Detailed description of the invention
The invention discloses a kind of method and apparatus controlling the operation of tested exemplar, in stable proof box
At a temperature of portion, tested exemplar is tested, improve the normal operational parameters of the tested exemplar that test obtains
Degree of accuracy.
Below the specific embodiment of the invention is described in detail.
Embodiment one
Fig. 1 is a kind of embodiment of the method one schematic flow sheet controlling the operation of tested exemplar of the present invention, described
Method includes:
Step 101: the proof box internal temperature values gathered according to preset sample frequency.
Proof box is provided with temperature sensor, proof box internal temperature values is uploaded in CAN.
Load simulation case (Load Box) gathers the internal temperature of proof box according to preset sample frequency from CAN
Angle value.When implementing, proof box internal temperature values is by RS485 bus transfer to Load Box.
Load Box gathers the preset sample frequency of proof box internal temperature values from CAN can basis
Practical situation is set, and the most specifically limits.Generally, the sampling frequency of Load Box
Rate is very fast, can reflect the true temperature situation in current test case as far as possible.
Step 102: obtaining the first temperature value and the second temperature value, described first temperature value is by currently being gathered
Proof box internal temperature values, described second temperature value is that the last proof box internal temperature values gathered is made
It it is the second temperature value.
Load Box gathers in tryoff from CAN according to default sample frequency sequencing over time
Portion's temperature.The proof box internal temperature values that Load Box is currently gathered from CAN is as the first temperature
Value, described first temperature value reflection current test case internal temperature values.Load Box from CAN in institute
Before stating the first temperature value, the last proof box internal temperature values gathered is as the second temperature value, and described the
The internal temperature of proof box when two temperature value reflection last times gathered proof box internal temperature values.It is to say,
Second temperature value and the first temperature value are gathered from CAN successively by Load Box sequentially in time
Proof box internal temperature values, gathers the second temperature value front, gathers the first temperature value rear.
Step 103: according to described first temperature value, described second temperature value and described preset sample frequency
Calculate Current Temperatures rate of change.
Rate of temperature change f can use formula (1) to calculate, as shown in Figure 2:
Wherein, T1It is the first temperature value, T2Being the second temperature value, v is preset sample frequency.Variations in temperature
Rate f mainly can reflect the current test time dependent situation of case internal temperature.
Step 104: calculate the current temperature difference with the target temperature value preset according to described first temperature value.
The target temperature value preset refers to tested exemplar temperature value when properly functioning, current temperature difference T
Formula (2) can be used to calculate:
ΔT=T1-T0(2)
Wherein, T1It is the first temperature value, reflects current test case internal temperature, T0For target temperature value.
Needing exist for explanation, described default target temperature value is relevant with tested exemplar, can basis
The kind of tested exemplar is specifically arranged.Described default target temperature value can be arranged in proof box,
Default target temperature value is transmitted to Load Box by proof box by CAN；Described default target
Temperature value can also be configured in Load Box as the case may be according to the difference of tested exemplar, this
In do not carry out adding restriction in a day.
Step 105: obtain current test case internal temperature according to described rate of temperature change and the described current temperature difference
State, controls tested exemplar according to described proof box internal temperature state and runs.
Described rate of temperature change can reflect the situation that proof box internal temperature is shaken, and arranges preset temperature and becomes
Rate is interval similar with arranging default target temperature value.Can in proof box kind according to tested exemplar
It is interval that class arranges preset temperature rate of change, then by preset temperature rate of change interval by CAN send to
Load Box；Directly preset temperature rate of change can also be set at Load Box interval.When described temperature becomes
When rate is within preset temperature rate of change interval, (described rate of temperature change becomes less than described preset temperature
The maximum that rate is interval, more than the minima that described preset temperature rate of change is interval), in representing proof box
Portion's rate of temperature change is in allowed limits.
