In addition, the present invention relates to have the testing fixture (intelligent inspection unit) and the control device (FA equipment such as sequence controller, motion controller, numerical control device and robot) of aforesaid data recording equipment.
Background technology
The signal that well-known handlebar becomes the check measurement object is as measurement data and by the data recording equipment of time sequential recording.
In this existing apparatus, be taken into analog electrical signal as the check measurement object by data bus, and utilize data input unit to carry out the AD conversion, making becomes numerical data, be transferred to data recording portion from data input unit then, be lastly recorded in data recording portion.
As the 1st existing apparatus is to constitute like this, the data recording equipment of intelligence inspection unit comprises AD converter, cPCI bus (compact PCI bus, the mini PCI bus) and storer, obtain the AD data by the cPCI bus from AD converter, be stored in storer (for example with reference to non-patent literature 1) then.
Above-mentioned non-patent literature 1 described the 1st existing apparatus is to constitute like this, it is under the control of program, obtain the current data that AD converter is preserved by the cPCI bus, and be stored in storer, for example, with Get NewData[V] FB obtains data from AD converter, and is stored in the D device with floating type.
Therefore, can obtain the data number in the storer allowed band, but the sampling period (measuring period) depend on program speed, if data channel (CH) number increases, then the sampling period is elongated.
In addition, proposed such scheme as above-mentioned non-patent literature 1 described the 2nd existing apparatus, it utilizes the high-performance AD converter, and in the data that AD converter is only preserved the regulation number of samples, the intact back of summary record is stored in storer by the cPCI bus.

Embodiment
Form of implementation 1.
The block scheme of Fig. 1 data recording equipment that to be expression relevant with form of implementation of the present invention 1.
Among Fig. 1, data recording equipment comprises data input device 1, data bus means 2, passes through data control unit 3, the data record unit 4 that is connected with data control unit 3 and data buffering memory storage 5 that data bus means 2 is connected with data input device 1.
Data bus means 2 is transferred to data control unit 3 to the measurement data that is taken into by data input device 1.Specifically, the cPCI bus that data bus means is passed through by numerical data etc. constitutes, and plays a role during swap data between data input device 1 (for example A/D converter) and data control unit 3.
Data buffering memory storage 5 comprises the buffer area 6 that interim storage of measurement data is used.Specifically, the buffer areas 6 in the data buffering memory storage 5 are made of the storage area (RAM) that data control unit 3 (CPU) uses, and when the program of CPU is carried out, use under the situation when keeping data etc.
Fig. 2 is the block scheme of the action of expression data recording equipment shown in Figure 1, and dotted arrow is represented data stream.
Among Fig. 2, data control unit 3 can be divided into data and obtain two holding functions such as control device 31 and controller for recording data 32.
Data obtain control device 31 and obtain data by data bus means 2 from data input device 1, and are stored in the buffer area 6 of data buffering memory storage 5 temporarily.
Controller for recording data 32 is read the data in the buffer area 6 that temporarily is stored in data buffering memory storage 5, and is recorded on the data record unit 4, removes the data in the buffer area 6 that temporarily is stored in data buffering memory storage 5 simultaneously.
Fig. 3 is the process flow diagram of sampling action of the measurement data of expression form of implementation 1 of the present invention, and Fig. 4 is the key diagram that utilizes the motion flow of slip chart diagrammatic sketch 3.
Below, on one side with reference to figure 2～Fig. 4, the action of the data control unit 3 of form of implementation of the present invention 1 shown in Figure 1 is described on one side.
Among Fig. 3, at first specify sampling condition, then according to sampling condition, the deal with data of setting is each time counted N (step S1).
Same as described above, the time t (N) that needs that each time N data is write data record unit 4 (for example HDD) can represent with following formula (1).
t(N)＝δ×N+κ …(1)
In the formula (1), δ needs the time to what data write data record unit 4 (for example HDD), κ be (irrelevant) with the data number write data recording equipment 4 (for example HDD) each time need the time (expense).
Here, if the sampling period is made as τ, need interim stores processor (step S4 described later) time to be made as ε, then deal with data is each time counted N as long as the formula (3) below satisfying decides.
τ-ε>δ×N+κ …(3)
Yet, needing to consider the limit of sampling period τ, is not to obtain deal with data to count N under whole situations, says, under the situation of the formula (4) below sampling period τ satisfies or any one condition of formula (5), just the deal with data that can not set is each time counted N.
