Description

Technical Field

[0001] The present invention relates to the technical field of network data transmission, and in particular to a data transmission method and system for Internet of Things devices and computer equipment. Background Art

[0002] The data transmission method of IoT devices is not only low-power, but also highly reliable, and is widely used in fields that require real-time monitoring and rapid response. There are usually multiple IoT devices in a local area network. The data of IoT devices is transmitted to the control center through the transmission hub in the local area network. The control center generates feedback data based on the data of each IoT device, and the feedback data can be transmitted to the IoT device through the transmission hub. The distribution of transmission paths in the local area network is complex. In order to ensure the accuracy and efficiency of data transmission in the local area network, it is necessary to reasonably set the transmission storage space capacity of each type of data transmitted in the local area network.

[0003] In the existing method, the transmission storage space capacity of different types of data in the local area network is the same and fixed. For example, the minimum transmission storage space capacity of each type of data is set to the transmission storage space capacity of each type of data in the local area network. This may cause the data transmission storage space capacity to be too small, affecting the efficiency of data transmission in the local area network, and thus causing data transmission chaos; or the maximum transmission storage space capacity of each type of data is set to the transmission storage space capacity of each type of data in the local area network. This may cause the data transmission storage space capacity to be too large, resulting in a waste of resources; making it impossible to reasonably set the corresponding data transmission storage space capacity according to the actual situation of the various data to be transmitted, which is not conducive to the stable and efficient transmission of data in the local area network.

In addition, specific features, structures or characteristics in one or more embodiments may be combined in any suitable form.

[0055] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0056] The following is a detailed description of a data transmission method, system and computer device for an Internet of Things device provided by the present invention in conjunction with the accompanying drawings.

[0057] Embodiment 1:

[0058] The specific scenario of this embodiment is as follows: For better description, this embodiment assumes that there are only three types of devices in a local area network, namely, IoT devices, transmission hubs, and control hubs. Among them, there is only one control hub, and the number of IoT devices and transmission hubs is unlimited. IoT devices and control hubs can be directly connected, or the IoT devices and control hubs can be indirectly connected through the transmission hub. In this embodiment, the connection between the IoT device and the transmission hub, the connection between the IoT device and the control hub, the connection between the transmission hub and the transmission hub, and the connection between the transmission hub and the control hub are all used as transmission paths. All transmission paths and all devices in the local area network are jointly constructed to form the overall structure of the local area network. In order to ensure the stability of the network environment of the local area network, all devices in the local area network are synchronized through the NTP (Network Time Protocol) server, and then parameters are configured according to the needs of different devices, such as data transmission frequency, data format, transmission protocol and other parameters.

[0059] The purpose of this embodiment is: in order to accurately and efficiently transmit various data in the local area network, this embodiment obtains the transmission importance of each transmission path according to the location distribution of the transmission path in the local area network and the data transmitted by the transmission path, and then determines the importance of each transmission hub in the local area network for data transmission according to the transmission importance of the transmission path connected to each transmission hub. In order to analyze the transmission of each type of data in the local area network and ensure the stable and efficient transmission of each type of data in the local area network, this embodiment further analyzes the duration of each type of data transmitted by each transmission hub to determine the importance of each type of data in each transmission hub. The transmission weight of each data transmitted by each transmission hub is obtained according to the transmission importance of the transmission path connected to each transmission hub and the transmission duration of each data transmitted by each transmission hub within the second preset time period, and the transmission status of each data in each transmission hub is determined. Then, according to the transmission weight of each data in different transmission hubs, the preset minimum transmission storage space capacity of each data is accurately adjusted to obtain the target transmission storage space capacity of each data, thereby improving the efficiency of data transmission in the local area network, avoiding the situation where a large amount of data is not transmitted in time and causing data transmission chaos, and ensuring accurate and efficient transmission of data in the local area network.

