IoT cloud electricity meter

Introduction:

The IoT cloud meter does not require wires or WIFI, and can be directly connected to a mobile phone. No matter where it is, it can be remotely read, charged, controlled, and closed. Managers and users can directly access energy consumption data, flexibly set the number of reports per hour, and process a series of energy events and data statistics, achieving true IoT meters. This product has a wide range of applications, such as residential apartments and buildings, which greatly reduces the burden on property management and operating costs. For shopping malls, industrial parks, and office buildings, not only is there unified overall management of the property, but it also enhances the service competitiveness of the property.

Comprehensive introduction to the advantages of IoT cloud electricity meter functions:

(2.1) No manual meter reading is required, which is conducive to modern management. The use of IoT cloud electricity meters avoids the inconvenience caused to customers by manual meter reading and door-to-door charging, and historical electricity purchase data can be saved for easy customer inquiry;

(2.2) Fully embodies the commodity attributes of electricity. Implementing the policy of buying electricity before using it, customers can purchase and use electricity according to their actual needs in a planned manner, without incurring late fees or unnecessary expenses due to overdue payments;

(2.3) Solved the problem of difficult charging. Can effectively solve the charging problems of scattered residential customers, temporary electricity customers, and customers who frequently owe fees;

(2.4) Long life: Adopting SMT technology and optimized circuit design, the whole machine does not need to adjust the circuit after leaving the factory;

(2.5) Low power consumption: Adopting a low-power design to reduce power grid line losses;

(2.6) Pre order electricity quantity; IC card transfers data and implements data retrieval, including: retrieval of total power consumption, remaining power consumption, accumulated purchased power in the meter, total purchased power times, and other information;

(2.7) Store table constants, initial values, user addresses, names, and other information;

(2.8) Overload alarm, power outage, remaining power alarm, reminding users to purchase electricity in a timely manner;

(2.9) Alarm function: When the remaining power is less than the alarm power, the meter will always display the remaining power to remind the user to purchase electricity;

(2.10) Data Protection: Data protection adopts all solid state integrated circuit technology, and data can be retained for more than 10 years after power failure;

(2.11) Battery level prompt: When the remaining battery level in the meter is equal to the alarm battery level, it will trip and cut off power once. The user needs to insert an IC card to restore power supply. At this time, the user should purchase electricity in a timely manner;

(2.12) Automatic power outage: When the remaining power in the energy meter is zero, the energy meter automatically trips, interrupting the power supply. At this time, the user should purchase electricity in a timely manner.

(2.13) Write back function: The energy card can write back the user's cumulative electricity consumption, remaining electricity, and zero crossing electricity to the power sales system for easy statistical management by the management department;

(2.14) User sampling function: The electricity sales software can provide data sampling of electricity consumption and provide priority sampling user sequences according to requirements;

(2.15) Electricity consumption query: Users can log in to their accounts to display the total purchased electricity, number of purchases, last purchased electricity, cumulative electricity consumption, and remaining electricity consumption, making consumption transparent and more user-friendly;

(2.16) Anti theft function: One meter and one card cannot be copied, with logical encryption. Effectively prevent technical electricity theft;

(2.17) Overvoltage protection function: When the actual electrical load exceeds the set value, the meter will automatically cut off power, insert the user card, and restore power supply.
