Transportation of Fragile Goods
The Environment Monitor
design was used as a basis for the Transport Quality Monitor.
It measures, records, and alarms on the environment temperature and the three
axes of mechanical shocks. In the transport of fragile goods the monitored data
is used to find when and where transported merchandise suffered unacceptable
mechanical damage. Levels of acceptability for temperature and shock are
individually programmable.
One monitor is included in each package of fragile merchandize. It is individually
programmed with the threshold levels that would trigger an alarm. When the
merchandize is delivered, the alarms status (one LED) is checked and if red,
the unit has been subjected to unacceptable conditions of temperature and or
shock. Then monitored data is transferred to a PC and analyzed.
The unit has RS232 and I2C interfaces allowing economical communication
capabilities. With wireless modems units could be remotely interrogated from a PC.
Having a unique serial number the monitor could be used to track the merchandise.
