Before transmitting 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 verification with the background server so as to prevent that the execution state of the background server cannot be confirmed due to sudden exit of a small program after the power demand response data is sent out; aiming at each piece of power demand response data sent by the user terminal APP, the background server performs duplicate removal verification according to the unique ID, so that the same piece of power demand response data is prevented from being executed twice, and the same result of the user terminal APP is returned for the same ID; meanwhile, the background server stores each power demand response data into a local database of the background server, and the power demand response data is searched again and used in later audit by the standby user terminal APP.
Referring to fig. 5, the initialization procedure of the second uplink module, which is the uplink module of the user terminal APP, includes the following steps:
(1) After the user terminal APP is started, searching the second database for power demand response data with the local state of 2 (sent to the blockchain);
(2) Inquiring whether the transaction corresponding to the data exists on the blockchain network;
(3) If the corresponding transaction exists, the local state of the transaction is modified to 3 in a second database (successful uplink); if there is no corresponding transaction, its local state is modified to 1 (server returns success) in the second database in order to perform the uplink flow.
Referring to fig. 6, the uplink procedure of the second uplink module, which is the uplink module of the ue APP, is as follows:
(1) The second uplink module queries a local database table of the user terminal APP at regular time to find out power demand response data with a local state of 1 (successful return of the server);
(2) The second uplink module constructs a blockchain transaction for the data;
(3) The second uplink module takes a summary value for the blockchain transaction and records the summary value into a database table field;
(4) The second uplink module transmitting the transaction to the blockchain network;
(5) If the second uplink module receives the uplink success reply returned by the block chain node, modifying the state of the power demand response data in the second database from 1 (successful return of the server) to 3 (successful uplink); if no reply is received, the local state of the power demand response data in the second database is modified from 1 (server returns success) to 2 (sent to the blockchain).
In this embodiment, because the user terminal APP uses the user, the power demand response data generated by the service module is stored in the second database local to the user terminal APP, and then the second uplink module continuously searches the second database for the power demand response data that needs to be uplink for uplink. The present embodiment adopts a design that the service and the blockchain are separated, and the service operation does not depend on the power demand response data existing on the blockchain, but adopts a mode of first occurrence and then uplink. 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 user terminal APP links the operation data (power demand response data), constructs a blockchain transaction for each operation data, and sends transaction details to the blockchain network, wherein the transaction details only need to be linked in one time, and other records related to the operation data take the summary 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 the operation details to the link; the background server is an executor for operating the data uplink, and only needs to abstract details and record the details on the link.
In the subsequent auditing and verifying work, when auditing is performed for certain operation data, the important step is to check whether the abstract value of the transaction details in the uplink record of the user terminal (which is already 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.
The details are all message contents of the transaction sent to the blockchain network, and correspond to the summary value of the transaction.
It should be noted that, when the user terminal is started, the user terminal APP deletes the operation record of successful uplink, and deletes the operation record returned by the background server; for the background server, the requirement of the user terminal APP for later inquiry is met, so that all business operations are recorded and cannot be deleted, and a scheme of permanently reserving 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 does not receive the reply from the background server and an abnormal exit occurs, in this case, if the service operation (that is, 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 service operation, but cannot perform subsequent operations on the service any more. 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 service 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 server", and 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, so that the integrity of each piece of power demand response data sent can be ensured.
When the second uplink module of the user terminal sends a transaction to the blockchain network, if the user terminal does not receive the reply of the blockchain network, the second uplink module of the user terminal can not know whether the operation data (the power demand response data with the status of 'successful return of the server') is already uplink or not after the program is restarted if the user terminal does not exit abnormally, and the service operation data can be possibly repeatedly uplink. In this regard, 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 does not receive the reply of the blockchain node and abnormally exits, after the program is restarted, the user terminal APP executes the initialization flow of the uplink module, so that whether the transaction corresponding to the power demand response data with the state of "server return success" is already uplink or not can be known, the operation data is prevented from being repeatedly uplink, and the accuracy of uplink operation can be ensured.
In this embodiment, the internet of things terminal periodically collects power data through the first service module and stores the power data in the first database, and after setting the state of the power data to "send to server", sends the power data 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 'successful return of the server' to the blockchain network through the first uplink module to perform uplink operation. It should be noted that, the uplink processing flow performed by the first uplink module of the internet of things terminal is basically the same as the uplink processing flow performed by the second uplink module of the user terminal APP.
Specifically, the internet of things terminal regularly collects power data through a first service module and stores the power data in a local first database, the collected power data is added in the first database, the state of the power data is set as 'sending to a server', and then the power data is sent to the server; and the server receives the power data and returns a response message, if the response message returned by the server is successfully received by the Internet of things terminal, 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 errors". The method comprises the steps that an Internet of things terminal searches power data with a state of 'server return success' in a first database through a first uplink module, constructs a blockchain transaction, stores a summary value of the transaction in the first database, sends the transaction to a blockchain network to execute uplink operation, and if the uplink is successful, modifies the state of the power data in the first database into 'uplink success', otherwise, modifies the state of the power data in the first database into 'send to blockchain'; after receiving the power data of the internet of things terminal and returning response information, the server adds the power data into a third database and sets the state of the power data as a 'complete internet of things terminal request', searches the power data with the state of the 'complete internet of things terminal request' in the third database, constructs a blockchain transaction, sends the abstract value of the transaction to the blockchain network, changes the state of the power data in the third database into a 'successful uplink' if the uplink is successful, and changes the state of the power data in the third database into a 'send to blockchain' if the uplink is not successful.
