Method for clustering wireless channel mpcs based on a kpd doctrine

A kernel-power-density based method for wireless channel multipath components (mpcs) clustering. Signals get to the receiver from a transmitter via multipath propagation. ... Beijing Jiaotong University

A 6dof error laser simultaneous measurement system with a single polarization maintaining fiber coupling and transmitting the dual-frequency laser

A six degree of freedom laser simultaneous measurement system, wherein a laser emitting unit is separated from a fixed sensor head; the laser emitting unit is connected with the fixed sensor head by a single polarization maintaining fiber; a moving unit comprising the reflector and the beam splitter is mounted on the linear guide; utilizing of the single polarization maintaining fiber, which connects the laser emitting unit with the fixed sensor head, reduces the influence of heat generated by laser source on the measurement accuracy, and makes the system more compact and integrated. The six degree of freedom errors, including position error, horizontal and vertical straightness errors, pitch, raw and roll, can be measured simultaneously by only one incident light. ...

Failure logic modeling method for a high-speed railway train operation control on-board system

The present invention provides a failure logic modeling method for a high-speed railway train operation control on-board system, including the following steps: determining the functional relationship between the structure and the parts of the train control on-board system; analyzing the failures of the parts based on known failures of the train control on-board system in combination with brainstorming; establishing an fmea table to generalize the failures of the parts; editing and simulating the failures by using a modeling tool. By adopting the present invention, the failure modes analyzed are more systematic, and the failure logic modeling can be carried out from a global perspective more easily, the whole process can be better targeted meanwhile, the security analysis complexity of the train control system will be effectively reduced and the development period of the train control system will be shortened.. ...

Train control method for maximizing utilization of regenerative energy

Embodiments of the present invention provide a train control method for maximizing utilization of regenerative energy. The method mainly comprises: working out a matching error Δt of a current matched pair of trains mx (i, j) of a station in the current running situation; and comparing the matching error Δt with a preset maximum adjustable error Δtx of the current matched pair of trains mx (i, j) of the station and determining a strategy for adjusting train running of the current matched pair of trains mx (i, j) according to comparison results.. ...

Complex network-based high speed train system safety evaluation method

The invention discloses a complex network-based high speed train system safety evaluation method. The method includes steps as follows: (1) constructing a network model of a physical structure of a high speed train system, and constructing a functional attribute degree of a node based on the network model; (2) extracting a functional attribute degree, a failure rate and mean time between failures of a component as an input quantity, conducting an svm training using libsvm software; (3) conducting a weighted knn-svm judgment: an unclassifiable sample point is judged so as to obtain a safety level of the high speed train system. ...
