[0060] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0061] The terms "first", "second", "third", "fourth" and the like (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0062] With the development of Internet of Things technology, users have higher and higher requirements for the communication quality of Internet of Things devices. Therefore, in order to ensure the communication quality and signal continuity, multiple antennas are usually installed on the Internet of Things devices to avoid the problem of being unable to communicate due to antenna damage and other situations when there is only one antenna on the Internet of Things device, but there is no replaceable spare antenna. However, when multiple antennas are installed on the Internet of Things device, if multiple antennas work at the same time, power consumption will increase and signal transmission and reception confusion will easily occur. Therefore, it is necessary to select one of the antennas to work. When selecting one of the antennas to work, the antenna with the best signal transmission and reception is usually selected. However, when the Internet of Things device selects an antenna, it is not sure which antenna has the best signal transmission and reception.

[0063] For example, for Figure 1 The vehicle shown has an internal antenna ( Figure 1 (not shown) and an external antenna. Figure 2 As shown, when the internal antenna or the external antenna is selected, the antenna interface is connected to the internal antenna or the external antenna, so that the internal antenna or the external antenna interacts with the wireless communication module to communicate with the outside world.

[0064] However, the vehicle's internal antenna is installed inside the vehicle, and the antenna signal will be weakened because it is wrapped in metal materials, and the external antenna is exposed to the outside and is also easily damaged, resulting in antenna signal weakening. Even if the vehicle's internal antenna and external antenna can both work, it is impossible to determine whether the internal antenna's receiving and transmitting signal is better than the external antenna, or the external antenna's receiving and transmitting signal is better than the internal antenna in the current environment of the vehicle.

[0065] Therefore, in order to solve the problems existing in the prior art, the present application proposes: Figure 3 As shown, the antenna is connected to the wireless communication module at the rising edge of the broken line 1, and the antenna is disconnected from the wireless communication module at the falling edge. The broken line 2 represents the signal of the antenna recognized by the wireless communication module.

[0066] In a networked device, when an antenna is connected to a wireless communication module, the wireless communication module cannot immediately recognize the signal of the antenna. After a time period of T1, the wireless communication module recognizes the signal of the antenna, and after a time period of T2, the wireless communication module recognizes the stable signal of the antenna. Correspondingly, when the antenna is disconnected from the wireless communication module, the wireless communication module cannot immediately recognize that the antenna is disconnected. After a time period of T3, the wireless communication module recognizes that the antenna is disconnected. Each time the antenna is connected or disconnected from the wireless communication module, the time periods T1, T2, and T3 are not fixed.

[0067] Therefore, when the antenna signal is stable, at least one signal strength of each of the multiple antennas is collected, the signal strength of each of the multiple antennas is processed, and the processed signal strength of each of the multiple antennas is compared to determine the antenna with better transceiver signal. This avoids the problem of blindly selecting an antenna, which may cause the selection of a damaged antenna or an antenna with poor transceiver signal quality due to uncertainty about the quality of the antenna's transceiver signal, thereby causing the inability to obtain external information in a timely and accurate manner due to the poor quality of the antenna's transceiver signal, and a poor user experience.

[0068] Figure 4 A flowchart of an antenna selection method provided in an embodiment of the present application. The method shown in the embodiment of the present application is applied to networked devices, such as mobile phones, vehicles, routers, communication modules, etc., and the embodiment of the present application is not limited to this. The execution subject of the embodiment of the present application is a networked device, specifically, a processor or chip in the networked device for controlling and processing antenna-related data, and the embodiment of the present application is not limited to this. Figure 4 As shown, the method shown in the embodiment of the present application includes:

[0069] S401. Obtain at least one first signal strength of each of N antennas.

[0070] Wherein, N is a positive integer greater than or equal to 2.

[0071] In this embodiment, a built-in antenna and an external antenna in a vehicle are taken as examples for description.

[0072] After the vehicle is started, when the wireless signal module detects that the signal strength CSQ is not 0, the vehicle's built-in antenna is connected to the wireless communication module. When the signal strength of the built-in antenna is stable, the wireless communication module collects at least one first signal strength of the built-in antenna and sends at least one first signal strength of the built-in antenna to the processor.

[0073] Then the internal antenna is switched to the external antenna, and when the signal strength of the external antenna is stable, the wireless communication module collects at least one first signal strength of the external antenna and sends the at least one first signal strength of the external antenna to the processor. Figure 5 The flow chart for collecting signal strength for the wireless communication module is as follows: Figure 5 As shown:

[0074] S501: Determine whether the signal strength of the antenna enters a stable state.

[0075] In this embodiment, for the built-in antenna, such as Figure 3 As shown, when the duration of connection between the built-in antenna and the wireless communication module reaches t1, or when the fluctuation of the signal strength is detected twice in a row within the first preset range, it is determined that the signal strength of the built-in antenna enters a stable state.

