摘　　要：针对城市轨道交通CBTC系统应答器报文配置数据版本繁多、编制周期长、易出错的问题,研究应答器报文离线生成工具。该工具可根据线路数据计算所有应答器固定报文,并生成应答器配置文件;可通过梳理有源应答器的防护路径和临时限速状态的组合,确定其正常报文数量,依据每种组合中涉及的地面电子单元(LEU)输入信号和设备状态,计算相应掩码和正常报文。此外,根据有源应答器掩码的唯一性,对联锁和地面电子单元接口数据进行验证。掩码验证通过后,该工具将生成包含LEU默认报文与正常报文的LEU配置文件。此报文离线生成工具适用于采用互联互通CBTC信号系统的地铁线路,能够根据更新的线路数据,自动生成应答器报文,提高数据准备效率,降低人工成本。To deal with the problems of numerous versions of balise telegram configuration data,long time period of data preparation,and susceptibility to human errors for the CBTC system of urban rail transit,an offline balise telegram generation tool is developed.The tool can calculate all balises′fixed telegram and generate the balise configuration files based on track data,and determine the count of normal telegram through sorting out all the combinations of the protection routes and temporary speed limit states of a switchable balise.The corresponding mask and normal telegram are calculated according to the input signal and equipment status of the lineside electronic unit(LEU)involved in each combination.And the CBI-LEU interface data is verified in the light of the uniqueness of a switchable balise′s mask.If the mask of one balise passed the verification,the tool will generate the LEU′s configuration file containing the default LEU telegram and normal telegram with masks.The offline balise telegram generation tool can automatically generate balise telegram based on updated track data,which is applicable to metro lines equipped with interoperable CBTC systems and help enhance the efficiency of data preparation and reduce labor costs.
