A method and apparatus for abnormal recovery of standing wave ratio detection

Abstract

This application relates to a method and apparatus for recovering from VSWR anomalies, belonging to the field of wireless communication. The method performs VSWR detection on a channel, calculating the VSWR value of the channel based on the forward and reverse power detected by the voltage standing wave ratio. It then determines whether the VSWR value exceeds a specified threshold. If the VSWR value exceeds the specified threshold, the channel is determined to be a VSWR-abnormal channel. Simultaneously, the cumulative number of VSWR anomalies for the abnormal channel is recorded, and the abnormal VSWR channel is switched on and off according to a certain strategy to restore the VSWR-abnormal channel. If the VSWR value does not exceed the specified threshold, the cumulative number of VSWR anomalies for the channel is cleared, and the calculated VSWR value is reported. This application's solution can recover from VSWR anomalies in a very short time without reinitializing the system or re-establishing service connections.

Description

Technical Field

[0001] This application belongs to the field of wireless communication, and specifically relates to an anomaly recovery method and apparatus for VSWR detection. Background Technology

[0002] In radio frequency (RF) transmission systems, impedance mismatch between the antenna and the feed line, or between the antenna and the transmitter, can cause high-frequency energy to be reflected and combine with forward interference to generate standing waves (SWRs). To characterize and measure the SWR characteristics in an antenna feedback system—that is, the relationship between the forward and reflected waves in the antenna—the concept of "standing wave ratio" (VSWR) was introduced. The voltage standing wave ratio (VSWR), also known as the standing wave ratio (SWR), reflects the state of the standing wave. A higher VSWR indicates a deterioration in signal transmission performance and a decrease in channel gain; a typical example is a decrease in sensitivity. Therefore, to ensure signal quality, it is necessary to monitor the VSWR of the base station to allow for timely adjustments to parameters such as the transmission line impedance.

[0003] Currently, the main circuit structures for detecting the VSWR at the base station antenna port are as follows: Figure 1 The diagram shows the circuit structure for obtaining the forward and reverse signals from the base station antenna port via a coupler located near the base station antenna port using a duplexer. Forward and reverse power detection are performed sequentially on the transmission line using a switching switch to measure the forward power Pf and reverse power Pr. Then, the values ​​are calculated according to the formula RL(db) = 10log 10 Pf / Pr and VSWR = (10 RL(db) / 20+1) / (10 RL(db) / 20 -1) The VSWR value is calculated, where RL is the return loss. Currently, various VSWR detection and calculation schemes focus on improving detection accuracy, but do not consider recovery mechanisms in case of VSWR anomalies. Traditional VSWR detection methods, when detecting VSWR anomalies, typically involve stopping ongoing services, performing system initialization, and rebuilding services. This method has a significant impact on customers, who will perceive a service interruption. Summary of the Invention

[0041] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0042] Referring to Figure 2 , Figure 2 Figure 2 is a flow chart of an abnormal recovery method of VSWR detection according to an exemplary embodiment of the present application, as shown in Figure 2, the method comprises the following steps. Figure 2

[0043] S1: performing VSWR detection on the channel, and calculating the VSWR value of the channel according to the forward power and reverse power detected by the voltage standing wave ratio;

[0044] S2: judging whether the VSWR value of the channel exceeds a specified threshold value, if the VSWR value exceeds the specified threshold value, judging that the channel is a VSWR abnormal channel, recording the VSWR cumulative abnormal times of the VSWR abnormal channel and entering the channel abnormal processing flow, setting the VSWR abnormal channel recovery identifier according to the channel abnormal processing result; if the VSWR value does not exceed the specified threshold value, clearing the VSWR cumulative abnormal times of the channel, and reporting the calculated VSWR value;

[0045] S3: judging whether to recover the VSWR abnormal channel according to the VSWR abnormal channel recovery identifier, if the VSWR abnormal channel is recovered, reporting the historical VSWR value when the VSWR value of the VSWR abnormal channel is recorded for the first time; if the VSWR abnormal channel is not recovered, performing the next round of VSWR detection process and calculating the VSWR value.

[0046] Further, in an embodiment, the VSWR detection on the channel according to the VSWR detection process, and calculating the VSWR value of the channel according to the forward power and reverse power detected by the voltage standing wave ratio specifically comprises:

[0047] The standing wave ratio detection device performs forward power detection and reverse power detection on the transmission line of the base station coupler in the first preset time period, respectively obtains the forward transmission power, forward receiving power, reverse transmission power and reverse receiving power of the transmission line of the base station coupler;

[0048] ​According to the detected forward transmit power, forward receive power, reverse transmit power and reverse receive power, the VSWR value of the transmission line corresponding channel of the base station coupler is calculated by using the VSWR calculation formula.

[0049] The first preset time period can be set to 10 milliseconds, or can be set according to actual needs.

[0050] Specifically, referring to Figure 1 As shown in the figure, the existing base station antenna port standing wave ratio detection device includes an FPGA chip 1, a digital-to-analog converter 2, a duplexer 3 and a selection switch 4. The device performs forward power detection and reverse power detection on the transmission line in turn through the selection switch, realizes VSWR detection of the transmission line of the coupler 5 at the base station antenna port, and the specific operation process is as follows:

[0051] First, the selection switch is switched to the forward detection mode, and the FPGA chip 1 detects the forward transmit power and the forward receive power, i.e. the forward power, within 10 milliseconds. The value of the forward power is the same as that of the forward transmit power or the forward receive power.

