摘要（英）：

The invention discloses an engineering machine intelligent fault diagnosis system and method and an engineering machine. The engineering machine intelligent fault diagnosis system comprises a vehicle-mounted main controller and a fault diagnosis device, wherein the vehicle-mounted main controller is used for collecting and outputting work state parameters of the engineering machine, and the fault diagnosis device is used for receiving the work state parameters and carrying out fault diagnosis on the engineering machine according to the work state parameters. By means of the technical scheme, the vehicle-mounted main controller inside a cab in the engineering machine can be directly used for collecting the work state parameters for the fault diagnosis, a single-chip microcomputer or other control devices are not required to be additionally arranged for collection, the cost is low, the development period is short, the fault diagnosis can be effectively carried out on the engineering machine, the maintenance level is improved, and the machine-stop losses are reduced.
