S306, transmitting the resource allocation data and the resource payment data to a payment service system so that the payment service system transfers resources between an account of an energy supplier and an account of an energy user based on the resource allocation data and the resource payment data;

specifically, after resource allocation data of an energy supplier and resource payment data of an energy user are automatically determined through an intelligent contract, a payment service system is automatically triggered to complete resource transfer between the energy supplier and the energy user;

wherein, the resource payment data may include: the energy consumption rate that the energy using party needs to pay to the energy supplying party, and the resource allocation data may include: energy source supplier can charge energy profit fee to energy source user; specifically, the payment service system transfers the digital resources in the account of the energy user according to the resource payment data, that is, after the resources are transferred between the account of the energy provider and the account of the energy user, the digital resources in the account of the energy user are the original remaining resources minus the energy consumption cost; correspondingly, the payment service system transfers the digital resources to the account of the energy supplier according to the resource allocation data, namely after the resources are transferred between the account of the energy supplier and the account of the energy user, the digital resources in the account of the energy supplier are the original residual resources plus the energy profit cost.

In one or more embodiments of the present specification, resource payment data of an energy user and resource allocation data of an energy supplier are automatically determined based on energy metering data collected in real time by an energy metering data system and uploaded to a blockchain by using blockchain technology and intelligent contracts, thus, the automatic determination of the resource payment data and the resource allocation data and the automatic completion of the resource transfer processing under the multi-party witnesses can be ensured, the determination reliability of the resource payment data and the resource allocation data between the energy using party and the energy supplying party and the safety of the resource transfer process are improved, the resource payment of the energy using party is completed aiming at the use condition of the comprehensive energy by adopting a refined control mode, the resource allocation among a plurality of energy supplying parties is completed aiming at the supply condition of the comprehensive energy, and further, the resource transfer between the energy using party with high safety and high reliability and a plurality of energy supplying parties is realized.

Furthermore, in consideration of ensuring the security of the energy metering data, the server corresponding to the energy metering data system is deployed in an internal machine room, the network to which the server corresponding to the energy metering data system is connected is an intranet network, and the energy metering device uploads the collected energy metering data to the energy metering data system through the internal network, so that the energy metering data received by the energy metering data system from the energy metering device is only checked by an intranet user, and an external user cannot acquire the energy metering data of the energy supplier or the energy metering data of the energy consumer, therefore, in order to transmit the energy metering data of the energy supplier and the energy metering data of the energy consumer to the external internet on the premise of ensuring the security of the energy metering data, the resource payment data of the energy consumer and the resource of the energy supplier are automatically determined by using a block chain technology and an intelligent contract Distributing data, wherein the block chain comprises at least one first block chain node, the first block chain node is the same as the deployment area of a server corresponding to the energy metering data system, namely the first block chain node is deployed in an internal machine room of an energy information center where the energy metering data statistical server is located, and a firewall is arranged between the energy metering data system and the first block chain node;

correspondingly, in step S302, acquiring energy supply metering data of the energy supplier and energy consumption metering data of the energy consumer specifically includes:

the first block link point acquires energy supply metering data of an energy supplier and energy utilization metering data of an energy user, which are uploaded by the energy metering data system through the firewall.

Specifically, because the networking network segment of the server corresponding to the energy metering data system is an intranet segment, the intranet data of the energy enterprise is safely isolated, and an external user cannot directly inquire the energy metering data on the energy metering data system, a first block chain node is arranged in a deployment area where the server corresponding to the energy metering data system is located, wherein the deployment area can be an internal machine room where the server corresponding to the energy metering data system is located, the networking network segment of the first block chain node is arranged as an external network segment of the deployment area where the server corresponding to the energy metering data system is located, namely a network connected with the first block chain node is the internet, and a firewall is arranged between the energy metering data system and the first block chain node, so that the firewall technology can be utilized to selectively transmit the energy metering data related to energy payment cost determination and energy profit allocation determination in a single direction through the firewall And the required energy metering data is transmitted to the Internet from an internal network connected with the energy metering data system on the premise of ensuring data security, and then the resource payment data of the energy user and the resource allocation data of the energy supplier are automatically determined by using a block chain technology and an intelligent contract.

