It can be seen from fig. 3 that the system hardware is divided into two major parts: embedded edge gateway platform to and plug-and-play's wireless sensor module. The hardware part comprises an embedded edge gateway platform (gateway for short) and a plug-and-play wireless sensor module (wireless sensor for short).
The gateway is a central device of the whole node, is deployed at the core position of the edge node of the power system, and has the functions of: 1) connecting each wireless sensor, 2) preprocessing data, and 3) uploading the data to a cloud.

The gateway accesses the core network by using the existing Ethernet or 5G network, and extends to the cloud service of the power system, and network communication is encrypted end to ensure safety.
The wireless sensor module is firstly provided with identity authentication modules aiming at different Internet of things equipment and a communication protocol translator for translating a plurality of protocols. The protocol of the equipment of the Internet of things needs to be developed directionally according to the deployed equipment, but the protocol can be rapidly popularized to other edge nodes after the development is completed.
The wireless sensor module plays a role in an interface between the real wireless sensor and the gateway, and the wireless sensor is accessed into the gateway through a unified and universal interface. The wireless sensor module main functions include: 1) the hardware is accessed to a general interface of the gateway, 2) the traditional gateway is replaced by a corresponding network protocol to be connected with the wireless sensor, and 3) the embedded security identification module is used for giving identification information to the wireless sensor of the gateway.

It should be noted that the present invention does not encompass the wireless sensor itself, but rather provides an integrated solution to mainstream wireless sensors.
In the case of the background art, the edge wireless sensors of the system a and the system B can use the wireless sensor module provided by the system to access the edge gateway platform universally through the unified interface. Therefore, the edge end only needs one edge gateway platform, the repeated utilization rate of the equipment is greatly improved, the equipment expense is reduced, and the additional maintenance cost is also reduced.
The software part of the gateway of the invention is developed based on a complete edge operating system. In order to match the wireless sensor module, a universal wireless sensor driver is arranged in the bottom layer of the operating system. Within the operating system, there are additional modules for secure encryption and wireless sensor device identification in addition to the conventional task scheduler and task execution unit.
Therefore, the method is suitable for the deployment and the upgrade of the edge nodes of the power system. In newly deployed nodes, the technology can be used as a unified universal extensible platform, the requirement of easy system maintenance is met, and convenience in system upgrading, transformation and maintenance in the future is met.
