Embodiment
Below in conjunction with drawings and embodiments, the present invention is described in detail.
Consult Fig. 2, in an execution mode of the folding lid condition detection method of mobile terminal of the present invention, comprise the steps:
Step S201: the electronic compass sensor of mobile terminal detects current magnetic field intensity to obtain current magnetic field strength information.
The mobile terminal of present embodiment is type flip mobile terminal.Along with the development of mobile terminal technology, electronic compass sensor has become the standard configuration of mobile terminal especially intelligent mobile terminal, it is mainly used for the GPS navigation of mobile terminal, by detecting the direction in magnetic field of the earth, then the angle of the geographical south poles of mobile terminal and the earth is judged, and then determine the orientation of mobile terminal, thus be reached for the object that user provides direction.In addition, electronic compass sensor is restricted for the magnetic field intensity of operational environment, the electronic compass sensor range of such as Hall type is generally 20 Gausses or 2.4 teslas, if the magnetic field intensity of operational environment exceedes this range, direction, magnetic field of the earth then detected by electronic compass sensor is by incorrect, namely cannot carry out GPS navigation, therefore electronic compass sensor also has the ability detecting magnetic field intensity.And the work that present embodiment utilizes electronic compass sensor to detect magnetic field intensity just in order to replace traditional Hall magnetic field transducer to obtain mobile terminal and uncap or closing lid time magnetic field intensity information.
Particularly, electronic compass sensor and magnet or other magnetic devices are placed in two lids of mobile terminal respectively, and such as electronic compass sensor is placed in the lower cover of mobile terminal, and magnet is then placed in the upper cover of mobile terminal.Under the mating reaction of magnet, when the upper cover of mobile terminal and lower cover away from or near time, electronic compass sensor detects the magnetic field intensity in X-axis, Y-axis and Z-direction, and is added the absolute value of the magnetic field intensity in X-axis, Y-axis and Z-direction with the value obtaining current magnetic field intensity.Wherein, electronic compass sensor is in the process detecting the magnetic field intensity in X-axis, Y-axis and Z-direction, first the magnetic field intensity information on each axle of obtaining to extract the directional information (i.e. positive negative direction) of the magnetic field intensity of each axle, and obtains the absolute value of the magnetic field intensity of each axle.
Step S202: the folding lid state of the current magnetic field strength information identification mobile terminal that the processor of mobile terminal obtains according to electronic compass sensor, when the value of the current magnetic field intensity corresponding to current magnetic field strength information that wherein electronic compass sensor obtains is greater than setting threshold, recognition result is that mobile terminal is in closing lid state, otherwise mobile terminal is in uncapped state.
First preset a magnetic field intensity threshold value, be called above-mentioned setting threshold values, the value of magnetic field intensity corresponding when can be critical angle by the angle between upper cover and lower cover is set to this setting threshold.Such as, critical angle is set to 90 degree, the value of namely corresponding when the angle that upper cover and lower cover are formed is 90 degree magnetic field intensity is set to setting threshold, and think that when the angle that upper cover and lower cover are formed is less than 90 degree mobile terminal is in closing lid state, now the value of current magnetic field intensity is greater than setting threshold, think that mobile terminal is in uncapped state when the angle that upper cover and lower cover are formed is not less than 90 degree, now the value of current magnetic field intensity is not more than setting threshold.In other words, think when the angle between upper cover and lower cover is less than critical angle that mobile terminal is in closing lid state, otherwise be in uncapped state.In other implementations, this setting threshold also can set according to the range of electronic compass sensor, does not limit herein.
