Abstract

The invention discloses a USB type computer watchdog apparatus and a control method thereof. The apparatus comprises a main processor module; the power end of the main processor module is connected with USB 5V of a built-in USB port of a computer mainboard through a power module; a data port of the main processor module is connected with USB_D- and USB_D+ of the built-in USB port of the computer mainboard through a communication module; and a control port of the main processor module is connected with a reset pin on the computer mainboard through a restart module. According to the apparatus and the control method thereof, the problem that a computer system needs to be manually restarted due to system exception or crash is solved, so that the labor maintenance cost is reduced and the economic benefit is increased.

Description

A kind of USB formulas computer watchdog device and its control method

Technical field

The present invention relates to computer motherboard peripheral hardware field, specifically a kind of USB formulas computer watchdog device and its Control method.

Background technology

Computer comes into the every field of social life, computer and the Internet daily work with common people Work, studying and living are closely bound up, in some special application scenarios, need computer long-time in the case of unattended Independent operating, but current computer system long-play occur deadlock, without response the problems such as, need manual intervention Restarting, had so not only affected the stability of computer product but also can increase cost of labor, in the urgent need to being improved.

The content of the invention

For the problem that above-mentioned prior art is present, it is an object of the invention to provide a kind of USB formulas computer watchdog dress Put and its control method, the apparatus structure is simple, processing technology is easy, submersible pump installing/dismounting is efficient and convenient, save and install Cost.

To achieve these goals, this USB formulas computer watchdog device includes：Main processor modules, the main process task The power end of module passes through the USB 5V connections of the internal USB mouth of power module and computer motherboard, the main processing block Data port passes through USB_D-, USB_D+ connection of communication module and computer motherboard internal USB mouth, the main processor modules Control mouth is by restarting the connection of the reset pin in module and computer motherboard.

Further, the main processor modules include：Primary processor and its peripheral circuit.

Further, the USB 5V of internal USB mouth are converted to 3.3V using low pressure difference linear voltage regulator by the power module.

Further, it is described to restart module specially audion cascode amplification driving circuit.

Further, the BOOT0 mouths of primary processor are grounded after serial ports burning program by the primary processor.

Further, the indicating lamp module is specially LED1 lamps by protective resistance R3 connection main processor modules.

Further, present invention also offers a kind of control method of USB formulas computer watchdog device, opens including house dog Status control module, setting restart delay time module, select monitoring task module.

Further, the power module, communication module are installed in a USB port and computer motherboard internal USB mouth connects Connect, it is described to restart the reset pin connection that module is separately provided on terminal and computer motherboard.

Compared with prior art, beneficial effects of the present invention are as follows：

1st, this device application single-chip microcomputer design, and devising independently of software system outside computer system, find to crash, Blue screen, computer is restarted without hardware during response, so as to increase the stability of computer product, can also be to for certain software system Working condition monitored, realize the automated surveillance to engineering equipment runtime.

2nd, this device efficiently solves calculating when for various unmanneds, the computer system of long-term automatic running The system exception of machine or deadlock need the problem manually restarted, and so as to reduce manual maintenance cost, increase economic benefit.

Specific embodiment

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in figure 1, this USB formula computer watchdog devices include：Main processor modules, the electricity of the main processing block Source passes through the USB 5V connections of the internal USB mouth of power module and computer motherboard, and the data port of the main processing block is led to USB_D-, USB_D+ connection of communication module and computer motherboard internal USB mouth is crossed, the control mouth of the main processor modules is led to Cross the reset pin connection restarted in module and computer motherboard.

When computer is installed, this device is inserted in the external USB port on mainboard, the terminal for restarting module is connected to meter Calculate the reset pin in mainboard；After serial ports burning program, the BOOT0 mouths of primary processor are grounded；The primary processor Communicated with computer operating system by USB HID protocols, judge whether operating system is normally run by communication protocol, found Communication protocol is abnormal or interrupts, then it is assumed that operating system is abnormal or crashes, and at this moment reseting module drags down mainboard reset pin level, Force mainboard to reset, restart computer, just normally can run after restarting the computer.

By the control software being installed on computer, the control to this USB formula computer watchdog devices is carried out, it is described Whether house dog open state control module can arrange and select to restart delay time module using this device, the setting and can set Put deadlock or certain software system without needing how long to carry out after response to restart, described select monitoring task module to be used for supervising The working condition of certain software system is controlled, after certain software system is selected, this device is by USB HID protocols and the software system System communication.
