Description

Solar module right confirming system and method

Technical Field

The invention relates to the technical field of block chains, in particular to a solar module right confirming system and method.

Background

Solar energy may present an explosive construction requirement as one of the most important power generation methods in new energy. In the next five years, the number of the centralized photovoltaic power stations and the distributed photovoltaic power stations is estimated to be more than 2 times of the number of the centralized photovoltaic power stations and the distributed photovoltaic power stations; in the next 10 years, the installed capacity of the centralized and distributed photovoltaic power stations is more than 4 times of the existing capacity.

However, in the existing power station construction, a construction party is generally required to obtain the power station construction approval right in advance, arrange capital, purchase a photovoltaic module and an inverter, and enter operation for 25 years after the construction is completed. During this period, the corresponding invested funds will be used as investment lock, and only the benefit can be gradually obtained through the later lean operation. Certainly, the power station supplier can sell the power station to realize fund withdrawal.

For example, a 1MW photovoltaic power station is built at an investment cost of about 300 ten thousand, which means that a purchaser needs to pay 300 thousand of funds to complete purchase, and the large amount of funds demand limits the range and quantity of the purchaser. In the construction of a photovoltaic power station, a group string needs to be assembled by components, and a plurality of groups are connected in series and parallel to form the power station. The single component is about 500w in the current market, and the number of the components in the 1MW photovoltaic power station is 2000. If the power station is sold at the minimum unit, i.e., component level, the cost per component is about 1500 dollars, and the number of purchasable persons for the power station is greatly increased.

However, independent photovoltaic power stations can be bought and sold because the photovoltaic power stations have property ownership and can be certified and traded by a national authority, and the related rights and interests of purchasers can be guaranteed.

The module is the minimum unit of a power station at present, and a solar module monitor is generally adopted to monitor an independent module in real time to obtain real-time generated voltage, current, power and electric quantity, and the real-time generated voltage, current, power and electric quantity are sent to a monitoring center through a response communication means; the solar component optimizer is adopted to monitor the power generation condition of the components in real time, and the whole string of power generation conditions are combined to be matched with the inverter to achieve improvement of the whole string of power generation efficiency. However, the real-time data collected in the existing detector and optimizer technology cannot realize the legal metering effectiveness firstly because the data cannot be approved by an authority and is difficult to be picked up by other interested parties without calibration; secondly, the existing data are all forwarded to a self-owned data system or a low-trust degree system, so that whether the data are strongly managed or not can not be proved, and the data are ensured not to be modified. Therefore, the solar energy component is not certified (has independent property right, registers and makes a book, and identifies the belonger of the article, provides full protection) temporarily, and cannot enter the transaction.

Detailed Description

The present invention will be described in further detail with reference to examples and embodiments. It should be understood that the scope of the above-described subject matter is not limited to the following examples, and any techniques implemented based on the disclosure of the present invention are within the scope of the present invention.

In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, are not to be construed as limiting the present invention.

As shown in fig. 1, the present invention provides a method for authorizing a transaction of a solar module, which specifically comprises the following steps:

s1: the intelligent terminal is corrected by adopting an intelligent terminal self-correction technology, and the intelligent terminal meeting the correction requirement is selected for data acquisition, so that the reliability of data acquisition of the intelligent terminal is improved.

In this embodiment, when the data is collected by using the intelligent terminal, the correctness of the data cannot be guaranteed, and the intelligent terminal may be modified so that the data may have a problem unless the intelligent terminal is manufactured by an authority organization or is supervised by the authority organization, and the authority organization is adopted to verify and provide authority guarantee. However, such a method may exceed the scope of the authority service, and brings challenges to the work of the authority; and secondly, the intelligent terminal which is subjected to supervision, manufacturing and verification by an authority is likely to be high in price, and the practical value of the intelligent terminal is lost.

S1-1: the method comprises the steps of simultaneously collecting the same data by adopting at least two intelligent terminals, carrying out statistical distribution calculation on the data collected by each intelligent terminal, and drawing a statistical distribution graph as shown in figure 2. When the existing data anomaly analysis method (such as the Grasbus method, the Dixon method, the skewness-kurtosis method, the Lauda method and the Nall method) is adopted to find out the data with larger deviation, the intelligent terminal corresponding to the data with larger deviation is subjected to 'yellow marking' or 'black marking', or the current grade of the intelligent terminal is determined to be a low value, and the other intelligent terminals with smaller data deviation can be considered to meet the requirements, and meanwhile, the intelligent terminal can be endowed with a high value.

As shown in fig. 2, for example, when data is collected and a statistical distribution map is drawn by using the intelligent terminals respectively numbered A, B, C, D, E, F, G, it can be seen that the data distribution of A, B, C, D, E, G is even, and if the data deviation of F is large, the intelligent terminal numbered F is treated by "marking yellow" or "drawing black" to be assigned with a low value, and the intelligent terminal numbered A, B, C, D, E, G is assigned with a high value.

