Problems solved by technology

In the current aircraft design, the door control panel often does not provide accurate and sufficient indication of the door status, and the door operator may misuse it, resulting in damage to the door lock mechanism of the door
What's more serious is that the control panel lacks an effective mechanism to prevent human misoperation or accidental action. Once misoperation or accidental action occurs, it may lead to personal safety accidents

Embodiment Construction

[0028] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings, but the protection scope of the present invention should not be limited thereby.

[0029] The aircraft door has an associated latch and lock mechanism, so that it can be bolted and locked after the aircraft door is closed, so as to ensure the safety of the aircraft door. The crew can operate the hatch through the hatch operating component, such as opening / closing the hatch, latching / unlatching the hatch, locking / unlocking the hatch, etc.

[0030] figure 1 is a block diagram of an aircraft door control device 100 according to one embodiment of the present invention. The aircraft door control apparatus 100 may include various door operating components 110 that receive operating inputs and generate door operating signals. For example, the door operating assembly 110 may include a door switch, a lock switch, and the like. When an operator (for example...

Abstract

The invention discloses airplane cabin door control equipment and a control method. The airplane cabin door control equipment may include a cabin door operation assembly, a sensor signal processing unit, a cabin door state indicator and a motor controller, the cabin door operation assembly receives an operation input and generates a cabin door operation signal; the sensor signal processing unit isused for receiving and processing a cabin door state detection signal generated by a cabin door state sensor so as to generate a cabin door state signal; the cabin door state indicator is used for indicating the cabin door state according to the cabin door state signal; and the motor controller generates a motor control signal for controlling an actuator associated with the cabin door in accordance with the cabin door operation signal and the cabin door state signal. The invention further discloses an airplane cabin door control method and a device for airplane cabin door control.

Description

technical field [0001] The present invention generally relates to the field of aircraft, and in particular to an aircraft door control device and control method. Background technique [0002] After experiencing two cargo door accidents in the 1990s, the FAA issued the FAR25-114 amendment in 2004, which greatly improved the safety requirements of the door. In the current aircraft design, the door control panel often does not provide accurate and sufficient door status indication, and the door operator may misuse it, resulting in damage to the door lock mechanism. What's more serious is that the control panel lacks an effective mechanism to prevent human misoperation or accidental action. Once misoperation or accidental action occurs, it may lead to personal safety accidents. Therefore, it is necessary to design a safe and reliable hatch control panel and indication interface, which not only provides accurate and sufficient operation instructions for operators, but also preve...
