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 a method and device for receiving RDS. Background technique [0002] The transmission of RDS commands for multi-level emergency broadcasting can be divided into two modes: parallel and cascade. Parallel transmission means that the RDS commands at all levels are independent of each other. There is no first-level signal interruption that causes other signals to be transmitted. The RDS command cannot be transmitted downwards. This transmission method has the disadvantage that the terminal can only hop frequency and receive multi-level signal RDS in time. Command, resulting in the terminal’s frequency cut sound, poor broadcast effect, and low efficiency in responding to RDS commands; cascaded transmission is where the lower level performs differential conversion and merges the upper level transmission, and the terminal only receives the lowest FM frequency point Th...
