Power supply.
7. a kind of method that power-supplying circuit based in claim 1 realizes smart machine quick turn-on, which is characterized in that
Including step：
When receiving power-on instruction, the signal output part of MCU is controlled to export control signal, so that the direct current of power-supplying circuit turns
The second memory block for changing the mold block and smart machine is connection status；
The power module output services voltage of power-supplying circuit is controlled to the DC conversion modules, and passes through direct current modulus of conversion
Block is the first memory block of smart machine and the power supply of the second memory block；
The software code in first memory block is loaded, initializes the hardware device of smart machine, enters smart machine and opens
Machine state；
Wherein, first memory block and second memory block include DDR chips.
8. the method for smart machine quick turn-on is realized as claimed in claim 7, which is characterized in that further include step：
When receiving standby command, the signal output part of MCU is controlled to export control signal, so that the direct current of power-supplying circuit turns
Mold changing block is disconnected with the second memory block；
The power module of power-supplying circuit is controlled to export standby voltage to the DC conversion modules, and passes through direct current modulus of conversion
Block is powered for first memory block；
The operating rate of first memory block is reduced, smart machine is made to enter holding state.
9. as claimed in claim 8 realize smart machine quick turn-on method, which is characterized in that it is described receive it is standby
During instruction, control MCU signal output part export control signal the step of before, further include step：
The software code and standby data for judging smart machine start whether there is in first memory block；If it is not, by intelligence
Software code and standby data in the flash chip of energy equipment are copied in first memory block.
10. the method for smart machine quick turn-on is realized as claimed in claim 8, which is characterized in that received out described
Machine instruct when, control MCU signal output part export control signal the step of before, further include step：
Improve the operating rate of the first memory block of the software code for being stored with smart machine start and standby data.
