[0073] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0074] The information transmission method provided in this application embodiment can be applied to, for example... Figure 1 In the application environment shown, the transmitting end 102 communicates with the receiving end 104 via a network. A data storage system can store the data that the transmitting end 102 and the receiving end 104 need to process. The data storage system can be integrated into the transmitting end 102 and the receiving end 104, or it can be placed in the cloud or on other network servers. The transmitting end 102 modifies the original frequency characteristic values ​​of the original colored light signal through a first correspondence and a second correspondence to obtain a target colored light signal carrying the information to be transmitted, and sends the target colored light signal to the receiving end 104. The receiving end 104 extracts the information to be transmitted from the target colored light signal based on the first correspondence and the second correspondence. The transmitting end 102 and the receiving end 104 can be, but are not limited to, various personal communication devices, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can be smart speakers, smart TVs, smart air conditioners, smart vehicle devices, etc. Portable wearable devices can be smartwatches, smart bracelets, head-mounted devices, etc. The transmitting end 102 and the receiving end 104 can be implemented using independent servers or a server cluster composed of multiple servers.

[0075] In one embodiment, such as Figure 2 As shown, an information transmission method is provided, which is applied to...Figure 1 Taking the sender 102 as an example, the explanation includes the following steps:

[0076] Step 201: Based on the first correspondence between the type of information to be transmitted and the frequency of colored light, and the second correspondence between the content of the information to be transmitted and the frequency characteristic value, modify the original frequency characteristic value of the original colored light signal to obtain the target colored light signal carrying the information to be transmitted.

[0077] The first correspondence is used to represent the colored light frequencies corresponding to different types of information to be transmitted. Furthermore, since the colored light frequencies corresponding to the colored light signals are between 191.3 THz (Tera Hertz) and 196.1 THz, the first correspondence is specifically used to represent the colored light frequencies corresponding to different types of information to be transmitted between 191.3 THz and 196.1 THz.

[0078] The second correspondence is used to represent the frequency characteristic values ​​corresponding to the contents of different information to be transmitted. Furthermore, the frequency characteristic value of the colored light frequency can be represented by five-bit binary data. Therefore, the second correspondence is specifically used to determine the binary data identifiers corresponding to the contents of different information to be transmitted.

[0079] It should be noted that when it is necessary to modify the original frequency characteristic value of the original colored light signal, the target frequency to be modified can be determined from the colored light frequency of the original colored light signal according to the first correspondence; the target frequency characteristic value corresponding to the information to be transmitted can be determined according to the second correspondence, and then the original frequency characteristic value of the target frequency in the original colored light signal can be modified to the target frequency characteristic value.

[0080] The first and second correspondences can be determined based on the experience of the staff and the actual content of the information to be transmitted. They are fed back to the sending and receiving ends before the information transmission method is executed. The content of the first and second correspondences is not limited here.

[0081] To further explain, the target frequency includes an information-carrying field. Specifically, when it is necessary to modify the original frequency characteristic value of the original colored light signal, the original frequency characteristic value corresponding to the information-carrying field of the target frequency in the original colored light signal is modified to the target frequency characteristic value.

[0082] The information-carrying field in the target frequency is used to represent the feature field in the target frequency that carries the characteristics of the target frequency, and the information-carrying field in the target frequency can be located in any one or more positions in the target frequency.

[0083] For example, the frequency characteristic value of the target frequency A can be represented by five-bit binary data. The first and second frequency characteristic values ​​of the five-bit binary frequency characteristic value can be the information carrying field a of the target frequency A. Alternatively, the second, third, and fourth frequency characteristic values ​​of the five-bit binary frequency characteristic value can be the information carrying field a of the target frequency A.

[0084] To further clarify, the target frequency also includes a flag field, which can be located at any position within the target frequency. The binary value corresponding to the flag field indicates whether the target frequency contains the information to be transmitted.

[0085] Step 202: Send the target colored light signal to the receiving end to instruct the receiving end to extract the information to be transmitted from the target colored light signal based on the first correspondence and the second correspondence.

[0086] It should be noted that after modifying the original frequency characteristic values ​​of the original colored light signal, the frequency characteristic values ​​of the target colored light signal are mapped with the information to be transmitted. Then, after the target colored light signal is sent to the receiving end, the receiving end can extract the information to be transmitted from the target colored light signal.

