基于微机电系统加速度传感器的交通安全设施状态监测关键技术研究

Research on Key Technologies for Condition Monitoring of Traffic Safety Facilities Based on Accelerometers of Microelectromechanical Systems

在我国社会稳步发展的进程中,逐步构建了相对完善的道路交通网络。然而,当今城市道路车辆数量越来越多,道路交通安全事故频发,其中,有很大比例都是因为交通安全设施出现异常,因此对交通安全设施进行实时监测,对于营造安全的交通环境有重大意义。为此,本文研究了基于微机电系统(MEMS)加速度传感器的数据采集单元,用微处理器通过内部集成电路总线采集加速度传感器的数据。

In the process of steady development of China's society,a relatively complete road traffic network has been gradually constructed.However,the number of urban road vehicles is increasing,and road traffic safety accidents occur frequently,among which a large proportion are due to the abnormality of traffic safety facilities,so real-time monitoring of traffic safety facilities is of great significance for creating a safe traffic environment.To this end,a data acquisition unit based on an accelerometer based on a microelectromechanical system(MEMS)accelerometer is studied,and the data of the accelerometer is collected by a microprocessor through an internal integrated circuit bus.
