When the target antenna is selected from the main body antenna and the wearing portion antenna, the GPS signal receiving antenna used at the present time can be excluded.
Referring to fig. 4, fig. 4 is a schematic view of a bottom 132 of a main body portion 130 of a wearable electronic device 100 according to an embodiment of the present disclosure. A bottom cover center point 1320 exists in the bottom 132, the direction of gravity is taken as a reference direction, the reference plane 200 passes through the bottom cover center point 1320, the reference plane 200 is perpendicular to the direction of gravity, the space where the wearable electronic device 100 is located is divided into an upper portion and a lower portion by the reference plane 200, one side of the reference plane facing the direction of gravity is a lower plane, and one example of the reference plane facing away from the direction of gravity is an upper plane.

At this time, the antenna not used for receiving the GPS signal may transceive the WiFi signal or the 5G signal according to the strength of the WiFi signal or the 5G signal.
In an embodiment, the wearable electronic device 100 can detect the direction of the acceleration, and since the angles between the first antenna 110, the second antenna 120, the third antenna 134, and the fourth antenna 135 and the direction of the acceleration are different, the strength of the received GPS signal is also different, and at this time, the antenna with the smallest angle with the direction of the acceleration among the antennas can be used as the GPS signal receiving antenna.

To sum up, the wearing part that provides in the embodiment of the application includes main part and wearing part, wearing part is connected with the main part, wearing part is used for being fixed in external object with wearing formula electronic equipment, at least two main part antennas, the interval sets up on the main part, at least two main part antennas are used for receiving the GPS signal, at least two wearing part antennas, the interval sets up on wearing part, at least two wearing part antennas are used for receiving the GPS signal, a processor, with at least two main part antennas, at least two wearing part antenna electricity are connected, the processor is used for following the main part antenna according to at least one in posture and the acceleration of wearing formula electronic equipment, determine the target antenna in the wearing part antenna, and receive the GPS signal through the target antenna.
Referring to fig. 5, fig. 5 is a first flowchart of an antenna switching method according to an embodiment of the present disclosure. The antenna switching method can actively switch the GPS antenna in the electronic equipment, so that the electronic equipment is more accurately positioned.
In step 110, at least one of a posture and an acceleration of the wearable electronic device is obtained.
It can be understood that, when the wearable electronic device is carried, the direction of the wearable electronic device is oriented in various directions due to the movement of the human body, and various postures and various motion states are generated.
The posture of the wearable electronic equipment can be acquired through the posture sensor, the gravity direction of the wearable electronic equipment is acquired through the gravity sensor, and the acceleration of the wearable electronic equipment is acquired through the acceleration sensor.
For example, the direction of gravity may be obtained by a gravity sensor inside the electronic device, and the orientation of the electronic device may be resolved by establishing a three-dimensional coordinate system with the direction of gravity as a reference direction and a bottom center point of a main body of the electronic device as an origin.
Specifically, if the orientation of the screen on the electronic device main body part is consistent with the gravity direction, it can be determined that the electronic device is oriented underground at the moment, and if the orientation of the screen has an included angle with the gravity direction, which spatial region in the three-dimensional coordinate system the orientation is in is determined, it can be determined that the orientation of the electronic device is oriented at the moment.
For another example, an acceleration sensor may be installed inside the electronic device, and the direction of the acceleration and the magnitude of the acceleration may be obtained by detecting the acceleration by the acceleration sensor. The approximate movement direction of the electronic equipment can be obtained according to the direction of the acceleration, and the movement speed of the electronic equipment at the future moment can be estimated according to the magnitude of the acceleration value and the current movement speed of the electronic equipment.
After the acceleration of the electronic device is obtained, the motion state of the electronic device at the current moment can be obtained.
It should be noted that at least one of the posture and the acceleration of the wearable electronic device may be acquired.
In step 120, a current receiving antenna that receives the GPS signal is acquired from the main body antenna and the wearing portion antenna at the current time.
When the electronic equipment is in different postures or in different motion states, the GPS signal receiving antenna used by the electronic equipment is different.
When the orientation and the motion state of the electronic device change, the corresponding GPS signal also changes due to the change of the orientation of the GPS antenna, for example, when the GPS antenna faces a satellite, the received GPS signal strength is strongest, and when the GPS antenna faces underground, the received GPS signal strength of the GPS antenna is relatively weaker.
At this time, a current receiving antenna for receiving the GPS signal is acquired from the main body antenna and the wearing portion antenna of the wearable electronic device at the current time.
In step 130, the GPS signal strength corresponding to the current receiving antenna is obtained.
In step 140, it is determined whether the GPS signal strength at the current time reaches a preset strength value.
In the intensity of the electronic equipment for receiving the GPS signal, the intensity of the GPS signal can be set to be a preset intensity value, when the intensity of the GPS signal is smaller than the preset intensity value, the electronic equipment cannot be accurately positioned, and when the intensity of the GPS signal is larger than the preset intensity value, the electronic equipment can be normally positioned.
At the current moment, by detecting the orientation and the motion state of the electronic device, determining the GPS signal strength value at the current moment, and determining whether the GPS signal strength value at the current moment is greater than a preset strength value, if the GPS signal strength value at the current moment is not greater than the preset strength value, step 150 is performed, and if the GPS signal strength value at the current moment is greater than the preset strength value, step 170 is performed.
