Embodiment
Please refer to Fig. 1, the power-supply management system 200 in present embodiment is executed in supply unit 100.Supply unit 100 comprises the PSU12 of controller 11 and multiple parallel connection.Multiple PSU12 for connect load (not illustrated) electric energy is provided.Power-supply management system 200 comprises multiple functional module being executed in controller 11.In the present embodiment, power-supply management system 200 comprises time statistical module 21 and control module 23.The method flow of the concrete function composition graphs 2 of modules is described.
In step S201, time statistical module 21 adds up the net cycle time of each PSU.
In step S202, control module 23 determines the quantity of the current PSU12 that should work every a preset time period according to the load value of the current load be connected with supply unit 100.When load value is large, the quantity of the PSU12 that should work is just many, and when load value hour, the quantity of the PSU12 that should work is just few.
In step S203, control module 23 determines the current PSU12 that should work and the current PSU12 that should have a rest according to the quantity of the net cycle time of each PSU12 and the current PSU12 that should work.Wherein, the net cycle time of each current PSU12 that should work is less than the net cycle time of each current PSU12 that should have a rest.In the present embodiment, control module 23 calculates the time difference of the average operation time of all PSU12 and the net cycle time of each PSU12 every preset time period, if the time difference that a PSU12 is corresponding is positive number, the working time representing this PSU12 is less than the average operation time of all PSU12, and namely the working time of this PSU12 is shorter.If the time difference that a PSU12 is corresponding is negative, the working time representing this PSU12 is greater than the average operation time of all PSU12, and namely the working time of this PSU12 is longer.Control module 23 sorts to all PSU12 according to the size of time difference, maximum the making number one of time difference in described sequence, namely the PSU12 that the working time is the shortest makes number one, according to the quantity of the current PSU12 that should work, control module 23 determines that the PSU12 be in described sequence is above the PSU12 that should work, namely control module 23 make the working time short PSU12 work, allow longevity of service PSU12 first rest a period of time.
In step S204, control module 23 makes the current PSU12 that should work enter duty, and the current PSU12 that should have a rest enters resting state.Control module 23 is when also a current PSU12 that should work fails normally to work wherein, such as temperature is too high causes cisco unity malfunction, start the PSU12 that in all current PSU12 that should have a rest, the working time is the shortest, to take over the current normal PSU12 worked that fails, can normally work with proof load.
In the present embodiment, control module 23 re-starts every the preset time period corresponding PSU12 worked and the PSU12 that should have a rest once to be determined, therefore, part PSU12 can proceed to resting state after a period of operation, and part PSU12 can proceed to duty after rest a period of time.Control module 23 determine with the PSU12 that the working time in all current PSU12 that should have a rest is the shortest take over current should enter the PSU12 of resting state from duty time, the PSU12 that working time is the shortest in all current PSU12 that should have a rest works after the schedule time, make the current PSU12 that should have a rest enter resting state from duty again, during to ensure the switching carrying out work and resting state between PSU12, load can normally work.
In present embodiment, arrange work and the rest of each PSU12 according to the net cycle time of each PSU12, to ensure the average operation time of the net cycle time of each PSU12 close to all PSU12, prevent some PSU12 from breaking down because the working time is long.
Time statistical module 21 in present embodiment and control module 23 can be also the firmwares being solidificated in controller 11, are the composition submodules of controller 11.