τ<δ …(4)
τ<κ …(5)
In addition, if count N no matter have what kind of deal with data, under the situation of the sampling period τ that can not satisfy above-mentioned formula (3), then can not sample, so the such sampling period τ that exists the deal with data that satisfies formula (3) to count N also is the ultimate value that can sample.
Get back to Fig. 3, data control unit 3 is then specified sampling condition and is set deal with data and count N (step S1), begins sampling (step S2), and whether the number of judging measurement data reaches final summary record count (step S3).
Among the step S3, do not reach summary record and count (promptly if be judged to be, NO), then the data in the data control unit 3 obtain control device 31 at each sampling period τ, obtain measurement data by data bus means 2 from data input device 1, and the measurement data that obtains is stored in the buffer area 6 of data buffering memory storage 5 (step S4) temporarily.
Then, be cleared during with reference to initial setting and will adding 1 counter (not shown) before the execution in step S4, judge whether to have carried out processing (Counter Value=N) (the step S5) of N step 4, do not carry out N time (promptly if be judged to be, NO), then counter is added 1, the while is execution in step S4 once more.
On the other hand, among the step S5, carried out N step S4 (promptly if be judged as, YES), then the controller for recording data 32 in the data control unit 3 is read N measurement data of the buffer area 6 that temporarily is stored in data buffering memory storage 5, and be recorded in data record unit 4, and remove N the measurement data (step S6) in the buffer area 6 that temporarily is stored in data buffering memory storage 5 then, get back to step S3 then.
At this moment, as shown in Figure 4, finish after the interim stores processor (step S4) of buffer area 6 at every turn, in sampling period τ, carry out other processing.
Equally, finish, in sampling period τ, carry out other processing to the interim stores processor (step S4) of buffer area 6 or after the N of data record unit 4 data recording and processing (step S6).
By repeated execution of steps S4～S6, among the step S3, if being judged as the measurement data number reaches final summary record and counts (promptly, YES), then the controller for recording data 32 in the data control unit 3 is read the whole measurement data in the buffer area 6 that temporarily is stored in data buffering memory storage 5, and be recorded in data record unit 4, remove the whole measurement data (step S7) in the buffer area 6 that temporarily is stored in data buffering memory storage 5 then, finish the sampling processing routine (step S8) of Fig. 3 then.
By above-mentioned processing, can reduce the number of processes that writes, and increase each time to the data volume that writes of data record unit 4 to data record unit 4 (HDD), make the expense that writes that can relatively reduce to data record unit 4.
Its result, as data record unit 4, even under the situation of the medium (HDD) that the utilization data write time each time is long, also can realize that (that is, long-time) sampled data that large-scale summary record is counted is sampled, also assurance can not be lost and be connected continuously with the high-speed sampling cycle.
In addition, even carrying out above-mentioned data sink summary journal, also can be suppressed to Min. to the influence of processing to other.
In addition, because the specialized equipment of high price that especially need not be relevant with above-mentioned processing, so can realize data recording equipment cheaply.
In addition, among Fig. 2, be the function setting of controller for recording data 32 in data control unit 3, but also for example Fig. 5 is such, controller for recording data 32 is arranged in the data record unit 4, in this case, also can obtains action effect same as described above.
Form of implementation 2.
In addition, in above-mentioned form of implementation 1 (with reference to figure 1 and Fig. 2), in data buffering memory storage 5, be provided with a buffer area 6, but also a plurality of buffer areas can be set.
For example, in above-mentioned form of implementation 1, be that the tentation data recording processing is than the quickish situation of sampling processing, therefore need not buffer area 6 is constituted double buffer, but under the situation of sampling processing than above-mentioned more high speed, because the data recording time can't be caught up with sampling interval, so can not realize with the structure of above-mentioned (Fig. 1, Fig. 2).
Therefore, be preferably under the situation of high-speed sampling, for example adopt the double buffer mode, during buffering in a buffer area (interim storage) data, measurement data in another the buffer area is carried out recording processing, by like this, can reliable recording high-speed sampling data.
In addition, double buffer has various uses, generally in record, adopts gathering the mode that writes data record unit after the uniform data storage.
Fig. 6 is the block scheme of the expression data recording equipment relevant with form of implementation of the present invention 2 that be provided with a plurality of buffer area 6a, 6b.
In addition, Fig. 7 is the block scheme of the action of expression data recording equipment shown in Figure 6, and dotted arrow is represented the data stream of initial setting.The data stream of (setting when using buffer zone conversely) when in addition, the dash-dot arrows in Fig. 7 is represented to handle next time.
