Embodiment Construction

[0039] The following is further described in detail through specific implementation methods:

[0040] Such as figure 1 As shown, a data transmission method of the Internet of Things in this embodiment uses figure 1 As shown in the tree network architecture, the network includes a main node and two levels of sub-nodes, which are respectively represented by sub-nodes and sub-sub-nodes. The method includes the following steps:

[0041] S1: The master node transmits data packets to the next-level child nodes directly connected to it; each level of child nodes transmits data packets to the next-level child nodes directly connected to it after receiving data;

[0042] S2: The master node calculates the proportion of the number of sub-nodes that have completed data reception, and transmits data packets to sub-nodes at all levels that have not completed data reception after the proportion of the number reaches the preset value.

[0043] S1 specifically includes:

[0044] S1-1: The ...

Abstract

The invention relates to the technical field of Internet of Things data transmission, in particular to an Internet of Things data transmission method and system, and the method comprises the followingsteps: S1, enabling a main node to transmit a data packet to a next-level sub-node directly connected with the main node; each stage of sub-node transmits a data packet to the next stage of sub-nodewhich is directly connected with the sub-node after completing data receiving; S2, enabling the main node to calculate the number proportion of the child nodes completing data receiving, and transmitdata packets to all levels of child nodes not completing data receiving after the number proportion reaches a preset value of the number proportion, wherein the to-be-transmitted data is upgraded data, and version upgrading is carried out after all levels of child nodes receive the upgraded data. According to the Internet of Things data transmission method and system provided by the invention, theproblems of network congestion, data loss and the like caused by the fact that the Internet of Things equipment distributes data to the network in the whole network can be solved, and the data transmission efficiency of the network is improved.

Description

technical field [0001] The invention relates to the technical field of Internet of Things data transmission, in particular to a method and system for Internet of Things data transmission. Background technique [0002] With the rapid development of network communication technology, it provides a favorable opportunity for the development of Internet of Things technology. The Internet of Things (IoT) is composed of many devices with heterogeneous characteristics (such as sensors, smart phones and embedded systems, etc.). , in the Internet of Things, in addition to the work data of each device that needs to be transmitted, there are often some internal control data that need to be transmitted to all devices in the network, such as configuration parameter data, firmware update data, etc. When transmitting these internal control data, often It needs to occupy the entire network. There is no optimization method for these data transmissions in the prior art, but the data transmissio...
