Description

Technical Field

[0001] The present invention relates to the technical field of smart rods, and more specifically, to a method for adjusting volume of a smart rod and a smart rod. Background Art

[0002] With the development of smart devices, smart poles can be seen everywhere on the road. The sound column devices on smart poles can play advertisements, music, warning information, etc. at any time, or provide information notifications in emergencies, providing a new way to obtain information and bringing great convenience to people's daily lives.

[0003] Existing sound column equipment always plays information at the same volume, which can cause problems such as the sound being too loud when the distance is too close or the content being unclear when the distance is too far. In addition, the warning broadcast played at the same volume for a long time in dangerous locations can easily make people relax their vigilance, ignore the danger, and fail to achieve the expected warning effect. In order to solve the above problems, the sound column volume can only be adjusted manually online or offline, and the volume cannot be reasonably controlled according to the distance in real time.

[0004] In the prior art, the utility model patent with authorization announcement number CN202309920U discloses a television that can automatically adjust the volume according to human activities, including an infrared sensor 101, which is used to detect the distance between the user and the television in real time and send it to a television volume control unit 103; a volume off distance setting unit 102, which is used to pre-set and store the volume off working distance of the television; the television volume control unit 103 is connected to the infrared sensor 101 and the volume off distance setting unit 102, respectively, and is used to compare the distance between the user and the television detected by the infrared sensor 101 and the television volume off working distance stored by the volume off distance setting unit 102 in real time. When the distance between the user and the television is greater than or equal to the television volume off working distance and the duration reaches a predetermined time length, the television is controlled to perform a mute operation, and when the distance between the user and the television is less than the television volume off working distance, the current volume of the television is kept unchanged. However, this method can only provide a suggestion for adjusting the volume of the sound column device when the distance between the pedestrian and the sound column device is greater than or equal to the preset distance, but it is still impossible to calculate the reasonable volume according to the distance between the pedestrian and the smart pole in real time to control the volume of the sound column device.

[0005] Therefore, the present invention provides a method for adjusting volume using a smart rod and a smart rod. Summary of the invention

[0049] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0052] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0053] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0054] Example 1

[0055] Combination Figure 1 , Figure 1 1 is a flow chart of a method for adjusting volume by a smart rod provided by the present invention, to illustrate a specific embodiment of the method for adjusting volume by a smart rod provided by the present invention, including:

[0056] S101: The client provides basic parameters and configures the basic parameters into the sound column controller. The basic parameters include intelligent volume adjustment switch, default playback volume, maximum preset distance, maximum preset distance volume and minimum preset volume;

[0057] S102: The radar obtains the distance between the pedestrian within the detection range of the radar and the radar in real time, including: obtaining a vector pointing from the center point of the pedestrian within the detection range of the radar to the center point of the radar, and taking the length of the orthographic projection of the vector on the ground as the distance between the pedestrian and the radar;

[0058] S103: The radar forms a data group of the current moment with the distances between all pedestrians and the radar acquired at the current moment and transmits the data group to the sound column controller in real time;

[0059] S104: After receiving the current moment data group, the sound column controller determines whether the intelligent volume adjustment switch is turned on;

[0060] S1051: If the intelligent volume adjustment switch is turned on, determine whether the current data set is an empty set;

[0061] S1052: If the intelligent volume adjustment switch is off, the sound column controller controls the sound column to play at the default playback volume.

[0062] S1061: If the current data set is not an empty set, extract the minimum value in the current data set as the current minimum distance, and determine whether the current minimum distance is greater than the maximum preset distance;

[0063] S1062: If the data set at the current moment is an empty set, the sound column controller controls the sound column to play at a default playback volume.

[0064] S1071: If the current minimum distance is less than or equal to the maximum preset distance, the current volume is calculated according to the current minimum distance, the maximum preset distance, the maximum preset distance volume and the minimum preset volume, and the calculation is performed in the following manner:

[0065] Current volume = (current minimum distance / maximum preset distance) × (maximum preset distance volume - minimum preset volume) + minimum preset volume;

[0066] The sound column controller controls the sound column to play at the current volume.

[0067] S1072: If the current minimum distance is greater than the maximum preset distance, the sound column controller controls the sound column to play at a default playback volume.

[0068] It should be noted that the maximum preset distance volume refers to the volume corresponding to the time when the distance between the pedestrian and the radar is equal to the maximum preset distance; the minimum preset volume refers to the volume corresponding to the time when the center point of the pedestrian overlaps with the center point of the radar in the direction perpendicular to the ground; the units of the default playback volume, maximum preset distance volume and minimum preset volume are %, and the units of the maximum preset distance and the current minimum distance are meters. Of course, this is not limited to this and can also be adjusted according to actual conditions.

