[0002] The sink node is mainly responsible for the connection between the sensor network and the external network. The sink node connects a large number of sensor nodes. The node decodes the sensor data, then the response of the sink node to decode the sensor data is very slow, and often cannot be decoded

Embodiment Construction
[0042] The present application provides a method and system for shunting sensor data, which are applicable to electronic equipment.
[0043] see figure 1 , the present invention provides a method for offloading sensor data, which is applied to user terminals and convergence nodes connected to the Internet of Things, and is described in detail as follows:
[0044] S1. The user terminal sends a sensor data reading request to the aggregation node, the sensor data reading request is used to read the sensor data reported by the target sensor node, and the sensor data reading request includes the target product Information, target function type, current decoding component version number;
[0045] Wherein, the current decoding component version number is the current decoding component version number of the user terminal.
[0046] Wherein, if the decoding component is not currently installed on the user terminal, the version number of the current decoding component of the user termi...

The invention belongs to the field of software, and provides a sensor data distribution method and a sensor data distribution system. The sensor data distribution method comprises the following stepsthat: an aggregation node judges whether a version number of a decoding component in a sensor data reading request is within version numbers of decoding components of sensor data encoding template identifiers carried by M bound sensor data or not; if not, identifying that the user terminal cannot decode the sensor data reported by the target sensor node, and transmitting an upgrading reminding message to the user terminal; the user terminal transmits an upgrading request to the aggregation node; the aggregation node returns decoding component upgrading information and the sensor data reportedby the target sensor node to the user terminal, wherein the decoding component upgrading information comprises an installation package of the decoding component with the maximum decoding efficiency parameter and an equipment identifier of the target sensor node; and the user terminal operates the decoding component with the maximum decoding efficiency parameter to decode the sensor data reported by the target sensor node. According to the sensor data distribution method and the sensor data distribution method system, the pressure of decoding the sensor data by the aggregation node can be reduced.
Description
technical field [0001] The invention relates to the field of software, in particular to a method and system for splitting sensor data. Background technique [0002] The sink node is mainly responsible for the connection between the sensor network and the external network. The sink node connects a large number of sensor nodes. If the node decodes the sensor data, the response of the sink node to decode the sensor data is very slow, and often it cannot be decoded. Therefore, in order to alleviate the decoding pressure of the sink node, how to distribute the sensor data of the target sensor node to the user terminal for decoding is an urgent problem to be solved. In addition, the data format of the sensor data of the target sensor node is various. How to let the user terminal decode the sensor data reported by the target sensor node is also an urgent problem to be solved. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the ob...
