Integrated cargo security system

An integrated cargo transportation security system for use with a fleet of enclosed cargo transportation containers, each container having at least one access door enabling cargo to be loaded and unloaded, the system including for a said container:

• intrusion sensor means for sensing and putting out a status signal whenever intrusion into the container is sensed,
• a module unit associated with the container, each module unit including means for receiving a removable module and including cabling leading to said instrusion sensor means,
• a removable module for each module unit lockable mounting into a housing of the unit by security personnel,
• a central data collection and processing facility for receiving cargo trip data collected by at least one active module during a cargo trip of a said container of the fleet and for processing the cargo trip data into a roadmap indicating travel route of the said container during the trip and time and location of significant events such as unauthorized intrusion into the interior of the container during the trip,
• the said module unit in combination with an active module including a self contained power supply, location providing means for providing positional coordinates, clock means for generating clock signals corresponding to the time interval of the trip, central processing means connected to the intrusion sensor means, the power supply, the radio navigation means and the clock means for generating a sequence of status numbers indicative of present location, time and intrusion status, and any tampering with the module unit, and memory means for storing the said sequence during the trip,
• the system including means for transferring the sequence stored in the memory means to the central data collection and processing facility.
