4.
Colour code pulse train filtering time T
1, encoder pulse train filtering time T
2with colour code protection umber of pulse N
1for signal filtering module 304 (comprising the first wave filter and the second wave filter).The function of signal filtering module 304 is burrs in filtering encoder pulse train and colour code pulse train, generates high-quality encoder pulse train and colour code pulse train.
Signal filtering module 304 pairs of encoder pulse train carry out filtering, when encoder pulse train keeps the state duration of a certain level (high level) to be more than or equal to encoder pulse train filtering time T
2time just assert that encoder pulse train state has become this state.As shown in Figure 4, signal 401 is original encoder pulse train, t
0moment encoder pulse train becomes high level and remains to t always
0 `moment, t
0 `-t
0=T
2, therefore at t
0 `the encoder pulse train 402 that moment exports becomes high level; Because of t
3-t
2<T
2, the encoder pulse train 402 therefore exported is at t
3still low level is kept.
In like manner, signal filtering module 304 pairs of colour code pulse trains carry out filtering, when colour code pulse train keeps the state duration of a certain level (high level) to be more than or equal to colour code pulse train filtering time T
1time just assert that colour code pulse train state has become this state.As shown in Figure 4, signal 403 is original colour code pulse train, t
0moment colour code pulse train becomes high level and remains to t always
0moment, t

Signal filtering module 304 is according to the colour code protection umber of pulse N arranged
1control the colour code pulse exported.The encoder pulse train number that rising edge (or trailing edge) spacing of the colour code pulse train after after filtering comprises is more than or equal to N
1time export colour code pulse train; The encoder pulse train number comprised when spacing is less than N
1time do not export colour code pulse train.As shown in Figure 4, colour code pulse train 404 is after filtering at t
0moment, t
10moment, t
14moment and t
16moment is signal rising edge, wherein t
0moment and t
10encoder number between moment is greater than N
1, therefore at t
10moment also outputs colour code pulse (see 405); And t
10moment and t
14encoder number between moment is less than N
1, therefore at t
14moment does not output colour code pulse (see 405); Until t
16moment encoder number is greater than N
1, therefore at t
16moment outputs colour code pulse (see 405).
Colour code delay pulse number N
2for Postponement module 204, its computational methods are as follows: suppose that color mark sensor 105 is L (unit mm) with the coverage of detection part 108, driving shaft effective diameter is D (unit mm), and encoder line number is N, then colour code delayed encoder pulse train number N
2see formula 1:
The function of Postponement module 204 is the colour code delay pulse number N according to arranging
2, delay disposal is carried out to the colour code pulse train after signal filtering module 304 processes.This module can be divided into colour code spacing detection module and Postponement module, and these two parts are connected by the FIFO (fifo queue) in the register of controller.Colour code spacing detection module stops this detecting at the rising edge of colour code, and startup detects next time; The colour code spacing that this detects is M; If Postponement module is in idle condition and the FIFO connected each other is in empty state, then write colour code delay pulse number N to FIFO
2, otherwise the colour code distance values M that write current detection arrives.Postponement module is readout value carry out delay and export from FIFO successively, if do not have data in FIFO, then does not need to export colour code pulse train.
As shown in Figure 5, signal 10 is encoder pulse train, and signal 20 is the colour code pulse train of module filtered after filtering, the colour code delay pulse that signal 30 exports for Postponement module.At t
0there is a colour code pulse s in time-ofday signals 20
1, before this moment, FIFO is empty, and Postponement module is idle condition, therefore writes the data DI of FIFO
0=N
2, read the data DO of FIFO
0=N
2data, at t
0with t
1between moment, Postponement module is in busy condition, in t
1moment produces colour code and exports pulse s
1 `, now FIFO is empty, and Postponement module is idle condition;
At t
3there is a colour code pulse s in time-ofday signals 30
3, before this moment, FIFO is empty, and Postponement module is busy condition, therefore writes the data DI of FIFO
2=M
2; Until t
4moment creates colour code and exports pulse s
2 `, now Postponement module is idle condition, reads the data DO of FIFO
2=M
2data, now FIFO is empty, until t
5moment creates colour code and exports pulse s
3 `, Postponement module is idle condition.
Export colour code umber of pulse N
3arrange as required, this numerical value is more than or equal to 1, for multimode block 208, refers to and will generate N
3individual colour code output pulse sequence.
Export colour code pulse distance N
4for multimode block 208, refer to when exporting colour code umber of pulse and being more than or equal to 2, the encoder pulse train number of two adjacent output colour code pulse distances.
The function of function wave module 208 is the output colour code umber of pulse N according to configuration
3with output colour code pulse distance N
4, and encoder pulse train and through Postponement module 204 export colour code delay pulse sequence, generate need colour code output pulse sequence.
As shown in Figure 6, signal 10 is encoder pulse train, the colour code delay pulse sequence that signal 30 produces for Postponement module.As output colour code umber of pulse N
3when being 1, parameter exports colour code pulse distance N
4invalid, signal 40 be colour code output pulse sequence (in this preferred embodiment, identical with signal 30, be also postpone N
2individual encoder pulse).At t
0there is a colour code pulse s in time-ofday signals 30
1, therefore at t
0moment exports colour code pulse s
11 `; In like manner at t
1moment exports colour code pulse s
12 `, at t
2moment exports colour code pulse s
13 `.
As output colour code umber of pulse N
3when being greater than 1, assuming that N
3be set to 2, export colour code pulse distance N
4be 6, the output colour code pulse train that signal 50 generates for another.At t
0there is a colour code pulse s in time-ofday signals 30
1, therefore at t
0moment exports colour code pulse s
21 `, after 6 encoder pulse train, at t
0 `moment exports colour code pulse s
21 ``; At t
1there is a colour code pulse s in time-ofday signals 30
2, therefore at t
1moment exports colour code pulse s
22 `, after 6 encoder pulse train, at t
1 `moment exports colour code pulse s
22 ``; And at t
2moment detects that signal 30 exists a colour code pulse s
3, now colour code pulse s
2output waveform also do not complete, therefore create conflict, the module that reports an error 307 will stop the function of multimode block 208, stop exporting colour code pulse train.
