(2) The user terminal APP sends power demand response data to the background server side;
(3) The background server receives the power demand response data and replies response information corresponding to the power demand response data;
(4) If the user terminal APP receives the response message, finding the power demand response data record sent in the step (1), and changing the local state of the power demand response data record into 1 (the server returns success); otherwise, the status of the power demand response data is modified to 4 (server returns an error).
In this embodiment, each power demand response data sent by the user terminal APP is to achieve a unique and queryable target, and each power demand response data of the user terminal APP generates a unique ID. Before sending a specific power demand response data to the background server, the user terminal APP needs to store the power demand response data into a local database of the user terminal for later checking with the background server, so as to prevent that the execution state of the background server cannot be confirmed due to sudden quitting of a small program after the power demand response data is sent out; for each power demand response data sent by the user terminal APP, the background server performs deduplication verification according to the unique ID, prevents the same power demand response data from being executed twice, and returns the same result of the user terminal APP to the same ID; meanwhile, the background server stores each power demand response data into a local database of the background server for further inquiry and post-audit use of the user terminal APP.
Referring to fig. 5, the initialization procedure of the uplink module of the ue APP, i.e. the second uplink module, includes the following steps:
(1) After the user terminal APP is started, searching for power demand response data with a local state of 2 (sent to a block chain) in a second database;
(2) Inquiring whether a transaction corresponding to the data exists on the block chain network;
(3) If the corresponding transaction exists, the local state of the transaction is modified to 3 (uplink is successful) in the second database; if there is no corresponding transaction, the local status is modified to 1 in the second database (the server returns success) so as to execute the uplink process.
Referring to fig. 6, the uplink procedure of the uplink module of the ue APP, i.e. the second uplink module, includes the following steps:
(1) The second uplink module regularly inquires a local database table of the user terminal APP and finds out power demand response data with a local state of 1 (the server returns success);
(2) The second uplink module constructs block chain transaction aiming at the data;
(3) The second uplink module takes an abstract value aiming at the block chain transaction and records the abstract value into a database table field;
(4) The second uplink module sends the transaction to the blockchain network;
(5) If the second uplink module receives an uplink success reply returned by the block link node, the state of the power demand response data in the second database is changed from 1 (successful return of the server) to 3 (successful uplink); if the reply is not received, the local state of the power demand response data in the second database is changed from 1 (server return success) to 2 (sending to the blockchain).
In this embodiment, the power demand response data generated by the service module due to the use of the user terminal APP is first stored in the local second database of the user terminal APP, and then the second uplink module continuously searches for the power demand response data to be uplink-linked in the second database to perform uplink. The present embodiment adopts a design of separating the service from the blockchain, and the service operation does not depend on the power demand response data already existing on the blockchain, but adopts a first-generation uplink-last mode. In order to ensure the correctness of the uplink data source, the user terminal APP and the background server must respectively perform uplink recording on the same power demand response data, so as to prevent any party from modifying the data of the other party and then uplink the modified data.
The user terminal APP links the operation data (power demand response data) to the chain, a blockchain transaction is constructed for each operation data, the transaction details are sent to a blockchain network, only one link is needed for the transaction details, and other records related to the operation data take the abstract value of the details as a check value. The user terminal APP is an initiator for operating the data uplink and is responsible for sending operation details to the chain; the background server is an executor for operating the data uplink, and only needs to summarize the details and then record the details on the chain.
In the future auditing and verifying work, when a certain operation data is verified, the important step is to check whether the abstract value of the transaction details in the uplink record of the user terminal (which is stored in the second database of the user terminal) is the same as the abstract value of the transaction uplink of the background server: HASH (data type, additional parameters, return value of server) = = check digest value.
It should be noted that the details are the entire message content of the transaction sent to the blockchain network, and correspond to the "digest value" of the transaction.
It should be noted that, when the user terminal starts, the user terminal APP deletes the operation record that the uplink is successful, and deletes the operation record that the background server returns an error; for the background server, as the requirement of later-stage query of the user terminal APP is met, all business operations are recorded and cannot be deleted, and a scheme of permanently retaining operation data and periodically performing cold standby storage is adopted.
In this embodiment, when the user terminal APP sends the blockchain transaction to the blockchain network, the digest value of the transaction is stored in the second database. It should be noted that the power demand response data with the local state of 1 in the second database indicates that the data is service operation data that needs to be uploaded to the blockchain network, and 1 blockchain transaction is constructed for each piece of power demand response data that needs to be uploaded to the blockchain network.
