Railcar sensor communication system
According to some embodiments, a railcar monitoring system for monitoring one or more conditions associated with a railcar comprises a railcar controller and one or more sensors disposed throughout the railcar and communicably coupled to the railcar controller. The railcar controller is configured to exchange data with the one or more sensors and transmit data from the one or more sensors to a remote location. An amount of data exchanged between the railcar controller and the one or more sensors is controlled based on a railcar context. The railcar context is based on a location and/or activity associated with the railcar.

7. The railcar monitoring system of claim 1 , wherein the railcar controller is configured to transmit the data from the one or more sensors to the remote location via a message queuing telemetry transport (MQTT) server.
8. The railcar monitoring system of claim 1 , wherein the railcar controller is further configured to power off the one or more sensors based on the railcar context.
9. The railcar monitoring system of claim 1 , wherein the railcar controller is further configured to:
communicate with a second railcar controller;
determine the second railcar controller has a higher available battery power than the railcar controller; and
transmit the data from the one or more sensors to the remote location via the second railcar controller.
10. A railcar controller for monitoring one or more conditions associated with a railcar, the railcar controller comprising a memory comprising instructions coupled to a processor, wherein the railcar controller, when executing the instructions at the processor, is configured to:
exchange data with one or more sensors disposed throughout the railcar, wherein the one or more sensors are communicably coupled to the railcar controller via Bluetooth and wherein the data is exchanged between the railcar controller and each of the one or more sensors at a frequency higher than a reset time of a Bluetooth connection;
transmit the data from the one or more sensors to a remote location; and
wherein an amount of the data exchanged between the railcar controller and the one or more sensors is controlled based on a railcar context, and wherein the railcar context is based on a location associated with the railcar.
