Bus-structure multi-sensor distribution equipment test device

The invention discloses a bus-structure multi-sensor distribution equipment test device which comprises a signal acquisition unit, a signal processing unit, a diagnosis control unit, an operation unit, and a bus control unit completing information transmission between the units. Firstly, ultrasonic, geoelectric and infrared thermal imaging sensors of the signal acquisition unit acquire signals and convert the signals into analog electrical signals. Secondly, the analog electrical signals are filtered, amplified and de-noised in the signal processing unit, and detection data is formed based on encoding rules. Thirdly, the detection data is analyzed through an analysis algorithm of the diagnosis control unit to get a health state and form an analysis report and a map file. Finally, the operation unit displays the file and images to achieve human-computer interaction. The device provided by the embodiment of the invention has a networked mode and advanced diagnosis service, can assist in test result diagnosis, i
