Description

TECHNICAL FIELD

[0001] The present application belongs to the field of power plant fuel management, and relates to a power plant fuel data verification method and system. BACKGROUND

[0002] The power plant fuel management system is a digital platform for the power plant and its affiliated group to check the weight and quality of fuel, and the purpose is to strengthen the monitoring of the fuel circulation link, realize the purpose of improving efficiency, reducing cost and safe production. Fuel is the core of the operation process of the power plant, and its procurement cost usually accounts for more than 70% of the operation cost of the power plant. Ensuring high-quality and low-price fuel is the basis for ensuring stable and efficient operation of the power plant boiler and an important way to save cost of the power plant. Due to the special requirements of the business, the fuel management system has high requirements for the security and confidentiality of data. Usually, the fuel management system will encrypt the data generated in the process of checking the weight and quality of fuel to prevent the data from being tampered with by the fuel supplier and the power plant staff, and thus provide safe and private original data for fuel settlement.

[0003] The traditional way of managing the fuel system by manpower has many problems. For example, during the process of entering the plant to check the weight and quality, there are work errors, non-standard operation, and even illegal and criminal behaviors of colluding with internal and external personnel to maliciously tamper with relevant data. Therefore, the informatization of the power plant fuel system is imperative. Through informatization means, the changes of key data at each level are tracked in time, and the relevant decision-making management personnel are fed back in time, so as to realize safe and reliable management of the fuel system.

[0004] However, at present, in order to ensure safe and reliable operation, the power plant generally implements internal and external network isolation and establishes a landing database to store information. The power plant staff can realize human intervention on the data by modifying the local database and erasing the database log file. In addition, the power plant staff can collude with the group side personnel to obtain the data encryption algorithm to tamper with the transmission message or pretend to be the power plant side to send false data to the group side. SUMMARY

[0017] Optionally, the power plant fuel data is sent to the group side server and the third party server in real time through a laboratory data acquisition system, a sample weighing system, and a full-automatic sample preparation system of the power plant.

[0018] Optionally, after the power plant fuel data verification passes, the group side server generates data approval information and sends it to the power plant; after the power plant fuel data verification fails, the group side server generates data re-collection information and sends it to the power plant.

[0020] The group side data acquisition module and the third party data acquisition module are both used to acquire power plant fuel data in real time;

[0031] It should be noted that the terms "first", "second" and the like in the specification and claims of the application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not necessarily limit to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0032] The application will be further described in detail below with reference to the drawings:

[0033] In an embodiment of the present application, a power plant fuel data verification method is provided, which is applied to a power plant fuel data verification system, and the power plant fuel data verification system comprises a group side server and a third party server connected with each other. The power plant fuel data verification method comprises the following steps: the group side server and the third party server acquire power plant fuel data in real time; the third party server randomly selects a hash function from a preset first hash function library to obtain a target hash function, performs hash operation on the power plant fuel data through the target hash function, obtains a first hash value, and sends the first hash value to the group side server; the group side server traverses all hash functions in a preset second hash function library, sequentially performs hash operation on the power plant fuel data to obtain a plurality of second hash values, and compares whether there is a second hash value identical to the first hash value in the plurality of second hash values; when there is a second hash value identical to the first hash value in the plurality of second hash values, the power plant fuel data verification passes; otherwise, the power plant fuel data verification fails; wherein the hash functions in the first hash function library and the second hash function library are identical.

[0034] In a possible implementation, when the first hash value is sent to the group side server, the first hash value is encrypted by a preset private key to obtain ciphertext and send the ciphertext to the group side server; the group side server decrypts the ciphertext by a preset public key, and when the decryption operation is successful, the first hash value is obtained; when the decryption operation fails, the group side server generates information of re-sending the ciphertext to the third party server.

[0035] In a possible implementation, the preset private key and the preset public key are generated by using an elliptic curve encryption algorithm (EEC).

[0036] In a possible implementation, the first hash function library and the second hash function library each comprise at least two of an MD4 function, an MD5 function, an SHA-1 function, an SHA-224 function, an SHA-256 function, an SHA-384 function, an SHA-512 function, an SM3 function, and a Keccak function.

[0037] In a possible implementation, the power plant fuel data comprises one or more of coal total moisture data, air dry basis moisture data, ash content data, sulfur content data, volatile matter data, bomb calorific value data, hydrogen value data, Hardgrove grindability index data, sample gram weight data, assay time data, and assayer information data.

