The smart meter is the smart terminal of the smart grid. It is no longer an electric energy meter in the traditional sense. In addition to the basic power metering function of the traditional electric energy meter, the smart meter also has two-way in order to adapt to the use of smart grid and new energy. Intelligent functions such as multiple rate metering functions, user-side control functions, multiple data transmission modes, two-way data communication functions, and anti-theft functions. Smart meters represent the future development direction of smart terminals for end users of energy-saving smart grids .
1. No manual meter reading is required, which is conducive to modern management. The use of IC card electricity meters avoids the many inconveniences to customers caused by manual meter reading and door-to-door charging, and historical electricity purchase data can be saved, which is convenient for customers to query.
2. It fully reflects the commodity attributes of electricity. With the implementation of buying electricity before using electricity, customers can purchase electricity and use electricity in a planned way according to their actual needs, and will not incur late fees due to arrears and increase unnecessary expenses.
3. The problem of difficulty in charging is solved. It can well solve the charging problems of scattered residents, temporary electricity customers, and customers who often owe fees.
4. The IC card meter has a variety of anti-theft functions, small starting current, no creeping, wide load, low power consumption, straight error curve, good stability during long-term operation, beautiful appearance, small size, light weight, and installation Convenience. High accuracy: Fully electronic design, built-in imported special chip, accuracy is not affected by high-order harmonics of frequency, temperature, and voltage.
5. Long life: Adopt SMT technology, optimized circuit design, no need to adjust the circuit after the whole machine leaves the factory.
6. Low power consumption: low power consumption design is adopted to reduce power grid line loss.
7. Pre-purchase power; IC card transmits data to realize data readback, including: read back total power, remaining power, accumulated power purchase in the meter, total power purchase times and other information.
8. Store table constants, initial values, user addresses, names and other information.
9. Overload alarm and power failure, remaining battery alarm, remind users to purchase electricity in time.
10. Technical parameters: Long-life base meter is adopted to extend the service life.
1. Alarm function: When the remaining power is less than the alarm power, the meter often displays the remaining power to remind users to purchase electricity
2. Data protection: Data protection adopts all solid-state integrated circuit technology, and data can be kept for more than 10 years after power failure
3. Power reminder: When the remaining power in the meter is equal to the alarm power, the power will be tripped and interrupted once, and the user needs to insert the IC card to restore the power supply. The user should purchase electricity in time.
4. Automatic power off: When the remaining power in the electric energy meter is zero, the electric energy meter will automatically trip and interrupt the power supply. The user should purchase electricity in time at this time.
5. Write-back function: The energy card can write back the user's accumulated power consumption, remaining power, and zero-crossing power to the power sales system to facilitate the statistical management of the management department.
6. User sampling inspection function: the power sales software can provide data sampling electricity consumption and provide priority sampling user sequence according to requirements
7. Electricity query: insert the IC card to display the total electricity purchase, the number of electricity purchases, the last electricity purchase, the cumulative electricity consumption, and the remaining electricity in turn
8. Anti-theft function: One meter and one card cannot be copied, logic encryption. Effectively prevent technical theft of electricity.
9. Overvoltage protection function: When the actual power load exceeds the set value, the meter will automatically cut off the power, insert the user card, and restore the power supply.
10. Low power consumption: adopt the latest design and SMT advanced production technology.
