Embodiment
Relevant preferred embodiment of the present invention, please be with reference to the built-in function calcspar of Fig. 1 display electronics assemblies 1, it is to comprise magnetometric sensor (Magneto Resistance Sensor, MR Sensor) 11, analog-digital converter (A/D Converter) 12, processor 13, storage element 14, and hard disk 15.
Above-mentioned magnetometric sensor 11 electrically connects with analog-digital converter 12.Analog-digital converter 12 also electrically connects with processor 13, and wherein analog-digital converter 12 is to see through a serial transmission interface to electrically connect with processor 13, and this serial transmission interface can be an IC bus.Processor 13 also electrically connects with storage element 14 and hard disk 15 respectively.
In present embodiment, electronic installation 1 is preferably a portable electronic devices, for example: mobile computer, contain the Portable music player of hard disk or include PDA(Personal Digital Assistant) of hard disk etc.In present embodiment, magnetometric sensor 11 is preferably three magnetometric sensors, and magnetometric sensor 11 also can be the magnetometric sensor of three magnetometric sensors or other pattern in other embodiments.In present embodiment, storage element 14 is preferably a buffer, and in other embodiments, storage element 14 can be an impact damper, non-voltile memory or volatile memory etc.In present embodiment, hard disk 15 is preferably a micro hard disk (Micro Disk Drive).
In Fig. 1, magnetometric sensor 11 is in order to provide the magnetic field intensity of its sensing, because in the present embodiment, magnetometric sensor 11 is three magnetometric sensors, and Gu Qihui provides the magnetic field intensity of three axles (X, Y, Z) component to give analog-digital converter 12.Analog-digital converter 12 is after the magnetic field intensity that reception magnetometric sensor 11 is provided, and analog-digital converter 12 is converted to magnetic field intensity digital sensing value and exports processor 13 to.
Above-mentioned storage element 14 stores plural default value (for example: first default value (P1), second default value (P2), the 3rd default value (P3)).13 space displacements of judging electronic installation 1 according to these default values and digital sensing value of processor; if electronic installation produces a space displacement (translation or fall) (0.75 meter) in a Preset Time (for example: 1 second) in, processor can send controlling signal and control hard disk 15 startup protection mechanisms.The relevant treatment how relevant processor 13 is judged please be with reference to following explanation.
Above-mentioned processor 13 can be handled the digital sensing value of one of them or two axle components, perhaps in regular turn/and with the digital sensing value to three axle components is handled.Following will with 13 pairs of processors wherein the situation handled of component illustrate.After processor 13 received digital sensing value (S1), 13 pairs of digital sensing value of processor (S1) were handled with first default value (P1), to obtain a difference (B1).Then processor 13 compares the difference (B1) of digital sensing value (S1) with first default value (P1) again with second default value (P2) and the 3rd default value (P3).
If difference (B1) is less than second default value (P2), then represent electronic installation 1 may be in normal spatial movement (for example: portable apparatus is being carried by the user and walking), electronic installation 1 also may be stationary state, that is electronic installation 1 may be placed on the desk and be not moved, shown in Fig. 2 a.At this moment, processor 13 is still kept its normal running, and hard disk 15 this moment if operate, then can be not influenced.For example: in Fig. 3 a, hard disk 15 is a hard disk, and it is to include disc 151, magnetic head 152, and transfer arm 153, and wherein magnetic head 152 is mounted on an end of transfer arm 153.Because this moment, hard disk carried out data access, so transfer arm 153 can be controlled by the hard disk control chip, carried out data access with the appropriate location that moves on the disc 151.For processor 13, because the difference (B1) of digital sensing value (S1) and first default value (P1) is less than second default value (P2), so processor 13 is still kept its normal running, and hard disk will be proceeded its data access.
If difference (B1) is greater than second default value (P2), and on behalf of electronic installation 1, difference (B1) then to produce violent space displacement less than the 3rd default value (P3), and for example: electronic installation 1 may be dropped toward the floor by a desktop, shown in Fig. 2 b.At this moment, processor 13 produces a controlling signal, and processor 13 transfers to hard disk 15 with this controlling signal, to start protection mechanism.For example: in Fig. 3 b, this moment, hard disk may carry out data access, so transfer arm 156 moves to the appropriate location on the disc 154, to carry out data access.For processor 13, because difference (B1) is greater than second default value (P2), and difference (B1) is less than the 3rd default value (P3), so processor 13 produces controlling signal, and it is delivered to hard disk, make the control chip control transfer arm 156 of hard disk leave the zone of disc 154, for carrying out magnetic head 155 returns, cause magnetic head 155 and disc 154 to collide mutually with the impulsive force of avoiding electronic installation 1 to produce, and then cause data to move and lose or hard disk generation fault because of violent space displacement.
If difference (B1) is greater than the 3rd default value (P3), then represents the electronic installation 1 may be, and then make that the magnetic field intensity of 11 sensings of magnetometric sensor is excessive near magnetisable material.For this kind situation, processor 13 will be kept its normal running and can not start anti-vibration protected mechanism.
Certainly, the above-mentioned magnetic field intensity that how to see through 11 sensings of magnetometric sensor about processor 13 judges whether electronic installation 1 has strenuous exercise, is only to be a preferred embodiment.In other embodiments, storage element 14 also can store comparison list, this table of comparisons has a plurality of typical values, and each typical value is represented the desired quantity of electronic installation 1 under various motion states (for example: static, normal space displacement or violent space displacement etc.).Therefore; processor 13 is after receiving digital sensing value; it is this numerical digit sensing value can be compared this table of comparisons, and to find out the immediate typical value of digital sensing value, processor 13 is kept its normal running or the anti-vibration protected mechanism of control hard disk 15 startups according to its typical value of finding out again then.
By above explanation as can be known; the present invention utilizes magnetometric sensor to come detection. electronics whether to be in violent space displacement; if; then see through processor earlier controlling signal is provided; so that hard disk can initiatively carry out anti-vibration protected mechanism earlier; reduce the chance of hard disk whereby, and can increase the hard disk degree of stability, prevent that data from losing and need not to expend a large amount of inner spaces and provide mechanical type shockproof because of the impulsive force fault.
The foregoing description only is to give an example for convenience of description, and the interest field that the present invention advocated should be as the criterion so that the protection domain of claim is described certainly, but not only limits to the foregoing description.
