Controller with sensor for air cleaner

Transceiver for controller with sensor for air cleaner

To enables realization of an image data collection function, a bank switch function and the like at low cost in a juxtaposedly placed type sensor system for handling an image, such as a visual sensor or a displacement sensor, by introduction of the minimum required number of new units into an existing system. A first operation of storing image data acquired by a sensor controller from a sensor head and/or measurement data obtained by processing the image data, into a non-volatile record medium of a data storage unit, and/or a second operation of writing the setting data having been stored into the non-volatile record medium of the data storage unit, on a bank memory inside the sensor controller unit, are made possible.

Sensor system

An extension unit provided adjacent to an amp unit comprises a measurement data accumulation memory, a measurement data acquiring part for acquiring measurement data coming through a transmission line and accumulating it in the above memory, a data analyzing part for analyzing an accumulated series of measurement data according to predetermined algorithm, a determining part for determining a data analyzed result, and an output part for outputting a control signal corresponding to a determined result to the outside. A plurality of process programs in which measurement algorithm is segmentalized are incorporated in the extension unit and a process program is selected according to a command from a personal computer and the selected process program is performed in a predetermined order.

Multiple sensor system

A source table showing a standard relation between a detection object and a detection distance is stored in a memory ( ). A CPU ( ) receives inputs regarding distances to three measurement points from an input portion ( ) and recognizes an amplitude voltage corresponding to the input, as a measured value at the measurement point. Furthermore, the CPU ( ) extracts a range which corresponds to a difference between the farthest distance and the shortest distance, in which a ratio between voltages corresponding to measurement points closely resembles a ratio between the actually measured values, from the source table as a usage range, and creates a conversion table by correcting voltages in this extracted range.
