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: A water purification module configured to reduce the total organic content of water that flows through a water flow path of a water purification system between an inlet and a first point of use dispenser. The water purification module defines a first recirculation water flow path loop in the water flow path that is in fluid communication with, and forms part of, the water flow path of the water purification system. The water purification module includes a pump, an ultraviolet radiation treatment device, and a tank fluidly connected in the first recirculation water flow path loop such that water that enters the inlet to the water flow path of the water purification system is circulated one or more times through the first recirculation water flow path loop of the water purification module by the pump to generate purified water having a reduced total organic content. The purified water is selectively dispensable from the water purification system at the first point of use dispenser.
