Multi-device module measurement and control management
The smart switchgear can monitor and manage many modules in the cabinet, and can comprehensively and uniformly process the data of each module, and reflect the final data as the overall status data output in the cabinet. The modules include:
•Smart energy meter
· Circuit breaker
· Microcomputer comprehensive protection device
· Temperature Controller
Through the unified data monitoring of various modules and the edge computing capability provided by the intelligent switchgear, the switchgear can realize dynamic and user-customized state monitoring capabilities in the switchgear.

Edge computing operating environment support
Programmable analysis model
The working environment temperature switchgear supports the use of Typescript for programmable analysis model. Through the unified data call interface, it supports the acquisition of the data source and environment variable information set in the deployment state in the model, and can perform real-time data query and reading operations for the set data source, and pull multiple data sets for comprehensive analysis. This function provides good scalability support for smart
switchgear in different application scenarios for different customer needs, and can process and analyze all kinds of scattered and original component data in a unified way, and then convert them into unified switchgear status data.

The analysis model is written and deployed online
The smart switchgear is provided with an embedded network server, and the switchgear can be accessed in a local area network by using a web browser. The Web management interface of the switch gear is provided with the functions of online writing and deployment of an analysis model, so that the switchgear can independently analyze and process data without being connected to an external network or an upper system.

Remote Modbus device monitoring parameter configuration
The data reading and control of various digital components in the switchgear are completed through the Modbus-RTU standard communication protocol. Based on the open network programmable inter - face of the smart switchgear, it supports the remote dynamic configuration of the digital components in the switchgear through the interface, which is conducive to the maintenance and replacement of the equipment after it is put into operation. Avoid the situation that some specific components can not be replaced and maintained due to the shutdown of production.

· Event-driven bi-directional real-time communication 
· All data are formatted as JSON payloads. 
· Transform passive data reading into proactive push. 
· Any state change can be represented as a data event.
