Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart illustrating a transaction method of a smart meter according to an embodiment of the present invention, where the method is applicable to a case where a transaction is performed according to data in the smart meter, and the method can be executed by a transaction device of the smart meter configured at a blockchain node. As shown in fig. 1, the method specifically includes the following steps:
and 110, acquiring current electric energy data of a power consumer from a metering module of the intelligent electric meter according to a preset data acquisition cycle.
The intelligent electric meter comprises a sampling module and a metering module, wherein the sampling module can be used for sampling voltage and current in real time or at regular time, and the metering module is used for receiving the voltage and current value in the sampling module in real time or at regular time and carrying out operation processing on the voltage and current value to obtain data such as power and electric quantity of a power consumer as current electric energy data. The electricity consumers can be residents or enterprises and other users who use electricity. The current electric energy data may include a current power value and a current electric quantity value, the voltage current value obtained by the metering module is the current voltage current value, and the power value and the electric quantity value obtained according to the current voltage current value are the current power value and the current electric quantity value.
The block chain node can acquire the current electric energy data in the metering module according to a preset data acquisition cycle. A data acquisition period is preset, and the period setting can be carried out through IRIG-B (InterRange Instrumentation Group-B, an international universal time code). The IRIG-B clock signal can be demodulated to form a time trigger signal, and a data acquisition period is flexibly set. For example, the data acquisition period may be set to one second, and the block link point may receive the time trigger signal every second to obtain the current power data from the metering module once. And the current electric energy data is stored in the block chain, so that the calculation cost is prevented from being tampered.
And step 120, determining the current settlement cost of the current electric energy data in the transaction settlement period according to the preset transaction settlement period and the target appointed cost, and sending the current settlement cost to the target power generation party by the power supply and utilization party to complete the current transaction of the current electric energy data.
In the transaction of the traditional intelligent electric meter, after the current electric energy data is determined by the metering module, electric quantity calculation is carried out according to the preset fixed electric quantity unit price, and a calculation result is transmitted to a scheduling data network. In this embodiment, before the current transaction, that is, in the last transaction, the unit price of the electric quantity of the current transaction, that is, the target contracted cost, may be determined. For example, the target contract fee is 5 gross money per degree of electricity. The target commitment fee may be a preset fee at the time of settlement of the transaction for the first time. The target commitment fee for each transaction may be the same or different.
The method is characterized in that a transaction settlement period is preset, and the transaction settlement period can be confirmed according to the electric power spot transaction market settlement period and comprehensively considering channel transmission delay time and spot transaction settlement delay time. In this embodiment, the transaction settlement period may be set to a minimum of one second and a maximum of one month, and the accurate time stamp is produced by IRIG-B. And after receiving the trigger signal of the transaction settlement period, the block chain node determines all current electric energy data in the current transaction settlement period as the current electric energy data of the transaction settlement period. For example, if the data acquisition period is 24 hours and the transaction settlement period is 30 days, the block link point acquires the current electric energy data every 24 hours, and when 30 pieces of current electric energy data are acquired, the 30 pieces of current electric energy data are the current electric energy data in the transaction settlement period. The IRIG-B code is adopted to determine the data acquisition period and the transaction settlement period, so that the real-time performance and the accuracy of the transaction are greatly improved.
And calculating the current electric energy data in the transaction settlement period according to the target appointed fee. For example, the current electric quantity value in the current electric energy data can be multiplied by the target appointed fee to obtain the fee to be paid by the power consumer, and the current settlement fee can be obtained. After the current settlement cost is determined, the current settlement cost can be sent to a preset transaction server, the power consumers are deducted, the current settlement cost of the power consumers is sent to the target power generator, and the current transaction of the current electric energy data is completed. The target power generation party and the target appointed expense are determined when the current transaction is the last transaction.
In this embodiment, optionally, determining the current settlement cost of the current electric energy data in the transaction settlement period according to the preset transaction settlement period and the target agreed cost includes: judging whether to perform electric energy transaction settlement at the current time according to a preset transaction settlement period; if yes, determining the current settlement cost of the current electric energy data in the transaction settlement period according to the target appointed cost; wherein the target commitment fee was determined in the previous transaction settlement period.
