A control system automates control of reefer container resources in a reefer container system including a remote server computer in communication with reefer containers. Each reefer container includes a refrigeration system to control a climate of an interior cargo compartment of the reefer container. The refrigeration system includes a refrigeration circuit, including a compressor, a cooling space, and sensors to measure or estimate refrigeration system readings. The refrigeration system transmits refrigeration system parameter data; the remote server computer obtains the parameter data acquired during operation of the refrigeration system from at least one reefer container, and estimates a condition of the refrigeration system, including determining whether an alarm has been issued, or whether the estimated reefer container condition indicates that the refrigeration system requires maintenance or testing. A reefer container resource control unit receives the reefer container condition to automatically allocate the reefer container based on the reefer container condition.

Control system for automatic controlling reefer container resources

Techniques for remotely monitoring the operation of a cargo shipping reefer container configured with a refrigeration system that has installed therewith a control computer coupled with sensors monitoring the operation of the refrigeration system include: collecting a first and second set of observation data comprising a respective first and second sequence of measurement values measured by sensors coupled to the control computer; running a simulation model that receives the first set of observation data as input and outputs simulated values; the simulation model is configured to output the simulated values as estimates of the second set of the observations; computing an indicator value as a function of residual values computed from the difference between the values of the second set of observations and the simulated values; and evaluating the indicator value against a predefined criterion and issuing an alarm signal in case the predefined criterion is exceeded.
