Formula, when the deice mode of the deicing subsystem is automatic mode, the icing detector detect icing thickness and with setting
Value is compared, and sends out switching signal to the controller according to comparing result, the controller controls the near infrared light hair
Injection device switchs;When the deice mode of the deicing subsystem is manual mode, near-infrared described in operating personnel's manual control
The switch of light emitting devices.
8. deicing control system according to claim 7, it is characterised in that:The master switch includes display unit and operation
Interface, the display unit, which is used to show, often saves on compartment each icing information of brake rigging, in the operation interface
Equipped with select the deicing control system for automatic mode or the button of manual mode.
