Problems solved by technology

In the prior art, during this period of time, the information of the sensor network cannot be transmitted to the background server in real time, that is to say, the background server cannot obtain the information of the sensor network in real time, which will affect industrial production. Special sensitive environments such as earthquake monitoring will bring huge impact and loss

Abstract

The invention discloses a method for achieving sensor network data transmission and sink nodes. The method includes the steps that when the sink nodes do not receive responses of a gateway to which the sink nodes belong within preset time, the sink nodes request the adjacent sink nodes for temporary access; point-to-point connection is established between the adjacent sink nodes and the sink nodes and data from the sink nodes are uploaded through the gateway to which the sink nodes belong. By the adoption of the method, when the gateway can not make the responses to the sink nodes, the sink nodes upload the sensor network data through a gateway to which the adjacent sink nodes belong, and it is guaranteed that information of a sensor network is transmitted to a background server in real time.

Description

technical field [0001] The invention relates to sensor network technology, in particular to a method for realizing sensor network data transmission and a convergence node. Background technique [0002] As an important part of the Internet of Things, the sensor network is responsible for obtaining information about the physical world and transmitting it to background applications. The sensor network mainly includes sensor nodes and aggregation nodes. Among them, the main function of the sensor node is to collect information from the sensor network, and transmit the collected information to the aggregation node through the pre-built sensor network, and then the aggregation node aggregates the collected information and transmits it to the gateway. After protocol conversion, it is uploaded to the background server for use in the background of the application. [0003] The gateway plays an important role in the application of the entire sensor network. The gateway plays the role...