Specifically, whether the transaction settlement of the electric energy is needed at present is determined according to a preset transaction settlement period. Whether the time difference between the current time and the last transaction settlement time is a preset transaction settlement period or not can be judged, and if yes, the electric energy transaction settlement is determined to be carried out at the current time. If not, the current time is continuously acquired until the time condition of the transaction settlement period is met.
And if the electric energy transaction settlement is determined to be required at the current time, determining the target appointed fee determined in the last transaction, wherein the last transaction is the transaction performed in the last transaction settlement period. At each settlement of a transaction, a target commitment fee is determined as the target commitment fee for the next transaction. And determining the total settlement cost of all current electric energy data in the transaction settlement period as the current settlement cost according to the target appointed cost. The target appointed fee can be the unit price of electric quantity, the current electric energy data can be the total amount of the current electric quantity value in the transaction settlement period, and the current settlement fee of the current transaction can be obtained by multiplying the unit price of the electric quantity by all the current electric quantity values. The method has the advantages that the target appointed expense of each transaction is determined in advance, the electric quantity in a period of time is calculated when the current time reaches the transaction settlement period, the calculation times are reduced, the settlement efficiency of the current transaction is improved, the appointed expense of the current transaction is not fixed, and the flexibility of the transaction is improved.
In this embodiment, optionally, determining the current settlement cost of the current power data in the transaction settlement period according to the target agreed cost includes: acquiring expected electric energy data submitted by a power consumer in the last transaction settlement period; judging whether the current electric energy data in the transaction settlement period is larger than the expected electric energy data; if yes, determining the overdue electric energy data in the current electric energy data according to the expected electric energy data; determining expected settlement cost of expected electric energy data according to the target appointed cost, and determining overdue settlement cost of the overdue electric energy data according to preset punishment cost; and obtaining the current settlement cost of the current electric energy data according to the expected settlement cost and the overdue settlement cost.
Specifically, after each transaction, the electricity consumer can reach an electricity consumption agreement with the next electricity generator for generating electricity, and the agreed electricity generator is the target electricity generator for which the electricity consumer needs to pay electricity charges during the settlement of the next transaction. The agreed electricity utilization agreement can include the target contract fee at the next transaction and the expected electric energy data of the electricity utilization party. The expected power data is power data expected to be used by the power consumer in the next transaction settlement period, for example, the expected power data may include a power value expected to be used by the power consumer in one transaction settlement period. The electricity utilization agreement can also comprise a punishment cost, wherein the punishment cost is the cost for charging the electricity utilization party when the actually used electric energy data of the electricity utilization party exceeds the expected electric energy data. And in each transaction, the power utilization party and the power generation party can submit the achieved power utilization protocol to the block chain link point for block chain storage, so that the power utilization system is convenient to use in the next transaction.
After the electric energy transaction settlement is determined to be needed at the current time, expected electric energy data, target appointment cost, punishment cost and the like submitted by the power consumer in the last transaction settlement period are obtained. And comparing the current electric energy data in the current transaction settlement period with the expected electric energy data, and judging whether the current electric energy data is larger than the expected electric energy data, namely judging whether the actually used current electric energy data exceeds the expected electric energy data. If so, determining the overdue electric energy data in the current electric energy data, for example, subtracting the expected electric energy data from the current electric energy data to obtain the overdue electric energy data. And calculating the expected electric energy data part in the current electric energy data by adopting the target appointed fee to obtain the expected settlement fee of the expected electric energy data part. And calculating the overdue electric energy data part in the current electric energy data by adopting a preset punishment cost to obtain the overdue settlement cost of the overdue electric energy data. For example, for an excess portion of the power data, a penalty cost of a block of money is added for each degree of electricity exceeded. And adding the expected settlement cost and the overdue settlement cost to obtain the current settlement cost of the current electric energy data. The beneficial effect that sets up like this lies in, can obtain the current settlement expense of consumer fast to punishment nature charges to the part of the electric energy data of overlength, avoid the user to abuse the electric energy, be favorable to the energy saving. And the calculated fee is predetermined, the appointed fee of each transaction settlement period can be different, and the transaction flexibility of the intelligent electric meter is improved.