[0038] In a possible implementation, after the power plant fuel data verification passes, the group side server generates data approval information and sends the data approval information to the power plant; after the power plant fuel data verification fails, the group side server generates data re-collection information and sends the data re-collection information to the power plant.

[0039] In a possible implementation, the power plant fuel data verification method specifically implements the following steps:

[0040] 1) The power plant side collects power plant fuel data and simultaneously sends the power plant fuel data to a third-party server and a group side server.

[0041] 2) The third-party server receives the power plant fuel data from the power plant side, randomly selects a hash function from a first hash function library to perform hash operation on the data to generate a first hash value, encrypts the first hash value using a private key to generate a ciphertext, and sends the ciphertext to the group side server.

[0042] 3) The group side server receives the power plant fuel data from the power plant side, uses all hash functions in a second hash function library to perform hash operation on the power plant fuel data to obtain a hash value set of second hash values.

[0043] 4) The group side server receives the ciphertext from the third-party server, decrypts the ciphertext using a public key to obtain the first hash value, compares the first hash value with the hash value set obtained in step 3), if the first hash value is the same as a second hash value in the hash value set, it is considered that the power plant fuel data collected by the power plant side is approved, otherwise, the power plant fuel data is rejected, and information is sent to the power plant side to indicate that it is re-collected.

[0044] In summary, the power plant fuel data verification method of the present application can effectively prevent the power plant fuel data collected from being artificially intervened after the power plant fuel data is collected. At the same time, by introducing a third-party server to encrypt the power plant fuel data using a randomly selected encryption algorithm, it can effectively prevent the power plant personnel from obtaining the encryption algorithm and forging the power plant fuel data, and can ensure that the power plant fuel data is not landed, reduce human intervention, and meet the real-time, accuracy and security requirements of the power plant for the power plant fuel data.

[0045] Referring to Figure 1 , the following describes the power plant fuel data verification method of the present application in a typical application scenario, which includes a power plant side, a third-party institution and a group side. Among them, the power plant side sets a device layer, a data collection layer and a local server, the third-party institution sets a third-party server, and the group side sets a group side server. Among them, the device layer can include a total water analyzer, a calorimeter, a sulfur analyzer, a high-temperature furnace, an electronic balance, an elemental analyzer, etc. The data collection layer can include a laboratory data collection system suitable for the device layer, a sample weighing system and a full-automatic sample preparation system, etc.

[0046] The power plant fuel data of the power plant side is sent to the third party server and the group side after passing through the equipment layer and the data collection layer in turn, and is saved in the landing database of the local server. Specifically, at the power plant side, the equipment layer is connected to the power plant intranet, and the installation and debugging of the data collection layer are completed on the related terminal equipment. The corresponding operation of the fuel is completed in the equipment layer, and the data generated in the equipment layer is automatically read and processed through the data collection layer. The data is automatically sent by the data collection layer, and is connected to the third party server and the group side server through the firewall and the gate to wait for subsequent processing. The other way is to save in the landing database of the local server. At this time, the state information of the data in the landing database is "unconfirmed".

[0047] After the third party server receives the data transmitted by the power plant side, a hash function is randomly selected from the first hash function library, a hash operation is performed on the power plant fuel data transmitted by the power plant, and a first hash value is obtained. Then, the hash value is encrypted by using the ECC private key to generate a ciphertext. Finally, the ciphertext is sent to the group side server.

[0048] The group side server receives the data from the power plant side and the ciphertext from the third party server. The group side server decrypts the received ciphertext by using the ECC public key agreed with the third party server in advance to generate a first hash value. If the ECC public key decryption is successful, it can be confirmed that the received ciphertext comes from the third party server, and the third party server is sent information to confirm that the ciphertext reception is successful; otherwise, it is considered that the ciphertext comes from an illegal user and is not received, and the third party server is requested to send the ciphertext again. At the same time, the group side server uses the second hash function library agreed with the third party server in advance to perform a hash operation on the received power plant fuel data one by one to obtain a hash value set composed of a plurality of second hash values. The first hash value obtained by decryption is compared with the hash value set. If the same second hash value as the first hash value obtained by decryption can be found in the hash value set, it is considered that the power plant fuel data transmitted by the power plant side is reliable, and the data approval information is sent to the power plant side, and the corresponding data state in the local database of the power plant side is modified to "confirmed"; otherwise, the data re-collection information is sent to the power plant side.
