The device 01 of measured point is steadily contacted based on detection probe provided in this embodiment, the present embodiment provides a kind of detections
The method that probe stationary contacts measured point, as shown in Fig. 2, this method may include steps of：
Step S11：Obtain current measurement value.
When probe contacts measured point, acquisition module starts to obtain the current measurement value of probe.
Step S12：Calculating difference.
Assuming that the current measurement value of the probe got is B, a upper measured value for probe is A, then, computing module is just
Can by formula Δ=| B-A | the current measurement value of probe and upper one survey is calculated in (taking absolute value to the value of B-A)
The difference DELTA of magnitude.
Step S13：Judge whether difference is less than or equal to preset difference value.
After difference DELTA of the current measurement value that probe is calculated with a upper measured value, judgment module is by Δ and in advance
If difference is compared, judge whether Δ is less than or equal to preset difference value.If Δ be more than preset difference value, return to step S11, if
Δ is less than or equal to preset difference value, thens follow the steps S14 to step S15.
Step S14：Judge whether that continuous n times difference occur and are less than or equal to preset difference value.
Judge that the difference DELTA of the current measurement value and a upper measured value of probe is less than or equal to for the first time in judgment module
After preset difference value, step S11 to step S13 is repeated, until (N is the integer more than 1 to the continuous N of judgment module, is represented advance
The measured value stable degree of setting) it is secondary judge Δ be less than or equal to preset difference value when, it is believed that data stabilization.In the process
In, difference thinks the measured value that current measurement value is stable when being less than or equal to preset difference value, then, which is the equal of
Now think data stabilization after the measured value of continuous N number of stabilization.At this moment, step S15 is executed.If repeating step S11 to step
During rapid S13, if the continuous n of judgment module (n is the integer more than 0, and is less than N) is secondary to judge that Δ is less than or equal in advance
If difference, and judge that Δ is more than preset difference value for (n+1)th time, at this moment can record measured value stable degree again since 0, it will
The Δ judged next time is less than or equal to preset difference value and regards the current measurement value for judging probe for the first time and upper one as
The difference DELTA of measured value is less than or equal to preset difference value, continues to repeat step S11 to the process of step S13, until occurring
The case where continuous n times Δ is less than or equal to preset difference value.
Step S15：Output data stabilization signal.
When continuous n times judge that difference is less than or equal to preset difference value, output module is stablized to user's output data to be believed
Number with prompt user probe measured point has been steadily contacted, data stabilization signal therein can be voice signal, can also be light
The combination of signal or voice signal and optical signal.
The method that measured point is steadily contacted in detection probe provided in this embodiment, due to the current measurement by obtaining probe
Value, the difference based on current measurement value and a upper measured value judge current measurement value and a upper measurement in continuous n times
When the difference of value is less than or equal to preset value, it is believed that at this moment data stabilization can prompt to use to user's output data stabilization signal
Family probe measured point has been steadily contacted so that whether the stabilization of probe no longer by user by observe and measure instrument reading whether
Stablize to judge, to which the subjective factor of people will not be introduced, so that the data measured are more accurate, reliable.
Embodiment two：
The present embodiment provides the device 02 that measured point is steadily contacted in another detection probe, structural schematic diagram such as Fig. 3 institutes
Show, what is different from the first embodiment is that the processor 2 in the present embodiment includes acquisition module 21, computing module 22, judgment module
23, dump block 24 and logging modle 25.
Acquisition module 21 is used to obtain the current measurement value of probe 1；Computing module 22 is used to calculate the current measurement of probe 1
The difference of value and a upper measured value for probe 1；Judgment module 23 is for judging whether 22 calculated difference of computing module is small
In or be equal to preset difference value, judge difference less than or equal to preset difference value when, measured value stable degree is first added 1, then judge
Whether measured value stable degree is greater than or equal to pre-set measured value stable degree N；Output module 3 is used in judgment module
23 judge measured value stable degree be greater than or equal to N when, to user's output data stabilization signal with prompt user probe it is steady
Surely measured point is contacted, data stabilization signal therein can be voice signal, can also be optical signal, can also be voice signal
And the combination of optical signal；Dump block 24 is used for when judgment module 23 judges that difference is more than preset difference value, and measured value is steady
Determine number and is set to 0；Logging modle 25 is used in output module 3 to user's output data stabilization signal to prompt user's probe steady
When contacting measured point surely, while this measurement data is recorded, can using pop one's head in 1 current measurement value as this measurement
Data are recorded, can also be using the average value of N number of measured value when continuously N number of difference is less than or equal to preset difference value as this
Secondary measurement data is recorded.
The device 02 of measured point is steadily contacted based on detection probe provided in this embodiment, the present embodiment provides another kinds to examine
The method that measured point is steadily contacted in probing head, as shown in figure 4, this method may include steps of：
Step S21：Obtain current measurement value.
When using measuring instrument to be measured measure, when probe contacts measured point, acquisition module starts to obtain
The current measurement value of probe, for example, the current measurement value once popped one's head in can be obtained every t seconds time.
Step S22：Calculating difference.
Assuming that the current measurement value for the probe that acquisition module is got is B, a upper measured value for probe is A, calculates mould
The current measurement value B of probe can be compared by block with a upper measured value A for probe, can by formula Δ=| B-A | (i.e.
Take absolute value to the value of B-A) be calculated current measurement value and probe a upper measured value difference DELTA.
Step S23：Judge whether difference is less than or equal to preset difference value.