[0069] It can be understood that if the data group at the current moment is not an empty set, there are pedestrians passing within the detection range of the radar, and it is necessary to further determine whether the current minimum distance is greater than the maximum preset distance. If the current minimum distance is less than or equal to the maximum preset distance, the volume of the sound column is adjusted according to the current minimum distance, so that the volume of the sound column changes with the change of the distance between the pedestrian and the radar. If the current minimum distance is greater than the maximum preset distance or the data group at the current moment is an empty set, it means that the distance between the pedestrian and the smart pole is too far or there are no pedestrians passing within the detection range of the radar. The content played by the sound column has little effect on pedestrians, so there is no need to adjust the volume of the sound column. When the data group at the current moment is an empty set, or the current minimum distance is greater than the maximum preset distance, the sound column controller controls the sound column to play at the default playback volume. If the default playback volume is set to 0 at this time, that is, when the distance between the person and the smart pole is too far or no one passes near the smart pole, the sound column does not play, and it can also reduce the use of electricity and achieve energy saving.

[0070] Compared with the prior art, the method for adjusting the volume of the smart pole provided in the present embodiment, when the smart volume adjustment switch is turned on, the data group at the current moment is not an empty set and the current minimum distance is less than or equal to the maximum preset distance, calculates the current volume according to (current minimum distance / maximum preset distance)×(maximum preset distance volume-minimum preset volume)+minimum preset volume, and the sound column controller controls the sound column to play at the current volume. It can calculate a reasonable volume according to the distance between the pedestrian and the radar in real time to control the volume of the sound column, without manual participation in adjusting the volume of the sound column, thus saving labor costs, and this volume adjustment method does not need to be implemented based on the network. In the absence of a network or a poor network, the sound column volume can be intelligently adjusted to improve the sound column playback effect. If the default playback volume is set to 0, energy saving can also be achieved and power consumption can be reduced.

[0071] Example 2

[0072] Combination Figure 2 and Figure 3 , Figure 2 is another flow chart of the method for adjusting volume by a smart rod provided by the present invention. Figure 3 1 is another flow chart of the method for adjusting volume by a smart rod provided by the present invention, to illustrate another specific embodiment of the method for adjusting volume by a smart rod provided by the present invention, including:

[0073] Reference Figure 2 , write basic parameters to the sound column controller through the client. The basic parameters include intelligent volume adjustment switch, default playback volume, maximum preset distance, maximum preset distance volume and minimum preset volume.

[0074] The radar monitors the distance between pedestrians and itself in real time and feeds back the information to the sound column controller. The distance between pedestrians and the radar reflects the distance between pedestrians and the sound column.

[0075] After receiving the distance information between the pedestrian and the radar, the sound column controller calculates the volume according to the basic parameters, or calculates the volume according to the basic parameters and the distance information between the pedestrian and the radar.

[0076] The sound column is played at the calculated volume.

[0077] It should be noted that the orthographic projection of the radar's detection range on the ground is a circle with the center point of the radar as the center and a preset length as the radius. The maximum preset distance is less than the preset length. Since the radar's ranging results for pedestrians at the edge of its detection range may have errors, the maximum preset distance is further set to be less than 80% × the preset length to avoid erroneous judgments due to erroneous data.

[0078] Specifically, the volume is calculated based on the basic parameters, or the volume is calculated based on the basic parameters and the distance information between the pedestrian and the radar. Figure 3 ,include:

[0079] When the intelligent volume adjustment switch is off, the sound column volume is the default playback volume.

[0080] When the intelligent volume adjustment switch is on, it is determined whether the distance between the pedestrian and the radar is greater than the maximum preset distance or no one is passing by. Here, it can be determined whether no one is passing by first, and then whether the distance between the pedestrian and the radar is greater than the maximum preset distance. It can also be determined whether no one is passing by and whether the distance between the pedestrian and the radar is greater than the maximum preset distance at the same time. It is not limited to this. Here, the distance between the pedestrian and the radar refers to the minimum value of the distance between the pedestrian and the radar at the current moment, which can also be called the current minimum distance.

[0081] When the distance between the pedestrian and the radar is greater than the maximum preset distance or no one is passing by, the sound column volume is the default playback volume.

[0082] When the distance between the pedestrian and the radar is less than or equal to the maximum preset distance, the current volume is calculated based on the distance between the pedestrian and the radar and the basic parameters. The current volume = (current minimum distance / maximum preset distance) × (maximum preset distance volume - minimum preset volume) + minimum preset volume.

[0083] Based on this, the method for adjusting the volume of the smart pole provided in this embodiment can not only ensure that the sound column always plays at the default playback volume, but also calculate the reasonable volume in real time according to the distance between the pedestrian and the radar to control the volume of the sound column.

