Detailed Description
In order to make the technical solutions of the present application better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms "first," "second," and the like in the description and claims of the present application and in the above-described drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively 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 can be included in at least one embodiment of the application. The appearances of the phrase 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. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein may be combined with other embodiments.
In order to better understand the scheme of the embodiments of the present application, the following first introduces the related terms and concepts that may be involved in the embodiments of the present application.
An Ultra Wide Band (UWB) communication technology is a wireless carrier communication technology using a frequency bandwidth of 1GHz or more. It does not adopt sine carrier wave, but uses nanosecond non-sine wave narrow pulse to transmit data, and the impulse pulse has high positioning accuracy. With UWB technology, it is easy to integrate positioning with communication, which is difficult to do with conventional radios. UWB technology has a strong penetration capability and can perform precise Positioning indoors and underground, while the Global Positioning System (GPS) can only work within the visible range of GPS Positioning satellites. Unlike GPS, which provides an absolute geographic location, an ultra-wideband radio locator can give a relative location with a positioning accuracy of up to centimeter level.
The UWB ranging principle is the same as Global Navigation Satellite System (GNSS) outdoor positioning and bluetooth indoor positioning, and the distance is measured and calculated by using the Time of Flight of a radio signal, which is the same as the Time of Flight of the radio signal.
Phase-Difference-of-Arrival (PDOA) ranging algorithm, while the PDOA scheme implies that a dual-antenna or multi-antenna system is required. If the object has more than two antennae, the angle and the distance of the identification object from the object can be judged according to the difference value of the phases of the same signals received by the two antennae. In the embodiment of the present application, a dual-antenna architecture is adopted to perform PDOA ranging.
Time Difference of Arrival (TDOA) ranging algorithms can determine the location of a mobile station by detecting the absolute Time Difference between the Arrival of a signal at two base stations, rather than the Time of flight of the Arrival.
Angle-of-Arrival (AOA) ranging algorithm, which is a typical ranging-based positioning algorithm, senses the Arrival direction of a signal of a transmitting node through some hardware devices, calculates the relative position or Angle between a receiving node and an anchor node, and then calculates the position of an unknown node by triangulation or other methods.
The existing ultra-wideband communication device is often limited by the influence of cost or use portability, is inconvenient to use and has poor user experience.
In order to solve the above problem, the antenna selection apparatus described in the embodiment of the present application may be applied to the above ultra-wideband communication method, and is not described herein again. The antenna selection device, the antenna selection method and the wearable device provided by the embodiment of the application mainly identify the current wearing scene before ultra-wideband communication so as to perform reasonable antenna selection, so that the communication quality is improved, and the wearable device is small in size and convenient to carry, so that the user experience can be greatly improved while the cost is reduced.
Fig. 1 is a schematic structural diagram of an antenna selection apparatus 100 provided in this embodiment, and includes a sensor module 110, a processor module 120, an antenna module 130, and a switch module 140, where 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 Controller 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 correspond to the antennas one to one, that is, when one switch is turned off, the corresponding antenna can transmit wireless signals, and when one switch is turned off, the corresponding antenna cannot transmit wireless signals.

Specifically, generally speaking, the farther the proximity sensor is from the target object, the less easily the signal transmission in the area corresponding to the proximity sensor is blocked, so that each proximity sensor and each antenna in the antenna module 130 have a corresponding relationship, for example, the first proximity sensor is responsible for acquiring the distance information of the first area, the second proximity sensor is responsible for acquiring the distance information of the second area, and the third proximity sensor is responsible for acquiring the distance information of the third area, 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 the farthest, the obstacle of the first area is farther than the obstacles of the second area and the third area, and 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 at this time, and the first switch selection signal may be generated.
Further, the switch module 140 may receive a switch selection signal from the processor module 120, and determine a switch unit to be turned on according to the switch selection signal, and when the switch selection signal is a first switch selection signal, turn on the first switch unit to start the first antenna unit; when the switch selection signal is the second switch selection signal, the second switch unit can be turned on to start the second antenna unit; when the switch selection signal is the third switch selection signal, the third switch unit may be turned on to start the third antenna unit; any one of the antenna units in the antenna module 130 may transmit a wireless signal after being activated.

