Problems solved by technology

[0004] The traditional ultrasonic distance measurement has a single design, and the data transmission process is cumbersome, and it needs TXD, RXD to be connected with the computer to complete the data communication
In addition, due to the small space in the simulated cockpit and the simultaneous operation of multiple devices such as instruments, steering rods, and pedals, the transmission of ultrasonic waves in a small space will produce waveform superposition, which will affect the accuracy of measured values.
Therefore, the traditional method cannot fulfill the requirement of accurate ultrasonic distance measurement in the simulated cockpit
