Embodiment
Hereinafter, the preferred embodiments of the present invention are described in detail with reference to accompanying drawing.Note, in the present description and drawings, there is substantially the same step and represent with the identical Reference numeral of element, and will be omitted the repetition of explanation of these steps and element.
Below, the method for the signal transacting of embodiments of the invention is described with reference to Fig. 1.Fig. 1 depicts the flow chart of the signal processing method 100 according to the embodiment of the present invention.Signal processing method 100 can be applicable to the first electronic equipment.In an embodiment according to the present invention, the concrete form of the first electronic equipment can include but not limited to Intelligent bracelet, intelligent glasses, smart mobile phone etc., and the first electronic equipment comprises the first antenna and the second antenna.
According to one embodiment of present invention, the first antenna and the second antenna are not identical.First antenna is the antenna that transmitting power is stronger, and the second antenna is the more weak antenna of transmitting power.For the difference of two antennas in transmitting power, there is unlike signal gain amplifier realize by two antennas are designed in the design process.
Fig. 2 is that bluetooth double antenna is to RSSI value effect tendency figure.When an identical signal is input to the first antenna and the second antenna respectively, the signal power exported from the first antenna is stronger, the signal power exported from the second antenna is more weak, with reference to shown in Fig. 2, the RSSI value (received signal strength indicator) detected by receiving equipment is known with distance change experiment, the RSSI value of the second antenna that power output is more weak has compared significant change in 0cm with 10-20cm interval, 10-20cm is interval simultaneously compares with 30-40cm interval and has significant change, and the RSSI value of stronger the first antenna of power output is all not obvious in whole 0-50cm interval change, thus antenna handoff technique can be utilized, closely time, (as 0-50cm) is switched to the more weak antenna of power output (performance is weak) from the antenna (performance is strong) that power output is stronger and realizes distance detection more accurately.
Can be the antenna in electronic product with proper communication function at the first antenna, the second antenna is specifically designed to the antenna of transmitting power compared with weak signal.Particularly, this signal processing method 100 comprises following steps shown in Fig. 1.
As shown in Figure 1, in step S101, send the first signal by first day alignment second electronic equipment of the first electronic equipment.According to an example of the present invention, the first antenna can be the antenna that the first electronic equipment and other equipment carry out normal communication.First signal of this first antenna transmission can comprise the uninterrupted signal of continuation or cyclic pulse signal, such as bluetooth, WIFI etc.Meanwhile, the signal strength signal intensity of the first signal of transmitting is constant, in order to avoid in subsequent step when carrying out condition judgment or range measurement according to the signal strength signal intensity of reception first signal, produces unnecessary erroneous judgement or error because the intensity of the first signal launched changes.
In step s 102, receive the first switching signal from the second electronic equipment, wherein the first switching signal indicates the second electronic equipment according to the signal strength signal intensity first predetermined condition of the first signal received.According to embodiments of the invention, when the second electronic equipment receives the first signal of the first electronic equipment transmitting, signal strength signal intensity (RSSI) according to the first signal received is confirmed whether first predetermined condition, when confirming first predetermined condition, second electronic equipment outwards sends the first switching signal, and the receiving element of the first electronic equipment receives the first switching signal.
For the first predetermined condition, can arrange and comprise the various forms of conditions relevant to signal strength signal intensity.According to an example of the present invention, the first predetermined condition refers to that the second electronic equipment calculates according to the signal strength signal intensity of described first signal received the distance between itself and described first electronic equipment obtained and is less than the first preset distance.When the spacing of the first electronic equipment and the second electronic equipment changes, therefore the signal strength signal intensity of the first signal that the second electronic equipment receives also changes, therefore distance becomes corresponding relation with signal strength signal intensity, can according to the signal strength signal intensity judgement distance between the two received with this.First preset distance is included in the power of the second antenna transmission of the first electronic equipment compared with in the signal cover of weak signal, and what ensure to be switched to that the second antenna transmission power can receive compared with the second electronic equipment during weak signal when the first electronic equipment with this arrives.