[0076] Wherein, t1 is greater than or equal to the duration of the wireless communication module recognizing the stable signal strength of the built-in antenna. For example, t1 is greater than or equal to Figure 3 In practice, t1 is, for example, 50 seconds.

[0077] The first preset range is, for example, a range between 0 and a fourth preset value, wherein the fourth preset value is, for example, 8 dB.

[0078] In addition, since the internal antenna is located inside the vehicle and the external antenna is located outside the vehicle, when the connection between the external antenna and the wireless communication module is switched to the connection between the internal antenna and the wireless communication module, if the signal strength no longer decreases within t2, it is determined that the signal strength of the internal antenna has entered a stable state. In practice, t2 is, for example, 20 seconds.

[0079] For external antennas, such as Figure 3 As shown, when the duration of connection between the external antenna and the wireless communication module reaches t3, or when the fluctuation of the signal strength is detected twice in succession within the second preset range, it is determined that the signal strength of the external antenna enters a stable state.

[0080] Wherein, t3 is greater than or equal to the duration of the wireless communication module recognizing the stable signal strength of the external antenna. For example, t3 is greater than or equal to Figure 3 In practice, t3 is, for example, 50 seconds.

[0081] The second preset range is, for example, a range between 0 and a fourth preset value, wherein the fourth preset value is, for example, 8 dB.

[0082] In addition, since the internal antenna is located inside the vehicle and the external antenna is located outside the vehicle, when the connection between the internal antenna and the wireless communication module is switched to the connection between the external antenna and the wireless communication module, if the signal strength no longer increases within t4, it is determined that the signal strength of the external antenna has entered a stable state. In practice, t4 is, for example, 20 seconds.

[0083] When a large signal strength fluctuation occurs during the process of collecting the signal strength of the built-in antenna or the signal strength of the external antenna, for example, when the vehicle enters a tunnel, if the signal strength still does not reach a stable state within t5, signal strength collection also begins.

[0084] It should be noted that the specific values ​​of t1, t2, t3, t4, t5, the first preset range, the second preset range and the fourth preset value are only given as a specific embodiment and can be set according to actual needs in practical applications.

[0085] S502: Continuously acquire at least one signal strength of each of the N antennas from back to front according to the acquisition time of at least one signal strength of the antenna.

[0086] In this embodiment, a built-in antenna is taken as an example for description.

[0087] When the built-in antenna is connected to the wireless communication module, according to the change law of the signal strength, as the access time increases, the signal strength becomes more and more stable. Therefore, when collecting the signal strength of the built-in antenna, according to the time when the signal strength is received, the signal strength is collected from the later time forward. For example, when collecting the signal strength in the time period 10:00:00-10:01:00, the signal strength is collected from the signal strength at 10:01:00 to 10:00:00 every preset time length to obtain the signal strength of at least one built-in antenna.

[0088] S503: If the difference between two consecutive signal strengths is greater than or equal to a fourth preset value, stop acquiring the signal strength of the built-in antenna.

[0089] In this embodiment, a built-in antenna is taken as an example for description.

[0090] When collecting from the back to the front according to the time of receiving signal strength, if the difference between two consecutively collected signal strengths is greater than or equal to the fourth preset value, the collection is stopped, the collected signal strength of the built-in antenna is saved, and the signal strength with the previous receiving time is no longer collected. The specific value of the fourth preset value can be determined according to actual conditions, for example, the fourth preset value is 8dB.

[0091] It should be noted that when collecting the signal strength of each antenna, due to the influence of factors such as the external environment on the antenna signal, the number of signal strengths collected for different antennas among multiple antennas may be different. For example, the number of signal strengths collected by the built-in antenna is 10, and the number of signal strengths collected by the external antenna is 7.

[0092] S402: Calculate an average signal strength of each antenna according to at least one first signal strength of each antenna.

[0093] In this embodiment, for each antenna among N antennas, for example, a built-in antenna in a vehicle, after obtaining at least one first signal strength of the built-in antenna, an average signal strength of the built-in antenna is calculated according to the at least one first signal strength of the built-in antenna.

[0094] The average signal strength is, for example, the average value of at least one first signal strength. For example, the signal strength of the built-in antenna is C 1 , C 2 , C 3 , then the average signal strength is Alternatively, the average signal strength is, for example, a weighted average of at least one first signal strength. For example, according to the acquisition time of the signal strength, the closer the time is to the current time, the greater the weight of the signal strength. The signal strength of the built-in antenna is C 1 , weight is S 1 , the signal strength is C 2 , weight is S 2 , the signal strength is C 3 , weight is S 3 , then the average signal strength is C = S 1 ×C 1 +S 2 ×C 2 +S 3 ×C 3 .

