The embodiment of the application provides an audio amplifier system, as shown in fig. 1, the audio amplifier system includes a master audio amplifier and at least two slave audio amplifiers. The middle loudspeaker boxes of the loudspeaker box system form a total loop in a wireless communication mode. Certainly, the main sound box can interact with a user terminal (mobile phone) to receive instructions and audio files transmitted by the user terminal, the files and the instructions can be transmitted in a loop according to a preset sequence, the main sound boxes are not required to be sent one by one, and the sending frequency is reduced.

The wireless communication mode in the embodiment of the application can be bluetooth, and can also be other wireless communication modes such as wifi, 3G, 4G and 5G. In one possible implementation, the instructions and audio files may be propagated in the loudspeaker system in the form of instruction frames and audio frames, respectively. The at least two slave loudspeaker boxes are arranged according to a preset sequence, and the preset sequence is the transmission sequence of the audio frames and/or the detection frames.

Optionally, the Protocol of the instruction frame and the audio frame in this embodiment may be a User Datagram Protocol (UDP).

As shown in fig. 1, three speakers form a loop for example. The connected sound box is used as a main sound box, and other sound boxes are used as auxiliary sound boxes. The audio playing process is as follows: firstly, connecting a mobile phone with a main sound box, wherein the main sound box plays Bluetooth music; secondly, when the master loudspeaker box plays, the master loudspeaker box transmits the Bluetooth audio to the slave loudspeaker box 1 through UDP, and the slave loudspeaker box 1 plays Bluetooth music; and thirdly, when the slave loudspeaker box 1 plays, the slave loudspeaker box 1 transmits the Bluetooth audio to the slave loudspeaker box 2 through UDP, and the slave loudspeaker box 2 plays Bluetooth music.

It should be noted that, for convenience of illustration, only two slave speakers are shown in fig. 1, and the number of slave speakers is not limited herein. In a possible implementation manner, the identities of the master speaker and the slave speakers may be interchanged, and the speaker that is currently interacting directly with the user terminal is determined as the master speaker.

The embodiment of the application provides an electronic device, which can be a sound box device, such as a master sound box and a slave sound box in fig. 1. Please refer to fig. 2, a schematic structural diagram of an electronic device. The electronic device comprises a processor 10, a memory 11, a bus 12. The processor 10 and the memory 11 are connected by a bus 12, and the processor 10 is configured to execute an executable module, such as a computer program, stored in the memory 11.

The processor 10 may be an integrated circuit chip having signal processing capabilities. In the implementation process, the steps of the sound box system fault location method may be completed by an integrated logic circuit of hardware in the processor 10 or instructions in the form of software. The Processor 10 may be a general-purpose Processor, and includes a Central Processing Unit (CPU), a Network Processor (NP), and the like; the device can also be a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other Programmable logic device, a discrete Gate or transistor logic device, or a discrete hardware component.

The Memory 11 may comprise a high-speed Random Access Memory (RAM) and may further comprise a non-volatile Memory (non-volatile Memory), such as at least one disk Memory.

The bus 12 may be an ISA (Industry Standard architecture) bus, a PCI (peripheral Component interconnect) bus, an EISA (extended Industry Standard architecture) bus, or the like. Only one bi-directional arrow is shown in fig. 2, but this does not indicate only one bus 12 or one type of bus 12.

The memory 11 is used for storing programs, such as programs corresponding to the sound box system fault locating device. The sound box system fault locating device comprises at least one software functional module which can be stored in a memory 11 in the form of software or firmware (firmware) or solidified in an Operating System (OS) of the electronic equipment. After receiving the execution instruction, the processor 10 executes the program to implement the sound box system fault location method.

Possibly, the electronic device provided by the embodiment of the present application further includes a communication interface 13. The communication interface 13 is connected to the processor 10 via a bus. The electronic device may interact with other terminals via the communication interface 13.

It should be understood that the structure shown in fig. 2 is merely a structural schematic diagram of a portion of an electronic device, which may also include more or fewer components than shown in fig. 2, or have a different configuration than shown in fig. 2. The components shown in fig. 2 may be implemented in hardware, software, or a combination thereof.

The method for locating a fault of a sound box system provided in the embodiment of the present application can be applied to, but is not limited to, the main sound box shown in fig. 1, and with reference to fig. 3, the method for locating a fault of a sound box system includes: s103, S104, and S105.

And S103, under the condition that the total loop fails, the main sound box generates a first target transmission sequence corresponding to the target loop.

