Abstract

The invention discloses a dual redundancy control device for position detection and retraction control equipment and a control method thereof, comprising first and second position detection and retraction control devices, first and second position detection and retraction control devices The configuration of the device is the same, including the combination of the central processing unit, the data memory and n-way output driving circuit connected with the central processing unit; the first and second position detection and retraction control devices are externally connected with different position identification codes. The data communication is carried out through the RS422 bus, wherein the communication data includes the respective status information of the first and second position detection devices; the first and second position detection and the output drive circuit of the same number in the retractable control device are connected together. External hydraulic solenoid valve. The invention provides a method for solving the work time balance of a high-power drive circuit, simultaneously solves the partial shortcoming of the current main control and standby control equipment switching, and improves the security of the system.

Description

technical field [0001] The invention belongs to the technical field of redundancy design of position detection and retractable control equipment, and particularly relates to a dual redundancy control device of position detection and retractable control equipment and a control method thereof. Background technique [0002] The landing gear system is the key and important system of the aircraft. The position detection and retraction control equipment is the action control mechanism of the landing gear system. The position detection and retraction control equipment of the aircraft (hereinafter referred to as equipment) will be designed with redundancy technology. [0003] Redundancy technology is one of the design methods for the system to obtain high reliability, high security and high survivability. Especially when the quality and reliability of components or parts are relatively low, and the general design can no longer meet the reliability requirements of the system, the red...
