Special hydraulic system detection device

The invention discloses a special hydraulic system detection device comprising a shell. A control circuit is arranged in the shell. The control circuit automatically judges the state of a hydraulic system according to a fault judgment rule and generates a state code. A pressure sensor is arranged at one end of the shell and is movably connected with an interface of a detected device through an arranged mechanical interface. A human-computer interaction interface is arranged at the end, away from the pressure sensor, of the shell, and the human-computer interaction interface and the pressure sensor are both connected and communicate with the control circuit through data lines. Automatic wireless networking can also be achieved, and the problem that cable arrangement is difficult is solved.By means of the miniature and integrated design, the problems of traditional detection devices are solved, rapid automatic detection and fault diagnosis of the state of the hydraulic system are achieved, the battlefield rapid
