The invention belongs to the technical field of 
transformer substation internet-of-things 
system structures and design thereof, and particularly relates to a 
transformer substation full-internet-of-things 
system based on a 
wireless sensor and an edge gateway. The 
system comprises a micro-power 
wireless sensor, an intelligent controller, an intelligent electric meter and an edge Internet of Thingsgateway. The micro-power 
wireless sensor communicates with the edge 
Internet of Things gateway in a LoRa micro-power wireless communication mode; the intelligent controller communicates with the edgeInternet of Things gateway in an RS485 mode; the intelligent electric meter communicates with the edge 
Internet of Things gateway through high-speed power line carrier communication; and the intelligent electric meter supports active reporting of a power failure event while acquiring 
power consumption information; the edge 
Internet of Things gateway is divided into a hardware layer, an 
operating system layer, a basic function layer and an edge 
service layer. According to the system, the information is searched through the edge gateway, and the information is processed through 
edge computing, so that the problem that massive computing is difficult to access in a 
centralized computing mode is solved. Compared with the traditional on-line 
monitoring system, the cost is greatly reduced by using the novel micro-
power consumption wireless sensor.
