The detecting unit with transmission-receiving function that the present invention is set can have following two kinds of situations:
1), can directly adopt in the smart antenna one in the existing transceiver as described detecting unit for the consideration of cost.
In this case, need to increase the state that corresponding logical circuit is controlled this detecting unit.For example: can be provided with one and be used for diverter switch that this detecting unit is switched between detected state and operating state;
Detection for the transceiver transmit status:
Described diverter switch triggers in all transceivers one as described detecting unit, and the described coupled signal that is received from described coupler is sent to described judging unit;
Detection for the transceiver accepting state:
Described diverter switch triggers in all transceivers one as described detecting unit, sends described default test signal to described coupler;
Except that above-mentioned two kinds of situations, described diverter switch triggers this transceiver and carries out common transmission-receiving function as general transceiver, and at this moment, this transceiver is worked normally as the general transceiver in the smart antenna.
2) for the clear and definite consideration of the division of labor, can in system, additionally increase by one and be exclusively used in the transceiver that carries out detection of the present invention.
Because in the practical application, the reason of transceiver working state abnormal has multiple, for example, might be that certain transceiver damages, cause the default test signal of this transceiver transmission or the coupled signal of reception to detect less than tangible peak value; The link gain that also might be certain transceiver has problem, causes the coupled signal of default test signal that this transceiver sends or reception little more a lot of than the intensity of the default test signal of numeric field.At the multiple situation that may occur in the practical application, can on the basis of technique scheme, second difference threshold, the 3rd difference threshold etc. be set, so that the various situations that may occur are carried out corresponding judgment.For example, at the problem of link gain:
Described judging unit is after the transmit status of judging certain transceiver or accepting state are undesired, can also be used for more described default test signal and the difference between the coupled signal after the coupling circuit transmission and the size of described second difference threshold before the coupling circuit transmission, and in described difference smaller or equal to described second difference threshold, judge that the link gain of respective transceivers is undesired.
In actual applications, can cause the reason of transceiver working state abnormal that corresponding thresholding is set at other, described reason is judged with reference to above-mentioned example.
As previously mentioned, the detecting unit with transmission-receiving function of setting of the present invention can be in the existing transceiver in the smart antenna, also can be that extra of increasing is exclusively used in the transceiver that carries out detection of the present invention.Below by two embodiment, described two kinds of situations are described respectively.
Easy for describing, in the following embodiments, the transceiver in the smart antenna is called the work transceiver.
Embodiment one:
Present embodiment is an example with one six antenna TD-SCDMA system, illustrates how to adopt to be exclusively used in the detecting unit realization the present invention who detects.
Fig. 3 is in the embodiment of the invention one being applied to on-line measuring device the composition structural representation of TD-SCDMA system.Referring to Fig. 3, this system comprises: the detecting unit of 6 work transceivers (that is: transceiver 0～5) as shown in the figure and 1 special use constitutes coupling circuit by the antenna coupling disc between the detecting unit of this 1 special use and 6 work transceivers.The operation principle of this system is:
When system was in normal operating conditions, this special-purpose detecting unit was in holding state, does not send or receive any signal;
When the moment of the transmit status of measuring transceiver arrives (for example :) at the GP time slot, that is: when system is in each transceiver transmit status of detection, the default test signal that sends from numeric field is converted to radiofrequency signal through each transceiver and sends to antenna opening, described radiofrequency signal enters this special-purpose detecting unit through coupling disc, this special-purpose detecting unit sends to judging unit with the radiofrequency signal that receives, judging unit is transformed into numeric field with described radiofrequency signal, obtain the intensity that each transceiver sends default test signal, and whether judge the transmit status of respective transceivers by the amplitude size that sends signal normal;
When the moment of the accepting state of measuring transceiver arrives, that is: when system is in each transceiver accepting state of detection, testing process is identical with the process that detects transmit status, uniquely different be: send default test signal by transceiver, 6 work transceivers will be preset test signal and receive and send to judging unit, be transformed into numeric field by judging unit and calculate and judge.
