The present invention relates to a system for automatically diagnosing a speaker, and to cope with the problem by wirelessly notifying a speaker that has failed in a broadcasting system using a plurality of speakers.

Hospitals, schools, large concert halls, and intelligent buildings use broadcasting systems that use multiple speakers to deliver announcements and emergencies to speakers.

In this way, since a large number of speakers are installed, it is difficult to identify a failure place when a failure occurs, and thus, a problem arises in that it takes a long time to troubleshoot, and thus the ability to cope with emergencies is reduced.

As a result, there is an increasing demand for easy identification of broken speaker locations.

As described above, if a speaker fails, a circuit for identifying a failure is implemented in hardware. However, when a wired speaker diagnosis circuit is configured, there is a problem in that the cost of hardware increases greatly.

In addition, to solve such a problem, it is possible to determine whether or not the speaker of the corresponding place using a wireless communication method, but even when using this method was not desirable because the hardware increase and cost is great.

In addition, since the transmitted data only needs to process simple data such as ID and fault determination signal, wireless communication of simple hardware configuration was required.

The present invention is to solve this problem

The object of the present invention is to provide an automatic fault diagnosis system of a speaker that can check the abnormality of the speaker by minimizing the hardware configuration and allowing simple data exchange.

Another object of the present invention is to provide an automatic failure diagnosis system for a speaker that can wirelessly control the failure diagnosis of a speaker using a ZigBee wireless module to solve the disadvantages and functional limitations of the existing speaker system.

In particular, ZigBee is a low-power, low-speed, low-capacity wireless communication method that is being spotlighted in recent years, and intends to implement a speaker diagnosis system wirelessly by connecting it with a circuit for diagnosing the early speaker.

An object of the present invention as described above is in a broadcasting equipment system connected to the speaker diagnostic circuit is connected to one side of each speaker, the central speaker diagnostic controller is connected to the other side,

A Zigbee module connected to the speaker diagnosis circuit, a Zigbee module wirelessly connected through the Zigbee module for bidirectional communication, and sequentially receiving or transmitting a signal, and connected to the Zigbee module, and selecting and abnormalizing an object of the speaker. The Zigbee modules may be sequentially transmitted or input in a relay manner.

When described in detail by the accompanying drawings as follows.

1 is a circuit diagram showing an automatic failure diagnosis system of a speaker of the present invention.

The central speaker diagnostic controller 10 is connected to each speaker sp1, sp2, ..., spn.

Here, each of the speakers (sp1), (sp2), ... (spn) is installed in the desired place or room is installed in the corridor or partitioned room of each floor, although not shown, the broadcasting system is connected It is configured to perform the announcement through the speaker (sp1), (sp2), ... (spn).

In addition, each speaker (sp1), (sp2), ... (spn) is connected to the speaker diagnostic circuit (sc1), (sc2), ..... (Sc3), this speaker diagnostic circuit is a broadcasting system Use the hardware commonly used in.

The speaker diagnosis circuits sc1, sc2, ..., and Sc3 are connected to Zigbee modules z1, z2, zn, respectively, and the central speaker diagnosis controller 10. Zigbee module (z10) is also connected to each other through the zigbee modules (z1), (z2), ... (zn) when the speaker (sp1), (sp2), ... (spn) failure The Zigbee module z10 of the central speaker diagnostic controller 10 is configured to identify the fault location.

Fig. 2 shows the relationship of the Zigbee modules z1, z2, ..., zn being communicated by wireless communication.

2 is a communication conceptual diagram for transmitting a fault point through the Zigbee communication in the present invention.

First of all, ZigBee, which is used in the present invention, has established itself as a standard technology for home automation and data networks with low transmission speeds, and has a single button operation to control lighting and home security systems, VCRs anywhere in the house. E. On / Off, etc. can be turned on and standardized in IEEE 802.15.4, and the dual PHY type uses 2.4GHz and 868 / 915MHz frequency bands, and the modem method is a direct sequence spread spectrum (DS-SS). The data transfer rate is 20 ~ 250kbps.

In other words, ZigBee is a concept of a mobile phone or a wireless LAN. A feature different from the existing technology is that it can communicate a small amount of information instead of minimizing power consumption.

In the present invention, the ZigBee (z10) is connected to the central speaker diagnostic controller (10) of FIG. 1, and the speaker (sp1), (sp2), ... (spn) ) Will be detected when an error occurs.

In particular, the Zigbee module as described above uses a relay system that transmits an identification number (ID number) of a speaker where a failure point is generated due to a limitation of the transmission distance to a nearby Zigbee module. 10) will detect the abnormality of the speaker of the corresponding place.

This will be described in detail with reference to FIG. 3.

3 is a flowchart illustrating communication between wireless modules in order to diagnose a failure of a speaker in the present invention.

Initially, in step (s1), the fault spots are diagnosed sequentially by sequentially selecting the fault diagnosis target speaker at a predetermined period. If this fault diagnosis target signal occurs, the fault detection target signal is detected and the next step (s2) is performed. In step S3, the identification signal (ID signal) of the selected target speaker is relayed through the adjacent ZigBee.

In this way, when the identification signal is transmitted through the adjacent zigbee rule in a relay manner, and the fault diagnosis signal is transmitted in the final step at step s4, the fault diagnosis signal is received at step s5, and the magnetism is received at step s6. It is determined whether or not the identification signal ID of?

If it corresponds to the identification signal of its own, it proceeds to the next step (s7) to drive the connected speaker diagnostic circuit.

At this time, the normal speaker diagnostic circuits (sc1), (sc2), ... (scn) accepts a judgment signal ("0" or "1" digital signal) when a hardware failure occurs and corresponds to a failure. If the signal is transmitted in step (s8), and the signal is transmitted in a relay manner in the same manner as the failure diagnosis speaker selection, the signal is transmitted to the central controller through the final Zigbee module (z10) in step (s9). Done.

In this way, it is possible to check whether or not the speaker (sp1), (sp2), ... (spn) of the corresponding location at the regular period by sending and receiving a bidirectional signal.

As above, the target speaker for diagnosis is sequentially selected through the Zigbee module, and the signal according to the speaker abnormality is relayed and applied to the central speaker diagnostic controller to always check whether the speaker is abnormal in real time. It can be repaired in case of trouble.

As described above, the system of the present invention is applicable to speakers installed in hospitals, schools, airports, large concert halls, intelligent buildings, and the like, and has an effect that can be functionally supplemented to various broadcasting systems installed in advance.

In addition, it is possible to secure international markets by developing new technologies related to speaker failure diagnosis and to enhance national competitiveness by pioneering global markets.
