All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The terms first, second and the like in the description and in the claims and in the above-described figures are used for distinguishing between different objects and not necessarily for describing a sequential or chronological order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
For a better understanding of aspects of embodiments of the present application, related terms and concepts that may be related to embodiments of the present application are described below.
Ultra Wide Band (UWB) communication technology is a wireless carrier communication technology using a frequency bandwidth of 1GHz or more. The method does not adopt a sine carrier, but utilizes nanosecond non-sine wave narrow pulse to transmit data, and the impulse has high positioning precision. With UWB technology, it is easy to integrate positioning and communication, which is difficult for conventional radios to do. UWB technology has very strong penetration capability and can be used for accurate positioning indoors and underground, while the global positioning system (Global Positioning System, GPS) can only work within the visible range of GPS positioning satellites. Unlike GPS, which provides absolute geographic position, ultra wideband radio positioners can give relative positions with positioning accuracy on the order of centimeters.
The UWB ranging principle is the same as global navigation satellite system (Global Navigation Satellite System, GNSS) outdoor positioning and Bluetooth indoor positioning, and the Time of Flight of a radio signal is used for measuring and calculating the distance.
Phase-Difference-of-Arrival (PDOA) ranging algorithms, while the use of the PDOA scheme implies that a dual-antenna or multi-antenna system is required. If the object has more than two antennas, the angle and distance between the object and the object can be judged according to the difference value of the phases of the same signals received by the two antennas. In the embodiment of the application, a dual-antenna architecture is adopted for PDOA ranging.
A time difference of arrival (Time Difference of Arrival, TDOA) ranging algorithm can determine the location of a mobile station by detecting the absolute time difference of arrival of a signal at two base stations, rather than the time of flight of the arrival.
Angle-of-Arrival (AOA) ranging algorithm, a signal Angle-of-Arrival based positioning algorithm is a typical ranging-based positioning algorithm, which senses the direction of Arrival of the transmitting node signal by some hardware device, calculates the relative orientation or Angle between the receiving node and the anchor node, and then calculates the position of the unknown node using triangulation or other means.
The existing ultra-wideband communication device is often limited by the influence of cost or using portability, is inconvenient to use and has poor user experience.
In order to solve the above-mentioned problems, the antenna selection device described in the embodiments of the present application may be applied to the above-mentioned ultra-wideband communication method, and will not be described herein. The antenna selection device, the method and the wearable equipment provided by the embodiment of the application mainly identify the current wearing scene to reasonably select the antenna before ultra-wideband communication is performed so as to improve the communication quality, and the wearable equipment is small in size and convenient to carry, so that the cost is reduced and the user experience is greatly improved.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an antenna selection device 100 according to an embodiment of the present application, which includes a sensor module 110, a processor module 120, an antenna module 130, and a switch module 140, wherein the sensor module 110 includes a plurality of first sensor units 111, the antenna module 130 includes a plurality of antennas, the processor module 120 may be a micro control unit (Microcontroller Unit, MCU), and the switch module 140 may include a plurality of switches. The number of switches in the switch module 140 is the same as the number of antennas in the antenna module 130, and the switches are in one-to-one correspondence with the antennas, that is, when one switch is closed, the corresponding antenna can transmit a wireless signal, and when one switch is opened, the corresponding antenna cannot transmit a wireless signal.
Wherein the sensor module 110 is connected to the processor module 120, the processor module 120 is connected to the switch module 140, and the switch module 140 is connected to the antenna module 130. It should be noted that each switch in the switch module 140 is connected to each antenna in the antenna module 130 one by one.
In one possible embodiment, the plurality of first sensor units 111 in the sensor module 110 may be a plurality of proximity sensors, each proximity sensor including an infrared emitting end and an infrared receiving end, the infrared emitting end being configured to emit infrared rays outwards, the infrared receiving end being configured to receive reflected infrared rays, and the distance between the proximity sensor and the target object may be determined by a time stamp of the infrared emitting end emitting infrared rays outwards and a time stamp of the infrared receiving end receiving reflected infrared rays, the target object being an obstacle in a signal coverage space of the each first sensor unit 111, it may be understood that the first sensor units 111 may be configured to collect distance information indicating a distance between each first sensor unit 111 and the target object. For example, the first sensor unit 111 disposed in front of the antenna selection device 100 may collect a distance between itself and a front target object of 50 cm, and the first sensor unit 111 disposed on the left side of the antenna selection device 100 may collect a distance between itself and a left target object of 10 cm, and so on, which will not be described herein.
