[0037] Working principle:

[0038] In use, press the switch button 10 to align the laser emitted by the laser displacement sensor 4 with the object being measured, and connect the signal receiver converter to the PC host via USB to serial port 8. The PC host will automatically search and display the serial port device numbers connected online, and simultaneously initiate device disconnection and reconnection detection, meaning that the online serial port list will be updated every time a device is plugged in or unplugged from the serial port. The PC is in an unconnected state by default after startup, and the connection status light is red.

[0039] Open all online serial ports and wait for all connections to be ready. Then, set the sampling frequency on the main interface. The default sampling frequency is 100Hz, and the frequency range is 0.5 to 300Hz.

[0040] After the parameters are set, the PC host sends a control signal to the laser displacement sensor 4 of the signal acquisition transmitter to collect the distance data of the object being measured. The data is then sent to the data receiving module 7 of the signal receiving converter via the data sending module 5. The data receiving module 7 transmits the received data to the PC host via the USB to serial port 8. The PC host then saves the collected distance data to an Excel spreadsheet.
