[0042] The core of the present application is to provide an antenna abnormality detection method, device, electronic device and computer-readable storage medium, so as to comprehensively and effectively detect various antenna failure problems without increasing device cost and size space.

[0043] In order to describe the technical solutions in the embodiments of the present application more clearly and completely, the technical solutions in the embodiments of the present application will be introduced below in conjunction with the drawings in the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0044] The current antenna detection solution usually sets a ground resistor on the antenna and a pull-up resistor on the communication product module end, thereby identifying whether the antenna connection is disconnected by the level of the antenna port. Figure 1 As shown in the figure, this detection scheme adds an additional grounding resistor R1 on the basis of a conventional antenna; and uses another resistor R0 to pull up to the high level VCC at the product module end, and connects to the GPIO end of the MCU in the wireless communication device. By reasonably setting the resistance value relationship between R1 and R0, when the antenna connection is normal, VCC can be divided by resistors to generate a low level on the MCU GPIO line; and when the antenna connector is disconnected, the MCU GPIO is pulled up to a high level. In this way, when the MCU detects a high level, it can determine that the antenna connection is disconnected.

[0045] Since this method requires additional resistors, the antenna needs to be specially customized, and the product side also needs specific circuits to cooperate, so the cost is relatively high; at the same time, for wireless communication products with multiple antenna function ports, this method will obviously increase the size of the product circuit. In addition, this method can only detect whether the antenna is successfully connected, but cannot effectively detect damage to the antenna body and the snap-fit ​​effect. In view of this, the present application provides an antenna abnormality detection solution that can effectively solve the above problems.

[0046] See also Figure 2As shown, the embodiment of the present application discloses an antenna abnormality detection method, which is applied to wireless communication equipment and mainly includes:

[0047] S101: Control each antenna to scan each frequency point in the frequency point list, and respectively record the acquired signal reception strength values.

[0048] S102: Compare the difference between the signal reception strength value of the current antenna at the current frequency and the signal reception strength effective threshold value of the wireless communication device.

[0049] S103: If the difference between the signal receiving strength value and the signal receiving strength effective threshold value reaches the antenna performance difference threshold value, it is determined that the current antenna is abnormal.

[0050] Specifically, the antenna anomaly detection method provided in the embodiment of the present application is based on the original hardware design, without adding any additional components, to achieve antenna anomaly detection by software detection. Among them, the main process of the software detection method for antenna anomaly problems is to control the wireless communication equipment to capture the radio wave energy that exists everywhere in the wireless network environment, and then compare the signal strength received by each antenna function port, so as to identify the abnormal antenna.

[0051] The present application can pre-set the various signal frequencies to be scanned to capture signals, forming a frequency list. Generally, most current wireless communication devices are equipped with multiple antenna function ports, each of which corresponds to an antenna. For each antenna at each antenna function port, it can be controlled to scan at each frequency in the frequency list to capture signals, and record the signal reception strength value captured by the antenna after scanning at each frequency, that is, the RSSI (Received Signal Strength Indicator) value.

[0052] Among them, the RSSI value is an indication of the strength of the received signal, and is a quantitative reflection of the effectiveness of the antenna in achieving the signal receiving and sending functions. Under the same circumstances (the antenna model and installation location are the same, and the signal capture results of the same signal source are analyzed), the larger the received RSSI value, the better the performance of the corresponding antenna; the smaller the received RSSI value, the worse the performance of the corresponding antenna. When it is low to a certain extent, it can be considered that the antenna is faulty or other abnormal conditions.

[0053] This application pre-sets a parameter of signal receiving strength effective threshold value as a comparison standard value for the RSSI value obtained after scanning each antenna at each frequency point. If a certain RSSI value is much smaller than the signal receiving strength effective threshold value, the antenna can be determined to be abnormal. Considering that the antenna itself will have performance differences within a certain reasonable range during installation and design, this application also sets a parameter of antenna performance difference threshold value. In this way, in theory, the RSSI values ​​obtained by normal antennas will be slightly different from each other, but the difference value should be less than the antenna performance difference threshold value.