[0060] This embodiment proposes a data transmission method for an IoT device. Figure 1 , which shows a schematic flow chart of a data transmission method of an Internet of Things device provided by an embodiment of the present invention, the method comprising the following steps:

[0061] Step S1: Acquire each transmission path for data transmission in the local area network.

[0062] Specifically, in order to ensure that each type of data in the LAN is transmitted stably and efficiently, it is necessary to analyze the transmission status of each type of data in the LAN, and then reasonably adjust the transmission storage space capacity of each type of data. In order to accurately analyze the transmission status of each type of data in the LAN, it is necessary to first obtain each transmission path for data transmission in the LAN. By analyzing each transmission path, it is conducive to the subsequent accurate analysis of data transmission status.

[0063] Step S2: according to the position distribution of each transmission path in the local area network and the data transmission situation of each transmission path in the first preset time period, the transmission importance of each transmission path is obtained.

[0064] It is known that the distribution of transmission paths in a local area network is intricate. When a certain transmission path is farther away from the IoT device in the transmission structure, it means that the data passing through the transmission path may be more, which indirectly means that the transmission path has a greater impact on the overall structure of the local area network, and the transmission path is more important in the data transmission process. At the same time, when the transmission path is closer to the control center in the transmission structure, it indirectly means that the transmission path is in an important position in the overall structure of the local area network, ensuring that the data transmission in the local area network is not interrupted, which also means that the transmission path is more important in the data transmission process. On the other hand, when the data transmitted by a certain transmission path is more stable, it means that the result analyzed by the transmission path is more accurate. Furthermore, this embodiment obtains the transmission importance of each transmission path according to the position distribution of each transmission path in the local area network and the situation of each transmission path transmitting data within the first preset time period. The greater the transmission importance, the greater the role of the corresponding transmission path in transmitting data in the local area network, and the more important the corresponding transmission path is in the data transmission process.

[0065] Preferably, in one possible implementation of this embodiment, the method for obtaining the transmission importance is as follows: Figure 2 , which shows a flow chart of a method for obtaining transmission importance provided by this embodiment, the method comprising the following steps:

[0066] Step S201: Acquire the structural influence degree of each transmission path according to the position distribution of each transmission path in the local area network.

[0067] The more transmission paths a transmission path has with IoT devices in the overall structure of a local area network, the more important the transmission path is in the data transmission process, and the more important the transmission path is in the overall structure of the local area network. At the same time, the closer the transmission path is to the control center, that is, the fewer transmission paths there are between the transmission path and the control center, it indirectly reflects that the transmission path is more important in the overall structure of the local area network. Furthermore, this embodiment obtains the structural influence of each transmission path based on the position distribution of each transmission path in the local area network.

[0068] Preferably, in a method that can be implemented in this embodiment, the method for obtaining the degree of structural influence is: for any transmission path, obtain the local path corresponding to the Internet of Things device to the transmission path, and use the local path that does not include the control center as the reference path; wherein, the reference path includes the transmission path; it should be noted that there are some Internet of Things devices whose data is not transmitted through the transmission path, and this embodiment defaults that there is no reference path between these Internet of Things devices and the transmission path. In order to analyze the position distribution of the transmission path in the local area network, the maximum number of them is obtained based on the number of transmission paths passed by each reference path, wherein the reference path corresponding to the maximum number is the longest reference path. The larger the maximum number, the more important the position of the transmission path in the local area network structure, and the more important the transmission path is in the process of transmitting data; in order to more accurately analyze the structural influence of the local area network of the transmission path, the number of transmission paths corresponding to the shortest path between the transmission path and the control center is further obtained as the second number; the smaller the second number, the more core the position of the transmission path in the local area network, and the more important the transmission path is in the process of transmitting data. Then, according to the maximum number and the second number, the structural influence degree of the transmission path is obtained; wherein the maximum number and the structural influence degree are positively correlated; and the second number and the structural influence degree are negatively correlated.