In step 150, a target antenna is determined from antennas other than the current receiving antenna among the main body portion antenna and the wearing portion antenna, based on at least one of the attitude and the acceleration.
It is understood that the determination of the target antenna among the antennas other than the current receiving antenna in the main body portion antenna or the wearing portion antenna may be determined according to at least one of the two characteristics of the attitude and the acceleration of the electronic device. That is, in the case of the posture or acceleration of the electronic device at the current time, the antenna currently receiving the GPS signal is not suitable because the GPS signal reception is weak, and it is necessary to select a target antenna from the main body antenna and the wearing portion antenna to receive the GPS signal.
Please refer to fig. 6, fig. 6 is a second flowchart of the antenna switching method according to the embodiment of the present application. Fig. 6 illustrates a method for acquiring a target antenna according to the orientation of the bottom cover of the electronic device and the gravity direction.
In step 1511, the orientation of the bottom cover is acquired by the attitude sensor.
In one embodiment, the orientation of the bottom cover can be obtained through the attitude sensor, the orientation of the bottom cover can be towards a plurality of directions, and the gravity direction can also be obtained according to the gravity sensor.
In step 1512, a reference plane perpendicular to the gravity direction is obtained, where the reference plane passes through a center point of the bottom cover, the reference plane facing the gravity direction side is a lower plane, and the reference plane facing away from the gravity direction side is an upper plane.
At this time, a center point of a bottom cover of the electronic device is used as a reference point, the gravity direction is used as a reference direction, a reference plane is generated, the reference plane is perpendicular to the gravity direction, the reference plane facing the gravity direction is a lower plane, and the reference plane facing away from the gravity direction is an upper plane.
And according to the orientation of the bottom cover and the reference plane, determining the antenna positioned on the upper plane as the target antenna from the main body part antenna and the wearing part antenna.
In step 1513, the antenna located on the upper plane is determined as the target antenna from the main body portion antenna and the wearing portion antenna based on the orientation of the bottom cover and the reference plane.
The main body part antenna comprises a third antenna and a fourth antenna, and the wearing part antenna comprises a first antenna and a second antenna. The target antenna can be selected from the first antenna, the second antenna, the third antenna and the fourth antenna to be a GPS signal receiving antenna.
For example, the antenna in the upper plane is switched to a GPS signal receiving antenna for receiving a GPS signal at a position where the antenna is oriented toward a satellite. For example, if the screen of the smart watch is facing downward and the third antenna and the fourth antenna on the middle frame are facing underground, the GPS signals received by the third antenna and the fourth antenna are weak. The first antenna and/or the second antenna on the upper plane can be switched to be a GPS signal receiving antenna.
In addition, please refer to fig. 7, fig. 7 is a third flowchart of an antenna switching method according to an embodiment of the present application. Fig. 7 illustrates selection of a target antenna by acceleration of the wearable electronic device.
In step 1521, an acceleration of the wearable electronic device is obtained by the acceleration sensor.
In step 1522, an angle between the acceleration direction and the main body antenna and the wearing portion antenna is obtained.
In an embodiment, by obtaining the direction of the acceleration, the first antenna, the second antenna, the third antenna, and the fourth antenna have different angles with the direction of the acceleration, and because the four antennas are oriented differently, the four antennas have different angles with the direction of the acceleration.
In step 1523, the antenna with the smallest angle with the acceleration direction is determined as the target antenna among the main body part antenna and the wearing part antenna
It can be understood that the smaller the included angle between the GPS signal receiving antenna and the acceleration direction is, the more accurate the acquired GPS signal is, and at this time, the GPS signal receiving antenna may be switched according to the included angles between the first antenna, the second antenna, the third antenna, and the fourth antenna and the acceleration direction.
It should be noted that the target antenna may also be obtained through the attitude and the acceleration of the electronic device, for example, the antenna that has the smallest angle with the acceleration direction and is located on the upper plane is the target antenna.
In this way, in step 160, the processor may determine, as the target antenna, the antenna having the smallest angle with the acceleration direction, from among the main body portion antenna and the wearing portion antenna.
In step 170, if it is determined that the GPS signal strength at the current time is greater than the preset strength value, the GPS signal receiving antenna does not need to be switched.
In one embodiment, if the GPS signal strength at the current time is greater than the predetermined strength value, the antenna that is not used to receive the GPS signal is selected to receive and transmit the 5G or WiFi signal.
There are a plurality of frequency band switching points in first antenna, second antenna, third antenna and fourth antenna, can change the signal that the antenna was received and dispatched according to the difference of the position that the frequency band switching point set up on the antenna, for example, can realize the receiving and dispatching of wiFi signal, LTE signal and 5G signal according to the change of frequency band switching point.
To sum up, in this application embodiment, through obtaining in posture and the acceleration of wearable electronic equipment at least one, obtain the current receiving antenna of receiving the GPS signal in current moment main part antenna, the wearing portion antenna, obtain the GPS signal intensity that current receiving antenna corresponds, judge whether the GPS signal intensity of current moment is greater than and predetermine the intensity value, according to the posture and at least one in the acceleration is followed the main part antenna determine the target antenna in the wearing portion antenna, control the target antenna receives the GPS signal.
Therefore, when the posture and the motion state of the electronic equipment are changed, the GPS signal receiving antenna is actively switched to achieve the effect of accurate positioning.