[0095] For other antennas, the calculation is performed in the above manner, and the method for calculating the average signal strength among the N antennas is consistent.

[0096] S403: Determine a target antenna from the N antennas according to the average signal strength of each antenna in the N antennas, so as to communicate with the network device through the target antenna.

[0097] In this embodiment, after obtaining the average signal strength of each of the N antennas, the average signal strength of each of the N antennas is compared to determine the target antenna for communication between the network device and the network device, and the antenna in the network device is switched to the target antenna.

[0098] Exemplarily, if the difference between the average signal strengths of any two antennas among the N antennas is greater than or equal to a first preset value, the antenna with the largest average signal strength among the N antennas is determined as the target antenna, wherein the first preset value is, for example, 7 dB.

[0099] The average signal strength of each antenna in the N antennas is compared in pairs to obtain the difference between the average signal strengths of any two antennas. If the difference between the average signal strengths of any two antennas is greater than a first preset value, it can be determined that there is a damaged antenna in the N antennas. At this time, the antenna with the largest average signal strength among the N antennas is used as the target antenna and the antenna is used for communication. The first preset value can be set according to actual needs, and this application does not limit this.

[0100] In this embodiment, at least one first signal strength of each of the N antennas is obtained through the wireless communication module; the average signal strength of each antenna is calculated based on the at least one first signal strength of each antenna; and the antenna with better signal strength is determined as the target antenna from the N antennas based on the average signal strength of each of the N antennas, so as to communicate with the network device through the target antenna. In this way, external information can be obtained in a timely and accurate manner, avoiding the problem of being unable to obtain external information in a timely and accurate manner due to poor quality of the signal received and sent by the selected antenna due to uncertainty about the quality of the signal received and sent by the antenna when blindly selecting the antenna. It can also avoid communication interruption during the communication process, thereby improving the user experience.

[0101] exist Figure 4 The embodiment shown is to perform one round of traversal to determine the target antenna. The communication antenna determined in this way is accidental. Therefore, in order to increase the probability that the determined antenna is the antenna with better signal transmission and reception among the N antennas, two rounds of traversal are usually required, such as Figure 6 As shown, the method includes:

[0102] S601: Obtain at least one first signal strength of each of N antennas.

[0103] In this embodiment, the specific implementation of S601 may refer to S401 and will not be described in detail here.

[0104] It should be noted that when acquiring the signal strength of each antenna in the first round, it is necessary to acquire it when the signal strength of the antenna is stable. When switching antennas, if you switch to one of the antennas, when the preset time is reached, for example, after switching, when the time the antenna is connected to the wireless communication module reaches t1, the wireless communication module still does not detect the signal strength of the antenna, which means that the antenna is damaged, or that the antenna currently does not have the ability to send and receive signals, so it is switched to another antenna. Thereafter, in order to save antenna selection time, the signal strength of the antenna is no longer collected during this round of collecting antenna signal strength.

[0105] S602: Calculate a first average signal strength of each antenna according to at least one first signal strength of each antenna.

[0106] In this embodiment, the specific implementation of S602 may refer to S402 and will not be described in detail here.

[0107] S603, determine whether the difference between the first average signal strengths of any two antennas among the N antennas is greater than or equal to a first preset value, if so, execute S604 or S611; if so, execute S605.

[0108] In this embodiment, the specific implementation of S603 can refer to S403, which will not be repeated here. That is, if the difference between the first average signal strengths of any two antennas is greater than or equal to the first preset value, it can be determined that there is a damaged antenna among the N antennas, and then S611 is executed to select the antenna with better first average signal strength as the communication antenna.

[0109] However, in actual applications, there may be a situation where the difference between the first average signal strengths of any two antennas among the N antennas is greater than or equal to the first preset value, but each antenna can send and receive signals, but the ability to send and receive signals among the N antennas varies greatly.

[0110] Furthermore, since the ability of an antenna to send and receive signals may fluctuate due to external interference, such as weather influence, the first antenna having the largest average signal strength does not mean that the antenna has the best ability to send and receive signals among the N antennas.

[0111] Therefore, if the difference between the first average signal strengths of any two antennas among the N antennas is greater than or equal to the first preset value, the antenna with the largest first average signal strength is selected as the communication antenna, and the selected antenna may not be the antenna with the best signal receiving and sending capability among the N antennas. Therefore, in order to more accurately select the antenna with the best signal receiving and sending capability among the N antennas, S604 may be executed.

[0112] If the difference between the first average signal strengths of two antennas among the N antennas is less than the first preset value, it means that at least two antennas among the N antennas are antennas that can send and receive signals. At this time, a second round of obtaining the signal strength of each antenna among the N antennas is required to execute S605.

