Embodiment Construction

[0067] This embodiment is a dual-mode controlled anti-skid brake control method for unmanned aircraft. The anti-skid brake system using the modified method adopts a conventional fly-by-wire anti-skid brake system or a conventional all-electric anti-skid brake system. The following embodiments are based on a fly-by-wire anti-skid braking system.

[0068] This embodiment includes the following steps:

[0069] Step 1, determine the system status.

[0070] The BIT fault detection signal is sent out by the anti-skid brake control box, and the brake components of the system respond to the BIT fault detection signal and generate a feedback signal. :#00H (no fault).

[0071] Step 2, determine the response object.

[0072] Normal "sync word: #0EBH", "frame length: #06H", "checksum: #80H" [set "data word" UART L : #40H (corresponding to output left brake volume V L : #40H), "data word" UART R : #40H (corresponding to the output right brake volume V L : #40H) correct "checksum"]; ...

Abstract

The invention discloses an anti-skid braking control method for an unmanned aircraft based on dual-mode control, aiming at solving the technical problem that an existing anti-skid braking control method for the unmanned aircraft is poor in safety. According to the technical scheme, the method comprises the following steps: determining a system state, a response object, an output current and the state of a hydraulic lock; and sending state information to a flight control computer. The method is used for tests or data collection of an offensive unmanned aircraft sample in a development stage, so that the risk is reduced and the safety of the unmanned aircraft is improved. When the offensive unmanned aircraft fights, the electromagnetic environment is interfered by the enemy, and an unmanned combat system is no long under control, thus, an anti-skid braking system controlled by a pilot is automatically started. The anti-skid braking control method for the unmanned aircraft based on dual-mode control is further suitable for automatic brake for taking off and landing of other types of aircrafts with cabins.

Description

technical field [0001] The invention relates to a control method for anti-skid braking of an unmanned aircraft, in particular to a control method for anti-skid braking of an unmanned aircraft based on dual-mode control. Background technique [0002] Reconnaissance unmanned aircraft, such as the US "Global Hawk", only have a single landing brake control mode. Due to reasons such as small size, this aircraft cannot achieve dual-mode control of anti-skid brakes. Attack-type unmanned aircraft is similar to ordinary manned aircraft in appearance, and can realize dual-mode control, but the current attack-type unmanned aircraft has not proposed an anti-skid braking method based on dual-mode control. Attack unmanned aerial vehicle has the characteristics of heavy weight and high cost. The anti-skid brake control system is very important for the anti-skid brake system during take-off and landing. Therefore, the reliability of the anti-skid brake system directly affects the safety of...
