| 基于单片机的汽车防盗报警系统的设计与实现 摘要 本文主要深入研究基于多种单片机控制技术的安全自动报警控制电路的系统设计工作方法和系统可靠性问题分析。本文首先对系统的硬件任务结构进行了系统描述和设计分析,建立了系统的硬件可靠性设计模型,比较和研究确定了系统的硬件设计方案,设计了系统硬件集成电路和系统软件集成电路。最后,利用Proteus等软件对系统性能进行了一次仿真和测试运行。 本文研究设计了一种基于数控单片机的多路无线通信防盗自动报警控制系统。系统由数字信号处理器、传感器、无线数据传输控制模块、报警控制电路和图像显示器等电路模块组成。它指的是一种完全能够同时实现防盗信号自动检测、报警和自动报警的无线安全防盗报警系统。系统主要硬件设计部分系统采用无线报警收发器该模块首先接收射频解码后的报警信号,经主控单片上电机处理后输出发送给主控单片机,再由主控单片机经过报警系统处理后将输出发送到数字显示控制电路,建立了系统可靠性设计模型,论证了整套系统设计方案,根据系统设计图的要求重新确定了系统设计方案,给出了振荡电路和自动复位控制电路,设计了数字显示控制电路、报警处理电路和plc等子系统模块,给出了具体设计参数的系统计算完成过程。软件设计部分主要详细列出了系统的软件总体设计功能框图和应用程序流程原理图,使各位读者同时能够快速准确了解整个系统的总体设计基本思想和工作过程,然后对系统软件进行自动调试和安全测试,验证整个系统的安全可靠性。该报警系统主要用于多点检测自动报警,并能同时自动检测多个点。当一个或多个点上的检测器收到各种报警发生信号时,将低至高电压水平送至一个单片机,单片机同时产生一个高电平,使得LED和多个扬声器同时工作,显示各种报警发生原因和误报位置,最终可以实现一种多报警路径和智能化的报警信号控制。 关键词：单片机；无线防盗报警器；传感器；显示电路；报警控制 Abstract This paper focuses on the application of single-chip technology to the security alarm circuit reliability design and analysis method. This paper first describes and analyzes the task of the system, establishes the reliability model, then compares and determines the design scheme, then designs the hardware circuit and software circuit, and finally simulates and runs the constructed system in Proteus Software. This paper designs a multi-channel wireless anti-theft alarm system based on MCU. The system integrates signal processor, sensor, wireless transmission module, alarm circuit and display circuit into a small system. It is a wireless anti-theft system that can realize signal detection, signal processing and signal transmission. This system uses the wireless transmitting and receiving module to transmit the received signal to the MCU after the decoding chip processing, and then to the alarm display circuit after the MCU processing. In the hardware part, the reliability model is established, the system scheme is demonstrated, the design scheme is compared and determined according to the design requirements, and then the oscillation circuit, reset circuit, display circuit, alarm circuit and other sub modules are designed respectively. Finally, the specific parameter calculation process is listed. The software part mainly lists the overall design block diagram and system flow chart of the program, which is convenient for readers to quickly understand the design idea and process. Then, the system is debugged and tested, and the reliability of the system is demonstrated. This system is used to detect and alarm, and can detect multiple points at the same time. When one or more points are detected with alarm signal, it will send a low level to the single chip microcomputer, and then the single chip microcomputer will output a high level, so that the LED and loudspeaker work to alarm and display the alarm reason and location, and finally realize multi-channel intelligent alarm control.