According to embodiments of the invention, first switching signal is control signal, perform handover operation for controlling the first electronic equipment, therefore the signal strength signal intensity of the first switching signal at least should cover the first electronic equipment position, and what can receive to make the first electronic equipment arrives.
Then, in step s 103, the first electronic equipment according to the first switching signal received, from by the first antenna transmission first signal switching to by the second antenna transmission secondary signal.According to embodiments of the invention, wherein, when the first electronic equipment only receives the first switching signal, just control transmitter unit from passing through the first antenna transmission first signal switching to passing through the second antenna transmission secondary signal by control unit.According to an example of the present invention, first antenna and the second antenna are connected to the same transmitter unit of the first electronic equipment, and described first electronic equipment controls described first antenna respectively by this transmitter unit and described second antenna outwards launches described first signal and described secondary signal.Such as, the transmitter unit of the first electronic equipment passes through the first higher signal of the first antenna transmitting power, when receiving the first switching signal, the control unit of the first electronic equipment controls transmitter unit to be stopped, by the first higher signal of the first antenna transmitting power, transferring by the lower secondary signal of the second antenna transmission power.Switched respectively by a transmitter unit and control the structure of two antenna transmissions, make the first electronic equipment without the need to increasing extra emission controlling unit module, provide cost savings, reduce design difficulty, especially all Bluetooth technology is supported for existing portable set major part, Bluetooth transmission unit can retain and not need to add extra transmitter module, highly versatile.
Alternatively, according to another example of the present invention, first antenna and the second antenna can be connected to the first transmitter unit and second transmitter unit of the first electronic equipment, wherein, first transmitter unit controls the first higher signal of the first antenna transmitting power, and the second transmitter unit controls the lower secondary signal of the second antenna transmission power.Such as, when receiving the first switching signal, the control unit of the first electronic equipment controls the first transmitter unit to be stopped by the first higher signal of the first antenna transmitting power, then startup second transmitter unit passes through the lower secondary signal of the second antenna transmission power.
According to embodiments of the invention, for the example that the first antenna and the second antenna are controlled by the same transmitter unit of the first electronic equipment, transmitter unit can by the signal of the first antenna with the identical type of the second antenna transmission, such as Bluetooth signal, or, transmitter unit can respectively by the first antenna and the dissimilar signal of the second antenna transmission, such as the first antenna transmission WIFI signal, the second antenna transmission Bluetooth signal.And for the example that the first antenna and the second antenna are controlled separately by the different transmitter units of the first electronic equipment respectively, first transmitter unit can as the transmitter module of identical type respectively by the signal of the first antenna with the identical type of the second antenna transmission with the second transmitter unit, such as Bluetooth signal, or, first transmitter unit and the second transmitter unit can as dissimilar transmitter modules, thus respectively by the first antenna and the dissimilar signal of the second antenna transmission, such as the first antenna transmission WIFI signal, the second antenna transmission Bluetooth signal.
In step S104, secondary signal is sent by second day alignment second electronic equipment, distance between itself and the first electronic equipment can be calculated according to the signal strength signal intensity of the secondary signal received to make the second electronic equipment, wherein, the second antenna is the more weak antenna of transmitting power relative to the first antenna.When designing, the gain amplifier of the second antenna is less than the gain amplifier of the first antenna.As described above, because the second antenna transmission power is more weak, the intensity (such as 10cm-50cm) in short range of the secondary signal that it is launched is more responsive with distance change, namely received signal strength indicator (RSSI) is more responsive, the precision of the distance therefore calculated with the signal strength signal intensity of described secondary signal is higher than the precision of the distance calculated with the signal strength signal intensity of described first signal, and can be used for the distance of perception close-in target object changes.
