The power supply device 500 includes: the timing power supply 510 and the distribution box 520, and the timing power supply 510 and the distribution box 520 are connected with the master control module 110 and are turned on or turned off according to an instruction of the master control module 110. Because the start-stop sequence of some devices in the application is specified, if the start-stop is not performed according to the sequence, the damage of related devices can be caused, so that a time sequence power supply is adopted for the devices, the master control module 110 controls the devices through a network, when the devices are started, the power is supplied to the devices one by one from the front-stage devices to the rear-stage devices, and when the devices are closed, the power is stopped sequentially from the rear-stage devices to the front-stage devices. In one embodiment, the power supply apparatus 500 includes four timing power supplies 510.
The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments. The above description is only a preferred embodiment of the present application, and is only for the purpose of illustrating the technical solutions of the present application, and not for the purpose of limiting the present application. Any modification, equivalent replacement, improvement or the like, which would be obvious to one of ordinary skill in the art and would be within the spirit and principle of the present application, should be included within the scope of the present application.
