Adaptive bandwidth consumption in remote monitoring of agricultural assets
First Claim
1. A method for remotely monitoring one or more agricultural assets at a remote location, the method comprising:
- providing a monitoring system comprising i) a plurality of condition sensors in communication with the one or more agricultural assets such that each condition sensor is arranged to sense a respective asset condition of a respective agricultural asset, ii) a controller separate from and commonly associated with the plurality of condition sensors at the remote location which is arranged for receiving sensed conditions transmitted from the condition sensors, the controller including a memory storing previously sensed conditions and prescribed notification criteria comprising a threshold level associated with the plurality of condition sensors thereon and a transceiver, and iii) a central monitoring station located separately from the remote location and arranged for communication with the controller through the transceiver of the controller; and
using the controller to periodically perform a sampling cycle comprising a sampling of each condition sensor of the respective asset condition of the agricultural asset sensed by the condition sensor;
for each sampling cycle, using the controller to compare each sampled asset condition sensed by each condition sensor to at least one of the previously sensed conditions to determine if the threshold level of the prescribed notification criteria has been met for that condition sensor and determining a notification condition for that condition sensor if the sampled asset condition meets the threshold level of the prescribed notification criteria; and
using the controller, subsequent to completion of the sampling cycle, to initiate transmitting a single notification signal to the central monitoring station associated with the sampling cycle only if the notification condition is determined corresponding to any one of the condition sensors sampled within the sampling cycle such that the single notification signal is the only notification signal transmitted to the central monitoring station for the respective sampling cycle, the single notification signal including an identification of each sensed condition which resulted in the determination of the notification condition for the respective condition sensor sampled within the respective sampling cycle.

Abstract
Individual agricultural assets at a remote location are each equipped with at least one condition sensor in communication with a location-based controlling transceiver, which in turn communicates with a central monitoring system. The transceiver will monitor data received from the condition sensors and in accordance with predetermined notification parameters will send a signal to the central monitoring system only when a notification condition, for example an elevated temperature reading in the instance of a grain bin, is detected. By only communicating when a transmission bandwidth requirements between the transceiver and the central monitoring system are minimized. Further transmission bandwidth reduction can be achieved by limiting the notification condition parameters limiting transceiver packet. Various conditions including temperature, gas levels or presence, volume or other conditions of various types of assets could be monitored remotely in this way.