According to embodiments of the invention, within second day, alignment second electronic equipment sends secondary signal, because the secondary signal of launching is more weak compared to the first signal power, when the second electronic equipment receives secondary signal, now the second electronic equipment should be in the short range close to the first electronic equipment.Meanwhile, it is more responsive that the change due to the intensity distance of secondary signal changes, and the second electronic equipment can calculate the more accurate distance change of distance the first electronic equipment according to the intensity of the secondary signal received.
As above, according to the signal processing method of the embodiment of the present invention, by double antenna switching controls, both can perception remote equipment, again can perception near field communication devices, namely ensure that the closely perception can carrying out target device in this way, also can not have influence on the remote perception of target device simultaneously because of transmitting power not, overcome the various shortcomings of current distance measuring method.
Below, the signal processing method of another embodiment of the present invention is described with reference to Fig. 3.Fig. 3 depicts the flow chart of signal processing method 300 according to an embodiment of the invention.
Similar with the method shown in Fig. 1, in step S301, send the first signal by first day alignment second electronic equipment of the first electronic equipment.In step s 302, receive the first switching signal from the second electronic equipment, wherein the first switching signal indicates the second electronic equipment according to the signal strength signal intensity first predetermined condition of the first signal received.As mentioned above, the first predetermined condition can arrange and comprise the various forms of conditions relevant to signal strength signal intensity.According to embodiments of the invention, the first predetermined condition refers to that the second electronic equipment calculates according to the signal strength signal intensity of described first signal received the distance between itself and described first electronic equipment obtained and is less than the first preset distance.In step S303, the first electronic equipment according to the first switching signal received, from by the first antenna transmission first signal switching to by the second antenna transmission secondary signal.And in step s 304, send secondary signal by second day alignment second electronic equipment, distance between itself and the first electronic equipment can be calculated according to the signal strength signal intensity of the secondary signal received to make the second electronic equipment.
Signal processing method 300 also can be included in step S304 after startup first electronic equipment in the step S305 of the default application corresponding with enabling signal or default unit.Specifically as shown in Figure 3, in step S305, enabling signal is received from the second electronic equipment, wherein enabling signal indicates the second electronic equipment to be less than the second preset distance according to the signal strength signal intensity of the secondary signal the received distance calculated between itself and the first electronic equipment, starts default application corresponding with enabling signal in the first electronic equipment or default unit.
According to embodiments of the invention, second electronic equipment calculates the distance between itself and the first electronic equipment according to the signal strength signal intensity of the secondary signal of launching in step s 304 received, when this distance calculated is less than the second predeterminable range, second electronic equipment outwards sends enabling signal, wherein, second preset distance weighs according to the signal strength signal intensity of the secondary signal of the second antenna transmission the condition whether distance calculated meets preset distance, and the first predeterminable range mentioned before weighs according to the signal strength signal intensity of the first signal of the first antenna transmission the condition whether distance calculated meets preset distance, the intensity of the secondary signal of the second antenna transmission compared to the intensity of the first signal of the first antenna transmission change when the change with distance more responsive, be more conducive to the distance change of perception close-in target equipment, therefore the setting of the second predeterminable range should be less than the first predeterminable range.Simultaneously, enabling signal goes to perform for making the first electronic equipment start the triggering signal preset application, operation or control, when the first electronic equipment receives enabling signal, the control unit in the first electronic equipment starts to control corresponding units in the first electronic equipment and performs the operation preset.And, first electronic equipment can send request signal or control enabling signal according to the needs of operation or application to the second electronic equipment when performing predetermined registration operation, makes the second electronic equipment coordinate the first electronic equipment to perform relevant operation or application according to the request signal received or control enabling signal.
For current design of electronic products, power problems is a problem that must consider all the time, and the Portable movable electronic product for increasingly extensive use then seems and is even more important.Therefore, two kinds of situations may be had occur after step S301, a kind of situation being the first electronic equipment mentioned as step S302 and receiving the first switching signal from the second electronic equipment, another kind of then be the first switching signal that the first electronic equipment never receives from the second electronic equipment, namely the second electronic equipment is never to the situation of the first electronic equipment response.
