的发展前景： Development prospects of multi-user energy meters :
With the continuous development of multi-user energy meter technology and the service awareness of related domestic industries, in the meters related to the daily life of residential users, the multi-user meter technology has been rapidly promoted and applied. It is widely used in the management of residential and production electricity charges.
Multi-user energy meter is a new type of meter that adds multi-user energy meter and load switch control function modules to the energy metering instrument to complete the electricity collection and settlement. Because the use of IC card electricity meters eliminates the manual meter reading process, the charging method is changed to sit-down, which greatly reduces the number of staff and has a significant work efficiency **, so it is generally recognized in the residential property management and power supply department's electricity collection. And application.
Multi-user energy meter is a large-scale power collection module composed of a power tax bureau collection instrument. It has advanced functions such as user power collection, remote data transmission, user power control, and multi-rate power metering. It is small in size and powerful in function. It is welcomed by users of centralized power supply places such as college student dormitories and intelligent communities.
In order to maximize the flexibility of the meter, there are some programmable parameters. Once some data is disturbed and damaged, not only the meter cannot work normally, but also economic losses to the user and economic disputes according to law, so the reliability of the data is guaranteed. , **, non-volatile.
The multi-user energy meter company analyzes for everyone. The power consumption of each user is converted into a pulse amount proportional to the power through a large-scale power metering integrated circuit. After the electrical coupling circuit, the switch input interface is cpu. Such as in memory.
The multi-user electricity meter tells you that in order to ensure the reliability of the meter, a photoelectric isolation circuit is designed in the data set circuit and the remote transmission circuit. In order to achieve non-volatile storage of parameters and data, the meter uses two types of memory. The two types of memory cooperate with each other and are equipped with software measures to realize non-volatile and highly reliable storage of data.