A wearable device in this embodiment is described below with reference to fig. 3, fig. 3 is a schematic structural diagram of a wearable device provided in this embodiment, the wearable device 300 may include all or part of the antenna selection apparatus described in fig. 1 and fig. 2, the wearable device 300 may be a ring and have a ring structure, where the size and material of the wearable device 300 are not specifically limited, as shown in the figure, three first sensor units disposed on the wearable device 300 divide the ring structure into three segments of curves with the same length, a left side curve is an area where the first antenna unit is located, a right side curve is an area where the second antenna unit is located, and a lower side curve is an area where the third antenna unit is located, and thus, when the wearable device 300 is worn on a finger of a user, the first sensor units are disposed so that it is convenient for the first sensor units to determine whether the finger is an obstacle of the wearable device 300 in a current gesture state.
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 is immediately reflected back to the PD1 by the finger, and it can be determined that the distance between the first proximity sensor and the obstacle is close to 0, the area 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 judging that the user often has a hand in a virtual holding state when wearing the wearable device 300, when the distance information acquired by the second proximity sensor IR/PD2 is shorter 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 is toward the palm of the hand, and the third antenna unit is the best communication antenna; similarly, when the distance information collected by the second proximity sensor IR/PD2 is longer than the distance information collected by the third proximity sensor IR/PD3, the second antenna unit is the best communication antenna.
For reasons of space limitation, only the first, second and third proximity sensors IR/PD1, IR/PD2, 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, the first acceleration sensor may be disposed in the vicinity of the first proximity sensor, the second acceleration sensor may be disposed in the vicinity of the second proximity sensor, and the third acceleration sensor may be disposed in the vicinity of 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 to the wearable device in the embodiment of the present application.
Therefore, the current wearing scene can be identified before ultra-wideband communication is carried out, reasonable antenna selection is carried out, the communication quality is improved, and the wearable equipment is small in size and convenient to carry, so that the user experience can be greatly improved while the cost is reduced.
Fig. 4 is a schematic flow chart of the antenna selection method provided in the embodiment of the present application, and the method is applied to a wearable device and specifically includes the following steps:
Wherein, can confirm through the sensor module wearable equipment wears the wearing state when user's hand, the sensor module includes at least three proximity sensor, and every proximity sensor includes infrared emission end and infrared receiving terminal, can acquire every proximity sensor the infrared emission time stamp of infrared emission end with the time difference data between the infrared reception time stamp of infrared receiving terminal, and the basis time difference data is confirmed every proximity sensor corresponds the region with the first positional relationship of user's hand, wherein, above-mentioned first positional relationship can represent the distance information of every proximity sensor and user's hand.
Therefore, by 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 can be detected, and the communication quality is improved.
All antennas in the antenna module work according to the sequence of the communication priorities, 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 sequencing of the signal shielding levels and the antenna setting area of the antenna module on the wearable device. 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, according to the communication priority of the antenna module determined according to the wearing state, the proper antenna can be automatically selected for ultra-wideband communication, and the communication accuracy and efficiency are improved.
And step 403, controlling the on-off state 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 switched on, and the other switches are switched off. 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, according to the on-off state of the communication priority control switch module, the proper antenna can be selected for communication according to the wearing state, and the communication quality is improved.
And transmitting the ultra-wideband signal through the antenna with the highest priority in the antenna module to transmit the ultra-wideband signal.
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 a possible embodiment, the sensor module further includes an acceleration sensor, and 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 worn on the hand of the user can be obtained through the acceleration sensor, and a spatial motion trajectory 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 trajectory. The method is used for active interaction of the wearable device and the target device, such as interaction of waving instructions and the like.
It can be understood that the wearable device may periodically transmit UWB signals, the wearing state of the wearable device may be detected before each transmission, the communication priority of the antenna is determined according to the wearing state, the antenna with the highest priority is further called for ultra-wideband communication, if the ultra-wideband communication fails within a preset period, the antenna with the second priority may be called for ultra-wideband communication, if the ultra-wideband communication succeeds within the preset period, the second priority is adjusted to the highest priority, if the ultra-wideband communication fails within the preset period, the antenna with the third priority is switched again for ultra-wideband communication, if the ultra-wideband communication succeeds within the preset period, the third priority is adjusted to the highest priority, if the ultra-wideband communication fails within the preset period, the cycle is repeated, and the cycle is not repeated.
Therefore, through the method, the current wearing scene can be identified before ultra-wideband communication is carried out, reasonable antenna selection is carried out, so that the communication quality is improved, and the wearable equipment is small in size and convenient to carry, so that the cost is reduced, and meanwhile, the user experience can be greatly improved.
