The invention discloses a point-mode train control system signal output device and an antenna detection method, the output device comprises a double-CPU electronic circuit (1) and a first frequency power output and re-detection circuit unit, the first frequency power output and re-detection circuit unit is connected to a first coil of a vehicle-mounted antenna. The first frequency power output and re-detection circuit unit is used for outputting a wave power signal of a first frequency to the first coil. According to the power signal output device, whether the functional circuit breaks down or not can be judged in the device, whether the external vehicle-mounted antenna is in an open-circuit fault state or a short-circuit fault state or not can be judged, and the impedance of the external vehicle-mounted antenna can be judged to be in a decreasing state. And the power signal output device reports the functional circuit state, the vehicle-mounted antenna state and the impedance drop state to an external logic processing unit or other units with communication functions in a point-to-point communication or communication bus mode.
