Another technical matters to be solved by this invention provides a kind of highway traffic accident intelligent alarm method that can accurately and timely report to the police.
For achieving the above object, the invention provides a kind of highway traffic accident intelligent alarm method based on highway traffic accident intelligent alarm system, this highway traffic accident intelligent alarm system comprises n traffic accident intelligent alarm device (9), and n is positive integer, may further comprise the steps:
Step 1, speed of a motor vehicle detection module (4) the detection toy vehicle velocity value of passing through;
The toy vehicle velocity value that step 2, basis detect calculates the changes in vehicle speed value;
Step 3, judge that whether the changes in vehicle speed value surpasses setting threshold; When the changes in vehicle speed value surpassed setting threshold, processor (3) transmitted control signal to described audible-visual annunciator (2), and described audible-visual annunciator (2) begins to report to the police, and then execution in step four; When the changes in vehicle speed value does not surpass setting threshold, return execution in step one;
Step 4, processor (3) transmit control signal to described wireless monitor camera (5), and described wireless monitor camera (5) is taken pictures;
Whether step 5, decision processor (3) receive the stop signal that keyswitch (6) sends, when processor (3) receives the stop signal that keyswitch (6) sends, processor (3) transmits control signal to described audible-visual annunciator (2), audible-visual annunciator (2) stop alarm; When processor (3) does not receive the stop signal that keyswitch (6) sends, execution in step six;
Step 6, processor (3) judge whether audible-visual annunciator (2) time of fire alarming arrives setting-up time, when audible-visual annunciator (2) time of fire alarming arrives setting-up time, processor (3) transmits control signal to described audible-visual annunciator (2), audible-visual annunciator (2) stop alarm; When audible-visual annunciator (2) when time of fire alarming does not arrive setting-up time, return execution in step five.
Further, in order to realize the alerting signal transmission between each traffic accident intelligent alarm device (9), when the changes in vehicle speed value surpasses setting threshold, comprise that also processor (3) sends activation signal to the step of other traffic accident intelligent alarm devices (9) by radio receiving transmitting module (7) in the described step 3.
Further, in order to realize the alerting signal transmission between each traffic accident intelligent alarm device (9), receive the step of traffic accident intelligent alarm device (9) the guide sound light crossing-signal warning of activation signal.
The invention has the beneficial effects as follows: the present invention has realized the highway traffic accident warning function of complete meaning, reduces to greatest extent the possibility that highway knocks into the back and collides, and can effectively save people's life security and property loss.
