Embodiment
In order to make technical problem to be solved by this invention, technical scheme and beneficial effect clearer, clear,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The embodiment of the invention provides a kind of standing-wave ratio alarm detection method, realizes that based on base station antenna feeder standing wave technology this method flow is as shown in Figure 1, comprises the steps:
Step S101: receive the antenna feeder EM equipment module AEM emission path warning information that reports.
Detect to standing-wave ratio alarm, traditional mode is when there is standing-wave ratio alarm in AEM emission path, report and alarm information, promptly passive detection AEM standing-wave ratio alarm.
With global system for mobile communications (Global System of Mobile communication; GSM) in the emission path of AEM being carried out standing-wave ratio alarm detects and is example; Detect each GSM time slot A EM emission path whether alarm is arranged; Do not consider to launch path and whether transmitting power output, passive detection that Here it is are arranged at each GSM time slot.
Step S102: when receiving the AEM emission path warning information that reports; The AEM that initiatively relates to the warning information that reports sends at least one transmission channel (Traffic Channel, TCH) detection signal of carrier frequency that continues setting-up time length with particular transmission power.
After receiving the AEM warning information that reports; After being the passive AEM of detecting standing-wave ratio alarm; Requirement is carried out active detecting to the AEM that relates to, to detection signal and the lasting emission setting-up time length of the AEM that relates to at least one TCH carrier frequency of particular transmission power emission.The emission path of the AEM that guarantees to detect has transmitting power output.
For example: when detecting certain GSM time slot and have the AEM standing-wave ratio alarm, send the detection signal of some or several carrier frequency to this AEM with setting-up time length and particular transmission power.In the setting-up time length of emitting detection signal, detect this AEM once more and whether have standing-wave ratio alarm at certain GSM time slot, the process of active detecting that Here it is.
Wherein, particular transmission power can accurately detect the transmitting power scope setting that alarm exists when detecting according to standing-wave ratio alarm; The TCH carrier frequency is selected according to the principle that the carrier frequency with adjacent AEM does not disturb.Timeslot number that transmitting power is arranged and the timeslot number setting that detects standing-wave ratio alarm that emitting detection signal sets time span is required according to active detecting.
Therefore, specific transmitting power is meant that the carrier frequency power during the active detecting can not produce interference to network or the carrier frequency that closes on.Simultaneously guarantee that again transmitting power can reach the accurate thresholding that detects standing-wave ratio alarm.Setting-up time length is meant that the time of active detecting timeslot number that can guarantee transmitting power and the timeslot number that detects standing-wave ratio alarm reaches the threshold value of setting.Time can not be oversize simultaneously, in order to avoid influence the operate as normal of carrier frequency.
Step S103: in setting-up time length, whether the AEM that the warning information that reports through the detection signal detection of launching relates to exists the alarm of emission path.
To the detection signal of each TCH carrier frequency, confirm the ratio of transmitting power and the reflection power of the AEM that said warning information relates to, relatively the size of the alarm threshold of this ratio and setting confirms whether the AEM that warning information relates to exists the alarm of emission path.
This step determines whether to exist the alarm of emission path according to the detection signal of emission, judges promptly whether the testing result of active detecting is consistent with the testing result of passive detection.
In this step, for the base station that no physics backboard between carrier frequency and the carrier frequency connects, promptly spatially be separate between carrier frequency and the carrier frequency, then the active detecting result with single carrier frequency is as the criterion.Promptly only need the detection signal of a carrier frequency of transmission particular transmission power to get final product.
The GSM base station of a plurality of AEM and carrier frequency is installed for traditional same one deck simultaneously; In active detecting constantly; Requirement is all launched the detection signal of setting-up time length with each carrier frequency of one deck with specific transmitting power, in this setting-up time length, through the identical backboard of this layer; Read alarm signal, and report with all AEM standing-wave ratio alarm of layer.When same AEM being detected same alarm, confirm that just there is alarm in this AEM with all carrier frequency of layer.The bad mistake alarm that causes of the detection path of getting rid of certain carrier frequency like this.
When the detection signal of more than carrier frequency of emission particular transmission power; Its principle is as shown in Figure 2; Having the base station of 3 AEM and 3 carrier frequency to carry out the detection of AEM standing-wave ratio alarm with one with one deck is example; As can beappreciated from fig. 2, three AEM are designated AEM0, AEM1 and AEM2, and three carrier frequency are designated carrier frequency 1, carrier frequency 2 and carrier frequency 3.3 carrier frequency with one deck can detect each AEM through backboard.When passive when detecting standing-wave ratio alarm; For example AEM0 alarm, in order to confirm the accuracy of AEM0 standing-wave ratio alarm, each carrier frequency all can carry out active detecting; The detection signal of launching the time span of setting with specific transmitting power detects the AEM0 that has reported standing-wave ratio alarm information; Adjudicate according to the result after 3 carrier frequency active detecting then, judge whether 3 carrier frequency all are to have standing-wave ratio alarm to the testing result of the AEM that reported standing-wave ratio alarm information, if words; Then report the AEM0 standing-wave ratio alarm; Otherwise only report a notice to get final product,, guarantee carrier frequency hardware operate as normal so that the prompting network maintenance staff need carry out hardware check to all carrier frequency of this layer.Alarm for AEM1 and AEM2 also is similar processing.
How there is alarm in the emitting detection signal with judging whether for controlling, and then uses the correlation technique of prior art to realize.For example, can use standing-wave ratio alarm testing circuit of the prior art to carry out standing-wave ratio alarm and detect, use timer to control the power of the emission path emission special time of carrier frequency.
Step S104: according to testing result, the detection signal corresponding detection result that judges whether each TCH carrier frequency shows that all there is the alarm of emission path in the AEM that the warning information that reports relates to.
This step judges that the result of each TCH carrier frequency active detecting is whether consistent, when unanimity, reports the AEM standing-wave ratio alarm, inconsistently then only reports a notice.
If, promptly when the detection signal corresponding detection result of each TCH carrier frequency shows that all there is the alarm of emission path in AEM that warning information relates to, execution in step S105, otherwise execution in step S106.
The transmitting power of the AEM module that the warning information that obtains when the particular transmission power detection of each TCH carrier frequency relates to and the ratio of reflection power think that the detection signal corresponding detection result of each TCH carrier frequency shows that all there is the alarm of emission path in the AEM that warning information relates to during all less than the alarm threshold set.
Step S105: there is the alarm of emission path in the AEM that the warning information of confirming to report relates to.
When step S105 is judged as when being; The transmitting power that promptly detects the AEM that the warning information that obtains relates to when the said TCH carrier frequency of each of particular transmission power and the ratio of reflection power confirm that the AEM that warning information relates to exists the emission path to alarm during all less than the alarm threshold set.
Step S106: there is not the alarm of emission path in the AEM that the warning information of confirming to report relates to.
When step S105 is judged as not; When the transmitting power of the AEM that the warning information that promptly obtains as the detection of the TCH of at least one particular transmission power carrier frequency relates to and the ratio of reflection power are not less than the alarm threshold of setting, confirm that there is not the alarm of emission path in the AEM that said warning information relates to.
When said method reports some AEM standing-wave ratio alarms as carrier frequency; Initiatively initiate testing process; Again detect related AEM whether standing-wave ratio alarm is really arranged; Because the detection signal that particular transmit frequency arranged transmits as AEM's, the mistake alarm of avoiding false dismissal that the TCH carrier frequency power causes for a short time and antenna interference to cause.