And step 130, determining target agreed fees of the target power generator and the target power generator from at least one candidate power generator based on the preset candidate power generator information according to the current electric energy data of the power generator and the preset expected power consumption information, so as to achieve the trade consensus of the power generator and the target power generator on the next trade settlement period.
After the current settlement fee of the current transaction is determined, a new target power generator and a new target contract fee are determined to be used as the target power generator and the target contract fee of the next transaction. The electricity consumers can preset expected electricity consumption information according to actual use conditions of the electricity consumers, the expected electricity consumption information can be information such as expected electric energy data of the electricity consumers, and the expected electric energy data can include expected power values and expected electric quantity values expected to be used by the electricity consumers in the next transaction settlement period. The block chain may store in advance an intelligent contract for screening a target power generator, and the candidate power generator may store its own power generation conditions into the block chain, where the power generation conditions may include, for example, the maximum power and the maximum amount of power that the power generator can provide. And screening out a target power generator from the candidate power generators according to the current electric energy data and expected power utilization information of the power consumers and the power generation conditions of the candidate power generators. For example, if the expected power value of the power consumer is 500W, the candidate power generators are the first power generator and the second power generator, the maximum power value of the first power generator is 300W, and the maximum power value of the second power generator is 500W, it can be determined that the second power generator is the target power generator. Each candidate power generator can set different appointed fees, and when the power generation conditions of a plurality of candidate power generators meet the power consumption requirement of a user, the candidate power generator with low appointed fees can be used as a target power generator. The power consumer and the target power generator reach a trade consensus, free trade of the power consumer and the power generator is realized, and the fee settlement is carried out according to the trade consensus in the next trade.
The electricity consumers may also negotiate communication with each candidate electricity generator, which is an official electricity generation organization. The consumers can negotiate with the candidate generation parties to obtain satisfactory contract fees. The candidate power generator can determine whether the candidate power generator can supply power for the user in the next transaction settlement period according to the current electric energy data of the power consumers, the preset expected power utilization information and the power generation condition of the candidate power generator. If yes, sending negotiation intention to the power consumer, and negotiating with the power consumer to achieve transaction consensus.
According to the technical scheme, the current electric energy data such as the electric quantity, the power and the like determined by the metering module in the intelligent electric meter are obtained through block link point timing, and the current electric energy data are prevented from being tampered when the cost is calculated. And determining the current settlement cost required by the power consumer for the current electric energy data according to the predetermined target appointed cost, and sending the current settlement cost to the target power generator by the power consumer to complete the current transaction. And then, the target power generation party and the target appointment cost of the next transaction are determined from the plurality of candidate power generation parties, so that the cost can be conveniently paid to the target power generation party according to the appointed target appointment cost in the next transaction. The method and the device realize flexible change of appointed fee of each transaction, and enable the power generation party and the power utilization party to freely perform power transaction. And the electric energy data and the calculation cost are both stored in the block chain, so that the problem that the electric energy data are tampered in the prior art is solved, and the transaction precision of the intelligent electric meter is improved.
Example two
Fig. 2 is a flowchart illustrating a transaction method of a smart meter according to a second embodiment of the present invention, which is further optimized based on the second embodiment. As shown in fig. 2, the method specifically includes the following steps:
and step 210, acquiring current electric energy data of the power consumer from a metering module of the intelligent electric meter according to a preset data acquisition cycle.
And step 220, determining the current settlement cost of the current electric energy data in the transaction settlement period according to the preset transaction settlement period and the target appointed cost, and sending the current settlement cost to the target power generation party by the power supply and utilization party to complete the current transaction of the current electric energy data.
After the current settlement fee of the current transaction is determined, the transaction information of the current time can be recorded. Each user participating in the current transaction can record the transaction information, so that the subsequent verification of the transaction information is facilitated.
In this embodiment, optionally, after determining the current settlement cost of the current power data in the transaction settlement period, the method further includes: recording the transaction information of the current transaction in the whole nodes of the current transaction; the transaction information comprises at least one of current electric energy data, transaction completion time, target appointment cost and current settlement cost, and the whole node of the current transaction is any user node in the current transaction process.