[0054] In this way, the present application can use the antenna performance difference threshold value to measure and compare the difference between the RSSI value of each antenna and the effective threshold value of the signal reception strength: if the RSSI value of an antenna is less than the difference between the effective threshold value of the signal reception strength, that is, the difference is less than the antenna performance difference threshold value, then it means that the RSSI value of the antenna is already lower than the reasonable range of the RSSI value corresponding to the normal antenna, and then the antenna can be judged to be abnormal.

[0055] Since the RSSI value is a quantitative reflection of the effectiveness of the antenna in achieving the signal receiving and sending functions, the present application uses the RSSI value obtained by scanning and capturing the antenna signal as the detection basis, and can effectively detect various abnormal problems of the antenna, including situations where the antenna performance drops significantly due to disconnection or insufficient connection, damage to the antenna body, antenna short circuit, etc.

[0056] It can be seen that the antenna abnormality detection method provided in the present application realizes effective detection of various abnormal problems of the antenna by software detection without adding additional circuit components. It not only avoids the increase of circuit cost and layout space, but also effectively improves the detection capability and efficiency of antenna abnormalities, thereby greatly improving the user experience.

[0057] As a specific embodiment, the antenna abnormality detection method provided in the embodiment of the present application controls each antenna to scan according to each frequency point in the frequency point list on the basis of the above content, including:

[0058] The antennas with the same applicable frequency band are divided into the same group of antennas;

[0059] A frequency list is set for each group of antennas within the applicable frequency band of the group;

[0060] Each group of antennas is controlled in groups to scan according to each frequency point in the frequency point list of this group.

[0061] Specifically, many wireless communication devices are equipped with multiple antenna function ports to connect multiple antennas. The frequency supported by the antenna itself and the receiving frequency band supported by its antenna function port cooperate to jointly determine the applicable frequency band range of the antenna. In this embodiment, the antennas can be grouped in advance, and antennas with the same applicable frequency band range will be divided into the same group.

[0062] For example, see Figure 3 , the applicable frequency band range of antennas A0, A1, ..., An is 700-960 MHz (such as LTE B5, B8, etc.), so these antennas are classified into the same group - Group A; the applicable frequency band range of antennas B0, B1, ..., Bn is 1805-2170 MHz (such as LTE B1, B3, etc.), so these antennas are classified into the same group - Group B.

[0063] In this embodiment, a frequency list can be set for each group of antennas to set the frequency channels and other information that the antennas need to scan. Of course, each frequency list is within the applicable frequency band of the antennas. For example, the receiving frequencies of 935MHz (scanning bandwidth 20MHz) and 955MHz (scanning bandwidth 20MHz) based on B8 can be set for the antennas of group A; the receiving frequencies of 2120MHz (scanning bandwidth 20MHz), 2130MHz (scanning bandwidth 20MHz) and 2150MHz (scanning bandwidth 20MHz) based on B1 can be selected for the antennas of group B.

[0064] In this way, when the wireless communication equipment is turned on and ready for antenna anomaly detection, the antenna group information list and the frequency list of each group of antennas can be extracted. Each time an antenna group is selected, all antennas under the group can be controlled to scan at their corresponding frequencies to capture signals.

[0065] As a specific embodiment, the antenna abnormality detection method provided in the embodiment of the present application is based on the above content, and before comparing the difference between the signal reception strength value of the current antenna at the current frequency and the signal reception strength effective threshold value of the wireless communication device, it also includes:

[0066] Determine the maximum value of the signal receiving strength of the antenna group at the current frequency;

[0067] Determine whether the maximum value is greater than the effective threshold value of the signal receiving strength;

[0068] If yes, then compare the difference between the signal receiving strength value of the current antenna at the current frequency and the signal receiving strength effective threshold value of the wireless communication device and the subsequent steps;

[0069] If not, it is determined that the signal receiving strength values ​​of the antenna group at the current frequency point are all invalid, and the scanning of the next frequency point is continued.

[0070] Specifically, the present application controls the wireless communication device to capture the radio wave energy that exists everywhere in the wireless network environment to compare the signal reception strength values. In order to ensure that the received signal is indeed the signal captured by the antenna from a certain wireless signal source, and not the result of thermal noise fluctuations of the wireless communication device itself, the present application also judges the validity of the RSSI value of each group of antennas.

