting circuit (near-field wireless communication transceiver module)

[0047] This circuit module enables wireless communication data transmission and reception, as well as energy harvesting. Wireless communication facilitates data exchange with ground terminal equipment; energy harvesting obtains energy from the ground terminal to power the aircraft's wireless parameter setting system, thus allowing data transmission, reception, and storage with the ground terminal even when the aircraft controller is not powered. Near-field wireless communication technology is used for both wireless and energy harvesting to minimize transmission distance, thereby reducing electromagnetic interference to internal aircraft components and energy loss during transmission.

[0048] (4) An input voltage detection circuit and an MCU dual-mode switching module (MCU module)

[0049] The input voltage is sampled to determine the power source. If the power source is wireless, the MCU will enter a low-power mode to reduce energy consumption while meeting communication speed and storage capacity requirements, thus allowing for more tolerant binding gaps and sway errors. If the power source is the aircraft controller and the power supply is sufficient, the MCU will enter normal mode.

[0050] Communication process for data verification:

[0051] First, a checksum byte is set at the end of the data frame. After receiving the data frame, the aircraft controller verifies the correctness of the valid data by using the checksum byte. Second, a data binding feedback function is added to the aircraft controller. The aircraft wireless parameter binding system verifies whether the binding data received by the aircraft controller is correct by comparing the feedback data with the transmitted data.

[0052] The data correctness is verified from both the aircraft's wireless parameter setting system at the transmitting end and the aircraft controller at the receiving end, thereby increasing data reliability.

[0053] Example:

[0054] like Figure 4 This invention discloses an aircraft wireless parameter binding system. It employs near-field wireless communication technology to achieve wireless communication between the system and a ground terminal. It uses a single RS-422 interface to communicate with the aircraft controller, enabling parameter binding for the controller. Utilizing wireless power transfer technology and a power conversion chip, it is compatible with both powered and unpowered binding methods, allowing it to receive and store binding parameters sent by the ground terminal even when the aircraft is not powered. Through the design of a specific communication protocol and process, it achieves data verification functionality with the ground terminal and the aircraft controller.

[0055] The method for realizing wireless communication between the aircraft wireless parameter binding system and the ground terminal using near-field wireless communication technology includes: using near-field wireless communication technology, the aircraft wireless parameter binding system obtains the data to be bound from the ground terminal; the MCU on the aircraft wireless parameter binding system verifies and parses the received data according to the communication protocol, and stores the parsed data into the on-chip Flash.

[0056] The method for implementing parameter binding of the aircraft controller by communicating with the aircraft controller through a single RS-422 interface includes: after the aircraft controller is powered on, the wireless parameter binding system binds the data transmitted by the ground terminal to the aircraft controller through the RS-422 interface; the wireless parameter binding system and the aircraft controller perform data verification communication; after confirming that the data received by the aircraft controller is correct, the wireless parameter binding system erases the on-chip Flash data to facilitate the next reception and storage of data sent by the ground terminal.

[0057] Methods that are compatible with both powered and unpowered binding methods include: the wireless parameter binding system can obtain power from both the ground terminal and the aircraft controller, thereby ensuring data reception and storage when the aircraft controller is not powered on, and reading and binding the data after the aircraft controller is powered on.

[0058] The communication data verification function includes: the communication data contains a checksum data frame, and the aircraft controller sends back the data for verification after receiving the data. The parameter binding work is completed after both the aircraft wireless parameter binding system and the aircraft controller confirm that there are no errors.

[0059] Figure 1 The diagram shows the module configuration of an example of the present invention. The device mainly includes an MCU module, a near-field wireless communication transceiver module, a power management module, and an RS-422 transceiver module, and communicates with the aircraft controller through an external interface.

[0060] The ground terminal transmits binding data and energy to the near-field wireless communication transceiver module via near-field wireless communication. The MCU module receives the data and stores it in Flash memory for subsequent parameter binding. After the aircraft controller is powered on, the MCU module first checks if binding data exists in the Flash memory. If it does, it uploads the data to the aircraft controller. Upon receiving and verifying the data, the aircraft controller issues a reception completion command. If the MCU module does not receive the reception completion command from the aircraft controller, it re-uploads the binding data at 200ms intervals. After the aircraft controller issues the reception completion command, it sends the binding data back to the MCU module. The MCU module verifies the data. If the verification passes, it sends a verification success command to the aircraft controller; otherwise, it sends a verification failure command. Upon receiving the verification success command, the aircraft controller sequentially sends an erase Flash command and a binding success command to the MCU module. Upon receiving these commands, the MCU module sequentially erases the Flash memory and illuminates the binding success indicator light. In the above workflow, when the MCU module receives an erase Flash command or a binding completion command, it stops the current workflow and executes the command. Figure 2This is a flowchart illustrating the communication process between the binding system and the aircraft controller.

[0061] like Figure 3 After power-on, the MCU on the aircraft's wireless parameter binding system determines whether the aircraft controller is powered on by sampling the voltage at the output terminals of the wireless power supply and the aircraft controller power supply, respectively. If the aircraft controller is not powered on, to save energy consumption, the current workflow is stopped, the system executes instructions to enter low-power mode, and performs data reception and storage operations from the ground terminal. If the aircraft controller is powered on, the MCU module enters normal mode and checks whether data is stored in the Flash memory and performs data binding operations.
