Description

Portable device and control method thereof with electronic control system
Technical field
The invention relates to a kind of portable device and control method thereof, particularly damage the portable device with electronic control system and the control method thereof of motor drive unusually about a kind of acceleration that prevents that is applied to notebook computer with electronic control system.
Background technology
At present, MP3 walkman, mobile phone, PDA and notebook computer or the like 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 the occasion and the time of use yet, use on the car in may be in action, use in the time of may on road, walking, 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 the element collision or the friction of device interior, and cause the damage of equipment.In general electronic equipment, generally acknowledge the easiest device that causes damage because collide or fall, just belong to hard disk (HDD).Also therefore, passing technology and solution all are to be used for protecting this device.The most practice has both direction: one promptly 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, U.S. Pat 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 is adopted in this patent is a three axis accelerometer (three-axis accelerometer); after the processor processing signal; system is issued an order, be used for the read/write head of playback (park) hard disk can not be subjected 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 a 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 three shaft control methods in conjunction with electronic installation and control die set, different with other preceding case is, whether the method for detecting that this case adopted 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 to carry out controlling 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.
Summary of the invention
