The miner was cut off

1. There are three ways to query before and after the power failure.
1. Call 95598 power service hotline and operate according to voice prompts.
2. Search the website of the region (State Grid), Click [service and support], [power service], [power outage announcement] - fill in [region] - [start and end time], fill in [power outage range], and click [query]
3. The ways to view power outage information by wechat are as follows:
1. Open wechat and pay attention to the local state grid power company
2. Click to enter official account. If there is no binding user, you can bind the user, point my electricity, and then click the number of the house.
3. To view the power failure information, click public information, and then click power failure information
4. official account will send you a message, click to view;
5. Finally, you can see the power failure information. If the area is not right, you can choose the right area.
note:
if the area is often power failure, it is recommended to buy a generator set for standby. For the family, gasoline generator is OK. If the power of the family is more than 10kW, diesel generator is more cost-effective, and the generator set is noisy, Can choose silent diesel generator is good, gasoline generator sound is smaller, basically do not use a quiet box
for the standby power generator set used by enterprises, it's good to choose diesel generator. It can be used, silent diesel generator set, or automatic diesel generator set. Automation can be started automatically. When the power supply stops, the diesel generator set can be started automatically, which is very convenient.

1、 mining principle

at the beginning, we could dig bitcoin with the computer CPU. The founder of bitcoin, Nakamoto Tsung, g out the world's first creation block with his computer CPU. However, the era of CPU mining has long passed, and now bitcoin mining is the era of ASIC mining and large-scale cluster mining

looking back on the mining history, bitcoin mining has gone through the following five times: CPU mining → GPU mining → FPGA mining → ASIC mining → large-scale cluster mining, The mining speed changes are as follows:

CPU (20mhash / s) → GPU (400mhash / s) → FPGA (25ghash / s) → ASIC (3.5tash / s) → large scale cluster mining (3.5tash / s * x)

mining speed, which is called computing power in professional terms, that is, the ability of computer to generate hash collisions per second. In other words, how many hash collisions can our miner do per second is the calculation force. Computing power is the ability to dig bitcoin. The higher the computing power, the more bitcoin you dig, the higher the return

in the world of bitcoin, a data block is recorded about every 10 minutes. All mining computers are trying to package the data block and submit it, and the person who successfully generates the data block will get a bitcoin reward. Initially, bitcoin rewards of 50 bitcoins could be generated about every 10 minutes. But the payment is halved every four years, and now the bitcoin network can generate 25 bitcoins every 10 minutes

to successfully generate data blocks, miners need to find the effective hash value. To get the correct hash value, there is no shortcut. You can only guess. The process of guessing is the process of computer random hash collision. If you guess correctly, you will get bitcoin

Mining method: from a miner to a large-scale mine, you need to prepare a miner, a computer that can connect to the Internet, an AUC, a raspberry pie, power supply and all kinds of connecting lines, etc. The connection order of various devices is network cable - & gt; Raspberry pie - & gt; Microusb cable - & gt; AUC-> 4Pin cable - & gt; Mining machine and power supply

< EM > Figure 3: Mine Map (scale of tens of thousands of mining machines) < / EM >

nowadays, the profit space of small and medium-sized absenteeism who take one mining machine home or deploy a small family workshop (dozens of mining machines) is very limited, and the mining instry is graally concentrating on enterprises and teams with low-cost power resources and professional deployment ability

there are many factors that affect the mining revenue, such as the performance and power consumption of mining machinery, the computing power and difficulty of the whole network, the deployment and operation and maintenance capacity of the mine, the availability of low-cost electricity resources, and the currency price and policy guidance, etc. At present, excellent mining enterprises have the ability of chip research and development, a lot of computing power, professional mine deployment and operation experience, etc. in the future, resources and computing power will be more and more concentrated in these mining enterprises

2. Mine pool

in addition to the above equipment, you also need a necessary tool - mine pool. The function of the mine pool is to gather a large amount of mineral computing power, increase your probability of getting bitcoin, and at the same time, distribute your future bitcoin income to your account in advance

the simple explanation is as follows: now the bitcoin network generates a block every 10 minutes, which contains 25 bitcoins. Suppose there are 1W people in the world participating in mining, then in these 10 minutes, only one lucky person has taken these 25 bitcoins, and the others have nothing. The principle of the mine pool is that everyone mines in teams and distributes according to the agreed distribution method, so that the income of the miners' bitcoin tends to be stable and the risks of the miners are reced. Let's take the most common PPS allocation method as an example. Suppose that your computing power is 10t, and the computing power of the whole mine pool is 100t. Your computing power accounts for 1 / 10 of the total computing power of the mine pool. Suppose that the mine pool can generate 10 bitcoins a day, then you can get 1 bitcoin a day

3. Cloud computing power

in reality, the supply of mining machines often exceeds the demand, and at the same time, the delivery of mining machines needs a long waiting period. Miner installation, commissioning, maintenance and other processes are very complex, which requires a lot of energy. Miners have to enre the noise and heat of miner. For miners, the biggest cost is not these, but the high electricity charges consumed by mining. The profit space of small and medium-sized miners is getting smaller and smaller, even negative

Mining income and risk mining income can be calculated by the following formula:

Mining income = generated bitcoin * currency price - mining machinery cost - electricity fee - custody fee

if you are just a small miner, generally you only need to dect mining machinery cost and electricity fee

Mining risks are as follows:

at present, the number of bitcoin is less than 4.5 million. If we do not issue additional bitcoin, the price of bitcoin will fluctuate, and the price callback will lead to the extension of the payback cycle

mining difficulty improvement at present, our machines can meet the market demand

1. First of all, connect the network cable, plug the network cable into the network cable interface of the mining machine, and remember to plug it tightly. Only when the miner is connected to the Internet, there is no limit to the broadband

extended data

users can buy bitcoin, at the same time, they can also use computers to "mine" bitcoin according to a large number of calculations. When users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, then they will get 25 bitcoins

e to the decentralized programming adopted by the bitcoin system, only 25 bitcoins can be obtained every 10 minutes, and by 2140, the maximum number of bitcoins in circulation will reach 21 million. In other words, bitcoin system is able to achieve self-sufficiency, resist inflation through coding, and prevent others from destroying these codes

7. It won't be lost, as long as your account number and password are not lost. It's just that there's no electricity, and the bitcoin you get from mining can't be transferred

did you use the Avalon miner?

8. Installation of ant protection board app, only support Android protection board calibration:
1. Unit voltage calibration: by adjusting the "system reference voltage" (about 3.0 by default), slowly increase and decrease the amplitude of 0.001, the unit voltage value can be changed until it is accurate! 2. Total voltage calibration: by adjusting the "total voltage ad value into the actual voltage of the parameters" (default about 3330), slowly adjust the size of this value, you can change the total voltage until accurate! 3. Current calibration: by adjusting the "current sensor range", slowly adjust the value, you can change the current until it is accurate
note: please do not change the item of "power starting current" in parameter setting, too large may lead to MOS tube burning and discharging!!!
