Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The antenna anomaly detection method provided by the application can be applied to the application environment shown in fig. 1. Wherein the terminal 102 communicates with the server 104 via a network. The terminal 102 firstly communicates with at least two auxiliary terminals based on a first radio frequency parameter, and acquires a first received signal strength reported by the at least two auxiliary terminals; wherein the terminal to be detected and the at least two auxiliary terminals are selected from a plurality of terminals capable of communicating with each other; the terminal to be detected determines whether the terminal to be detected and each auxiliary terminal have an abnormal antenna based on the first received signal strength reported by the at least two auxiliary terminals, and the terminal 102 sends an abnormal detection result to the server 104. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server 104 may be implemented by an independent server or a server cluster formed by a plurality of servers.

As shown in fig. 2, a plurality of terminals 204 capable of communicating with each other form a distributed network. Also included in the distributed network is a base station 202 that communicates with a number of terminals.

In an embodiment, as shown in fig. 3, an antenna anomaly detection method is provided, which is described by taking the application of the method to the terminal in fig. 1 as an example, and includes the following steps:

s302: the method comprises the steps that a terminal to be detected communicates with at least two auxiliary terminals based on first radio frequency parameters, and first received signal strength reported by the at least two auxiliary terminals is obtained; wherein the terminal to be detected and the at least two auxiliary terminals are selected from a plurality of terminals capable of communicating with each other.

When antenna abnormity detection is carried out on a certain terminal, the terminal is used as equipment to be detected, and at least two other terminals capable of communicating with each other are selected as auxiliary terminals.

When antenna abnormity detection is carried out on a plurality of terminals, the sequence of terminal detection needs to be set, equipment to be detected is determined according to the set sequence, and at least two other terminals capable of communicating with each other are used as auxiliary terminals.

In general, the number of the auxiliary detection devices is not less than two, and the specific number can be set according to actual requirements.

S304: and the terminal to be detected determines whether the terminal to be detected and each auxiliary terminal have abnormal antennas or not based on the first received signal strength reported by the at least two auxiliary terminals.

It can be understood that, when the terminal to be detected has an abnormal antenna, the first received signal strength is also abnormal, so that whether the terminal to be detected and each of the auxiliary terminals have an abnormal antenna can be determined according to the first received signal strengths reported by at least two auxiliary terminals.

Because the distance between the terminal to be detected and the auxiliary terminal is far smaller than the distance between the terminal to be detected and the base station, the possibility that obstacles or signal interference and the like exist between the base station and the terminal to be detected can be reduced, and therefore the detection accuracy can be improved.

In an embodiment, when a plurality of terminals to be detected are provided, all terminals need to be powered on before antenna detection, and after the power is turned on, the terminals respond to the device search request and reply their own serial number information by using a network broadcast device search request. If a terminal does not receive the serial number information of other terminals in the cluster network, the network needs to be checked.

Each terminal stores own serial number information, sorts all the serial number information according to the size of the serial number according to the received serial number information of other terminals, and then determines the detection priority of the terminal.

In an embodiment, the terminal with the minimum serial number preferentially gains the antenna detection authority, and it is understood that in some other embodiments, the terminal with the maximum serial number may also be set to have the limited antenna detection authority.

After the first terminal to be detected completes detection, the first terminal to be detected with the testing authority can hand over the authority to the terminal with the second priority in a broadcasting mode, and then the terminal can be switched into an antenna detection mode. Particularly, if a certain antenna of the terminal of the next priority is already calibrated to be abnormal in antenna detection, the terminal does not possess the antenna test authority and is directly handed over to the terminal of the next priority.

In an embodiment, the first rf parameter is an rf parameter whose signal interference satisfies a preset condition when the terminal to be detected wirelessly communicates with the at least two auxiliary terminals.

It can be understood that although the communication distance between the terminal to be detected and each auxiliary terminal is relatively close, there is still a possibility of signal interference, and if the antenna abnormality of the terminal to be detected is detected under the condition of signal interference, the detection result is not accurate. Therefore, in this embodiment, the first radio frequency parameter is selected, where the signal interference satisfies the preset condition when the terminal to be detected communicates with each auxiliary terminal, so as to improve the accuracy of detection.

Specifically, as shown in fig. 4, the first rf parameter is obtained by the following method:

s402: broadcasting a second radio frequency parameter by the terminal to be detected, and indicating all other terminals in the plurality of terminals to receive signals by the second radio frequency parameter within a preset time period without sending signals;

s404: and the terminal to be detected acquires the second received signal strength reported by each auxiliary terminal within the preset time period, and takes the second radio frequency parameter as the first radio frequency parameter under the condition that the second received signal strength reported by each auxiliary terminal is smaller than a first preset threshold value.

It should be noted that the terminal to be detected broadcasts the second rf parameter, so that other terminals can also receive signals based on the second rf parameter. It can be understood that, if there is signal interference in the frequency band where the second rf parameter is located, the other terminals can receive the interference data based on the second rf parameter. And under the condition that the second received signal strength reported by each auxiliary terminal is smaller than a first preset threshold, the second radio frequency parameter is used as the first radio frequency parameter to improve the accuracy of antenna abnormality detection, which indicates that the signal interference is small or nonexistent and cannot influence the first received signal strength.

In an embodiment, when the second received signal strength reported by any one of the auxiliary terminals is greater than the first preset threshold, after the terminal to be detected re-determines the second radio frequency parameter, the step of determining, by the terminal to be detected, the first radio frequency parameter whose signal interference satisfies the preset condition when performing wireless communication with at least two auxiliary terminals is performed.

