Research On Remote Monitoring System Of Intelligent Urban Water Affairs Based On Cloud Platform

With the rapid development of the Internet of Things technology at home and abroad,the figure of the Internet of Things technology can be found in human life.People apply the Internet of Things technology to the urban water monitoring system,which can not only improve the monitoring and governance capabilities of the urban water system,but also optimize Water management model.At present,the smart city water remote monitoring system adopts the form of an independent system,which is composed of three parts: the upper monitoring part,the communication network,the field control and the acquisition part.First,The upper monitoring part is composed of workstation computer,LED display large screen,network version monitoring software and industrial switch.The cost of composing the upper system is high and the system is complicated to build.Second,The communication network uses GPRS to communicate,but it is not particularly suitable to use it,because the number of terminals that GPRS can access is relatively small and there are relatively large nu mber of remote control terminals for water affairs in large cities.At last,The on-site control and acquisition part is composed of PLC controller and sensing equipment.The PLC controller has a relatively bulky shape,high cost and is not conducive to installation.In this design,MSP430 is used as the intelligent control terminal to realize the functions of data acquisition,processing,control and so on.Compared with PLC controller,MSP430 has the advantages of energy saving,fast processing speed and low price.The One NET cloud platform serves as a server for data analysis,storage,and forwarding.Compared with the current upper monitoring system,the One NET cloud platform uses computer clusters to process received data,and can analyze and store large amounts of received data at high speed.One NET cloud platform can be applied directly without independent development.After successfully logging into the remote monitoring client-side,the staff can issue control commands and real-time monitoring data through the remote monitoring interface.As the communication module of this system,NB-IOT can access 50-100 times the number of terminal devices than the general communication system.Therefore,it is more suitable for application to the network communication of water monitoring system in large cities.The work completed in this design includes monitoring the data of the water supply pipeline pressure,water temperature and water quality PH value.One NET analyzes the collected data,and when the data value reaches the trigger condition,it will trigger the mail alarm function;One NET can analyze the discharge and water supply pressure of water supply plants in various regions and time periods,and use improved particle swarm algorithm to optimize water dispatching,and achieve the lowest total cost and energy consumption of multiple water supply plants.Then the One NET cloud platform is used to issue control commands,intelligent terminal control frequency converter,change the motor speed,and adjust the opening of the multi-stage centrifugal pump;When the pipeline bursts,the location information can be used to quickly locate the leaking pipeline location information.
