Abstract

The invention discloses a handheld device and an emergency broadcast receiving method. The handheld device comprises a main system, a power supply module and a broadcast module, wherein the broadcast module comprises a broadcast signal receiving module and a broadcast receiving processor; the power supply module receives a first power supply control signal and a second power supply control signal; the broadcast receiving processor is used for setting receiving parameters of the broadcast signal receiving module, sending the first power supply control signal to the power supply module and sending an awakening signal to the main processor when an emergency broadcast signal is recognized to exist in the broadcast signal; the broadcast signal receiving module is used for receiving the broadcast signal; and the main processor is used for entering an operation mode after the awakening signal is received and sending the broadcast signal to an audio device for being played. As the main processor and the broadcast receiving processor operate independently, the main system can be forced to be awakened even if the main system is in a standby mode, and the emergency broadcast can be ensured to be received timely.

Description

technical field [0001] The invention relates to a handheld device and an emergency broadcast receiving method, in particular to a handheld device with low energy consumption and an emergency broadcast receiving method. Background technique [0002] Emergency broadcasting is also often called emergency broadcasting. When natural disasters, accident disasters, public health and social security and other sudden public crises occur, it will cause or may cause heavy casualties, property losses, ecological environment damage and serious social hazards, endangering In times of public safety, emergency broadcasts provide a quick and easy way to notify. [0003] The Radio Data System (RDS) technology developed based on FM broadcasting technology is widely popularized in EU countries. RDS uses the subcarrier of FM radio to transmit digital signals with a certain bit rate, such as traffic announcements and emergency broadcasts. Emergency broadcasting systems for mines, schools, water...