Further, the processor module 120 may generate a switch selection signal according to the distance information collected by the first sensor unit 111, where the switch selection signal may include a first switch selection signal, and is responsible for turning on the first switch unit in the switch module 140, if the switch module includes a second switch unit, a third switch unit, etc., the processor module 120 may also generate a second switch selection signal or a third switch selection signal according to the distance information, and so on, which are not listed herein. It should be noted that, in the above-mentioned switch module 140, all the switch units are in an off state in the initial state, and only turned on when receiving the corresponding switch selection signal, for example, the first switch selection signal may turn on the first switch unit, the second switch selection signal may turn on the second switch unit, the third switch selection signal may turn on the third switch unit, and so on, which are not listed herein.
Specifically, in general, the farther the distance between the proximity sensor and the target object is, the less likely the signal transmission in the corresponding area of the proximity sensor is blocked, so that there is a corresponding relationship between each proximity sensor and each antenna in the antenna module 130, for example, the first proximity sensor is responsible for collecting the distance information of the first area, the second proximity sensor is responsible for collecting the distance information of the second area, and the third proximity sensor is responsible for collecting the distance information of the third area, where the first antenna unit is located in the first area, the second antenna unit is located in the second area, and the third antenna unit is located in the third area. When the processor module 120 determines that the distance information of the first area is farthest, the obstacle of the first area is farther than the obstacle of the second area and the third area, it may be determined that the communication efficiency of the first antenna unit located in the first area is higher than the communication efficiency of the second antenna unit located in the second area and the communication efficiency of the third antenna unit located in the third area, and a first switch selection signal may be generated.
Further, the switch module 140 may receive a switch selection signal from the processor module 120, determine a switch unit to be turned on according to the switch selection signal, and turn on the first switch unit to start the first antenna unit when the switch selection signal is a first switch selection signal; when the switch selection signal is a second switch selection signal, the second switch unit can be conducted to start the second antenna unit; when the switch selection signal is a third switch selection signal, the third switch unit can be conducted to start the third antenna unit; any of the antenna elements of the antenna module 130 may transmit wireless signals after being activated.

In the following description of a wearable device according to an embodiment of the present application with reference to fig. 3, fig. 3 is a schematic structural diagram of a wearable device provided by the embodiment of the present application, the wearable device 300 may include all or part of the antenna selection apparatuses described in fig. 1 and fig. 2, the wearable device 300 may be a ring, a ring structure is provided, the size and materials of the wearable device 300 are not particularly limited, as shown in the drawing, three first sensor units provided on the wearable device 300 divide the ring structure into three curves with the same length, the left curve is an area where the first antenna unit is located, the right curve is an area where the second antenna unit is located, and the lower curve is an area where the third antenna unit is located.
For example, when the first proximity sensor IR/PD1 is worn between the index finger and the middle finger, the infrared ray emitted by the IR1 will be immediately reflected back to the PD1 by the finger, so that it can be determined that the distance between the first proximity sensor and the obstacle is close to 0, the region where the first antenna unit is located is blocked by the finger, and the ultra-wideband communication quality of the first antenna unit is poor; further, when the user wears the wearable device 300, the user often has a virtual hand holding state, so that when the distance information acquired by the second proximity sensor IR/PD2 is closer than the distance information acquired by the third proximity sensor IR/PD3, it can be determined that the area where the second antenna unit corresponding to the second proximity sensor is located faces towards the palm, and the third antenna unit is the optimal communication antenna; similarly, when the distance information acquired by the second proximity sensor IR/PD2 is far away from the distance information acquired by the third proximity sensor IR/PD3, the second antenna unit is the optimal communication antenna.
For reasons of space limitation, only the first proximity sensor IR/PD1, the second proximity sensor IR/PD2, and the third proximity sensor IR/PD3 are shown in fig. 3, and in one possible embodiment, the wearable device 300 may further include a first acceleration sensor, a second acceleration sensor, and a third acceleration sensor, where the first acceleration sensor may be disposed near the first proximity sensor, the second acceleration sensor may be disposed near the second proximity sensor, and the third acceleration sensor may be disposed near the third proximity sensor, for collecting motion information of the wearable device 300.
It should be noted that the above embodiment is only one possible structure, and does not represent a specific limitation on the wearable device in the embodiment of the present application.
It can be seen that the current wearing scene can be identified before ultra-wideband communication is carried out for reasonable antenna selection so as to improve communication quality, and the user experience can be greatly improved while the cost is reduced due to the small size and portability of the wearable device.
