针对现有路灯控制器在节能和故障检测方面的不足,本文提出一种智能路灯控制器设计.该控制器综合利用多传感器信息实现夜深无人时段的人员和车辆检测,在无人车经过时关闭或降低路灯亮度,减少不必要的电力消耗.并实现路灯工作状况的自检,通过电力载波通信实现控制器与路灯管控中心的数据通信,实现远程故障监测.
Aim at the deficiency of the traditional fuzzy controller,the design of improved fuzzy controller with correction factor is designed in this paper.The controller adds self-turning correction factor and Intelligent integral module.Simulation result shows that the performance of controller is good,this method is applied to the liquid level control system,and had achieved good effect.
为了解决现有路灯控制系统在节能和功能性方面的不足,本文提出一种多功能智能路灯控制系统方案设计。其中,控制器利用红外探测、亮度检测和车流检测等多传感器技术,检测到经过的人车时才开启路灯,从而减少电力消耗。利用电力线载波通信和无线通信技术实现路灯控制器与管理中心的网络互连,实现路灯工作状态的自动检测,从而减少人工巡检的工作量。并在此基础上,实现视频监控和车流量统计,扩展其应用范围。随着城市照明控制系统和控制需求多样化的发展,这种多功能的智能路灯控制系统将有广阔的应用前景。
It is talking about the research and development of automatic fire control system's design and application which is based on Matlab/Simulink.It supplies a new method and theory and builds a bridge between the theoretical simulation studies and real-time control.The method uses fuzzy PID control model of Matlab/Simulink to establish automatic fire system,it can connect material object through the I/O interface of Q8 card.Finally,the curve result can be given by the HILS experiment.The results show that it not only reduce the cost and improve the speed of RD but also bring so intuitive result compared to the old method.
The characteristics of OPC technology and the main ideas operating industrial control network are described. Comparingwith the C/S mode,the B/S superiority of design pattern is explained. The steps and methods of the realization of OPC Client usingthe way of managed code calling unmanaged code are described in detail. A production scheduling system is programmed with C#which is used in the production of a large company. Finally,security and flexibility of the system are analyzed and several of optimization methods are given. Through the successful operation of the system,the company's actual production rate is improved and anefficient and orderly operation is protected.
