The signal generator is configured to output a signal of a frequency supported by the wireless module and set an output power. The wireless module reads the signal intensity of a frequency band channel covering the frequency supported by the wireless module; wherein each antenna is read once and a threshold value is set for the signal strength of each antenna.

Detailed Description
The core of the application is to provide an antenna connection detection method, which can reduce the detection cost and improve the detection accuracy. Another core of the present application is to provide an antenna connection detecting apparatus, a device, and a computer-readable storage medium, which all have the above technical effects.
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Example 1
Referring to fig. 2, fig. 2 is a 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 signals 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;
in combination with fig. 3, after power amplification, the signal transmitted by the transmitting antenna of the wireless module (UE shown in fig. 3) generates higher sideband noise, harmonic signal and other interference noise, and in the embodiment of the present application, the external signal generator is replaced by 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. And further, the connection state of the transmitting antenna and the receiving antenna is judged by analyzing the strength of the receiving antenna coupling sideband noise and/or harmonic signals of the wireless module.
The frequency ranges of the receiving frequency ranges corresponding to the sideband noise of all the transmitting signals and the frequency of the harmonic signals can be listed in advance according to the frequency ranges supported by the transmitting antennas, and the receiving frequency ranges of each receiving antenna under different transmitting signals are further listed.
For example, as shown in fig. 4, tx Band A1 to Tx Band Am represent transmission signal A1 frequency Band to transmission signal Am frequency Band. ANT1 to ANTn denote respective receiving antennas. Band P11 represents the reception Band of the reception antenna ANT1 under Tx Band A1, and Band P1m represents the reception Band of the reception antenna ANT1 under Tx Band Am. Similarly, band Pn1 represents the reception Band of the reception antenna ANTn under Tx Band A1, and Band Pnm represents the reception Band of the reception antenna ANTn under Tx Band Am.
S103: and analyzing the strength 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 for receiving sideband noise and/or harmonic signals to obtain the connection state of the transmitting antenna and the receiving antenna may be as follows:
comparing the intensity of sideband noise and/or harmonic signals received by a receiving antenna with the corresponding intensity threshold;
and analyzing and comparing the results to obtain the connection state of the transmitting antenna and the receiving antenna.
The relative distances between each receiving antenna and the transmitting antenna in the wireless module are different, so that the strength of the sideband noise and the harmonic signal coupled to each receiving antenna is different in the same way, and the corresponding strength threshold can be set for the receiving antennas according to the strength of the sideband noise and the harmonic signal generated by the transmitting signal and the coupling degree between the transmitting antenna and the receiving antenna in advance. The coupling degree between the transmitting antenna and the receiving antenna can be calculated or measured according to the relative position relation between the antennas.
For example, as shown in fig. 5, the receiving antenna ANT1 under Tx Band A1 couples sideband noise (edge shown in fig. 5), and the set intensity threshold (signal decision threshold shown in fig. 5) is T11dBm. The receiving antenna ANT1 under Tx Band Am couples the harmonic signal, and the set intensity threshold is T1m dBm.
After the transmitting antenna transmits signals, the strength of the receiving antenna for receiving sideband noise and/or harmonic signals is scanned, the strength of the receiving antenna for receiving sideband noise and/or harmonic signals is compared with a corresponding strength 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 way to analyze the comparison results to obtain the connection state of the transmitting antenna is:
if the intensity of each receiving antenna for receiving sideband noise and/or harmonic signals is smaller than the corresponding intensity threshold, the transmitting antenna is abnormally connected.
If the intensity of the sideband noise and/or the harmonic signal received by one or more receiving antennas is not smaller than the corresponding intensity threshold, the transmitting antennas are connected normally.
That is, if the strengths of all the receiving antennas receiving sideband noise and/or harmonic signals are less than the corresponding strength threshold, the transmitting antenna connection is considered abnormal. As long as the intensity of sideband noise and/or harmonic signals received by one receiving antenna is not smaller than the corresponding intensity threshold, the transmitting antenna is considered to be connected normally.
In some embodiments, the manner in which the comparison result is analyzed to obtain the connection state of the receiving antenna is:
if the strength of the sideband noise and/or the harmonic signal received by the receiving antenna is not smaller than the corresponding strength threshold, the receiving antenna is normally connected;
if the strength of the sideband noise and/or the harmonic signal received by the receiving antenna is smaller than the corresponding strength threshold, the connection of the receiving antenna is abnormal.
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, a receiving antenna is considered to be connected abnormally as long as the strength of the receiving antenna receiving the sideband signal and/or the harmonic signal is less than the corresponding strength threshold.
In other embodiments, the manner in which the comparison result is analyzed to obtain the connection state of the receiving antenna is:
if the strength of the sideband noise and/or the harmonic signal received by the receiving antenna is not smaller than the corresponding strength threshold, the receiving antenna is normally connected;
If the strength of the sideband noise and/or the harmonic signal received by the receiving antenna is smaller than the corresponding strength threshold, and the transmitting antenna is normally connected, the receiving antenna is abnormally connected.
The reason for the strength of the sideband noise and/or the harmonic signal received by the receiving antenna being less than the corresponding strength threshold may be that the receiving antenna itself is connected abnormally, or that the transmitting antenna is connected abnormally. In order to more accurately determine the connection state of the receiving antenna, the embodiment comprehensively considers the connection state of the transmitting antenna, and if the strength of the receiving antenna for receiving sideband noise and/or harmonic signals is not less than the corresponding strength threshold under the condition that the transmitting antenna is normally connected, the receiving antenna is normally connected; if the strength of the sideband noise and/or the harmonic signal received by the receiving antenna is smaller than the corresponding strength threshold, the connection of the receiving antenna is abnormal.
