Technical Field

[0001] The present application relates to the field of sound source protection, and in particular to a multi-sound source protection method and device. Background Art

[0002] With the continuous development of audio technology, people's ways of acquiring and enjoying music are becoming increasingly diverse. Multi-source playback through CD players can meet users' needs for different types and styles of music. Stable CD players can maintain signal continuity and accuracy when reading and playing CDs, thereby reducing distortion caused by mechanical vibration, electromagnetic interference and other factors, and improving users' listening experience.

[0003] At present, the stability of CD players is mainly achieved through dual-link backup, namely digital network backup and analog 100V backup, which is strictly dependent on the network environment and power supply. When the network environment is unstable or the power supply fails, the stability of the CD player will be affected. In addition, if there is a problem with one of the CD players, the stable playback of the audio source cannot be guaranteed.

[0004] Application Contents

[0029] The second processing module is used to issue an alarm through the server if it is confirmed that the calibration signal sent by any one or all of the CD players has not been received.

[0030] In the embodiment of the present application, a host receives a plurality of pairing codes sent by a plurality of the CD players, and establishes connections with the plurality of CD players based on the pairing codes. Thus, a connection can be established between the CD players and the host, so as to subsequently receive signals sent from the CD players.

If a CD player fails, the stable playback of the audio source cannot be guaranteed.

[0054] Embodiment 1

[0055] Please refer to Figure 1 , Figure 1 It is a structural schematic diagram of an embodiment of a multi-sound source protection device provided by the present application, the multi-sound source protection device includes a host, a server, at least one speaker and at least one CD player;

[0056] It can be understood that when there is only one CD player, the CD player can read the CD inserted by the user, and after successful reading, the audio signal is transmitted to the hearing host through wireless communication technology. When the host receives the correct audio signal, it will play the audio signal through the speaker. When the host does not receive the audio signal transmitted by the CD player, it will transmit the alarm information to the server through the network to alarm. When there are two CD players, you can first press the pairing button on the two CD players. At this time, the CD player will send the distribution code to the surrounding through wireless communication technology to establish a communication connection between the CD players. When the connection is successful, when one of the CD players is played, the play operation will also be transmitted to the other CD player through wireless communication technology, and the other CD player will also perform the corresponding play operation synchronously. Then the two CD players will transmit the audio signal to be played to the host through wireless transmission technology. When the host receives the audio signal sent by the two CD players, it will play the audio signal obtained from the two CD players through the speaker. When the host does not receive the audio signal transmitted by the CD player, it will transmit the alarm information to the server to alarm.

[0057] It should be noted that the number of CD players in this application can be two or more, and this application does not limit the number of CD players.

[0058] Embodiment 2

[0059] Please refer to Figure 2 , Figure 2 It is a flow chart of an embodiment of a multi-sound source protection method provided by the present application. The multi-sound source protection method is applicable to a multi-sound source protection device. The multi-sound source protection method includes steps S1 to S3;

[0060] Step S1, receiving a plurality of pairing codes sent by a plurality of the CD players, and establishing communication connections with a plurality of the CD players based on the plurality of the pairing codes;

[0061] It can be understood that before several CD players establish a communication connection with the host, it is necessary to first establish a communication connection between the several CD players. Specifically, it is necessary to turn on the pairing button between the first CD player and the second CD player. After the pairing button is turned on, the first CD player sends a first pairing code within the coverage range, wherein the first pairing code includes a first device name and a first identification code; when the second CD player receives the first pairing code sent by the first CD player, it will determine whether the first identification code corresponding to the first CD player exists in the second CD player. If the first identification code corresponding to the first CD player exists in the second CD player, the second CD player establishes a communication connection with the first CD player through wireless communication technology. When the CD players are successfully paired, all button commands will be synchronized. When the user presses the play button on the first CD player, the first CD player will transmit the play command to the second CD player through wireless communication technology. After receiving the play command, the second CD player will synchronously execute the play operation, so that the operations of the first CD player and the second CD player can be kept synchronized. Exemplarily, the first pairing code sent by the first CD player includes CD1-AA110, where CD1 corresponds to the device name of the first CD player, and AA110 corresponds to the identification code of the CD player. When the second CD player receives the first pairing code, it will send the identification code AA110 to the information processing module in the second CD player for CD player identification code verification. When AA110 exists in the information processing module of the second CD player, it means that the first CD player and the second CD player belong to the same type of CD player. Then the second CD player will send a communication connection request to the device name CD1 in front of the identification code AA110, and a communication connection can be established between the first CD player and the second CD player. When AA110 does not exist in the information processing module of the second CD player, it means that the first CD player and the second CD player do not belong to the same type of CD player. Then the second CD player will not send a communication connection request to the first CD player. When there are three or more CD players, the communication connection is also carried out in the same way, which will not be repeated here.

