Prepaid electricity sales management system

System Overview

With the rapid development of the economy, energy scarcity and environmental degradation have received close attention from the world. Energy is an important foundation for the development of the national economy. In order to respond to the country's needs and take the path of sustainable development, energy conservation and consumption reduction are the primary tasks. Among them, electricity consumption is relatively large among all energy sources, and the consent management of electricity is particularly important. Only accurate and reliable measurement of electrical energy can truly save energy.
The Yike Prepaid Electricity Sales Management System is a specialized, highly automated, easy-to-use, high-performance, and highly reliable electrical energy management system developed by our company to closely grasp the needs of power system users and follow the standards and specifications of the power system. It is suitable for low-voltage distribution systems. Through telemetry and remote control, loads can be reasonably allocated, optimized operation can be achieved, energy can be effectively saved, and there are records of peak and off peak electricity consumption, providing data basis for the rational management of electricity consumption.
This electricity sales management system can be widely used in commercial office buildings and enterprise office buildings, transportation hubs and commercial complexes, shopping malls and trading markets, school parks, dormitories, residential and public places, etc.

Function Introduction

Account opening management
Enter new users into the management system for easy information management and querying in the future.
■ Purchase/sale of electricity
You can input the purchase electricity degree, and the system will automatically calculate the amount based on the preset store. You can also input the amount to automatically calculate the electricity degree.
Electricity price management
The price of adjustable electricity bills is only authorized by the administrator account.
Report statistics
It can perform statistical analysis, export, printing, and other functions on the electricity consumption data of various users.
■ Reset the electricity meter to zero
Only the administrator account has permission to clear the data of electrical energy and quantity in the meter.
■ Power Authority
Allow users to use the maximum load power, beyond which the meter will automatically trip and cut off power.
For example, if the total household electricity load is set at 3000Q, the power will be cut off if it exceeds it.
■ Account cancellation operation
Used to cancel the profile and other information of electricity meter users, with only administrator account privileges.
■ Power outage/disconnection
By remotely opening/closing the circuit through the system, it facilitates the maintenance and repair of one's own circuit, and can also be used as a restriction on user electricity usage and other operations.
■ IC power purchase card
The electricity purchase card's electricity sales information is consistent with the system, and the two can be used interchangeably.
■ Historical query
Query and analyze the user's historical electricity usage.
■ SMS reminder
Also known as power alarm, when the remaining power on the meter is less than the set value, the system reminds users to purchase electricity in a timely manner through SMS on their mobile phones. Divided into first level alarm prompts and second level alarm prompts.
Malignant load permissions
Allow users to use the maximum malignant load value, and the meter will automatically shut down if it exceeds the maximum value.
For example, if the power is set to 2000W, the use of electric soldering irons exceeding this value will be restricted, or this restriction can be waived.

IC card electricity sales mode
Scheme Introduction:
IC card electricity sales do not require on-site wiring, directly connecting the meter's input terminal to the mains power and the output terminal to the user circuit, which is fast and convenient; One meter, one card, easy and fast operation.
The user purchases electricity from the electricity sales management department through an IC card, inserts the successfully purchased IC card into the electricity meter, and stores the purchased electricity in the meter. The "IC Electricity Sales Management System" stores the user's data.

Remote electricity sales mode

Scheme Introduction:
Remote electricity sales require on-site wiring. One communication line can connect to 247 electricity meters, and one line is connected to a port of a serial port server. The serial port server is connected to the switch through a network cable (with fewer users, the line can be directly connected to the terminal computer). The switch is ultimately connected to the terminal computer through a network cable, and the user's electricity purchase data is written to the energy meter through the RS485 bus.
Implement point-to-point layout, with clear and concise wiring methods, making it easy to investigate the causes of electricity problems in the later stage. The terminal computer only needs one network cable to perform all electricity sales operations such as opening, selling, and closing accounts for all electricity meters.

Hybrid electricity sales model

Scheme Introduction:
Hybrid electricity sales is a sales model that combines IC card electricity sales and remote electricity sales. In the early stage, it has the advantages of simple and fast IC card electricity sales, and no wiring required; The remote electricity sales operation in the later stage is convenient, and customers do not need to perform card insertion and removal steps, achieving intelligent energy management.
Suitable for temporary power purchase through IC card when RS485 network malfunctions and requires maintenance, or when the RS485 network is in the construction phase; After the 485 network is unobstructed, purchase electricity remotely and synchronize data; Or it can be used for recharging IC cards for electricity consumption during the early stage of construction at the installation site of the electricity meter, and for homeowners to settle in for intelligent remote electricity sales in the later stage.