Specifically, the full node is any user node in the current transaction process, for example, the full node may include an electricity consumer node, an electricity generator node, an electricity spot transaction wharf seller, an intermediate related power supply network transmission node, and the like. The transaction information is all information related in the current transaction process, and the transaction information can comprise the number of a power consumer, the number of a target power generator, current electric energy data, transaction completion time, target appointment cost, current settlement cost and the like. The transaction information of the current transaction can be recorded in all nodes of the current transaction, block chain storage is carried out, and data are prevented from being tampered. That is, the whole node records all transaction information of a single transaction, for example, records electric quantity information such as load curve and power vector, and price quote and actual transaction amount accounting information. The block header in the transaction may also be recorded in the light node, and the transaction number and the like may be recorded in the block header as the information of the root node of the mercker tree. The light nodes may be other user nodes in a single transaction that are not involved in the transaction, e.g., the light nodes may be other candidate generator nodes in addition to the target generator. The beneficial effect that sets up like this both can reduce the data memory capacity of light node greatly, can avoid data to be tampered effectively moreover, improve smart electric meter's transaction precision.
And step 230, determining target agreed fees of the target power generator and the target power generator from at least one candidate power generator based on the preset candidate power generator information according to the current electric energy data of the power generator and the preset expected power consumption information, so as to achieve the trade consensus of the power generator and the target power generator on the next trade settlement period.
Each candidate generator may send its own candidate generator information to the block chain for storage, and the candidate generator information may be used to indicate its own power generation condition, for example, the candidate generator information may include the maximum power and the maximum electric quantity value that the generator can reach. The method comprises the steps of storing expected power utilization information in a power utilization direction block chain, determining target power generation parties from candidate power generation parties based on a preset intelligent contract, setting power utilization cost for each candidate power generation party, and taking the power utilization cost of the target power generation party as target appointed cost.
In this embodiment, optionally, determining the target contracted cost of the target power generator and the target power generator from at least one candidate power generator based on the preset candidate power generator information according to the current electric energy data of the power generator and the preset expected power consumption information, includes: determining a power generator to be determined which meets the requirement of the expected power utilization information from at least one candidate power generator according to preset candidate power generator information; the current electric energy data and the expected power utilization information of the power utilization party are sent to the power generation party to be determined, so that the power generation party to be determined can determine whether the requirement of the expected power utilization information of the power utilization party is met; if receiving an acceptance instruction sent by the power generator to be determined, sending the power generation cost preset by the power generator to be determined to the power consumer, and determining whether to accept the power generation cost of the power generator to be determined by the power consumer; and if an agreement instruction sent by the power consumer is received, determining that the power generator to be determined is a target power generator, and the preset power generation cost of the target power generator is the target agreement cost.
Specifically, at least one candidate power generator meeting the requirement of the expected power utilization information is determined from the candidate power generators as the power generator to be determined according to the candidate power generator information and the expected power utilization information of the power utilization. For example, the power generator to be determined that satisfies the power requirement and the electric quantity requirement of the desired electricity utilization information may be determined from the candidate power generators. The current electric energy data and the expected power utilization information of the power utilization party are sent to the power generation party to be determined, and the power generation party to be determined can determine whether the requirement of the expected power utilization information of the power utilization party can be met again according to the actual condition of the power generation party to be determined. For example, if the current electric energy data of the power consumers is far greater than the expected power consumption information, the power generator to be determined may consider that the actual power consumption demand of the power consumers is large, and refuse to generate power for the power consumers. For example, the power generator to be determined needs to generate power for a plurality of power consumers, if the power generator to be determined only generates power for one or a few of the power consumers, the power consumers can meet the requirements, and if the power generator generates power for all the power consumers, the power consumers cannot meet the requirements of the power consumers.
If the power generator to be determined can meet the requirement of the expected power utilization information of the power consumer, an acceptance instruction can be sent out, and if the power generator to be determined can not meet the requirement of the expected power utilization information of the power consumer, a abandon instruction can be sent out. And if the abandoning instruction of the power generator to be determined is received, determining that the power generator to be determined abandons the transaction with the user side, wherein the power generator to be determined is not the target power generator.