[0087] To further explain, when the receiving end extracts the information to be transmitted, it may specifically include the following: determining the target frequency from the color light frequencies of the target color light signal according to the first correspondence; and determining the information to be transmitted corresponding to the target frequency feature value of the target frequency according to the second correspondence.

[0088] The aforementioned information transmission method modifies the original frequency characteristic values ​​of the original colored light signal through a first correspondence and a second correspondence, obtaining a target colored light signal carrying the information to be transmitted. Furthermore, by sending the target colored light signal to the receiving end, the receiving end extracts the information to be transmitted from the target colored light signal. Since the above process modifies the original frequency characteristic values ​​of the original colored light signal to transform it into a target colored light signal carrying the information to be transmitted, without generating an additional transmission message for the information to be transmitted, and by sending the target colored light signal to the receiving end, the information to be transmitted is transmitted along with the signal, eliminating the need for separate transmission of the information to be transmitted. Therefore, the transmission cost of sending the information to be transmitted is reduced, enabling the receiving end to extract the information to be transmitted from the target colored light signal according to the first and second correspondences, thereby completing the transmission operation of the information to be transmitted.

[0089] In one embodiment, the original frequency characteristic value of the original colored light signal can be modified according to a first correspondence between the type of information to be transmitted and the frequency of colored light, and a second correspondence between the content of the information to be transmitted and the frequency characteristic value, thereby obtaining a target colored light signal carrying the information to be transmitted. Figure 3 As shown, it includes the following steps:

[0090] Step 301: Determine the target frequency from the color light frequency of the original color light signal based on the first correspondence between the type of information to be transmitted and the color light frequency.

[0091] It should be noted that the first correspondence is used to represent the colored light frequencies corresponding to different types of information to be transmitted. Therefore, when it is necessary to determine the target frequency, the type of signal to be transmitted can be determined, and then the colored light frequency corresponding to that type can be determined according to the first correspondence. This colored light frequency is the target frequency.

[0092] In one embodiment of this application, since the colored light frequency corresponding to the colored light signal is between 191.3 THz and 196.1 THz, and the frequency characteristic value of the colored light frequency can be represented by five-bit binary data, only 32 frequencies between 191.3 THz and 196.1 THz can be used as target frequencies. Specifically, when it is necessary to determine the target frequency, the type of the signal to be transmitted is determined to be type B, and according to the content recorded in the first correspondence, the colored light frequency corresponding to type B is determined to be 191.3 THz. Therefore, the colored light frequency 191.3 THz is used as the target frequency.

[0093] To further clarify, to ensure the accuracy of the target frequency determination, before determining the target frequency based on the first correspondence, it is necessary to verify whether the version of the first correspondence is the version agreed upon between the sender and the receiver. Specifically, the sender can send the content of the first correspondence to be verified to the receiver, so that the receiver can compare the received first correspondence with its own stored first correspondence. If they are the same, it is determined that the version of the first correspondence sent by the sender is the version agreed upon with the receiver; otherwise, if they are different, it is determined that the version of the first correspondence sent by the sender is not the version agreed upon with the receiver. In this case, the receiver can send back the first correspondence stored by the receiver to the sender.

[0094] Step 302: Determine the target frequency feature value corresponding to the information to be transmitted based on the second correspondence between the content of the information to be transmitted and the frequency feature value.

[0095] It should be noted that the second correspondence is used to represent the frequency characteristic values ​​corresponding to the contents of different information to be transmitted. Therefore, when it is necessary to determine the target frequency characteristic value corresponding to the information to be transmitted, the binary data representation corresponding to the contents of the information to be transmitted can be determined according to the second correspondence. This binary data is the target frequency characteristic value corresponding to the information to be transmitted.

[0096] In one embodiment of this application, when it is necessary to determine the target frequency characteristic value corresponding to the information to be transmitted, specifically, if the content of the information to be transmitted has a load rate of 40%, and according to the content recorded in the second correspondence relationship, it can be known that: if the load rate is less than 20%, the target frequency characteristic value is 00; if the load rate is between 20% and 50%, the target frequency characteristic value is 01; if the load rate is between 50% and 80%, the target frequency characteristic value is 10; and if the load rate is greater than 80%, the target frequency characteristic value is 11. Therefore, the target frequency characteristic value corresponding to a load rate of 40% is determined to be 01, and thus, 01 is the target frequency characteristic value corresponding to the information to be transmitted.

