I do.

FIG. 2 is a flowchart showing input / output synchronization control according to one embodiment of the present invention. These FIGS. 1 and 2
An input / output synchronization control according to an embodiment of the present invention will be described with reference to FIG. The processing operation shown in FIG. 2 is realized by executing a program stored in a control memory (not shown) by each unit of the data collection and distribution device.
M (read only memory), a floppy disk and the like can be used.

The input signals # 1 to # 3 input to the input correction processing circuits 1 to 3 are input in a format of a transmission system employing a cyclic system. Here, in the cyclic transmission, data of several words to several tens of words are always repeatedly transmitted in a continuous word string.

The input shift detecting circuit 4 detects a shift of each input cyclic data by time, and detects a shift time between the input signals # 2 and # 3 with reference to the input signal # 1 (FIG. 2). Steps S1 and S2).

The input shift detection circuit 4 inputs this shift time as correction signals 101 to 103 to the input correction processing circuits 1 to 3 (step S3 in FIG. 2).
3 generates a delay by a delay circuit (not shown) corresponding to the time, and outputs the delayed input data to the input processing circuit 5 (step S4 in FIG. 2).

All the data input to the input processing circuit 5 have the same timing, and the input processing circuit 5 can operate each input at the same processing timing. The input processing circuit 5 decomposes the inputted cyclic data in word units and stores it in a predetermined storage location.

The editing / exchange processing circuit 6 arbitrarily defines in advance which input word is to be edited and exchanged with which output word by the user, and performs the editing / exchange operation as defined at the operation timing of the output processing. Output processing circuit 7-

The exchange processing operation circuit 10 calculates the contents of the edit exchange processing registered in advance for each output (step S6 in FIG. 2), and can start the output processing at any timing based on the relationship between the input word and the output word. For example, it is calculated whether or not the response time from input to output is the shortest, which is most suitable for the input timing.

The exchange processing arithmetic circuit 10 outputs the calculated time as a rise control signal 104 to the output processing circuits 7 to 9 (step S7 in FIG. 2), and controls each of the output processing circuits 7 to 9 (step S8 in FIG. 2). ).

FIG. 3 is a diagram showing an input correction process according to one embodiment of the present invention, and FIG. 4 is a diagram showing output rising control according to one embodiment of the present invention. The operation of the embodiment of the present invention will be described with reference to FIG. 1, FIG. 3, and FIG.

The input signals # 1 to # 3 are input in a format of the cyclic digital transmission system. When a certain time axis is used as a reference, the input signals # 1 to # 3 are changed according to the rising timing of the transmitting party. The transmission timing is shifted. However, since this shift width is cyclic transmission, the input signals # 1 to # 3 always have the same timing.

Here, the shift time in the case of the input correction processing shown in FIG. 3 is such that the input signal # 1 is advanced from the reference time by the tl time of the first word, and the input signal # 2 is shifted by the t2 time of 10 words. The input signal # 3 is just 31 words.

The input shift detecting circuit 4 detects this time width and calculates a correction time by the following calculation. First, the input shift detection circuit 4 calculates a shift time between the input signal # 1 and the input signal # 2 by a time of “(10 words + t2) − (1 word + t1)”, using the reference time as the input signal # 1. That is, assuming that one word time is 1N, the above calculation formula is “(10N + t2) − (1N + t1)”.

Next, the input shift detecting circuit 4 outputs the input signal # 1.
And the input signal # 3 is calculated as the "31 word- (1 word + t1)" time. Also in this case, assuming that one word time is 1N, the above calculation formula is “31N− (1N +
t1)).

The input shift detecting circuit 4 adds the calculated time width to the input signal # 2 and the input signal # 3 so that all inputs are input to the input processing circuit 5 at the same timing.

When performing the rise control, first, the input signal # 1
# 3 to # 3 have the same input timing due to the above processing. The output signal # 1 is output words D1 to D31.
Are regularly arranged from the first word (d1-1) to the 31st word (d1-31) of the input signal # 1.

The output signal # 2 is 3 from the first word (D1).
Until the first word (D31), the input signal # 2 is arranged in order from the fifteenth word (d2-15). For the output signal # 3, the first word (D1) is the first word (d1-1) of the input signal # 1, the second word is the fifteenth word (d2-15) of the input signal # 2, and the third word is the input signal # 3 of 31
A random definition is made as in the word (d3-31).

Here, as the output rising control method, the output signal # 1 has exactly the same word editing content as the input signal # 1, so the output signal # 1 is input at the input timing of the input signal # 1.
Is activated, the input signal # 1 and the output signal # 1 are processed with the shortest time difference.

Next, regarding the output signal # 2, the output signal # 2 is edited from the 15th word of the input signal # 2. In this case, the processing of the output signal # 2 starts from the fifteenth word of the input signal # 2, so that the timing between the input signal # 2 and the output signal # 2 is the shortest. Similarly, the start-up time of the output signal # 3 is controlled to be the shortest time according to the contents of the word editing.

As described above, the input shift detecting circuit 4 detects the input shift times of the plurality of input signals # 1 to # 3 to generate the correction signals 101 to 103 of the detection time width, and the input correction processing circuits 1 to 3 And the correction signals 101 to 101 from the input shift detection circuit 4
By shifting the input timings of the plurality of input signals # 1 to # 3 according to 103, all the signals of the cyclic system which are input asynchronously can be set to the same timing, so that it is not necessary to individually perform the input processing. ,
Input processing can be simplified.

The exchange processing circuit 10 calculates which input data is stored in which position of which output data at each output and outputs the rise time of each of the output circuits 7 to 9 based on the calculation result. Under the control of the rise control circuit 11, the contents of the word editing of the output signals # 1 to # 3 are detected, and the output signals # 1 to # 3 are appropriately matched.
Since the 3rd cyclic operation can be activated,
The timing of the shortest time between the input and the output can be set, and a device with a high response response can be configured.
That is, the response time from input to output can be minimized.

[0046]

As described above, according to the data collection and distribution device of the present invention, in the data collection and distribution device for editing and exchanging a plurality of cyclic input data and outputting the same, the input shift time of each of the plurality of input data is reduced. Is measured, and the input timing of another input data is adjusted to one input timing of the plurality of input data based on the measured time, whereby the input processing can be simplified.

By outputting to one output signal, calculating the contents of editing and exchanging words of the output signal, and controlling the operation start timing of each of a plurality of output processing means for outputting an output signal to the outside according to the calculation result, The effect is that the response time from input to output can be minimized.
