Embodiment
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
Fig. 1 schematically shows the structure of the micro power radio communication error rate detection analyzer of one embodiment of the present invention.
As shown in Figure 1, when carrying out error rate analyzer to equipment under test 6 and detecting, can according to the type of coding to be detected of equipment under test 6 (such as AIS code, 1000 yards, PN9 pseudo noise code etc.), programming Control is carried out to data processing unit 1, data processing unit 1 is according to programming Control, encode out and meet the coding to be detected of equipment under test 6 reception, and by clock detection module (PWM controller 2), the serial/parallel line output interface 5 by data processing unit 1 after code conversion to be detected is transferred to equipment under test 6, equipment under test 6 receives code signal to be detected and responds, and response signal is transferred to data processing unit 1 by the serial/parallel row input interface 4 of data processing unit 1, data processing unit 1 carries out time-ordered measurement by controlling clock detection module (PWM controller 2) to the response signal fed back, the receivable waveform signal of data processing unit 1 is met to capture, and after waveform signal is transformed, data processing unit 1 is transferred to by clock synchronous interface 8, data processing unit 1 is added up the waveform signal received, and to compare statistical analysis with previous output encoder, finally, draw the error rate of equipment under test.
Data processing unit 1 and clock detection module (PWM controller 2) can carry out input/output control under following two kinds of patterns:
Under real-time analysis pattern, data processing unit 1 pair of pseudo-random number sequence and fixing ordered series of numbers are encoded, coding immediately exports to equipment under test 6 after clock detection module (PWM controller 2) transforms, simultaneously, clock detection module (PWM controller 2) immediately can capture the decoding of exterior trajectory measurement equipment 6 and feed back to data processing unit 1 and namely go out the Data Stream Processing namely entered and real time contrast analyzes, and draws error code quantity and the error rate.Pseudo-random number sequence has good randomness and the correlation function close to white noise, and there are confirmability in advance and repeatability, make dependence test have the advantage of objectivity (preventing equipment under test to be optimized for certain sequence), trackability (can compare the consistency of Code And Decode).Under statistical analysis pattern, can add up except error code quantity and the error rate as Parameter analysis such as signal strength signal intensity, demodulation sensitivity, coding qualities, result is stored in the inner integrated buffer area of data processing unit 1 extract display for external equipment (PC 7) or carry out secondary analysis, also quadratic programming is done to data processing unit 1, to carry out protocol conformance analysis by external equipment (PC 7).
Be specially, the api interface that user provides by PC 7 is connected with the control interface 3 of data processing unit 1, re-encoding is carried out to the test data stream that data processing unit 1 buffering area stores, simultaneously for different demands, the test environments such as setting Test code speed, to adapt to different equipment under test tests.
In addition, user also can by adding agreement at coding, under use control interface 3 opens the prerequisite of protocol conformance analytic function, the protocol conformance of coding being carried out to " exporting data A-> reply data B-> data to compare " type compares.By said process, can realize again programming for the test of dissimilar equipment under test, and be not limited to default several test modes, also can to the response of device protocol data, to check out the data processing defect of equipment.
Data processing unit 1 provides serial/parallel row input interface 4 and serial/parallel line output interface 5, and equipment under test can by the serial/parallel row input interface 4 of connection and reception and the feedback of carrying out data between serial/parallel line output interface 5 and data processing unit 1; In addition, can support that serial newly developed and parallel communication protocols process respectively by serial and parallel interface by setting.
In addition, data processing unit 1 additionally provides control interface 3, control interface 3 (can be serial ports, USB port, network interface etc.) realizes man-machine interaction by PC, detects analytical equipment carry out the multiple settings such as display configuration, test interface configuration, test pattern configuration, test data download, test process program downloads and carry out real-time, interactive and analysis to data result this micro power radio communication error rate; In addition, new test function is added by firmware upgrade.

As shown in Figure 2, detect the error rate during transmission signal analyzing equipment under test 6, equipment under test 6 is by the output of the output interface access data processing unit 1 of testing equipment, data processing unit 1 carries out in-line coding, then coding is exported, equipment under test 6 receives the coding exported, and coding is modulated, now, equipment under test is as data transmitting terminal, data after modulation are sent, because data processing unit 1 can only by wired mode receipt decoding, need by accompanying the special demodulating equipment of measurement equipment 6'(through calibrating) as data receiver, demodulation is carried out to the modulation signal that equipment under test 6 sends, accompany measurement equipment 6' that the data after demodulation and decoded data are transferred to data processing unit 1 by the input interface of testing equipment, complete the error rate analyzer of the transmission signal to equipment under test 6, and analysis result is shown by PC 7.
Embodiment 2
As shown in Figure 3, detect the error rate during Received signal strength analyzing equipment under test 6, equipment under test 6 is by the input of the input interface access data processing unit 1 of testing equipment, data processing unit 1 is encoded in inside, then coding is outputted to and accompanies the dedicated modulation equipment of measurement equipment 6'(through calibrating) modulate, now accompany measurement equipment 6' as data transmitting terminal, modulation signal is sent to equipment under test 6, equipment under test is as data receiver, modulation signal is carried out demodulation, and decode information transmission is returned data processing unit, complete the error rate analyzer of the Received signal strength to equipment under test 6, and analysis result is shown by PC 7.
Because equipment under test signal processing exists time delay in the test process of embodiment 1 and 2, therefore need to carry out code stream synchronous, two kinds of code stream methods of synchronization can be adopted: 1. in serial protocol test process, serial communication, as during without sync cap, can use the mode implementation data of protocol data interpolation synchronizing frame head synchronous; 2., in serial protocol test process, when serial communication is as possessed sync cap, the clock synchronous interface 8 that synchronised clock can be connected to data processing unit 1 carries out data syn-chronization.
Embodiment 3
As shown in Figure 4, protocol conformance analysis is carried out to equipment under test 6, first, PC 7 pairs of data processing units 1 carry out quadratic programming, and agreement is write in coding, data processing unit 1 carries out protocol code in inside, now, equipment under test 6 to be decoded to protocol code as the receiving terminal of data and is responded protocol contents, again to response contents carry out agreement again coded transmission to data processing unit 1, data processing unit 1 carries out protocol-decoding and contrast in inside, completes the protocol conformance analysis to equipment under test 6.In addition, in parallel protocol test process, synchronised clock should be used to carry out data syn-chronization, to increase the accuracy of detection.In the present embodiment, equipment under test 6 does not limit the system in combination with single device or multiple devices.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
