Abstract
The electricity-saving device controlling switching-on and switching-off of power supply of computer monitor is comprised of keyboard signal amplification circuit, mouse signal amplification circuit, timer and monitor power supply control circuit which are connected together. If in the time set by said timer, when there is no operation signal continuously using keyboard or mouse, the power supply of said monitor is switched off, and if a key-pressing operation or movement of the mouse is produced, the monitor can be started again, so that it can save electricity and prolong the service life of the monitor.
Description
The present invention relates to a kind of computer output device, relate to a kind of energy-saving device of controlling computer monitor power supply break-make or rather.
Even to this day, PC and workstation have been widely used in the information processing aspect, and hundreds of millions of computers play an important role at aspects such as development science and technology, economy, culture, yet also reflect another problem, and the promptly huge energy is paid and expended.
Before new substitute energy does not come out as yet, rationally and effectively energy-conservation is instant work, operating characteristic according to existing computer, analyze its idle time often greater than time of its work, because the processing speed of central processing unit CPU is far faster than the input speed of external unit, because the greatly different gap on the speed has caused the CPU (central processing unit) most of the time to be in idle state, though progress along with input-output device, this state can make moderate progress, but the people is cause idle still unavoidable, but forgotten to turn off monitor as pausing operation midway, perhaps handle other and import irrelevant paper work etc., therefore accumulate over a long period and caused a large amount of wastes of electric power.
The objective of the invention is to design the battery saving arrangement of the automatic controlling computer monitor power supply of a kind of energy, the computer of widespread use also can be contributed for energy-conservation, but cost fund is again upgraded power-supply device or motherboard, but also to respect the long-term work habit that forms of user, obtain maximum benefit with the cost of minimum.
Battery saving arrangement of the present invention can cut off monitor power supply automatically behind the idle certain hour of computer, in case the power supply that idle state can recover monitor again when finishing is immediately set up this device and can be prolonged the monitor life-span and save the energy.
The battery saving arrangement of automatic controlling computer monitor power supply of the present invention, utilize standard input device keyboard and the Genius mouse different output states when idle, cooperate timer to control the state of output block, in the time that sets, if throw the signal that continues to use input equipment arranged, output block then cuts off monitor power supply, up to having used keyboard or Genius mouse, occurs using signal then to connect monitor power supply by output block.
The present invention should reach the purpose of economize on electricity really under the condition that does not influence normal use.
The battery saving arrangement of automatic controlling computer monitor power supply of the present invention is connected and composed by computer Input Monitor Connector circuit, timing circuit, monitor power supply control circuit, it is characterized in that:
