Abstract
PURPOSE: To reduce the load caused by the noise data identification to CPU by providing the noise identifying function within the data collection/distribution unit, and then to avoid the leak of the data collection due to the time delay caused by discontinuation of the data collection and other factors.
CONSTITUTION: The circuit consists of CPU1, main memory 2, channel unit 3, dada collection/distribution unit 6, data transmitter/receiver 7, oscilloscope 11 and others. Unit 6 comprises substitute data 15, change-over switch 16 and identification report signal generator 17. Oscilloscope 11 applies the control signal to switch the switch of circuit 16 toward substitute data 15 when the fact is detected that the external data mixed with the noise data is outside the data range which is set up previously, and the output of data 15 is supplied to memory 2 via unit 3. Thus, CPU1 is not required to carry out the noise identification process and thus not required to give an order to unit 3 for discontinuation or restart of the data collection. As a result, no collection leak is caused due to the time delay
