Embodiment

[0090] This embodiment discloses an audio matrix host, such as figure 1 As shown, including CPU, digital audio media matrix, microphone controller, fire alarm, fire linkage, remote controller, trigger controller and strong cut controller;

[0091] In this embodiment, the microphone controller is provided with a plurality of microphone audio input ports, the microphone controller is connected to the CPU, and the audio signal input by the microphone controller audio input port is sent to the CPU; in this embodiment, the microphone controller can use a single-chip microcomputer, etc. microprocessor.

[0092] In this embodiment, the fire alarm is connected to the first memory card that stores the audio signal of the fire alarm; the fire alarm is connected to the CPU, and the CPU controls the fire alarm to read the audio signal from the first memory card, and will read The audio signal is transmitted to the CPU; in this embodiment, the fire alarm can use microprocessors such as si...

Embodiment 2

[0131] This embodiment discloses a public address system, including multiple audio matrix hosts in Embodiment 1, such as Figure 7 As shown, the CPUs in each audio matrix host are cascaded, wherein the first-level CPU is the main CPU, and the other levels of CPUs are slave CPUs; after the main CPU receives each audio signal, it will correspond to the received Each audio signal is transmitted to each slave CPU step by step; at this time, each CPU learns the whereabouts of each audio signal received from the main CPU, that is, the audio area to which each audio signal is to be allocated; for each CPU where the audio Each audio zone of the matrix host compares the priority of each audio signal to be allocated to the same audio zone, and then controls the digital audio media matrix to output the audio signal with the highest priority allocated to the same audio zone to the corresponding audio zone.

[0132] In this embodiment, a total of 32 audio matrix hosts are included, that is...

Abstract

The invention discloses an audio matrix host computer, a public broadcasting system, and working methods thereof. The audio matrix host computer comprises a CPU and a digital audio media matrix, a microphone controller, a fire alarm, a fire linkage device, a trigger controller and an external sound source which are respectively connected with the CPU; the CPU receives audio signals from the microphone controller, the fire alarm, the external sound source and the trigger controller, and then obtains the whereabouts of various audio signals, that is audio zones where various audio signals are distributed to; and for each audio zone, the priority of various audio signals distributed to the same audio zone is compared, and then the digital audio media matrix is controlled to output the audio signal with the highest priority distributed to the same audio zone to the corresponding audio zone. The public broadcasting system comprises a plurality of audio matrix host computers, and the CPUs of various audio matrix host computers are in cascade connection. The audio matrix host computer provided by the invention has the advantages of being simple in structure, and does not need complicated connection, so that the installation space and the use cost are saved.

Description

technical field [0001] The invention relates to a broadcasting system, in particular to a public broadcasting system and an audio matrix host. Background technique [0002] With the continuous progress of the times and the rapid development of science and technology, the functional requirements of modern buildings are significantly different from those of the original buildings, especially with the rapid development of building weak current technology, electronic technology, communication technology, network technology, computer technology, automatic The introduction of a series of the most advanced technologies such as control technology and sensor technology has greatly improved the service function of the building, which is more comprehensive and covers a wider range of fields. As an integral part of the weak current system, public broadcasting is closely related to people's modern life. It can not only play music, but also do business promotion and paging broadcasting. I...
