Synchronizing clock signal generator is used to emit synchronizing clock signals, and transmitting the signal by control signal transmission circuit
To dynamic signalling analysis instrument and camera control desk so that synchronizing clock signals T-time tractor caterpillar and soil box soil
The video that pressure data, soil deformation image and high-speed camera between earth take is according to corresponding time relationship simultaneous transmission
It stores into host computer, and is shown on host computer.