In Fig. 6 and Fig. 7, give label same as described above for the part identical with above-mentioned (with reference to figure 1 and Fig. 2), perhaps additional " A " and omission are described in detail behind label.
As shown in Figure 6 and Figure 7, data buffering memory storage 5A has a plurality of buffer area 6a and 6b.
In addition, a plurality of buffer area 6a and 6b can realize by the double buffer (seeing it is single buffer area from the outside) of the dual structure of the data area of buffer area 6, also can be by being that realize a plurality of buffer areas in appearance.
In addition, data control unit 3 is performed such data recording control, described data control unit 3 the measurement data this time that obtain from data input device 1 by data bus means 2 be stored in temporarily a plurality of buffer area 6a and the 6b a buffer area (for example, shown in dotted arrow, buffer area 6a), simultaneously be stored among a plurality of buffer area 6a and the 6b another buffer area (for example, shown in dotted arrow, buffer area 6b) last time measurement data record at data record unit 4.
Fig. 8 is the process flow diagram of sampling action of the measurement data of expression form of implementation 2 of the present invention, and Fig. 9 is the key diagram that utilizes the motion flow of slip chart diagrammatic sketch 8.
Among Fig. 8 and Fig. 9, give label same as described above for the processing identical with above-mentioned (with reference to figure 3 and Fig. 4), perhaps additional " A " and omission are described in detail behind label.
Below, on one side with reference to figure 7～Fig. 9, the action of the data control unit 3 of form of implementation of the present invention 2 shown in Figure 8 is described on one side.
Among Fig. 8, at first specify sampling condition, and the deal with data of setting is each time counted N (step S1).
Here, same as described above, can need time t (N) (processing time of step S6A described later) to what N data write data record unit 4 each time with following formula (1) expression.
t(N)＝δ×N+κ …(1)
In addition, if the sampling period is made as τ, need interim stores processor (step S4A) time to be made as ε, then deal with data is each time counted N as long as the formula (6) below satisfying decides.
(τ-ε)×N>δ×N+κ …(6)
Yet, as mentioned above,, can not set deal with data and count N if sampling period τ satisfies any one condition in formula (4) or the formula (5).
In this case, compare with aforementioned form of implementation 1, though surplus is arranged on condition, but it is same as described above, to not satisfying the sampling period τ of above-mentioned formula (6), can not sample, so the such sampling period τ that exists the deal with data that satisfies formula (6) to count N also is the ultimate value that can sample.
Get back to Fig. 8, then step S1 begins sampling (step S2A).
At this moment, the data in the data control unit 3 obtain control device 31 and are initially set " using buffer area 6a ".
Judge whether to reach summary record count (step S3) then, among the step S3, if not reaching summary record counts, then data obtain control device 31 each sampling period τ are obtained measurement data by data bus means 2 from data input device 1, and are stored in a side (being buffer area 6a during initial setting) (step S4A) who is set among buffer area 6a and the 6b temporarily.
Then, judge whether to have carried out N step S4AS and handle (step S5), if do not carry out N time, execution in step S4A once more then.
On the other hand, if having carried out N step S4A handles, then conversely (for example the buffer area of data acquisition control device 31 uses, after 6a → 6b) set, processing (for example, 6b) was read in 32 pairs of buffer areas of using last time of controller for recording data, read N measurement data of interim storage and be recorded on the data record unit 4, (for example, 6b) N in a measurement data (step S6A) is got back to step S3 to remove the buffer area that temporarily is stored in use last time then.
At this moment, as shown in Figure 9, finish after the interim stores processor (step S4A) of buffer area 6a or 6b at every turn, in sampling period τ, carry out other processing.
In addition, the execution object of setting interim stores processor conversely (for example, behind the 6a → 6b), carries out the next one of step S6A and handles, behind the end step S6A, carry out other processing in sampling period τ.
Then, in step S3, reach summary record and count (promptly if be judged as, YES), then conversely (for example the buffer area of data acquisition control device 31 uses, after 6a → 6b) sets, to the buffer area of using last time (for example, 6b) read processing, read whole measurement data of interim storage and be recorded on the data record unit 4, remove then and be stored in buffer area (for example, 6b) the whole measurement data of using last time (step S7A) in, and end sampling (step S8) temporarily.
In above-mentioned form of implementation 1 (with reference to figure 3), in order to guarantee that sampled data is not lost and to connect continuously, in the interim next time stores processor (step S4) of beginning before, must necessarily finish the determination processing of carrying out for N time (step S5), and step S5 need count N according to the deal with data that the sampling period τ that sets strictly adjusts each time.
