Title:
DATA READING DEVICE
Document Type and Number:
Japanese Patent JPS60229105
Kind Code:
A
Abstract:
PURPOSE:To read process data after deleting the superposed noises out of the data by reading the input data having its changing width set within an allowable range of a sampling cycle after deciding it as the correct data. CONSTITUTION:A changing allowance range K is read into a RAM8 from an allowance range setting part. The process value of a control subject 1 is converted into electric signals by a sensor 2. The output of the electric signal is applied to a CPU6 of a control part 5 via an amplifier 3 and an A/D converter 4. The converter 4 is started by the signals sent from the CPU6 every time the data processing is over. The data read into the CPU6 is compared with the range K stored in the RAM8 after its changing width of a sampling cycle is calculated by the CPU6. When said changing width is within the range K, the corresponding data is read into the RAM8. Then the control amount is decided and the subject 1 is controlled via an output operation part 9. Thus it is possible to read the process data after deleting the superposed noises.
