Abstract
An impact detection device of a mobile communication terminal and a method thereof are provided to use impact data as objective data in determining whether a malfunction of the terminal is caused by a users mistake, when a terminal repair service is offered by detecting the impact put on the terminal and managing the impact data. An impact detection device of a mobile communication terminal comprises a mike, a mike amplifier, a level detector, a detection controller, and a memory. The mike, comprising a low power circuit, receives power. The mike amplifier amplifies an impact sound, inputted by the mike, by a certain gain. The level detector determines whether the level of the impact sound amplified by the mike amplifier is more than a preset level, and outputs an impact detection interrupt signal to the impact detection controller if the level of the impact sound is more than the preset level. The detection controller performs digital conversion for the impact sound if the level detector generates the impact detection interrupt, measures the impact level, determines a real impact by using a property change of a radio communication unit caused by a mechanical impact, and stores the impact data. The memory stores the impact data on the level of the impact sound detected by the detection controller.

Embodiment
With reference to the accompanying drawings embodiments of the invention are described in detail.
Fig. 1 is the example structure block diagram of the bumping and detecting device of the mobile communication terminal among the present invention.As shown in the figure, mobile communication terminal of the present invention comprises following several sections: microphone 11, constitute by low power circuit, and supply to power supply constantly; Microphone loudspeaker 12 is amplified to set gain to the collision sound by microphone 11 inputs; Whether grade detector 13, the grade of judging the collision sound that is amplified by microphone loudspeaker 12 be greater than the grade that presets, if just collision detection interrupt signal is sent to collide and detect control part 14; Collide and detect control part 14, grade detector 13 sends to collide and detects interrupt signal, measure its grade after just the grade of colliding sound being converted to number format, the machinery that utilizes wireless communication part 15 collides and the characteristic variations that takes place judges whether terminal collided, and storage collides data then; Memory 16, storage collide to detect control part 14 detected with collide the corresponding collision data of sound grade.
Microphone 11 is made of low power circuit, can supply to power supply constantly.When exterior of terminal was subjected to colliding, microphone 11 was sent to microphone loudspeaker 12 colliding sound, and microphone loudspeaker 12 is amplified to set grade to the collision sound of being imported by microphone 11.At this moment, microphone loudspeaker 12 generation of response collision sound fast.
Whether grade detector 13 judges the grade of the collision sound that is amplified by microphone loudspeaker 12 greater than the grade that presets, if greater than set grade, just collision detection interrupting information is sent to collide and detects control part 14.That is, filtered by grade detector 13 less than the collision sound that preestablishes grade, the grade detector can not detect interrupting information to colliding the 14 transmission collisions of detection control part like this.
Fig. 2 points out out the mobile communication terminal among the present invention to collide an embodiment action flow chart of detection method, as shown in the figure, it comprises following several steps: by driving microphone loudspeaker reception collision sound and with its amplification, detection level judges whether greater than set grade, if during, just measure the step of the characteristic variations of wireless communication part greater than set grade; The wireless parameter size that is determined during the characteristic variations of wireless communication part measured compares with the size that presets, if wireless parameter greater than preset big or small the time, the collision storage of now colliding sound is arrived the step of memory; When requiring the collision data are provided, the step of the collision data that are stored in the memory will be provided.
Suppose the user because of not noting applying the collision active force to mobile communication terminal, at this moment mobile communication terminal is carried out and is detected the function of colliding.
At this moment, mobile communication terminal is by driving microphone loudspeaker reception collision sound and amplifying, by the detection that collides the sound grade being judged whether the collision sound is greater than set grade.If during greater than set grade, mobile communication terminal is just measured the current channel of wireless communication part and Ec/Io that code is the base station signal of P/N, signal sensitivity, the phase change of PLL circuit, the lock-out state of PLL circuit.
If only judge collision by the size of simple collision sound, can think in-plant big noise by mistake collision, so mobile communication terminal is in order to judge whether collide sound is to collide the sound that takes place because of reality, measure the Ec/Io value of base station in fixing time, the Ec/Io value of base station is that the judgement terminal has or not the important benchmark that is subjected to the physics collision.
Frequency oscillator is built-in transistorized part, has the characteristic according to vibrations or collision its frequency of variation and phase place.So mobile communication terminal judges by the mensuration to the variation characteristic of the frequency number of frequency oscillator, phase place whether terminal is collided.
Judge when whether terminal is subjected to colliding, terminal is employed to be: the detected phase change of quality of base station signal (Ec/Io, frequency errors, business, time-division offset printing) or PLL phase detectors, lock-out state etc., by experiment, behind the judgment standard with the different separately collision degree of the wireless parameter decision that has been used, use selected judgment standard.
Mobile communication terminal determined wireless parameter size and fixed size compare, if the wireless parameter size greater than set when big or small, just with now collide the corresponding collision storage of sound in memory.Be stored in the collision data in the memory, will when judging the data of the collision size that mobile communication terminal is suffered, use.
Judge the result of the size of two wireless parameters, if wireless parameter less than set when big or small, mobile communication terminal then can not be identified as collision, ignores the collision data corresponding to above-mentioned collision sound.
When taking place to collide sound, mobile communication terminal becomes the collision of actual collision to store with data mode judging.In addition, service centre's request provides when colliding data, and mobile communication terminal provides the collision that is stored in memory data.The failure cause of terminal is judged with reference to colliding data by service centre, judges whether it is not note the fault that occurs because of the user.Service centre provides objective collision data to the user, thus prevention service dispute.
The as above mobile communication terminal among the present invention of Xiang Xishuominging has following effect:
Terminal is measured the suffered collision of terminal and is stored in the memory with data mode, when service centre's request provides data, terminal just offers service centre to the data of having stored, when service centre provides service to repair to the user, just these collision data there is unimpeachable objective data as the judgement user, thereby prevents to serve dispute in advance.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of claim of the present invention.
