Multi-user smart meter manufacturers

Views: 信息来源:山东科大中天电子有限公司 发布时间:2014/9/9 Source of information: Shandong University of Science and Technology Zhongtian Electronics Co., Ltd. Release time: 2014/9/9
Main functions of multi-user smart meter:
Meter reading and sales functions: Through the management center using management software, the system can read the data of each meter and sell electricity.
Parameter setting function: Through the management center using management software, various parameters can be set according to the type of energy meter.
Control function: control the user's on / off state by computer.
Modification function: The system has the functions of modifying and setting the household information.
Expense settlement: The system calculates the user's expenses according to the meter reading or electricity sales records, and realizes that the public energy loss is evenly distributed or proportionally distributed to each household, and the fees payable by each household are automatically calculated in order to charge users.
Printing function: It can print the electricity sales records of each user, and can print the total list of all users and a single user list.
Data backup function: The system has data storage and backup functions. Software encryption function: The system implements authorized password operations. Special personnel operate with passwords. The system also has an operation log to record the operator's operation process in detail.
Account Opening and Account Closing Functions: The system can implement management functions such as account opening, account cancellation, room replacement, and fee refund for users.
Data filtering function: The system can filter and analyze the user's remaining power according to the set value to remind users to purchase electricity in a timely manner.
Query function:
1 Single-family inquiry: You can inquire the electricity sales records or remaining power of any household at any time.
2 Query on each floor: You can query the electricity sales records or remaining power of all residents of any floor at any time.
Main technical features: ** Up to 36 households can use centralized electricity detection, household metering and display. The meter box is small in size and easy to install. Accurate measurement, strong overload capacity, long service life, effectively prevent power theft and reduce power disputes. Wide range of 10 (50) A, high sensitivity, fully adapt to users with large changes in electrical load. With power metering function, it can directly display the user's electricity load, and can perform on-site meter calibration. The metering circuit and display circuit inside the electric energy meter adopt three-phase power supply. Even if the power supply line is out of phase, the energy meter can work normally, making the energy measurement more scientific. The power consumption of the whole machine is low, which is lower than that of a mechanical energy meter (7VA). With infrared short-range meter reading and computer remote network meter reading function, the meter reading method is more advanced. The case is stamped, sealed, and sealed with lead to meet international standards.
Main technical characteristics of centralized energy meters
1. Modular structure design:
Adopt the most reliable PIC microcontroller as the main control chip of the energy meter, and improve the quality of the energy meter from the root. Large-scale application-specific integrated circuits are used to collect electrical energy signals, which can measure the electrical energy in both positive and negative directions and accumulate in the same direction, effectively preventing the phenomenon of stealing and leakage. The interfaces between various functional units are standardized to facilitate user upgrades. Longitudinal and vertical structure design, galvanized shielding board is used to separate strong and weak electricity, which can avoid strong electric interference to weak electricity. The internal power supply has three-phase power supply, the power supply is out of phase, and the meter works as usual;
2. Three-core design:
Using three CPUs, communication interaction, measurement, and display are handled by different CPUs, each performing its role, ensuring that pulses are not lost during communication, making measurement more accurate and communication response faster.
3. Display design The display CPU is responsible for the dynamic scanning display to avoid electrostatic radiation display garbled characters, while providing the ability to send display data to the second display screen wirelessly or wired.