[0069] In order to accurately represent the importance of each transmission path in the overall structure of the local area network, this embodiment specifically quantifies the structural influence degree as a structural influence degree value. The larger the structural influence degree value, the more important the corresponding transmission path is in the process of transmitting data. The calculation formula of the structural influence degree value is: ; In the formula, is the structural influence value of the i-th transmission path; is the maximum number corresponding to the i-th transmission path; is the second quantity corresponding to the i-th transmission path; is the first preset positive integer.

[0070] This embodiment will Set to 1 to avoid the denominator being 0. Implementers can set it according to actual conditions. The size is not limited here.

[0071] At this point, the structural influence value of each transmission path is obtained.

[0072] Step S202: Acquire the transmission stability of each transmission path according to the data transmission condition of each transmission path within the first preset time period.

[0073] The more stable the data transmitted in a certain transmission path is, the more accurate the analysis result of the transmission data corresponding to the transmission path is. Therefore, this embodiment obtains the transmission stability of each transmission path according to the data transmission situation of each transmission path in the first preset time period, and corrects the structural influence of each transmission path according to the transmission stability, so as to accurately analyze the importance of each transmission path in the data transmission process. The greater the transmission stability, the more stable the data transmitted by the corresponding transmission path, and the more accurate the analysis result of the corresponding transmission path. This embodiment sets the first preset time period to 8 hours. The implementer can set the size of the first preset time period according to the actual situation, which is not limited here. Among them, the purpose of setting the first preset time period is to more accurately and efficiently analyze the changes in the data transmitted by each transmission path.

[0074] Preferably, in a method that can be implemented in this embodiment, the method for obtaining the transmission stability is: determine a moment at each interval of a preset time length within the first preset time period, and all of them are used as the target moment; in this embodiment, the preset time length is set to 10 minutes, and the implementer can set the size of the preset time length according to the actual situation, which is not limited here. Among them, the purpose of setting the target moment is to more efficiently analyze the situation of the data transmitted by each transmission path within the first preset time period. For any transmission path, the amount of data of each type of data transmitted by the transmission path at each target moment is obtained, and a vector is constructed as the data transmission vector of the transmission path at the corresponding target moment, accurately reflecting the situation of the data transmission of the transmission path at each target moment; in order to analyze the stability of the data transmitted by the transmission path within the first preset time period, the cosine similarity of the data transmission vectors at any two adjacent target moments is obtained, and all are used as the transmission data similarity value; the larger the transmission data similarity value, the more similar the data transmitted by the transmission path between the corresponding two adjacent target moments; in order to reflect the stability of the data transmitted by the transmission path, the average of all transmission data similarity values ​​is used as the transmission stability of the transmission path. The greater the transmission stability, the more stable the data transmitted by the transmission path.

[0075] At this point, the transmission stability of each transmission path is obtained.

[0076] Step S203: acquiring the transmission importance of each transmission path according to the structural influence degree and the transmission stability degree of each transmission path; wherein the structural influence degree and the transmission stability degree are both positively correlated with the transmission importance degree.

[0077] It is known that the greater the degree of structural influence, the more important the corresponding transmission path is in the entire local area network; the greater the degree of transmission stability, the more stable the data transmitted by the corresponding transmission path, which indirectly reflects that the data transmission situation reflected by the corresponding transmission path is more accurate, and the result of the analysis of the transmission path is accurate. Furthermore, this embodiment accurately obtains the transmission importance of each transmission path according to the degree of structural influence and the degree of transmission stability of each transmission path; wherein the degree of structural influence and the degree of transmission stability are both positively correlated with the degree of transmission importance. The greater the degree of transmission importance, the more important the data transmitted by the corresponding transmission path is.

[0078] In order to accurately indicate the importance of data transmission on each transmission path, this embodiment specifically quantifies the transmission importance as a transmission importance value. The larger the transmission importance value, the more important the data transmission on the corresponding transmission path is. The calculation formula of the transmission importance value is: ; In the formula, is the transmission importance value of the i-th transmission path; is the structural influence value of the i-th transmission path; is the transmission stability of the i-th transmission path. right Make corrections so that It more accurately reflects the importance of the i-th transmission path in the local area network.