When the user terminal APP sends the power demand response data to the background server, if the user terminal APP abnormally exits when not receiving a reply from the background server, if the business operation (i.e. the sent power demand response data) is not recorded in advance, after the program is restarted, the user terminal APP can check the execution result of the business operation, but cannot perform subsequent operation on the business. Therefore, the invention adopts the mode of recording operation in advance and changing the local state after receiving the reply of the background server to ensure the integrity of the business operation. In this embodiment, before sending the power demand response data to the background server, the user terminal APP sets the state of the power demand response data to "send to the server", modifies the state of the power demand response data to "server return success" or "server return error" according to whether a response message returned by the server is received, and can ensure the integrity of each piece of sent power demand response data.
When the second uplink module of the ue sends a transaction to the blockchain network, if the ue does not receive a reply from the blockchain network, the ue exits abnormally, and if the transaction is not marked in advance, after the procedure is restarted, the second uplink module of the ue cannot know whether the operation data (the power demand response data in the state of "server return success") has been uplink, and may repeatedly uplink the service operation data. In contrast, the present invention adopts a method of recording the abstract value of the transaction corresponding to the operation data in advance and changing the local state after receiving the reply of the blockchain node to ensure the correctness of the uplink operation. If the user terminal APP is abnormally quitted when the user terminal APP does not receive the reply of the block chain node, after the program is restarted, the user terminal APP executes the initialization process of the uplink module, whether the transaction corresponding to the power demand response data with the state of 'server return success' is uplink or not can be known, repeated uplink of operation data is avoided, and the correctness of uplink operation can be ensured.
In the embodiment, the internet of things terminal regularly acquires power data through the first service module and stores the power data in the first database, and after the state of the power data is set to be 'sent to the server', the power data is sent to the server so that the server can determine the power demand, and perform power demand distribution and settlement; and the Internet of things terminal sends the power data with the state of 'server return success' to the block chain network through the first uplink module to carry out uplink operation. It should be noted that the uplink processing flow performed by the first uplink module of the internet of things terminal is substantially the same as the uplink processing flow performed by the second uplink module of the user terminal APP.
Specifically, the internet of things terminal acquires power data at regular time through a first service module and stores the power data in a local first database, adds the acquired power data in the first database, sets the state of the power data as 'sending to a server', and then sends the power data to the server; the server receives the power data and returns a response message, if the internet of things terminal successfully receives the response message returned by the server, the state of the power data is modified to be 'the server returns successfully', otherwise, the state of the power data is modified to be 'the server returns error'. The Internet of things terminal searches for power data with a state of 'server return success' in a first database through a first uplink module and constructs a block chain transaction, stores an abstract value of the transaction in the first database, sends the transaction to a block chain network to execute uplink operation, modifies the state of the power data in the first database into 'uplink success' if uplink is successful, and modifies the state of the power data in the first database into 'sending to a block chain' if uplink is not successful; after receiving the electric power data of the internet of things terminal and returning response information, the server adds the electric power data into a third database and sets the state of the electric power data into 'request for completing the internet of things terminal', searches the electric power data with the state of 'request for completing the internet of things terminal' in the third database and constructs block chain transaction, sends an abstract value of the transaction to a block chain network, if the uplink is successful, the state of the electric power data in the third database is modified into 'successful uplink', otherwise, the state of the electric power data in the third database is modified into 'sending the electric power data to the block chain'.
It should be noted that, by executing the initialization process of the first uplink module, the power data in the first database in the state of "successful uplink" or "server return error" can be located and cleaned.
In the embodiment, the power data of the internet of things terminal and the power demand response data of the user terminal are sent to the server and uplink operation is executed, the server determines and issues the power demand according to the power data sent by the internet of things terminal, power demand distribution is carried out according to the power demand and the power demand response data of the user terminal, the power demand distribution is sent to the corresponding user terminal, and the user terminal controls the internet of things terminal to execute the power demand response action according to the received power demand distribution.
The service processing flow of the third service module of the background server is as follows: after the server receives the electric power data sent by the Internet of things terminal and returns a response message corresponding to the electric power data to the Internet of things terminal, the electric power data is stored in a third database of the server and the state of the electric power data is set to be 'the request of the Internet of things terminal is completed'; or after receiving the power demand response data sent by the user terminal and returning a response message corresponding to the power demand response data to the user terminal, storing the power demand response data in a third database of the server and setting the state of the power demand response data as 'the request of the internet of things terminal is completed'.