Yet, according to form of implementation 2 of the present invention (with reference to figure 8), even the N data recording and processing (step S6A) after carrying out carry out judging for N time is carried out by interim stores processor (step S4A) repeatedly, can guarantee that also sampled data is not lost and connection continuously.
Therefore, step S6A need not to adjust scrupulously according to the sampling period τ that sets the data number N of single treatment, can sample reliably.
Specifically, in the above-mentioned form of implementation 1, if sampling period τ shortens and improves under the situation of sample rate, no matter how adjust N, the situation that meeting generation step S6A does not finish before this step S4A and step S4A next time, but in the form of implementation of the present invention 2, carry out because step S6A also can cross over a plurality of step S4A, even, also can adapt so sampling period τ shortens (raising sample rate).
In addition, in the form of implementation 2 of the present invention,, also need to adjust data number N,, make during step S4A carries out N time and can get final product by completing steps S6A as long as adjust data number N in order to guarantee that sampled data is not lost and to connect continuously.
Same as described above in addition, because the specialized equipment of high price that especially need not be relevant with above-mentioned processing, so can realize data recording equipment cheaply.
Form of implementation 3.
Do not mention the distribution (guaranteeing) of buffer area in the above-mentioned form of implementation 1 and 2, but data control unit 3 also can dynamic assignment buffer area 6 (6a and 6b).
Figure 10 is a process flow diagram of partly representing the action of the data recording equipment relevant with form of implementation of the present invention 3, the situation of expression dynamic assignment buffer area.
Among Figure 10, give label same as described above, perhaps omit diagram and omit detailed description for the processing identical with above-mentioned (with reference to figure 3 and Fig. 8).
In addition, as the structure of the data recording equipment of form of implementation 3 of the present invention, the data recording equipment shown in any one in can application drawing 1 Fig. 2 Fig. 5～Fig. 7.
At first, data control unit 3 is specified sampling condition, and according to behind the sampling condition setting N (step S1), comes dynamic assignment buffer area (step S10) according to N.
Below, same as described above, begin sampling (step S2 and S2A).
For example, in the above-mentioned form of implementation 1 and 2,, need to adjust data number N in order to guarantee that sampled data is not lost and to connect continuously, make during carrying out N interim stores processor (step S4 and S4A), can finish the N data recording and processing of carrying out after judging for N time (step S6A).
At this moment, because as influence the key element of the adjustment of data number N, sampling period, sampling CH number are arranged, to the expense of time of access process each time of data record unit 4 etc., so need to set the data number N that attach these key elements.
That is, though adjust data number N according to sampling condition, buffer area 6 (6a and 6b) need guarantee to store N the size that measurement data is such.
Therefore, in the above-mentioned form of implementation 1 and 2, in order to guarantee that sampled data is not lost and to connect continuously, the setting of any sampling condition is needed all to guarantee that N data can deposit such size (data of the maximum number N that can produce can deposit such size in) in.
The problem that this situation exists is, efficient low (waste), and system need adorn bigger storer sometimes.
With above-mentioned different be, form of implementation 3 of the present invention is counted N according to the deal with data of setting based on sampling condition each time, dynamically guarantees (distribution) impact damper, by the above-mentioned waste of such elimination, its result, entire system can be used limited storer effectively.
Promptly, data control unit 3 is according to the size based on sampling period of measurement data, perhaps based on the size of the port number of measurement data, perhaps based on the size to access process time of data record unit 4, dynamic assignment buffer area 6 (6a and 6b) is by can effectively using storer like this.
In addition, owing to do not need the specialized equipment of the high price relevant with above-mentioned processing, so can realize data recording equipment cheaply.
Form of implementation 4.
In the above-mentioned form of implementation 3, be to suppose HDD write time δ or the overhead time κ that uses when utilizing preassigned fixed value to count N as the decision deal with data, and be illustrated, but data control unit 3 also can measured data record cell 4 carries out data recording to move the needed access process time, and according to the big or small dynamic assignment buffer area 6 (6a and 6b) of elapsed time.
For example, under the situation of utilizing fixed value δ and κ, might be a good distance away with the value of real system, so can't determine more accurate deal with data to count N, in the data recording and processing abnormal action can take place.Therefore, preferably utilize dynamic assignment to avoid abnormal action of data recording and processing.
