Address defining frequency reducer control signal receiving method and control apparatus of polypoint multi frequency transmitting system

This invention relates to a kind of address defining frequency reducer control signal receiving method and control apparatus of polypoint multi frequency transmitting system. Applies simultaneous system time, to define address frequency reducer for knowing when the head terminal control system send command data to improve its efficiency, and the head terminal control system also knows when the address defining frequency reducer received the sent command, to increase the efficiency of head terminal address defining control system; the said address defining control device comprises micro control unit, digital frequency adjust and de-adjust apparatus, 3-dimensional multi function device, DC power stabilizer, coupler, memory, quartz oscillator and switch, achieving the installation of the address defining frequency reducer, and can receive and view sectional timing program under non-authorized use condition, to achieve advertising effect.
