Environmental monitoring system of transformer substation based on power line carrier communication technique

The utility model provides an environmental monitoring system of transformer substation based on power line carrier communication technique, including monitor sensor, signal modulation device, power network, signal demodulation device and server. Monitor sensor: be responsible for monitoring selected environmental information or equipment operating information to convey information data to the signal modulation device, the signal modulation device: make the information data that each monitor sensor conveying comes to be written into the power network to the information data after the modulation, the power network: undertake the task into each module power supply on the one hand, on the other hand receives the information data after the modulation to convey the signal demodulation device to them, the signal demodulation device: it reaches the server on, to receive the information data that the power network conveying comes, carry on demodulation operation back to data, the server: integrate the management to various information data.
