Description
Technical field
The invention relates to a kind of portable device and control method thereof with electronic control system, particularly about a kind of portable device with electronic control system and control method thereof of preventing acceleration abnormal damage motor drive that is applied to notebook computer.
Background technology
At present, MP3 walkman, mobile phone, PDA and notebook computer etc. portable device becomes the indispensable daily necessities of modern gradually, the frequency that these electronic equipments of carrying not only use is quite high, be not subject to occasion and the time of use yet, use on the car in may be in action, may when road is walked, use, even may in violent motion process, use this product.Therefore also in the process of using these portable devices, tend to because user's carelessness or unusual action cause element collision or the friction of device interior, and cause the damage of equipment.Acknowledged causes the device of damage easily because collide or fall in general electronic equipment, just belongs to hard disk (HDD).Also therefore, passing technology and solution all are to protect this device.The most practice has both direction: one namely is to utilize padded coaming or the buffer structure that is coated on outside the HDD, the impact when reducing collision; Second it is to utilize electronically controlled method to protect action.
In electronically controlled method, US Patent No. 5,227,929 have disclosed a kind of protection mechanism and system protects hard disk (Hard Disk) avoid the being collided damage of impact (shock).The detecing element that adopts in this patent is a three axis accelerometer (three-axis accelerometer); after processor processing signal; system is issued an order, be used for the read/write head of playback (park) hard disk can not be subject to the collision of read/write head with the disc of protection HDD.
And TaiWan, China patent I256053, I280570, I292876 have disclosed similar solution successively.Adopt the acceleration detector that the action signal is provided in the I256053 case, and with processing unit analog signal is converted to digital signal, when this action surpassed threshold value, processing unit can cut off the power supply of hard disk, allows hard disk decommission.The I280570 case has then disclosed a kind of holding circuit, comprised can the action of sensing X/Y diaxon sensing cell and CPU (central processing unit), when X-axis when moment, displacement reached a certain degree with Y-axis, CPU (central processing unit) can be carried out the protection of hard disk and move.The sensor operation that this patent is mentioned is detecting X-axis and Y-axis moment displacement, is not the component of X/Y/Z axle, variation that neither acceleration, so the scope of this patent be detect X-axis and Y-axis diaxon with and displacement.The I292876 case has then proposed a kind of in conjunction with three shaft control methods of electronic installation with the control module, different from other front case is, whether the method for detecting that this case adopts is not to calculate threshold value to overrun, but utilize the mode of database comparison to find out data difference, be used for judging whether carrying out the control signal with the control electronic installation.The disclosed scope of this case is not mentioned Electronic Control and whether is used for stopping the hard disk action, yet this electronic control method can also be as the solution of protection hard disk.
