摘要：车辆视野盲区是当前车辆设计的固有缺陷，是引发交通事故的重要因素。当今社会针对车辆视野盲区问题而设计的保护装置存在应用场景受限、保护范围小、系统成本高、产品种类少等诸多局限与不足。针对此类问题，本文设计一种以双AT89C52单片机为控制核心，基于超声波测距技术与多对一无线通讯技术，实现盲区监测与上位机远程报警控制装置。主要利用多个自由分布的HC-SR04超声波监测单元进行车辆视野盲区的覆盖与监测，当检测到障碍物后可实现自动测距，并对障碍物进行危险分级划分，进而确定上位机控制指令。基于nRF24L01无线传输功能可实现监测模块与上位机的无线通讯，进行远程报警控制，从而提醒驾驶员注意周边环境。本文在完成装置的硬件设计与程序设计后，通过Proteus对装置进行了模拟仿真，成功验证了设计可行性。该装置具有适用车型广、监测范围大、测量精度高等优点，可有效对车辆视野盲区内物体进行检测与报警。

Abstract:
Visual field blindness is an inherent defect of current vehicle design and an important factor causing traffic accidents. In today’s society, the protection devices designed for the blind area of vehicle visual field have many limitations and deficiencies, such as limited application scenarios, small protection range, high system cost, and few product types. In order to solve these problems, this paper designs a control device based on dual AT89C52 microcontroller, ultrasonic ranging technology and many-pair wireless communication technology to realize the blind area monitoring and remote alarm control device of upper computer. It mainly uses several freely distributed HC-SR04 ultrasonic monitoring units to cover and monitor the blind area of vehicle visual field. When obstacles are detected, automatic ranging can be realized, and danger classification of obstacles can be carried out, so as to determine the control instructions of the upper computer. Based on the wireless transmission function of nRF24L01, the wireless communication between the monitoring module and the upper computer can be realized to carry out remote alarm control, so as to remind the driver to pay attention to the surrounding environment. In this paper, after the completion of the hardware design and program design of the device, the simulation of the device through Proteus, successfully verified the design feasibility. The device is suitable for a wide range of vehicles, a large monitoring range, high（未完，下一页）
