Function:
- The function for the main engine: Any set can be the main engine. Once the current main engine occur the breakdown ,can exchange another set to be the main engine. But the signal line of the Pressure Sensor must be moved to the new main engine accordingly .
- The function of Adding Pump and reducing Pump: Finish the several Pump according to the Adding and Reducing.
- With the resting state and Awaken Function 
- With the function of exchange Pump on timely 
- With the function of Antifreeze and waterproof.
- With the function for exchanging the Pump automatically when occur the breakdown. Once any set of the machine appears the mistake, the system will overleap this part automatically .To be ensure the stability of the system . 
- Alarm for watering :With the alarming function for HO,LO ,LP
