In refrigerator tractor/trailer vehicles, a data acquisition module is connected with one or more temperature sensors adapted for measurement of the temperatures within the trailer and may be connected with one or more distance sensors and “door open”sensors located in the trailer. Such a data acquisition module preferably comprises a microprocessor and random access memory connected with a plurality of sensors and adapted to acquire stored data on temperatures within the trailer and further connected with clock means to provide time data associated with the temperature data. In such systems, a control and display module, which comprises a separate portable control and display unit, can provide temperature data and distance data to the vehicle operator, warnings to the vehicle operator if the temperature of the trailer approaches unacceptable limits, warnings during backing of the trailer of impending collision with an object and warnings if the trailer doors are opened without authority. The control and display module provides controls for operation of the system, a digital readout, and an audible alarm.
