Abstract
The invention discloses a drop and power-down protection method for handheld terminals. The method includes the steps: a sensor module capable of sensing drop state is used to detect the state of a handheld terminal; when a processor module is detected and a system being in the drop state is confirmed, input-output parts and wireless connection parts having high power consumption are shut off or adjusted in the low-power state. Therefore, at the moment that the battery is disconnected, a large capacitor of a power supply module of the handheld terminal can ensure power supply of the whole system, and power-down protection at the moment of dropping is achieved.
Description
Technical field
The present invention relates to the power-off protection method of handheld terminal in falling process, relate in particular to and a kind ofly by implant the sensor assembly can perception falling in handheld device, detect the power-off protection method falling.
Background technology
Handheld terminal, in carrying process, unavoidably has situation about falling and occurs.At handheld terminal, land in collision process, likely can cause the moment connecting between battery connector and battery terminal to disconnect, although power supply circuits part may have large electric capacity on the circuit board of handheld terminal, but the capacity of electric capacity is limited after all, when handheld terminal (suppose displaying video, send a telegram here and shake, express network access etc.) in situation under the state of strong load operation, power supply electric capacity is understood rapid power consumption and voltage drop, thereby causes handheld terminal power down.Therefore, we need a kind of circuit protection technology, evade this situation of falling power down.
Summary of the invention
Power-down conditions for handheld terminal when the drop impact, goal of the invention of the present invention is to provide a kind of method that realizes power down protection by implant sensor assembly that perception falls in handheld terminal.
Goal of the invention of the present invention is achieved by the following technical solution:
A kind of handheld terminal fall power-off protection method; described the method is carried out sense movement state by the built-in sensor assembly of handheld terminal; when the processor of handheld terminal detects and confirms that motion state is when falling; by Temporarily Closed power consumption parts; thereby make the large electric capacity of power pack can the longer time of continuous firing; until battery connector and battery terminal reconnect, thereby played preferably power down protection effect.The sensor assembly can perception falling, can be acceleration transducer, gyroscope, and the combination of one or more in geomagnetic sensor, also may realize detection and the perceptional function of falling with future various novel transducers and combination thereof.
Handheld terminal comprises 5 major parts, comprises supply module, sensor assembly, processor module, inputoutput unit group, wireless connections parts group.Supply module is mainly used to divide and power to the electric control part of whole handheld terminal; Sensor assembly is used for sensing SOT state of termination; Inputoutput unit group includes but not limited to display unit (as LCD, projecting apparatus etc.), and input module (comprises keyboard, touch screen, make a video recording first-class), output interface (HDMI, MHL, Slim port etc.) and audio-frequency module (as Codec, audio frequency PA, loudspeaker etc.); Wireless connections parts group includes but not limited to BT, WIFI/WAPI, WiMAX and mobile communication function module (comprising 2G, 3G, 4G and following Novel movable communication standard); Processor module is comprised of CPU and storage system, mainly completes computing, logical process function and to the detection of these other functional modules of handheld terminal with control function.
A kind of handheld terminal fall power-off protection method, the method to realize principle as follows: sensor assembly is when motion state being detected, notification processor module, processor module is come and is judged that according to the setting parameter of system whether hand terminal system is in falling state by the output of detecting sensor, when in falling in state, processing module first records current output block group and wireless connections parts group's state, then by output block and wireless connections parts are closed or make it enter low power consumpting state, simultaneous processor module can also reduce operating frequency and enter low power consumpting state, thereby not power down of system when guaranteeing to fall, after processor module detects handheld terminal and fallen, it can also carry out recovering state according to the final state of pre-recorded output module and wireless connections module.

Embodiment
How below in conjunction with accompanying drawing, further illustrate the present invention realizes:
Embodiment
As shown in Figure 1, the present invention is in order to explain conveniently, the parts of handheld terminal 1 are divided into five major parts (note: handheld terminal may also comprise and the incoherent miscellaneous part of the inventive method and module, this five major part only, as signal Module Division, is mainly used to set forth principle of the present invention), comprising: supply module, sensor assembly, processor module, inputoutput unit group, wireless connections parts group.Wherein, supply module 2 is used for powering to whole handheld terminal 1; Sensor assembly 3 is used for detecting the motion state of handheld terminal 1; Processor module 4 is used for operating software system, and the exercise data simultaneously obtaining by sensor assembly 3 carries out handheld terminal and whether falls state and judge; Inputoutput unit group 5 and wireless connections parts group 6, as the larger part of power consumption,, need to be turn-offed operation or be made it enter low-power consumption mode by processor at handheld terminal when falling state.
As shown in Figure 2, the present invention for be when handheld terminal falls, when colliding ground or other problems, supplying cell 7 and handheld terminal connector contact 8 likely can be by being closed into disconnection in the moment of collision, in of short duration time course of this time, battery cannot be powered to handheld terminal.In general, the power pack of handheld terminal, have supply module electric storage device 9 and power by 10 pairs of whole handheld terminals of power supply output contact, thereby can also normally work the moment that assurance system disconnects at battery.Because the energy that the supply module electric storage device 9 shown in Fig. 2 is stored is relatively limited, handheld terminal is when high load capacity operates, as BT/WIFI/WIMAX transfer of data, watch audio frequency and video, calling vibration, in the process that one or more states such as telephone relation move simultaneously, the electric energy of supply module electric storage device 9 will be depleted rapidly, and system is power down immediately.
According to the situation of the described handheld terminal power down that may occur above; power-off protection method of the present invention and flow process be as shown in Figure 3: hand system is first in normal condition; when suddenly because certain event causes handheld terminal when falling state; sensor assembly 3 can detect this motion state; and notify processor module 4 by terminal; processor module 4 collects after various motion state data by sensor assembly 3; by built-in software algorithm, judge; if judgement is not fallen; get back to normal condition, do not carry out any processing.If judgement handheld terminal is in falling state, processor module 4 first records current inputoutput unit group and wireless connections parts group's operating state (close or whether low power consumpting state) and own state itself, then set and fall sign, then reduce the level of power consumption of the power consumption parts in inputoutput unit group 5 and wireless connections parts group 6 or close this two parts groups' part or all of function, if processor module 4 is supported low-power consumption mode, processor enters low power consumpting state subsequently, ceaselessly whether cycle detection handheld terminal has fallen simultaneously, when having fallen, System Cleaning falls sign, by the system state data of preserving, recover inputoutput unit group 5 and wireless connections parts group's 6 state simultaneously, if processor module 4 itself is placed in low power consumpting state, also can carry out recovering state.