The target loop comprises at least one target sound box, the target sound boxes are slave sound boxes in the total loop, the number of the target sound boxes is smaller than the total number of the slave sound boxes, and the target loop is a loop consisting of a master sound box and all the target sound boxes.

Referring to fig. 4, fig. 4 is a schematic diagram of a total loop when the number of slave speakers is 2. Taking fig. 4 as an example for explanation, the target loudspeaker may be the slave loudspeaker 2 in fig. 4. The target loop may be a loop consisting of a master enclosure and a slave enclosure 2. The first target delivery sequence may be from the main enclosure to the slave enclosure 2 to the main enclosure.

It should be noted that the number of target speakers in the target loop may be greater than or equal to 2, the above example is only used as an example for illustration, and the number of target speakers is not limited, and the following is the same.

When there are multiple target enclosures (e.g., including slave enclosure a, slave enclosure B, slave enclosure C, and slave enclosure D), in order to facilitate the target enclosures to know the transfer order of the sounding frames, it is necessary to set a first target transfer order, e.g., master enclosure to slave enclosure a to slave enclosure B to slave enclosure C to slave enclosure D to master enclosure. The loop can be understood as a circular loop with the main sound box as a starting point and the main sound box as an end point.

And S104, the main loudspeaker box sends a first detection frame in the target loop.

Wherein the first sounding frame includes a first target delivery order.

Optionally, the first target delivery order is used for the target speaker to transmit the probe frame on the target loop along the delivery order when receiving the probe frame from the main speaker.

Continuing with the above example, when all nodes (slave enclosures) in the target loop are normal (not malfunctioning). When the slave loudspeaker box A receives the first detection frame transmitted by the master loudspeaker box, the slave loudspeaker box A can know the first target transmission sequence carried in the first detection frame, the slave loudspeaker box A should transmit the first detection frame to the slave loudspeaker box B, and the rest is done in the same way. And when the slave loudspeaker box D receives the first detection frame transmitted from the loudspeaker box C, the slave loudspeaker box D transmits the first detection frame back to the master loudspeaker box.

S105, under the condition that the main sound box does not receive the first detection frame returned by the target loop in the first time interval, the main sound box positions the fault node from the target loop.

It can be understood that, when the main speaker does not receive the first probe frame returned by the target loop within the first time interval, it indicates that there is a faulty node in the target loop, and it is necessary to further locate the faulty node from the target loop. The first time interval is the time interval from the current time to the time when the main loudspeaker box sends out the first detection frame.

Compared with the method that the main sound box sends the detection message to each slave sound box, the sound box system fault positioning method provided by the embodiment of the application can effectively reduce the sending number of the messages. Possibly, because the detection frames can only be sent frame by frame in sequence, and the time consumed for sending the multiple frames is too long, the embodiment of the application can also save the sending time of the message and quickly position the fault node.

To sum up, the embodiment of the present application provides a method for locating a fault of a sound box system, which is applied to a main sound box of the sound box system, wherein the sound box system further includes at least two slave sound boxes, the main sound box and the at least two slave sound boxes form a main loop in a wireless communication manner, and the method for locating a fault of a sound box system includes: under the condition that the main loop fails, the main sound boxes generate a first target transmission sequence corresponding to a target loop, wherein the target loop comprises at least one target sound box, the target sound boxes are slave sound boxes in the main loop, the number of the target sound boxes is smaller than the total number of the slave sound boxes, and the target loop is a loop consisting of the main sound boxes and all the target sound boxes; the main sound box sends a first detection frame in a target loop, wherein the first detection frame comprises a first target transmission sequence; and under the condition that the main sound box does not receive the first detection frame returned by the target loop in the first time interval, the main sound box positions the fault node from the target loop. The loudspeaker box system fault positioning method provided by the embodiment of the application can effectively reduce the sending number of the messages, save the sending time of the messages and quickly position the fault node.

On the basis of fig. 3, in order to accurately locate the fault node, the embodiment of the present application further provides a possible implementation manner, please refer to fig. 5, and the method for locating a fault in a sound box system further includes S106.

And S106, under the condition that the main sound box receives the first detection frame returned by the target loop in the first time interval, the main sound box generates a first target transmission sequence corresponding to a new target loop.

As described above, when the master speaker receives the first probe frame returned by the target loop within the first time interval, it indicates that all slave speakers in the target loop are working normally. At this time, the fault node needs to be located from other slave speakers in the total loop.

