Abstract

The invention provides a dual-mode switch interlocking control circuit applied to an aviation liquid-cooling system. The dual-mode switch interlocking control circuit comprises an interlocking circuit and a switching circuit. A switch is controlled intelligently according to control logic. Through the interlocking circuit, mutual influences between automatic control and manual control are avoided, and interference due to personal error operation is eliminated. The dual-mode switch interlocking control circuit is applied to the aviation liquid-cooling system for the first time, and has the advantages of need of a small quantity of components and parts, simple circuit, practicability, reliability, and improvements on product stability, reliability and applicability.

Description

technical field [0001] The invention relates to a dual-mode switch interlock control circuit applied to an aviation liquid cooling system, which belongs to the field of electrical technology. Background technique [0002] At present, in the aviation liquid cooling system, in order to automatically and manually control the system and avoid mutual influence in the dual mode, the product needs to design a dual mode switch interlock control circuit. [0003] When the product is actually running on site, the automatic and manual modes will affect each other. In the manual control mode, the system needs to be operated by personnel, and automatic start cannot be realized, and it is easy to operate incorrectly; in the automatic control mode, it is easy to be interfered by manual operation, causing errors. operate. Contents of the invention [0004] The present invention is a dual-mode switch interlock control circuit applied to the aviation liquid cooling system. The circuit incl...
