[0002] As the power industry continues to improve its information technology, power plants have generally deployed independent portal application systems to centrally manage user identities, permissions, and business processes. However, because these portal systems are developed by different vendors, their login mechanisms, interface specifications, and security policies vary significantly, making integration difficult.

[0003] At the same time, SIS systems, as a crucial component of power plant operation monitoring, are typically independently deployed applications with their own user authentication and access control systems. Achieving seamless integration with multiple power plant portal systems without modifying the SIS's existing architecture has become a pressing challenge in power informatization.

[0004] Traditional solutions often require custom development of adapters for each portal system or modification of the SIS system code. This not only has high development costs and long cycles, but is also difficult to maintain and cannot meet the needs of rapid deployment and flexible expansion.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0024] A method for rapidly integrating a thermal power plant SIS system with a third-party power plant portal system, characterized by comprising the following steps: S1. The integrated application system directs the integrated login request of the target system to the third-party portal system, and obtains the user login information of the integrated login request according to the first token generated by the portal system for the integrated login request; S2. The integrated application system obtains a second token of the target system according to the user login information; S3. The integrated application system caches the first token and the second token using the encryption key; S4. The integrated application system receives a login instruction from the target system, where the login instruction is generated by the target system after detecting the login key. The corresponding second token in the cache system is queried according to the target system identifier and the encryption key and its validity is verified. After the verification is passed, the target system is logged in.

[0025] Example 1 In this embodiment, the SIS system is used as the target system, the SIS integrated application system is used as the integrated application system, and the power plant portal system is used as the third-party portal system for illustration.

[0026] A method for rapidly integrating a thermal power plant SIS system with a third-party power plant portal system includes the following steps: S1. The SIS integrated application system directs the integrated login request of the SIS system to the power plant portal system. The SIS integrated application system obtains user login information of the integrated login request based on a first token generated by the power plant portal system in response to the integrated login request. The first token is a token generated after the power plant portal system verifies the integrated login request; The SIS integrated application system acts as an intermediary, redirecting the SIS system's integrated login request to the power plant portal system. Upon receiving the request, the SIS integrated application system redirects it to the power plant portal system. Upon receiving the request, the power plant portal system verifies the user's identity. Upon successful verification, it generates a primary token and returns it to the SIS integrated application system within the redirection URL. The SIS integrated application system then uses this primary token to access the user's login details by calling the power plant portal system's API.

[0027] Single sign-on (SSO) is implemented between the SIS and the power plant portal system. Users only need to authenticate in one system to automatically log in to the other, eliminating the need to repeatedly enter their username and password. This significantly improves user experience and login efficiency. The token mechanism also enhances system security, ensuring the authenticity of user identities and the security of data transmission.

[0028] S2. The SIS integrated application system obtains a second token of the SIS system based on the user login information; After receiving the user login information from the power plant portal system, the SIS integrated application system uses this information to call the SIS API to obtain the SIS secondary token. This secondary token is an important credential used by the SIS system for internal user authentication and access control, representing the user's identity and permissions within the SIS system.

[0029] By obtaining a secondary token from the SIS system, the SIS integrated application system can achieve seamless integration with the SIS system without modifying the original SIS system architecture. At the same time, the secondary token ensures the consistency and accuracy of user authentication and access control within the SIS system, improving system security and stability.

[0030] S3. The SIS integrated application system caches the first token and the second token using an encryption key; After obtaining the first and second tokens, the SIS integrated application system encrypts them using an encryption key and caches the encrypted tokens in the distributed cache system. The cache key consists of the system identifier and a randomly generated LoginKey, ensuring the uniqueness and queryability of the cached data.

[0031] By caching tokens, SIS integrated applications can reduce the frequency of token generation and verification operations, thereby improving system response speed and performance. At the same time, using encryption keys to encrypt tokens also ensures the security of cached data and prevents the leakage and abuse of token information.

[0032] S4. The SIS integrated application system receives a login instruction from the SIS system, which is generated after the SIS system detects the login key. According to the SIS system identification and encryption key, the corresponding second token in the cache system is queried and its validity is verified. After the verification is passed, the SIS system is logged in.

[0033] After receiving the SIS login command (generated by the SIS after detecting the login key), the SIS integrated application system queries the cache system for the corresponding second token based on the SIS system identifier and encryption key and verifies its validity. If the verification is successful, the SIS integrated application system completes the SIS system login operation and returns the user information, token, and LoginKey to the page cache for subsequent user access and operation.