After the difference DELTA of the current measurement value popped one's head in a upper measured value, judgment module by Δ with it is default poor
Value is compared, and judges whether Δ is less than or equal to preset difference value.If Δ is more than preset difference value, S24 is thened follow the steps；If Δ is small
In or equal to preset difference value, S25 is thened follow the steps to step S27.In this process, think when Δ is less than or equal to preset difference value
Current measurement value is stable measured value, can record time that current measurement value is stable measured value with measured value stable degree
Number.
Step S24：Measured value stable degree is set to 0.
When judging that the difference DELTA between the current measurement value and a upper measured value of probe is more than preset difference value, carry out
Measured value stable degree can be set to 0, then be executed since step S21 again by clear operation, dump block.
Step S25：Measured value stable degree adds 1.
Difference DELTA of the judgment module between the current measurement value and a upper measured value for judging to pop one's head in is less than or equal to
When preset difference value, measure value stabilization number adds 1 operation certainly, and the value of measured value stable degree is added 1.
Step S26：Judge whether measured value stable degree is greater than or equal to N.
Measured value stable degree is compared by judgment module with N, judges whether the measured value stable degree is more than or waits
In N, N therein is the integer more than 1, represents pre-set measured value stable degree, for example the value of N can take 5.If the survey
Magnitude stable degree is less than N, then is executed since step S21 again；If the measured value stable degree is greater than or equal to N, recognize
It is stable for data, step S27 is executed at this time.
Step S27：Output data stabilization signal simultaneously records measurement data.
When judging that measured value stable degree is greater than or equal to N, output module to user's output data stabilization signal,
In data stabilization signal can be voice signal, for example send out the sound of " ticking ", data stabilization signal can also be optical signal,
For example indicator light is bright, alternatively, data stabilization signal can also be the combination of voice signal and optical signal, for example is sending out " ticking "
Indicator light is also bright when sound, and measured point has been steadily contacted to prompt user to pop one's head in this, meanwhile, logging modle can working as probe
Preceding measured value is recorded as effective measurement data, alternatively, in order to keep the measurement data of record more accurate, logging modle
The average value that the measured value of this N number of stabilization can first be calculated, then remembers the average value as effective measurement data
Record.
In order to clearly embody the purpose of the present invention, make further to illustrate based on the above method
It is bright.
Assuming that preset difference value is Const_delt, measured value stable degree is indicated with count, and the initial value of count is 0,
Pre-set measured value stable degree N is 5 times.Behind probe contacts measured point, the current measurement value for getting probe is a1, and
A upper measured value for probe is a0, can calculate difference DELTA 1=| a1-a0 |, value is less than Const_delt, then count=0
+ 1=1, count are less than 5, continue the current measurement value for obtaining probe；The current measurement value got at this time is a2, can be calculated
Difference DELTA 2=| a2-a1 |, value is more than Const_delt, then count is set to 0, i.e., count=0 at this time, continues to obtain and visit
The current measurement value of head；The current measurement value got at this time is a3, can calculate difference DELTA 3=| a3-a2 |, value is less than
Const_delt, then count=0+1=1, count continue the current measurement value for obtaining probe less than 5；Follow-up same side
The calculated difference DELTA 4 of method, Δ 5 ... Δ 7 are respectively less than Const_delt, at this moment count=1+1+1+1+1=5, i.e. count's
Value is equal to N, it is believed that current measurement value is stable, that is, popping one's head in steadily contacts measured point, that is to say, that when continuous 5
Data stabilization when difference is respectively less than Const_delt, the data at this moment measured will be it is effective, can use voice signal or
The combination of person's optical signal or voice signal and optical signal steadily contacts measured point to prompt user to pop one's head in, and will be current
Measured value records one-shot measurement data as virtual value, or using the average value of the data of this 5 times measurements as virtual value.It
Afterwards, if occurring the case where difference is more than Const_delt again, for example there is probe and have the case where shaking, or probe
Being accessed another measured point situation again, then the original state that can be again 0 from count re-executes this process, otherwise,
Current data stabilization state is kept to be measured until terminating.The process does not need engineer by observing and measuring the reading of instrument
No stabilization come judge probe whether measured point has been steadily contacted, because without introducing people subjective factor so that measurement data
It is relatively reliable；Meanwhile the record of measurement data can be automatically recorded by measuring instrument, gone without engineer it is manually recorded,
To reduce the measurement workload of engineer.
The method that measured point is steadily contacted in detection probe provided in this embodiment, by obtaining the current measurement value of probe,
The difference for calculating a upper measured value for current measurement value and probe, judges whether the difference is less than or equal to preset difference value,
Measured value stable degree is first added 1 by the difference when being less than or equal to preset difference value, then judges whether measured value stable degree is more than
Or it is equal to pre-set measured value stable degree N, it is steady to user's output data when measured value stable degree is greater than or equal to N
Signal is determined to prompt user's probe that measured point has been steadily contacted, and records one-shot measurement data.In this way, can automatic decision number
Whether according to stablizing, being equivalent to can pop one's head in whether measured point is steadily contacted with automatic decision, pass through observed reading without user
Whether stablize to judge whether probe has been steadily contacted measured point, therefore just will not also introduce the subjective factor of people, this makes
The data of measurement are more accurate, reliable.Meanwhile it being steadily contacted to user's output data stabilization signal with prompting user to pop one's head in
It when measured point, is recorded current measurement value as measurement data, obtains effective measurement data, can realized steady to data
Automatically recording for measurement data after fixed, makes the record of measurement data automate.Especially need measure multi-group data when
It waits, it is no longer necessary to which engineer puts down to be picked up probe after the manually recorded one group of measurement data of probe and repeat a measurement again
Action, so as to effectively reduce the measurement workload of engineer.
