[0016] Figure 1 This is a block diagram of a power data transmission system according to the present invention. Detailed Implementation
[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0018] refer to Figure 1 A power data transmission system, comprising: Field device modules are used to collect raw data such as voltage and current. Communication terminal module, used to connect field devices to the network; Communication network module, used as a conduit for data transmission; The main station system module is used to receive, process, store, and display all data, supporting various advanced applications.
[0019] The field equipment module includes various sensors, smart meters, and relay protection devices.
[0020] In the communication terminal module, the data transmission unit is the core device, which is used to convert serial port data into IP data packets and transmit them through 4G / 5G and other networks.
[0021] The communication terminal module also includes a remote terminal unit for protocol conversion and data uploading.
[0022] The communication network module includes communication media such as optical fiber, 4G / 5G, and power line carrier.
[0023] The communication network module includes a quantum encryption transmission module. In the quantum encryption transmission module, the dispersed power plant data is first aggregated to the regional control station through a wireless quantum encryption unit, and then transmitted over a long distance to the dispatch center through an optical fiber quantum encryption unit.
[0024] The quantum state carrier of the wireless quantum encryption unit is a single photon or an entangled photon pair. The encoding method is polarization encoding, time phase encoding, and orbital angular momentum encoding. The transmission medium is near-infrared light penetrating the atmosphere. The key generation follows the BB84 / B92 / E91 protocol and is post-processed.
[0025] The fiber optic quantum encryption unit includes: Quantum light source unit, used to generate weakly coherent pulses or entangled photon pairs, including phase randomization and decoy state modulation; Encoding modulators are used to encode key bits into quantum states; Fiber optic channels are used to transmit quantum states; Single-photon detectors are used for the efficient detection of quantum signals; The post-processing system is used for error correction, privacy amplification, and generation of the final security key.
[0026] The quantum encryption transmission module includes a quantum key distribution unit and a quantum true random number unit; The quantum key distribution unit is used to allow the two communicating parties to generate and share a random key that only they know; The quantum true random number unit is used to generate truly unpredictable random numbers by utilizing the intrinsic randomness of quantum processes, ensuring that the key used for encryption is itself an absolutely secure source.
[0027] The quantum state carrier of the wireless quantum encryption unit is based on the quantum no-cloning theorem; eavesdropping will inevitably disturb the quantum state. The encoding method of the wireless quantum encryption unit is rotationally invariant, so the transmitting and receiving ends do not need to be precisely aligned with the reference frame; The wireless quantum encryption unit does not require the laying of optical fibers for transmission, making it flexible in deployment and capable of traversing complex terrains. Key generation for wireless quantum encryption units is information-theoretic secure and resistant to attacks with unlimited computing power.
[0028] Quantum key distribution (QKD) allows communicating parties to generate and share a random key that only they know. Its security stems from a fundamental principle of quantum mechanics: any eavesdropping on a quantum state will inevitably alter the quantum state itself, thus being detected by the communicating parties. This fundamentally eliminates the possibility of the key being copied or stolen during distribution.
[0029] Quantum True Random Numbers (QRNG): Traditional encryption relies on "pseudo-random numbers," which are inherently predictable. Quantum random number generators, however, utilize the intrinsic randomness of quantum processes (such as vacuum fluctuations and photon phase) to generate truly unpredictable random numbers. This ensures that the key used for "one-time pad" encryption is itself an absolutely secure source.
[0030] Fiber optic quantum encryption is currently the most mature and widely used quantum secure communication technology. Simply put, it uses optical fiber as the transmission medium and quantum key distribution (QKD) technology to securely generate and share a key between the communicating parties, and then uses this key to encrypt and transmit business data.
[0031] In simple terms, wireless quantum encryption uses quantum technology to encrypt data in wireless communications. While this sounds similar to traditional encryption, its revolutionary aspect lies in the fact that the quantum key used for encryption is also securely distributed wirelessly. Its security is guaranteed by physical laws, not mathematical complexity. It primarily addresses a core pain point: providing "quantum-level" security for massive numbers of power terminals in remote areas where fiber optic cables cannot reach (such as mountainous hydroelectric power stations).
[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