[0062] It should be noted that the identification code will first be set and stored in the CD player. When it is confirmed that the received identification code exists in the CD player, it is confirmed that it is a CD player of the same type. The device name corresponding to the received identification code can be used to confirm which CD player sent the pairing code.

[0063] It should be noted that the wireless communication technology may be infrared, Bluetooth, etc. As long as the technology can establish a connection and communicate, it falls within the protection scope of this application.

[0064] In this way, by establishing a communication connection between the first CD player and the second CD player, it is convenient to subsequently transmit instructions and synchronize operation instructions between the first CD player and the second CD player, thereby facilitating the simultaneous sending of signals to the host.

[0065] After establishing a communication connection between several CD players, it is necessary to establish a communication connection with the host. The method of establishing a communication connection between CD players is similar. It is also necessary to first set and store the identification code of the CD player in the host. When the host receives the pairing codes sent by several CD players, it will also determine whether the identification codes corresponding to the several CD players exist in the host. If the identification codes corresponding to the several CD players exist in the host, the host will establish a communication connection with the several CD players through wireless communication technology. Exemplarily, when the first pairing code sent by the first CD player includes CD1-AA110, and the second pairing code sent by the second CD player includes CD2-AA110, wherein CD1 and CD2 correspond to the device names of the first CD player and the second CD player respectively, and AA110 corresponds to the identification code of the CD player, when the host receives CD1-AA110 and CD2-AA110, the identification code AA110 will be sent to the host information processing module in the host for CD player identification code verification. When AA110 exists in the host information processing module, the host sends a communication connection request to CD1 and CD2 with the identification code AA110, and a communication connection can be established with several CD players. When AA110 does not exist in the host information processing module, the host will not send a communication connection request to CD1 and CD2.

[0066] It should be noted that the wireless communication technology may be infrared, Bluetooth, etc. As long as the technology can establish a connection and communicate, it falls within the protection scope of this application.

[0067] In this way, by establishing a communication connection between the CD player and the host, it is convenient for the subsequent host to receive the signal sent from the CD player and play the audio transmitted by the CD player.

[0068] It is understandable that after the CD player sends the pairing code, the waiting time for connection is limited. If the first CD player does not establish a communication connection with the second CD player or the host within the first preset time of sending the first pairing code, the first pairing code will be stopped. Exemplarily, if the communication connection is not established with other CD players or hosts for more than a preset time, such as 300 seconds, the pairing button will be directly turned off.

[0069] In this way, when the CD player does not establish a communication connection with other CD players or a host within a preset time, the wireless communication of the CD player is promptly shut down, thereby saving power consumption of the CD player.

[0070] It is understandable that after the communication connection is established between the CD players and between the CD players and the host, the CD players can read the optical disc put into the CD players by the user. If several of the CD players read successfully, the audio signal and the proofreading signal are sent to the host through the wireless communication technology; if any of the CD players fails to read successfully within the second preset time, an alarm is issued through the server. Exemplarily, when the user puts the optical disc into the first CD player and the second CD player respectively, the first CD player and the second CD player can read the inserted optical disc at the same time. If the first CD player reads successfully first, the first CD player will enter the standby mode and wait for the second CD player to read successfully. When the second CD player also reads successfully, the second CD player will also enter the standby mode. When the play button is pressed in the first CD player or the second CD player, the first CD player and the second CD player will simultaneously send the audio signal and the proofreading signal to the host through the wireless communication technology, and the host will play the audio read from the first CD player and the second CD player through the speaker. The audio signals sent by all the CD players can be played simultaneously or in sequence according to the connection establishment time. The specific playing method can be preset. Similarly, if the second CD player reads successfully first, it also needs to wait for the first CD player to read successfully before subsequent operations can be performed. If the second CD player fails to read successfully after the first CD player has read successfully, and the preset waiting time has exceeded, then it is determined that the second CD player has a fault and the host has not received the audio signal, then an alarm will be issued through the server, so that the server can notify the staff to handle the second CD player.

