The invention relates to the technical field of aviation, particularly to an engine reverse-thrust control system, and aims to solve the problem that a conventional reverse-thrust system is relatively low in safety. The engine reverse-thrust control system disclosed by the invention comprises a left actuating cylinder assembly, a right actuating cylinder assembly, a left synchronous shaft lock, a right synchronous shaft lock, a throttle table backstepping microswitch, a backstepping controller, backstepping control valve and an engine interface device, wherein the left synchronous shaft lock and the right synchronous shaft lock are controlled to be unlocked by unlocking control signals of the throttle table backstepping microswitch; through the combined action of the unlocking control signals and wheel load signals, the backstepping control valve controls the left actuating cylinder assembly and the right actuating cylinder assembly to respectively drive a left backstepping slide cover and a right backstepping slide cover to be opened, so that a reverse-thrust device can be prevented from being accidentally opened, the safety of the system is high, and the system meets the requirement for seaworthiness safety.
