Collecting power consumption data is the precondition for monitoring the energy consumption of the computer room. Conversely, the edge device (gateway) is connected to the intelligent inductance measurement terminal through a 485 bus. This part of communication is based on the Modbus protocol.
As shown in formula (3), the total energy consumption F of the computer room in colleges and universities is composed of the energy consumption of main equipment Q1, the energy consumption of air conditioning system Q2, the transmission equipment Q3, the DC power cabinet Q4, and the other equipment Q5. (3) F = Q1 + Q2 + Q3 + Q4 + Q 5
BatteryMon is a reliable tool for this purpose that not only shows the estimated remaining laptop battery, but also allows you to track usage and consumption. Open the app, and click on the Start graphing button in the top-right corner to start tracking. It will show a graph with a plain line and a dotted line.
Laptop battery estimates are calculated using a combination of hardware and software working together. Battery Management System (BMS) is an electronic control system inside batteries that tracks battery health, current draw, temperature, state of charge (SoC), etc., and reports it to the operating system.
At present, most of China's computer room energy consumption evaluation index adopts the first type, and its value is formula (4) shows: (4) PUE = F Q 1 That is the ratio of the total energy consumption value of the computer room to the energy consumption of the computer room's main equipment.
A battery room is a room that houses batteries for backup or uninterruptible power systems. The rooms are found in telecommunication central offices, and provide standby power for computing equipment in datacenters.
