Intelligent pressure gauge

The invention relates to the technical field of a pipeline. An intelligent pressure gauge comprises a pressure gauge main body capable of measuring pressure bearing capacity of a pipe. The pressure gauge main body comprises a pressure sensor. The pressure gauge main body also comprises a bluetooth communication module. The pressure sensor is connected with the bluetooth communication module through an analog-to-digital conversion module. The pressure gauge main body is connected with a mobile terminal through the bluetooth communication module. The communication module is selected, and the bluetooth communication module is selected and used between the pressure gauge main body and the mobile terminal; the distance between the pressure gauge and the mobile terminal can be limited by utilizing the information that the communication distance of the bluetooth communication module is limited; on one hand, fraud of measurement data can be reduced, and on the other hand, a mobile phone can belocated based on a posit
