关于对特殊区段报文的处理和载频掉码的处理方面的翻译文件

47、系统需求中没有说明ATP与LKJ之间传输的数据（报告编号ATPR--00080）
System requirements fail to state data between ATP and LKJ (report No. ATPR--00080)
由于LKJ属于系统之外的设备，我们在系统需求中除了需要说明硬件接口之外，也应该规定ATP与LKJ之间传送的数据。通过LKJ-2000～ATP接口规格书可知，ATP需要向LKJ传送车次号、司机ID、目标速度、目标距离、控制命令状态、报警信息、空转滑行信息、ATP故障信息、地面设备故障信息以及列车位置、运行速度、限速等信息。另外LKJ也会向ATP传送一些数据，这些数据会作为ATP的输入数据，需要我们的系统进行相应处理。所以建议在系统需求中对这些传输数据进行说明，让设计阶段的人员清楚我们开发的系统都有哪些外围数据，我们需要提供给外界什么数据。至于这些数据怎么使用，怎么发送应该是设计阶段的工作。
Because LKJ does not belong to the system, the system requirements should not only state the hardware interface, but also state the data transmitted between ATP and LKJ. The LKJ-2000~ATP interface specification shows ATP is required to transmit to LKJ information such as vehicle number, driver ID, target distance, control order status, alarm, blank running and sliding, ATP fault, ground equipment fault, train position, running speed and speed restriction. LKJ will also transmit some data to ATP. These data will be taken as ATP input data and needs corresponding treatment by the system. So suggest give statement on these transmitted data in the system requirements. This is to enable design personnel to understand what external data the system has and what data to be provide to the external. As for how to use these data and how to transmit them, this will be done in the design period.

Beijing Chinese Subtitling Translation Service Agency has translated many technical documents about For special section message handling and carrier frequency off code processing.

48、系统需求中没有对特殊区段报文的处理（报告编号ATPR--00081）
System requirements have no treatment to messages in special section (report No. ATPR--00081)
应答器报文定义中有ETCS-68包报文，其内容为特殊区段。查询系统需求没有发现对此报文的相关处理要求。如果系统不进行处理，应该在系统需求中明确说明。
The balise message definition has ETCS-68 package message. The content is in special section. The result of searching the system requirements shows there is no relevant treatment requirement for such message. If the system does not treat the message, the system requirements should give clear statement.

49、系统需求中没有说明载频掉码的处理（报告编号ATPR--00084）
System requirements fail to state treatment to omission of codes in carrier frequency (report No. ATPR--00084)
系统需求R-SYS-A-041中规定了掉码时间为4.0±0.1 (s)，在需求中没有说明掉码后应该如何处理。在主体机车信号系统技术条件（暂行）的6.8.1条款中的规定为“任何信息掉码大于10s，只接收载频切换信息码（25.7Hz），其他信息停止接收”。建议系统需求中也明确掉码的处理。
The system requirement R-SYS-A-041 states the time of code omission is . The requirement fails to state how to treat the omission. Article 6.8.1 of the main cab-signaling system technical condition (temporary) states “if any information omitting codes lasts for more than 10 seconds, only receive the carrier frequency switched information code (25.7Hz) and stop receiving other information.” Suggest the system requirements specify how to treat the code omission.
