Abstract

Embodiments of the present invention provide a method and device for starting a digital currency mining machine, and a digital currency mining machine. The digital currency mining machine includes N hash boards connected in series to form a series power supply structure, the positive terminal of the power supply of the first hash board in the series power supply structure is connected to the positive terminal of the power supply, and in the series power supply structure The negative terminal of the power supply of the last computing power board is connected to the negative terminal of the power supply, and each computing power board includes a plurality of computing chips, wherein N is a positive integer of at least 2; the method includes: before turning on the power supply , sending a starting signal to the refrigeration unit of the mining machine; turning on the power supply; controlling each computing chip in the N computing power boards to start the core synchronously in a gradual manner. The implementation of the present invention improves the voltage balance between the hash boards and inside the hash board, and can also ensure the accuracy of the clock signal.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular relates to a method and device for starting a digital currency mining machine and the digital currency mining machine. Background technique [0002] With the rapid development of supercomputers, digital currency mining machines have gradually moved from graphics card mining machines to application specific integrated circuit (ASIC) mining machines with lower power consumption and lower cost. [0003] A digital currency mining machine usually contains multiple hashboards. In order to improve the computing power, the computing power board is generally a circuit board arranged in a chip array. Usually, the hash board is a computing array unit composed of several computing chips (such as ASIC, CPU or GPU). The core voltage power supply of the computing chips in the computing power board mostly adopts a series power supply mode, in which the positive power supply of the comput...

Problems solved by technology

[0004] However, with the gradual increase in the computing power demand of the mining machine, the power of the mining machine is getting higher and higher, the output current of the power supply is getting larger and larger, the power output loss proportional to the square of the current will increase sharply, and the power supply efficiency will decrease

[0005] Moreover, the power supply needs to provide a lower voltage (for example, 12 volts or 18 volts) for each parallel-connected computing power board, so a DC-DC (DC-DC) device needs to be arranged in the power supply to achieve step-down, resulting in cost question
