Abstract

The invention provides a RDS receiving method and apparatus, and relates to the technical field of emergency broadcasting. The method comprises the following steps: obtaining a message queue, wherein the message queue comprises a message sent by at least one frequency point; judging whether a heartbeat instruction of target main frequency is received within a preset time period based on the message, wherein the target main frequency is an arbitrary frequency point in at least one frequency point; when it is judged that the heartbeat instruction of target main frequency is not received, switching the target main frequency to a frequency switching list, wherein the frequency switching list at least comprises the last stage of main frequency, and the last stage of main frequency is the last stage of network node in wired frequency modulation networking; polling the frequency switching list to lock the next to-be-switched main frequency, and receiving an RDS instruction through the currently switched main frequency; and detecting whether the target main frequency recovers to be normal, when the target main frequency recovers to be normal, clearing the target main frequency from the frequency switching list. The technical problem that the terminal response is not timely caused by poor transmission effect of the RDS instruction in the existing cascading transmission mode is solved.

Description

technical field [0001] The present invention relates to the technical field of emergency broadcasting, in particular to an RDS receiving method and device. Background technique [0002] The transmission of the RDS command of the multi-level emergency broadcast is divided into two ways: parallel connection and cascade connection. Parallel transmission means that the RDS instructions at all levels are independent of each other, and there is no interruption of the first-level signal to prevent the RDS instructions of other signals from being transmitted downwards. The disadvantage of this transmission method is that the terminal can only hop frequency and receive RDS with multi-level signals in different time periods. Instructions, resulting in frequency-cutting sound at the terminal, poor broadcasting effect, and low efficiency in responding to RDS instructions; cascading transmission is performed by the lower level and combined with the transmission of the upper level, and th...
