Abstract
In a control and energy supply system for the drive units and control units for at least two, preferably adjacent, aircraft seats, all system components are interconnected via a data bus, so that the control system of the one seat is informed of what is happening to the other seat. The servomotors of the seats can be supplied with power via two separate networks. System failure caused by loose or disconnected plug type connections, cable breakage, short circuits or a failed control unit can be avoided by said redundancy concept.
Claims22
A control and energy supply system for drive units and control units of at least two, aircraft seats, characterized in that the control unit and the drive units of one aircraft seat are connected to the control unit and the drive units of at least one further aircraft seat via a data line means, that each drive unit can be supplied with power by at least two power supply units, and that an interruption in the normal data line connection of a seat is detected and reported via the data line means to the control unit of a further aircraft seat, and control and configuration report are carried out via a partner system.
A control and energy supply system for drive units and control units of at least two, aircraft seats, characterized in that the control unit and the drive units of an aircraft seat are connected to the control unit and the drive units of at least one further aircraft seat via a data line means, that each drive unit can be supplied with power by at least two power supply units, and that an interruption in the normal current path of an aircraft seat is detected and reported via the data line means to the control units of said aircraft seat and a further aircraft seat, and the control operation is then carried out such that the current is taken from the other power supply unit.
A control and energy supply system for drive units and control units of at least two, aircraft seats, characterized in that the control unit and the drive units of an aircraft seat are connected to the control unit and the drive units of at least one further aircraft seat via a data line means, that each drive unit can be supplied with power by at least two power supply units, and that upon detection of a short circuit or of an unintended external supply the power supply of the adjacent system is switched to.
A control and energy supply system for the drive units and control units of at least two, aircraft seats, characterized in that the control unit and the drive units of an aircraft seat are connected to the control unit and the drive units of at least one further aircraft seat via a data line means, that each drive unit can be supplied with power by at least two power supply units, and that the control units exchange their status and the demands on their control tasks between each other, and in the absence of plausible information from a control unit the other control unit assumes the task thereof.
