基于成本费用的铁路无线通信基站设计优化研究

目前,我国铁路无线通信系统设计从整体上考虑优化困难,这在一定程度上制约了铁路的长远发展。在成本结构分析的基础上,以总费用最小、基站数最少为目标,以满足基站无线信号覆盖为主要约束,建立铁路无线通信系统优化模型,并以国内某条已有铁路线为例求得模型的最优解。与已有方案对比表明,新方案不仅大大降低设计费用,而且具有普遍适用性。

Research on the Design Optimization of GSM-R Base Station Based on Cost

At present,the design of Chinese global system for railway mobile communication is difficult for overall optimization,which restricts the railway's long-term development to a certain extent. Based on the analysis of cost structure,an optimization location model is established to minimize the total cost and the number of base station with signal coverage as the main constraint,and an existing railway in China is referenced to find out the optimal solution of the model. Compared with the existing design,the new one not only greatly reduces the design cost,but also sees a wide applicability.
