Abstract: The present invention relates to a sample collection and testing device for analyzing and testing an analyte in a liquid sample. The sample collection device includes a collection inner cavity and a collection outer cavity. The collection inner cavity is disposed inside the collection outer cavity. The collection inner cavity communicates with the collection outer cavity via through holes at a bottom portion of the collection inner cavity. The collection inner cavity is movable between a first position and a second position relative to the collection outer cavity. When the collection inner cavity is at the first position, the liquid sample is collected into the collection outer cavity. When the collection inner cavity is at the second position, the liquid sample is discharged out of the collection outer cavity.

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.
