Design Scheme of AP Station Layout in an Urban Rail Signal System

A station layout design scheme takes line environment data provided by subway users as the input, carries out wireless signal coverage quality simulation calculations according to a wireless channel propagation loss model, and outputs the preliminary layout scheme of AP for the entire line. The input data include the electromagnetic environment parameters of data communication system equipment, the physical environment data on site, and the technical parameters and requirements of wireless transmission transceiver equipment. According to a preliminary layout scheme, a simulation analysis is carried out, and a graphical indication of the wireless coverage performance of each point in the entire line is given, which provides analysis data for network optimization. On this basis, a typical environment of the project site is surveyed, the wireless coverage simulation results are calibrated using survey data, and the final project implementation layout plan is output. The purpose of this scheme is to reduce the workload of AP equipment installation and testing.
