Abstract

The utility model discloses a computer power -off control device based on USB interface, the device comprises shutdown module, single -chip module, USB module, control end, and the control end sends to single -chip module through the USB module and shuts down or delay shutdown's control signal, and single -chip module sent the instruction of shutting down to the shutdown module after receiving the shutdown control signal that the control end sent, and shutdown module control computer shuts down. Use the device, can solve the user through operating system or management system carry out the operation back no. 1 of shutting down fix time in the computer successfully do not close machine -hour, this controlling means can force to shut down voluntarily, can prevent effectively that the power consumption that leads to the fact because of not shutting down is extravagant, can also prevent simultaneously not shut down the computer that shuts down perhaps use for a long time leads to the fact that components and parts wear out, generate heat because of forgetting, short circuit etc. Causes accidents such as conflagration. In addition, to the computer of needs through authorizing ability normal use, the device is not obtaining delay shutdown instruction back, can the positive closing computer yet.

Description

A kind of USB interface-based computer shutdown control device

Technical field

The utility model is related to a kind of USB interface-based computer shutdown control device.

Background technology

At present, computer has become our daily lifes and all indispensable equipment that works, and in routine use, has Shi Mingming has performed in an operating system power-off operation, computer and has also pointed out shutting down, but calculates after waiting as long for Machine does not still shut down, and causes the problems referred to above it is usually because Computer Hardware Malfunctions, operating system failure or infection virus etc.. Also many people usually when perform power-off operation after just leave computer, take for computer and have been switched off, object computer is simultaneously Do not shut down.The problems referred to above not only cause electricity consumption to waste, and because computer long-time start cause components and parts heating, it is aging, short Road, shortens the computer life-span, while being also possible to initiation fire.

Utility model content

Power-off operation has been performed in order to solve user, but the problem that computer does not shut down, and the utility model carries A kind of USB interface-based computer shutdown control device is supplied, the device can be automatically strong in the unsuccessful shutdown of operating system System is shut down computer；For the computer for needing to be used through mandate, the device can not receive delay switching-off control yet Positive closing computer during signal processed.

The utility model solves the technical scheme that its technical problem adopted：A kind of USB interface-based calculating office Machine control device, the control device is by module of shutting down（1）, one-chip computer module（2）, USB module（3）, control end（4）Composition.

Above-mentioned USB interface-based computer shutdown control device, described USB module (3) the standard USB of being provided with connects Mouth is connected with USB interface of computer.

Above-mentioned USB interface-based computer shutdown control device, described shutdown module（1）It is provided with two groups of shutdown Control line, two per group, one group of power switch interface for being connected to computer motherboard, another set connection computer switch is pressed Key.

Above-mentioned USB interface-based computer shutdown control device, described control end（4）By USB module（3）To One-chip computer module（2）The control signal of transmission is at least shut down and two kinds of delay switching-off.

Above-mentioned USB interface-based computer shutdown control device, described one-chip computer module（2）Have standby clocking Unit, start after electrifying startup it is standby clock, stand-by time is set or the delay switching-off signal that passes through control end by user Setting；When standby period does not receive delay switching-off control signal or arrival time, to shutdown module off signal is sent.

Above-mentioned USB interface-based computer shutdown control device, described shutdown module（1）Using relay-type Number be SRD-05VDC-SL-A；Described one-chip computer module（2）Single-chip microcomputer model STC15F104W；Described USB module （3）USB chip models be CH340G；Described control end（4）For existing computer operating system or management system.

The beneficial effects of the utility model are：Using this USB interface-based computer shutdown control device, user is led to If crossing operating system or management system performing the unsuccessful shutdown of computer in certain hour after power-off operation, the control device can Automatic forced shuts down, and can effectively prevent the electricity consumption caused because not shutting down from wasting, while can also prevent because forgetting to shut down or counting Calculation machine does not shut down to use for a long time and causes component aging, heating, short circuit etc. to cause the accidents such as fire.Additionally, for needing Jing Cross and authorize the computer that could normally use, the device, also can positive closing computer after delay switching-off instruction is not obtained.

Description of the drawings

The utility model is further illustrated with reference to the accompanying drawings and examples.

Fig. 1 is the utility model schematic diagram；

1. shutdown module in figure, 2. one-chip computer module, 3.USB modules, 4. control end.

Specific embodiment

As shown in Figure 1, this kind of USB interface-based computer shutdown control device, by shutdown module（1）, single-chip microcomputer mould Block（2）, USB module（3）, control end（4）Composition.USB module is provided with standard USB interface and connects with computer motherboard USB interface Connect, control end sends shutdown or delay switching-off control signal by USB module to one-chip computer module, and one-chip computer module is according to control The control signal at end is controlled to module of shutting down；Shutdown module is provided with two groups of connecting lines, 2 per group, computer is connected respectively The power switch interface and computer cabinet power switch button of mainboard；

During concrete application, the switch key connecting line for being inserted in computer motherboard POWER SW power switch interfaces position is pulled out Changing-over is played to the POWER-B interfaces of control device shutdown module, then shutdown module POWER-A and the POWER of computer motherboard SW power switch interfaces connect, and the connecting line of USB module is finally connected to the USB interface of computer motherboard, and user is based on Calculating machine host power switch makes the USB module of computer booting, control device obtain power initiation, and control device is entered after starting Holding state, if the instruction duty for receiving control end performs dependent instruction under holding state, if standby period receives control End shutdown command processed or when reaching stand-by time set in advance, the one-chip computer module in control device is just sent out to shutdown module Go out shutdown command, the control computer shutdown of shutdown module.Computer enter operating system after, user just can by control end to USB module sends shutdown, delay switching-off instruction and realizes computer shutdown control.

According to above-described embodiment, the utility model just can be well realized.
