Abstract:
A wireless data transmission system incorporates a process sensor providing an output for process monitoring data with a transmitter connected to the output of the sensor and transmitting the data in time gated intervals. A receiver receives the data from the transmitter and a determination is made if new data is received at a gated time interval. A processor connected to the receiver calculates process parameters based on the data received and a set of the calculated process parameters is stored. The processor estimates process parameters based on the stored set of calculated process parameters responsive to a signal from the determination that data packets have not been received at the gated interval. The process parameters front actual data, if present, or from the estimates made by the processor are then output for process control. A counter responsive to the determination of lost data, provides an emergency stop signal upon reaching a predetermined number of counts.
