[0030] The on-authorization management device has the following functions: automatically judging the environmental state, outputting a ground signal when there is icing risk, and automatically turning on the automatic on relay.

[0031] In the present application, the anti-icing switch has three states of "on", "automatic" and "off. When the anti-icing switch is in the "on" state, the anti-icing device starts to work. When the anti-icing switch is in the "off state, the anti-icing device stops working. When the anti-icing switch is in the "automatic" state, the on-authorization management device judges the environmental state. If there is icing risk, the on-authorization management device controls the automatic on relay to be turned on, and the anti-icing device starts to work. If there is no icing risk, the on-authorization management device controls the automatic on relay to be turned off, and the anti-icing device stops working.

[0032] In the present application, a power supply is further included, which supplies power to the automatic on relay and the automatic off relay.

[0033] In the present application, the anti-icing device comprises a pipeline connecting the engine bleed air port and the engine front end air inlet, and a valve arranged on the pipeline. The pipeline extracts hot air from the periphery of the engine bleed air port, and the hot air enters the engine body through the pipeline to prevent icing. The anti-icing device adopted in the present application extracts hot air from the periphery of the engine to prevent icing, which can comprehensively utilize the engine hot air as energy and save cost.

[0034] The method of the multi-authorization control system of the aircraft air anti-icing system comprises the following steps:

[0035] Step 1: disconnect the permission management device to determine the engine state, if the engine power can be extracted, enter step 2, otherwise, the disconnect permission management device controls the automatic disconnect relay to turn on, and the anti-icing device stops working;

[0036] Step 2: when the anti-icing switch is in the "on" position, the anti-icing device starts working, when the anti-icing switch is in the "off" position, the anti-icing device stops working, and when the anti-icing switch is in the "automatic" position, enter Step 3;

[0037] Step 3: turn on the permission management device to determine the environmental state, if there is a risk of icing, the on permission management device controls the automatic on relay to turn on, and the anti-icing device starts working, if there is no risk of icing, the on permission management device controls the automatic on relay to turn off, and the anti-icing device stops working.

[0038] In step 2 of the application, if the engine power cannot be extracted, the disconnect permission management device provides a ground signal to the automatic disconnect relay to control the automatic disconnect relay to turn on.

[0039] In step 3 of the application,

[0040] If there is a risk of icing, the on permission management device provides a ground signal to the automatic on relay to control the automatic on relay to turn on, and the anti-icing device starts working.

[0041] If there is no risk of icing, the on permission management device provides an open signal to the automatic on relay to control the automatic on relay to turn off, and the anti-icing device stops working.

[0042] In summary, the application provides a multi-permission control system and method for an aircraft air anti-icing system. The multi-permission control system and method of the anti-icing system are improved based on the existing design of a certain type of helicopter air anti-icing system, and is an anti-icing control system with high automation degree, which saves the pilot's energy and reduces the pilot's operation burden.
