The invention discloses a device for rail transit vehicle-mounted controller IO interface adaptation, which comprises a PXI platform, an interface adaptation device and a vehicle-mounted controller, and is characterized in that the PXI platform is in signal connection with the vehicle-mounted controller through radar signals, the PXI platform is used for simulating a real vehicle and a speed measuring device, IO interaction is carried out through a digital IO card and a VOBC, and the interface adaptation device is used for adapting to the interface of the vehicle-mounted controller. A speed pulse is sent to the vehicle-mounted controller through the digital waveform generator, and functions of sending a radar serial port signal and collecting a 0-20mA current signal of the vehicle-mounted controller are realized through other expansion cards; adaptation of IO signals and speed pulses can be flexibly achieved, one-key switching of a dial switch is achieved, the integration level is high, switching of all IOs can be achieved through a double-end VOBC only through one adaptive plug-in box, debugging and verification of an interconnection and intercommunication platform show that the method can adapt to VOBCs of all signal manufacturers in China at present, and the method is suitable for popularization and application. The trouble caused by non-uniform VOBC interfaces of all manufacturers in interconnection, intercommunication and joint debugging is solved.
本发明公开了一种用于轨道交通车载控制器IO接口适配的装置,包括PXI平台、接口适配装置和车载控制器,PXI平台通过雷达信号与车载控制器信号连接,PXI平台用于模拟真实车辆及测速装置,通过数字量IO卡和VOBC进行IO交互,通过数字波形发生器给车载控制器发送速度脉冲,并通过其他扩展卡实现发送雷达串口信号,采集车载控制器的0~20mA电流信号功能;本发明可灵活实现对IO信号,速度脉冲的适配,拨码开关一键切换,集成度高,双端VOBC仅用一个适配插箱即可实现对所有IO的切换,经过互联互通平台调试验证,本发明可适配目前国内所有信号厂商的VOBC,解决了互联互通联调各厂商VOBC接口不统一带来的麻烦。
