Abstract
PURPOSE: To prevent the fault by discriminating the specific human voice collected in a microphone arranged in agricultural machine through an electronic circuit to stop the engine thus enabling automatic stoppage of agricultural machine.
CONSTITUTION: When turning a switch 2m on to start the engine E, human voice discriminating device 2 is functioned to collect all work noise in microphones 1, 1. When alarm cry enters into the microphone 1 during the work, said cry is smoothed through ALC circuit 2b to constant volume. Then the cry applied with voltage amplification through low frequency voltage amplifier 2c is discriminated to human voice and mechanical noise through frequency discriminator 2d. Said human voice is amplified through low frequency power amplifier 2e, then full-wave rectified through a detector 2g to produce DC voltage which sequentially activates the relays 2j, 2k through an amplifier 2h and to operate the engine stopping device 4 through solenoid relay 3.
