1. An automatic tractor/trailer tracking system ATTS that functions in combination with a power connector attached to a front structure of a trailer and a tractor, wherein the power connector has a hinged cover that is either in a closed vertical position or in an open horizontal position, and a remote receiver, wherein said ATTS is comprised of an electronic circuit comprising,
a) a microcontroller having a first input, a second input, a third input and an output, b) a set of preset signals applied to the first input of said microcontroller, c) a transmitter having a first input, a second input and an output, wherein the first input is connected to the second output of said microcontroller, d) a switching unit having an input and an output, wherein the output is connected to the second input of said microcontroller, e) a battery having a first output connected to the third input of said microcontroller, a second output connected to the input of said switching unit, a third output connected to the second input of said transmitter, and a fourth output connected to circuit ground, and f) an RF antenna connected to the output of said transmitter, wherein when the hinged cover of the power connector transitions from the closed vertical position to the open horizontal position, said switching unit closes, causing power from said battery to enable said microcontroller, thereby causing said microcontroller to wirelessly and automatically send via said transmitter and said RF antenna a set of trailer status signals to the remote receiver. |
