1. Power safety monitoring system
Combine "cloud computing" with the power system, integrate the existing resources of the power system to the greatest extent through the power cloud, conduct analogy and analysis, provide the system with "supercomputing" capability, and more accurately realize the functions of power loss analysis and intelligent early warning. At the same time, all kinds of equipment and instruments are shared, and users use them on demand. Each user feels that they are using resources in an exclusive form, but there is no need to buy them.

2. Introduction of power safety management cloud platform
The power safety management platform is a new power distribution management platform based on big data, which applies the concept of "Internet plus". The wtq-3000 is a cloud based automation platform for substation and power distribution automation, which can realize the integration of energy management and distribution automation.

The overall scheme is divided into:
24-hour remote monitoring scheme
Wantai intelligent operation and maintenance platform scheme
Local on-line temperature monitoring scheme
