摘要：車輛視野盲區(qū)是當(dāng)前車輛設(shè)計的固有缺陷，是引發(fā)交通事故的重要因素。當(dāng)今社會針對車輛視野盲區(qū)問題而設(shè)計的保護(hù)裝置存在應(yīng)用場景受限、保護(hù)范圍小、系統(tǒng)成本高、產(chǎn)品種類少等諸多局限與不足。針對此類問題，本文設(shè)計一種以雙AT89C52單片機(jī)為控制核心，基于超聲波測距技術(shù)與多對一無線通訊技術(shù)，實現(xiàn)盲區(qū)監(jiān)測與上位機(jī)遠(yuǎn)程報警控制裝置。主要利用多個自由分布的HC-SR04超聲波監(jiān)測單元進(jìn)行車輛視野盲區(qū)的覆蓋與監(jiān)測，當(dāng)檢測到障礙物后可實現(xiàn)自動測距，并對障礙物進(jìn)行危險分級劃分，進(jìn)而確定上位機(jī)控制指令。基于nRF24L01無線傳輸功能可實現(xiàn)監(jiān)測模塊與上位機(jī)的無線通訊，進(jìn)行遠(yuǎn)程報警控制，從而提醒駕駛員注意周邊環(huán)境。本文在完成裝置的硬件設(shè)計與程序設(shè)計后，通過Proteus對裝置進(jìn)行了模擬仿真，成功驗證了設(shè)計可行性。該裝置具有適用車型廣、監(jiān)測范圍大、測量精度高等優(yōu)點，可有效對車輛視野盲區(qū)內(nèi)物體進(jìn)行檢測與報警。

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，下一頁）
