Description

一种应答器C接口的测试装置 技术领域
本申请要求于2020年10月29日提交中国专利局、申请号为202011181178.2、发明名称为“一种应答器C接口的测试装置”的国内申请的优先权，其全部内容通过引用结合在本申请中。
背景技术
应答器传输模块BTM是应答器传输系统的核心，它通过天线CAU发送能量给轨道上的应答器，并将应答器返回的报文发送到车载自动保护系统ATP。报文经译码后列车控制系统获得坡度、定位、限速等信息，从而实现列车行进的自动控制。
应答器用于向车载ATP提供可靠的地面固定信息和可变信息，包括无源应答器和有源应答器。无源应答器用于提供地面固定信息；有源应答器通过C接口与铁路系统的地面电子单元LEU的连接，可实时改变传送的数据报文。
列控中心TCC根据进路状态、线路参数、临时限速命令等产生进路及临时限速等相关控车信息，并将包括上述控制信息的应答器报文发送至相应有源应答器；LEU用于为列控中心与应答器之间提供通信接口，用于接收列控中心发送的应答器报文并连续向有源应答器转发。
C接口是LEU与有源应答器间的信息传输接口，其在功能上分为C1子接口、C4子接口和C6子接口。C1子接口是LEU向有源应答器传输应答器报文的数据接口；C4子接口用于CAU经过有源应答器期间，由有源应答器产生的信号，用于在规定时间内阻止LEU进行报文转换的接口，其为可选功能；C6子接口是LEU向有源应答器接口电路提供电源的接口。当C接口出现故障时，有可能其中一个信号故障，C接口内只有一个信号；或C接口信号幅度降低，导致信号无法解码。
为了保证应答器能够正常工作，需要对其C接口进行测试。在对应答器的C接口进行测试过程中，需要模拟列车运行状态，使用列控中心TCC、 LEU、应答器连成如图1所示的测试系统。然而该需要设备较多，系统搭建复杂，从而导致测试效率较低。且无法简单的模拟各种报文(单次发送报文、循环发送报文、不间断发送报文、序列报文发送)发送的情况，也无法简单的模拟C接口信号只有C1信号或只有C6信号的情况，也无法简单的模拟不同幅度的C接口信号的情况。

下位机在接收到该反馈信息后将反馈信息发送至上位机，上位机则利用其显示模块向用户显示该反馈信息，该反馈信息包括命令执行情况，能够表征应答器是否正常工作，因此用户通过该反馈信息即可实现对应答器的C接口的测试。另外，该反馈信息还包括C4信号检测情况。
从上述技术方案可以看出，本实施例提供了一种应答器C接口的测试装置，该装置包括上位机和下位机，上位机设置有第一信息交互接口，下位机设置有第二信息交互接口和第三信息交互接口。第一信息交互接口用于向下位机发送控制命令和报文信息，还用于接收下位机返回的反馈信息，上位机还设置有显示模块，显示模块用于显示反馈信息；第二信息交互接口与第一信息交互接口连接，用于接收控制命令和/或报文信息，并向第一信息交互接口发送反馈信息；第三信息交互接口与待测试的应答器的C接口连接，用于向应答器发送C接口信号，并接收应答器返回的反馈信息。相对于现有测试系统，用户在测试时仅需将上位机与下位机连接，并将待测试的应答器的C接口与下位机相连即可实现测试的目的，明显的降低了系统的复杂度，且无需过多操作步骤，从而提高了测试效率。
且能够简单的模拟各种报文(单次发送报文、循环发送报文、不间断发送报文、序列报文发送)发送的情况，也能够模拟C接口信号只有C1信号或只有C6信号的情况，还能够实现简单的模拟不同幅度的C接口信号的情况。
