Abstract
The utility model discloses an energy-saving control device which comprises a 5V power supply detection module and a power supply switch module, wherein the 5V power supply detection module is arranged in a host, and the power supply switch module is arranged in a power supply converter which is connected with an LCD (liquid crystal display). The energy-saving control device has the structural feature that the 5V power supply detection module is connected with the power supply switch module arranged in the power supply converter. When detecting 5V voltage of a computer system, the 5V power supply detection module transmits signals to the power supply switch module arranged in the power supply converter, starts the power supply connected with the power supply converter through the power supply switch module, and supplies power to the LCD; and when not detecting the 5V voltage of the computer system, the 5V power supply detection module transmits signals to the power supply switch module in the power supply converter, cuts off the power supply connected with the power supply converter through the power supply switch module, so as to ensure the power off between the power supply converter and the LCD and achieve zero power consumption. The energy-saving control device has the characteristics of simple structure and is convenient to use.
Description
Technical field:
The utility model relates to a kind of energy-saving control device, especially relates to the energy-saving control device as the AC Adapter of LCD.
Background technology:
At present computer has become the indispensable instrument of office, and energy consumption wherein receives increasing concern, and in the actual life, most of computer user all is the plug of display directly to be inserted on the power supply such as insert row, allows power supply be connected with display.In fact the led pilot lamp of display, the supply convertor that is connected with display are switched on, and no matter whether computer shuts down, the AC Adapter of LCD (Chinese name: supply convertor) with the led pilot lamp always at electric consumption.The display of different quality, the consumed power of the AC Adapter of LCD is different.
Summary of the invention:
At the problem that above prior art exists, the purpose of this utility model provides a kind ofly can judge the identification shut down of computer, and in time makes the led pilot lamp of LCD, LCD and energy-saving control device that the supply convertor that links to each other with LCD cuts off the power supply.
The purpose of this utility model is to realize like this, described a kind of energy-saving control device, comprise the 5V power supply detection module that is installed in the main frame, be located at supply convertor that LCD is connected in power switching module, to be described 5V power supply detection module be connected with power switching module in being located at supply convertor its design feature.
The beneficial effects of the utility model are: the utility model is judging by the 5V voltage condition in the identification computer system whether computer shuts down, and then decides the break-make of power supply by judged result.When 5V power supply detection module detects the 5V voltage of computer system, the power switching module of being located among the AC Adapter will be transmitted a signal to, open the power supply that is connected with AC Adapter by power switching module, give the LCD normal power supply, (generally being the shutdown situation) will send a signal to the power switching module among the AC Adapter when 5V power supply detection module can't detect the 5V voltage of computer system, cut off the power supply that links to each other with AC Adapter by power switching module, thereby guarantee AC Adapter and LCD no power, reach zero-power.The utlity model has characteristics such as simple in structure, easy to use.
Description of drawings:
Fig. 1 is a schematic block circuit diagram of the present utility model.
Among the figure: main frame 1,5V power supply detection module 2, LCD 3, supply convertor 4, power switching module 5.
Embodiment:
Below in conjunction with drawings and Examples the utility model is elaborated:
As shown in Figure 1, a kind of energy-saving control device described in the utility model, comprise the 5V power supply detection module 2 that is installed on main frame 1, be located at the AC Adapter (Chinese name: the power switching module 5 supply convertor 4) that is connected with LCD3,5V power supply detection module is used to power to the 5VSB power supply of the power supply of main frame, and 5V power supply detection module can adopt the metal-oxide-semiconductor of low pass; Its design feature is that (Chinese name: the power switching module 5 supply convertor 4) is connected described 5V power supply detection module 2 with being located at AC Adapter; When 5V power supply detection module detects computer system when having 5V voltage to produce, to transmit a signal to and be located at AC Adapter (Chinese name: the power switching module supply convertor), open (Chinese name: the power supply that supply convertor) is connected (as interleaving plate) by power switching module with AC Adapter, give the LCD normal power supply, (generally being the shutdown situation) will send a signal to the power switching module among the AC Adapter when 5V power supply detection module can't detect the 5V voltage of computer system, cut off and AC Adapter (Chinese name: the power supply that supply convertor) links to each other (as interleaving plate) by power switching module, thereby guarantee AC Adapter (Chinese name: supply convertor), reach zero-power with the LCD no power.
