Multi-user meter manufacturers remind you of several factors that you must consider when choosing a multi-user meter:
1.Flexible installation methods: layered installation or cabinet installation, layered installation ** can manage 36 rooms (single output) or 18 rooms (dual output); cabinet installation ** can manage 240 Rooms.
2, with real-time power display function, real-time display of the user's power load.
3. It has the function of timing power off and on: It can set the time period (maximum 8) divided in one day and the on-off status of each user's relay in different time periods through instructions to realize the user's timing on-off control.
4, with the user's dual-loop power supply function: the 2 outlets of the meter are provided to a user for use, except for the total calculation of the 2-wire power consumption, the function of each power supply line of the user is exactly the same as that of the selected meter type, The parameters can be set separately to achieve independent control.
Multi-user meter manufacturers describe the scientific description of multi-user smart meter data storage technology:
The power consumption of each user is converted into a pulse amount proportional to the power through a large-scale energy measurement integrated circuit (such as BL0933, ADE7755, etc.). After the photoelectric coupling circuit, the switch input interface is taken into the memory by the CPU According to the collected pulse amount, the CPU accumulates the power consumption of each user, stores it in a non-volatile memory, and the display circuit displays the power consumption of each household in turn. Remote transmission of measurement data through remote communication interface circuits (such as RS485, CAN bus).
For the flexibility of meter usage, there are some programmable parameters, such as meter number, number of metering households, communication rate, meter pulse constant, time value of multiple rate period, power supply status of each household, etc., as well as its metered data, That is, the power consumption of each user. Once these data are disturbed and damaged, not only the meter cannot work normally, but also economic losses to the user and economic disputes. Therefore, the data must be reliable, volatile, and non-volatile.
Multi-user smart meter is a kind of power data collection meter with MCU as the core and a large-scale power collection module. Small and powerful, it is welcomed by users in centralized power supply places such as college student dormitories and intelligent communities.
If you want to extend the service life of multi-user meters, you need to know how to reduce the use of multi-user meters and reduce the occurrence of failures. You can replace the internal components as little as possible, keep the original combination, and use the performance more stable.
In order to reduce the occurrence of failures, we must learn to use electricity correctly. Do not wait for the meter to remind you to store electricity before buying electricity, and ensure that it regularly stores electricity **. When using home appliances, you should also pay attention to the power. Do not overload the power. Sometimes the power is too large. In order to protect the circuit, the meter will automatically trip. The frequency of automatic trips is too much, which will cause certain damage to the internal circuit. Multi-user electricity meters are usually installed in the corridor. Few people pay attention here to prevent dust from entering the electricity meter.
The multi-user electricity meter manufacturers have said so much. I believe you have learned a lot. If you want to know more, please call us. We will update the ??im体育娱乐?? regularly and follow us quickly!
