Transmitter amplitude modulation remote monitoring and alarm device

The utility model provides a transmitter amplitude modulation remote monitoring and alarm device including an amplitude modulation monitor, a signal amplification unit, a triode, a relay, a radio transmission module and an alarm. The amplitude modulation monitor is electrically connected with the signal amplification unit. The amplitude modulation monitor has a threshold range. When an amplitude modulation change of a transmitter detected by the amplitude modulation monitor exceeds the threshold range, the amplitude modulation monitor sends a signal, and the signal amplification unit receives the signal of the amplitude modulation monitor. The triode is electrically connected between the signal amplification unit and the relay. The relay comprises a pull switch. The radio transmission module is electrically connected with the relay. The alarm is arranged on a control end of the remote transmitter. The alarm and the radio transmission module conduct signal transmission. The device can monitor the transmitter remotely and gives an alarm according to the amplitude modulation change of the transmitter. The device is convenient and practical, improves safe operation of the transmitter, and facilitates quick determination and maintenance of transmitter faults.