For above-mentioned the second situation, may be because this time period does not have the second electronic equipment around the first electronic equipment, or the second electronic equipment distance the first electronic equipment too far cannot receive the first signal.The power needed compared to the secondary signal of the second antenna transmission due to the first signal of the first antenna transmission is higher, in order to prevent the first electronic equipment because the too much power consumption of undying transmitting first signal losses, therefore also having after step S301 according to another embodiment of the present invention and judging whether the time span of transmitting first signal exceedes the step S306 of scheduled duration and perform the step S307 of control first signal transmitting.
Particularly, in step S306, first electronic equipment should arrange a scheduled time length, and from launch the first signal time just calculate transmitting first signal time span before receiving the first switching signal, whether exceed the scheduled time length of setting, when exceeding scheduled time length, in step S307, first electronic equipment controls described transmitter unit by control unit, it is made to stop generating and sending the first signal, or, extend the generation of the first signal and the cycle of transmission, the effect of saving first powder consumption of electronic equipment is reached with this, wherein, scheduled time length can carry out choose reasonable according to actual conditions such as battery capacities.
Distance due to the first electronic equipment and the second electronic equipment belongs to dynamic change, likely keeps close, also likely unexpected away from.Therefore, when first predetermined condition makes the first electronic equipment be switched to by described second antenna transmission secondary signal, the situation when the first electronic equipment and the second electronic equipment distance between the two not first predetermined condition also can be considered.
Therefore, according to another embodiment of the present invention, method described in Fig. 3 also can comprise and receives the second switching signal from the second electronic equipment, wherein the second switching signal indicates the second electronic equipment according to the signal strength signal intensity of the secondary signal received not first predetermined condition, according to described second switching signal received, switch back through the first antenna transmission first signal from by the second antenna transmission secondary signal.According to embodiments of the invention, first electronic equipment is by described second antenna transmission secondary signal, second electronic equipment calculates the distance between itself and the first electronic equipment according to the signal strength signal intensity of the secondary signal received, when the distance calculated due to two electronic equipments away from not first predetermined condition time, second electronic equipment sends the second switching signal, first electronic equipment is switched back through the first antenna transmission first signal from by the second antenna transmission secondary signal, ensure that the second electronic equipment is away from the signal that still can receive the first electronic equipment during the first electronic equipment and send with this, and continue to measure distance between the two according to signal strength signal intensity.According to example of the present invention, the first predetermined condition can comprise the first preset distance.
In addition, when there is multiple second electronic equipment around the first electronic equipment, in order to ensure the first electronic equipment not by the signal disturbing of other multiple second electronic equipments, avoid signal response chaotic, according to embodiments of the invention, the first switching signal that each second electronic equipment sends and the second switching signal contain the identification information of this second electronic equipment, when the first electronic equipment first time received the first switching signal, by the identification information sending the second electronic equipment of this first switching signal that cell stores first switching signal contains, first electronic equipment is when receiving the second switching signal afterwards, first confirm that whether the identification information that the second switching signal contains is corresponding with the identification information that the first switching signal stored contains, when the identification information that described second switching signal received contains is corresponding with the identification information that described first switching signal of storage contains, switch back through described first antenna transmission first signal from by described second antenna transmission secondary signal, ensure that the first electronic equipment processes the response signal of same second electronic equipment all the time with this, avoid response or misoperation by mistake.
At this, according to the description of the signal processing method 300 of the embodiment of the present invention, can solve without energy consumption problem during response by arranging scheduled time length, and mistake response and the misoperation problem of multiple device signal can be solved by storing comparison identification information, simultaneously, starting the related application in two electronic equipments according to the distance exam of secondary signal intensity, is the further perfect of signal processing method 100 shown in Fig. 1, further overcomes the various shortcomings of current distance measuring method.
