The present invention discloses a single board, electric equipment and a single board power supply control method. The single board includes a function module, at least two switch modules and a communication module; the function module is used for implementing the services of the single board; each of the at least two switch modules includes a first end and a second end; the first ends are used for connecting the function module, and the second ends are used for connecting different main power source boards; and the communication module is used for connecting the control ends of the switch modules, receiving the control commands of an external monitoring control board, and controlling the states of each switch module according to the control commands, so that a main power source board connected with a switch module in an on state supplies power to the single board. According to the single board, electric equipment and single board power supply control method of the invention adopted, when another single board is inserted, the monitoring control board selects an optimized main power source board from the plurality of main power source boards according to a priority sequence to supply power to the single board, and therefore, global unified scheduling and power distribution can be realized.
Description
technical field [0001] The invention relates to the technical field of DC power supply, in particular to a single board, electrical equipment and a single board power supply control method. Background technique [0002] As we all know, traditional communication equipment usually provides power in two ways, centralized power supply and fixed partition power supply. The centralized power supply mode is to supply power to the entire communication equipment through a main power board and a backup power board, but this power supply mode is only applicable to scenarios with low power consumption of the communication equipment. If the power consumption of the communication equipment is large, the power board The design is complicated, the technical realization is difficult, the volume is large, and the cost is high. As the power consumption of communication equipment continues to increase, there is a partition power supply method, which divides communication equipment into multipl...
