Detailed Description
The core of the application is to provide an antenna connection detection method, which can reduce detection cost and improve detection accuracy. Another core of the present application is to provide an antenna connection detecting apparatus, a device and a computer readable storage medium, all having the above technical effects.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, 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 some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
Example one
Referring to fig. 2, fig. 2 is a schematic flowchart of an antenna connection detection method according to an embodiment of the present application, and referring to fig. 2, the method mainly includes:
s101: transmitting a signal through a transmitting antenna of the wireless module;
s102: scanning the intensity of sideband noise and/or harmonic signals received by a receiving antenna of the wireless module; sideband noise and harmonic signals are generated by signals transmitted by a transmitting antenna;
referring to fig. 3, after power amplification is performed on a signal transmitted by a transmitting antenna of a wireless module (UE shown in fig. 3), high interference noise such as sideband noise and harmonic signal may be generated, and in the embodiment of the present application, the sideband noise and the harmonic signal (preferably, the harmonic signal does not exceed 3 rd harmonic) generated by the signal transmitted by the transmitting antenna of the wireless module are used as a signal source instead of an external signal generator. And then the connection state of the transmitting antenna and the receiving antenna is judged by analyzing the intensity of the coupling sideband noise and/or harmonic signals of the receiving antenna of the wireless module.
In advance, frequency bands of the receiving frequency ranges corresponding to the frequencies of the sideband noise and the harmonic signal of all the transmitting signals can be listed according to the frequency bands supported by the transmitting antennas, and further, the receiving frequency bands of each receiving antenna under different transmitting signals are listed.
For example, as shown in fig. 4, Tx Band a1 to Tx Band Am represent the frequency Band of the transmission signal a1 to the frequency Band of the transmission signal Am. ANT1 to ANT n denote respective receiving antennas. Band P11 denotes a reception Band of Tx Band a1 and reception antenna ANT1, and Band P1m denotes a reception Band of Tx Band Am and reception antenna ANT 1. By analogy, Band Pn1 denotes the reception Band of the reception antenna ANTn under Tx Band a1, and Band Pnm denotes the reception Band of the reception antenna ANTn under Tx Band Am.
S103: and analyzing the intensity of the sideband noise and/or harmonic signals received by the receiving antenna to obtain the connection state of the transmitting antenna and the receiving antenna.
The method for analyzing the strength of the receiving antenna receiving the sideband noise and/or the harmonic signal to obtain the connection state of the transmitting antenna and the receiving antenna may be as follows:
comparing the intensity of the sideband noise and/or harmonic signal received by the receiving antenna with the corresponding intensity threshold;
and analyzing the comparison result to obtain the connection state of the transmitting antenna and the receiving antenna.
The relative distance between each receiving antenna and each transmitting antenna in the wireless module is different, so that the intensity of sideband noise and harmonic signals coupled to each receiving antenna is different, and a corresponding intensity threshold can be set for the receiving antennas according to the intensity of the sideband noise and the harmonic signals generated by the transmitting signals and the coupling degree between the transmitting antennas and the receiving antennas in advance. The coupling degree between the transmitting antenna and the receiving antenna can be calculated or measured according to the relative position relationship between the antennas.
For example, as shown in fig. 5, the Tx Band a1 lower receiving antenna ANT1 couples sideband noise (edge shown in fig. 5), and the intensity threshold (signal determination threshold shown in fig. 5) is set to T11 dBm. The receiving antenna ANT1 under Tx Band Am couples harmonic signals, and the set strength threshold is T1m dBm.
After the transmitting antenna sends signals, the intensity of the sideband noise and/or harmonic signals received by the receiving antenna is scanned, the intensity of the sideband noise and/or harmonic signals received by the receiving antenna is compared with the corresponding intensity threshold, and then the comparison result is analyzed to obtain the connection state of the transmitting antenna and the receiving antenna.
In some embodiments, the manner of analyzing the comparison result to obtain the connection state of the transmitting antenna is as follows:
and if the intensity of the sideband noise and/or the harmonic signal received by each receiving antenna is less than the corresponding intensity threshold, the connection of the transmitting antenna is abnormal.
If the intensity of the sideband noise and/or harmonic signals received by one or more than one receiving antenna is not less than the corresponding intensity threshold, the transmitting antenna is normally connected.
