Tractor electrical system fault diagnosis method based on multiple agents

The invention discloses a multi-agent-based tractor electrical system fault diagnosis method, which comprises the following specific steps: step 1, when a tractor is started to operate, a state monitoring agent performs online real-time monitoring; 2, when the state monitoring agent sends an early warning or alarm signal, sending a diagnosis request to a fault diagnosis agent through a fault diagnosis user interface; 3, submitting a fault phenomenon observed by a user to a state monitoring agent, collecting data through a sensor, and sending a current I and a voltage U in a fault state to a fault diagnosis agent system; step 4, according to the collected electrical fault data, the system management agent quickly locates to the corresponding electrical system subsystem, and then manages and coordinates the fault diagnosis task; and step 5, positioning the subsystems, accurately implementing fault diagnosis, obtaining original data of diagnosis through a state monitoring agent, and completing fault diagnosis of
