The invention relates to an optical storage all-in-one machine technology, and discloses an optical storage all-in-one machine control method and an optical storage all-in-one machine, through arranging a grounding relay, opening and closing of the grounding relay are controlled according to a power grid side state, a grounding mode can be flexibly adjusted, faults of equipment and a power grid are effectively isolated, the risk of equipment damage is reduced, and the safety of a system is enhanced. Meanwhile, the four contactors are arranged as the power grid contactors, so that the N line can be disconnected by using the contactors as required, and the method is safer and more reliable compared with the method of directly using a thyristor to control the on-off of the N line; and the thyristor and the power grid contactor are simultaneously arranged on one side, connected to the power grid, of the grid-connected and off-grid circuit, so that the switching speed of the thyristor is relatively high when grid-connected switching to off-grid switching is needed, and the system can be rapidly switched to off-grid power supply through the thyristor when the power grid is suddenly powered off, thereby avoiding load power failure caused by relatively low switching speed of the contactor. The invention aims to improve the electrical safety and the system stability in the use process of the optical storage all-in-one machine.
