    Abstract: A switch monitoring method and a switch monitoring system, a railway line management method and a railway line management system are provided. Electric signal of a switch motor during pulling of the switch can effectively reflect status of the switch, when the switch is in a stable state, electric signal of its motor is very steady during pulling of a switch of the switch; however, when the switch is in an unstable state, there will be different degrees of fluctuation in electric signal of its motor during pulling of the switch. Thus, the invention may be used to identify state of a switch by monitoring electric signal of a switch motor (201,203,205), and further take different measures based on different states of the switch (401,403,405). With these measures, accidents due to switch failure may be effectively reduced, and train delay time may also be reduced through proper line management.

    Abstract: The present invention relates to multi-user analytical system and corresponding device and method. The device includes an interception module configured to intercept a user's request for a first core object, wherein the first core object belongs to core object; a transformation module configured to create, in response to the request being a creation request, the first core object specific to the user; a mapping module configured to interpret, in response to the request being a non-creation request, the request as a request for the first core object specific to the user. The present invention also includes an isolation method for the multi-user analytical system. The technical solutions provided in the present invention can effectively enable multiple users to share physical resources in the analytical system, and the users are isolated from each other in a substantially transparent way.

    Abstract: The invention relates to compressed data transmission in wireless data communication. Disclosed are methods and apparatuses for transporting residue of vehicle position data via a wireless network. A disclosed method for transporting residue of vehicle position data via a wireless network, includes the steps of: receiving data for updating residue encoding schema from a monitoring server; constructing a residue encoding schema based on the data, thereby producing a constructed residue encoding schema; and storing the constructed residue encoding schema such that the constructed residue encoding schema will become the current residue encoding schema; where: the constructed residue encoding schema is constructed such that each residue of the constructed residue encoding schema corresponds to a code; and the constructed residue encoding schema is constructed such that a residue having a relatively high probability of occurrence corresponds to a code of relatively short length.
