Online monitoring system for complex multivariable parameters of low-dew-point double-runner dehumidifier

The utility model discloses an on-line monitoring system for complex multivariable parameters of a low-dew-point double-runner dehumidifier. The system comprises a local server, a switch, a converterand a double-rotating-wheel dehumidifier collection controller, the server is connected with the double-rotating-wheel dehumidifier collection controller through the switch and the converter, and thedouble-rotating-wheel dehumidifier collection controller is connected with a sensor module and an adjusting module. According to the method, a multi-power coupling comparison calculation module, a variable-temperature dehumidification control module and a variable-air-volume dehumidification control module are included. An optimal control strategy is selected through the multi-power coupling comparison calculation module, and the variable temperature dehumidification control module and the variable air volume dehumidification control module operate respectively. The dew point temperature is effectively and dynamically
