Embodiment
Describe the preferred embodiments of the present invention in detail below in conjunction with accompanying drawing.
Referring to Fig. 1, the disposal route of computing system external connection equipment of the present invention comprises step:
Step 101 is installed the shock detection unit in computing system, be used for the vibrations of monitoring calculation system.The shock detection unit can be realized by shock sensor.If be configured the shock detection unit in the computing system, in the notebook computer that has active protective system (Active Protection System) at some, be provided with the hard disk vibration detecting system, then can utilize existing shock detection unit to realize the detection of computing system vibrations; If computing system does not have existing shock detection unit, the shock detection unit of then can be on computing system special installation detecting system vibrations.
Step 102, when the shock detection unit detected the vibrations generation, notifying operation system or driver were checked the connection status of external equipment.When external equipment being inserted or extracting operation, can cause the vibrations of computing system usually, the vibrations of computing system detect by the shock detection unit, and notifying operation system or driver check whether external equipment inserts or extract.The external equipment of checking can be predefined one or more external equipment, also can carry out the inspection of connection status to all external equipments of system's support.
The amplitude of the detected computing system vibrations in shock detection unit is different.If all will notify the connection status of checking pluggable equipment, the frequent generation that can cause the pluggable equipment connection status to be checked usually during detected very slight vibrations.A kind of mode of solution is the threshold value that a vibration amplitude is set, and when the shock detection unit detects the vibrations generation, judges that at first whether the amplitude of vibrations is greater than preset threshold, if, then check the connection status of pluggable equipment, otherwise, the connection status of pluggable equipment do not checked.Can avoid or filter out most of irrelevant vibrations like this, improve the efficient that connection status is checked.Under the situation that the connection status of a plurality of pluggable equipments need be checked, can set identical threshold value for them, also can different threshold values be set for each pluggable equipment.
Hard disk protection technology (APS, Active Protection System) is to be integrated in the notebook and to support user's configurable motion detector.Can constantly monitor moving and falling or similar incidents when taking place in the system of detecting of notebook computer, the operation that temporarily stops hard disk drive is to prevent some hard disk drive crash issue.When monitoring the vibrations of repeatability, in the time of for example in train or automobile, this detector can be regulated its susceptibility automatically and can not interrupt with the work that guarantees the user.Sudden shock is the vibrations that notebook computer falls suddenly, moves, brought when overturning, on chronergy, have sudden, stronger relatively on vibration amplitude.Active Hardisk protecting system can be measured the machine shock conditions immediately by the interior sensor of building in the machine; when notebook host takes place suddenly to shake or is mobile; the acceleration that sensor is experienced this burst can send a real-time signal to hard disk afterwards, allows hard disc magnetic head stop machine work to reduce the possibility of hard disk corruptions.Except sudden shock, when notebook computer was in the railway carriage that does not stop shaking or exercises in the bad automobile of road conditions, notebook computer can be along with vehicle body generation vibrations by a small margin.At this repeatability vibrations, the solution that active Hardisk protecting system provides is exactly temporarily to ignore the repeatability vibrations.Be embedded in sensor in the notebook computer after sensing the small size vibrations that notebook computer exists, can with the scope of these vibrations and roughly rule make record, when similar vibrations repeatability takes place, can help hard disk ignore the influence that this vibrations by a small margin produce by the setting option, to reduce the possibility of hard disk corruptions.
Utilize above-mentioned existing APS technology, after sensor arrives the acceleration of burst, can send a real-time signal, allow hard disc magnetic head stop machine work to hard disk.This real-time signal also can send to video card when sending to hard disk, trigger the detection of video card to external display, by the I on the reading displayed device
