Acquisition terminal of signal surge protection device

The invention relates to an acquisition terminal of a signal surge protection device. The acquisition terminal comprises a signal lightning protection device linkage module, a data acquisition unit and an acquisition sensor which are installed on a signal SPD. The signal lightning protection device linkage module is connected with the data acquisition unit and is used for outputting a damage signal to the data acquisition unit. The acquisition sensor is installed at a grounding position of a signal SPD or on a signal line and is connected with the data acquisition unit. The acquisition sensortransmits acquired data to the data acquisition unit. The data acquisition unit acquires the acquired data of the sensor according to the acquired damage signal, and transmits the acquired data to theintermediate layer or the management layer for software judgment and analysis in three transmission modes of 485 bus signals, NB-IOTs and 5G/4G. Damage judgment can be given under the protection condition, and it can be ensur
