High bit-error long time-delay network self-adaptive transmission method based on network coding

The invention relates to a high bit-error long time-delay network self-adaptive transmission method based on network coding. A transmitting terminal conducts self-adaptive network coding to transmitted TCP messages according to the magnitude of the flow of a transmission layer and then transmits the coded messages to a receiving terminal. The receiving terminal obtains original messages through network decoding restoration. Since the transmitting terminal conducts redundant coding to the transmitted messages and the receiving terminal can restore the original transmitted messages as long as partial coded messages are received, the impact of high link bit errors on transmission performance is greatly reduced, the transmission protocol throughput is higher, the retransmission rate of the messages is greatly decreased and the transmission performance is greatly promoted. Moreover, since the self-adaptive coding method is adopted, the confidentiality of information is improved. The methodrequires no support from intermediate nodes for transmission, belongs to an end-to-end reliable transmission acceleration method and is compatible with the current popular reliable transmission protocols.

The invention discloses a portable detection device used for measurement of a train wheel tread outline. Through application of the device disclosed by the invention, the high-precision quick measurement of wheel tread wear can be completed. The portable detection device disclosed by the invention is realized by the technical scheme that a stepping motor is used to drive a screw rod and make a nut move along a wheel axis direction; and by a V-shaped spherical guide rail and a profiled motion mechanism, moving of the nut drives a laser displacement sensor to carry out two-dimensional motion in a plane passing a wheel axle, and tracks of the motion copy a standard tread outline of the wheel, so that the tread outline is scanned and measured point by point. The profiled measurement is realized, so that the sensor with a small measurement scope is needed to satisfy measurement requirements for the whole tread outline. Measurement accuracy and resolution are higher. Outline dimensions of an instrument are smaller. The sensor is installed and designed in an inclined manner, so that the problem that the measurement accuracy is reduced or even the measurement cannot be realized thanks to an oversized included angle between a measurement light beam and a normal line of a measured point at a place with a large rate of curve of the tread outline is solved.
