METHOD OF COLLECTING INFORMATION IN A SENSOR SYSTEM Russian patent published in 2018 - IPC E21B47/12 G06F11/22 G06F12/10 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil industry, in particular to well geophysics loggings, namely to methods for measuring and monitoring well parameters. Proposed method of collecting information in a sensor system, consisting of a sensor control device and sensors, includes cyclic interrogation of sensors from the table of correspondence of temporary addresses of the sensor control device; transmission from the sensor control device of the broadcast command of setting a temporary address perceived by all sensors, not yet received a temporary address; receiving the broadcast command for setting the address by the sensor without a temporary address; assignment by the sensor the temporary address from the data field of the received command; waiting for a pause of the random duration given by the random number generator of the sensor; checking the busyness of the line and, in the case of a free line - issuing a response signal, containing data necessary for sensor identification from its non-volatile memory, in the case of a busy line - reset of the sensor address to the original one. In this case, after assigning a temporary address to the sensor, information about it is entered in the correspondence table of the addresses of the sensor control device. In the case of determining the absence of a sensor or its malfunction, the temporary address of this sensor is cleared for use in the data field of the broadcast command for specifying the address, the information on the sensor itself is deleted from the address table of the sensor control device.

EFFECT: technical result is increased reliability and accuracy of the information collection method in a sensor system.