[0071] Specifically, for the same group of antennas, if the maximum value of the RSSI values ​​obtained by the antennas in this group in this scan is valid, that is, the maximum value of the RSSI values ​​in this group is greater than the valid threshold value of the signal receiving strength, it can be said that a signal from a wireless signal source can indeed be received in this scan, so the RSSI values ​​received by the antennas in this group are all valid. On this basis, the difference between the RSSI values ​​of each antenna and the valid threshold value of the signal receiving strength can be further determined and compared.

[0072] On the contrary, if the maximum values ​​of the RSSI values ​​of this group of antennas are all less than the effective threshold value of the signal receiving strength, then each RSSI value of this group of antennas is less than the effective threshold value of the signal receiving strength. In this way, it can be determined that the current scan of this group of antennas is invalid and the next frequency point can be scanned.

[0073] As a specific embodiment, the antenna anomaly detection method provided in the embodiment of the present application is based on the above content, and the difference between the effective threshold value of the signal reception strength and the thermal noise of the wireless communication device is at least 10dB.

[0074] Specifically, the effective threshold value Sth dBm of the signal receiving strength needs to be set according to the thermal noise level of the wireless communication product itself. Generally, the value of Sth dBm can be set to be 10 to 20 dB higher than the thermal noise of the whole device.

[0075] In addition, it should be noted that the thermal noise of the wireless communication equipment may be different under different frequency bands, and the normal performance differences between different antennas may also be different. Therefore, those skilled in the art can set corresponding signal reception strength effective threshold values ​​and corresponding antenna performance difference threshold values ​​for each antenna group to further improve the detection accuracy; of course, the same signal reception strength effective threshold value and the same antenna performance difference threshold value can also be used for each antenna group, and this application does not limit this.

[0076] As a specific embodiment, the antenna abnormality detection method provided in the embodiment of the present application further includes:

[0077] After the scan is completed, the information of all abnormal antennas will be reported.

[0078] Specifically, after all antenna groups have completed scanning and diagnosis of their respective frequency point lists, all recorded abnormal antennas can be reported to the user so that the user can perform maintenance and processing in a timely manner.

[0079] As a specific embodiment, the antenna abnormality detection method provided in the embodiment of the present application further includes:

[0080] Temporarily prohibit the use of all abnormal antennas.

[0081] Specifically, in order to prevent the abnormal antenna from continuing to work and affecting the overall performance of the wireless communication device, after identifying the abnormal antenna, this embodiment can further set the abnormal antenna to a temporarily prohibited use state through a software method. For example, for a 4MIMO (multiple-in multiple-out) antenna, the initial report is a 4MIMO network. However, if 2 antennas are abnormal, and only 2 antennas are actually working, and the network still transmits and processes according to the 4-antenna method initially reported, the information of 2 antennas will be lost, and the demodulation process will have problems, seriously affecting the transmission rate (even much worse than the rate of 2MIMO). If the problem of the abnormality of these two antennas is discovered in time through antenna abnormality detection, and 4MIMO is disabled in the software in time and a good 2MIMO transmission method is adopted, the impact of antenna abnormality on data communication can be effectively reduced.

[0082] The above content can be compared with Figure 4 , Figure 4 Another antenna abnormality detection method is disclosed in an embodiment of the present application, including:

[0085] S203: Select a group of antennas, control the antennas in the group to scan according to each frequency point in the frequency point list, and respectively record the obtained signal reception strength values.

[0086] S204: Determine the maximum value of the signal reception strength of the antenna group at the current frequency.

[0087] S205: Determine whether the maximum value of the antenna group is greater than the effective threshold value of the signal receiving strength; if so, proceed to S206; if not, proceed to S208.

[0088] S206: Calculate the difference between the signal receiving strength value of each antenna in the group and the signal receiving strength effective threshold value; and proceed to S207.

[0089] S207: Identify the antenna whose difference is greater than the antenna performance difference threshold as an abnormal antenna; and proceed to S208.

[0090] S208: Determine whether the frequency point list of the antenna group has been scanned; if so, proceed to S209; if not, proceed to S209.