The uplink processing flow of the third uplink module of the background server is as follows: the server searches the power data or the power demand response data with the state of 'finishing the user terminal request' (corresponding to the state of 0) in the third database and constructs a blockchain transaction, a summary value of the transaction is sent to a blockchain network, if the uplink is successful, the state of the power data or the power demand response data in the third database is modified to 'uplink is successful' (corresponding to the state of 2), otherwise, the state of the power data or the power demand response data is modified to 'sending to the blockchain' (corresponding to the state of 1).
In this embodiment, after the background server service module processes the power data of the internet of things terminal or the power demand response data of the user terminal APP, a new record is added to the local third database table, which is different from the user terminal APP and the internet of things terminal in that the background server does not have a link of deleting the data record that the uplink is completed, and all the data records are reserved in the local database of the background server, that is, the third database.
Before the terminal sends the terminal data to the background server, that is, before the user terminal sends the power demand response data and the internet of things terminal sends the power data to the server, the terminal data is stored in the terminal database and the state of the terminal data is set as "sent to the server", and after a response message returned by the server is received, the state of the terminal data is modified, so that the integrity of service operation can be ensured; the terminal and the background server respectively carry out uplink recording on the same terminal data, namely the service operation data, so as to prevent any party from modifying the data of the other party and then carrying out uplink, thereby ensuring the correctness of an uplink data source and improving the correctness of service operation and data safety. The terminal only initiates the service request to the background server, and does not directly send the service request to the block chain, so that the decoupling of the operation of the power service system and the block chain is realized, the service accuracy of the power system demand response block chain system is greatly improved, and the timeliness of the service response and the user experience in the power demand response scene can be ensured.
As a specific example, to verify the practicability and the advancement of the data bypass uplink system and method proposed by the present invention, simulation tests were performed on the method of the present invention and two conventional schemes, and the test deployment architecture is shown in fig. 7 and 8.
The test results of the normal scenario test procedure are shown in table 3:
1) The background server issues 1000 response demand announcements;
2) After receiving the demand bulletin, the user terminal APP reports response quantity and price data to the background server, and after receiving information reported by all the user terminal APPs, the background server orderly clears the information according to the price from low to high, and distributes the demand response qualification to the user terminal APP until 1000 response demands are distributed.
3) Recording data; the above steps were then repeated 3 times.
TABLE 3
Figure BDA0003795517050000171
The test result of the abnormal scenario test flow is shown in table 4:
1) The background server issues 1000 response demand announcements;
2) And after receiving the demand announcement, the user terminal APP reports the response quantity and price data to the background server. And at the mobile phone end, the user terminal APP immediately exits the APP process after the request is sent. And after receiving the information reported by all the user terminals APP, the background server sequentially clears the information according to the price from low to high, and allocates the demand response qualification to the user terminals APP until the 1000 response demands are allocated.
3) Recording data; the above steps were then repeated 3 times.
TABLE 4
Figure BDA0003795517050000181
In the first round of normal scenario test, the total number of successful response requirements of the user terminals in the three uplink modes is 1000, which is consistent with the total number of the background service release requirements, and there is no error in requirement allocation. As can be seen from the results, the service accuracy and uplink accuracy of mode a are 100%, but the average service execution time and average uplink time are significantly longer than those of mode B and mode C. The average service execution time and the average uplink time of mode B are faster, but the uplink accuracy is not 100%. Mode C has 100% accuracy and fast response time.
In the second round of abnormal scenario test, the total number of the terminal successful response requirements of the mode a and the mode C is 1000, while the total number of the three groups of requirement allocations of the mode B is not 1000, and there are omissions and errors in service execution. Although the mode a still maintains 100% accuracy, the service execution time and uplink time are greatly slowed down, which seriously affects the user usage. The mode C still has faster response time on the premise of ensuring 100% correctness.
The above test results show that, by using the data bypass uplink scheme provided by the present invention, even under the condition that the service system is continuously abnormally exited, the service execution and data uplink links of the system still can achieve 100% accuracy, and the high security and loose coupling characteristics provided by the present invention and the advancement compared with the traditional uplink are verified. On the other hand, the bypass uplink scheme can achieve the average service execution time of 100ms and the average uplink time of 200ms, and can ensure the timeliness of service response and user experience under the power demand response scene.
Compared with the existing uplink scheme, the scheme of the invention realizes that the service system is kept independent, each terminal only initiates a request to the background service and does not directly send the request to the block chain, and if the block chain network fails or the connection is lost, the system becomes a traditional service system only by removing the database and the uplink module from each terminal and the background service, and can keep normal operation. In addition, the scheme allows the uplink module of each terminal to directly interact with the block chain, so that the problems of the proxy uplink mode are solved, the potential risk of doing malicious work at the background end is eliminated, and the correctness of the service data is ensured.
