The invention discloses ground electronic equipment, belonging to the field of signal equipment in railway communication. The equipment of the invention comprises a communication unit, a control unit, an input decoding unit and an amplification detection output unit; the communication unit is connected with the control unit and is used for connecting an external communication line and sending or receiving communication data; the control unit is connected with the input decoding unit and the amplification detection output unit respectively and is used for controlling all units to output the data decoded by the input decoding unit and output control signal which is amplified by the amplification detection output unit; the input decoding unit is connected with the decoded signal input end ofthe control unit and is used for connecting a responder communication line, decoding the low-frequency signal which is fed back by the responder and then transmitting the decoded low-frequency signalto the control unit; the amplification detection output unit is connected with the control unit and is used for amplifying the control signal of the control unit and then outputting the amplified control signal. The ground electronic equipment can accurately monitoring the working state of the responder from a long distance.