Each antenna has a separate set of radio frequency parameters. The independent radio frequency parameter set means that only the antenna can transmit a radio signal with a certain bandwidth and a certain channel, other terminals cannot normally transmit and receive the radio signal, and only the radio frequency parameters used by broadcasting in the network can normally transmit and receive the radio signal.

And when the second radio frequency parameter does not meet the preset condition, reselecting and determining a new second radio frequency parameter from the radio frequency parameter set, and repeating the step of determining the first radio frequency parameter meeting the preset condition by the terminal to be detected when the terminal to be detected determines the wireless communication with at least two auxiliary terminals, until the first radio frequency parameter meeting the preset condition is determined.

In an embodiment, when the number of the antennas of the terminal is multiple, the first radio frequency parameter is a radio frequency parameter of at least one antenna of each terminal for transmitting and receiving signals; the method for determining whether the terminal to be detected and each auxiliary terminal have abnormal antennas comprises the following steps of:

and the terminal to be detected determines whether the at least one antenna of the terminal to be detected and each auxiliary terminal is an abnormal antenna or not based on the first received signal strength reported by the at least two auxiliary terminals.

It can be understood that some terminals have at least one antenna, and the terminal to be detected determines whether the terminal to be detected and the at least one antenna of each auxiliary terminal are abnormal antennas based on the first received signal strength reported by the at least two auxiliary terminals, so as to implement antenna abnormality detection on the terminal of the at least one antenna.

And when all the antennas of the terminal to be detected detect or abnormal antennas are detected, the antenna abnormality detection is not carried out on the detection terminal.

In an embodiment, the determining, by the terminal to be detected, whether the at least one antenna of the terminal to be detected and each of the auxiliary terminals is an abnormal antenna based on the first received signal strength reported by the at least two auxiliary terminals includes:

under the condition that the first received signal strength reported by the at least two auxiliary terminals is greater than a second preset threshold corresponding to each auxiliary terminal, the terminal to be detected determines that the terminal to be detected and the at least one antenna of each auxiliary terminal are normal antennas; and/or

And under the condition that the first received signal strength reported by a first auxiliary terminal of the at least two auxiliary terminals is greater than a second preset threshold corresponding to the first auxiliary terminal, and the first received signal strength reported by a second auxiliary terminal of the at least two auxiliary terminals is less than a second preset threshold corresponding to the second auxiliary terminal, the terminal to be detected determines that the terminal to be detected and the at least one antenna of the first auxiliary terminal are normal antennas, and the terminal to be detected determines that the at least one antenna of the second auxiliary terminal is an abnormal antenna.

In an embodiment, the determining, by the terminal to be detected, whether the at least one antenna of the terminal to be detected and each of the auxiliary terminals is an abnormal antenna based on the first received signal strength reported by the at least two auxiliary terminals further includes:

and the terminal to be detected sequentially takes the radio frequency parameters in the radio frequency parameter set as first radio frequency parameters, and determines that the terminal to be detected and the at least one antenna of each auxiliary terminal are in an unknown state under the condition that the first received signal strength reported by the at least two auxiliary terminals is smaller than a second preset threshold corresponding to each auxiliary terminal.

It can be understood that, when the first signal reception strength is greater than the corresponding preset threshold, it indicates that the to-be-detected antenna of the to-be-detected terminal and the transmission antenna of the corresponding auxiliary terminal are normal; and when the first signal receiving intensity is smaller than the corresponding preset threshold value, it indicates that at least one of the antenna to be detected of the terminal to be detected and the transmission antenna of the corresponding auxiliary terminal is abnormal.

It is understood that the second preset threshold is related to the distance between the terminal to be detected and the corresponding auxiliary terminal, and therefore the second preset threshold is determined based on the distance between the terminal to be detected and the corresponding auxiliary terminal.

In an embodiment, the terminal to be detected performs antenna anomaly detection on each antenna of the terminal to be detected and each auxiliary terminal based on the first radio frequency parameter corresponding to each antenna, respectively, and the method further includes:

determining that no antenna abnormal fault exists in the terminal to be detected or each auxiliary terminal under the condition that all antennas of the terminal to be detected or each auxiliary terminal are not abnormal antennas;

and determining that the antenna abnormal fault exists in the terminal to be detected or each auxiliary terminal under the condition that any antenna of the terminal to be detected or each auxiliary terminal is an abnormal antenna.

In an embodiment, as shown in fig. 5, after the terminal to be detected determines whether the antennas of the terminal to be detected and each of the auxiliary terminals are abnormal antennas based on the first received signal strengths reported by the at least two auxiliary terminals, the method further includes:

s306: selecting a new terminal to be detected and at least two auxiliary terminals of the new terminal to be detected from the plurality of terminals, and performing antenna anomaly detection on the new terminal to be detected, wherein the new terminal to be detected is a terminal which is not detected to have an anomalous antenna at present except the terminal to be detected from the plurality of terminals.

In this embodiment, a new terminal to be detected and at least two auxiliary terminals of the new terminal to be detected are selected from the plurality of terminals, so that mutual antenna abnormality detection between the terminals is realized.

It should be understood that although the various steps in the flow charts of fig. 1-5 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 1-5 may include multiple steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, which are not necessarily performed in sequence, but may be performed in turn or alternately with other steps or at least some of the other steps.

and the terminal to be detected determines whether the terminal to be detected and each auxiliary terminal have abnormal antennas or not based on the first received signal strength reported by the at least two auxiliary terminals.

In an embodiment, the first radio frequency parameter is a radio frequency parameter whose signal interference satisfies a preset condition when the terminal to be detected wirelessly communicates with the at least two auxiliary terminals.
