Abstract: The invention discloses a blockchain-based intrusion detection system for railway signal, which is built on a blockchain's distributed chain structure, without a central, trusted control center. This design mitigates the vulnerabilities associated with centralized intrusion detection centers. Additionally, by utilizing a blockchain-based distributed structure, it also eliminates the risk of a single point of failure for the intrusion detection center. Moreover, the data within the blockchain-based intrusion detection system is highly resistant to malicious tampering. This is achieved by leveraging the consensus mechanism inherent in the blockchain, which can achieve consensus among intrusion detection nodes. The current invention solves the internal evil attacks and avoid the inability to reach consensus between nodes due to internal evil, thereby affecting the intrusion detection performance; at the same time, the intrusion detection model can resist external network attacks.

Abstract: The present invention provides a method for integrated utilization of a calcium chloride solution and CO2. In this method, with the calcium chloride solution and the CO2 being taken as raw materials, a water-soluble amine is added as an auxiliary agent to promote the occurrence of a mineralization reaction. As a result of crystallization following the reaction, calcium carbonate and a solution of a hydrochloride of the water-soluble amine are obtained. After the reaction is completed, the water-soluble amine is regenerated by subjecting a liquid phase resulting from separation to bipolar membrane electrodialysis, and dilute hydrochloric acid is obtained as a by-product at the same time. The method provides a novel perspective and approach to integrated utilization of calcium chloride-containing liquid waste and flue gas CO2. The water-soluble amine allows excellent mineralization, and the bipolar membrane electrodialysis enables excellent regeneration of the amine.
