Description

technical field [0001] The invention relates to the technical field of the electric power Internet of Things, in particular to a method for interacting between a wireless communication module and a sensor in the electric power Internet of Things field. Background technique [0002] The ubiquitous power Internet of Things will become one of the main development directions for a long time in the future. Based on the good foundation laid by the strong smart grid, it will fully integrate modern information technology to create a smart grid smart grid scenario with efficient processing, real-time perception, and flexible application. Different from other IoT scenarios, the "small data" generated by various power transmission and transformation equipment in the energy power system has its own particularity: the status of equipment changes steadily and slowly, the frequency of data collection is low, the impact of key indicators exceeding the limit is large, and specific business-re...

Problems solved by technology

[0003] Due to the pre-research and experimentation of IoT-related technologies in the early stage, multiple sets of automated management systems and information platforms have been produced. Due to the different technical specifications specified by these system platforms, data sharing between platforms cannot be realized, resulting in information gaps. Closed; in addition, the understanding and specification of the sensor manufacturers for the detection of physical quantities are not completely consistent, resulting in the inconsistency of the data format generated by the sensor, which makes the information platform encounter a wide range of compatibility problems when collecting sensor data. Therefore, it is necessary to formulate a unified data model and The communication protocol realizes the standardized access of the whole industry, eliminates information islands, realizes the standardization of communication protocols, the standardization of sensor collection data format, and the standardization of communication layer and perception layer interface, which will bring an important role in promoting the industrial ecology
