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 creative work are within the scope of protection of the present invention.

[0047] The present invention provides Figure 1-16 A cockpit control panel for a GPS Beidou switching switch applied to ADS-B OUT is shown, comprising: a control panel body 5 and a rear adapter plate 7, wherein the rear adapter plate 7 is arranged on the back of the control panel body 5, and fixing screws 1 are installed on the opposite sides of the control panel body 5 and the rear adapter plate 7, and extension screws 2 are installed at the corners between the control panel body 5 and the rear adapter plate 7, and the fixing screws 1 are threadedly inserted into the ends of the extension screws 2, and quick-release screws 3 are installed at the corners of the control panel body 5 and the two ends of the rear adapter plate 7, and the quick-release screws 3 are used to fix the positions of the control panel body 5 and the rear adapter plate 7, and the extension screws 2, the control panel body 5 and the rear adapter plate 7 constitute the main structure of the control panel, and the fixing screws 1 are respectively connected to the extension screws 2 at the opposite ends of the control panel body 5 and the rear adapter plate 7, so that the control panel body forms a stable body, which meets the airworthiness requirements of the aircraft cockpit. The control panel body 5 is installed on the front side of the control panel body, and the control panel body 5 and the rear adapter plate 7 are both rectangular plate structures. Four screw holes are opened at the corners of the control panel body 5 for the quick-release screws 3 to be inserted into the screw holes, and the quick-release screws 3 are used to fix the control panel body 5 and the cockpit;

[0048] It also includes: a back socket 6, a switching switch 9 and an ARINC analysis module. The back socket 6 is installed on the rear adapter plate 7. Short screws 4 are installed at the corners of the back socket 6. The short screws 4 are used to connect and fix the back socket 6 to the rear adapter plate 7. The short screws 4 are fixed to the cockpit fixing plate to stabilize the main structure of the control panel. The switching switch 9 is installed on the control panel body 5. The switching switch 9 is used to switch between Beidou and GPS position sources. The ARINC analysis module is installed between the control panel body 5 and the rear adapter plate 7.

[0049] Specifically, the ARINC analysis module includes: a Beidou status indicator light 8 and an ARINC analysis component 10. A square hole compatible with the Beidou status indicator light 8 and the switching switch 9 is provided on the control panel body 5. The Beidou status indicator light 8 is installed on the control panel body 5. The Beidou status indicator light 8 and the switching switch 9 are respectively inserted and connected to the inner cavity of the square hole. The ARINC analysis component 10 is arranged on the rear adapter plate 7. The ARINC analysis component 10 is electrically connected to the back socket 6. The Beidou status indicator light 8 is electrically connected to the ARINC analysis component 10. The back socket 6 is responsible for interconnecting with other aircraft systems to provide status data for the ARINC analysis module. The ARINC analysis component 10 can parse ARINC429 signals or capture fault discrete signals to provide signal information for the Beidou status indicator light 8. The outer wall of the ARINC analysis component 10 is connected with a fixing bracket 11. The fixing bracket 11 is fixed to the other end of the rear adapter plate 7 by a quick-release screw 3. The fixing bracket 11 facilitates the ARINC analysis component 10 to be stabilized on the side of the rear adapter plate 7 facing the control panel body 5.

[0050] Further, the switching switch 9 is for switching between Beidou and GPS. The switching switch 9 includes: a compact body 12 and a first connector 13. The first connector 13 is inserted and connected to one end of the compact body 12. The compact body 12 is fixed to one end of the control panel body 5 by snapping. The switching switch 9 is designed as an internal momentary action switch, which directly provides manual input to the microcontroller, that is, pressing the switch cover. The momentary switch can be programmed as a backup action switch. The microcontroller signal processing diagram is shown in FIG. Fig.15As shown, in order to maximize the use of the 32-pin solderless connector, 5 external pins can be used as discrete inputs or discrete outputs specified at run time. Depending on the specific application, the switch can have up to 16 discrete inputs (including 8 analog functions) and up to 9 discrete outputs. The solderless first connector 13 plug accepts 22 to 28 gauge crimped wire connections. During installation, first ensure that the pins or contacts can be accurately matched. Pay special attention to any marks or positioning structures at the A and B positions on the compact body 12 and the first connector 13 to ensure that the insertion direction is correct. The compact body 12 and the first connector 13 are plug-in designs. The design can use a snap-on or locking mechanism to ensure that the compact body 12 and the first connector 13 can be smoothly and firmly engaged together. A relay is connected to the outside of the control panel body 5. The switch switching circuit is responsible for the relay control outside the control panel body. It is composed of the back socket 6 and the switch 9. In normal conditions, the ADS-B OUT system uses the GPS position source. Press the switch 9, ADS-B The OUT system switches to the Beidou position source, and the switching switch 9 circuit is connected to the back socket 6, which is responsible for connecting to the relay of the switching switch and providing a level signal to the relay. After pressing the Beidou / GPS switching switch 9, the internal momentary action switch state changes rapidly, the circuit closes, the control circuit is activated, and the relay is driven to start working. In this process, the electromagnet of the relay is activated, thereby switching its internal contacts, effectively switching the input signal of the ATC transponder to the Beidou signal. The Beidou signal is transmitted to the ATC transponder through the output end of the relay, realizing rapid switching of the signal source. When the switch is pressed again, the circuit is disconnected, the electromagnet of the relay loses power, and the contacts are reset. After the relay contacts are reset, the input signal of the ATC transponder will be switched back to the GPS signal, thereby completing the entire switching process and ensuring that the signal source can be flexibly converted as needed. The switch switching indication diagram is shown as follows Fig.16 shown.