[0034] By validating the cached token, the SIS integrated application system enables automated SIS login, eliminating the need for users to re-enter their username and password, improving user experience and login efficiency. Verifying the validity of the token also ensures login security, preventing unauthorized access and manipulation. Furthermore, the caching and verification mechanisms ensure the consistency and accuracy of user data between the SIS and the power plant portal system.

[0035] This method for rapidly integrating a thermal power plant SIS with a third-party power plant portal system uses an intermediate integration application system as a bridge, achieving seamless integration with multiple power plant portal systems without modifying the core SIS logic. Technically, this method leverages key technologies such as token mechanisms, distributed caching, and cryptographic verification to ensure secure and efficient user authentication.

[0036] During the integration process, the power plant portal system first verifies the user's identity and generates a token. The SIS integrated application system then uses this token to obtain user details and further generate a token for the SIS system. These two tokens are encrypted and cached in the distributed system for subsequent login verification and session management. When a user accesses the SIS system, the system verifies the user's identity by querying the token information in the cache, thereby achieving automated login. In addition, this method also supports a unified logout function, ensuring that the user's login status can be updated synchronously across different systems. This not only greatly reduces the complexity and cost of system integration, avoids the tedious process of customizing and developing adapters for each portal system, but also improves the system's flexibility and scalability. At the same time, through the token mechanism and encryption verification, the security of user authentication and the confidentiality of data transmission are ensured, providing users with a more convenient and secure login experience. This technical solution not only achieves rapid integration of the SIS system with a third-party power plant portal system, but also ensures the security, flexibility, and scalability of the system.

[0037] In some embodiments, the SIS integrated application system directs the integrated login request of the SIS system to the power plant portal system, and the SIS integrated application system obtains user login information of the integrated login request based on a first token generated by the power plant portal system in response to the integrated login request, including: The user starts the SIS system through integrated login. After receiving the integrated login request, the SIS integrated application system directs the integrated login request to the login page of the power plant portal system according to the configuration information. After the power plant portal system verifies the user's identity information, it generates a first token and jumps to the designated callback address of the SIS integrated application system.

[0038] In some embodiments, the SIS integrated application system obtains the second token of the SIS system according to the user login information, including: The SIS integrated application system obtains user login information from the power plant portal system according to the first token; Configure the user login information into the SIS system, and generate a second token of the SIS system according to the API of the SIS system. The second token is the token information of the SIS system.

[0039] In some embodiments, the SIS integrated application system caches the first token and the second token using an encryption key; The SIS integrated application system randomly generates a universal unique identifier (UUID) as the login key (LoginKey); Generate a cache key based on the login key and cache the first token and the second token in the distributed cache system respectively; The cache key of the first token consists of the power plant ID plus the login key LoginKey; The cache key of the second token consists of the SIS system identifier plus the login key LoginKey.

[0040] The user's browser is redirected to the homepage of the SIS system. The SIS integrated application system redirects the integrated login request of the SIS system to the power plant portal system through the constructed URL and appending the login key LoginKey to the URL.

[0041] In some embodiments, the SIS integrated application system receives a login instruction from the SIS system, where the login instruction is an instruction generated by the SIS system after detecting a login key; The SIS system homepage detects the login key LoginKey, starts the login instruction and connects to the SIS system integrated login interface.

[0042] In some embodiments, the corresponding second token in the cache system is queried based on the SIS system identifier and the encryption key and its validity is verified. After the verification is passed, the SIS system is logged in.

[0043] After the SIS system integration system receives the login instruction, the SIS system integration system queries the first token of the corresponding SIS system in the cache system according to the buffer key and verifies the validity of the first token. After the validity verification is passed, the user logs in to the SIS system.

[0044] When the first token is not found or the first token verification fails, the system is redirected to the SIS integrated application system.

[0045] In some embodiments, when a user logs out of the SIS system, the user obtains a login key, deletes relevant information in the browser cache, and logs out of the SIS system.

[0046] Example 1 See Figure 1 and 2 A method for quickly integrating a thermal power plant SIS system with a third-party power plant portal system includes the following steps: Step 1: Set the login mode flag in the SIS system to determine whether integrated login is enabled. If integrated login is enabled, jump to the login interface of the SIS integrated application system; When necessary, it is necessary to configure the SIS system login identifier and the login interface address and logout interface address of the SIS integrated application system in the SIS system.

[0047] Step 2: The SIS integrated application system redirects the user's request to the login page of the corresponding power plant portal system based on pre-configured information; It should be noted that the SIS integrated application system needs to pre-configure the basic parameter information and corresponding interface addresses of the SIS system and each power plant portal system in order to realize dynamic routing and interface calling.

