Starting method and device of digital currency mining machine, and digital currency mining machine

Abstract

The embodiment of the invention provides a starting method and device of a digital currency mining machine, and the digital currency mining machine. The digital currency mining machine comprises N computing power boards which are connected in series to form a series power supply structure, a power supply positive terminal of a first computing power board in the series power supply structure is connected with a positive terminal of a power supply, and a power supply negative terminal of a last computing power board in the series power supply structure is connected with a negative terminal of the power supply, wherein each computing power board comprises a plurality of computing chips, and N is a positive integer which is at least 2; the method comprises the steps of before a power source isstarted, sending a starting signal to a mining machine refrigeration part; turning on the power supply; and controlling each operation chip in the N computing power boards to synchronously open the core in a progressive manner. According to the method of the invention, the voltage balance between the computing power boards and in the computing power boards is improved, and the accuracy of clock signals can be ensured.

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