Fig. 4 shows in the embodiment of the invention one result schematic diagram that the transmit status to the work transceiver detects.Transmit status for each transceiver detects, and in fact is exactly that tested transceiver sends default test signal, and detecting unit receives the test signal through overcoupling, gives judging unit and calculates.By allowing each transceiver send different default test signals, can make judging unit that the peak point that the coupled signal of each transceiver calculates is appeared at the different position of cycle tests, and can not interfere with each other each other, so just can measure the transmit status of a plurality of branch roads simultaneously.Referring to Fig. 4, it is the simultaneously-measured result of calculation of each transceiver, and the X-axis among the figure is represented the position of cycle tests, and Y-axis is represented the amplitude difference between the intensity of the intensity of the coupled signal that detecting unit receives and original preset test signal.Among Fig. 4, the X-axis coordinate is 2,6,10,14,18 and 22 the stain original strength of transmitted signals of corresponding transceiver 0～5 shown in Figure 3 respectively, the amplitude of the signal that the Y-axis coordinate representation detecting unit of corresponding stain receives and the amplitude difference between the original strength of transmitted signals, as seen from Figure 4, the amplitude difference of each work transceiver correspondence all is no more than ± 1dB, can judge that thus the transmit status of 6 work transceivers is all normal.
Fig. 5 shows in the embodiment of the invention one another result schematic diagram that the transmit status to the work transceiver detects.Referring to Fig. 5, the X-axis among the figure is represented the position of cycle tests, and Y-axis is represented the amplitude difference between the intensity of the intensity of the coupled signal that detecting unit receives and original preset test signal.Among Fig. 5, the X-axis coordinate is 2,6,10,14,18 and 22 the stain original strength of transmitted signals of corresponding transceiver 0～5 shown in Figure 3 respectively, the amplitude of the signal that the Y-axis coordinate representation detecting unit of corresponding stain receives and the amplitude difference between the original strength of transmitted signals.As can be seen from Figure 5: the signal amplitude difference of work transceiver 1 is-8.063, than the amplitude of original transmission signal little about 8dB, the link gain that this transmission transceiver is described has problem, and the point of work transceiver 3 correspondences be can't see tangible peak value, illustrates that this transceiver may damage.
Embodiment two:

Fig. 6 is in the embodiment of the invention two being applied to on-line measuring device the composition structural representation of TD-SCDMA system.Referring to Fig. 6, this system comprises 6 work transceivers.Because the TD-SCDMA system is TDD system and transmit-receive cofrequency, therefore, can use any one work transceiver, as: work transceiver 0, replace the dedicated test unit among the embodiment one, when detecting, use as detecting unit.In the present embodiment, use coupling disc in the smart antenna as coupling circuit, and by the diverter switch switching of transceiver 0 as operate as normal transceiver and detecting unit of finishing the work.The operation principle of this system is:
When system was in normal operating conditions, work transceiver 0 was connected to by diverter switch on the antenna opening of coupling disc, and this moment, six transceivers were operating state;
When the moment of the transmit status of measuring transceiver arrives (for example :) at the GP time slot, that is: when system is in each transceiver transmit status of detection, to the work reception sender of transceiver 0 of diverter switch switches to the coupling aperture of coupling disc, the receiving branch of transceiver 0 of working this moment becomes detecting unit, each transceiver feeds back by detecting unit in the default test signal that the GP time slot sends, and carry out corresponding conversion at numeric field by judging unit, finish the state that sends transceiver is judged;
When the moment of the accepting state of measuring transceiver arrives, that is: when system is in each transceiver accepting state of detection, diverter switch switches to the coupling aperture of coupling disc at will the work transmitting branch of transceiver 0 of GP time slot, the transmitting branch of transceiver 0 of working this moment becomes detecting unit, and in the default test signal of GP time slot transmission, the receiving branch of each transceiver then feeds back test data at the GP time slot, and carries out corresponding conversion at numeric field, finishes the state of receiving branch is judged.
The detection of accepting state is that detecting unit sends, receiving branch receives, and the receiving branch in 6 transceivers can carry out simultaneously; The detection of transmit status is that the transmitting branch of transceiver sends, and detecting unit receives, and can send different data by each transmitting branch here, and the characteristic of utilizing sign indicating number to divide is once finished the detection to 6 transceivers.
As seen from the above technical solution, the device and method that a plurality of transceivers of smart antenna is carried out online detection provided by the invention, the detecting unit that has transmission-receiving function by setting, and be used to judge whether normal judging unit of the transmit status of transceiver and/or accepting state, and coupling device is set in the antenna opening of smart antenna, make and to form coupling circuit by described coupling device between each transceiver and the detecting unit, so, just can between each transceiver and detecting unit, transmit default test signal by described coupling circuit, and by described judging unit according to default test signal before the transmission of described coupling circuit and the difference between the coupled signal after described coupling circuit transmits, and first difference threshold that sets in advance judges whether the operating state of respective transceivers is normal, thereby reaches whether normal purpose of the online transmission-receiving function of judging each transceiver.
