[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figs. 1-2The application is a remote control-based charging outdoor Bluetooth sound system, which comprises a sound body 1, a trailing rod 2 fixedly connected to the rear surface of the sound body 1, a moving wheel 3 symmetrically and rotatably connected to the inside of the lower surface of the sound body 1 near one end of the trailing rod 2, a charging port 4 formed in one side of the sound body 1, and a positioning pad 5 fixedly connected to the lower surface of the sound body 1 away from the moving wheel 3. The trailing rod 2 is used to move the sound body 1, and the charging port 4 is used to charge other electrical equipment, thereby achieving the charging effect.

[0036] The inside of the sound body 1 is provided with a remote control box, which is provided with a pairing management module, a remote control evaluation module, a progressive analysis module, a remote control difficulty analysis module, a playing supervision module, and an intelligent management module.

[0037] The pairing management module is used to collect the pairing state information of the control end and the target sound, and analyze the pairing control state of the pairing state information, so as to understand the pairing situation of the target sound, and to realize the control of the target sound. The specific pairing control state analysis process is as follows:

[0038] The sound body 1 is set as the target sound, the pairing state information of the control end and the target sound is obtained, the pairing state information includes pairing success and pairing failure, and after the pairing state information is discriminated and processed:

[0039] If the pairing state information of the control end and the target sound is pairing success, a control signal is generated;

[0040] If the pairing state information of the control end and the target sound is pairing failure, an unauthorized signal is generated, and after the unauthorized signal is generated, the target sound is paired again;

[0041] When the control signal is generated, the remote control evaluation module is used to respond to the control signal, collect the straight-line distance between the control end and the target sound, and analyze the remote control disconnection risk of the straight-line distance. The specific remote control disconnection risk analysis process is as follows:

[0042] The connection control period of the target sound is collected and set as a time threshold, the straight-line distance between the control end and the target sound within the time threshold is obtained, and the standard basic information between the control end and the target sound within the time threshold is obtained. The standard basic information represents the farthest straight-line control distance of the target sound. The straight-line distance and the standard basic information are compared and analyzed:

[0043] If the straight-line distance is less than the standard basic information, a feedback signal is generated;

[0044] If the straight line distance is greater than or equal to the standard basic information, a disconnection warning signal is generated, and the disconnection warning signal is sent to the intelligent management module. After receiving the disconnection warning signal, the intelligent management module immediately makes a preset warning operation corresponding to the disconnection warning signal, so as to remind the operator of the control end to reasonably control the distance, so as to ensure the stability and smoothness of the target sound control;

[0045] When the feedback signal is generated, the progressive analysis module is used to collect control interference information in the control area in response to the feedback signal, and to perform control risk quantitative division analysis on the control interference information, so as to further analyze whether the target sound remote control exists a disconnection risk from the perspective of control interference. The specific control risk quantitative division analysis process is as follows:

[0046] The control area is set as the area obtained by drawing a circle around the target sound as the center and the straight line distance as the radius. The control interference information in the control area within the time threshold is obtained, and the control interference information includes the physical interference index and the non-physical interference value.

[0047] The total number of physical interference information existing in the control area is obtained and is set as the physical interference index. The physical interference information includes display screens, metal doors and windows, etc.

[0048] The sum value between the total number of same frequency signal sources in the control area and the value corresponding to the number of environmental interference information exceeding the preset threshold after data normalization processing is obtained. The environmental interference information includes temperature, electromagnetic intensity, etc.

[0049] The physical interference index and the non-physical interference value are compared and analyzed with the preset physical interference index threshold and the preset non-physical interference value threshold. The number corresponding to the physical interference index and the non-physical interference value greater than or equal to the preset physical interference index threshold and the preset non-physical interference value threshold is set as the control risk coefficient, and the control risk coefficient is discriminated:

[0050] If the control risk coefficient = 0, a first-level remote control signal is generated;

[0051] If the control risk coefficient = 1, a second-level remote control signal is generated;

[0052] If the control risk coefficient is 2, a three-level remote control signal is generated, wherein the remote abnormal risk corresponding to the first-level remote control signal, the second-level remote control signal and the third-level remote control signal increases in turn, the first-level remote control signal, the second-level remote control signal and the third-level remote control signal are set as remote control risk levels YK, YK = 1, 2, 3, that is, the remote control risk level YK = 1 indicates the first-level remote control signal, the remote control risk level YK = 2 indicates the second-level remote control signal, and the remote control risk level YK = 3 indicates the third-level remote control signal. The remote control risk level YK is sent to the intelligent management module. After receiving the remote control risk level YK, the intelligent management module immediately performs a preset warning operation corresponding to the remote control risk level YK, so as to remind the control end to select a reasonable position according to the remote control risk level YK of the current target sound, so as to ensure the signal strength of the target sound and avoid the target sound from being disconnected.

[0053] In the second embodiment, when the control signal is generated, the remote control difficulty analysis module is used to respond to the control signal and collect the parameter information of the target sound, and the parameter information is subjected to control difficulty evaluation and quantitative analysis, that is, the analysis is performed from two aspects of parameters and response, so as to understand the remote control difficulty of the current target sound. The specific control difficulty evaluation and quantitative analysis process is as follows:

[0054] The parameter information of the target sound within the time threshold is obtained, the parameter information includes energy consumption, operating temperature, etc. The number of values of the parameter information exceeding the preset threshold is obtained. The number of values of the parameter information exceeding the preset threshold is set as a playback evaluation index. It should be noted that the greater the value of the playback evaluation index, the greater the normal control risk of the target sound.

