Distributed Remote Traffic Monitoring System To Achieve

This paper discusses the principle and development of Distributed Remote Measurement and Supervision System for Flux.The system solves the flux measuring problem of multi-points in distributed location by using a central computer and a lot of distributed computers. The central computer communicates with the distributed computers which use Programmable Logic Controller-PLC as CPU by modem module. The system is supervised and controlled by the central computer.The Distributed Remote Flux Measurement and Supervision System is made up of four main parts:1.Central ComputerThe software in central computer supervise and control the whole flux measuring system. The data of flux are collected, processed, recorded by the central computer. It also has the function of system parameter setting and high or low flux warning2.Programmable logic ControllerThe Micrologixl000 PLC make the flux sensors to convert flux and send the data to central computer. The central computer can communicate with any Micrologixl000 to acquire flux data.3.Modem ModuleThe modem module enable the system communication through long distance.4.ABB Sensitive FlowmeterThe ABB sensitive Flowmeter, provides the highest perfonnance in the presence of roping and distribution of flux. Therefore the greatest flexibility of options are available when choosing a location to site the meter. Each sensor features a completely smooth internal bore which enables the longest possible interval between inspections. An expected life in excess of ten years is typical. All three measurements, velocity, concentration and flux, are made within the sensor.
