Due to the special nature of reefer containers and the complexity of the operations, it is necessary for terminal processes to clearly understand the performance of reefer containers. This is crucial to ensure that performance meets expectations and that the commodities inside remain under optimal conditions. If conditions are not met, terminals need to be equipped with tools to anticipate problems or react quickly to issues as they arise.
A Reefer Monitoring System (RMS) is an essential tool for effectively managing refrigerated containers within a container terminal. It ensures that these containers maintain optimal conditions by providing real-time visibility into critical parameters such as temperature, CO2 levels, and power status. Such systems can be seamlessly integrated with the Terminal Operating System (TOS), automating monitoring and management processes to minimize human errors and operational delays.
Due to the importance of these systems, it is crucial to standardize the data sent from different systems to facilitate integration and, thus, the implementation of these solutions in terminals. To standardize this information, we have translated the two most important messages for monitoring the performance of reefer containers: RMS to TOS and TOS to RMS. The process involved finding the equivalents of the most important data from both messages concerning the data points and definitions of TIC4.0 data models, and creating those definitions that did not yet exist in TIC4.0.
The following two tables present the two messages originating from both RMS and TOS and their expression in TIC4.0 language:
This message corresponds to the information sent from the RMS to the TOS. It includes the performance readings of the cargo and the configured setpoints.
