This invention discloses a method and system for constructing typical operating conditions of railway locomotive and rolling stock traction systems and components. The method includes: 1) acquiring actual operating data of railway locomotives and rolling stock, forming an original line data table, dividing it into K standard short segments, splicing them together to obtain a standard line, obtaining the corresponding standard line characteristic values, and obtaining the overall line characteristic value based on the standard line characteristic values; 2) dividing the standard short segments into n equal parts according to the cumulative frequency distribution to form n short segment packages, and sequentially extracting short segments from the n short segment packages to form several short segment combinations; 3) calculating the characteristic value of each short segment combination, and performing a non-parametric test with the overall line characteristic value to form a short segment combination to be tested, which is the optimal operating condition; 4) obtaining transient typical operating conditions based on the optimal operating conditions, and obtaining steady-state typical operating conditions. The typical operating conditions of this invention have little difference from actual operating conditions and are suitable for major traction system combination test systems.

This disclosure relates to a road longitudinal matching method, apparatus, device, and computer program product. By acquiring the distance feature points and shape feature points included in both high-precision line segments and candidate standard line segments, the average distance similarity and shape similarity between the high-precision line segments and candidate standard line segments can be determined. The average distance similarity comprehensively considers the average distance from the high-precision line segment to the candidate standard line segment, reducing longitudinal offset caused by positional accuracy errors at the beginning and end points of the standard line segment. The shape similarity enables matching based on shape, reducing longitudinal offset caused by shape differences. Therefore, based on the average distance similarity and shape similarity, a standard line segment that matches the high-precision line segment can be determined, reducing longitudinal offset and improving driving safety.

A method and apparatus is proposed for performing the ONU activation process in a PON having a standard line rate of 50G or higher. The method and apparatus are based upon having the OLT instruct any activating ONUs to transmit at a line rate that is less than 50G, which allows for an OLT receiver without any particular equalization configuration to accurately recover the upstream burst-mode transmissions from the activating ONUs. Once the activation process is completed, the OLT may instruct the new ONUs to reset their transmitters to operate at the higher line rate of the PON. Alternatively, at the end of the activation process, the new ONUs may be configured to automatically reset their transmitters to higher line rate.