According to the relative theory of magnetic flux, when upper cover and lower cover are the closer to (i.e. electronic compass sensor and magnet the closer to), namely more hour, magnetic flux is larger, and the current magnetic field intensity that electronic compass sensor detects is also larger for the angle between upper cover and lower cover; When upper cover and lower cover are more away from (i.e. electronic compass sensor and magnet gradually away from), when the angle namely between upper cover and lower cover is larger, magnetic flux is less, and the current magnetic field intensity that electronic compass sensor detects is also less.Therefore, when the value of the current magnetic field intensity corresponding to the current magnetic field strength information that electronic compass sensor obtains is greater than setting threshold, illustrate that the angle between upper cover and lower cover is less than critical angle, now processor identification mobile terminal is in closing lid state, otherwise processor identification mobile terminal is in uncapped state.And after processor identification mobile terminal is in closing lid state, if the previous state of mobile terminal is uncapped state, then notify to make mobile terminal enter standby mode by main program turning-off mobile terminal screen, otherwise keep closing lid state.And after processor identification mobile terminal is in uncapped state, if the previous state of mobile terminal is closing lid state, then notify that main program opens mobile terminal screen, make mobile terminal enter normal Activate pattern.
Further, in present embodiment, the current magnetic field strength information that electronic compass sensor obtains is the flag bit of its register.The step of now electronic compass sensor acquisition current magnetic field strength information comprises: electronic compass sensor judges whether the value of current magnetic field intensity is greater than setting threshold, if, then make the flag bit of the register of electronic compass sensor for " 1 ", otherwise be " 0 ", flag bit is current magnetic field strength information.Therefore, processor, before the folding lid state of the current magnetic field strength information identification mobile terminal obtained according to electronic compass sensor, first reads the flag bit of the register of electronic compass sensor, to obtain current magnetic field strength information.When the flag bit of the register read is " 1 ", illustrate that the value of the current magnetic field intensity corresponding to current magnetic field strength information is greater than setting threshold, now processor identification mobile terminal is in closing lid state; When the flag bit of the register read is " 0 ", illustrate that current magnetic field strength information shows that the value of current magnetic field intensity is not more than setting threshold, now processor identification mobile terminal is in uncapped state.Therefore, only processor need be made periodically to read the flag bit of the register of electronic compass sensor and the folding lid state of identifiable design mobile terminal.
It should be noted that, the mobile terminal of present embodiment can also be slide type mobile terminal, now the setting threshold of the magnetic field intensity of mobile terminal then can set according to the distance between upper cover and lower cover, when arriving critical distance by the distance between the bottom of upper cover and the bottom of lower cover, corresponding magnetic field intensity is set to setting threshold, and the distance between the bottom and the bottom of lower cover of upper cover thinks that mobile terminal is in closing lid state when being less than critical distance, now current magnetic field intensity is greater than setting threshold, think when distance between upper cover and lower cover is not less than critical distance that mobile terminal is in closing lid state otherwise is in uncapped state.Therefore, when the value of the current magnetic field intensity corresponding to the current magnetic field strength information that electronic compass sensor obtains is greater than setting threshold, illustrate that the distance between the bottom of upper cover and the bottom of lower cover is less than critical distance, the processor identification mobile terminal of mobile terminal is in closing lid state, otherwise identifies that mobile terminal is in uncapped state.

Particularly, the absolute value of the magnetic field intensity in X-axis, Y-axis and Z-direction for detecting the magnetic field intensity comprised in X-axis, Y-axis and Z-direction, and is added with the value obtaining current magnetic field intensity by electronic compass sensor 301.In present embodiment, the current magnetic field strength information that electronic compass sensor 301 obtains is the flag bit of the register of electronic compass sensor 301.Electronic compass sensor 301 is after the value obtaining current magnetic field intensity, judge whether the value of the current magnetic field intensity obtained is greater than setting threshold, if so, then make the flag bit of its register for " 1 ", otherwise be " 0 ", this flag bit is current magnetic field strength information.Namely, when flag bit is " 1 ", illustrate that the value of the current magnetic field intensity corresponding to current magnetic field strength information is greater than setting threshold; When flag bit is " 0 ", illustrate that the value of the current magnetic field intensity corresponding to current magnetic field strength information is not more than setting threshold.Therefore, processor 302 identifies the folding lid state of mobile terminal by the flag bit of the register reading electronic compass sensor 301, when the flag bit read is " 1 ", the recognition result of processor 302 is that mobile terminal is in closing lid state, when the flag bit read is " 0 ", the recognition result of processor 302 is that mobile terminal is in uncapped state.
