Intelligent detection system device for respiration valve

The utility model relates to an intelligent detection system device for a respiration valve. Voltage signals of oil tank pressure measured by a sensor are amplified through an amplifier, are then transmitted to a high-precision voltage-to-frequency (V/F) converter to be converted into digital signals and are next transmitted to a singlechip, system setting parameters are transmitted to the singlechip through a liquid crystal display (LCD) and a keyboard, the singlechip processes and judges the data, and the intelligent detection system device has the characteristics that the automation degree is high, the detection is accurate, the performance is stable, the operation is simple, the moving is flexible, the requirement on the environment is low, and the like. The intelligent detection system device for the respiration valve of an oil tank has high practicability in the safety assurance work of an oil depot.
