摘要
本系统由上位机和下位机两部分组成。下位机以超速报警系统为主,由STC89C52单片机主控制器、直流电动机、语音模块BY8301-16P、串口蓝牙HC-06和按键构成,完成速度的测量及蓝牙通信连接功能。智能手机端APP软件通过HC-06蓝牙连接超速报警系统,接通蓝牙后,手机APP屏幕能实时显示车辆行驶速度、行驶距离、报警速度值,同时也能对速度报警阈值重新设置(增加或减少速度值)。行驶中,当速度超过预设报警值时,能以蜂鸣声或真人语音提醒驾驶员减速慢行。给出了系统硬件的电路设计构成和软件流程设计、编码,经测验,系统运行正常,满足上述功能要求。
The system consists of upper computer and lower computer.The lower computer is mainly composed of overspeed alarm system,STC89C52 MCU main controller,dc motor,voice module by 8301-16p,serial port bluetooth HC-06 and buttons to complete speed measurement and bluetooth communication connection.The smart phone APP software connects to the overspeed alarm system through HC-06 Bluetooth.After Bluetooth is connected,the mobile APP screen can display the vehicle driving speed,driving distance and alarm speed value in real time,and can also reset the speed alarm threshold (increasing or decreasing).During driving,when the speed exceeds the preset alarm value,the driver can be reminded to slow down by beeping or voice of a real person.This paper presents the circuit design composition of the system hardware and the software flow design and coding.
