Abstract
A laptop falling-off protecting device is characterized in that the laptop falling-off protecting device is connected to a USB interface used for supplying electricity; by means of a chip USB2I2C which switches into a bus I2C from a USB universal serial bus, a Freescale three-axis acceleration sensor MMA7667 is connected to the I2C, the sensor can accurately sense space acceleration and transmit collected data to an operation system of a computer through the USB universal serial bus by the USB2I2C, reading and writing of a hard disk are closed when the MMA7667 senses sudden acceleration by matching laptop side software, so that a head enters a stopping area forcibly, and the hard disc is protected. When the sudden acceleration is sensed, reading and writing of the hard disk are closed, so that the head enters the stopping area forcibly, the hard disc is protected, falling off occurring possibly is forecast, and loss is reduced to the minimum.
Description
Technical field
Protection to hard disk when this technology is fallen mainly for notebook by the monitoring to complete machine acceleration, is closed immediately the read-write of hard disk in the time falling beginning, and magnetic head is recovered to stop zone, protection hard disk.
Background technology
Notebook is more and more used in industry at present; commercial use, the storage volume of hard disk is also increasing, but accidental fall usually shines into irreversible damage to the hard disk of reading and writing; so do not change the existing hardware configuration of notebook for one, the device that can protect again hard disk is very necessary.
Summary of the invention
The hard disk that the object of the invention is the notebook falling meeting accident is protected.
Technical scheme of the present invention is: notebook computer fall protection device, it is characterized in that: 1 pin of the J1 of USB interface is connected to the 8 pin VCC of USB2I2C, the 2 pin D-of J1 are connected to the 11 pin UD-of USB2I2C, the 3 pin D+ of J1 receive the 10 pin UD+ of USB2I2C, and the 4 pin GND of J1 are connected to the 12 pin GND of USB2I2C; Between the 8 pin VCC of USB2I2C and the 3 pin VCC of MMA7667, meet 3.3v voltage stabilizing diode D1, between the 23 pin SCL of USB2I2C and the 1 pin SCL of MMA7667, meet 3.3v voltage stabilizing diode D2, between the 24 pin SCL of USB2I2C and the 2 pin SDA of MMA7667, meet 3.3v voltage stabilizing diode D3.Notebook computer fall protection device is connected in USB interface; from USB interface power taking; utilize this USB USB (universal serial bus) of USB2I2C to turn I2C bus chip; on I2C, connect Freescale MMA7667 3-axis acceleration sensor; this sensor is aware space acceleration accurately; and by USB2I2C, the data that collect are passed to the operating system of computer by USB USB (universal serial bus); coordinate notes local terminal software; when MMA7667 perceives the acceleration of a burst; close disk read-write; allow magnetic head is forced to enter stop zone, protection hard disk.
The beneficial effects of the utility model: do not need to transform any notebook inner structure, USB interface is directly powered, and does not need extra single-chip microcomputer, also can use the huge computing advantage of notebook CPU energy-conservation time, contingent falling predicted, loss is dropped to minimum.
Accompanying drawing explanation
Fig. 1 is notebook fall protection device circuit figure.
In figure, 21:USB interface 22:USB turns I2C chip 23:MMA7667 3-axis acceleration sensor.
Embodiment
Embodiment 1: when notebook is normally worked, while not falling, notebook fall protection device reported data is normal, and notebook hard disk is is normally read and write.
Embodiment 2: in the time of notebook accidental fall, notebook fall protection device reported data is abnormal, generation is fallen in prediction, and notebook hard disk cuts out read-write, and magnetic head is got back to stop zone.
