Abstract

The invention discloses a blower fan state monitoring system. The blower fan state monitoring system comprises a full-vibration input matching circuit. A vibration signal acquired by a sensor is input in the input end IN of the full-vibration input matching circuit, and the input end IN is connected with an anti-phase input end of a first operational amplifier by a resistor, and the anti-phase input end of the first operational amplifier is connected with a fifth pin of a chip U3A by the resistor. The in-phase input end of the first operational amplifier is grounded by a resistor, and the output end of the first operational amplifier is connected with the in-phase input end of the first operational amplifier by a feedback resistor, and the output end of the first operational amplifier is a first output end GAP1. The blower fan state monitoring system is advantageous in that real-time state monitoring of a wind turbine generator system is realized to guarantee long-term safe operation.

Description