[0071] In this way, by judging whether the CD player succeeds or fails in reading the optical disk, the abnormal CD player can be accurately identified and an alarm can be issued to facilitate subsequent maintenance of the abnormal CD player.

[0072] Step S2: if it is confirmed that the calibration signals sent by all the CD players are received, the audio signals sent by all the CD players are played through the host;

[0073] It can be understood that when the host receives the proofreading signal, it will send the proofreading signal to the host information processing module to determine whether the proofreading signals sent by all the CD players are received, wherein the proofreading signal is detected by the signal detection module in each CD player to detect the change in the audio line voltage and determine whether there is audio output. If it is confirmed that the proofreading signals sent by all the CD players are received, the audio signals sent by all the CD players are played through the host; wherein the playing of the audio signals sent by all the CD players can be played simultaneously or in sequence according to the time of establishing the connection, and the specific playing method can be preset.

[0074] Step S3: If it is confirmed that the calibration signal sent by any one or all of the CD players has not been received, an alarm is issued through the server.

[0075] It is understandable that when the host information processing module determines that it has not received the proofreading signal sent by any of the CD players, the host will disconnect the connection with the CD player that has not received the signal, and at the same time play the audio signal of the CD player that has received the proofreading code, and send an alarm through the server to notify the staff through the server to process the CD player that has not received the proofreading signal. Exemplarily, when the proofreading signal of the first CD player is received, but the proofreading signal of the second CD player is not received, the connection with the first CD player is disconnected, and the audio signal sent by the second CD player is selected to be played, and the staff is notified through the server to process the first CD player. Similarly, when the proofreading signal of the first CD player is not received, but the proofreading signal of the second CD player is received, the operation of the host is the same, which will not be repeated here.

[0076] When the host information processing module determines that it has not received the proofreading signals sent by all the CD players, it means that several CD players have failed. On the one hand, an alarm will be issued through the server to notify the staff to handle the several CD players. At the same time, because the host has no audio to play, the host will also alarm through the buzzer to remind the staff to handle it.

[0077] In the embodiment of the present application, a host receives a plurality of pairing codes sent by a plurality of the CD players, and establishes connections with the plurality of CD players based on the pairing codes. Thus, a connection can be established between the CD players and the host, so as to subsequently receive signals sent from the CD players. By confirming whether a calibration signal from the CD player is received, it can be determined whether there is an audio signal output from the CD player, and then the current state of the CD player can be accurately determined. According to the current state of the CD player, corresponding playback or alarm operations can be performed to ensure the stability of multi-source playback.

[0078] Embodiment 3

[0079] Please refer to Figure 3 , Figure 3 It is a structural diagram of another embodiment of a multi-sound source protection device provided by the present application; a receiving module 01, a first processing module 02 and a second processing module 03;

[0080] The receiving module 01 is used to receive a plurality of pairing codes sent by a plurality of the CD players, and establish a communication connection with the plurality of the CD players based on the plurality of the pairing codes;

[0081] It can be understood that before several CD players establish a communication connection with the host, it is necessary to first establish a communication connection between the several CD players. Specifically, it is necessary to turn on the pairing button between the first CD player and the second CD player. After the pairing button is turned on, the first CD player sends a first pairing code within the coverage range, wherein the first pairing code includes a first device name and a first identification code; when the second CD player receives the first pairing code sent by the first CD player, it will determine whether the first identification code corresponding to the first CD player exists in the second CD player. If the first identification code corresponding to the first CD player exists in the second CD player, the second CD player establishes a communication connection with the first CD player through wireless communication technology. When the CD players are successfully paired, all button commands will be synchronized. When the user presses the play button on the first CD player, the first CD player will transmit the play command to the second CD player through wireless communication technology. After receiving the play command, the second CD player will synchronously execute the play operation, so that the operations of the first CD player and the second CD player can be kept synchronized. Exemplarily, the first pairing code sent by the first CD player includes CD1-AA110, where CD1 corresponds to the device name of the first CD player, and AA110 corresponds to the identification code of the CD player. When the second CD player receives the first pairing code, it will send the identification code AA110 to the information processing module in the second CD player for CD player identification code verification. When AA110 exists in the information processing module of the second CD player, it means that the first CD player and the second CD player belong to the same type of CD player. Then the second CD player will send a communication connection request to the device name CD1 in front of the identification code AA110, and a communication connection can be established between the first CD player and the second CD player. When AA110 does not exist in the information processing module of the second CD player, it means that the first CD player and the second CD player do not belong to the same type of CD player. Then the second CD player will not send a communication connection request to the first CD player. When there are three or more CD players, the communication connection is also carried out in the same way, which will not be repeated here.