[0051] The Beidou status indicator light 8 includes: a high-capacity body 14 and a second connector 15. The high-capacity body 14 is mounted on the second connector 15. The high-capacity body 14 is fixed to the other end of the control panel body 5. The high-capacity body 14 has four available positions (H, J, K, L) for configuring electronic components of different sizes and functions. The electromechanical switch rod can be used to replace the A series component. An Open spacer will be configured in the unoccupied position. The Beidou status indicator light 8 receives discrete signals from the ARINC429 analysis component. When the Beidou signal is in a normal state, the Beidou status indicator light 8 usually lights up or displays a specific color, such as green, to indicate normal operation. The circuit monitors the strength and integrity of the signal in real time through multiple methods such as analog signal detection, bit error rate detection, signal strength comparison, and delay analysis, thereby ensuring the reliability of the signal. If the Beidou signal fails, the circuit will quickly sound an alarm, and the color of the Beidou status indicator light 8 will change, such as turning red or starting to flash. At the same time, the system may send a fault message to notify the pilot in time, thereby achieving effective fault warning and response. During the installation process, the high-capacity body 14 is placed on the second connector 15 to ensure that the H, J, K, and L slots on the second connector 15 are accurately matched with the plug of the high-capacity body 14. The high-capacity body 14 and the second connector 15 adopt a plug-in design, and a snap or rotary lock can be used in the design to ensure that the high-capacity body 14 and the second connector 15 can be smoothly and firmly engaged together.

[0052] Furthermore, the ARINC parsing component 10 includes: an ARINC429 signal converter and a matching connector, the matching connector is inserted into one end of the inner cavity of the ARINC429 signal converter, and the ARINC429 signal converter can capture any bit of the 32-bit ARINC 429 data word of the specified tag, and any bit of the data word is as follows Fig.11As shown, the ARINC429 signal converter converts it into the required discrete output through a pre-programmed configuration. The ARINC429 signal converter can also receive data from other devices through the pins of the matching connector. According to the needs of data conversion and output control, the ARINC429 signal converter has three configuration types, namely single-bit converter, multi-bit converter and multi-bit decoding converter. The ARINC429 signal converter avoids many disadvantages of ARINC429 parsing equipment in terms of structural size, cost and complexity, and is practical. The ARINC429 signal converter works at a voltage of 28V and a current limit of up to 8mA, and the GND end needs to be continuously grounded. The ARINC429 signal converter can capture any bit of the ARINC429 data word of the specified label (bits 0-7 of ARINC429) to drive a single bit or multiple bits of discrete output. The ARINC429 signal converter also supports enabling and disabling the SDI bit (bits 9 / 10 of ARINC429) of the ARINC429 data word to achieve effective data source identification, and provides options for enabling parity and selecting high-speed or low-speed transmission. The ARINC429 signal converter can also receive data from other devices through the connector pins, which may include sensors, signal converters, etc. The ARINC429 signal converter processes the received data according to the built-in algorithm, converts the data format, and transmits information to other systems or devices through the matching connector. The ARINC429 signal converter can be connected to various types of switches, which can be used to set different operating modes or states, such as switching different data sources or configuration parameters. The ARINC429 signal converter also has an output interface for driving indicators, which can be LEDs, LCDs or other display devices to reflect the system status or important data in real time. For example, when a flight parameter exceeds the safe range, the indicator will light up a warning signal.

