[0082] Based on the technical solutions of the above embodiments, this utility model provides several specific implementation methods.

[0083] As one specific implementation method of this embodiment. Figure 7 A schematic diagram of an automatic broadcast frequency modulation transmission system provided for an embodiment of this utility model is shown below. Figure 7 As shown, the main transmitter uses three frequency sources (source 1, source 2, and source 3) as an example. These sources are simultaneously transmitted to the main transmitters (transmitter 1, transmitter 2, and transmitter 3) and the audio switching module. The audio switching module is controlled by the power detection module. When a transmitter at a certain frequency on the main transmitter malfunctions and has no power output, the power detection module sends a corresponding coded command (such as a level signal) to control the audio switching module to switch to the appropriate source. The switched signal source undergoes AOIP encoding processing and is transmitted to the secondary transmitter via a dedicated telecommunication line. After decoding, it is input to the secondary transmitter, thus automatically switching to the audio signal source at the faulty frequency. The transmitter controller communicates with each main transmitter. When a main transmitter malfunctions, it automatically outputs a frequency change command and transmits it to the secondary transmitter via the dedicated telecommunication line, controlling the secondary transmitter to change to the required broadcast frequency and automatically activating the transmitter.

[0084] The system successfully achieved a series of operations, including automatic detection of fault frequencies, automatic switching and transmission of audio signal sources, and automatic switching of the frequency of the standby transmitter, which significantly shortened the emergency standby time and achieved the goal of fully automatic remote standby.
