The Design And Implementation Of Wind-solar Hybrid Power Supply Remote Monitoring System For Water Networks Base On Cloud Backstage

Urban water supply is an important industry of national economy and people's livelihood.It is very important to obtain the status of the pipe network in a timely manner.With the expansion of cities in our country,urban water supply network coverage is wider than before,and the distribution also becomes more complex,which increases the difficulty of obtaining the situation of pipe network segment.Water supply network has been aging seriously in old cities of urban areas,Leakage is caused by the aging of the pipe.Existing technology lag,the simple equipment of power supply,the delay of data return and the failure to share data all lead to the phenomenon that monitoring system runs instability and unable to judge the leakage timely.These above give rise to lots of problems,including a huge waste of water resources,failure in analyzing the state of pipe through background data and to share the data industry inside.It is hard to cope with the new changes and development of urban water network.To solve above problems,the design and realization of wind-solar hybrid power supply remote monitoring system for water network base on cloud backstage is put forward in the thesis,which first proposes to apply the Wind-Solar Hybrid Power supply system to urban water network monitoring system.The system uses Wind-Solar hybrid power supply to replace the original disposable batteries,makes the environment clean and pollution-free,save on manual maintenance costs and ensures efficient use of resources.The real-time transmission of data is realized through the combination of the main control chip,the transmission module and the corresponding sensor.The water network monitoring system is set up to the cloud server for the first time.Cloud backstage can help to carry out background analysis and share data with the industry.The main contents of this thesis are as follows:(1)Wind-Solar Hybrid Power supply system consisted of solar panel,wind turbines and controllers.It is applied to calculate power,daily power generation and daily power consumption of load,which demonstrates the stability of system power supply.(2)Choose low-cost chips because of the need for large-scale applications,which designed a monitoring system consisting of STM32F103 master chip and SIM800 Acommunication module.It includes the main control chip selection,sensor selection,data collection,GPRS module design,power supply circuit design.(3)Ali cloud server was set up and the project environment required was completed.The upper computer software is designed by java language,receives the data sent by the hardware and stored in the MySQL database..(4)In order to achieve real-time sharing of background data,the B/S architecture was determined.MySQL database needed for the project and the web client has been designed.Finally,the software and hardware of upper computer are used to test the physical model and verify the function of the system.On the basis of the above research work,the design and implementation of Wind-Solar Hybrid power supply water network remote monitoring system bases on cloud backstage is finally completed.It improves the system efficiency and stability,and realizes the remote monitoring of urban pipe network data and data cloud backstage sharing function.
