, Description:TECHNICAL FIELD
[0001] The present disclosure relates to public address broadcasting system. More particularly, the present disclosure relates to system and device for fault detection for public address broadcasting.

BACKGROUND
[0002] The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] In general, public address means premises broadcasting such as apartment complex, school, government office, large building, harbour, airport, etc., and is used for emergency broadcasting in case of emergency such as fire. For example, public address systems can notify people through loudspeakers in the event of an emergency such as a fire and induce safe evacuation to minimize human injury. Expensive and high-end audio systems are being used worldwide in multiple locations like cinemas, auditoriums, airports, entertainment parks etc. These installations often involve multiple amplifiers and speakers spread over large areas. Often times, when some of these amplifiers and speakers fail, they are not detected and the system keeps running in a compromised manner.
[0004] These installations are often in remote locations, and the existing operations staff are not trained to detect exact faults. Hence engineers have to travel from long distances to first detect the fault. They have to make a second visit to fix the fault once the spares are procured. During these interim periods, the system operates in a compromised fashion. Sometimes events and shows have to be cancelled for days.
[0005] Existing techniques require an expert user to manually detect all the speakers or amplifier to detect and remediate the detected fault. Therefore, if the number of speakers and amplifiers are huge, then in that case fault detection and remediation will be a cumbersome task. Further, there are existing techniques that involve introducing a certain monitoring device or apparatus that monitors the public address (PA) system as a whole for any faults, however this hardware, apparatus, device etc. interferes with operations of the PA system. If any of these devices, apparatuses becomes faulty, then operation of the whole PA system is affected
[0006] There is, therefore, a need in the art to provide a system and a device that can help detect the failures of amplifiers and speakers and provide alerts about the failed component on a real-time basis during the operation of the PA system without affecting the operation of the PA system.

[0050] FIG. 1 illustrates an exemplary network architecture of an overall system for fault detection for public address (PA) broadcasting in accordance with an embodiment of the present disclosure.
[0051] As illustrated in network implementation 100, a server 102 (interchangeably referred to as central server 102 of remote server 102 herein) can be operatively coupled with multiple systems for detecting fault for public address broadcasting 106-1, 106-2…..106-N (collectively referred to as fault detecting systems 106 or system 106 herein, and individually referred to as fault detecting system 106 or system 106 herein) through a network 104.
[0052] Further, the network 104 can be a wireless network, a wired network or a combination thereof. The network 104 can be implemented as one of the different types of networks, such as intranet, local area network (LAN), wide area network (WAN), the internet, Wi-Fi, LTE network, CDMA network, and the like. Further, the network 106 can either be a dedicated network or a shared network. The shared network represents an association of the different types of networks that use a variety of protocols, for example, Hypertext Transfer Protocol (HTTP), Transmission Control Protocol/Internet Protocol (TCP/IP), Wireless Application Protocol (WAP), and the like, to communicate with one another. Further, the network 104 can include a variety of network devices, including routers, bridges, servers, computing devices, storage devices, and the like.
[0053] In an embodiment, the server 102 can interact with a plurality of set of devices 108-1, 108-2……108-N (collectively referred to as multiple sets of fault detecting devices 108 or multiple sets of devices 108 herein, and individually referred to as set of fault detecting devices 108 or set of devices 108 herein) incorporated with corresponding system 106.
[0054] Further, the server 102 can interact with a plurality of set of amplifiers and speakers 110-1, 110-2……110-N (collectively referred to as multiple sets ofamplifiers and speakers 110 or multiple amplifiers and speakers 110 herein, and individually referred to as amplifiers and speakers 110 or amplifiers and speakers 110 herein) incorporated with corresponding system 106.
[0055] In an embodiment, the system 106 can monitor in real-time various parameters associated with the set of amplifiers and speakers 110 using the set of devices 108. Each of the set of devices 108 can be configured to extract various parameters from audio signals being transmitted to the set of amplifiers and speakers 110 for broadcasting operation. The various parameters can include various power component of the audio signal being transmitted. The various parameters can include but are not limited to a voltage, a resistance, an impedance, a power, a current and the like.
[0056] In an embodiment, the extracted parameters are then compared with a predefined threshold range, wherein the threshold range can be defined by upper threshold value and a lower threshold value of the parameters. If the extracted parameters fall between or intermediate the threshold range for the extracted parameter then the operation of the corresponding amplifier or speaker of the set of amplifiers and speakers 110 is considered normal. However, based on comparison ff the extracted parameters fail to fall between or intermediates the threshold range for the extracted parameter then the operation of the corresponding amplifier or speaker of the set of amplifiers and speakers 110 is considered faulty. Now, based on detection of a faulty speaker and/or amplifier an alert can be generated corresponding to the detected faulty speaker and or amplifier.

