The present invention relates to a system for the prevention of hearing damage in tractor drivers, designed to protect the driver's hearing from noise and vibration of a typical agricultural machine, a tractor, which uses a high-powered internal combustion engine as a power source to perform high-torque tasks. The system for the prevention of hearing damage in tractor drivers comprises: an engine vibration measuring unit (100) that measures the engine rotation speed (rpm) and converts the same into frequency (Hz) to measure engine vibration; and an engine noise measuring unit (200) that measures engine noise (dB). The system features a process that includes: a step 1 (S1) of comparing the frequency (Hz) measured by the engine vibration measuring unit (100) and the engine noise (dB) measured by the engine noise measuring unit (200) with a noise limit standard; and a step 2 (S-2) of issuing an alarm when the frequency (Hz) and engine noise (dB) exceed the noise limit standard in step 1 (S1).
본 발명은, 높은 토크 작업을 수행하기 위해, 대형 마력의 내연기관을 동력원으로 사용하고 있는, 대표적인 농업기계인 트랙터의 소음과 진동으로부터, 운전자의 청력을 보호하기 위한, 트랙터 운전자 청력 손상 예방 시스템에 관한 것으로, 엔진 회전속도(rpm)를 측정하여 진동수(Hz)로 변환시켜 엔진의 진동을 측정하는, 엔진 진동 측정부(100)와, 엔진 소음(db)을 측정하는 엔진 소음 측정부(200)를 가지며, 상기 엔진 진동 측정부(100)와 상기 엔진 소음 측정부(200)에서 측정된 진동수(Hz) 및 엔진 소음(db)을 한계 소음 기준과 비교하는 단계 1(S 1); 상기 단계 1(S 1)에서, 진동수(Hz) 및 엔진 소음(db)이 한계 소음 기준을 초과하는 경우에 경보를 발령하는 단계 2(S-2);로 이루어지는 것을 특징으로 하는, 트랙터 운전자 청력 손상 예방 시스템에 관한 것이다.
