In order to more accurately study the parameters in the Galatea device, establish the mathematical model of the probe and timing control system in the Galatea device, and select the PCI-1780U switch board as the hardware core to build the timing control system. Use LabVIEW to program the host computer for the timing control system. After constructing the software and hardware structure of the whole timing control system, the difference between the timing pulse and the theoretical value of each part of the device is verified by experiments, and the corresponding relationship between the timing control pulses of each part in the device is obtained.
