Main and backup line switching system for radio frequency adapter and transmitter and implementation method thereof

The invention discloses a main and backup line switching system for a radio frequency adapter and a transmitter and an implementation method thereof. Based on the characteristics of high speed and always online of the GPRS (general packet radio service) wireless communication technology and by means of a network, the switching between main and backup lines can be realized so that the equipment maintenance does not occupy the use time of users, the normal maintenance and overhaul of the equipment can be realized in the mode of switching between the main line and the backup line; a remote monitoring center monitors the parameters of each component of the system in real time through a GPRS wireless monitoring unit and sends control instructions to each component through the GPRS wireless monitoring unit so as to timely alarm and solve the problem. By the adoption of the invention, the traditionally manned patrol mode is changed, human resource is saved, and the problem that transmitters are widely distributed, mostly distributed in rural and remote areas with complicated surrounding environments and are in an unattended state can be overcome.
