Abstract

The invention discloses a brake residual press detection system, which comprises a current acquisition unit, a current-voltage conversion unit, a voltage signal amplification unit, a signal comparison unit and a timer. The current acquisition unit is used for acquiring brake current, and the output end of the current acquisition unit is connected with the input end of the current-voltage conversion unit; the output end of the current-voltage conversion unit is connected with the signal comparison unit through the voltage signal amplification unit, and the signal comparison unit is connected with the timer. The working principle is simple, the brake pressure is monitored in real time under the condition that a logic microcontroller does not need to be additionally arranged in the brake control unit, the brake current and the output pressure are compared, therefore, whether the protection mechanism is started or released in the state is judged, rapid system response is realized, the tire burst risk during aircraft landing is reduced, and the aircraft landing safety is improved.

Description

technical field [0001] The invention relates to the technical field of brake residual pressure detection, in particular to a brake residual pressure detection system. Background technique [0002] At present, with the development and promotion of electronic technology, the brake pressure of aviation aircraft plays a key role in the safety of aircraft landing. The existence of brake residual pressure will cause the brake system to fail to work normally when the aircraft lands, causing the aircraft wheel to blow out, causing Security risks. Contents of the invention [0003] The purpose of the present invention is to provide a brake residual pressure detection system to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a brake residual pressure detection system, including a current acquisition unit, a current voltage conversion unit, a volta...