[0048] Step 3: After the user completes identity authentication in the power plant portal system, the power plant portal system generates a token and carries this token to jump back to the designated callback address of the SIS integrated application system; The token generated by the power plant portal system after completing user identity authentication should contain the user identity and validity period information, and be transmitted to the SIS integrated application system through the HTTPS secure channel.

[0049] Step 4: The SIS integrated application system uses the obtained token information to call the API of the power plant portal system to obtain detailed information of the logged-in user; When the SIS integrated application system calls the power plant portal system API interface to obtain user information, it must carry a valid token for identity authentication to ensure the security and legitimacy of the interface call.

[0050] Step 5: After the SIS integrated application system obtains the user's login information, it first updates the user information to the SIS system database, and then calls the SIS system API to generate the SIS system token information; Whether to synchronize the acquired user basic information to the SIS system database is a configurable option. At the same time, when calling the SIS system's interface to generate a token, an encryption verification mechanism is added to generate encryption parameters for the login account information according to the encryption rules agreed upon by both parties. The token can only be generated after the SIS system verification is passed.

[0051] Step 6: The SIS integrated application system randomly generates a universally unique identifier (UUID) as the login key. It then caches the power plant portal system token and the SIS system token in the distributed cache system.

[0052] Among them, the cache key Key of the power plant portal system Token is composed of the power plant identifier plus the login key LoginKey, while the cache key Key of the SIS system Token is composed of the SIS system identifier plus the login key LoginKey.

[0053] Finally, the browser is redirected to the SIS system homepage with the login key LoginKey appended to the URL; When SIS system tokens and power plant portal system tokens are cached in the distributed cache system, a reasonable expiration time must be set to ensure data security and consistency.

[0054] Step 7: After the SIS homepage detects the presence of the LoginKey, it calls the SIS system integration login interface. Based on the SIS system ID and the LoginKey, the SIS system integration login interface queries the cache system for a corresponding Token and verifies its validity. If so, the login is successful, and the user information, Token, and LoginKey are returned to the page and cached in the browser cache, allowing the page data to load. If not, or if the Token is invalid, the page is redirected to the SIS integrated application system's login interface.

[0055] Before loading the SIS system homepage, it should first determine whether key data such as LoginKey, user information and Token already exist in the browser cache; if so, directly modify the browser routing address and load the system data; if not, re-call the login interface to complete the login process.

[0056] Step 8: When the user chooses to log out, first obtain the LoginKey from the browser cache, then delete the relevant information in the browser cache, and call the logout interface of the SIS integrated application system; Before executing the logout operation, you must first obtain the LoginKey data from the browser cache, then clear the browser's local cache, and finally call the logout interface of the SIS integrated application system.

[0057] Step 9: The SIS integrated application system obtains the SIS system token information in the cache system based on the SIS system ID plus the LoginKey, and then calls the SIS system's integrated logout interface with the token information; Before calling the SIS system logout interface, the SIS integrated application system must accurately obtain the Token information based on the Key value of the SIS system identifier and the LoginKey, and carry the Token to complete the SIS system logout operation.

[0058] Step 10: When the SIS system exits successfully, the SIS integrated application system deletes the SIS system token information in the distributed cache system based on the SIS ID plus the LoginKey, then obtains the power plant portal system token information in the cache system based on the power plant ID plus the LoginKey, and then calls the exit interface of the power plant portal system with the token information; Before calling the power plant portal system logout interface, the SIS integrated application system must first obtain the power plant portal system's Token information based on the key value of the power plant ID and the LoginKey combination, and carry the Token to complete the portal system logout operation.

[0059] Step 11: Once the power plant portal system successfully processes the logout request, the SIS application deletes the power plant portal system token from the distributed cache using the power plant ID and the LoginKey. Finally, the entire process redirects back to the SIS system integration login page.

[0060] When the power plant portal system completes the logout operation, the SIS integrated application system deletes the corresponding power plant portal system Token information from the distributed cache system based on the key value of the power plant ID and LoginKey, and redirects the user browser to the integrated login page of the SIS system to complete the complete unified logout process.

[0061] The present invention provides a method for rapidly integrating a thermal power plant SIS system with a third-party power plant portal system. Without modifying the core logic of the SIS system, the method can achieve compatible access to various portal systems of third-party power plants through an intermediate integrated application system, thereby realizing functions such as single sign-on, user information synchronization, token management, and unified logout.
