Embodiment Construction

[0017] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0018] The invention can realize that when some bad reasons occur in the digital broadcasting system during the student's listening test, the machine can automatically switch to the analog 100V backup input channel within 0.3 seconds, realizing the failure of the digital broadcasting system during the listening test. It can automatically switch to the backup 100V input channel when the electricity or network is disconnected, thus ensuring that the listening test of the college entrance examination will not be affected by some unexpected equipment failures in the middle of the test.

[0019] A self-checking self-switching audio system such as figure 1 As shown, it includes an audio detection switching module, a network active speaker and a speaker (not shown in the figure), and the audio detection switching module includes an MCU, a control circuit and a...

Abstract

The invention discloses an audio detection switching module and system. The module comprises a MCU, a control circuit and a relay; the MCU is used for sending a network audio signal from a network active soundbox outside to a loudspeaker outside through a first contact; the network active soundbox outside sends a backup audio signal to the loudspeaker outside through a second contact; the MCU is used for receiving heartbeat data packets sent by the network active soundbox outside in a timed manner, and controlling the first contact to normally close and the second contact to normally open; and the MCU is also used for controlling the first contact to normally open and the second contact to normally close while not receiving the heartbeat data packets within a pre-set time. The audio detection switching module and system disclosed by the invention have the advantages that: the heartbeat data packets are sent to the MCU; the MCU detects whether network connection of the network active soundbox is normal or not in a timed manner; if a failure is detected, a playing channel is switched into backup audio signal input; and thus, the problem that broadcasting cannot be carried out due to network failure can be avoided.

Description

technical field [0001] The invention relates to the audio broadcasting industry, in particular to a technology for switching between main and standby audio source outputs. Background technique [0002] In some important broadcasting occasions, such as listening broadcasting for the college entrance examination, if there is an accident in the broadcasting broadcasting system, such as server failure of the network broadcasting system, disconnection of the network, power outage, etc., resulting in network connection failure and normal broadcasting, it will bring serious consequences. as a result of. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide an audio detection switching module and system, which can solve the problem that the network broadcasting system cannot broadcast normally due to network failure. [0004] The object of the present invention adopts following technical schem...
