Dynamically programmable automotive-driving monitoring and alarming device and system

A vehicle driver monitor device receiving a vehicle driving speed signal, comprising:

• a receiver for receiving a transmitted signal including a speed limit value;
• a memory for storing said speed limit value;
• a comparator for comparing said vehicle driving speed to said stored speed limit value and generating an alarm signal when said vehicle driving speed exceeds said stored speed limit value;
• and
• a validating means for determining whether said speed limit value of said transmitted signal is valid.

A vehicle driver monitor device having a micro-controller and receiving a vehicle driving speed, comprising:

• a receiver for receiving and decoding a transmitted signal including a speed limit value;
• a memory for string current speed limit reference;
• an interrupter connected to said receiver and receiving said speed limit therefrom, said interrupter comparing said speed limit value to said current speed limit reference and interrupting said micro-controller when said encoded speed limit value differs from said current speed limit reference, for storing said encoded speed limit value in said memory as said current speed limit reference;
• a comparator for comparing said received vehicle driving speed to said current speed limit reference and generating an alarm signal when said received vehicle driving speed exceeds said current speed limit reference;
• wherein said transmitted signal further includes a system identification string and wherein said vehicle driver monitoring device further comprises:
• a first validating means for ignoring said transmitted signal when said first validating means determines that said system identification string is invalid;
• a second validating means for determining whether said speed limit value is valid.

A traffic monitoring system comprising a driver monitor device and a field transmitted for transmitting a signal, said transmitted signal comprises a speed limit value and a system identifier string, and wherein said driver monitor device comprises:

• a receiver for receiving said transmitted signal including the speed limit value and system identifier string;
• a memory for storing said speed limit value;
• a comparator for comparing said vehicle driving speed to said stored speed limit value and generating an alarm signal when said vehicle driving speed exceeds said stored speed limit value;
• and
• a first validating means for ignoring said transmitted signal when said first validating means determines that said system identification string is invalid;
• a second validating means for determining whether said speed limit value is valid.
