The invention discloses an automatic equipment state evaluation monitoring device based on the fuzzy AHP theory. The device comprises an equipment state fuzzy comprehensive evaluator and an intelligent mobile equipment monitoring device. The equipment state fuzzy comprehensive evaluator is connected with the intelligent mobile equipment monitoring device through a control hall wireless communication device. The intelligent mobile equipment monitoring device comprises a vehicle body, a slewing bearing, a slewing motor component, a monitoring arm component, first, second, third and fourth overturn-preventing components, first and second rotary motors, an axle component, first, second, third and fourth lighting lamps, first and second obstacle avoidance devices and a control unit. The equipment state fuzzy comprehensive evaluator can be suitable for various types of equipment of the transformer substation, accurate data can be provided through the intelligent mobile equipment monitoring device and information is received through a movement controller without manual operation so that unmanned mobile intelligent monitoring can be realized.
