Apparatus for establishing a mesh network for reefer sensor architecture
View Patent ↗The present invention provides a system and apparatus for monitoring temperature and airflow from multiple sensors node for maintaining proper conditions within a refrigerated tractor-trailer unit or reefer. The system provides a mesh network of multiple sensors, which communicate between sensors and with a processing unit of a reefer unit for monitoring the condition of transported goods.
1. An apparatus for establishing a mesh network of two or more sensor elements for monitoring conditions within a closed container, the apparatus comprising:
a central processing element for receiving sensor data from a plurality of sensors;
wherein the plurality of sensor elements comprise a sensor, a processing element and a transceiver co-located within a common housing; further wherein the plurality of sensor elements are configured to monitor one or more aspects of the closed container; and further wherein the sensor elements are configured to interrogate and communicate with one or more of the sensor elements within the same closed container;
wherein the central processing element is configured to analyze sensor data from the plurality of sensor elements and to transmit sensor data to a remote monitoring station, wherein the central processing element analyzes sensor data by receiving, analyzing and processing sensor data to determine whether measured aspects of the container's interior indicated by the sensor data exceed predetermined thresholds;
wherein the sensor data is received from the plurality of sensor elements and selected sensor data is transmitted to the remote monitoring station based on the analysis of the central processing element;
wherein the central processing element is configured to adjust sensor settings based on the analysis of the central processing element, wherein the adjusted sensor settings comprise changes to set sensor parameters, wherein the set sensor parameters comprise air flow parameters, moisture level parameters, and temperature parameters; and
further wherein the central processing element is further configured to assist in creating network connections between sensor elements.
