With the rapid development of the economy, energy scarcity and environmental degradation have attracted close attention worldwide. Energy is an important foundation for the development of the national economy, in order to respond to the country's
The family calls for a path of sustainable development, with energy conservation and consumption reduction being the primary task. Among them, electricity consumption is relatively large among all energy sources, and unified management of electricity is particularly important. Only by accurately and reliably measuring electrical energy can we truly
Save electricity in a sense.
Our company has closely grasped the needs of power system users and followed the standards and specifications of the power system to develop a prepaid electricity sales management system for our company
A power management system suitable for low-voltage distribution systems with strong professionalism, high degree of automation, ease of use, high performance, and high reliability. Through telemetry and remote control
By reasonably allocating loads, achieving optimized operation, effectively saving electricity, and having records of peak and low electricity consumption, data basis is provided for reasonable management of electricity consumption.
The electricity sales management system can be widely used in commercial office buildings and enterprise office buildings, transportation hubs and commercial comprehensive buildings, shopping malls and trading markets, school parks, and accommodation
Housing, residential and public places, etc.
It can achieve data collection, tracking, and clear display of electricity consumption information for each unit. The system has a simple structure, clear, fast, and accurate display of electricity data, making it easy to calculate and manage the electricity bills of each electricity user.

Product Features
Account opening management
Entering new users into the management system facilitates subsequent information management and queries
Electricity purchase/sales
You can input the number of kWh purchased, and the system will automatically calculate the amount based on the preset electricity price. You can also input the amount to automatically calculate the kWh.
Electricity price management
The price of the electricity bill can be adjusted, and only the administrator account has permission.
Report statistics
It can perform statistics, analysis, export, and printing on the electricity consumption data of various users.
Clearing the electricity meter
Used to clear data on the electricity level in the electricity meter, only the administrator account has permission.
Power permissions
Allow users to use the maximum load power, and the meter will automatically switch off and cut off power if it exceeds this value.
For example, if the total load of household electricity is set to 3000W, if it exceeds, the power will be cut off.
Account cancellation operation
Used to log off the profile and other information of electricity meter users, with only administrator account permissions.
Power outage/opening
By remotely pulling/closing the system, it is convenient for self circuit maintenance and can also be used to restrict user electricity usage and other operations.
IC power purchase card
The electricity purchase card and sales information are consistent with the system, and the two can be mixed for use.
Historical Query
Query and analyze the user's historical electricity consumption.
SMS reminder
Also known as power alarm, when the remaining power of the meter is less than the set value, the system reminds users to purchase electricity in a timely manner through mobile phone SMS.
It is divided into first level alarm prompt and second level alarm prompt.
Malignant load permissions
Allow users to use the maximum malignant load value, and the meter will automatically power off if the maximum value is exceeded.
For example, if 2000W is set, the electric soldering iron that exceeds this value is limited or not set.
IC card sales mode
Scheme Introduction
IC card electricity sales do not require on-site wiring, and directly connect the incoming end of the meter to the mains, while the outgoing end is connected to the user's circuit, which is fast and convenient; One meter, one card, easy and fast operation.
Users purchase electricity from the electricity sales management department through an IC card, insert the successfully purchased IC card into the electricity meter, and store the purchased electricity in the electricity meter. At the same time, the "IC electricity sales management system" stores user data.
Recommended solution:
Remote power selling mode
Scheme Introduction
Remote electricity sales require on-site wiring. One communication line can connect to 32 electricity meters, and one line is connected to a port on a serial server through a network cable
Connect to the switch (with fewer users, the line can be directly connected to the terminal computer), and the switch will ultimately connect to the terminal computer through a network cable, and write the user's electricity purchase data into the electricity meter through the RS485 bus.
Realize the layout of point, line, and point, with clear and clear wiring methods, making it convenient for later investigation of power consumption problems. The terminal computer only needs one network cable to perform all power sales operations such as opening, selling, and canceling accounts for all electricity meters.
Recommended solution:
Hybrid electricity sales mode
Scheme Introduction
Hybrid electricity sales is a combination of IC card electricity sales and remote electricity sales, which has the advantages of simple and fast IC card electricity sales in the early stage, without the need for wiring; Remote power sales operation in the later stage
Convenient operation, customers do not need to perform card insertion and removal steps, achieving intelligent power management.
Applicable when the RS485 network malfunctions and requires maintenance, or when the RS485 network is in the construction phase, temporary electricity can be purchased through an IC card; After the 485 network is unblocked, use remote power purchase to synchronize data; Alternatively, it can be used for recharging electricity using IC cards during the initial construction phase of the electricity meter installation site, and for intelligent remote electricity sales by homeowners in the later stages.