That is, if the strength of the sideband noise and/or harmonic signals received by all the receiving antennas is less than the corresponding strength threshold, the transmitting antenna is considered to be abnormally connected. And as long as the intensity of the sideband noise and/or harmonic signals received by one receiving antenna is not less than the corresponding intensity threshold, the transmitting antenna is considered to be normally connected.
In some embodiments, the manner of analyzing the comparison result to obtain the connection state of the receiving antenna is as follows:
if the intensity of the sideband noise and/or the harmonic signal received by the receiving antenna is not less than the corresponding intensity threshold, the receiving antenna is normally connected;
and if the intensity of the sideband noise and/or the harmonic signal received by the receiving antenna is less than the corresponding intensity threshold, the receiving antenna is abnormal in connection.
In this embodiment, as long as the strength of the sideband noise and/or the harmonic signal received by the receiving antenna is not less than the corresponding strength threshold, the receiving antenna is considered to be connected normally. Conversely, as long as the intensity of the sideband signal and/or the harmonic signal received by the receiving antenna is less than the corresponding intensity threshold, the receiving antenna is considered to be abnormally connected.
In other embodiments, the manner of analyzing the comparison result to obtain the connection state of the receiving antenna is as follows:
if the intensity of the sideband noise and/or harmonic wave signals received by the receiving antenna is not less than the corresponding intensity threshold, the receiving antenna is normally connected;
and if the intensity of the sideband noise and/or the harmonic signal received by the receiving antenna is smaller than the corresponding intensity threshold and the transmitting antenna is normally connected, the receiving antenna is abnormally connected.
The reason that the strength of the sideband noise and/or harmonic signal received by the receiving antenna is smaller than the corresponding strength threshold may be that the receiving antenna is connected abnormally, and may also be that the transmitting antenna is connected abnormally. In order to more accurately determine the connection state of the receiving antenna, the connection state of the transmitting antenna is considered comprehensively in this embodiment, and under the condition that the connection of the transmitting antenna is normal, if the strength of the receiving antenna for receiving the sideband noise and/or the harmonic signal is not less than the corresponding strength threshold, the connection of the receiving antenna is normal; and if the intensity of the sideband noise and/or the harmonic signal received by the receiving antenna is less than the corresponding intensity threshold, the receiving antenna is abnormally connected.
Example two
On the basis of the above embodiment, the present embodiment further includes, before transmitting a signal through the transmitting antenna of the wireless module:
scanning an environment background noise of a receiving frequency band of a receiving antenna corresponding to a transmitting frequency band of the transmitting antenna;
judging whether the environmental background noise meets a preset condition or not;
if yes, transmitting a signal positioned in a transmitting frequency band through a transmitting antenna;
and if not, adjusting the transmitting frequency band of the transmitting antenna until the environmental background noise of the receiving frequency band of the receiving antenna corresponding to the transmitting frequency band of the transmitting antenna meets a preset condition, and transmitting the signal positioned in the transmitting frequency band through the transmitting antenna.
In order to further improve the accuracy of detection and reduce the influence of the environmental background noise, before the signal is transmitted through the transmitting antenna, the embodiment first determines an appropriate transmitting frequency band by analyzing the environmental background noise of the receiving frequency band. The basis for determining the proper transmitting frequency band is that the environmental background noise of the receiving frequency band satisfies the preset condition, i.e. the above preset condition.
The method for judging whether the environmental background noise meets the preset condition can be as follows:
judging whether the environmental background noise is not greater than the difference value between the corresponding intensity threshold and a preset value or not;
if the environmental background noise is not greater than the preset environmental background noise, the environmental background noise meets preset conditions;
if the environmental background noise is larger than the preset threshold, the environmental background noise does not meet the preset condition.
The size of the preset value can be set according to the situation of the wireless module. For example, the preset value is set to 6, and thus, if the environmental background noise > the corresponding intensity threshold-6, the environmental background noise is considered not to satisfy the preset condition. And if the environmental background noise is less than or equal to the corresponding strength threshold of-6, the environmental background noise is considered to meet the preset condition.