[0084] According to Table 1, the smaller the distance between the pedestrian and the radar, the smaller the volume of the sound column is adjusted, as follows:

[0085] Set the intelligent volume adjustment switch to on, the default playback volume to 0%, the maximum preset distance to 50 meters, the maximum preset distance volume to 80% and the minimum preset volume to 5%. Of course, the settings of basic parameters are not limited to this and can be set according to actual conditions.

[0086] According to the distance between the pedestrian and the radar and the basic parameters, the volume change table of the sound column can be calculated, as shown in Table 1:

[0087] Table 1. Sound column volume change table

[0088] Current minimum distance / meter Calculation method volume / % 0 (0 / 50)×(80-5)+5 5 5 (5 / 50)×(80-5)+5 12.5 10 (10 / 50)×(80-5)+5 20 15 (15 / 50)×(80-5)+5 27.5 20 (20 / 50)×(80-5)+5 35 25 (25 / 50)×(80-5)+5 42.5 30 (30 / 50)×(80-5)+5 50 35 (35 / 50)×(80-5)+5 57.5 40 (40 / 50)×(80-5)+5 65 45 (45 / 50)×(80-5)+5 72.5 50 (50 / 50)×(80-5)+5 80 55 Beyond the maximum preset distance: default playback volume 0 60 Beyond the maximum preset distance: default playback volume 0 No one passed by No one passing by: Default playback volume 0

[0089] It is understandable that the smaller the distance between a person and the radar, the smaller the volume of the sound column, which can improve the pedestrian's auditory comfort. Moreover, when the distance between the pedestrian and the radar exceeds the maximum preset distance and no one passes within the radar detection range, the volume of the sound column is 0, which can also achieve energy-saving effects.

[0090] According to Table 2, the smaller the distance between the pedestrian and the radar, the louder the volume of the sound column is adjusted, as follows:

[0091] Set the intelligent volume adjustment switch to on, the default playback volume to 0%, the maximum preset distance to 50 meters, the maximum preset distance volume to 5% and the minimum preset volume to 80%. Of course, the settings of basic parameters are not limited to this and can be set according to actual conditions.

[0092] According to the distance between the pedestrian and the radar and the basic parameters, the volume change table of the sound column can be calculated, as shown in Table 2:

[0093] Table 2. Sound column volume change table

[0094] Current minimum distance / meter Calculation method volume / % 0 (0 / 50)×(5-80)+80 80 5 (5 / 50)×(5-80)+80 72.5 10 (10 / 50)×(5-80)+80 65 15 (15 / 50)×(5-80)+80 57.5 20 (20 / 50)×(5-80)+80 50 25 (25 / 50)×(5-80)+80 42.5 30 (30 / 50)×(5-80)+80 35 35 (35 / 50)×(5-80)+80 27.5 40 (40 / 50)×(5-80)+80 20 45 (45 / 50)×(5-80)+80 12.5 50 (50 / 50)×(5-80)+80 5 55 Beyond the maximum preset distance: default playback volume 0 60 Beyond the maximum preset distance: default playback volume 0 No one passed by No one passing by: Default playback volume 0

[0095] It is understandable that the smaller the distance between a person and the radar, the louder the volume of the sound column can enhance the warning effect on pedestrians. Moreover, when the distance between the pedestrian and the radar exceeds the maximum preset distance and no one passes within the radar detection range, the volume of the sound column is 0, which can also achieve energy-saving effects.

[0096] Of course, if the sound column playback volume remains unchanged, and there is no need to calculate the reasonable volume according to the distance between the pedestrian and the radar in real time to control the volume of the sound column, you only need to set the intelligent volume adjustment switch to off so that the sound column always plays at the default playback volume, refer to Table 3:

[0097] Table 3. Sound column volume change table

[0098] Current minimum distance / meter Calculation method volume / % 0 Smart volume adjustment switch off: default playback volume 80 5 Smart volume adjustment switch off: default playback volume 80 10 Smart volume adjustment switch off: default playback volume 80 15 Smart volume adjustment switch off: default playback volume 80 20 Smart volume adjustment switch off: default playback volume 80

[0099] Table 3. Sound column volume change table

[0100] Current minimum distance / meter Calculation method volume / % 25 Smart volume adjustment switch off: default playback volume 80 30 Smart volume adjustment switch off: default playback volume 80 35 Smart volume adjustment switch off: default playback volume 80 40 Smart volume adjustment switch off: default playback volume 80 45 Smart volume adjustment switch off: default playback volume 80 50 Smart volume adjustment switch off: default playback volume 80 55 Smart volume adjustment switch off: default playback volume 80 60 Smart volume adjustment switch off: default playback volume 80 No one passed by Smart volume adjustment switch off: default playback volume 80

[0101] Therefore, the method for adjusting the volume using a smart rod provided in this embodiment can adjust the volume of the sound column more flexibly.