The benefits of assigning a score are: in an occasional test, the intelligent terminal which passes the test last time can not be proved to always meet the requirement, and the intelligent terminal which does not pass the test last time can not pass the test in the test, so that when the next round of test is carried out, all the intelligent terminals are still subjected to irregular test on the same standard data, statistical distribution calculation is carried out, assignment is carried out on the terminals only again, and the intelligent terminals which are lower than the preset score are removed after a plurality of tests.

In this step, in order to improve the reliability of the intelligent terminal, the method further includes S1-2:

the platform issues a random selection question to the intelligent terminals, all the intelligent terminals perform edge calculation and answer in a rush mode, only the intelligent terminals which answer quickly within a specified time (less than or equal to the specified time) can be used as alternatives, the intelligent terminals which are used as the alternatives can collect data, and the intelligent terminals which exceed (are greater than) the specified time are removed.

In this step, in order to improve the reliability of the intelligent terminal, the method further includes the following steps of S1-3:

a self-checking hardware circuit is built in the intelligent terminal, the platform issues an instruction and converts the instruction and then outputs an analog or digital parameter to the self-checking hardware circuit, then an output value of the self-checking circuit is collected by a chip in the intelligent terminal and fed back to the platform, and the platform can judge whether the intelligent terminal is tampered or not by using the returned output value (for example, the output value is compared with a theoretical value, the comparison is correct, and the comparison is incorrect). Once a smart terminal is found tampered with, the smart terminal is "rejected".

S2: and directly chaining the data acquired by the intelligent terminal to improve the reliability of the data.

S2-1: a blockchain system for endorsement of authorities can be established, collected data (such as real-time power generation voltage, current, power, electric quantity and the like) are kept consistent among a plurality of nodes through a consensus algorithm, and each authority provides trust endorsement, so that the blockchain system has higher trust degree and provides a bottom layer basis for subsequent assembly asset authority confirmation.

Further comprising S2-2: the block chain prediction machine is constructed, data are directly collected at a data source head end (solar component), and the collected data are subjected to individual signature by adopting signature or related technology, so that on one hand, the right of the data is confirmed, and on the other hand, in case of data problems, the data can be traced and accountable.

In this embodiment, the blockchain prediction machine is an intelligent terminal, and a blockchain algorithm is built in the blockchain prediction machine, so that own private key, public key and wallet can be calculated and stored in the blockchain prediction machine. The block chain prediction machine collects external physical and actual related data, combines algorithms such as signature and the like, and sends the collected data to the block chain without tampering by executing an intelligent contract on the block chain, and the whole process is free from manual participation, so that the block chain prediction machine has the functions of automation, accuracy and tracing.

In the step, the collected data are subjected to chain linking, so that the possibility of data tampering is avoided, and the reliability of the data is improved.

S3: the solar module is fused with the authority ID, so that the solar module asset has legal effectiveness, and the module asset circulation is promoted.

In this embodiment, the solar module is authorized to participate in marketized transaction, the intelligent terminal is not tampered in S1, the data in S2 is directly linked to the platform layer and is not tampered, and the transaction of the solar module with the user is not enough supported, and the transaction behavior of the user needs to be legally approved, that is, in the house transaction process, after the house is traded from a to B, the property right change needs to be performed in the national house registration center, and the change can be legally approved.

S3-1: the solar component relies on an 'industrial identification analysis' system of the national Ministry of industry and communications, a unique ID of the solar component is declared, the ID is bound with the solar component and is kept unchanged in the property trading process, only the relevant information of an owner is changed, and legal transfer is realized.

S3-2: based on a domestic top-level authoritative block chain system or an international authoritative block chain system (such as a safe bank, a American group, a Shunfeng stock control, a Jinyi technology, an eastern wealth and the like), a unique block chain address is obtained in the system and is in one-to-one correspondence with the solar modules (can be a unique block chain wallet address), relevant information such as a private key, a public key, an address and the like of the block chain address can entrust management of the authoritative block chain or the international authoritative block chain system, credit of the authoritative block chain system is used for endorsement, and when the module ownership is transferred, uplink data is used for realizing ownership transfer certification.

In this embodiment, the idea of the technical scheme can be applied to other fields, such as data recording and non-tamper feature utilization in the transfer process of the usage right of the shared energy storage device (charger); for example, in the battery use right transfer in the battery replacement of the electric automobile, the related data are linked and the right transfer is proved; if the shared bicycle or the shared automobile is used by the renter, the use right is transferred to the next user by the previous user or transferred to the user by the renting company, and the data in the period can be proved, and the use right can be proved to determine the transfer; and similar methods can be adopted for realizing the use ownership transfer like the renting of the cabinet and the server in the IDC machine room.

As shown in fig. 3, based on the above method, the present invention further provides a solar module right confirming system, which includes an intelligent terminal calibration unit, a data uplink unit, and an ID binding unit.

In this embodiment, the intelligent terminal correction unit includes a data anomaly analysis module, which is used to find data with large deviation.
