Abstract

The invention discloses a cabin pressure open loop control system, and belongs to the airplane environment control technical field; one end of the cabin is provided with an air supply pipeline; a cabin air supply flow device is arranged in the air supply pipeline; a cabin pressure sensor and a cabin temperature sensor are arranged in the cabin; the bottom of the cabin is provided with an exhaust valve; the exhaust valve is connected with an exhaust valve motor, an exhaust valve driver and an exhaust valve order forming module in sequence from top to bottom; the exhaust valve order forming module is respectively connected with the cabin pressure sensor, the cabin temperature sensor, the cabin air supply flow device, and a cabin pressure system module; the cabin air supply flow, the cabin temperature, the cabin pressure and flight height parameters are combined so as to realize the cabin pressure open loop control, thus improving cabin pressure control precision, and ensuring passengers comfortable and airplane composition safety.

Description

technical field [0001] The invention belongs to the technical field of aircraft environment control, and in particular relates to a cockpit pressure open-loop control system. Background technique [0002] At present, the main technologies applied in the field of aircraft cockpit pressure control at home and abroad include pneumatic cockpit pressure control technology, electropneumatic cockpit pressure control technology and digital cockpit pressure control technology. [0003] Pneumatic cockpit pressure control technology was used in earlier aircrafts. Since the computer control technology at that time had not been greatly developed, pneumatic cockpit pressure control technology became the main method of cockpit pressure control. Pneumatic cockpit pressure control technology can realize the control of cockpit pressure, but the accuracy of pneumatic cockpit pressure control is poor due to the long connecting pipeline of pneumatic control, high installation requirements, and h...