It should be noted that, the initialization process of the first uplink module is executed, and the power data in the first database with the status of "successful uplink" or "error returned by the server" can be located and cleaned.
According to the method, the server determines and distributes the power demand 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 power demand response action according to the received power demand distribution.
The business processing flow of the third business module of the background server is as follows: after the server receives the power data sent by the Internet of things terminal and returns a response message corresponding to the power data to the Internet of things terminal, the power data is stored in a third database of the server, and the state of the power data is set as 'completing the Internet of things terminal request'; 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 'completing the request of the internet of things terminal'.
The uplink processing flow of the third uplink module of the background server is as follows: the server searches the third database for the power data or the power demand response data with the state of 'completing the user terminal request' (with the corresponding state of 0), constructs a blockchain transaction, sends the abstract value of the transaction to the blockchain network, and if the uplink is successful, modifies the state of the power data or the power demand response data in the third database to be 'successful' (with the corresponding state of 2), otherwise, modifies the state of the power data or the power demand response data to be 'sent to the blockchain' (with the corresponding state of 1).
In this embodiment, after the power data of the internet of things terminal or the power demand response data of the user terminal APP is processed, the background server service module adds a new record in 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 of which the uplink is completed, and all the data records are to be reserved in the local database of the background server, that is, the third database.
The data bypass link method suitable for power demand response provided by the embodiment is that before the terminal sends the terminal data to the background server, namely 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 'send to the server', and the state of the terminal data is modified after the response message returned by the server is received, 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 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 a uplink data source and improving the accuracy and the data security of service operation. According to the invention, the terminal only initiates the service request to the background server, and does not directly send the service request to the blockchain, so that the decoupling of the operation of the power service system and the blockchain is realized, the service accuracy of the power system demand response blockchain system is greatly improved, and the timeliness of service response and the user experience in the power demand response scene can be ensured.
As a specific embodiment, in order to verify the practicability and advancement of the data bypass uplink system and method scheme provided by the present invention, the method of the present invention and two conventional schemes are subjected to simulation test, and the test deployment architecture is shown in fig. 7 and 8.
Normal scene test flow, test results are shown in table 3:
1) The background server issues 1000 response demand notices;
2) After receiving the demand announcements, the user terminal APP reports the response quantity and price data to a background server, and after receiving the information reported by all the user terminals APP, the background server sequentially clears the price from low to high, distributes the demand response qualification to the user terminals APP, and finishes the distribution of 1000 response demands.
3) Recording data; the above steps were then repeated 3 times.
TABLE 3 Table 3
Abnormal scene test flow, test results are shown in table 4:
1) The background server issues 1000 response demand notices;
2) After receiving the demand announcement, the user terminal APP reports the response quantity and price data to a background server. At the mobile phone end, the APP process is immediately exited every time the user terminal APP finishes transmitting the request. And after receiving the information reported by all the user terminals APP, the background server sequentially clears the price from low to high, and distributes the demand response qualification to the user terminals APP until 1000 response demands are distributed.
3) Recording data; the above steps were then repeated 3 times.
TABLE 4 Table 4
In the first round of normal scene test, the total number of successful response demands of the user terminals in the three uplink modes is 1000, and the total number of successful response demands is consistent with the total number of the distribution demands of the background service, and no error on demand distribution exists. As can be seen from the results, the traffic accuracy and the uplink accuracy of the mode a are 100%, but the average traffic execution time and the average uplink time are significantly longer than those of the mode B and the mode C. The average service execution time and the average uplink time of the 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 scene test, the total number of successful response demands of the terminals in the mode A and the mode C is 1000, the total number of three groups of demand distribution in the mode B is less than 1000, and omission and errors in service execution exist. Although the mode a still keeps 100% accuracy, the service execution time and the uplink time are greatly slowed down, which seriously affects the use of the user. Mode C still has a faster response time with 100% accuracy guaranteed.
The test results show that the service execution and the data link up-link of the system can still reach 100% accuracy even if the service system continuously exits abnormally by using the data bypass uplink scheme provided by the invention, and the high safety and loose coupling characteristics and the advancement compared with the traditional uplink provided by the invention are verified. On the other hand, the bypass uplink scheme can achieve service execution time of 100ms on average and uplink time of 200ms on average, and timeliness of service response and user experience in a power demand response scene can be guaranteed.
Compared with the existing uplink scheme, the scheme of the invention realizes that the business system keeps independent, each terminal only initiates a request to the background service and does not directly send the request to the blockchain, and if the blockchain network fails or the connection is lost, each terminal and the background service only need to remove the database and the uplink module, the system becomes a traditional business system, and normal operation can be kept. In addition, the scheme solves the existing problems of the proxy uplink mode by allowing the uplink module of each terminal to directly interact with the blockchain, eliminates the potential risk of wrongly acting on the background terminal, and ensures the correctness of service data.
