How to see the degree of single-phase prepaid energy meter

Shandong University of Science and Technology Zhongtian Electronics Co., Ltd. specializes in the production and production of pre-paid energy meters, DF multi-user smart meters, multi-user energy meters, electronic meters, apartment ** meters, high-current centralized meters, and multi-user smart meters. Sales.

The one-way prepaid energy meter display looks as follows:

1. The number on the meter is the degree, and the available power and used power are exchanged and displayed.

The IC card meter is composed of a base meter, a main control single chip, a digital display, a relay switch, an ESAM module and an IC card interface.

The work is mainly completed by two functional systems: the measurement system and the single-chip microcomputer processing system.

2. Measuring system: It is a single-phase electronic energy meter. The working principle is: voltage sampling is performed by the voltage divider, and current sampling is performed by the sampling resistor. The sampled voltage and current signals are converted into power signals by the multiplier. After V / T conversion, the meter is driven to work and the pulse signal is Enter the single-chip microcomputer system.

3. The user needs to pay for electricity in the power supply department. The purchased electricity is written into the user's electric card on the sales motor, and the electric card is passed to the meter. The electric card is encrypted multiple times to ensure the user can use it reliably. When the purchased power is used up, the relay in the meter will automatically cut off the power supply circuit.
