The utility model discloses a remote monitoring device for synchronous frequency modulation emission points of broadcasting, which comprises at least a remote data collecting terminal, a background management terminal and a mixing network transmission device. Separate remote data collecting terminals and background management terminals are respectively connected with the mixing network transmitting device through a serial communication port to which a standard RS-232 mode is applied and an 10 Mbps Ethernet port for communication. As the utility model applies the remote data collection centered on a single chip microcomputer, works in three communication ways of TCP/IP Ethernet communication, Modem communication and GSM short message communication, and forms a remote monitoring system by cooperating with the monitoring software at a broadcasting control center, the utility model can conveniently dynamically monitor separate frequency modulation emission points in real-time and provide accurate and timely data analysis for each frequency modulation emitting point with flexible and diversified modes of transmitting data, thus connecting all frequency modulation emitting points into a large information network and ensuring that the management and maintenance personnel know the operation condition of the broadcasting system at any time.
