Specific embodiment
Embodiment electronic test equipment test universal fixture
Present embodiments provide a kind of electronic test equipment test universal fixture, as shown in figure 1, it includes:
Client, the client in the present embodiment adopts computer of the prior art, is equipped with the client and builds
Found the simulation software (the pspice software for example electronic equipment being emulated) of tested electronic equipment phantom, by described
After simulation software sets up the circuit simulation model of tested electronic equipment, this circuit model of simulation run, client obtains emulating quilt
Survey that electronic equipment is normal and fault-signal, and preserve the signal of telecommunication emulation data of each tested pilot.
Server, can obtain the parameter of client and data is analyzed form control signal, described server is adopted
Developed with delphi programming language of the prior art and realize, be stored thereon with analysis and processing program, can obtain to from client
The parameter taking is analyzed processing, and final generation sends out under control parameter, and the server in the present embodiment passes through network connection
Client.
Instrument and equipment, the control for the reception server produces various control parameters, and the parameter providing according to server
Produce various normal or faulty physical signal, and send out.Instrument and equipment in the present embodiment is as shown in figure 1, include conduct
The control unit of control centre, and normal or faulty physical signal for being converted into data signal next for server transmission
Converting unit, wherein control unit adopt the driving based on pxi board for the visual studio developing instrument of the prior art
Program development is realized, and converting unit adopts the signal based on pxi bussing technique of the prior art to produce board；Described control is single
Unit is connected with client by network, and the control signal outfan of control unit connects the signal input part of converting unit, institute
State the normal of converting unit output or faulty physical signal.
Test adapter, the physical signalling for producing instrument and equipment sends follow-up test equipment to, by test
The physical signalling that equipment transmits to instrument and equipment is tested, and finally gives function, the performance of corresponding test equipment, described test
Adapter installs equipment under test instrument connection or test interface additional using universal test panel of the prior art, follow-up test
Equipment is then existing structure in prior art, and the signal input of described test adapter connects instrument by coaxial cable and sets
Standby, the signal output of test adapter is directly connected to test equipment.
The step that the present embodiment is tested to electronic test equipment includes the following steps carrying out successively:
One) staff sets up the circuit simulation model of equipment under test using client, and then simulation run is normal respectively
Or the equipment under test circuit under failure condition, and preserve the signal of telecommunication emulation data of each measured point.
Two) server passes through network from client acquisition signal of telecommunication emulation data, and data is analyzed process, and produces
Various parameters needed for energy controller unit equipment.
Include the following steps carrying out successively in this step again:
1. the emulation data file of server normal or fault-signal after client is loaded into emulation by network, reads
The data of each test point in file, judges the signal type of the data of reading.
The signal type of the data reading wherein in this step includes periodic signal and nonperiodic signal, and periodic signal
Decision process is:
) first data point voltage of record, traversal array is identical with first point until magnitude of voltage, records at first point to the
All data in 2 points of intervals, and with this siding-to-siding block length judge in next interval data whether with data phase in first interval
Same, if error is interior according to this in three numbers, regard as periodic signal；If differed, start continuation time from the second measuring point
Go through searching subsequent point, and repeat said method and judged；If judging in this step that signal is unsatisfactory for the condition of periodic signal,
Not representing measured signal is nonperiodic signal, this is because common periodic signal is square-wave signal believing with sine wave
Number, in order to improve the precision of the present embodiment, first to being whether judgement that square-wave signal is carried out if it is decided that not being in this step
Then need to determine whether sine wave period signal, that is, enter next step.
) experience step) if not judging that signal is periodic signal afterwards, after the emulation of server reading client just
Time and the signal of telecommunication numerical value such as voltage, electric current that in the emulation data file of regular signal or fault-signal, test point is comprised, and
It is saved in array, ergodic data finds maximum and the minima of voltage, calculates the intermediate value of voltage, by cycle criterion
Voltage is less than intermediate value in a upper time point, and future time point then records the time of this point more than intermediate value, after having traveled through array,
Judge that the time difference in each interval predicates periodic signal if less than 10%.
2. processed accordingly according to the signal type reading data, and computing equipment equipment is needed the signal width of generation
Degree and attenuation.
Process for periodic signal in this step is: the frequency of calculating cycle signal, cycle relevant parameter, and according to letter
Number amplitude and instrument and equipment can be generated by signal amplitude limits computing equipment equipment need produce signal amplitude and decay
Amount, and the process for nonperiodic signal is: a computing equipment equipment needs signal amplitude and the attenuation producing；
3. select to need to be handed down to the test point signal of instrument and equipment according to the signal type of data, and by test point signal
It is handed down to instrument and equipment.
Process for periodic signal in this step is: the test point signal intercepting a cycle is handed down to instrument and equipment,
And nonperiodic signal is then needed to issue all data of test point to instrument and equipment.
Three) produce various normal or fault physical signalling by network the reception server after the parameter that instrument and equipment is transmitted
And sent out by test adapter.
Four) after the various normal or physical signalling of fault that test equipment is spread out of by test adapter receiving instrument equipment
This physical signalling is accordingly tested, is finally given the performance of tested electronic equipment.
