Railway tank car security device

A railcar sensing system comprising

• a railcar including a hatch,
• an orientation sensing device for sensing the orientation of the hatch,
• a central processing unit,
• a position sensing device for sensing the global positions of the railcar and for sending a first signal to the central processing unit representative of the global position of the railcar,
• the orientation sensing device sending a second signal to the central processing unit when the orientation of the hatch changes,
• a transmitting unit,
• the central processing unit analyzing the second signal from the orientation sensing device to determine if the orientation of the hatch changed more than a preselected limit determined by the event engine,
• the central processing unit sending a third signal to the transmitting unit if the orientation of the hatch changed more than the preselected limit.

A railcar sensing system comprising

• a railcar including a hatch,
• a position sensor for determining the global position of the railcar,
• a location processor,
• the position sensor sending a first signal to the location processor,
• the location processor determining whether the railcar is located outside of one of certain predetermined safe zones,
• a central processor,
• an accelerometer for sensing the orientation of the hatch,
• the accelerometer sending a second signal to the central processor when the orientation of the hatch changes more than a predetermined amount determined by the event engine,
• a transmitter,
• the central processor sending a third signal to the transmitter upon receipt of the first signal from the central processor if the railcar is located outside of one of the preselected safe zones.