[0102] Example 3

[0103] Combination Figure 4 , Figure 4 A structural diagram of a smart rod provided by the present invention is provided to illustrate a specific embodiment of the smart rod provided by the present invention, and a method for adjusting the volume of the smart rod provided by the above embodiment includes:

[0104] Rod body 5;

[0105] The sound column 4 is fixed on the surface of the rod body 5;

[0106] Radar 3, fixed on the side of the sound column 4 close to the ground;

[0107] The sound column controller 2 is fixed on the surface of the rod body 5; the sound column controller 2 is respectively connected to the sound column 4 and the radar 3;

[0108] The sound column controller 2 is configured with basic parameters, including an intelligent volume adjustment switch, a default playback volume, a maximum preset distance, a maximum preset distance volume, and a minimum preset volume. The sound column controller 2 is used to determine whether the intelligent volume adjustment switch is turned on after the sound column controller 2 receives the current moment data group transmitted by the radar 3;

[0109] If the intelligent volume adjustment switch is turned on, determine whether the current data set is an empty set;

[0110] If the intelligent volume adjustment switch is off, the sound column controller 2 controls the sound column 4 to play at the default playback volume;

[0111] If the current data set is not an empty set, extract the minimum value in the current data set as the current minimum distance, and determine whether the current minimum distance is greater than the maximum preset distance;

[0112] If the data set at the current moment is an empty set, the sound column controller 2 controls the sound column 4 to play at the default playback volume;

[0113] If the current minimum distance is less than or equal to the maximum preset distance, the current volume is calculated based on the current minimum distance, the maximum preset distance, the maximum preset distance volume, and the minimum preset volume in the following manner:

[0114] Current volume = (current minimum distance / maximum preset distance) × (maximum preset distance volume - minimum preset volume) + minimum preset volume;

[0115] The sound column controller 2 controls the sound column 4 to play at the current volume;

[0116] If the current minimum distance is greater than the maximum preset distance, the sound column controller 2 controls the sound column 4 to play at the default playback volume.

[0117] Compared with the prior art, the smart pole provided in the present embodiment calculates the current volume according to the current minimum distance, the maximum preset distance, the maximum preset distance volume and the minimum preset volume when the intelligent volume adjustment switch is turned on, the data group at the current moment is not an empty set and the current minimum distance is less than or equal to the maximum preset distance. The sound column controller 2 controls the sound column 4 to play at the current volume, and can calculate a reasonable volume according to the distance between the pedestrian and the radar 3 in real time to control the volume of the sound column 4. There is no need for manual participation in adjusting the volume of the sound column 4, thus saving labor costs. Moreover, this volume adjustment method does not need to be implemented based on the network. In the absence of a network or a poor network, the volume of the sound column 4 can be intelligently adjusted to improve the playback effect of the sound column 4.

[0136] It is understandable that when the client 1 configures the basic parameters to the sound column controller 2, the client 1 and the sound column controller 2 can be wired to achieve data transmission, or the client 1 and the sound column controller 2 can be wirelessly connected to achieve data transmission, which can be set according to actual needs. After the basic parameters are configured to the sound column controller 2, the sound column controller 2 can operate according to the basic parameters, and the operation process does not require network participation, so that it can operate offline. When the intelligent volume adjustment switch is turned on, the data group at the current moment is not an empty set, and the current minimum distance is less than or equal to the maximum preset distance, the current volume is calculated based on the current minimum distance, the maximum preset distance, the maximum preset distance volume and the minimum preset volume. The sound column controller 2 controls the sound column 4 to play at the current volume, and can calculate a reasonable volume in real time according to the distance between the pedestrian and the radar 3 to control the volume of the sound column 4.

[0137] It can be seen from the above embodiments that the method for adjusting volume by a smart rod and the smart rod provided by the present invention at least achieve the following beneficial effects:

[0138] The method for adjusting the volume of a smart pole and the smart pole provided by the present invention, when the smart volume adjustment switch is turned on, the data group at the current moment is not an empty set and the current minimum distance is less than or equal to the maximum preset distance, calculates the current volume according to (current minimum distance / maximum preset distance)×(maximum preset distance volume-minimum preset volume)+minimum preset volume, and the sound column controller controls the sound column to play at the current volume. It can calculate a reasonable volume according to the distance between the pedestrian and the radar in real time to control the volume of the sound column, without manual participation in adjusting the volume of the sound column, saving labor costs, and this volume adjustment method does not need to be implemented based on the network. In the case of no network or poor network, the sound column volume can be intelligently adjusted to improve the sound column playback effect.

It will be appreciated by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
