Abstract
The invention discloses a multi-power-source allocation device and a control method. The device comprises a power source input plug, a master control power source socket, at least one controlled power source socket and a control circuit, wherein the power source input plug is connected to a main supply circuit. The method is as follows: based on a concept of two sections type thresholds namely a starting up power threshold and a shutting down power threshold, the starting up power threshold is necessarily set to be higher than the shutting down power threshold; when the electricity power of the master control equipment is higher than the shutting down power threshold, the controlled power source socket is started so as to provide an accessory equipment power source; and when the electricity power of the master control equipment is lower than the starting up power threshold because of influence of variation of partial power of the master control equipment, the controlled power source socket is not shut down temporarily, and the controlled power source socket is shut down only when the electricity power of the master control equipment is lower than the hutting down power threshold.
Description
Technical field
The present invention relates to a kind of have many electrical power distribution apparatus of master-slave architecture and the control method of master-slave architecture, refer in particular to a kind of active and according to the electricity consumption of master control supply socket, change start, standby or the off-mode of identification main control device, to judge the condition of power supply of setting controlled source socket.
Background technology
Increasing electric equipment has subordinate relation, for example using computer as main control device, and be attached to tabulating machine, external hard drive, monitor screen of computer requirements etc., when computer booting is worked, these auxiliary devices are in harness demand, and after computer shutdown, these auxiliary devices do not need work yet.For example using television set again as main control device, only have when television set is opened, attached videocorder, loud speaker, DVD etc. just have necessity of start operation, once after television set shutdown, these auxiliary devices are also relative does not have in harness necessity.
For the main control device and the auxiliary device that are connected to general electrical power distribution apparatus, when main control device needs work or shutdown, the power supply of auxiliary device must be opened artificially in addition or close.Not only therefore caused the inconvenience of using, and because common people are after main control device shutdown, custom does not remove to close the power supply of auxiliary device again, the waste that indirectly yet causes the energy to use.
For this reason, there is the conceptual design of so-called principal and subordinate's socket, as United States Patent (USP) 4,731,549 (Current Sensor and Control Device), and for example United States Patent (USP) 5,563,455 (Method and Apparatus for Sequencing and Controlling Power Distribution) are all whether the main control device of detecting on main control socket has in electricity consumption, determine whether opening the mains switch on controlled soket.But present most main control device is to enter standby mode (Standby Mode) when not using, that is to say that main control device still can electric consumption under obsolete situation, just because there is standby mode that the power supply of controlled soket cannot be closed also just cannot to reach the object of the saving energy.
Further as US Patent No. 7,193,335B2 (Sensing Socket Assembly), this patent has been set an adjustable door (Threshold), and when the electricity consumption of main control device surpasses this door, the power supply of controlled soket can be opened.If the electricity consumption of main control device is during lower than this door, the power supply of controlled soket can be closed.Utilize the setting of this door, need only the standby mode electricity consumption of main control device lower than door, controlled soket can close to save electric energy as expected.Yet in practical operation, there is error because of the change of main control device start electricity consumption in the setting meeting of single door.For example, the electricity consumption meeting of television set along with the brightness of picture, the volume of broadcasting and occur changing, if the television set of usining just there will be electricity consumption to surpass door, the phenomenon that causes the auxiliary device being connected on controlled soket to start shooting and shut down lower than door once as main control device quickly quickly.A variety of owing to having as the electrical equipment of main control device in addition, neither identical with the setting of standby for start each other, be difficult to contain all application with a door.
Summary of the invention
The present invention's object is the deficiency existing in order to overcome prior art, and a kind of more practical many electrical power distribution apparatus and control method are provided.
Realizing many electrical power distribution apparatus of the present invention is: comprise a power input plug that is connected to mains supply circuit; A master control supply socket; At least one controlled source socket; A control circuit.
Realizing method of the present invention is: adopted two-part, the concept of start power door and shutdown power door.In setting, start power door is necessarily higher than shutdown power door.When main control device electric power is during higher than start power door, controlled source socket can be opened to provide auxiliary device power supply.When main control device electric power, because of the partial function influence of change of main control device, during lower than start power door, temporarily can not close controlled source socket, only have when main control device electricity consumption is during lower than shutdown power door, just can close controlled source socket.Same, when main control device makes electric power surpass shutdown power door because of the impact of idle function, temporarily can not open controlled source socket, only have when main control device electricity consumption is during higher than start power door, just can open controlled source socket.The present invention has utilized the pooling feature between start power door and shutdown power door, has solved the wild effect that auxiliary device opens and closes.
Simultaneously, method of the present invention has been taked oneself to adjust the mechanism of setting, according to the electricity consumption of main control device, change and automatically judge that main control device is now in open state or holding state, even as the charged state of mobile computer also can be judged correctly to determine whether will open or close controlled soket power supply.
The beneficial effect that the present invention has: reasonable distribution and utilize power supply more, realizes safe, efficient, energy-conservation effect.