The process flow diagram of the action of Figure 11 data recording equipment that to be expression relevant with form of implementation of the present invention 4 is represented the situation of coming dynamic assignment buffer area 6 (6a and 6b) according to the size of elapsed time.
Among Figure 11, give label same as described above, perhaps omit diagram and omit detailed description for the processing identical with above-mentioned (with reference to figure 3, Fig. 8 and Figure 10).
In addition, as the structure of the data recording equipment of form of implementation 4 of the present invention, can use the data recording equipment shown in any one among Fig. 1 Fig. 2 Fig. 5～Fig. 7.
In this case, data control unit 3 carries out data recording according to data record unit 4 and moves the size of needed time, dynamic assignment buffer area 6 (6a and 6b).
At first, data control unit 3 is specified sampling conditions (step S1A), and the data record unit of setting 4 is carried out sky writes, and measures the processing time, by the expense (step S1B) of such actual measurement access process time each time.
Then, according to the elapsed time setting data number N (step S1C) of the expense of sampling condition of setting and actual measurement, and according to data number N dynamic assignment buffer area 6 (6a and 6b) (step S10).
Below, same as described above, begin sampling (step S2 and S2A).
Specifically, carry out the expense actual measurement of access process time each time by following step S11～S13 and handle (step S1B).
At first, what actual measurement write fewer data volume needs time T 1 (step S11), and what then actual measurement write many data volumes needs time T 2 (step S12).
At last, utilize the mistiming (T2-T1) of elapsed time T2 and T1, calculate the elapsed time (step S13) of expense.
Specifically, by separating based on the following simultaneous equations (1a) of above-mentioned formula (1) and (1b), can be in the hope of suc as formula (7) and such write time δ and the overhead time κ of formula (8).
T1＝t(N1)＝δ×N1+κ?…(1a)
T2＝t(N2)＝δ×N2+κ?…(1b)
δ＝(T1-T2)/(N1-N2)?…(7)
κ＝T1-N1(T1-T2)/(N1-N2)…(8)
For example, in the above-mentioned form of implementation 3, be the data number N that sets according to based on sampling condition, dynamically guaranteed (distribution) impact damper (step S10), at this moment, key element as according to sampling condition setting data number N time the and subsidiary " to the expense of access time each time of data record unit 4 " is different according to the kind of record cell 4 with factor.
Therefore, in fact, need come setting data number N according to the expense of the maximum that it is contemplated that as data record unit 4.That is, the problem of existence is, because the size of the buffer area 6 (6a and 6b) of dynamically guaranteeing is also distributed greatlyyer according to the expense of maximum, so efficient low (waste).
With above-mentioned different be, because the data record unit 4 that 4 pairs of forms of implementation of the present invention utilize sampling condition to set is surveyed the expense of access process times each time, the deal with data of utilizing the elapsed time to set is each time again counted N, set the size of the buffer area of distributing 6 (6a and 6b) then according to the data number N that sets, so can eliminate aforesaid waste, entire system can effectively be used limited storer as a result.
In addition, owing to do not need the specialized equipment of the high price relevant with above-mentioned processing, so can realize data recording equipment cheaply.

In addition, owing to do not need the specialized equipment of the high price relevant with above-mentioned processing, so can realize data recording equipment cheaply.
In addition, in this case, also according to based on the size to access process time of data record cell 4a and 4b, dynamic assignment buffer area 6 is so can effectively use storer.
Form of implementation 6.
In the above-mentioned form of implementation 1～5, be to be provided with a data control device 3, but also a plurality of data control units can be set.
Figure 14 is the block scheme of the expression data recording equipment relevant with the form of implementation of the present invention 6 that is provided with a plurality of data control unit 3a and 3b.
Among Figure 14, data control unit 3a that is set up in parallel and 3b possess data buffering memory storage 5a and 5b separately, and each data buffering memory storage 5a and 5b have independent buffer area 6a and 6b.That is, in this case, also can comprise a plurality of buffer area 6a and 6b in appearance.
In addition, data record unit 4E comprises respectively and each data control unit 3a and corresponding data recording area 7a and the 7b of 3b.Specifically, data recording area 7a and 7b are made of document data record.
In this case, the species number of the data recording and processing of data recording area 7a in data control unit 3a and 3b and the data record unit 4E and 7b is corresponding.
That is, data control unit 3a and 3b carry out the control of the data recording of data record cell 4E, make corresponding with the species number of the interior data recording and processing of data record unit 4E.
