This system designs an intelligent electricity metering and management system for commercial users such as commercial squares, property communities, farmers' markets, and campuses. It aims to achieve intelligent management of merchant electricity, so as to ensure the independence and safety of merchant electricity.This system combines prepaid functions, fee control functions, meter reading functions, etc. to realize prepaid electricity bill management, automatic meter reading energy consumption statistics, and remote fee control management, effectively eliminates malicious arrears of electricity bills, electricity theft and other bad behaviors, greatly reducing labor management costs.
The system includes all functions of account opening, power sales, remote control, meter reading and reporting;The main features are as follows:
◆Permission control: Can be used for administrators and users；
◆Quick configuration, ready-to-install: configure the meter and collector to the system to use, and add the radio meter directly to use;
◆Support network: GPRS、2G、4G、NB-LOT、 Ethernet；
◆Remote centralized meter reading: no manual meter reading, the real-time meter status can be accurate to within 3 minutes;
◆Unattended power sales and inquiry: Wechat and Alipay unattended, self-service payment and sales, users can check their own recharge records and electricity usage records, etc.；
◆Supports separate pricing, multiple rates, and step electricity prices: the electricity price, rate and step electricity prices can be set separately for each electricity table;
◆Remote power sales: centralized financial management, real-time amount is issued, and the number of recharges is compared to prevent cheating;
◆Data security: Network data transmission uses encryption algorithms to prevent data cheating and stealing power;
◆Mobile SMS reminder: When the amount is insufficient or the amount is owed, early warning can be provided and merchants can be notified in time by text messages;
◆Remote control: It can perform a series of remote control operations such as remote shutdown or power maintenance on any electricity meter for easy management;
◆Energy consumption query: Both users and administrators can check the daily purchase records and total power status of the prepaid table or control table.
◆Open data interface:Third-party platforms can connect to the system through data interface.( API Interface, hardware protocol docking can also be provided)
1.The system management software stores and processes the data, and the system management software performs remote centralized meter reading, power sales, and shuts down operations to form what the property management party needs. Documents in the form of text and other documents can realize the intelligent management of electricity used by merchants in the entire urban square.This solution has built-in IoT modules, no need to arrange485The communication line, the meter is the collector, and it can be used when powered on. The meter transmits data to the backend management through the built-in IoT card, which is easy to install and is suitable for the distribution of the meter relatively scattered.
2.The collector passes RS-485 The bus collects the number of all terminal electrical energy metering instrumentsaccording to. GPRS（4G） The collector transmits the data to the central management computer through a dedicated network composed of optical fibers.The system management software stores and processes the data. The system management software performs remote centralized meter reading, power sales, and shuts down operations to form documents such as texts required by the property management party, so as to realize the intelligent management of electricity consumption of merchants in the entire city square.Easy to install,Suitable for centralized installation.
