System functions of Beijing Guangfa Ye Wei Electric Co., Ltd.

1 and KD-BAS equipment measuring range: our products adopt three-phase and four-wire incoming mode, with a wire diameter of 90 square meters, a standard current of 250A, and a maximum output of 400a. The outgoing wires of electric meters are all live wires, and the user's zero wire is connected to the public zero wire bar. The outlet of electric meter can be divided into full single outlet, full three outlet and single three mixed outlet. Single-phase can be 60 years, three-phase can be 25-30kw, and over 60 years, it will be measured by the large current meter of industrial transformer.

2. The on-off control of the circuit is realized by an internal dedicated module;

3. Various optional management modes based on prepaid management;

A) Prepayment management, that is, electricity is purchased first and then used;

B) Pay after using electricity, which can preset the maximum power for users;

C), electricity statistics without interruption;

4. Maximum power consumption setting and control management;

5. The measurement accuracy is high, reaching 1.0 level;

6, according to the statistics of electricity consumption data of each room;

7. Fault diagnosis;

8. Support card payment;

9. Can realize network inquiry, telephone inquiry and printing;

10, SMS, e-mail and large-screen devices can be added to realize low battery notification;

1 1, data storage, backup, running log, password protection and hierarchical authorization;

12. When the load terminal is short-circuited, it can realize power-off protection, query the electricity information of each household, and realize all-on, all-off or partial-on, and the system automatically conducts power-on and power-off actions.

13. Electricity metering and billing: After the electricity fee is paid in advance through the computer electricity sales management system, the computer saves the data in the equipment, and the system adds and subtracts the pre-stored electricity of each household.

14. The electric meter has low battery alarm function: the alarm power can be set. When the user's remaining power is lower than the alarm value, the electricity meter will give an alarm to remind the user to buy electricity. Without shutting down the unit.

1), the display screen shows an alarm.

2), using the user dormitory telephone alarm.

3) The system will automatically print and post the report.

4) The buzzer on the data manager gives an alarm.

15. Pre-purchase of electricity and free power cut-off: When the remaining power of the user is zero, the system automatically cuts off the user's electricity consumption, and after the user buys electricity again, the system immediately resumes power supply to the user.

16. Forced power-off: The system can power-off users forcibly, switch all users uniformly, or switch any user individually.

17. If the power exceeds the limit, the power supply will be cut off automatically. If the number of power outages is within a certain range (can be set), it can automatically power off the alarm. If it exceeds the set value, it will not send electricity again and wait for the operator to handle it.

18. Refund processing: When the user withdraws the rent, the system should be able to refund the unused electricity bill to the residents.

19. It has the function of power consumption statistics report. Prepaid meters should be able to count the monthly and cumulative electricity consumption of each household like post-paid meters.

20. It has the function of electricity price and electricity quantity adjustment, that is, when the current electricity price changes, the user's remaining electricity quantity should be automatically adjusted according to the electricity price.

2 1. In addition to networking function, it also has the functions of "radio frequency card selling electricity, inquiring and restoring power supply". The card reader has a liquid crystal display screen, which can realize the functions of remaining power inquiry, parameter setting and power supply restoration.

22. Server data storage: In order to prevent the data loss of the client, it is required that the database can be stored in the database server, separate from the client, and have the query opening function to facilitate multi-level query.

23, system security and data security facilities

A. Statistical analysis of data: Monitoring interruption can not only provide users with electricity consumption data and historical records, such as electricity purchase and surplus electricity, but also realize statistical analysis of data of electricity consumption terminals and general meters, which is convenient for property management.

B. The system has data storage function: when the system is powered off, the storage time of historical records is not less than 12 months, and it has data backup function. After the power supply is restored, the system can automatically restore the power supply to the equipment.

C. Load control and monitoring: In order to protect the operation safety of the main point network and prevent the main power grid from being overloaded or fully loaded for a long time, the system can realize load control and monitoring for each user.

24. Users' electricity consumption status can be read online: Users' electricity consumption status can be read online by running management software. If there is a power outage, the system will automatically analyze the reasons for the power outage (forced shutdown, arrears shutdown, malignant load identification, over-power, timing, etc.). ), to facilitate the management of property staff.

25. Full-screen monitoring function: each user can be monitored through the computer, and the remaining power and malignant load of the user's electricity consumption information can be grasped at the first time.

26 data export function: with the increase of user's electricity consumption time, the user's electricity consumption data of management center computer will also increase. In order not to affect the running speed of the computer, the user's electricity consumption data can be exported to facilitate data storage.

27. Real-time power display function: Real-time display of accurate data such as power consumption and function coefficient of users by running management software greatly facilitates property management.
