Fig. 2 is the structure chart of the switch unit of a kind of radio communication Auto-Test System of the present utility model;
Fig. 3 is the control circuit figure of the control unit of a kind of radio communication Auto-Test System of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the embodiment of utility model is described further.Following examples only are used for explanation the utility model, but are not used for limiting scope of the present utility model.
A kind of radio communication detecting system as shown in Figure 1 comprises test instrumentation, the switch unit that is connected with test instrumentation and the control unit that is connected with switch unit; Test instrumentation is mainly used in testing the parameters of the radio communications such as the bluetooth, WIFI of equipment under test; Switch unit connects a plurality of equipment under tests, and equipment under test can be PAD, panel computer, smart mobile phone etc.; Switch unit has a plurality of passages, the corresponding equipment under test of each passage, after test instrumentation is completed an equipment under test, control unit is controlled switch unit and is switched to passage corresponding to next equipment under test, next equipment under test is tested, save the stand-by period of restarting test instrumentation, realized quick switching.
Be different from the test of common signal due to the test for high frequency 2.4GHz signal, therefore must design a kind of switch unit that is applicable to radio frequency; Switch unit in the present embodiment as shown in Figure 2, comprise the radio frequency solid relay in the radio frequency transmission field of being exclusively used in that is connected with control unit and the radio frequency solid switch that is connected with radio frequency solid relay and a plurality of equipment under test respectively, such switch unit not only can be applied to radiofrequency signal, and has the good characteristics of shielding.
Because the wireless communication RF signal strength signal intensity is very little, therefore select as follows for the parameter of radio frequency solid switch: operating frequency is 0-18GHz, and insertion loss≤0.2dB, isolation 〉=80dB, switching over time≤15ms, interface are the general anti-level of SMA property male; So not only be suitable for the very little radiofrequency signal of signal strength signal intensity, and its control mode is simple and easy to realize to have simultaneously the low characteristics of cost than the switch of other structures.Wherein, each pin wiring of radio frequency solid switch is as shown in table 1.
Table 1 radio frequency solid switch pin wiring definition
| Pin number | The function definition |
| NO | Often open pin, i.e. acquiescence and the pin of inputting conducting |
| NC | The normal pin that closes, i.e. the pin that acquiescence and input cuts off |
| IN | Input |
| +/- | The switch control end, |
Optionally, if the switching speed of switch unit is had relatively high expectations, and it is lower to control requirement, and switch unit can adopt PIN formula radio-frequency (RF) switch to substitute; Therefore switch unit can be the PIN formula radio-frequency (RF) switch that is connected with control unit and a plurality of equipment under test respectively; PIN formula radio-frequency (RF) switch shows as a variable impedance device in the wireless communication RF signal frequency range, resistance value is added in the direct current at its two ends and controls, and such characteristic makes it control radio-frequency power with less bias current.
Wherein, control unit comprises the single-chip microcomputer that is connected with switch unit; Single-chip microcomputer is connected with as shown in Figure 3 control circuit: the control signal ON/OFF that single-chip microcomputer periodically produces a high-low level is PY4, when this signal is low level, triode V3 cut-off, making triode V2 base stage is high level and then conducting, and its current collection is low level very, relay J 1 closure, make pin 3 and pin 4 conductings, be that 12V is shorted to pin 4, switch to normal pass pin NC thereby control the radio frequency solid switch from often opening pin NO, and then control the strobe state of radio frequency solid switch.When controlling radio frequency solid switch input control voltage; can produce reverse high pulse voltage of moment; this voltage might cause the damage that feeds DC power supply; therefore suppress diode VD13 and VD14 in the indirect transient state of two terminals of control Voltage-output of switch, play the effect that protection feeds DC power supply.When a passage of radio frequency solid switching gate, can be communicated with test instrumentation and this channel attached the first equipment under test, and test; After to be tested completing, by single-chip microcomputer radio frequency solid relay and then the next passage of control radio frequency solid switching gate, can be communicated with test instrumentation and this channel attached the second equipment under test, and test.In this process, saved the stand-by period of restarting test instrumentation in the time of need to testing the second equipment under test in the prior art after testing the first equipment under test, realized quick switching, can complete in order a test that connects to the Devices to test more than two and two, average separate unit can be saved the time of 40S left and right, improves greatly the efficient of production test.
Above execution mode only is used for explanation the utility model; and be not limitation of the utility model; the those of ordinary skill in relevant technologies field; in the situation that do not break away from spirit and scope of the present utility model; can also make a variety of changes and modification, so all technical schemes that are equal to also belong to protection category of the present utility model.
