Abstract
A data sampling and collection system in an oil drilling system includes a data acquirer installed in the measurement sub to transmit a sampling collector identification signal to one of a plurality of sampling collectors coupled to the data acquirer. Each sampling collector includes a sensor and a plurality of random access memory (RAM) pages to store sensor data received from the sensor. When one of the sampling collectors receives the enable signal from the data acquirer, a current RAM page currently receiving sensor data from the sensor continues to receive sensor data without interruption and an immediately preceding RAM page storing a last completed page of received sensor data is transmitted from the one sampling collector to a memory of the data acquirer and from there to a surface computing system. As such, recent data is retrieved and transmitted for processing without interrupting the continuous collection of sensor data.
