RFID ADS Automatic Switching System
RFID ADS Automatic Switching System performs the function of automatic switching from AC to DC or DC to AC by detecting RFID Tag information installed in AC/DC neutral section when the train enters AC/DC in neutral section through RFID.
It consists of ADS Controller, RFID Reader, RFID Antenna, RFID Tag and CAM Switch Box.
RFID Tag Detection redundancy System Design
It performs the function of AC/DC automatic switching by processing RFID Tag detected information with a redundancy system of RFID Reader, installed in both front and rear vehicle,
Output Signal Check Back Input Check
ADS Controller checks whether AC / DC switching output operation is normal, by receiving AC / DC switching output signal Feed Back
With Test mode to make detect RFID Tag for test purpose, it checks AC/DC automatic switching movement function.
Broadcast Signal Output to Neutral Section
When to detect RFID Tag in AC/DC neutral section, it performs the function of a broadcast signal output to the neutral section with multi-buzzer.
Storage of Log Operation
It performs the function of input, output signal information from the train, RFID Tag detection, ADS Controller communication state information, storing error information of RFID ADS automatic switching system.
Domestic: Seoul Metro Line-4 EMU
It is the device that controls automatic switching output signal from AC to DC, DC to AC according to RFID Tag detected information from RFID Reader and train input signal condition.
When RFID tag installed in the neutral section is detected, it processes the information and transmits detected tag information to ADS controller.
Being connected with RFID Reader, it transmits received RFID information to RFID Reader, when the RFID tag is detected by outputting the corresponding frequency.
Being installed in the neutral section wayside, it performs the function to output tag information to the RFID Antenna.
CAM Switch Box
It switches CAM switch to AC or DC according to AC DC switching output signal from ADS Controller.
