(18) voltage is provided to system control cpu, and wherein system control cpu has the function of three aspects: first is that wireless regulating command is received,
And the information such as crank position；Second is that sending the switching control instruction of electrically-controlled valve；Third is that each sand reservoir box cabinet internal volume calculates storage；
System control cpu obtains the adjustment information that acquisition instructs module to give by wireless receiving module first, is passed by three shaft positions
Sensor (17) determines specific location where the crank of movement, and electric control valve is switched in a certain range of running track and realizes iron
The migration of sand；
Four, balance check and strategy amendment after adjusting:
After completing balance automatic adjustment, balanced ratio after adjusting is calculated at interval of acquisition in 4 hours, continuously measures 6 points, and acquisition is adjusted
Circuit parameter after whole, and whether calculated equilibrium rate, if meeting, stops sending regulating command between the 90%-110% of optimization,
Into cycle operation mode, acquisition judges that balanced ratio section changes weekly；
If not meeting, is judged whether there is according to volume calculations and adjusts space, next step adjusting is carried out if having adjustment space,
Send regulatory demand if without space is adjusted and instruct to acquisition and instruct module, carry out data feedback, install additional or reduce sand reservoir box into
The lower step section of row.
