The invention discloses a safety-state-monitoring early-warning type active electronic tag comprising a controller, a storage device, a radio frequency module, a safety early warning module, a signal processing module and a safety sensing module. The controller is respectively connected with the storage device, the radio frequency module, a signal conversion module, and the safety early warning module. The signal processing module is used for receiving detection data sent by the safety sensing module, carrying out signal amplification processing and A/D conversion processing on the data, and transmitting the processed data to the controller. The controller is used for receiving the data sent by the signal processing module and controlling the storage device to store the data and analyzing and evaluation the data simultaneously. The radio frequency module is used for realizing communication between the controller and an external reading-writing device. According to the invention, the field management staff can get information of the structure and states of equipment conveniently and carry out management work with focuses, thereby reducing the potential danger of an accident.
