Research on a Multi-channel Alcohol Driving Detection System Based on FPGA

文章提出一种基于FPGA多通道酒驾检测系统,选用FPGA作为主要数据信息处理单元,最多可实现8通道酒精浓度实时检测。系统主要通过压力传感器、酒精检测传感器采集车载环境信息,采集的数据信息经过滤波、AD转换等步骤后发送至微处理器进行数据处理,处理后的数据分通道上传至数据终端,数据终端将分通道绘制酒精浓度变化曲线、给出控制响应并保存原始数据,为后期多源信息融合及大数据分析提供基础数据支撑。

Absrtact:In this paper,a multi-channel alcohol driving detection system based on FPGA is proposed.With the use of FPGA as the main data processing unit,up to 8 channels of alcohol concentration real-time detection can be realized.The system collects vehicle environment information mainly through pressure sensor and alcohol detection sensor.The collected data information is sent to microprocessor for data processing after filtering and AD conversion.The processed data is uploaded to data terminal through sub-channels.The data terminal draws alcohol concentration change curve through sub-channels and gives control.The system responds and saves the original data,providing basic data support for later multi-source information fusion and large data analysis.