In another embodiment, the server 202 can form part of a network of a plurality of systems located at various or different geographic locations. In yet another embodiment, the network of the plurality of systems can be located locally with a single premise, i.e. having similar geographic location or can be located at different geographic locations.
[0060] In an embodiment, the system 200 can include an audio processing or generating unit 204 for generating an audio signal. The generated audio signals can be transmitted to a set of crossovers 206 to create a stream of audio signals consisting of separated bands of high-, mid-, and low-range frequencies. The different bands of frequencies feed the different speakers, or “drivers,” in a sound system: tweeters, woofers, and subwoofers.There are two basic kinds of crossovers 206: active and passive. Passive crossovers don’t need the power to filter the signal as desired. Active crossovers require power and ground connections but provide much more flexibility and fine-tuning control ofaudio signals.
[0061] Further, the system can include a fault detection device 212 (interchangeably referred to as device 212 herein) for detecting faulty amplifier from plurality of amplifiers 208-1, 208-2 and 208-3 (collectively referred to as amplifiers 208 or amplifier units 208 herein, and individually referred to as amplifier 208 or amplifier unit 208 herein) or a faulty speaker from plurality of speakers 210-1, 210-2….210-15 (collectively referred to as speakers 210 or audio broadcasting units 210 herein, and individually referred to as speaker 210 or audio broadcasting unit 210 herein).

[0063] Further, the extracted parameters can then compared with a predefined threshold range, wherein the threshold range can be defined by upper threshold value and a lower threshold value of the parameters. If the extracted parameters fall between or intermediate the threshold range for the extracted parameter, then the operation of the corresponding amplifier or speaker of the amplifiers 208 and speakers 210 is considered normal. However, based on comparison ff the extracted parameters fail to fall between or intermediates the threshold range for the extracted parameter then the operation of the corresponding amplifier or speaker of the amplifiers 208 and speakers 210 is considered faulty. Now, based on detection of a faulty speaker and/or amplifier an alert can be generated corresponding to the detected faulty speaker and or amplifier.

The impedance unit 214 can include but not limited to any or a combination of a resistor, a capacitor and an inductor. It would be appreciated by the person skilled in the art that the impedance unit 214 is selected such that the impedance of the impedance unit 214 does not affect the audio broadcasting operation of the overall system.

[0072] Embodiments of the present disclosure may be implemented entirely hardware, entirely software (including firmware, resident software, micro-code, etc.) or combining software and hardware implementation that may all generally be referred to herein as a “circuit,” “module,” “component,” or “system.” Furthermore, aspects of the present disclosure may take the form of a computer program product comprising one or more computer-readable media having computer-readable program code embodied thereon.
[0073] Thus, it will be appreciated by those of ordinary skill in the art that the diagrams, schematics, illustrations, and the like represent conceptual views or processes illustrating systems and methods embodying this invention. The functions of the various elements shown in the figures may be provided through the use of dedicated hardware as well as hardware capable of executing associated software. Similarly, any switches shown in the figures are conceptual only. Their function may be carried out through the operation of program logic, through dedicated logic, through the interaction of program control and dedicated logic, or even manually, the particular technique being selectable by the entity implementing this invention. Those of ordinary skill in the art further understand that the exemplary hardware, software, processes, methods, and/or operating systems described herein are for illustrative purposes and, thus, are not intended to be limited to any particular named.
[0074] As used herein, and unless the context dictates otherwise, the term "coupled to" is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms "coupled to" and "coupled with" are used synonymously. Within the context of this document terms "coupled to" and "coupled with" are also used euphemistically to mean “communicatively coupled with” over a network, where two or more devices are able to exchange data with each other over the network, possibly via one or more intermediary device.
[0075] It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refers to at least one of something selected from the group consisting of A, B, C …. and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
[0076] While the foregoing describes various embodiments of the invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof. The scope of the invention is determined by the claims that follow. The invention is not limited to the described embodiments, versions or examples, which are included to enable a person having ordinary skill in the art to make and use the invention when combined with information and knowledge available to the person having ordinary skill in the art.
