How to Calculate Energy Usage on Lincoin IoT Management System #
The Lincoin ASIC Management System employs a three-layered approach to calculate energy usage, ensuring the highest accuracy depending on the available data sources. This guide outlines the methods used for issuing or auditing hosting bills.
Layer 1: Smart PDU Energy Usage #
If a Smart PDU is available, it is the most accurate method for measuring energy consumption. The Smart PDU directly monitors and records the power usage of each connected device.
- Direct Measurement: Energy usage data is continuously captured and can be accessed via the Smart PDU’s management interface.
- Example: If the Smart PDU reports 150 kWh for an ASIC over 24 hours, this exact value is used for billing.
Layer 2: Software Interface of ASICs #
If a Smart PDU is unavailable, we rely on the energy data provided by the ASIC’s software interface. This method applies to miners like the MicroBT Whatsminers, who automatically report their energy consumption.
- Whatsminer Example: The software interface of a Whatsminer M30S might report 120 kWh usage, which would then be used in our calculations.
Layer 3: Energy Usage Calculation for Antminers #
For all Bitmain Antminers, such as the S21 and S19, which do not provide direct energy usage data through their software interfaces, we calculate the energy usage based on the device’s hash rate, efficiency rate, and run-time duration.
- Formula:
- Power (kW):Power (kW)= (Hashrate (TH/s)×Efficiency (J/TH))
- Energy Usage (kWh): Energy Usage (kWh)=(Hashrate (TH/s) × Efficiency (J/TH)) × Run-Time (hours)
- Example: For a Bitmain S21 running at 200 TH/s with an efficiency of 17.5 J/TH:
- Power: Power=200×17.5=3500 W | kW=3.5
- Energy Usage (24 hours with 100% uptime): Energy Usage=(200×17.5)×24=84 kWh
By implementing a layered approach using Smart PDU data, ASIC software interface readings, and calculated estimates for Antminers, the Lincoin IoT Management System ensures energy usage is measured with the utmost accuracy. This approach allows for transparent and reliable billing tailored to the specific infrastructure and equipment.