In a possible implementation manner, the slave loudspeaker box only has the slave loudspeaker box 1 and the slave loudspeaker box 2 as shown in fig. 1, when the total loop has a fault, the slave loudspeaker box 2 is tested, and when the slave loudspeaker box 2 transmits the first detection frame back to the master loudspeaker box, the slave loudspeaker box 1 can be directly determined as a fault node.

In one possible implementation, when a target loop composed of multiple target speakers (e.g., including speaker a, speaker B, speaker C, and speaker D) successfully returns the first probe frame, if the total loop also includes speaker a, speaker B, speaker C, and speaker D. Optionally, one or more of the slave loudspeaker boxes a, the slave loudspeaker box b, the slave loudspeaker box c and the slave loudspeaker box d may be combined into a new target loop, and a first target delivery sequence corresponding to the new target loop may be generated.

In one possible implementation, the new target loop may be a slave loudspeaker node that has no cross-coverage with the historical target loop, or may be a slave loudspeaker node that has cross-coverage. Illustratively, the new target loops include Slave enclosure A, Slave enclosure B, Slave enclosure C, and Slave enclosure A, and the historical target loops include Slave enclosure A, Slave enclosure B, Slave enclosure C, and Slave enclosure D, both of which include Slave enclosure A, illustrating cross-over of the two. The historical target loop may be a loop that has already performed the first sounding frame sounding.

In one possible implementation, in order to reduce the message sending frequency, the new target loop and any historical target loop do not intersect with each other. It should be noted that, nodes in the historical target loop have been verified and have not failed, and in order to reduce the complexity of verification, it is not necessary to repeatedly verify the nodes in the historical target loop, so that the new target loop and the historical target loop do not have cross coverage slave loudspeaker nodes, that is, the slave loudspeaker in the new target loop does not belong to any historical target loop.

After S106, S104 is repeatedly executed to determine whether a failed node exists in the new target loop.

When the target loop includes at least two slave speakers, the embodiment of the present application further provides a possible implementation manner for the content in S105, please refer to fig. 6, where S105 includes S105-1 to S105-5.

S105-1, the main sound box splits the target loop into at least two sub-loops.

In order to accurately locate a fault node from a target loop, the target loop needs to be split into at least two sub-loops. For example, the current target loop includes slave speaker A, slave speaker B, slave speaker C, and slave speaker D, and correspondingly, the sub-loops may be slave speaker A and slave speaker B, slave speaker C, and slave speaker D, respectively. The current target loop comprises a slave loudspeaker box A and a slave loudspeaker box B, and correspondingly, the sub-loops can be the slave loudspeaker box A and the slave loudspeaker box B respectively.

And S105-2, the main sound box sequentially sends a second detection frame in each sub-loop till the fault sub-loop is determined.

The second detection frame comprises a second target transmission sequence corresponding to the sub-loop, and the fault sub-loop is a sub-loop of the second detection frame which is not received by the main loudspeaker in the first time interval. It will be appreciated that the second targeted delivery order is of the same form and differs in content from the first targeted delivery order.

Alternatively, the transmission path of the second sounding frame may still refer to fig. 4.

And S105-3, the master loudspeaker box judges whether the number of the slave loudspeaker boxes in the fault sub-loop is more than 2. If yes, executing S105-5; if not, S105-4 is executed.

It can be understood that the number of slave loudspeaker boxes in the fault sub-loop is less than 2, that is, the number is 1, at this time, the slave loudspeaker boxes in the fault sub-loop can be determined as fault nodes, that is, S105-4 is performed; otherwise, a further determination of the failed node is required, i.e. S105-5 is performed.

And S105-4, determining the slave loudspeaker boxes in the fault sub-loop as fault nodes.

And S105-5, splitting the fault sub-loop into at least two new sub-loops.

After S105-5, S105-2 is repeatedly executed until the number of slave loudspeaker boxes in the fault sub-loop is less than 2.

When the target loop includes 1 slave loudspeaker, for the content in S105, the embodiment of the present application further provides a possible implementation manner, and the slave loudspeaker in the target loop is determined as the fault node.

When the slave speakers in the total loop are arranged according to a predetermined sequence, on the basis of fig. 3, for the content in S103, the embodiment of the present application further provides a possible implementation manner, please refer to fig. 7, where S103 includes: s103-1 and S103-2.

S103-1, the main sound box intercepts a section of continuous auxiliary sound boxes from the main loop according to a set sequence to serve as target sound boxes in the target loop.

S103-2, the main sound box generates a first target transmission sequence corresponding to the target loop according to the target sound box.

