Abstract
Description
Technical Field
[0001] This utility model relates to the field of MCP control box technology, specifically an MCP control box based on CAN bus. Background Technology
[0002] The MCP (Mode Control Board) of the Boeing 737 flight simulator is one of the core control components of the flight simulator, used to set and adjust key parameters such as autopilot, navigation, altitude, and speed during simulated flight. Part of the control box includes a cover and a body. The cover is placed on the body, forming a cavity between the cover and the body, where the control module is installed. A through-hole is provided on the body, through which a cable adapter module is detachably installed. The cable adapter module is used to connect to the power and signal sources. The side of the control module facing the through-hole has electrical contacts for programming, corresponding to the through-hole. After the cable adapter module is removed, the contact pins of the programmer can connect to the electrical contacts through the through-hole. This invention achieves the effect of reducing the number of openings in the body and reducing sealing difficulty. However, the internal circuit structure of this device is relatively simple, which may lead to errors in data signal acquisition and output during simulated flight. Furthermore, the device's communication and expandability have room for improvement. Therefore, we propose an MCP control box based on a CAN bus. Utility Model Content

There are knob caps 10, all located on the front side of panel 9. Electrical connector 2 is a CAN bus interface. When using a CAN bus-based MCP control box, the device is connected to an external flight simulator host via electrical connector 2. An external power supply provides power to the acquisition board 3. The acquisition board 3, as the main control module, communicates efficiently with the external flight simulator host via the CAN bus interface. The light guide circuit board 8 has an AD conversion circuit capable of simultaneously processing digital switch signals and analog knob signals. The AD conversion circuit is connected in series to the circuit that bidirectionally connects the acquisition board 3 and the knob mechanism 4.

[0014] The working principle of the CAN bus-based MCP control box provided by this utility model is as follows: When using the CAN bus-based MCP control box, the device is connected to the external flight simulator host through the electrical connector 2. The external power supply provides power support for the operation of the acquisition board 3. The acquisition board 3, as the main control module, communicates efficiently with the external flight simulator host through the CAN bus interface. The light guide circuit board 8 is equipped with an AD conversion circuit, which can simultaneously process digital switch signals and analog knob signals. The AD conversion circuit is connected in series to the circuit in which the acquisition board 3 and the knob mechanism 4 are bidirectionally electrically connected. The acquisition board 3 starts the knob mechanism 4 and the LCD 7. The simulator operator rotates the knob cap 10 to drive the knob inside the knob mechanism 4 to rotate. The knob mechanism 4, as an input module, triggers an internal electronic response through rotation, thereby determining the direction of the current and realizing the adjustment of the output flight simulation data. The output flight simulation data is presented as an electrical signal. The signal is transmitted to the acquisition board 3. This electrical signal passes through the AD conversion circuit on the light guide circuit board 8. The AD conversion circuit on the light guide circuit board 8 converts the analog knob signal of the knob mechanism 4 into a digital switch signal and transmits it to the acquisition board 3 as an electrical signal. (The light guide circuit board 8 is equipped with an operational amplifier to process the analog data signals input to or output to the acquisition board 3, thereby achieving high-precision analog signal acquisition and output and ensuring accurate control of flight parameters.) After receiving the digital command, the acquisition board 3 transmits this signal to the LCD 7 as an electrical signal for data display, which facilitates intuitive observation of flight simulation data by the simulator personnel. At the same time, the acquisition board 3 activates the corresponding signal light 5. The signal light 5 serves as an output module to provide feedback status indication to the simulator personnel. When using the CAN bus-based MCP control box, multiple devices can be connected and dynamically configured, making it suitable for complex flight simulation environments.