In order to further ensure the data completeness of transmitting the energy supply metering data of the energy supplier and the energy consumption metering data of the energy consumer from the internal network to the internet, the method further includes, after acquiring the energy supply metering data of the energy supplier and the energy consumption metering data of the energy consumer, which are uploaded by the energy metering data system through the firewall, at the first block link point:

the first block chain link point encrypts energy supply metering data of an energy supplier to obtain encrypted energy supply metering data, and encrypts energy consumption metering data of an energy user to obtain encrypted energy consumption metering data;

and the first block chain link point writes the encrypted energy supply metering data and the encrypted energy consumption metering data into the block chain.

Specifically, after the first block link point acquires the energy supply metering data and the energy consumption metering data through the firewall technology, the energy supply metering data and the energy consumption metering data are not directly written into the block chain, the energy supply metering data and the energy consumption metering data are encrypted firstly, and then the encrypted metering data are written into the block chain.

Furthermore, energy metering data on the energy metering data system is uploaded to the internet from an internal network through first block chain nodes arranged in a deployment area where a server corresponding to the energy metering data system is located, and once the first block chain nodes are abnormal, the energy metering data cannot be uploaded to the internet, so that the high availability of the first block chain nodes is ensured in order to ensure the stability of transmitting the energy metering data of an energy supplier and the energy metering data of an energy consumer from the internal network to the internet, and the energy metering data can be normally transmitted to the block chain even if one first block chain node is abnormal, and on the basis, the number of the first block chain nodes is more than 2 or equal to 2; specifically, the number of the energy metering data systems may be multiple, and at this time, at least two first block chain nodes need to be deployed in an internal machine room where a server corresponding to each energy metering data system is located; for example, the total number of first blockchain nodes in a blockchain may be at least 2n, where n is the total number of energy metering data systems;

correspondingly, the above-mentioned first block chain link point obtains energy supply measurement data of the energy supplier that the energy measurement data system uploaded through preventing the hot wall and the energy consumption measurement data of the energy user, specifically includes:

any target block chain node of the at least two first block chain nodes acquires energy supply metering data of an energy supplier and energy consumption metering data of an energy user, wherein the energy supply metering data of the energy supplier and the energy consumption metering data of the energy user are uploaded by the energy metering data system through a firewall; and the number of the first and second groups,

any target block chain link node in the at least two first block chain nodes synchronizes the acquired energy supply metering data and the acquired energy consumption metering data to other first block chain nodes in a consensus mode.

Specifically, considering that the firewall has a certain load balancing function, a target block chain node can be automatically selected from at least two first block chain nodes by the firewall based on a preset load balancing mode, the energy metering data system is triggered to pass through the firewall to upload energy supply metering data and energy consumption metering data to the target block chain node, and the target block chain node is used for synchronizing the energy metering data to other block chain nodes, so that the stability that the energy supply metering data and the energy consumption metering data are transmitted to the internet from the internal network by the first block chain node can be ensured.

The method comprises the steps that in the process of resource transfer between an account of an energy supplier and an account of an energy user, resource allocation data of the energy supplier and resource payment data of the energy user are automatically determined through an intelligent contract, so that the intelligent contract for determining the resource allocation and resource payment data needs to be deployed in a block chain in advance, and on the basis of the intelligent contract, the block chain further comprises at least a preset number of second block chain nodes, and the second block chain nodes are different from the deployment region of the first block chain nodes; the deployment area of the second block chain node can be an external machine room different from an internal machine room where the energy metering data system is located, the network connected with the second block chain node is the internet, and the energy service providing platform is in communication connection with the second block chain node;

correspondingly, before acquiring the energy supply metering data of the energy supplier and the energy consumption metering data of the energy consumer at the above step S302, the method further includes:

a second block link point acquires a resource transfer data determination template uploaded by an energy service providing platform; the resource transfer data determination template can be generated by the energy service providing platform based on a preset energy charging rule and a preset resource allocation rule;

the second block link point generates an intelligent contract for determining resource allocation and resource payment data based on the resource transfer determination template, wherein energy charging unit price information in the intelligent contract can be a dynamic parameter, and the energy service providing platform dynamically determines and credibly links the resource according to the energy supply capacity of the energy supplier and the energy utilization requirement of the energy user;

in addition, the resource transfer data determination template includes a plurality of dynamic fields, for example, basic attribute information of the energy supplier or the energy consumer, such as a business name, address information, and business account information, and therefore, the business service system of the energy supplier or the energy consumer is also required to upload the basic attribute information to the second block chaining node in advance, and the second block chaining node updates the plurality of dynamic fields in the resource transfer data determination template based on the basic attribute information, so as to trigger the smart contract generated based on the resource transfer determination template to take effect.