Referring to fig. 6, a flow of detecting a connection state of an antenna may be as follows:
scanning receiving antenna n, n equals 1. The frequency Band of the transmission signal is set to be Band Am, and m is 1. And scanning the environment background noise Gnm of the receiving frequency Band corresponding to the receiving antenna n and the Band A1. And judging whether the environmental background noise Gnm is larger than Tnm-6. Tnm represents the intensity threshold corresponding to the receiving antenna n under Band a 1. If the frequency Band is larger than the preset frequency Band, m is equal to m +1, namely the frequency Band of the transmission signal is adjusted to be Band A2. And then scanning an environment background noise Gnm of a receiving frequency Band corresponding to the receiving antenna n and the Band A1, and judging whether the environment background noise Gnm is more than Tnm-6 or not until the environment background noise Gnm is not more than Tnm-6 or not. When the ambient noise floor Gnm is not greater than Tnm-6, a signal at Band Am is transmitted at this time and the strength of the sideband noise and/or harmonic signals received by the receive antenna n is scanned. And judging whether the intensity of the sideband noise and/or the harmonic signal received by the receiving antenna n is less than the corresponding intensity threshold or not. And if the intensity is smaller than the corresponding intensity threshold, judging that the connection of the receiving antenna n is normal. If not, judging that the connection of the receiving antenna n is abnormal. It is determined whether all the receiving antennas have been scanned. If all the receiving antennas are scanned, the method is finished. If not, n is n +1, and then the frequency Band for setting the transmission signal to be Band Am is returned to be executed, and the subsequent operation is executed.
The foregoing embodiments mainly address the case where the wireless module includes a single transmitting antenna, and for a wireless module including two or more transmitting antennas, cross validation may also be performed to further improve the accuracy of detection.
Specifically, the signal may be transmitted through each transmit antenna sequentially. For each transmitting antenna, the detection scheme described in the above embodiment may be adopted to detect the connection state of the receiving antenna and the transmitting antenna that transmits the signal this time.
For the receiving antenna, the connection state of the receiving antenna can be judged by integrating the strength of the receiving signal of the receiving antenna when different transmitting antennas transmit signals.
For example, when the transmitting antenna 1 transmits a signal, the strength of the receiving antenna 5 for receiving sideband noise and/or harmonic signals is less than the corresponding strength threshold. When the transmitting antenna 2 transmits signals, the strength of the sideband noise and/or harmonic signals received by the receiving antenna 5 is not less than the corresponding strength threshold. In this case, the reception antenna 5 is normally connected. The reason why the strength of the receiving antenna 5 for receiving sideband noise and/or harmonic signals is less than the corresponding strength threshold when the transmitting antenna 1 transmits signals may be because the transmitting antenna 1 is further away from the receiving antenna 5.
For the transmitting antenna, the connection state of the receiving antenna can be determined by integrating the strength of the receiving signal of the receiving antenna when the transmitting antenna transmits the signal.
For example, when the transmitting antenna 1 transmits a signal, the strength of the receiving antenna 2 for receiving sideband noise and/or harmonic signals is less than the corresponding strength threshold. When the transmitting antenna 3 transmits signals, the strength of the receiving antenna 2 for receiving sideband noise and/or harmonic signals is not less than the corresponding strength threshold. In this case, the two cases are combined to consider that the receiving antenna 1 is connected abnormally.
In summary, in the antenna connection detection method provided by the application, the sideband noise and the harmonic signal generated by the signal transmitted by the wireless module replace the external signal generator to serve as the information source, so that the dependence on the external signal generator is removed, and the detection cost is greatly reduced. In addition, once the product is determined, the relative positions (including distance and direction) between the antennas on the product are fixed, the coupling coefficient between the antennas is basically determined, the coupling degree between the antennas cannot be influenced by the movement of the product body, and the test is more accurate. In addition, the transmitted signals of the wireless module are multiple and optional, sideband signals and harmonic signals exist in multiple numbers, namely multiple signal sources exist, and compared with a multi-signal generator scheme, the antenna connection detection method provided by the application can effectively save production space and equipment cost. Different from the situation that a plurality of signal generators simultaneously generate a plurality of signals, the wireless module generates one transmitting signal each time, and the influence on the judgment result caused by the interference of the plurality of transmitting signals can be avoided. By the aid of the detection method, detection can be performed during production, and the antenna can be detected at any time during use.