Example two
On the basis of the above embodiment, the present embodiment further includes, before transmitting the signal through the transmitting antenna of the wireless module:
Scanning the environmental background noise of the receiving frequency band of the receiving antenna corresponding to the transmitting frequency band of the transmitting antenna;
judging whether the environmental background noise meets the preset condition;
if yes, transmitting signals in a transmitting frequency band through a transmitting antenna;
If the environmental background noise of the receiving frequency band of the receiving antenna corresponding to the transmitting frequency band of the transmitting antenna meets the preset condition, transmitting a signal positioned in the transmitting frequency band through the transmitting antenna.
In order to further improve the detection accuracy and reduce the influence of environmental noise, before a signal is transmitted through a transmitting antenna, the embodiment first determines a suitable transmitting frequency band by analyzing the environmental noise of the receiving frequency band. The basis for determining the appropriate transmitting frequency band is that the environmental background noise of the receiving frequency band meets the preset condition, namely the 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 larger than the difference value between the corresponding intensity threshold and the preset value;
if the environmental background noise is not larger than the preset condition, the environmental background noise meets the preset condition;
if the environmental background noise is larger than the preset condition, the environmental background noise does not meet the preset condition.
The magnitude of the preset value can be set differently according to the situation of the wireless module. For example, the preset value is set to 6, whereby if the environmental background noise > corresponds to the 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 intensity threshold-6, the environmental background noise is considered to meet the preset condition.
Referring to fig. 6, the flow of detecting the connection state of the antenna may be as follows:
Scanning the receiving antennas n, n=1. The frequency Band of the transmission signal is set to Band Am, m=1. The environmental noise floor Gnm of the reception Band of the reception antenna n corresponding to Band A1 is scanned. 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 A1. If the signal is greater than m=m+1, namely, the frequency Band of the transmitted signal is adjusted to be Band A2. Then, the environmental background noise Gnm of the receiving antenna n and the receiving frequency Band corresponding to Band A1 is scanned, and whether the environmental background noise Gnm is larger than Tmm-6 is judged until the environmental background noise Gnm is not larger than Tmm-6. 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 signal received by the receiving antenna n is scanned. And judging whether the strength of the sideband noise and/or the harmonic signal received by the receiving antenna n is smaller than a corresponding strength threshold. If the received signal is smaller than the corresponding intensity threshold, the receiving antenna n is judged to be connected normally. If not, it is determined that the connection of the receiving antenna n is abnormal. It is determined whether scanning is completed for all the receive antennas. If all the receiving antennas are scanned, the scanning is finished. If not, n=n+1, and then, the setting of the frequency Band of the transmission signal to Band Am, m=1 and the subsequent operations are performed again.
The above embodiments are mainly directed to the case that the wireless module includes a single transmitting antenna, and for the wireless module including two or more transmitting antennas, cross verification may be performed to further improve the accuracy of detection.
In particular, signals may be transmitted sequentially through each transmit antenna. For each transmitting antenna, the connection state of the receiving antenna and the transmitting antenna transmitting the signal can be detected by adopting the detection scheme as described in the above embodiment.
When the receiving antenna is used for transmitting signals, the strength of the receiving antenna for receiving signals can be integrated, and the connection state of the receiving antenna can be judged.
For example, when the transmitting antenna 1 transmits a signal, the strength of the receiving antenna 5 receiving sideband noise and/or harmonic signals is smaller than the corresponding strength threshold. The intensity of the sideband noise and/or the harmonic signal received by the receiving antenna 5 is not less than the corresponding intensity threshold when the transmitting antenna 2 transmits a signal. In this case, the receiving antenna 5 can be considered to be connected normally. The reason why the strength of the sideband noise and/or the harmonic signal received by the receiving antenna 5 is smaller than the corresponding strength threshold when the transmitting antenna 1 transmits a signal is probably due to the fact that the transmitting antenna 1 is far from the receiving antenna 5.
For the transmitting antenna, the strength of the receiving antenna receiving the signal can be judged when the transmitting antenna transmits the signal by combining different transmitting antennas.
For example, when the transmitting antenna 1 transmits a signal, the strength of the receiving antenna 2 receiving sideband noise and/or harmonic signals is smaller than the corresponding strength threshold. The intensity of the sideband noise and/or the harmonic signal received by the receiving antenna 2 is not less than the corresponding intensity threshold when the transmitting antenna 3 transmits a signal. In this case, the connection of the receiving antenna 1 can be considered abnormal.
In summary, in the antenna connection detection method provided by the application, sideband noise and harmonic signals generated by signals emitted by the wireless module are used as information sources instead of the external signal generator, so that dependence on the external signal generator is eliminated, and the detection cost is greatly reduced. In addition, once the product is determined, the relative positions (including the distance and the azimuth) between the antennas on the product are fixed, the coupling coefficient between the antennas is basically determined, the coupling degree between the antennas is not influenced by the movement of the product body, and the test is more accurate. In addition, the wireless module has a plurality of selectable transmitting signals, and a plurality of sideband signals and harmonic signals exist, namely a plurality of information sources. Different from the simultaneous generation of a plurality of signals by a plurality of signal generators, the wireless module generates a transmitting signal at each time, so that the influence of interference of the plurality of transmitting signals on a judging result can be avoided. The detection method provided by the application can be used for detecting not only during production, but also during use, the antenna can be detected at a time.
