The embodiment of the invention discloses a radio frequency interference detection method and device. The method comprises the following steps: monitoring a network signal on the surrounding, and generating a first notification message when it is determined that the signal quality of the network signal is lower than a preset first threshold; monitoring an internal current signal, and generating a second notification message when it is determined that the fluctuation degree of the current signal is greater than a preset second threshold; and when the first notification message and the second notification message are obtained, determining that the network signal is abnormal and that the current signal is abnormal, and starting to execute radio frequency interference detection. Therefore, when the network signal is abnormal and that the current signal is abnormal, the radio frequency interference detection is automatically executed to obtain a radio frequency detection result of the radio frequency interference detection, and the radio frequency detection result is reported in time to notify the maintenance personnel to perform radio frequency fault maintenance and position adjustment, therefore the normal operation of the terminal can be restored within the shortest time, and the efficiency of radio frequency fault detection and radio frequency fault maintenance is improved.