[0097] To further clarify, to ensure the accuracy of the target frequency determination, before determining the target frequency based on the second correspondence, it is necessary to verify whether the version of the second correspondence is the version agreed upon between the sender and the receiver. Specifically, the sender can send the second correspondence to be verified to the receiver, so that the receiver can compare the received second correspondence with its own stored second correspondence. If they are the same, it is determined that the version of the second correspondence sent by the sender is the version agreed upon with the receiver; otherwise, if they are different, it is determined that the version of the second correspondence sent by the sender is not the version agreed upon with the receiver. In this case, the receiver can send back the second correspondence stored by the receiver to the sender.

[0098] Step 303: Modify the original frequency characteristic value of the original colored light signal according to the target frequency characteristic value and the target frequency to obtain the target colored light signal carrying the information to be transmitted.

[0099] It should be noted that when modifying the original frequency characteristic value of the original colored light signal, the following can be included: modifying the original frequency characteristic value corresponding to the target frequency in the original colored light signal to the target frequency characteristic value.

[0100] In one embodiment of this application, the target frequency characteristic value is determined to be 10100, and the target frequency is 191.3THz. When modifying the original frequency characteristic value of the original colored light signal, the original frequency characteristic value corresponding to 191.3THz can be modified to 10100, thereby completing the modification operation of the target frequency.

[0101] To further explain, the characteristic field of the target frequency includes an information carrying field. Therefore, when the original frequency characteristic value corresponding to the target frequency in the original colored light signal is modified to the target frequency characteristic value, the following can be included: determining the information carrying field from the characteristic field of the target frequency based on the third correspondence between the type of information to be transmitted and each characteristic field in the colored light frequency; and modifying the original frequency characteristic value corresponding to the information carrying field in the original colored light signal to the target frequency characteristic value.

[0102] The information-carrying field is used to represent the feature field in the target frequency that carries the characteristics of the target frequency. Furthermore, the information-carrying field in the target frequency can be located in any one or more positions within the target frequency.

[0103] To further explain, since the frequency characteristic value of the colored light frequency can be represented by five bits of binary data, the third correspondence, used to indicate the type of information to be transmitted, can be represented by one or more bits of binary data from the colored light frequency. The third correspondence can be determined according to a prior agreement between the sending and receiving ends; its content is not limited here.

[0104] To further explain, the target frequency feature field also includes a flag field. Therefore, when modifying the original frequency feature value of the original colored light signal, it is necessary to modify the flag feature value corresponding to the flag field in the original colored light signal.

[0105] The binary value corresponding to the flag field is used to indicate whether the target frequency contains the information to be transmitted. The flag field can be represented by one bit of binary data in the colored light frequency. For example, the flag field can be represented by the first bit of binary data in the colored light frequency.

[0106] In one embodiment of this application, if the flag feature value corresponding to a certain target frequency flag field is 1, it indicates that the target frequency contains information to be transmitted; if the flag feature value corresponding to a certain target frequency flag field is 0, it indicates that the target frequency does not contain information to be transmitted.

[0107] In one embodiment of this application, if the flag field is represented by the first binary data in the color light frequency, then after modifying the original frequency feature value corresponding to the information-carrying field in the original color light signal to the target frequency feature value, the flag field of the target frequency modified to the target frequency feature value is changed to 1, and the flag field of the color light frequency with the original frequency feature value that has not been modified is changed to 0.

[0108] In one embodiment of this application, if, according to the third correspondence, the type of the information M to be transmitted is represented by the second and third binary data in the colored light frequency, and the type of the information N to be transmitted is represented by the fourth and fifth binary data in the colored light frequency; therefore, the second and third binary data in the colored light frequency are the information carrying fields of the information M to be transmitted; the fourth and fifth binary data in the colored light frequency are the information carrying fields of the information N to be transmitted; and the target frequency characteristic value of the information M to be transmitted is 10, and the target frequency characteristic value of the information N to be transmitted is 11, therefore, when modifying the original frequency characteristic value of the original colored light signal, such as Figure 4 As shown, the information carrying field of the information to be transmitted M in the target frequency of the original colored light signal can be modified to 10, and the information carrying field of the information to be transmitted N in the target frequency of the original colored light signal can be modified to 11. Since the flag field is represented by the first bit of binary data in the colored light frequency, the flag field in the target frequency can be modified to 1, thereby obtaining the target colored light signal carrying the information to be transmitted.