[0053] In particular, the three ARINC429 signal converters, namely the single-bit converter, multi-bit converter and multi-bit decoded converter, are configured with different output control activation options, namely discrete output, decoded output and fault output. In the inactive state, all outputs are open drain (high impedance). The output load capacity of the single-bit converter is 1.0A (resistance), while the output load capacity of the multi-bit converter and multi-bit decoded converter is 0.5A (resistance). The circuit output diagram of the single-bit converter is shown in Fig.13 shown.

[0054] Among them, the single-bit ARINC429 signal converter is an eight-pin device that provides a discrete output (OUT) and a fault output, wherein the discrete output content is determined by the captured specified tag and any bit data contained in the tag through pre-programmed settings, and the fault output is activated when the fault detection circuit recognizes a fault. In the ARINC parsing component 10, the ARINC429 signal converter is configured as a single-bit converter. The single-bit converter first captures data from the ARINC429 bus through the receiving pin (RX pin) of the ARINC429 data line, and captures the ARINC429 data 24-28 bits of tag 273. The captured signal is analyzed by the decoding module to extract the valid data bits and obtain the working status of the Beidou position source. After decoding, the single-bit converter converts each data bit into a format suitable for subsequent processing, usually converting the data bit into a digital signal (0 or 1), which then corresponds to a specific discrete signal, which can be a high level (representing 1) or a low level (representing 0), through the digital signal output pin (TX pin or corresponding control signal pin), and its pre-programmed configuration is as follows:

[0055]

[0056] The discrete signal is used to drive the BeiDou status indicator 8 to indicate the working status of the BeiDou equipment to the pilot, provide real-time status feedback, and avoid aviation safety issues caused by switching the ADS-B OUT position source when the position source is abnormal. Figure 8 In the figure, the ARINC analysis component 10 includes four available positions (H, J, K, L) for installing electronic components of different sizes and functions, and the ARINC429 signal converter can be configured with a matching connector for human-machine interface equipment. The ARINC analysis component 10 can be installed in a guide rail, bracket or harness style. The ARINC429 signal converter is usually installed in front of the matching connector. The 5 external pins of the matching connector can be used as discrete inputs or discrete outputs specified at runtime. Depending on the specific application, there can be up to 16 discrete inputs (including 8 analog functions) and up to 9 discrete outputs. The 32-pin solderless connector plug accepts 22 to 28 gauge crimping wire connections. Its signal diagram is as follows Fig.12 shown.

[0057] The matching connector and ARINC429 signal converter are installed in four available positions (H, J, K, L). Each position (H, J, K, L) is equipped with a specially designed slot or interface, with a specific shape and size reserved to ensure that the converter and connector can be accurately docked during installation. The single-bit converter and matching connector usually adopt a plug-in design, which ensures the simplicity and reliability of the physical connection. In order to enhance the stability of the connection, the design usually includes a locking mechanism, such as a snap or a locking pin, to prevent the components from shifting during use. When the connector and the single-bit converter are connected, the pins in the connector will be in close contact with the contact points of the converter. The pins and contact points usually use metal springs or other conductive materials to ensure that the electrical signals can be transmitted smoothly, minimize the occurrence of signal interference, and ensure the accuracy of data transmission. As shown in the attached Fig. 9 As shown, there are two available positions (A, B) in the compact structure inside the switch 9 for configuring electronic components of different sizes and functions.

[0058] Working principle of the present invention:

[0059] The ARINC parsing component 10 is fixed on the rear adapter plate 7 by a fixing bracket 11, and the ARINC parsing component 10 is located between the control panel body 5 and the rear adapter plate 7. Under normal conditions, the position source of the ADS-B OUT system is the GPS position source. Pressing the switch 9 provides a level signal to the relay outside the control panel body 5. The closed state of the relay can control the switching switch of the position source to achieve the purpose of switching to the Beidou position source. When the pilot selects an ATC transponder with a Beidou data source installed on the ATC control panel body 5 and the Beidou navigation mode is selected on the Beidou cockpit control panel body 5, the aircraft ADS-B OUT system operates in the Beidou mode and sends the position source data provided by the Beidou navigation receiver. The ARINC parsing component 10 obtains the aircraft status data, parses the ARINC429 signal or captures the fault discrete signal, and is connected to the Beidou status indicator light 8 to provide it with a Beidou status signal. The ADS-B OUT Beidou and GPS position source switching function and the function of displaying the current status of the Beidou receiver facilitate pilots' management and operation of the ADS-B OUT equipment and meet the airworthiness requirements of civil aircraft. The equipment can not only enhance the stability and reliability of the system, but also meet the ever-changing technical requirements and aviation safety standards.