[0079] At this point, the transmission importance value of each transmission path is obtained.

[0080] Step S3: Obtain the transmission weight of each data transmitted by each transmission hub according to the transmission importance of the transmission path connected to each transmission hub and the transmission duration of each data transmitted by each transmission hub within the second preset time period.

[0081] Specifically, after the data of the IoT device is transmitted to the transmission hub through the transmission path, it is then transmitted from the transmission hub to the next transmission hub or control hub to ensure that the data of the IoT device eventually reaches the control hub. In order to ensure that each type of data can be transmitted stably and efficiently in different transmission hubs, it is necessary to reasonably set the size of the transmission storage space of each type of data during the transmission process. It can be seen from step S2 that the transmission importance of each transmission path can indirectly reflect the importance of the data transmitted by each transmission path, wherein the data transmitted by the transmission path connected to each transmission hub will pass through the corresponding transmission hub. In order to determine the situation of the data transmitted by each transmission hub, firstly according to the transmission importance of the transmission path connected to each transmission hub, the importance of the data transmitted by each transmission hub is analyzed. In order to further analyze the transmission situation of each type of data transmitted by each transmission hub, then according to the duration of each transmission hub transmitting each type of data, the proportion of each type of data transmitted by each transmission hub is determined, and the transmission situation of each type of data in each transmission hub is determined. Furthermore, this embodiment obtains the transmission weight of each type of data transmitted by each transmission hub according to the transmission importance of the transmission path connected to each transmission hub and the transmission duration of each type of data transmitted by each transmission hub within the second preset time period, accurately reflecting the transmission of the corresponding type of data in the corresponding transmission hub. Among them, the greater the transmission weight, the greater the proportion of the corresponding type of data transmitted in the corresponding transmission hub. In order to ensure the stable and efficient transmission of the corresponding type of data, the transmission storage space capacity of the corresponding type of data should be larger.

[0082] Preferably, in one possible implementation of this embodiment, the method for obtaining the transmission weight is as follows: Figure 3 , which shows a flow chart of a method for obtaining a transmission weight provided in this embodiment, the method comprising the following steps:

[0083] Step S301: Obtain the transmission demand level of each transmission hub according to the transmission importance of the transmission path connected to each transmission hub.

[0084] When the transmission importance of the transmission paths connected to a certain transmission hub is greater, the more important the transmission hub is in the local area network, and the greater the transmission demand of the transmission hub. Therefore, this embodiment obtains the transmission demand of each transmission hub according to the transmission importance of the transmission paths connected to each transmission hub. The greater the transmission demand, the more important the corresponding transmission hub is in the process of data transmission.

[0085] In one possible implementation of this embodiment, the method for obtaining the transmission demand degree is: for any transmission hub, the transmission importance values ​​of all transmission paths connected to the transmission hub are accumulated and normalized, and the result is used as the transmission demand degree of the transmission hub. Among them, this embodiment uses the norm normalization function to normalize the result of accumulating the transmission importance values ​​of all transmission paths connected to the transmission hub.

[0086] At this point, the transmission demand level of each transmission hub is obtained.

[0087] Step S302: According to the transmission duration of each type of data transmitted by each transmission hub within the second preset time period, obtain the transmission duration ratio of each type of data transmitted by each transmission hub.

[0088] For any transmission hub, all data transmitted by the transmission paths connected to the transmission hub will pass through the transmission hub. In order to ensure that different types of data are transmitted stably and efficiently in the transmission hub, it is necessary to analyze the transmission status of each type of data transmitted by the transmission hub in the transmission hub. The longer the time it takes for a certain type of data transmitted by the transmission hub to be transmitted in the transmission hub, the greater the proportion of the data transmitted in the transmission hub. In order to improve the efficiency of the transmission hub in transmitting the data, the transmission storage space capacity of the data should be larger. Furthermore, this embodiment obtains the transmission time ratio of each type of data transmitted by each transmission hub according to the transmission time of each type of data transmitted by each transmission hub within the second preset time period. The greater the transmission time ratio, the greater the proportion of the corresponding type of data transmitted in the corresponding transmission hub.

