摘要
为了有效避免司乘人员因安全措施不当而导致交通事故的发生,开发了基于单片机AT89C52的安全带控制系统.单片机依据正副驾驶座下的测重仪所测重量信息控制扬声器发出报警,并控制仪表盘的相应标示报闪或语音提示.实验结果及与原有警示方法的比较结果表明,该系统具有较好的警示性能,达到了安全警示的目的,司乘人员的安全系数得到了提高.
For avoiding traffic accidents due to improper security measures taken by drivers and passengers,safety belt warning system was developed based on the single-chip AT89C52.Single-chip MCU control loudspeakers sending out the warning according to the information of weight that come from the sensor under the driver＇s seat and controls the dashboard′s corresponding labels flashing or voice prompting.Comparing with original warning methods,the results and test show that the system has better warning performance and has achieved the security warning purpose as well as safety coefficient of drivers and passengers has been enhanced.