[0082] It should be noted that the identification code will first be set and stored in the CD player. When it is confirmed that the received identification code exists in the CD player, it is confirmed that it is a CD player of the same type. The device name corresponding to the received identification code can be used to confirm which CD player sent the pairing code.

[0083] It should be noted that the wireless communication technology may be infrared, Bluetooth, etc. As long as the technology can establish a connection and communicate, it falls within the protection scope of this application.

[0084] In this way, by establishing a communication connection between the first CD player and the second CD player, it is convenient to subsequently transmit instructions and synchronize operation instructions between the first CD player and the second CD player, thereby facilitating the simultaneous sending of signals to the host.

[0085] Specifically, the receiving module includes: a sending unit and a connecting unit; the sending unit is used for the host to receive a number of the pairing codes sent by a number of the CD players within the coverage area, wherein the pairing code includes a device name and an identification code; the connecting unit is used for if the number of the identification codes corresponding to the number of the CD players exist in the host, then the host establishes a communication connection with the number of the CD players through wireless communication technology.

[0086] After establishing a communication connection between several CD players, it is necessary to establish a communication connection with the host. The method of establishing a communication connection between CD players is similar. It is also necessary to first set and store the identification code of the CD player in the host. When the host receives the pairing codes sent by several CD players, it will also determine whether the identification codes corresponding to the several CD players exist in the host. If the identification codes corresponding to the several CD players exist in the host, the host will establish a communication connection with the several CD players through wireless communication technology. Exemplarily, when the first pairing code sent by the first CD player includes CD1-AA110, and the second pairing code sent by the second CD player includes CD2-AA110, wherein CD1 and CD2 correspond to the device names of the first CD player and the second CD player respectively, and AA110 corresponds to the identification code of the CD player, when the host receives CD1-AA110 and CD2-AA110, the identification code AA110 will be sent to the host information processing module in the host for CD player identification code verification. When AA110 exists in the host information processing module, the host sends a communication connection request to CD1 and CD2 with the identification code AA110, and a communication connection can be established with several CD players. When AA110 does not exist in the host information processing module, the host will not send a communication connection request to CD1 and CD2.

[0087] It should be noted that the wireless communication technology may be infrared, Bluetooth, etc. As long as the technology can establish a connection and communicate, it falls within the protection scope of this application.

[0088] In this way, by establishing a communication connection between the CD player and the host, it is convenient for the subsequent host to receive the signal sent from the CD player and play the audio transmitted by the CD player.

[0089] Specifically, the multi-sound source guarantee device also includes: a stop module; the stop module is used to stop sending the first pairing code if the first CD player does not establish a communication connection with the second CD player or the host within a first preset time of sending the first pairing code.

[0090] It is understandable that after the CD player sends the pairing code, the waiting time for connection is limited. If the first CD player does not establish a communication connection with the second CD player or the host within the first preset time of sending the first pairing code, the first pairing code will be stopped. Exemplarily, if the communication connection is not established with other CD players or hosts for more than a preset time, such as 300 seconds, the pairing button will be directly turned off.

[0091] In this way, when the CD player does not establish a communication connection with other CD players or a host within a preset time, the wireless communication of the CD player is promptly shut down, thereby saving power consumption of the CD player.

[0092] Specifically, the multi-sound source guarantee device also includes a judgment module; the judgment module includes: a reading unit and a judgment unit; the reading unit is used for several of the CD players to read the inserted optical discs respectively; the judgment unit is used to send the audio signal and the proofreading signal to the host through wireless communication technology if several of the CD players have successfully read; if any of the CD players fails to read successfully within the second preset time, an alarm is issued through the server.

