Abstract
A power supply control system of a monitor is used to automatically control the on-and-off state of a display unit, so as to save electric resource. The power supply control system of the monitor comprises a power supply unit, a main power switch and a display switch, which are connected in series in sequence; wherein the power supply unit provides a working voltage for a display unit, and the main power switch is used to control connection and disconnection of a circuit between the power supply unit and the display switch. In addition, the power supply control system of the monitor also comprises a human-body infrared induction unit, an input terminal thereof is connected with the main power control switch, and an output terminal thereof is connected with the display switch, so as to control the on-and-off state of the display switch; thus, when a user is absent with apologies during the process of using a computer, if the human-body infrared induction unit detects that no user is within a certain distance in front of the monitor, the human-body infrared induction unit sends off control signals to disconnect the display switch and consequently close the display unit.
Description
[technical field]
The power control system of the present invention relevant a kind of power control system, particularly a kind of display.
[background technology]
Computer monitor is as the standard configuration of computer apparatus, performance to computer function has critical role, the problem that but the power consumption of computer monitor and electromagnetic radiation but are industries has to pay close attention to, the LCD that has low power consumption and low radiation thus replaces traditional cathode-ray tube display just gradually, even so, but according under the existing display power control system framework, as shown in Figure 1, this display power control system 1 comprises the power-supply unit 10 of mutual serial connection, main power switch 11 and display unit 14, so under existing display power control system, the user only need activate main power switch 11 can make power-supply unit 10 provide display unit 14 required operating voltage, when the user is using in the computer process, when being gone for a season for some reason, this display unit 14 may be still in running order, thereby expending some answers savable electric weight and produces unnecessary electromagnetic radiation, certainly industry is also controlled when computer apparatus does not have operation within a certain period of time by software design, then enter standby, with the electric weight of reduction display consumes and the electromagnetic radiation of generation, this is to lose efficacy because of the user may forget to be provided with on the one hand, though be that the user is provided with on the other hand, but the display circuit of display still will consume certain electric weight and produce certain radiation this moment, thereby not only influence working environment, and can increase power consumption and influence serviceable life of display.
[summary of the invention]
The object of the invention is to provide a kind of display power control system, by in time cutting off the display unit power supply of display automatically, to overcome display power consumption and the excessive problem of electromagnetic radiation in the prior art.
For achieving the above object, display power control system of the present invention comprises the power-supply unit of serial connection successively, main power switch, display switch and display unit, wherein this power-supply unit provides display required operating voltage, and main power switch is in order to the connecting and disconnecting of the circuit between control power-supply unit and the display switch, and this display power control system also comprises a human body infrared induction unit, this human body infrared induction unit one input end is connected with the primary power gauge tap, and the output terminal of this human body infrared induction unit is connected with display switch, the closure of control display switch.
Compared with prior art, the present invention is by being connected in series a display switch increasing between the main power switch of existing display power supply system and the display unit, and by the closure of this display switch of human body infrared induction unit controls is set, so when the user of service leaves because of thing in use computer process, when this human body infrared induction unit does not have user in the certain distance as detecting before the display, then send control signal, make display switch disconnect, thereby make display unit close, thereby avoid the display unit power consumption of display and produce electromagnetic radiation.
For purpose of the present invention, structural attitude and function thereof are had further understanding, conjunction with figs. is described in detail as follows now:
[description of drawings]
Fig. 1 is the system block diagram of existing display power control system.
Fig. 2 is the system block diagram of display power control system of the present invention.
[embodiment]
Please refer to Fig. 2, system block diagram for display power control system of the present invention, display power control system 2 of the present invention may be implemented in the existing display, so that control the switch of the display unit of this display, thereby reach the purpose of power saving and reduction radiation, display power control system 2 of the present invention comprises the power-supply unit 20 of serial connection successively, main power switch 21, display switch 22 and display unit 24, wherein this power-supply unit 20 provides display required operating voltage, and main power switch 21 is in order to the connecting and disconnecting of the circuit between control power-supply unit 20 and the display switch 22, wherein this power-supply unit 20 is provided with same as the prior art with the structure of main power switch 21, can be a push switch as this main power switch 21, an improvement part of the present invention is to set up a display switch 22 between main power switch 21 and display unit 24, and this display power control system 2 also comprises a human body infrared induction unit 23, these human body infrared induction unit 23 1 input ends are connected with main power switch 21, the working power of this human body infrared induction unit 23 so is provided by this power-supply unit 20, and the output terminal of this human body infrared induction unit 23 is connected with display switch 22, with the switch of control display switch 22.In the specific implementation, this display switch 22 can be a transistor switching circuit, and the output terminal of this human body infrared induction unit 23 is connected with an input end of this transistor switching circuit.
After the user opens computer, after promptly activating main power switch 21, this power-supply unit 20 is connected with main power switch 21, this human body infrared induction unit 23 operating voltage are provided, whether these human body infrared induction unit 23 detectings have the user in the certain distance before display, if any then producing a trigger pip, thereby make this display switch 22 connect, so this power-supply unit 20, main power switch 21, display switch 22 and display unit 24 form a path, and so display unit 24 is started working.When the user continued to work before display, then the output terminal of this human body infrared induction unit 23 continued to keep a current potential, as noble potential, thereby keeps this display switch to be in closure state all the time, thereby made this display unit 24 keep operate as normal.And leave display for some reason during a period of time as the user, this human body infrared induction unit 23 can't detect when in the preceding certain distance of display the user being arranged, then output terminal becomes another current potential, as electronegative potential, so make display switch 22 disconnect, thereby cut off the power supply supply of this display unit 24, make this display unit 24 close, so avoid display unit 24 power consumptions of display and produce electromagnetic radiation.
