[0041] The system software has a modular structure and has rich functional modules such as system information management, basic information management, equipment monitoring management, account data management, statistical report management, inspection and repair management, and third-party interface management.

[0042] The system software adopts B / S architecture design, which is in line with the development trend of application software; this prepaid management system is a network version, which can support multiple management terminals to manage at the same time. The management terminal does not need to install the corresponding management software, but only needs to open the network address of the data server and enter the password to log in. It is very convenient for management personnel.

[0043] The communication server and client management programs support the Windows system; the database should use the MS SQL Server database system; the system sends instructions to the smart meter terminal, and the response time is ≤500 milliseconds.

[0047] The energy management platform unifies the electricity and water metering of the same user into one account (with sub-accounts at the same time), and manages it in a unified manner using a set of software. When the account balance is insufficient, power outages and payment reminders can be implemented, thus achieving the purpose of prepayment and realizing unified water and electricity management.

[0048] The energy management system can be used independently for electricity systems, water systems, water-electricity joint management systems, etc. through simple configuration during initialization.

At the same time, through in-depth data mining and analysis, it can also help users achieve the goals of energy conservation and emission reduction, improve energy efficiency, and promote sustainable development and the realization of a green lifestyle.

[0058] The smart water and electricity management system is a comprehensive management system that integrates advanced Internet of Things technology, cloud computing, big data analysis and other technologies. The system is designed to transmit the data collected by smart water and electricity meters to the smart data gateway through wired and wireless methods, thereby realizing the real-time collection, transmission, processing, analysis and display of water and electricity data. Users can understand and manage water and electricity usage anytime and anywhere through web pages, WeChat applets and other access methods, providing strong support for energy conservation and emission reduction and improving energy efficiency.

[0059] In the embodiment, the system has two charging modes: prepaid and postpaid, and the two modes can be easily switched.

[0060] In prepaid mode, users must recharge before using electricity. When the balance is ≤0, the meter can automatically cut off the power at the set time (immediately, at a specified time every day, or at a specified time every week) to avoid affecting the normal business activities of merchants. After the user recharges to correct the balance, the meter will automatically open the gate and supply power immediately. In postpaid mode, the meter will not be cut off due to arrears.

[0061] The system automatically reads the meter at the set time (the automatic meter reading time interval can be set individually) and stores the meter reading results for future reference.

[0062] System administrators can customize the content of automatic meter reading: combine the readable data parameters into the required reading modules, such as combining the malicious load tripping, overload tripping, overvoltage tripping, etc. into the "abnormal tripping" data block. When reading the meter, only the abnormal tripping needs to be read, and all the parameters included will be read at once. The system meter reading success rate must reach 100%, and the meter reading accuracy: the absolute error is less than 0.1KWh.

[0063] The present invention can monitor the power consumption of all meters in real time, as well as the total cumulative power consumption of each meter, the power consumption of the current month and the previous two months, and the current current, voltage, power, power factor and other parameters. It can remotely monitor the operating status of each device in real time. It can manually select a single or multiple meters to display the selected meter information and perform operations such as tripping or closing the meter. If the system is in arrears power-off mode, the system will send a power-off command to all users in arrears at a specified time to remotely power off. The power-off time can be set by the administrator to control the timer switch: the timer time is selected by room and identity, and a room only selects a set timer schedule to perform corresponding timer time control.

[0064] In the data acquisition layer, each meter or meter module has its own CPU, which can independently realize all control functions. The meter or module has its own load detection function, and the threshold can be set through the data center, which is determined by the actual use of the user, to realize the automatic shutdown function of overload and malicious load, and ensure the safety of electricity use. The time switch function can be set in weeks, and 4 time switch time periods can be set every day; the switch time period of holidays can also be set as needed. It has a time-limited power function, which can limit different overload power in different time periods. It has a variety of rates and time-sharing billing functions. The large-screen LCD displays account data and function parameters. It has a 485 remote communication interface and an infrared local data interface, and a built-in LORA wireless communication module to realize wireless remote meter reading and control functions. They all have voltage-resistant and anti-interference isolation designs to ensure stable and reliable communication.

[0065] Smart water meters all use photoelectric direct reading absolute encoding, automatically memorize the code wheel position, and do not need initialization; directly read the window value, no cumulative pulse conversion, no cumulative error, and realize direct reading of the meter wheel data, ensuring the complete unification of meter measurement data and background data. Using M-BUS bus technology, only two wires are needed for communication and power supply, and there is no need to distinguish between positive and negative polarity, no external power supply is required, and installation is convenient. The system adopts a three-level structure with excellent system scalability, which is convenient for management departments to add new meters; the meter has a unique ID number, and a complete production, commissioning, use and maintenance record is established. The fully sealed design has good waterproof performance and can work normally in water. It is not affected by external strong magnetic attacks and has extremely high anti-interference performance; it effectively solves the problems of water meter reversal and water hammer.

[0066] The data gateway is a key device in the energy consumption monitoring system. The downstream is connected to the smart electricity meter, smart water meter, flow meter, gas meter, temperature sensor, pressure sensor and other field measurement and monitoring equipment through RS-485 and MODBUS mainstream communication protocols to perform parameter setting, command issuance, data collection, data freezing, status monitoring, etc. The upstream supports multiple communication methods: RS-485, TCP / IP, GPRS, etc. to connect to the management server to receive configuration commands and upload collected data.
