Abstract
Official abstract text for this publication.
An RS-485 bus is directly connected to transportation refrigeration unit sensors for transmitting information from the sensors to a remote location and for controlling sensor parameters from the remote location. The GENSET associated with the transportation refrigeration unit also utilizes the RS-485 bus, in which the bus is directly connected to the GENSET sensors for bi-directional communication therewith.
First claim
Opening claim text (preview).
What is claimed is 1. A method for controlling sensors utilized in a transportation refrigeration unit including a container and having a refrigeration unit controller and a GENSET to power said transportation refrigeration unit, comprising: coupling the transportation refrigeration unit to a transportation refrigeration unit data acquisition and control module via an RS-485 control bus for controlling the transportation refrigeration unit, wherein the transportation refrigeration…