[0109] The aforementioned information transmission method determines the target frequency through a first correspondence and the target frequency characteristic value through a second correspondence. This ensures that when the original frequency characteristic value of the original colored light signal is modified, the original frequency characteristic value of the target frequency in the original colored light signal can be modified to the target frequency characteristic value. This realizes the mapping of the information to be transmitted to the frequency characteristic value of the original colored light signal, thereby obtaining the target colored light signal carrying the information to be transmitted. This enables the information to be transmitted and the colored light signal to be transmitted together to the receiving end, eliminating the need to transmit the information to be transmitted separately and reducing the transmission cost of sending the information to be transmitted.

[0110] With the increasing demand for information transmission between devices, more and more devices need to transmit information with other devices. Therefore, generating additional transmission messages when transmitting optical signals and transmitting these messages separately leads to a significant increase in transmission costs. To solve the above problem, this embodiment can achieve the following: Figure 5 The method shown presents an information transmission method that is applied to... Figure 1 The receiving end 104 in the middle includes the following steps:

[0111] Step 501: Receive the target colored light signal carrying the information to be transmitted sent by the transmitting end.

[0112] The target colored light signal is obtained by modifying the original frequency characteristic value of the original colored light signal based on the first correspondence between the type of information to be transmitted and the frequency of colored light, and the second correspondence between the content of the information to be transmitted and the frequency characteristic value.

[0113] It should be noted that when receiving a target colored light signal carrying information to be transmitted sent by the receiving end, the target colored light signal carrying information to be transmitted sent by the receiving end can be received through the colored light interface of the router.

[0114] Step 502: Extract the information to be transmitted from the target colored light signal according to the first correspondence and the second correspondence.

[0115] It should be noted that when it is necessary to extract the information to be transmitted from the target colored light signal, the target frequency corresponding to the target frequency feature value can be determined according to the first correspondence; and the information to be transmitted can be determined from the target frequency feature value of the target frequency according to the second correspondence.

[0116] In one embodiment of this application, a filtering process can be performed in the first correspondence relationship to determine whether each color light frequency in the target color light signal contains information to be transmitted, and the color light frequency containing the information to be transmitted is taken as the target frequency; and, according to the second correspondence relationship, the target frequency feature value in the target frequency is compared and queried to determine the information to be transmitted corresponding to the target frequency feature value.

[0117] In the above information transmission method, the receiving end receives the target colored light signal and extracts the information to be transmitted from the target colored light signal according to the first correspondence and the second correspondence. Since the original frequency characteristic value of the original colored light signal is modified in the above process, the original colored light signal is modified into a target colored light signal carrying the information to be transmitted, and no additional transmission message of the information to be transmitted is generated. Furthermore, by sending the target colored light signal to the receiving end, the information to be transmitted is transmitted to the receiving end at the same time, without the need to transmit the information to be transmitted separately. Therefore, the transmission cost of sending the information to be transmitted is reduced, and the receiving end can extract the information to be transmitted from the target colored light signal according to the first correspondence and the second correspondence, thereby completing the transmission operation of the information to be transmitted.

[0118] In one embodiment, when extracting the information to be transmitted from the target colored light signal according to the first correspondence and the second correspondence, at this time, as follows: Figure 6 As shown, it specifically includes the following:

[0119] Step 601: Determine the target frequency from the color light frequencies of the target color light signal according to the first correspondence.

[0120] It should be noted that when it is necessary to determine the target frequency, the following may be included: determining the initial screening frequency from the color light frequency of the target color light signal based on the flag feature value corresponding to the flag field in the color light frequency of the target color light signal; and determining the target frequency from the initial screening frequency based on the first correspondence relationship.

[0121] If the flag feature value corresponding to a certain target frequency flag field is 1, it means that the target frequency contains information; if the flag feature value corresponding to a certain target frequency flag field is 0, it means that the target frequency does not contain information.

[0122] In one embodiment of this application, the flag feature value corresponding to the flag field in the color light frequency of the target color light signal is determined, and the color light frequency with a flag feature value of 1 is used as the initial screening frequency; according to the first correspondence, the target frequency containing the information to be transmitted from the initial screening frequency containing information is determined.

[0123] The initial screening frequency with a flag feature value of 1 can be the target frequency containing the information to be transmitted, or it can be a colored light frequency whose original frequency feature value in the flag field is 1. Therefore, the target frequency needs to be determined from the initial screening frequencies based on the first correspondence.

[0124] Step 602: Based on the second correspondence, determine the information to be transmitted corresponding to the target frequency feature value of the target frequency.