For example, the target loop includes a slave enclosure a, a slave enclosure B, a slave enclosure C, and a slave enclosure D, where the slave enclosures are in the master loop in a predetermined order from enclosure a to enclosure B, and from enclosure C to enclosure D. The first target delivery sequence is from master enclosure to slave enclosure A to slave enclosure B, and from enclosure C to slave enclosure D to master enclosure. Namely, the first target transmission sequence is consistent with the arrangement of the slave loudspeaker boxes in the total loop according to the set sequence.

On the basis of fig. 3, regarding how to determine whether the total loop has a fault, the embodiment of the present application further provides a possible implementation manner, please refer to fig. 8, and the method for locating a fault in a sound box system further includes S101 and S102.

And S101, the main sound box sends a third detection frame in the main loop according to a preset period.

First detection frame, second detection frame and third detection frame in this application embodiment all carry corresponding sign to main audio amplifier discerns. For the sake of brevity, the description of the third sounding frame is not repeated here, and in particular, reference is made to the description of the first sounding frame.

And S102, under the condition that the main sound box does not receive the third detection frame returned by the total loop in the second time interval, the main sound box determines that the total loop has a fault.

Wherein the second time interval is greater than or equal to the preset period.

Optionally, the second time interval is 3 times the period, e.g. 30 ms.

In one possible implementation, the number of slave loudspeaker boxes is 2.

In a possible implementation manner, after the failure node is determined, the main speaker may perform an alarm, for example, send a failure prompt to the user terminal, where the failure prompt includes an identifier of the failure node; for example, the main sound box can prompt the user that a fault occurs through a fault prompting lamp; for example, the main speaker may perform a fault broadcast, and the broadcast content includes an identifier of the fault node, so as to remind a user to maintain the fault node.

Claims

1. A method for locating a fault of a sound box system is characterized in that the method is applied to a main sound box of the sound box system, the sound box system further comprises at least two slave sound boxes, the main sound box and the at least two slave sound boxes form a general loop in a wireless communication mode, and the method for locating the fault of the sound box system comprises the following steps:

2. The loudspeaker system fault location method of claim 1, wherein the method further comprises:

under the condition that the main sound box receives the first detection frame returned by the target loop in a first time interval, the main sound box generates a first target transmission sequence corresponding to a new target loop, wherein the new target loop comprises at least one new slave sound box relative to any historical target loop;

and the main sound box repeatedly sends the first detection frame in the target loop until the main sound box does not receive the first detection frame returned by the target loop in a first time interval.

3. The loudspeaker system fault localization method of claim 1 or 2, wherein when the target loop includes at least two slave loudspeakers, the step of the master loudspeaker locating the fault node from the target loop comprises:

the main sound box splits the target loop into at least two sub-loops;

the main sound box sequentially sends a second detection frame in each sub-loop till a fault sub-loop is determined, wherein the second detection frame comprises a second target transmission sequence corresponding to the sub-loop, and the fault sub-loop is a sub-loop of the main sound box which does not receive the second detection frame returned within a first time interval;

the master loudspeaker box judges whether the number of slave loudspeaker boxes in the fault sub-loop is greater than 2;

if not, determining the slave loudspeaker boxes in the fault sub-loop as fault nodes;

if so, splitting the fault sub-loop into at least two new sub-loops, and repeating the main loudspeaker box to sequentially send a second detection frame in each sub-loop until the fault sub-loop is determined.

4. The loudspeaker system fault localization method of claim 2, wherein the new target loop is not intersected with any historical target loop.

5. The method for locating a failure in an acoustic enclosure system of claim 1, wherein the slave acoustic enclosures in the master loop are arranged in a predetermined order, and the step of generating the first target transmission order corresponding to the target loop by the master acoustic enclosure when the master loop fails comprises:

the main sound box intercepts a section of continuous auxiliary sound boxes from the main loop according to the set sequence to serve as target sound boxes in the target loop;

and the main sound box generates a first target transmission sequence corresponding to the target loop according to the target sound box.

6. The loudspeaker system fault location method of claim 1, wherein prior to determining that the total loop is faulty, the method further comprises:

the main sound box sends a third detection frame in the main loop according to a preset period;

and under the condition that the main sound box does not receive the third detection frame returned by the total loop in a second time interval, the main sound box determines that the total loop has a fault, wherein the second time interval is greater than or equal to a preset period.

7. The loudspeaker system fault location method of claim 1, wherein the number of slave loudspeakers is 2.
