Playing unit with fault detection function and public broadcast system with same

Abstract

The invention discloses a playing unit with the fault detection function and a public broadcast system with playing units with the fault detection function, and belongs to the field of public broadcast systems. The public broadcast system comprises a public broadcast system body, a management workstation and a series of playing units with the fault detection function. The public broadcast system body comprises a series of broadcast partitions, the output of the broadcast partitions is connected with the corresponding playing units respectively, and each playing unit is in two-way connection with the management workstation. Each playing unit with the fault detection function comprises a signal processing unit with both the sound transmission function and the fault inquiry signal transmission function, and more than one intelligent loudspeaker with the broadcasting function. The playing unit and the public broadcast system are simple in structure and easy to operate, compared with a traditional method that a power amplifier loudspeaker is used and a sound field detection system is configured at the same time, the method has the advantages that the system cost is greatly reduced, the sound field monitoring effect is improved, the working state of each loudspeaker in each broadcasting partition can be automatically detected while a broadcasting signal is sent, the loudspeaker which breaks down can be detected through the management workstation in real time, and the hardware condition is created for providing efficient broadcast service and meeting emergencies.

Description

technical field [0001] This invention relates to sound reinforcement systems. Background technique [0002] Public address systems are used in airports, stations, hotels, exhibition halls and other public places. The original broadcasting system did not have sound field detection equipment, and it was necessary to regularly detect whether the speakers were faulty, which was inconvenient for maintenance and high in use costs, especially in tall and large spaces, and it was even more difficult to detect the speakers. The improved public address system adds a set of sound field detection system, which is based on the existing broadcast system, and adds a set of sound field detection system. This system needs to be wired separately and works in parallel with the broadcast system. It can detect the fault of the speaker in real time, but There are still problems such as only being able to locate the speaker where the fault point is, but not being able to identify the cause of the...

The original broadcasting system did not have sound field detection equipment, and it was necessary to regularly detect whether the speaker was faulty, which was inconvenient for maintenance and high in cost, especially in tall and large spaces, where it was even more difficult to detect the speaker

The improved public address system adds a set of sound field detection system, which is based on the existing broadcast system, and adds a set of sound field detection system. This system needs to be wired separately and works in parallel with the broadcast system. It can detect the fault of the speaker in real time, but There are still problems such as only locating the speaker where the fault point is, and not being able to identify the cause of the fault.