The resource transfer data determination template further includes a plurality of variable parameters, and correspondingly, the intelligent contract for determining the resource allocation and resource payment data includes a plurality of variable parameters, and specifically, based on the acquired energy supply metering data of the energy supplier and the energy consumption metering data of the energy consumer, values of parameters of the intelligent contract deployed in the block chain can be determined, so that the resource allocation data of the energy supplier and the resource payment data of the energy consumer are automatically determined through the intelligent contract.

Specifically, when at least two first block link points deployed in an internal machine room of an energy enterprise data center (i.e., a data service center provided with a server corresponding to an energy metering data system) are unavailable at the same time, resource allocation data of an energy supplier and resource payment data of an energy user can be determined through a second block link point deployed in an external machine room connected to the internet based on energy metering data uploaded to a block chain, so that resource transfer between an account of the energy supplier and an account of the energy user is realized.

Further, for a process of triggering the payment service system to automatically perform resource transfer between the account of the energy provider and the account of the energy user, considering that there may be a case that the payment service system does not access the block chain, if the payment service system is called through the API to complete automatic resource transfer, and the payment service system returns a corresponding resource transfer record to write into the block chain, since the payment service system does not participate in the consensus storage of the resource transfer record, for the payment service system, there may be a case that the resource transfer record in the block chain cannot be certified with confidence, therefore, in order to improve the confidence level of the payment service system on the payment call record stored on the block chain, based on this, the above S306 transmits the above resource allocation data and the resource payment data to the payment service system, specifically including:

and calling a payment service system by using a prediction machine technology, and transmitting the resource allocation data and the resource payment data to the payment service system.

According to the method, the automatic payment settlement is realized for the energy consumption of energy users and the automatic income distribution is completed for the energy supply amount of a plurality of energy suppliers by utilizing a prediction machine technology under the condition that a payment service system does not access a block chain, so that the interface calling record of the payment service system can be recorded by the block chain link point in a trusted manner, and the interface calling record recorded in the block chain can achieve credible consensus between the block chain link point and the payment service system.

Specifically, after the calling the payment service system by using the predictive machine technology and transmitting the resource allocation data and the resource payment data to the payment service system, the method further includes:

and writing the interface call record and the resource transfer record into a block chain.

Specifically, the interface call record may include: the interface call time, the payment service system identifier and other related information, and the resource transfer record may include: and the interface call record and the resource transfer record uplink are used as storage evidence so as to trace and verify the resource transfer process between the account of the energy supplier and the account of the energy user.

In order to effectively manage and control the access operation of the energy metering data in the blockchain, so as to further improve the security of the energy metering data, based on this, before acquiring the energy supply metering data of the energy supplier and the energy consumption metering data of the energy consumer in the above S302, the method further includes:

the second block link point acquires data access authorization information uploaded by the energy service providing platform, wherein the data access authorization information comprises: identification information of an authorized party and/or identification information of authorized access data;

and the second block chain link point writes the data access authorization information into the block chain.

Specifically, for each energy supply enterprise or energy utilization enterprise with energy supply metering data query requirements, real-name registration is performed in advance to join a blockchain alliance, and an energy service providing platform uploads data access authorization information of the energy supply enterprise or energy utilization enterprise needing data access authorization to a blockchain in advance, namely, the access authorization is set for energy supply metering data in the blockchain, so that a subsequent blockchain node judges whether a current data access party has data access authorization or not based on the data access authorization information, and therefore, the data access request of the energy supply enterprise or energy utilization enterprise can be responded on the premise of real-name authorization of the energy supply enterprise or energy utilization enterprise, the safety of the energy metering data is ensured, and the risk that the energy metering data are leaked is avoided.

Specifically, for the condition that the energy service providing platform performs data access authorization on an external user with a data access requirement in advance, after receiving a data access request, automatically judging whether a data access party has a corresponding data access right, and only allowing the external user with the data access right to access the energy metering data in the block chain, so as to improve the access security of the energy metering data in the block chain, based on which, the method further comprises:

The foregoing description has been directed to specific embodiments of this disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Language Description Language), traffic, pl (core unified Programming Language), Cal, jhdware Description Language, langua, mylar, pams, Hardware (Hardware Description Language), langva, Lola, HDL, palmware, Hardware (Hardware Description Language), VHDL (Hardware Description Language), and the like, which are currently used in the most popular languages. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone LabsC8051F320, the memory controller may also be implemented as part of the control logic of the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
