【摘要】：高速公路控制箱是高速公路监控系统的关键设备,它能够辅助监控设备完成高速公路监控任务,其工作状态的好坏直接关系到高速公路监控系统的正常运行。但是,到目前为止,对控制箱只有人为的定期巡检,不能实时掌握控制箱状态并且耗费人力资源。针对目前的不足,本论文设计了针对控制箱的监控系统,用于实时检测控制箱的电压、电流、温度以及湿度等参数,并通过以太网络通讯实时传送至监控中心,以预防事故发生。本设计主要包括以下四部分内容:1)设计了基于STM32F429的监控系统,包括电参量测量、温湿度测量等模块,可以实现对电压、电流、温度以及湿度等参数的测量;设计了基于以太网的通信系统,可以实现数据的远距离传输。采用了基于DSM-300的RFID识别系统,可以实现对维修人员在线情况进行实时监控。2)针对快速傅里叶变换的电参量测量方法的频谱泄漏、相位误差比较大的问题,采用了基于Hanning窗改进相位差校正法进行了改进,减小频谱泄漏,降低相位误差,提高测量精度。3)设计了远程监控系统软件,采用模块化的设计方法,包括电参量测量、温湿度测量、以太网通讯等模块,可以实现对电压、电流、温度、湿度等参数的采集以及数据的远距离传输。4)对电压、电流、温度、湿度等参数进行了测量实验和数据对比实验,测量结果表明,本系统可以实现对高速公路控制箱进行电压、电流、温度、湿度等参数的远程实时监控。
[Abstract]:The control box is the key equipment of highway monitoring system, it can facilitate the completion of the highway monitoring equipment monitoring, the working state is directly related to the normal operation of highway monitoring system. However, so far, only one of the control box for regular inspection, we can not grasp the real-time control box state and the cost of human resources for. The present shortage, this thesis designs the monitoring system for the control box, control box for voltage detection, real-time current, temperature and humidity parameters, and through Ethernet communications transmitted to the monitoring center, to prevent accidents. This design mainly includes the following four parts: 1) design of the monitoring system of STM32F429 based on the measurement of electrical parameters, including temperature and humidity measurement module, etc., can be achieved on the voltage, current, temperature and humidity measurement parameters; design The communication system based on Ethernet, can realize remote data transmission. The RFID recognition system based on DSM-300, can realize the real-time monitoring of the.2 online maintenance personnel) according to the spectrum of electric parameters measurement method of fast Fourier transform of the leakage, the phase error big problem, based on improved Hanning window phase difference correction method was improved, reducing spectrum leakage, reduce phase error, improve the measurement accuracy of.3) to design the remote monitoring system software, using modular design methods, including the measurement of electrical parameters, temperature and humidity measurement, Ethernet communication module, can realize the voltage, current, temperature, humidity and other parameters and data acquisition remote transmission of.4) on the voltage, current, temperature, humidity and other parameters were measured and compared the experimental data, the measurement results show that this system can realize the high speed. The road control box is used for remote real-time monitoring of voltage, current, temperature, humidity and other parameters.