An antenna selection method in the embodiment of the present application is described below with reference to fig. 4, and fig. 4 is a schematic flow chart of the antenna selection method provided in the embodiment of the present application, which is applied to a wearable device, and specifically includes the following steps:
step 401, determining a wearing state of the wearable device when worn on a hand of a user.
The wearable device comprises a wearable device, a sensor module and a distance sensor, wherein the wearable device can determine the wearing state of the wearable device when worn on the hand of a user, the sensor module comprises at least three proximity sensors, each proximity sensor comprises an infrared transmitting end and an infrared receiving end, time difference data between an infrared transmitting time stamp of the infrared transmitting end and an infrared receiving time stamp of the infrared receiving end of each proximity sensor can be obtained, and a first position relation between an area corresponding to each proximity sensor and the hand of the user is determined according to the time difference data, wherein the first position relation can represent distance information between each proximity sensor and the hand of the user.
Therefore, through determining the wearing state of the wearable device when the wearable device is worn on the hand of the user, the obstacle of signal transmission in which direction exists can be detected, and the communication quality is improved.
And step 402, determining the communication priority of the antenna module according to the wearing state.
The method comprises the steps that all antennas in the antenna module work according to the sequence of the communication priority, specifically, the signal shielding level of the area corresponding to each first sensor unit can be determined according to the first position relation, and the communication priority of the antenna module is determined according to the sequence of the signal shielding level and the antenna setting area of the antenna module on the wearable equipment. Specifically, the lower the signal shielding level of the area corresponding to the first sensor unit is, the higher the communication priority of the corresponding antenna is.
Therefore, the communication priority of the antenna module is determined according to the wearing state, and an appropriate antenna can be automatically selected for ultra-wideband communication, so that the communication accuracy and efficiency are improved.
And step 403, controlling the opening and closing states of the switch module according to the communication priority.
Each switch of the switch module corresponds to each antenna of the antenna module one by one, a switch selection signal can be generated through the processor, the switch corresponding to the antenna with the highest communication priority is selected to be closed, and the other switches are opened. Specifically, the switch of the switch module corresponding to the antenna in the antenna module with the highest communication priority is controlled to be closed, and the switch of the switch module corresponding to the antenna in the antenna module with the non-highest communication priority is controlled to be opened.
Therefore, the switch module is controlled to be opened or closed according to the communication priority, so that the appropriate antenna can be selected for communication according to the wearing state, and the communication quality is improved.
Step 404, transmitting an ultra wideband signal to a target device.
And the ultra-wideband signal is transmitted through the antenna with the highest priority in the antenna module.
In one possible embodiment, a first transmission instruction may be sent to the ultra-wideband module, where the first transmission instruction is used to control the ultra-wideband module to transmit a first ultra-wideband signal to the target device.
In one possible embodiment, the sensor module further includes an acceleration sensor, after determining the first positional relationship between the area corresponding to each proximity sensor and the hand of the user according to the time difference data, acceleration data of the wearable device when the wearable device is worn on the hand of the user may be further obtained through the acceleration sensor, and a spatial motion track of the wearable device is determined according to the acceleration data. Further, a second transmission instruction may be sent to the ultra-wideband module, where the second transmission instruction is used to control the ultra-wideband module to transmit a second ultra-wideband signal to the target device, and the second ultra-wideband signal carries information of the spatial motion track. For active interaction of the wearable device with the target device, such as interaction of a waving instruction, etc.
It can be understood that the wearable device may periodically transmit UWB signals, detect a wearing state of the wearable device before each transmission, determine a communication priority of an antenna according to the wearing state, further invoke an antenna with a highest priority to perform ultra-wideband communication, if ultra-wideband communication is not successful in a preset period, invoke an antenna with a second priority to perform ultra-wideband communication, if ultra-wideband communication is successful in the preset period, adjust the second priority to the highest priority, if ultra-wideband communication is not successful in the preset period, switch to an antenna with a third priority again to perform ultra-wideband communication, if ultra-wideband communication is successful in the preset period, adjust the third priority to the highest priority, and if ultra-wideband communication is not successful in the preset period, recycle again, which is not described herein.
Therefore, by the method, the current wearing scene can be identified to carry out reasonable antenna selection before ultra-wideband communication is carried out, so that the communication quality is improved, and the user experience can be greatly improved while the cost is reduced due to the small size and portability of the wearable equipment.