Figure 15 utilizes the part sequential chart to represent the key diagram of the action of device shown in Figure 14.
Among Figure 15, the below express time stream (sequential chart) of dotted line, data stream is represented in the top of dotted line, frame of broken lines is represented the data recording control and treatment.
In addition, step S4a with S4b is and the identical processing of above-mentioned step S4 (S4A), and is corresponding with data control unit 3a and the action of 3b in Figure 14 respectively.
Equally, step S6a with S6b is and the identical processing of above-mentioned step S6 (S6A and S6D), and is corresponding with data control unit 3a and the action of 3b in Figure 14 respectively.
In addition, as the sampling condition of each data control unit 3a and 3b, the frequency f 1 of establishing sampling a (CH1) is 1kHz, and the frequency f 2 of establishing sampling b (CH2) is 2kHz.
In this case, at first in step S4b, " value 1 " of the following CH2 of condition at sampling b (2kHz) is stored among the 6b of buffer area temporarily, after then other are handled, in next procedure S4b, be stored among the 6b of buffer area in " value 2 " of the following CH2 of condition of sampling b (2kHz) temporarily.
Secondly, among the step S4a after then other are handled, " value 3 " of the following CH1 of condition at sampling a (1kHz) is stored among the 6a of buffer area temporarily, among the step S4b after then other are handled, be stored among the 6b of buffer area in " value 4 " of the following CH2 of condition of the b (2kHz) that samples temporarily.
Then, among the step S6b after the interim stores processor (step S4b) of " value 4 " of just finishing CH2, the measurement data " value 1, value 2, value 4 " in the 6b of buffer area is transferred to the data recording area 7b in the data recording equipment 7E.
Then to the data transmission and processing (step S6b) of data recording area 7b afterwards, among the step S4b after the processing that executes other, as required the data value of CH2 is stored among the 6b of buffer area temporarily.
Secondly, among the step S4a after then other are handled, be stored among the 6a of buffer area in " value 6 " of the following CH1 of condition of a (1kHz) that samples temporarily.
Then, among the step S6a after the interim stores processor (step S4a) of " value 6 " of just finishing CH1, the measurement data in the 6a of buffer area " value 3 and value 6 " is transferred among the data recording area 7a in the data recording equipment 7E.
Below, data control unit 3a and 3b repeat above-mentioned processing, till reaching final entry and counting.
According to form of implementation 6 of the present invention, even there is the sampling of a plurality of different conditions since can according to separately independently task (processings) carry out sampling processing, so can carry out the sampling of different condition simultaneously, can carry out different a plurality of records of sampling simultaneously.
In addition, under the situation of form of implementation 6 of the present invention, because the step S4a in the above-mentioned processing compares with above-mentioned form of implementation 5 with the contents processing that S4b and step S6a and S6b need and wants simple, so can alleviate the burden of entire process, total system can be carried out processing at a high speed as a result.
In addition, owing to do not need the specialized equipment of the high price relevant with above-mentioned processing, so can realize data recording equipment cheaply.
Yet, can find out significantly from Figure 15, because sampling a and b move independently of each other, time shaft between data recording area 7a and the data recording area 7b inconsistent (not at identical time shaft executive logging) is so even represent data recording area 7a also nonsensical in identical figure with 7B.That is, because sampling a is to carry out record with different sample frequency f1 and f2 with b, so even execution obtains the processing such as difference of each measurement data of sampling a and b also without any meaning.
Form of implementation 7.
In above-mentioned form of implementation 6 (with reference to Figure 14), be utilize two data control device 3a and 3b (two tasks) to carry out independently to separately buffer area 6a and 6b CH handles, handle but also can utilize a data control device 3 (task) that a plurality of CH are carried out in a buffer area 6 of double buffer structure.
The block scheme of Figure 16 data recording equipment that to be expression relevant with form of implementation of the present invention 7 represents to utilize a data control device 3 to control situation to the data recording of data recording area 7a and 7b.
Among Figure 16, can be made as the double buffer structure to the buffer area 6 of data buffering memory storage 5, also can as above-mentioned (with reference to figure 6), be set at buffer area 6 a plurality of.
In addition, also can be with combinations thereof, buffer area 6 is set at a plurality of, simultaneously each buffer area 6 is set at the double buffer structure.
Figure 17 is the process flow diagram of the action of expression device shown in Figure 16, gives identical label for the processing identical with above-mentioned (with reference to figure 3), and omits and describe in detail.