The described current temperature difference can reflect proof box internal temperature and tested exemplar default mesh time properly functioning
Difference between mark temperature, arranges the default temperature difference interval similar with arranging default target temperature value.Permissible
In proof box, the kind according to tested exemplar arranges default temperature difference interval, then is passed through in default temperature difference interval
CAN sends to Load Box；Directly the default temperature difference can also be set at Load Box interval.Work as institute
State the current temperature difference within the default temperature difference interval time (the described current temperature difference is interval less than the described default temperature difference
Maximum, the minima interval more than the described default temperature difference), represent proof box internal temperature values and preset
Target temperature between difference in allowed limits.
As it is shown on figure 3, when described rate of temperature change in preset temperature rate of change interval, and described work as
When the front temperature difference is in default temperature difference interval, current test case internal temperature state is steady statue, controls quilt
Test sample part powers on, and tests tested exemplar.
Now, the shake of proof box internal temperature values is less, and current test case internal temperature values is with pre-
If target temperature value error in allowed limits, represent that now proof box internal temperature state is
Steady statue, meets the condition testing tested exemplar operational factor, and Load Box controls tested exemplar
Power on, test the operational factor of tested exemplar.Load Box is sent to proof box by CAN
Upper electric control signal, proof box powers on to tested exemplar and starts test.
During the operational factor testing tested exemplar, Load Box passes through CAN to test
Case sends simulates the properly functioning required sensor signal of tested exemplar, and monitors the operation of tested exemplar
Operating mode.
As shown in Figure 4, when described rate of temperature change not in preset temperature rate of change interval or described currently
When the temperature difference is not in default temperature difference interval, current test case internal temperature state, for treating steady statue, controls
Tested exemplar powers on, the tested exemplar of delayed test.
When meet described rate of temperature change not in preset temperature rate of change interval and the described current temperature difference not
In in the default temperature difference interval during any one condition, represent that current test case internal temperature state is steady for treating
Determine state.Only meet described rate of temperature change in preset temperature rate of change interval time, the described current temperature difference
Not in default temperature difference interval, represent the shake of now proof box internal temperature values in allowed limits,
But proof box internal temperature values the most not up to tests the condition of the target temperature value preset of tested exemplar；
Only meet the described current temperature difference in the default temperature difference interval time, described rate of temperature change not preset temperature become
In rate interval, represent that now proof box internal temperature values reaches to test the pre-set target temperature of tested exemplar
The condition of value, but now proof box internal temperature shake is relatively big, is not suitable for testing the operation ginseng of tested exemplar
Number.At this time, it may be necessary to after waiting proof box internal temperature value stabilization, more tested exemplar is tested.
As it is shown in figure 5, when described rate of temperature change is not in preset temperature rate of change interval and described
When the current temperature difference is not the most in default temperature difference interval, current test case internal temperature state is adjustment state,
Do not control tested exemplar to power on, do not test detected sample part.
Now, proof box internal temperature values is the most unstable, the most not at the default upper and lower ripple of target temperature value
In dynamic scope, it is impossible to test the operational factor of tested exemplar, need proof box internal temperature values is entered
Test again after Row sum-equal matrix.
As shown in the above, the method have the advantages that:
The proof box internal temperature values gathered according to preset sample frequency；Obtain the first temperature value and the second temperature
Angle value, described first temperature value is the proof box internal temperature values currently gathered, described second temperature value
For the last time gather proof box internal temperature values as the second temperature value；According to described first temperature value,
Described second temperature value and described sample frequency calculate Current Temperatures rate of change；According to described first temperature
Value calculates the current temperature difference with the target temperature value preset；According to described rate of temperature change and the described current temperature difference
Obtain current test case internal temperature state, control tested exemplar according to described proof box internal temperature state
Run, when proof box internal temperature state is steady statue, then controls tested exemplar and power on, test quilt
Test sample part, tests tested exemplar under stable proof box internal temperature state, improves and tests
The degree of accuracy of the normal operational parameters of the tested exemplar arrived, it is to avoid test run is joined by proof box temperature jitter
The impact of number.
Embodiment two
Fig. 6 is that the present invention is a kind of controls embodiment of the method two flow chart that tested exemplar runs, with embodiment
One compares, and when being additionally included in the tested exemplar of test in embodiment two, controls tested exemplar when running into fault
Power-off, described method includes:
Step 601: the proof box internal temperature values gathered according to preset sample frequency.
