Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific examples and with reference to the accompanying drawings.

[0020] see figure 1 , a dual-redundancy unmanned aerial vehicle brake controller, mainly composed of a main control system, a backup control system and a monitoring and arbitration unit.

[0021] The above-mentioned main control system includes a main control microprocessor, a main bus transceiver and a main internal power supply. The control enabling terminal of the main internal power supply is connected to the main power control terminal of the monitoring arbitration unit, and the power output terminal of the main internal power supply is connected to the power input terminal of the main control microprocessor. The control enabling terminal of the main bus transceiver is connected to the main transmitting and receiving c...

Abstract

The invention discloses a dual-redundancy unmanned aerial vehicle brake controller and a cold standby control method. The dual-redundancy unmanned aerial vehicle brake controller mainly consists of amain control system, a standby control system and a monitor and arbitration unit, wherein the main control system comprises a main control microprocessor, a main bus transceiver and a main internal power supply; and the standby control system comprises a standby control microprocessor, a standby bus transceiver and a standby internal power supply. The cold standby control method is adopted in thebrake controller, and components and parts of standby control system are but out to reduce the electric stresses of the components and parts, so that the problem that the life of the components and parts of hot standby control systems are influenced by the electric stresses is solved; and in design of cold standby control systems, the monitor and arbitration unit is utilized to cache current PWM signal duty cycle instructions, so that the problem that interruption exists in PWM signal output in the cold standby brake control method is solved.

Description

technical field [0001] The invention relates to the technical field of UAV brake control, in particular to a dual-redundancy UAV brake controller and a cold backup control method. Background technique [0002] Existing aircraft brake controllers usually adopt a hot backup control method for the control system, that is, the main control system and the backup control system are powered on at the same time. Since the backup control system bears the same electrical stress as the main control system, the backup control system is affected. The life of each component of the system weakens the reliability of the brake controller. [0003] Although the cold backup control method can cut off all the components of the backup control system, reduce the electrical stress of the components, and greatly improve their service life, there are still shortcomings in the existing cold backup control method, that is, it takes several Ten milliseconds to switch to the backup control system. Con...