[0052] Secondly, the selection switch is switched to the reverse detection mode, and the FPGA chip 1 detects the reverse transmit power and the reverse receive power, i.e. the reverse power, within 10 milliseconds. The value of the reverse power is the same as that of the reverse transmit power and the reverse receive power.

[0053] Thirdly, the VSWR is calculated according to the detected forward transmit power, forward receive power, reverse transmit power and reverse receive power. The related calculation formula is recorded in the prior art, and can be referred to in the documents such as the standing wave ratio detection method and device disclosed in the Chinese patent with the application number CN200610149605.2 and the standing wave ratio detection method and device disclosed in the Chinese patent with the application number CN00106322.7. The present application scheme will not be described here.

[0054] Finally, it is judged whether the VSWR is abnormal. If the VSWR is abnormal, the abnormal VSWR channel needs to be switched according to a certain strategy, so as to restore the VSWR abnormal channel.

[0055] Further, in one embodiment, the VSWR cumulative abnormal times of the VSWR abnormal channel are recorded and the channel abnormal processing flow is entered, which is specifically:

[0056] When the VSWR value of the channel is detected to be abnormal, the VSWR cumulative abnormal times of the VSWR abnormal channel are recorded, and the VSWR cumulative abnormal times are increased by 1.

[0057] determining whether the VSWR cumulative abnormality number is 1, if the VSWR cumulative abnormality number is 1, recording the current VSWR value as a historical VSWR value and reporting the current VSWR value, if the VSWR cumulative abnormality number is not 1, further determining whether the VSWR cumulative abnormality number is 3;

[0058] if the VSWR cumulative abnormality number is 3, closing the current VSWR abnormal channel, if the VSWR cumulative abnormality number is not 3, reporting the historical VSWR value.

[0059] Further, in one embodiment, the setting of the VSWR abnormal channel recovery identifier according to the channel abnormality processing result specifically comprises:

[0060] if the channel abnormality processing result is closing the current VSWR abnormal channel, setting the VSWR abnormal channel recovery identifier of the VSWR abnormal channel as 1, indicating recovering the VSWR abnormal channel.

[0061] Specifically, referring to Figure 3 The application scheme is described in detail through a preferred embodiment, and the specific technical implementation process is as follows:

[0062] The VSWR detection is periodically performed with 1 minute as a period.

[0063] The VSWR channel reopening function is determined to be performed according to the VSWR abnormal channel opening identifier. The VSWR abnormal channel opening identifier refers to when VSWR abnormality of a channel is detected for three times continuously, the channel is closed, and the identifier is set as 1, so as to determine whether the channel recovery (opening) function is performed when the next VSWR detection starts. If the channel needs to be opened, the VSWR value reported this time is the historical value recorded when the channel is first abnormal, because the channel is closed at this time, and the VSWR calculation is necessarily abnormal.

[0064] If the abnormal channel opening operation does not need to be performed, the normal VSWR detection and calculation process is entered. First, the FPGA chip 1 controls the selection switch (feedback switch) to switch to the forward detection mode, the FPGA chip 1 detects the forward transmission power and the forward receiving power within 10 milliseconds, and stores the detected values in the FPGA chip 1 internal register; second, the FPGA chip 1 controls the selection switch (feedback switch) to switch to the reverse detection mode, the FPGA chip 1 detects the reverse transmission power and the reverse receiving power within 10 milliseconds, and stores the detected values in the FPGA chip internal register. The forward transmission power, the forward receiving power, the reverse transmission power and the reverse receiving power are read from the FPGA chip register. The real-time VSWR value of this time is calculated and obtained according to the parameters.

[0065] It is judged whether the VSWR value this time exceeds the specified threshold. If it does not exceed the threshold, the abnormal accumulation number caused by the possible historical VSWR abnormality needs to be cleared. If it exceeds the threshold, it is considered that the VSWR value this time is abnormal, and the abnormal processing flow needs to be entered in order to restore the channel of the VSWR abnormality subsequently. In the abnormal processing flow, the abnormal accumulation number needs to be added by 1.

[0066] It is judged whether the abnormal accumulation number is 1. If it is 1, it indicates that it is the first time to enter the VSWR abnormality, and the current abnormal VSWR value needs to be recorded for subsequent reporting.

[0067] It is judged whether the abnormal accumulation number is 3. If it is 3, it indicates that the VSWR channel has been abnormal for 3 times in succession, which triggers the condition that the channel needs to be closed, so the channel needs to be closed, and the VSWR abnormal channel opening identifier is set in order to open the channel according to the identifier when the VSWR is calculated next time.

[0068] After the next VSWR detection starts, if it is found that the VSWR abnormal channel opening identifier is set, the channel will be opened according to the identifier, and the VSWR detection can be restored to normal after the channel is opened.

[0069] The method provided in the application can restore the VSWR abnormality in a very short time without reinitializing the system and reestablishing the service connection when the VSWR is abnormal, and has high potential commercial value.
