This paper introduces the planning and construction of emergency FM broadcasting （＂Village Ring＂ Project） in Dali, Yunnan province. The emergency FM radio network is built based on the cable TV transmission network, the broadcasting platform of Dali People＇s Broadcasting Station and the FM broadcasting network in Dali, including all townships and administrative villages. Adding RDS addressable control signals and GPRS / GSM emergency broadcasting controlling signals to transmission signals is in order to manage and control FM receiving/enlarging equipment （big horns） in 12 counties （cities） and 1078 administrative villages. When emergent events and natural disasters take place, we could broadcast the emergency radio signal to the public by receiving/enlarging terminal equipment through the FM broadcasting network.
