TD-SCDMA与Femtocell矿井通信系统的设计与分析

Design and analysis of TD-SCDMA and Femtocell in mine communication system

针对我国煤炭能源行业信息化的业务特点和发展需求,并结合当前TD-SCDMA通信技术的特点,提出基于TD-SCDMA技术的煤炭通信专网系统,再分析Femtocell技术的潜在优势,提出基于Femtocell技术的矿用无线通信系统。分析两种通信系统方案的特点,并对两种系统方案在矿井通信中的适用性和可行性做了详细的对比。结果表明:基于Femtocell技术的无线矿用通信系统方案在工程的部署和技术的成熟度方面具有很多不足,而基于TD-SCDMA技术的专网煤炭系统方案在工程规划设计方面,符合煤矿特殊作业的要求,并在布网实施方面具有很高的可操作性,满足矿井特殊环境对通信的需求,因此作为煤矿企业首选的矿井无线通信解决方案成为必然。

According to the characteristics of the coal industry informatization development needs and business,combination of TD-SCDMA and Femtocell technology advantage, put forward a mine wirelesscommunication system based on Femtocell and coal private network communication system based onTD-SCDMA. This paper analyzed the characteristics of two kinds of communication system solutionsand compared the applicability and feasibility of the two systems in detail. Results of the contrast showedthat there are still plenty of shortcomings in wireless communication system based on Femtocell; on theother hand, coal enterprise network system based on TD-SCDMA has the high feasibility form plan toimplementation, completely accords with the requirements for communication of special environmentin coal mine, and it can be the preferred solution of mine wireless communication system for coalenterprises.
