The invention discloses a crash recovery system for a audio frequency receiver. The crash recovery system comprises a triggering signal input line, a clock signal output line, a first delay time circuit, a second delay time circuit, a first triode, a second triode, a third triode, a relay, a protection circuit, a power supply and six two-input NAND gates, wherein the six two-input NAND gates comprise a first two-input NAND gate, a second two-input NAND gate, a third two-input NAND gate, a fourth two-input NAND gate, a fifth two-input NAND gate and a sixth two-input NAND gate respectively; the triggering signal input line is connected with two input pins of the first two-input NAND gate; an output pin of the first two-input NAND gate is connected with two input pins of the second two-input NAND gate; and the first delay time circuit comprises a first diode, a first capacitor, a second resistor and a third resistor. Through adoption of the crash recovery system, the receiver can be controlled to restart automatically when the receiver crashes, so that normal transmission of audio signals can be ensured.
Description
technical field [0001] The invention relates to audio transmission technology, in particular to an audio receiver crash recovery system. Background technique [0002] Audio is an important medium for multimedia applications, and the signal is often relayed by a receiver during wireless transmission. When the receiver works for a long time, the phenomenon of crash often occurs. When the receiver crashes, nowadays, the power of the receiver is usually turned off manually, and then restarted. The operation process is cumbersome, time-consuming, and often affects the audio frequency normal transmission of signals. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a recovery system for audio receiver crashes, which can control the receiver to restart automatically when the receiver crashes, thereby ensuring the normal transmission of audio signals. [0004] The present invention solves the abov...
