Data Logging in Heavy, Off-road Trucks

A major manufacturer of industrial trucks needed to build a data logger into each vehicle in order to monitor a wide variety of systems within the vehicles. The application requires a compact, rugged, DC powered logger that could not only monitor the analog and digital inputs normally associated with data logging, but could also monitor and log information from CAN-bus devices, RS-232 interfaces and GPS position and velocity data. The logger also needs to be easily configured with different I/O configurations as many vehicles have unique I/O requirements.

The UEILogger is the perfect solution. Not only does it provide the environmental (tested: -40° to +85°C), and physical ruggedness (50 g shock, 5 g vibration) required, the ability to select the I/O configuration from the wide variety of analog, digital, Counter/timer, Serial, CAN and GPS interfaces ensures the logger can be configured to exactly match the requirement of the particular vehicle.

Another advantage of the UEILogger is its intuitive, easy-to-learn Windows based configuration application. As each application is somewhat different from the others, each system requires a semi-custom data logging configuration. The ease of use of the UEILogger software dramatically reduces the time required to train the installing technicians.

Once the data logging application is competed, data may be downloaded in two ways, depending on the usage of the truck. Data fromtrucks that return to main garage is obtained by simply removing the SD card from the logger, and copying the data into a PC for furtheranalysis and archiving. Trucks that remain in the field represented a different problem as it was prohibitively expensive to retrieve the physical SD card after each session. These vehicles were outfitted with CDMA-based high speed Cell Network interfaces. At the end of the session, the data can be downloaded by any host computer with access to the internet.