Figure 18 is the key diagram that utilizes the stream of action of part slip chart diagrammatic sketch 16, and is identical with above-mentioned (with reference to Figure 15), and as sampling condition, the frequency f 1 of establishing sampling a (CH1) is 1kHz, and the frequency f 2 of establishing sampling b (CH2) is 2kHz.
In addition, Figure 18 represents sample a and b both sides are recorded in the situation of public buffer area 6.
In this case, the corresponding sampling period of lowest common multiple of utilization and each sampling period f1 and the f2 of CH1 and CH2, the processing of execution in step S4E.
That is, in this case, as a result the sampling period be with the sample frequency f1 of CH1 (the sample frequency f2 of the CH2 of=1kHz) twice (=2kHz) corresponding τ 2 (=1/f2).
That is, among Figure 18, utilize the measurement data of the CH that 2 acquisitions of sampling period τ of CH2 should obtain.
If there is no under the data conditions of the CH that should obtain, in step S4E, do not carry out any processing.
Then, on one side with reference to Figure 17 and Figure 18, the action of form of implementation of the present invention 7 shown in Figure 16 is described on one side.
Among Figure 17, at first specify a plurality of sampling conditions (step S1E), begin sampling (step S2) then.
Then, do not count if reach summary record, then data obtain control device 31 to each sampling period τ (=τ 2), obtain measurement data by data bus means 2 from data input device 1, and are stored in (step S4E) in the buffer area 6 temporarily.
Repeating step S4E, in the moment that executes N step S4E, controller for recording data 32 is read the measurement data that temporarily is stored in the buffer area 6, and according to sampling condition, be recorded on the data recording area 7a or 7b of data record unit 4E, and remove the measurement data (step S6E) that temporarily is stored in the buffer area 6.
Below, reaching the moment that final summary record is counted, execution in step S7 and S8 finish the sampling processing routine of Figure 17 then.
Specifically, for example shown in Figure 180, at first, in step S4E, CH2 " value 1 " is temporarily stored in the buffer area 6, and in following step S4E, " value 2 " of CH2 and " value 3 " of CH1 are temporarily stored in the buffer area 6.
In addition, in next procedure S4E, CH2 " value 4 " is temporarily stored in the buffer area 6, and in following step S4E, " value 5 " of CH2 and " value 6 " of CH1 are temporarily stored in the buffer area 6.
Then, among the step S6E, CH2 in the buffer area 6 " value 1, value 2, value 4, value 5 " is transferred among the data recording area 7b of data record unit 4E, and the CH1 that buffer area 6 is interior " value 3, value 6 " is transferred among the data recording area 7a of data record unit 4E.
Below, repeat above-mentioned processing.
According to form of implementation 7 of the present invention, can carry out the sampling of different condition simultaneously.
In addition, because the time shaft unanimity between data recording area 7a and the data recording area 7b, so data recording area 7a and 7B are represented also meaningful in identical figure, carry out at the same time under the situation of sampling processing of different condition, synthesis result is analyzed afterwards.
In addition, because the time shaft unanimity between a plurality of files, so can not roll up data volume suddenly, and can carry out the record that for example data variation slowly as the temperature variation and the fast data as the flow change effectively, simultaneously, can carry out the analysis accurately of time shaft unanimity during scrutiny afterwards.
Figure 18 is that expression is used the situation of buffer area 6 jointly to CH1 and CH2, but also can use a plurality of buffer area 6a and the 6b of the separation of application examples such as double buffer structure as shown in figure 19.
Figure 19 represent sampling a and b be recorded in respectively separately buffer area 6a and the situation of 6b.In this case, sampling each time is provided with a plurality of buffer area 6a and 6b (double buffer).
Among Figure 19, in step S4E each time, in a buffer area 6a, store " value 3 and the value 6 " of CH1 successively, " value 1, value 2, value 4, the value 5 " of in the 6b of another buffer area, temporarily storing CH2 successively temporarily.
Then, in step S6E, the data value in each buffer area 6a and the 6b is transferred to respectively among data record unit 4E interior the data recording area 7a and 7b.
Under the situation of double buffer structure shown in Figure 19,, can also obtain above-mentioned (with reference to the effect of the form of implementation 2 of figure 6～Fig. 9) except the effect of above-mentioned (with reference to Figure 18).
In addition, as shown in Figure 20, to above-mentioned different sampling condition (CH4 and CH5), also can use the structure identical with the situation of Figure 19.
The structure of Figure 20 with handle that the situation with Figure 19 is identical basically, expression sampling a and b be recorded in respectively separately buffer area 6a and the situation of 6b.
