Anti-condensation method of galvanized stoving varnish steel coil

The invention discloses an anti-condensation method of a galvanized stoving varnish steel coil. The anti-condensation method comprises the following operation steps that: S10, a data acquisition service controller presets an anti-condensation alarm formula by adopting a BP neural network algorithm; S20, a temperature and humidity server obtains the real-time environment temperature, the real-timeenvironment humidity and the real-time steel coil temperature through an environment temperature sensor, an environment humidity sensor and a steel coil temperature sensor and transmits the real-timeenvironment temperature, the real-time environment humidity and the real-time steel coil temperature to the data acquisition service controller through communication; S30, the data acquisition servicecontroller performs anti-condensation alarm matching calculation, and when an anti-condensation alarm formula is established, an anti-condensation alarm signal is sent to an external server; and S40,an air blower arranged in a
