The invention relates to the technical field of electric power operation security and protection, in particular to a safety reminding device for an electric power operation engineering vehicle. The technical problem that an existing electric power operation engineering vehicle lacks a reasonable and effective reminding device is solved. The device utilizes a vehicle-mounted power supply, and further comprises a three-terminal regulator IC1 and a voice integrated circuit IC2. The designed safety voice reminding device has the advantages of being low in cost, good in tone quality and short in development period, and voice can be controlled only through a vehicle door switch. Simulation results show that the system is reasonable and feasible in design scheme and good in parameter real-time performance, has the advantages of being clear in voice, low in cost, high in anti-interference performance and the like, and can be widely applied to various engineering vehicles. And meanwhile, the recording circuit is rapid and simple to mount and dismount, and the complexity of the circuit structure is reduced while the practical application is met.
