Aero-engine ignition control system with monitoring device

The invention provides an aero-engine ignition control system with a monitoring device, and relates to the design technology of aero-engines. The aero-engine ignition control system with the monitoring device is used for controlling ignitor plugs of an engine, on the basis of control through a dual-redundancy ignition relay of an engine electronic controller, a path of ignition relay is added on an interface unit of the engine of aircraft equipment, the relays of each ignitor plug are increased to three, and the ignition function of the engine can be achieved through closing of each relay. The contact state and the front end input ignition voltage quality of the ignition relay installed in an EEC are monitored in real time through the EEC, the contact state and the front end input ignition voltage quality of the ignition relay in an EIU are monitored in real time through the EIU, monitored information is fed back to the EEC through a bus, and the EEC monitors the three ignition relays and outputs a merged current finally. By means of the aero-engine ignition control system with the monitoring device, the reliability of the engine ignition system is improved, testability and the fault diagnosis capability of the engine are improved, and the safety of an aircraft is enhanced.
