Abstract
Systems and methods for shutoff valve control are provided. The system may receive a first hardware logic input, a second hardware logic input, and a weight-on-wheels (WOW) status wherein each of the first hardware logic input, the second hardware logic input, and the WOW status report a binary true or a false. The system may open the shutoff valve when each of the first hardware logic input, the second hardware logic input, and the WOW status report true. The system may close the shutoff valve when any of the first hardware logic input, the second hardware logic input, and the WOW status report false.
Claims20
A method of controlling a shutoff valve, comprising:
- receiving, by a first controller, a first hardware logic input, a second hardware logic input, a taxi condition and a weight-on-wheels (WOW) status,
- wherein each of the first hardware logic input, the second hardware logic input, the taxi condition and the WOW status report a binary true or a false;
- opening, by the first controller, the shutoff valve in response to receiving the true from each of the first hardware logic input, the second hardware logic input, the taxi condition and the WOW status;
- and
- closing, by the first controller, the shutoff valve in response to receiving the false from any of the first hardware logic input, the second hardware logic input, the taxi condition and the WOW status.
A system for controlling a shutoff valve, comprising:
- a brake hydraulic system including a proportional valve, wherein the shutoff valve is configured to interrupt fluid communication between the proportional valve and a hydraulic supply;
- and
- a tangible, non-transitory memory configured to communicate with a first controller, the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the first controller, cause the first controller to perform operations comprising:
- receiving, by the first controller, a first hardware logic input, a second hardware logic input, a taxi condition and a weight-on-wheels (WOW) status,
- wherein each of the first hardware logic input, the second hardware logic input, the taxi condition and the WOW status report a binary true or a false;
- opening, by the first controller, the shutoff valve in response to receiving the true from each of the first hardware logic input, the second hardware logic input, the taxi condition and the WOW status;
- and
- closing, by the first controller, the shutoff valve in response to receiving the false from any of the first hardware logic input, the second hardware logic input, the taxi condition and the WOW status.
An article of manufacture including a tangible, non-transitory computer-readable storage medium having instructions stored thereon that, in response to execution by a first processor, cause the first processor to perform operations comprising:
- receiving, by the first processor, a first hardware logic input, a second hardware logic input, a taxi condition and a weight-on-wheels (WOW) status,
- wherein each of the first hardware logic input, the second hardware logic input, the taxi condition and the WOW status report a binary true or a false;
- opening, by the first processor, a shutoff valve when each of the first hardware logic input, the second hardware logic input, the taxi condition and the WOW status report true;
- and
- closing, by the first processor, the shutoff valve when any of the first hardware logic input, the second hardware logic input, the taxi condition and the WOW status report false.
