    摘要:

    傳統無(wú)人駕駛車(chē)輛遠程檢測系統,由于信號傳輸距離的影響,信號波在傳輸過(guò)程在電路耦合率衰減下出現監測信號清晰度降低,信號整體監測效果無(wú)法滿(mǎn)足實(shí)際檢測系統應用要求的問(wèn)題。對此設計系統通過(guò)采用矢量傳感器對系統變量、模量與定量數據進(jìn)行矢量統一計算,提出基于矢量傳感器的無(wú)人駕駛車(chē)輛信號遠程監測系統。首先完成基于矢量傳感器的系統總體框架設計;然后根據設計框架建立無(wú)人駕駛車(chē)輛監控信號交互硬件單元,通過(guò)不同矢量傳感器構成監控信號數據矢量轉換計算平臺;最后通過(guò)對硬件平臺的矢量化軟件適配,完成硬件與軟件監控信號統一,提升信號傳輸強度,增強信號清晰度,從而滿(mǎn)足無(wú)人駕駛車(chē)輛信號遠程監測要求,完成提出系統的設計。通過(guò)對比實(shí)驗數據表明,提出設計的基于矢量傳感器的無(wú)人駕駛車(chē)輛信號遠程監測系統,能夠在50km~100km范圍內穩定監測車(chē)輛狀態(tài),車(chē)輛狀態(tài)數據監測實(shí)時(shí)性與連續性明顯優(yōu)于傳統檢測系統。

    Abstract:

    Due to the influence of signal transmission distance, the traditional remote detection system for driverless vehicles has the problem that the clarity of the monitoring signal is reduced under the attenuation of circuit coupling rate, and the overall monitoring effect of the signal can not meet the application requirements of the actual detection system. In this design system, vector sensors are used to calculate the system variables, modulus and quantitative data, and a remote signal monitoring system for driverless vehicles based on vector sensors is proposed. Firstly, the overall framework design of the system based on vector sensor is completed; secondly, according to the design framework, the interactive hardware unit of unmanned vehicle monitoring signal is established, and the vector conversion calculation platform of monitoring signal data is constituted by different vector sensors; finally, through the vector quantization software adaptation of the hardware platform, the unification of hardware and software monitoring signal is completed, the signal transmission strength is improved, and the efficiency is improved In order to meet the requirements of remote signal monitoring for driverless vehicles, the design of the proposed system is completed. By comparing the experimental data, it shows that the remote monitoring system of driverless vehicle signal based on vector sensor can stably monitor the vehicle status in the range of 50km ~ 100km, and the real-time and continuity of vehicle status data monitoring is obviously better than the traditional detection system.
