Abstract

The invention provides a data accessing method and system. The method comprises the steps of receiving a transmission request of target data required by a target device, registering relative parameterinformation of the target device, wherein the relative parameter information at least includes types and transmission protocol modes of the target data, establishing a data receiving access corresponding to the target device and receiving the target data transmitted by the target device by the data receiving access, selecting a corresponding data converter from a pre-stored data converter libraryaccording to the types and the transmission protocol modes of the target data to acquire converted target data, selecting a corresponding mapping rule according to the type of the target data, and analyzing the converted target data by the mapping rule. By adoption of the method, the transmission data of different devices accesses dynamically; secondary development is unnecessary; the method is simple and efficient; the data of the multi-source heterogeneous agricultural internet of things accesses simply, effectively and steadily; and, the method facilitates the agricultural production departments and the agricultural enterprises to a certain extent.

Description

technical field [0001] The present invention relates to the technical field of data transmission, and more specifically, to a data access method and system. Background technique [0002] With the development of Internet of Things technology, the application of Internet of Things in the field of agriculture continues to deepen. The system of the Agricultural Internet of Things includes a perception layer, a transmission layer and an application layer; the transmission layer and the perception layer collect the perception data of agricultural production, and the application layer processes and applies the perception data. The data collected by the perception layer includes various agricultural production fields such as facilities, fields, aquatic products and orchards. In addition, the data transmission protocols are different, which makes the agricultural perception data have the characteristics of multiple sources and strong heterogeneity. [0003] In addition, the applicat...