Yet, among Figure 20, are 2kHz as the frequency f 4 of the sampling a (CH4) of sampling condition, the frequency f 5 of sampling b (CH5) is 3kHz.
Therefore, each the sample frequency f4 of CH4 and CH5 and the lowest common multiple of f5 are 6kHz (=2 * 3 " kHz "), so utilize the sample frequency corresponding with sample frequency 6kHz to carry out interim stores processor (step S4E).
That is, among Figure 20, the processing of the cycle execution in step S4E that each the sample frequency f4 of utilization and CH4 and CH5 and the lowest common multiple of f5 are corresponding, and only obtain the measurement data of the CH that should obtain.
In addition, among Figure 20, interim stores processor (step S4E) the step S4E afterwards as then buffer area 6a being carried out CH4 " value 5 " if there is no under the data conditions of the CH that should obtain, does not carry out any processing in step S4E.
In the data recording and processing shown in Figure 20, because the relation of two sample a and b (CH4 and CH5) is not that one sample frequency is the integral multiple of another sample frequency, so utilize the cycle corresponding to carry out sampling processing (step S4E) with the lowest common multiple of each sample frequency.
In addition, in each sampling processing (step S4E), because only there is the sampling CH of this measurement data in sampling, CH to other does not carry out any sampling processing, so, as shown in Figure 20, even under the situation of the integral multiple that sampling period is not another sampling period relation, also can obtain above-mentioned action effect.
In addition, data control unit 3 (with reference to Figure 16) basis is based on the big or small dynamic assignment buffer area 6 in the sampling period of measurement data, and the while is according to the big or small dynamic assignment buffer area 6 of the port number of measurement data.
By like this, can eliminate waste, entire system can effectively utilize limited storer.
In addition, as shown in Figure 21, under the situation of the CH that has co-registered between the different sampling conditions, need not repeatedly summary record especially,, can utilize a summary record to write to a plurality of destinations to the double buffer structure identical with above-mentioned (with reference to Figure 19).
Here,, the frequency f 12 of sampling a (CH1 and CH2) is made as 1kHz (utilizing 1kHz summary record CH1 and CH2 both sides), the frequency f 2 of sampling b (CH2) is made as 2kHz as the sampling condition of Figure 21.
In this case, in initial interim stores processor (step S4E), CH2 " value 1 " is written among the 6b of buffer area, in following step S4E, CH2 " value 2 " is written among buffer area 6a and the 6b, and CH1 " value 3 " is written among the 6a of buffer area simultaneously.
Below, with above-mentioned same, in next procedure S4E, CH2 " value 4 " is written among the 6b of buffer area, in following step S4E, CH2 " value 5 " is written among buffer area 6a and the 6b, and CH1 " value 6 " is written among the 6a of buffer area simultaneously.
Then, in step S6E, the data value in each buffer area 6a and the 6b is transferred to respectively among data sink summary journal device 4E interior the data recording area 7a and 7b.
Under the situation that data sink summary journal shown in Figure 21 is handled, also can obtain above-mentioned action effect.
Especially, because the CH of co-registered need not only to utilize summary record one time through summary record repeatedly between a plurality of files, just can write a plurality of destinations, so can alleviate the burden of whole record.
Promptly, owing to carry out 6 secondary data acquisition processing from the CH of data input device 1 (AD converter), and 8 data to data record unit 4E of corresponding execution write processing, so eliminate the redundancy that obtains the relevant processing of data from the CH of AD converter, Just because of this, improved the processing speed that obtains this relevant part of data from the CH of AD converter.
In addition, owing to do not need the specialized equipment of the high price relevant with above-mentioned processing, so can realize data recording equipment cheaply.
Form of implementation 8.
In form of implementation 1～7, do not mention especially, if but formation comprises the testing fixture of data recording equipment arbitrarily, also can obtain identical effect.
In this case, because the data that the testing fixture utilization that is made of intelligent inspection unit is recorded in the data recording equipment are carried out the inspection processing, so can realize cheap testing fixture.
Form of implementation 9.
In addition, if constitute the control device of the data recording equipment arbitrarily that comprises above-mentioned form of implementation 1～7, also can obtain identical effect.
In this case, in the control device that constitutes by FA equipment such as sequence controller, motion controller, numerical control device and robots, utilization is recorded in the measurement data execution sequence control and treatment or the motion control of data recording equipment and handles, and can realize cheap control device.
