  • Publication number: 20230391386
    Abstract: A safety information supervision apparatus applied to a high-speed rail signaling system includes a communication processor, a Radio Block Center (RBC) interface machine, a Centralized Traffic Control (CTC) interface machine, a supervision and analysis server, an analysis terminal, and a storage device, where the communication processor and the RBC interface machine are communicatively connected to the supervision and analysis server through a monitoring network. The CTC interface machine is communicatively connected to the CTC system of a station and the supervision and analysis server, so as to obtain train information in the CTC system and to transmit an analysis result of the supervision and analysis server to the CTC system through the CTC interface machine. Multi-source data fusion analysis is used to perform filtering and validity analysis on basic data, thereby reducing false alarms.

  • Patent number: 11809269
    Abstract: The present invention relates to a fault diagnosis and intelligent warning method for monitoring a system device, including the following steps: step 1. establishing independent alarm analysis logic and independent recovery analysis logic based on a fault model of each alarm; step 2. controlling the alarm logic and the recovery logic to be mutually exclusively executed; the step 3. performing delay processing on an alarm event and a recovery event; and step 4. establishing a cascading relationship between alarm events generated after the delay processing: establishing an alarm cascading group based on a relationship between different alarm events, automatically determining, by using generation of an alarm event as a triggering condition, whether alarms in a same cascading group simultaneously exist within a time, and generating association information between alarm events.

  • Patent number: 9109003
    Abstract: The present invention provides an extraction method for the leaves of Ilex kudingcha C. J. Tseng, and the total saponins from I. kudingcha leaves extracted by using this method, and use of the total saponins in preparing a drug for reducing cholesterol and blood lipids and anti-atherosclerosis. The extraction method comprises the following steps: subjecting I. kudingcha leaves to refluxing extraction with ethanol aqueous solution to obtain an extracted solution; filtering the extracted solution and removing ethanol, and then separating and purifying the solution using a macroporous resin column.