[0089] In one way that can be implemented in this embodiment, the method for obtaining the transmission time ratio is: for any transmission hub and any type of data transmitted by the transmission hub within the second preset time period, obtain the total time for the transmission hub to transmit the data within the second preset time period as the target time for the transmission hub to transmit the data; the larger the target time, the larger the transmission time ratio of the data in the transmission hub. The ratio of the target time to the total time of the second preset time period is used as the transmission time ratio of the data transmitted by the transmission hub. In this embodiment, the second preset time period is set to 6 hours. The implementer can set the size of the second preset time period according to actual conditions, and it is not limited here. The purpose of setting the second preset time period is to accurately and efficiently reflect the transmission ratio of each type of data in each transmission hub.

[0090] At this point, the transmission time ratio of each type of data transmitted by each transmission hub is obtained.

[0091] Step S303: According to the transmission time ratio of each data transmitted by each transmission hub and the transmission demand degree of each transmission hub, obtain the transmission weight of each data transmitted by each transmission hub; wherein, the transmission time ratio and the transmission demand degree are both positively correlated with the transmission weight.

[0092] It is known that the transmission time ratio accurately reflects the transmission status of each type of data in each transmission hub, and the transmission demand degree reflects the importance of the data transmitted by each transmission hub. Therefore, this embodiment obtains the transmission weight of each type of data transmitted by each transmission hub according to the transmission time ratio of each type of data transmitted by each transmission hub and the transmission demand degree of each transmission hub, accurately reflecting the transmission importance of each type of data in each transmission hub, wherein the larger the transmission weight, the more important the corresponding type of data is in the corresponding transmission hub.

[0093] The calculation formula of transmission weight is: ; In the formula, is the transmission weight of the a-th type of data transmitted by the x-th transmission hub; is the transmission demand level of the xth transmission hub; is the transmission time ratio of the ath type of data transmitted by the xth transmission hub; norm is a normalization function. Get , which is not limited here.

[0094] At this point, the transmission weight of each type of data transmitted by each transmission hub is obtained.

[0095] Step S4: Obtain the target transmission storage space capacity of each type of data according to the transmission weight of each type of data in different transmission hubs and the preset minimum transmission storage space capacity of each type of data.

[0096] Specifically, in actual situations, the transmission conditions of each type of data in different transmission hubs are different. In order to ensure that each type of data can be transmitted stably and efficiently in different transmission hubs, it is necessary to keep the transmission storage space capacity of each type of data consistent during the transmission process. In the existing method, the minimum transmission storage space of each type of data is preset according to the data type of each type of data as the transmission storage space of each type of data. When the transmission amount of a certain type of data is larger, the transmission storage space set by the existing method is more likely to affect the transmission efficiency of this type of data, and because the transmission of this type of data is not timely, it is easy to cause confusion in the transmission of this type of data, affecting the security and stability of the local area network. In order to accurately obtain the transmission storage space capacity of each type of data in the local area network, this embodiment corrects the preset minimum transmission storage space capacity of each type of data according to the transmission weight of each type of data in different transmission hubs, and then accurately obtains the target transmission storage space capacity of each type of data, so that each type of data can be stably and efficiently transmitted in the local area network.

[0097] Preferably, in a method that can be implemented in this embodiment, the method for obtaining the target transmission storage space capacity is: for any type of data being transmitted, obtain the average of the transmission weights of the data in each transmission hub as the adjustment weight of the data; it should be noted that if the data does not pass through a certain transmission hub, the default transmission weight of the data in the transmission hub is 0. Among them, the larger the adjustment weight, the more important the data is in the local area network, and the greater the degree to which the transmission storage space capacity of the data needs to be adjusted in order to ensure stable and efficient transmission of the data.
