Abstract
Methods and systems are provided for monitoring a refrigerated cargo container in real time including receiving sensor signals from a plurality of sensors that include one or more of a temperature sensor, a humidity sensor, and a pressure sensor; and processing the sensor signals to identify one or more signal characteristics that correspond to predefined patterns, wherein the predefined patterns are correlated to one or more container conditions including at least one of an open door, a container load level, and a cargo type.
Claims38
A method of monitoring a refrigerated cargo container in real time, implemented by a controller having one or more processors and having memory storage, the memory storage including instructions that when executed by the one or more processors implement steps comprising:
- receiving sensor signals from a plurality of sensors that include two or more of a container air temperature sensor, a container air humidity sensor, a refrigeration unit suction pressure sensor, and a refrigeration unit discharge pressure sensor;
- processing the sensor signals to identify one or more signal characteristics that correspond to predefined patterns, wherein the predefined patterns are correlated to one or more container conditions including at least one of an open door, a container load level, and a cargo type;
- and providing a status notification indicative of the one or more container conditions.