[0125] It should be noted that when it is necessary to determine the information to be transmitted, the specific steps may include the following: determining the information carrying field from the feature fields of the target frequency based on the third correspondence between the type of information to be transmitted and each feature field in the colored light frequency; extracting the target frequency feature value of the information carrying field of the target frequency; and determining the information to be transmitted corresponding to the target frequency feature value based on the second correspondence.

[0126] In one embodiment of this application, an information carrying field containing information to be transmitted is determined according to a third correspondence relationship, and then, the information to be transmitted corresponding to the target frequency feature value of the information carrying field is determined according to a second correspondence relationship.

[0127] For example, if the second and third binary data bits in the target frequency are determined to be information carrying fields according to the third correspondence relationship; if the target frequency characteristic value corresponding to the second and third binary data bits is 11, then according to the second correspondence relationship, the information to be transmitted corresponding to the target frequency characteristic value of the information carrying field being 11 is found.

[0128] The above information transmission method, based on the first and second correspondence relationships, extracts the information to be transmitted from the target colored light signal, ensuring that the receiving end can determine the information to be transmitted based on the target colored light signal carrying the information to be transmitted sent by the sending end; thus achieving low-cost information transmission between the receiving end and the sending end.

[0129] In one embodiment, the transmitting end and the receiving end complete the transmission process of the target colored light signal and the information to be transmitted as follows: Figure 7As shown, it may specifically include the following:

[0130] Step 701: The transmitting end determines the target frequency from the color light frequency of the original color light signal based on the first correspondence between the type of information to be transmitted and the color light frequency.

[0131] Step 702: The transmitting end determines the target frequency feature value corresponding to the information to be transmitted based on the second correspondence between the content of the information to be transmitted and the frequency feature value.

[0132] Step 703: The transmitting end determines the information carrying field from the feature fields of the target frequency based on the third correspondence between the type of information to be transmitted and each feature field in the colored light frequency.

[0133] Step 704: The transmitting end modifies the original frequency feature value corresponding to the information-carrying field in the original colored light signal to the target frequency feature value.

[0134] Step 705: The transmitting end modifies the flag feature value corresponding to the flag field in the original colored light signal.

[0135] Step 706: The transmitting end sends the target colored light signal to the receiving end.

[0136] Step 707: The receiving end receives the target colored light signal carrying the information to be transmitted sent by the sending end.

[0137] Step 708: The receiving end determines the initial screening frequency from the color light frequency of the target color light signal based on the flag feature value corresponding to the flag field in the color light frequency of the target color light signal.

[0138] Step 709: The receiving end determines the target frequency from the initially screened frequencies based on the first correspondence.

[0139] Step 710: The receiving end determines the information carrying field from the feature fields of the target frequency based on the third correspondence between the type of information to be transmitted and each feature field in the colored light frequency.

[0140] Step 711: The receiving end extracts the target frequency feature value from the information carrying field of the target frequency.

[0141] Step 712: The receiving end determines the information to be transmitted corresponding to the target frequency feature value according to the second correspondence relationship.

[0143]

[0144] In one embodiment of this application, the colored light frequencies of the target colored light signal sent from the transmitting end to the receiving end, from 191.3THz to 196.1THz, can be used as 32 colored light frequencies of the target frequency, as well as the frequency characteristic values ​​corresponding to the 32 colored light frequencies. The receiving end can determine the information to be transmitted based on the colored light frequencies shown in Table 1 above and the frequency characteristic values ​​of the colored light frequencies.

[0145] The aforementioned information transmission method modifies the original frequency characteristic values ​​of the original colored light signal through a first correspondence and a second correspondence, obtaining a target colored light signal carrying the information to be transmitted. Furthermore, by sending the target colored light signal to the receiving end, the receiving end extracts the information to be transmitted from the target colored light signal. Since the above process modifies the original frequency characteristic values ​​of the original colored light signal to transform it into a target colored light signal carrying the information to be transmitted, without generating an additional transmission message for the information to be transmitted, and by sending the target colored light signal to the receiving end, the information to be transmitted is transmitted along with the signal, eliminating the need for separate transmission of the information to be transmitted. Therefore, the transmission cost of sending the information to be transmitted is reduced, enabling the receiving end to extract the information to be transmitted from the target colored light signal according to the first and second correspondences, thereby completing the transmission operation of the information to be transmitted.
