Step 3: microprocessor 106 receive the simulating signal of acceleration transducers 102 outputs and control speech processes and wireless communication module 108 through radio-frequency antenna 110 signal that gives the alarm;
Step 4: repeating step one-step 3, follow-on test mountain bike ride different conditions and prompting in the process, report to the police.
The implementation method of its communication function comprises the steps:
Step 1: microphone 104 detects the variation of voice signal intensity dB in real time, and is converted into change in voltage Δ V;
Step 2: the voltage change signal Δ V to producing in the step 1 handles judgement, and whether decision carries out the conversion of communication state, and its processing basis for estimation is: preestablish voltage threshold Δ V
Threshold value, Δ V
Threshold valueThe condition that satisfies is: 6mV≤Δ V
Threshold value≤10mV; With Δ V and predefined voltage threshold Δ V
Threshold valueCompare, in continuous time 0.5s, as Δ V
On average>=5 Δ V
Threshold valueThe time, judge that communication state need switch to transmit status; In continuous time 0.5s, as Δ V
On average≤1/3 Δ V
Threshold valueThe time, judge that communication state need switch to accepting state;
Step 3: repeating step one-step 2, follow-on test mountain bike ride in the process different conditions and switch communication state.
The invention has the beneficial effects as follows: adopt acceleration transducer to detect the variation of the accekeration of bicyclist in the process of riding; Judge according to the variation amplitude size of acceleration signal whether the bicyclist falls down; Automatically carry out the transmission of alarm cue according to judged result, thereby realized automatic warning, notify companion's purpose.Adopt microphone to detect the voice signal intensity of bicyclist in the process of riding, control the switching of communication state, realized the function of free communication in the riding condition according to the intensity of voice signal.Total system is integrated on the mountain bike helmet, does not hinder the mountain bike bicyclist normally by bike.Have small volume and less weight, intellectuality, integrated advantage.
