How LXRS™ Works
The LXRS™ Wireless Sensing System works by leveraging advanced bi-directional radio communications protocols. When data are received without errors by the WSDA base station, the WSDA sends an acknowledgement that these packets were received. Data that are not acknowledged remain within each LXRS sensor node's non-volatile memory for re-transmission according to the network scheduler. Note that data are time-stamped by each node at the time of analog-to-digital (A/D) conversion. Therefore, even when re-transmitted, all data are accurately time stamped.
LXRS protocols enable highly reliable data collection from scalable networks of wireless strain, acceleration, torque, force, temperature, etc. Under most operating conditions, users will enjoy 100% reliable (i.e., lossless) data transmission. This is very important when working in harsh operating environments or when the system may be subject to periodic RF interference. Critical experiments, that may be difficult to set-up or replicate, can benefit from LXRS reliability. When the wireless "data connection" between sensor nodes and the WSDA base station may be temporarily lost, LXRS lossless protocols enable full data recovery.
Reduced Power Consumption
Synchronized data collection, combined with LXRS data acquisition, allows users to select lower sampling rates, because there is no need to oversample. In many cases, users can also use reduced radio transmission power levels, which leads to longer battery life and enables energy harvesters to be used in lieu of primary batteries.
