Mining optical fiber

1.

With the rapid development of the era of artificial intelligence and the interconnection of all things, the new era of intelligent mine is really coming. With the rapid pace of 5g technology commercial, a large number of related applications are also ready to come out, 5g technology is also applied to unmanned mining equipment, and graally become a reality

The age of

5g is coming, although the intelligence is very good, the artificial can not be completely replaced

The cost of setting up 5g base station is also very high, because 5g base station itself is not connected by wireless, it is still connected with the operator's server through optical fiber. So where the 5g base station is built, the optical network will be laid. Some cities are lucky to say that a backbone optical fiber can provide network services for hundreds of thousands or even millions of people. But in remote mines, the cost of laying a fiber-optic network is relatively high. In particular, some mines are not only remote, but also have dangerous terrain, and some even have no roads, which brings great difficulties to the erection of 5g base stations

therefore, if we want to use 5g for mining, the initial investment cost is very high, and not all units can afford it. Of course, there is also a technical solution is to establish 5g LAN, 5g is only used for short-distance communication, and does not need to connect to the external network. Of course, this requires remote control personnel to be close to the mining site. Although there are some restrictions, it is safer than traditional mining methods

in general, the technology of mining with 5g remote control is still at the level of publicity, which is far away from the actual application. Of course, if 5g network is spread all over the country in the future, 5g can be used everywhere to access the Internet, and the cost of use is also reced, then the technology of remote control of construction machinery will certainly be more practical

2. It's hard to say. After a few days of practice, I found that this has little to do with the 100m optical broadband speed. I'm a 50m optical broadband, and the average upload and download speed is between 4m and 6.5m. The network cloud, QQ mailbox and thunderbolt download can basically be stable at the upload / download symmetric transmission 5m / s, which is about the nominal broadband speed of 50Mbps. However, the crystal miner's speed is really slow. I feel that it is limited. The upload speed is 20kbps at the lowest and 3000kbps at the highest, which is about 2k-300k per second. 300K is the limit measured in recent days!!! The crystal square mainly depends on uploading data to earn crystal, one crystal needs to upload 4m data. According to the actual upload speed of 300K, it takes about 14 seconds for 4m data, 10000 crystals for 1 yuan, that is, it takes 560000 seconds, about 156 hours for 40000m traffic, and it takes about a week to earn 1 yuan. The premise is to ensure the highest network speed in the whole process

the advertisement said that it was a zero cost way to make money. I tested it with i7 computer and netbook respectively, and the broadband was 50m symmetrical optical broadband. At the same network speed, the number of i7 computer connections is about 20, and the maximum upload speed can reach 3000kbps, but the network speed is not always constant. The number of connections is about 3-6, and the network speed is about 50-60kbps
computers and broadband are the costs that users need to invest in in the early stage
in the follow-up, there are also electricity and time, which are relatively hidden costs. At present, poor miners can't earn any electricity bills_ T

3. Now ordinary broadband users dial-up Internet access mode, up and down network speed is inconsistent, up speed operators are limited. If the uplink rate is required, the fixed IP line optical broadband can be handled by the operator. There is no limit to the uplink rate of this broadband, and the uplink and downlink rates are the same. The price is higher.

4. This has some impact
not big.

5. Buy the router or layer-3 router switch that supports multi dialing (ask the customer service whether it can realize this multi dialing function before buying) and then configure it to realize single broadband multi dialing

6. There is a difference between the deposit of ICBC and the futures and spot of the market. The latter two are the result of market regulation, while the former is the result of the formulation of national macro policies. In short has the final say that the state has the final say, and the latter is the market. But the market price has a certain influence on the pricing of the country. At the same time, the state will also decide to put gold into the market or to store gold in the market according to the changes in the market.

7. The rise and fall of gold price in London, the change trend of gold price is the result of many factors in the market, comprehensive game, it is quite complex, but also particularly simple. As far as single factor is concerned, there are four factors influencing the trend of gold price:
1. The trend of US dollar. The exchange rate of US dollar is one of the important factors influencing the fluctuation of gold price. Generally, there is a negative correlation between the trend of US dollar and that of gold. However, both are "hard currencies" in the world. They buy US dollars in times of peace and prosperity and gold in times of war. When people take gold, they will give up dollars. When they take dollars, they will give up gold. This means that if the trend of the US dollar is strong and there is a great opportunity to invest in the appreciation of the US dollar, people will certainly tend to the US dollar. The weaker the dollar is in the foreign exchange market, the stronger the gold price will be
2. During the period of war and political turmoil, gold has always been regarded as a kind of safe haven investment. One of the reasons is that in the period of war and political turmoil, the increasing demand for gold will stimulate the rise of gold price
3. World financial crisis when the financial system of the United States and other Western powers is unstable, the world's capital will be invested in gold, and the demand for gold will increase, and the price of gold will rise. At this time, gold played the role of a cash haven. On the contrary, when the financial system is stable, investors' confidence in gold will be greatly reced and the gold price will fall.