[0093] It is understandable that after the communication connection is established between the CD players and between the CD players and the host, the CD players can read the optical disc put into the CD players by the user. If several of the CD players read successfully, the audio signal and the proofreading signal are sent to the host through the wireless communication technology; if any of the CD players fails to read successfully within the second preset time, an alarm is issued through the server. Exemplarily, when the user puts the optical disc into the first CD player and the second CD player respectively, the first CD player and the second CD player can read the inserted optical disc at the same time. If the first CD player reads successfully first, the first CD player will enter the standby mode and wait for the second CD player to read successfully. When the second CD player also reads successfully, the second CD player will also enter the standby mode. When the play button is pressed in the first CD player or the second CD player, the first CD player and the second CD player will simultaneously send the audio signal and the proofreading signal to the host through the wireless communication technology, and the host will play the audio read from the first CD player and the second CD player through the speaker. The audio signals sent by all the CD players can be played simultaneously or in sequence according to the connection establishment time. The specific playing method can be preset. Similarly, if the second CD player reads successfully first, it also needs to wait for the first CD player to read successfully before subsequent operations can be performed. If the second CD player fails to read successfully after the first CD player has read successfully, and the preset waiting time has exceeded, then it is determined that the second CD player has a fault and the host has not received the audio signal, then an alarm will be issued through the server, so that the server can notify the staff to handle the second CD player.

[0094] In this way, by judging whether the CD player succeeds or fails in reading the optical disk, the abnormal CD player can be accurately identified and an alarm can be issued to facilitate subsequent maintenance of the abnormal CD player.

[0095] The first processing module 02 is used for playing the audio signals sent by all the CD players through the host if it is confirmed that the proofreading signals sent by all the CD players have been received;

[0096] It can be understood that when the host receives the proofreading signal, it will send the proofreading signal to the host information processing module to determine whether the proofreading signals sent by all the CD players are received, wherein the proofreading signal is detected by the signal detection module in each CD player to detect the change in the audio line voltage and determine whether there is audio output. If it is confirmed that the proofreading signals sent by all the CD players are received, the audio signals sent by all the CD players are played through the host; wherein the playing of the audio signals sent by all the CD players can be played simultaneously or in sequence according to the time of establishing the connection, and the specific playing method can be preset.

[0097] The second processing module 03 is used to issue an alarm through the server if it is confirmed that the calibration signal sent by any one or all of the CD players has not been received.

[0098] It is understandable that when the host information processing module determines that it has not received the proofreading signal sent by any of the CD players, the host will disconnect the connection with the CD player that has not received the signal, and at the same time play the audio signal of the CD player that has received the proofreading code, and send an alarm through the server to notify the staff through the server to process the CD player that has not received the proofreading signal. Exemplarily, when the proofreading signal of the first CD player is received, but the proofreading signal of the second CD player is not received, the connection with the first CD player is disconnected, and the audio signal sent by the second CD player is selected to be played, and the staff is notified through the server to process the first CD player. Similarly, when the proofreading signal of the first CD player is not received, but the proofreading signal of the second CD player is received, the operation of the host is the same, which will not be repeated here.

[0099] When the host information processing module determines that it has not received the proofreading signals sent by all the CD players, it means that several CD players have failed. On the one hand, an alarm will be issued through the server to notify the staff to handle the several CD players. At the same time, because the host has no audio to play, the host will also alarm through the buzzer to remind the staff to handle it.

[0100] In the embodiment of the present application, a host receives a plurality of pairing codes sent by a plurality of the CD players, and establishes connections with the plurality of CD players based on the pairing codes. Thus, a connection can be established between the CD players and the host, so as to subsequently receive signals sent from the CD players. By confirming whether a calibration signal from the CD player is received, it can be determined whether there is an audio signal output from the CD player, and then the current state of the CD player can be accurately determined. According to the current state of the CD player, corresponding playback or alarm operations can be performed to ensure the stability of multi-source playback.

[0101] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present application. It should be understood that the above description is only a specific embodiment of the present application and is not intended to limit the scope of protection of the present application. It is particularly pointed out that for those skilled in the art, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of protection of the present application.
