AI Technical Summary

Technical Problem

Existing switching devices cannot handle combined transmitter and antenna failures, lack detection of antenna operating status and transmitter power status, and the long-term idleness of backup transmitters leads to resource waste.

Method used

A switching device that simultaneously supports dual antennas and dual transmitters as primary and backup is designed. The control module controls the RF switcher and power detector to realize the switching between dual antennas and dual transmitters as primary and backup. The device detects the working status of the antennas and transmitters and uses an interlocking function to prevent transmitter damage caused by improper switching.

Benefits of technology

It improved the stability and resource utilization of broadcast television programs, extended the overall lifespan and stability of the transmitter, balanced the aging rate of the transmitter, and avoided resource waste.
