Research on Coverage Scheme and Key Technology of Wireless Communication for Cover Development of Urban Rail Transit Parking Lot
[Objective] The cover development design for urban rail transit parking lot is very complicated, requiring more new column grids. Moreover, after the cover development, the omnidirectional antenna set up on the roof of the complex building cannot cover the ground area of the parking lot. In order to...

| description | [Objective] The cover development design for urban rail transit parking lot is very complicated, requiring more new column grids. Moreover, after the cover development, the omnidirectional antenna set up on the roof of the complex building cannot cover the ground area of the parking lot. In order to effectively realize the wireless communication coverage of the parking lot, it is necessary to study the related schemes and key technologies. [Method] Based on the systematic engineering design of TETRA (terrestrial trunked radio) communication system for the parking lot of Textile City Station on Xi’an Metro Line 6 and in view of the difficulties of wireless communication coverage engineering, the frequency planning and allocation scheme of wireless communication system is proposed. A wireless communication coverage scheme is proposed for the parking lot, switch area, access sections and roads in the non-cover area of the parking lot. [Result & Conclusion] FA (frequency allocation) frequency group for wireless communication coverage is adopted for the parking lot of Textile City Station, which ensures frequency interval and avoids same frequency interference. The public security wireless communication system is introduced into the above parking lot, and the scheme of signal route coverage combined with the dedicated wireless communication system is adopted. Directional antenna is used as the coverage mode for the covered parking area to replace the omnidirectional antenna on the roof. Antenna correlation is used for the depot, antenna reinforcement for the throat area, and antenna coverage for U-shaped slot to solve the cross-zone switching , and directional antennas are adopted to cover the surrounding roads by utilizing building sidewalls or columns. The proposed wireless system coverage scheme for the cover development parking lot not only reduces the system interference and the impact on the existing operation, but also effectively solves the problem of the wireless communication coverage for the cover development parking lot, saving the project investment. |
