Smart Meter Management Platform
The smart instrument cloud platform is a comprehensive management platform integrating system management, equipment management, production management,marketing charges, data copying, energy consumption analysis, intelligent early warning and other functions. Based on water meters, flow meters, heat meters,electricity meters, intelligent control valves, pressure sensors, water quality analyzers and other equipment, each meter is intelligently connected through the built-in communication module and datacollector to realize two-way communication from the terminal to the cloud , collect the data into the cloud database, and build a cloud intelligent management system, so as to realize functions such as remote automatic copying, intelligent control, independent settlement, online payment, energy consumption analysis, and energy saving management.
The platform adopts SaaS architecture, supports all mainstream browsers, multi-users can manage and operate collaboratively, which greatly improves work efficiency. All data are stored in the cloud to avoid loss.
Data reading and marketing charging are integrated, so there is no need to use two systems. Support tiered electricity price, tiered water price billing, and various marketing strategies such as discounts and exemptions.
Support WeChat or Alipay online payment, query usage, balance, payment and other information. it can be connected to third-party platforms, such as one-card system, UnionPay, etc.
Unified management of accounts, roles, permissions, etc., monitoring of various abnormalities and centralized management of various notification messages on the platform. At the same time, log management is carried out for all tasks, actions, communications, etc., which is convenient for managers to supervise.
Provide up to 24 months of reading records and storage of usage information. Data that exceeds the time limit can be retained or discarded according to customer needs; sensitive data is encrypted and stored using various means such as AES to ensure data security.
Integrated into WeChat, Alipay and other platforms, it is convenient for users to contact customer service, check bills, pay fees, etc.
A typical smart water application solution is shown in the figur on the right. Through various transmission methods such as Cat.1, NB-IoT, LoRa, and cable,the solution overcomes the influence of traditional water meters on installation location, complex community environment, and weak signal coverage, and effectively solves the problem of reliable data transmission between smart water meters and the system. Online monitoring, automatic management, unmanned meter reading, and remote control of water meters have greatly improved the level of intelligent management of meters and effectively reduced the operating and management costs of water supply service units.
NB-IoT Internet of Things communication technology has the characteristics of low power consumption, wide coverage, large connection, high security and so on.The NB-IoT water meter directly communicates with the cloud server through the telecom base station to realize meter reading and data exchange. No intermediate equipment such as a collector is required, the system structure is simple, and maintenance is convenient.
When real-time transmission is required or the NB-IoT network is not covered, the LoRa transmission method can be used to transmit the data to the data collector, and then the data collector will summarize it to the cloud platform.
The system is also compatible with traditional wired water meters such as M-BUS and RS485. The meters are intelligently connected through the data collector, and the data is converted by the collector and transmitted to the server through the 4G/5G public network to realize the unification of meterswith different transmission methods compatible.
A typical heating energy-saving application scheme is shown in the figure below. By configuring heat meters, intelligent control valves, temperature controllers,collectors and other instruments and equipment, this solution overcomes the traditional heating scheme that is based on metering alone under the conditions of "household cycle,room temperature control, metering and charging". There are many disadvantages such as charging, charging by time, charging by area, etc., adopting a variety of heating energy-saving methods such as integrated measurement and temperature control, on-off time area method, and temperature area method to effectively solve the problems of metering, charging, and energy saving in smart heating. balance problem. It not only realizes the automation of heat metering, automatic control of user heat consumption,intelligent system regulation, and scientific platform supervision, but also realizes the overall energy saving and consumption reduction of the heating system,effectively reducing the operation and management costs of heating units.
According to the International Water Association (IWA) pipeline network leakage control strategy and DMA management method, the pipeline network monitoring and DMA partition metering system were developed. The system senses the operating status of the water supply system in real time through online monitoring equipment such as flow meters, pressure sensors, and water quality analyzers, and visualizes the operating status and key data of water supply facilities to form an "urban water Internet of Things". The pipe network monitoring and DMA partition metering system includes multiple subsystems such as GIS information system, file management system and data analysis system. According to the service area of the pipe network and the length of the pipe network, the water supply area is divided into multiple measurable partitions (DMA). Carry out regionalized and grid-based management of the water supply pipeline network of the entire city, analyze and process massive water affairs information in a timely manner, accurately measure regional water leakage and production-sales difference, and scientifically analyze pipeline network and all levels of zoning leakage and production-sales difference The reasons for the effective management of urban water supply, water consumption, water consumption, leakage and so on.
Urban water-saving management system is an information management system platform developed to create a water-saving city and further do a good job in water-saving management. The main content of the water-saving information management system is the informationization of daily business management, fully integrates the planned water use and real-time monitoring data of water use, and provides information services and technical support for the modern management of water resources utilization. provide efficient management means for managers, improve work efficiency, and better serve the public.
The "Urban Water Saving Information Management system" is established by using water resources data collection and transmission technology, computer network technology, database construction and query technology, geographic information system, multimedia technology and so on. to provide an efficient management platform for urban water resources management.
The system adopts browser / server architecture, and the client does not need to install software.
You only need one browser to use it, which supports all the major browsers at present.
The software upgrade and maintenance is convenient, and the client basically achieves zero maintenance.
The design of the new Bhand S architecture solves the problem of slow speed caused by the large amount of data in the Internet network, and it is more convenient to expand and expand new functional options.
