共享单车车速检测报警系统的设计

A Design of Speed Detection and Alarm System of the Shared Bicycle

针对市场上的共享单车没有超速报警系统而导致在车速过高时未能及时提醒骑车人降速影响交通安全的问题,本文采用霍尔传感器、STC12C5A60S2、SIM800C模块和语音播报等模块,设计了共享单车车速检测报警系统,实现了将共享单车行驶里程、瞬时速度和平均速度在共享单车固定的LCD上显示.若出现超速则报警系统将给骑车人发出语音报警,提醒骑车人减速;并把超过阀值的数据、超速时间和共享单车的编号通过短信发送给共享单车运营方的监管中心,从而较好地解决当前存在的问题.

Aiming at the problem that there is no over-speed alarm system for shared bicycle on the market,which may lead to the failure to timely warn the rider when the speed is too high and endanger the rider,this paper uses the Hall sensor,the STC12C5A60S2,the SIM800C module,the voice broadcast to design a bicycle speed detection and alarm system.The driving mileage,the instantaneous speed and the average speed of the shared bicycle were displayed on the LCD fixed on the shared bicycle.The alarm system would give a voice alarm to the rider to remind the rider to slow down when over-speed occurred;And the data exceeding the threshold value,the over-speed time and the number of the shared bicycle were sent to the supervision center of the shared bicycle operator by the message,so that the problems of the current problems could be better solved.
