How do multi-user smart meters look at the degree and calculate the electricity bill? Many people are still ignorant. The meter shows that there is so much content to look at. Which is the monthly meter usage rate or the period meter usage rate? 为我们举例解说智能电表怎么看度数及核算电费。 The following is Shandong University of Science and Technology Zhongtian Electronics Co., Ltd. as an example to explain how smart meters look at the degree and calculate electricity bills.
智能电表具有超负荷断电报警，远程控制停（送）电，抄读电表电量，分时计量电量等功能。 First of all, multi-user smart meters have functions such as overload overload alarm, remote control of power outage (sending), reading of meter power, and time-of-day metering of power. The multi-rate rate function is to measure the electricity in time, and divide the 24 hours a day into several periods (peak, peak, flat, valley).
Peak hours: peak electricity consumption, expensive electricity prices (higher than the basic electricity price),
Peak period: peak electricity consumption, followed by electricity price (higher than basic electricity price),
Flat time: normal electricity consumption, fundamental electricity price,
Valley period: less electricity, lower than the basic electricity price.
个时段电价不同，这个电价是由当地电力部门制定并经过相关部门同意的，用户能够经过电表看到不同时段的电量和总电量，但看不到电费。 The electricity price is different in each time period. This electricity price is set by the local power department and agreed by the relevant departments. Users can see the power and total power in different time periods through the meter, but they cannot see the electricity bill. Electricity charges are calculated by multiplying the power of each period by the relative price and adding them up. After 485 (or carrier wave) according to the DL645 protocol, it can also read the setting of the timetable of this table, and can read the last month, last month, this month's time-sharing power and total power, but can not read the electricity bill. In addition, since the 485 port of the energy meter is inaccessible to the user in the terminal cover, the user cannot read the energy meter information through 485, and a special reading device is also required after passing the carrier.
Multi-user combined watt-hour meters can be widely used in residential buildings, collective apartments, and other places of power consumption. They have small size, convenient meter reading, and anti-theft functions. They are ideal substitutes for old-fashioned mechanical watt-hour meters.