Step 602: obtain the first temperature value and the second temperature value.
Described first temperature value is the proof box internal temperature values currently gathered, and described second temperature value is
The last proof box internal temperature values gathered is as the second temperature value.
Step 603: according to described first temperature value, described second temperature value and described default sampling frequency
Rate calculates Current Temperatures rate of change.
Step 604: calculate the current temperature difference with the target temperature value preset according to described first temperature value.
Step 605: obtain current test case internal temperature according to described rate of temperature change and the described current temperature difference
State.
Step 606: when described rate of temperature change is in preset temperature rate of change interval, and described current temperature
When difference is in default temperature difference interval, current test case internal temperature state is steady statue, controls detected sample
Part powers on, and tests tested exemplar.
Step 607: when described rate of temperature change is not in preset temperature rate of change interval or the described current temperature difference
Time not in default temperature difference interval, current test case internal temperature state, for treating steady statue, controls tested
Exemplar powers on, the tested exemplar of delayed test.
Step 608: when described rate of temperature change is not in preset temperature rate of change interval, and described currently
When the temperature difference is not the most in default temperature difference interval, current test case internal temperature state is adjustment state, does not controls
Make tested exemplar to power on, do not test detected sample part.
Step 601 is similar with embodiment one to step 608, the description of reference example one, the most no longer
Repeat.
Step 609: when testing tested exemplar, if described first temperature value exceedes presets the highest test temperature
Or less than when presetting minimum test temperature, control tested exemplar power-off, send Fisrt fault letter to proof box
Breath.
Due to the first temperature value reflection current test case internal temperature values, preset if the first temperature value exceedes
Height tests temperature or less than when presetting minimum temperature, represents that current test case internal temperature values has exceeded tested
Exemplar preset the highest test temperature or less than preset minimum temperature, tested exemplar is inside current test case
At a temperature of to will be unable to the operational factor error of properly functioning, measured tested exemplar big.
Now, Load Box sends power down control signal by CAN to proof box, and proof box is to quilt
Test sample part power-off, stops the test to tested exemplar.Meanwhile, Load Box also by CAN to examination
Tryoff sends Fisrt fault information, and notice proof box current test case internal temperature values is beyond can be to quilt
Test sample part carries out the temperature range tested.
Step 610: when testing tested exemplar, if described rate of temperature change is beyond preset temperature rate of change district
Between, control tested exemplar power-off, send the second fault message to proof box.
The jitter conditions of described rate of temperature change reflection proof box internal temperature, if proof box internal temperature is trembled
Dynamic amplitude is excessive, and the most described rate of temperature change then can be interval beyond preset temperature rate of change, now, and test
The shake of case internal temperature can cause the test result error of the operational factor of tested exemplar big.
Now, Load Box sends power down control signal by CAN to proof box, and proof box is to quilt
Test sample part power-off, stops the test to tested exemplar.Meanwhile, Load Box also by CAN to examination
Tryoff sends the second fault message, and notice proof box current test case internal temperature change rate is beyond permissible
The preset temperature rate of change testing tested exemplar is interval.
Step 611: when testing tested exemplar, if receiving the 3rd fault message that proof box sends, control
Make tested exemplar power-off.
When proof box is broken down, it is impossible to tested exemplar proceeds test, then proof box is passed through
CAN sends the 3rd fault message to Load Box, and Load Box passes through CAN to test
Case sends power down control signal, and tested exemplar power-off is given in proof box, stops the test to tested exemplar.
As shown in the above, the present invention also has the advantages that:
During sample is tested by proof box, when proof box internal temperature or proof box
The problems such as fault own cause tested exemplar cannot properly functioning time, Load Box control to tested exemplar
Carry out power-off, stop tested exemplar is tested, after pending fault is got rid of, be further continued for tested exemplar
Test.Which further increases the precision of the operational factor of the tested exemplar recorded, can keep away
Exempt to be caused the operational factor that records not the tested tested exemplar of exemplar test process cannot normally be worked
Accurately.
