Mining machine power adjustment method
Disclosed is a mining machine power adjusting method, including: when a mining machine is in a working stage, collecting an input voltage of the mining machine; adjusting a maximum working power of the mining machine to a first power value by controlling a working frequency and an output voltage of the mining machine when the input voltage is lower than a pre-determined voltage threshold; and adjusting the maximum working power to a second power value by controlling the working frequency and the output voltage of the mining machine when the input voltage is higher than or equal to the voltage threshold, where the first power value is the product of the input voltage multiplied by a rated current of the mining machine, and the second power value is the product of the voltage threshold multiplied by the rated current. According to the disclosure, the power of the mining machine is adjusted according to changes in the input voltage by fully utilizing a voltage range slightly higher than a standard input voltage, so that the calculation power of the mining machine can be greatly increased to achieve better mining revenues without significantly increasing the power consumption ratio of the mining machine while ensuring the stable and safe running of the mining machine.
