New energy and blockchain

1. I didn't see any specific solutions to the practical problems
on the contrary, it's like taking advantage of the hot spots to catch a wave of people's feet.

2. The integration of energy and blockchain can promote the independent transaction between users, rece the burden of electricity charges, improve the transparency and credibility of transaction, rece the transaction time, and improve the utilization rate of energy through the inter community renewable energy transaction network established by using distributed ledger.

3. In fact, it's very simple to let you have a taste for a few days. In fact, it costs dozens of yuan to hang up for one day. When the number of people recharged reaches a certain number, the website will be closed. To put it bluntly, it's a liar

4. NEC new energy blockchain coin is a circulation token in the main network based on blockchain technology, which aims to serve the new energy network ecology. It has the characteristics of decentralization and can not be tampered with. The ownership belongs to the holder. In the application of Nen chain ecology, NEC new energy blockchain currency will bring greater application scenarios in the field of new energy vehicles, black technology procts, AI smart life, 5g, Internet of things, etc. With the further improvement of ecology, it is accepted and recognized by more people through interconnection and interactive use.

5. At present, the concept and construction mode of blockchain has been relatively mature, and some progress has been made in the field of application analysis of energy utilization. Specific applications include: energy trading and supply based on smart contract, ownership of information and establishment of distributed transaction records, etc.

6. What is the significance of trading new energy with blockchain? The report said that the two major supports for the application of the technology, namely digital bill of lading and smart contract, can greatly improve the execution efficiency of crude oil trading and optimize the transaction financing cost by 20% - 30%
according to the general definition, a blockchain is a series of data blocks generated by association using cryptographic methods. To sum up, blockchain technology has seven characteristics: trust relationship established by pure mathematical method, decentralized structure (high operation efficiency, low operation cost), complete and transparent data information (in line with the law and easy to track), distributed accounting and storage (high fault tolerance), programmable intelligent contract (no burden evolutionary model), and high reliability, A global database (highly inclusive business model), anonymity (Privacy Protection) behind the transparent world.

7. The problem of distributed access to the Internet has been solved. Now the power grid is basically centralized, while the blockchain is decentralized, which is consistent with the current photovoltaic power generation. Photovoltaic power generation is decentralized and multi-point.. The access to the power grid is uncertain and its performance is unstable, or some intervention may damage the power grid. In the algorithm of blockchain, there is consensus algorithm, which can solve this problem well,

8. Blockchain technology new energy is a concept plate for speculation in stocks
is the hot spot, stir fry the hot spot, stir fry the hot spot

a treasure search support resistance simple time-sharing, plate time-sharing let you throw high low suction artifact, good or not, always have to try to know

9. CPRI rate = sampling rate × Data bit width × 2IQ × Number of antennas × Carrier number × 10/8 × 16 / 15), of which CPRI wire weaving efficiency is 8 / 10; CPRI frame efficiency is 15 / 16
explain the relevant parameters:
sampling rate: the number of sampling points in 1s, for example, 30.72m sampling rate is used for LTE 20m bandwidth. Data bit width: for LTE TDD, in the case of uncompressed CPRI, the downlink 15bit and uplink 12bit IQ: the value is fixed to 2
in the transmission, the signal vector is decomposed into two components with the same frequency and the same peak amplitude, but the phase difference is 90. It is usually described by a sine signal (Q component) and a cosine signal (I component)
IQ signal is a two-way signal with orthogonal phase, which is designed by the molation input to improve the frequency band utilization
line coding efficiency: CPRI performs electro-optical conversion, and the conversion efficiency is 80%, i.e. 8 / 10
CPRI frame efficiency: CPRI has control word overhead, which accounts for certain transmission resources, so the effective efficiency is 15 / 16 (Note: the following is the conversion from the actual rate to CPRI rate, so it is just the opposite, multiply 10 / 8 and 16 / 15)
take the MIMO of 20m LTE single carrier cell as an example, the sampling rate = 30.72m, Data bit width = 15bit (uncompressed CPRI), antenna number = 2, carrier number = 1, CPRI rate = 30.72m * 15 * 2 * 2 * 1 * 10
16 / 15 = 2457.6m, that is to say, when al antenna MIMO transmits a LTE 20m cell, it needs at least 2.5G optical mole.