[0055] The response evaluation value of the target sound within the time threshold is obtained. The response evaluation value represents the proportion of the number of normal responses of the target sound in the total number of instructions sent by the target sound. It should be noted that the response evaluation value is an influencing parameter reflecting the control stability of the target sound.

[0056] The playback evaluation index and the response evaluation value of the target sound are obtained. The playback evaluation index and the response evaluation value are labeled as BC and XC respectively. The playback evaluation index BC and the response evaluation value XC are substituted into the formula N = [BC x a1 ÷ (XC x a2)] x a3 to obtain a control difficulty evaluation coefficient, wherein a1 and a2 are preset weight factor coefficients of the playback evaluation index BC and the response evaluation value XC respectively, and a3 is a preset error correction factor. a1, a2 and a3 are all greater than zero, and N is the control difficulty evaluation coefficient.

[0057] When the control signal is generated, the play supervision module is used to respond to the control signal, and the control characteristic information of the target sound is collected, and the safety play supervision feedback analysis is carried out on the control characteristic information, that is, the control risk analysis is carried out from the current play and regulation, so as to understand the control precision risk of the target sound, and the specific safety play supervision feedback analysis process is as follows:

[0058] The number of times of playing card in the time threshold and the total duration of the card are obtained, and the product value obtained by multiplying the number of times of playing card and the total duration of the card is set as the playing performance coefficient, it should be pointed out that the playing performance coefficient is an influence parameter reflecting the control stability of the target sound;

[0059] The control characteristic information of the target sound in the time threshold is obtained, the control characteristic information includes volume up, volume down, next song, etc., the parameter in the control characteristic information is set as g, g is a natural number greater than zero, the number of times that the actual operation in the control characteristic information is inconsistent with the set operation is obtained, and the number is set as the control deviation value, it should be pointed out that the greater the value of the control deviation value, the greater the risk of accurate control of the target sound, wherein the actual operation is inconsistent with the set operation, for example, the actual operation is volume up, and the set operation is not volume up;

[0060] In the embodiment of the application, when g=1, it means volume up, when g=2, it means volume down, when g=3, it means next song, and so on;

[0061] The playing performance coefficient and the control deviation value are compared and analyzed with the preset playing performance coefficient threshold and the preset control deviation value threshold, and the number of the playing performance coefficient and the control deviation value greater than or equal to the preset playing performance coefficient threshold and the preset control deviation value threshold is set as the playing control evaluation coefficient;

[0062] The control difficulty evaluation coefficient N and the playing control evaluation coefficient are compared and analyzed with the preset control difficulty evaluation coefficient threshold and the preset playing control evaluation coefficient threshold:

[0063] If the control difficulty evaluation coefficient N is less than the preset control difficulty evaluation coefficient threshold, and the playing control evaluation coefficient=0, a continuous control signal is generated;

[0064] If the control difficulty evaluation coefficient N is greater than or equal to the preset control difficulty evaluation coefficient threshold, or the playback control evaluation coefficient ≠ 0, a control risk signal is generated, and the continuous control signal or the control risk signal is sent to the intelligent management module. After receiving the continuous control signal or the control risk signal, the intelligent management module immediately makes the preset warning operation corresponding to the continuous control signal or the control risk signal, so as to reasonably manage the target sound, which on the one hand helps to improve the operation and play supervision efficiency of the target sound, and facilitates timely targeted management of the target sound, and on the other hand helps to improve the continuous stability control effect of the target sound.

[0065] As shown above, from the perspective of preliminary remote control analysis, the pairing of the target sound is understood in order to control the target sound. Through information feedback, the control distance and control difficulty are analyzed from two points to ensure the continuous stability control effect of the target sound, that is, the remote control distance is analyzed in order to remind the operator of the control end to control the distance reasonably, and further analyze whether the target sound remote control exists a disconnection risk from the perspective of control interference in order to reasonably plan the control distance and ensure the signal strength of the target sound to avoid disconnection of the target sound.

[0066] From the control difficulty, the state performance and play regulation performance of the target sound are comprehensively analyzed, which on the one hand helps to improve the operation control supervision efficiency of the target sound, and facilitates timely targeted management of the target sound, and on the other hand helps to improve the continuous stability control effect of the target sound.

[0067] The size of the threshold is set for easy comparison. The size of the threshold depends on the number of sample data and the base number set by the person skilled in the art for each group of sample data. As long as it does not affect the proportional relationship between the parameters and the quantized values.

[0068] The size of the coefficient is to obtain a specific value by quantizing each parameter for subsequent comparison. The size of the coefficient depends on the number of sample data and the preliminary operation coefficient set by the person skilled in the art for each group of sample data. As long as it does not affect the proportional relationship between the parameters and the quantized values.

[0069] The above formulas are obtained by collecting a large amount of data and selecting a formula close to the true value. The coefficients in the formula are set by the person skilled in the art according to the actual situation. The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical scheme and inventive concept of the present application, makes equivalent replacement or change, which should be covered within the protection scope of the present application.