[0113] Among them, the first preset value can be set according to actual needs. For example, in this embodiment, the first preset value is 7dB, and this application does not impose any limitation on this.

[0114] S604: Determine whether the first average signal strength of each antenna is greater than or equal to a second preset value, and whether the number of first signal strengths collected by each antenna is greater than or equal to a preset number. If so, execute S605; if not, execute S611.

[0115] In this embodiment, it is determined whether the first average signal strength of each antenna is greater than or equal to a second preset value. If the number of collected first signal strengths of the antennas is too small, the accuracy of the result will be affected. Therefore, it is also necessary to determine whether the number of collected first signal strengths of each antenna is greater than or equal to a preset number.

[0116] Among them, the second preset value is, for example, 13dB, and the preset number is, for example, 2. In practical applications, it can be set according to actual needs, and this application does not impose any restrictions on this.

[0117] When the first average signal strength of each antenna is greater than or equal to the second preset value, and the number of collected first signal strengths of each antenna is greater than or equal to the preset number, it means that each of the current N antennas can send and receive signals and the antennas send and receive signals stably. At this time, it is necessary to collect the second round of antenna signal strengths, that is, execute S605; otherwise, execute S611.

[0118] S605: Obtain at least one second signal strength of each of the N antennas.

[0119] In this embodiment, the specific implementation of S605 may refer to S401 and will not be described in detail here.

[0120] It should be noted that, in order to save time in selecting antennas during the second round of collecting antenna signal strengths, the antenna signal strengths may be collected after the antennas are switched, and there is no need to collect the signals when the signal strengths are stable.

[0121] S606: Calculate a second average signal strength of each antenna according to at least one second signal strength of each antenna.

[0122] In this embodiment, the specific implementation of S606 may refer to S402 and will not be described in detail here.

[0123] S607, determine whether the difference between the second average signal strengths of any two antennas among the N antennas is greater than or equal to a third preset value, if so, execute S608; if not, execute S609.

[0124] In this embodiment, the second average signal strengths of any two antennas among the N antennas are compared pairwise to obtain the difference between the second average signal strengths of any two antennas. If the difference between the second average signal strengths of any two antennas is greater than the third preset value, S608 is executed; otherwise, S609 is executed.

[0125] Among them, the third preset value is, for example, 2dB. In practical application, it can be set according to actual needs, and this application does not impose any limitation on this.

[0126] S608: Determine the antenna with the largest second average signal strength among the N antennas as the target antenna.

[0127] In this embodiment, the antenna with the largest second average signal strength among the N antennas is determined as the target antenna, and the antenna is used for communication.

[0128] S609: Calculate the signal strength variance of each of the N antennas.

[0129] In this embodiment, if the difference between the second average signal strengths of any two antennas among the N antennas is less than the third preset value, it means that there is no significant difference between the capabilities of the N antennas to send and receive signals. At this time, the signal strength variance of each antenna is calculated based on the second average signal strength of each antenna, and the antenna with better stability is selected as the communication antenna.

[0130] S610: Determine a target antenna from the N antennas according to a signal strength variance of each of the N antennas.

[0131] In this embodiment, the variance can reflect the fluctuation of signal strength. The smaller the variance, the more stable the antenna's ability to send and receive signals. Therefore, the antenna with the smallest signal strength variance is determined as the target antenna to avoid signal fluctuations when the antenna sends and receives signals, thereby affecting communication quality.

[0132] S611. Determine an antenna with the largest first average signal strength among N antennas as a target antenna, so as to communicate with a network device through the target antenna.

[0133] In this embodiment, the antenna with the largest second average signal strength among the N antennas is determined as the target antenna, and the antenna is used for communication.

[0134] In this embodiment, in the first round of traversal, at least one first signal strength of each antenna in the N antennas is obtained, and the first average signal strength of each antenna is calculated according to the at least one first signal strength of each antenna. When the difference between the first average signal strengths of two antennas in the N antennas is less than the first preset value, and / or the first average signal strength of each antenna is greater than or equal to the second preset value, and the number of second signal strengths of each antenna is greater than or equal to the preset number, a second round of traversal is performed, that is, at least one second signal strength of each antenna in the N antennas is obtained, and the second average signal strength of each antenna is calculated according to the at least one second signal strength of each antenna. If the difference between the second average signal strengths of any two antennas in the N antennas is greater than or equal to the third preset value, the antenna with the largest second average signal strength among the N antennas is determined as the target antenna; otherwise, the signal strength variance of each antenna in the N antennas is calculated, and the target antenna is determined from the N antennas according to the signal strength variance of each antenna in the N antennas. Through two rounds of traversal, the probability that the antenna finally determined for communication is the best antenna among N antennas is increased, the communication quality is improved, thereby avoiding communication interruption during the communication process and improving the user experience.
