Description of drawings
Fig. 1 is the connection diagram of each functional module among the present invention program.
Embodiment
The present invention program is provided with digital compass module in handheld device, obtain the magnetic direction data by this digital compass module; And the magnetic direction display module is set, by this magnetic direction display module the magnetic direction data are converted to graphic display information, and the graphic display information that obtains are presented on the screen of handheld device.
Below in conjunction with drawings and the specific embodiments the present invention program is described in further detail.
Figure 1 shows that the connection signal of each functional module that realizes direction recognition function in the handheld device, digital compass module 101 is connected with magnetic direction display module 102.Digital compass module 101 sends to magnetic direction display module 102 with the magnetic direction data that obtain, magnetic direction display module 102 generates graphic display information according to the magnetic direction data that obtain, and this graphic display information is presented on the screen of handheld device.
Wherein, digital compass module 101 is by orthogonal two Magnetic Sensors 103,104, and magnetic direction computing module 105 is formed.Magnetic Sensor specifically is made of magneto-resistor parts and Hall parts.Two Magnetic Sensors are connected with magnetic direction computing module 105 respectively, and digital compass module 101 is connected with magnetic direction display module 102 by magnetic direction computing module 105.Magnetic Sensor 103,104 is connected with magnetic direction computing module 105 respectively, the potentiometer that magnetic direction computing module 105 records according to these two Magnetic Sensors is calculated the drift angle of magnetic direction and certain Magnetic Sensor, and this drift angle sent to magnetic direction display module 102,102 of magnetic direction display modules are object of reference with this Magnetic Sensor, and show magnetic direction according to this drift angle in the screen of handheld device.
Specifically, when handheld device had rotation, the magnetic flux by two Magnetic Sensors all can change, and produced magnitudes of voltage at two Magnetic Sensors respectively.At rotational angular velocity one regularly, when Magnetic Sensor 104 and magnetic direction when parallel, Magnetic Sensor 104 magnetic flux change maximums, the magnitude of voltage maximum that is produced, certainly, according to the direction that is provided with of Magnetic Sensor, the magnitude of voltage that is produced may be a maximum positive voltage, also may be peak suction, Magnetic Sensor 103 magnetic flux change minimums, the magnitude of voltage that is produced is also minimum; Magnetic Sensor 104 and magnetic direction when vertical, Magnetic Sensor 104 magnetic flux change minimums, the magnitude of voltage minimum that produced, Magnetic Sensor magnetic 103 flux maximums, the magnitude of voltage maximum that is produced, same, this magnitude of voltage may be a maximum positive voltage, also may be peak suction.
Two Magnetic Sensors are because the earth magnetic field produces the correspondent voltage value, the magnetic direction computing module is extrapolated the magnetic direction data according to the magnitude of voltage of two Magnetic Sensors that collect, it also is the angle of Magnetic Sensor 104 and magnetic direction, be magnetic declination, and this magnetic declination is sent to the magnetic direction display module.The magnetic direction display module then calculates the angle of magnetic direction and screen vertical direction according to the angle between this magnetic declination and Magnetic Sensor 104 and the screen vertical direction, it is direction deflection angle, be reference system with the screen vertical direction afterwards, in screen, show magnetic direction according to this direction deflection angle.
For simplicity, during the direction of two Magnetic Sensors, it is vertical with the screen vertical direction of handheld device that Magnetic Sensor 103 can be set in present embodiment is set, the screen vertical direction level of Magnetic Sensor 104 and handheld device.Like this, the magnetic direction display module is when showing magnetic direction by pointer, just no longer need to adjust magnetic declination to have obtained corresponding direction deflection angle according to the angle between Magnetic Sensor and the screen vertical direction, the magnetic declination that the magnetic direction computing module obtains is direction deflection angle.
The magnetic direction display module is when showing magnetic direction according to direction deflection angle, can come direction indication by direction signs, described direction signs can comprise due east, Zheng Xi, due south, positive northern four direction sign, and a circle that can show in screen fully is set, this four direction is presented on the circumference with identifying vertical symmetry.These direction signs can also comprise arm for direction indicator, the stiff end of this arm for direction indicator is arranged on the center of circle, and makes the angle of arm for direction indicator and screen vertical direction equal direction deflection angle, show magnetic direction, i.e. direct north by this arm for direction indicator in screen.
By above-mentioned setting, can pass through the handheld device display direction.When handheld device caused drift angle between screen vertical direction and the magnetic direction to change because of rotated position, handheld device can show magnetic direction again by the direction signs in the rotating screen.
Digital compass module can realize that the magnetic direction display module then can be integrated in the middle of the application program of a portable terminal, to realize purpose of the present invention easily by a special electronic device.This electronic device is called the compass device, and this compass device need provide the driving interface of standard to handheld device.Handheld device starts the compass device by this driving interface, and obtains the magnetic direction data, then sends these magnetic direction data to corresponding application by the application programming interface function, by the application program display direction.
The above only is the present invention program's preferred embodiment, not in order to limit protection scope of the present invention.
