In this embodiment, the processing module processes the emergency broadcast information through the RS485 interface or the audio interface, and then sends the generated target broadcast information to the fire-fighting broadcast controller in the fire-fighting broadcast system, the fire-fighting broadcast controller starts the power amplifier in the fire-fighting broadcast system, opens the audio output channel, adjusts the audio signal corresponding to the target broadcast information, adjusts the signal amplitude of the audio signal to 0dB, and drives the speakers arranged on the broadcasting site to broadcast the amplified audio signal to all areas in the building, so that the emergency broadcast information is effectively transmitted.
Further, the broadcasting module 23 in this embodiment further includes a control interface, a communication interface, and a network interface. Optionally, the broadcasting module 23 sends a control instruction to the fire-fighting broadcasting system through a control interface, and controls the starting, sleeping awakening and linkage with other devices of the fire-fighting broadcasting controller through the control instruction, so that the smoothness of emergency broadcasting information transmission is ensured. And, broadcast module 23 sends emergent start feedback information to fire alarm controller or coordinated control ware in the fire control broadcasting system through communication interface to play emergent broadcast information's warning effect through the mode of similar fire alarm formula. Furthermore, the broadcasting module 23 can display equipment state information to the image display device of the fire control room through the network interface, so that when the equipment in the fire control broadcasting system is in an abnormal working state, workers can timely adjust equipment conditions in the fire control broadcasting system according to the equipment state information, emergency broadcasting information can not be normally and timely played due to equipment problems, and effective playing of the emergency broadcasting information is guaranteed.
Further, the broadcast access apparatus in this embodiment further includes a control module 24. The control module 24 is used for coordinating the processing procedures of each component in the broadcast access device, including interface control, encryption and decryption control, broadcasting control and the like. Optionally, the control module in this embodiment may use a mainstream multi-core high-speed processor, and has a rich intelligent processing algorithm built therein. Therefore, the control module enables the broadcast access device to simultaneously receive information in multiple channels, and improves information transmission efficiency. And moreover, by means of a built-in intelligent processing algorithm, automatic allocation of emergency information with different priorities is realized, better emergency information reception is realized, meanwhile, a better overall control function is conveniently realized for each module in the broadcast access device, and the playing efficiency of emergency broadcast information is further improved.
According to the technical scheme, the interface module in the broadcast access device is used for receiving emergency information which is sent by each emergency broadcasting platform in the emergency broadcasting system and comprises emergency broadcasting information and emergency broadcasting instructions, the processing module is used for processing the emergency broadcasting information to generate corresponding target broadcasting information, the broadcasting module is used for transmitting the target broadcasting information to the fire-fighting broadcasting system, and the fire-fighting broadcasting controller is controlled to play audio signals corresponding to the target broadcasting information according to a preset playing mode based on the emergency broadcasting instructions, so that the fire-fighting broadcasting system plays an emergency broadcasting role, the coverage range of the emergency broadcasting is enlarged, and accurate, timely and effective broadcasting of the emergency broadcasting information is further realized.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, and various modifications and variations may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
