The utility model provides environment monitoring equipment for transmitting data signals through a power line. The environment monitoring equipment comprises a monitoring sampling module, a digital communication interface circuit and a coupling unit, the coupling unit decouples an analog communication signal of a power supply line and interacts a digital communication signal with the digital communication interface circuit. The digital communication interface circuit converts a digital communication signal into an internal communication signal and interacts with the monitoring sampling module. The coupling unit comprises a broadband power line carrier circuit, a narrowband power line carrier circuit and a communication switching circuit, and when one of the broadband power line carrier circuit and the narrowband power line carrier circuit breaks down, the communication switching circuit switches signals needing to be interacted to the other circuit. According to the utility model, thewiring difficulty is red
