Definitions
- the invention relates to a functional expansion module for driving tools, in particular commercial aircraft, and an aircraft with a corresponding functional expansion module.
- LRU Line Replaceable Unit
- passenger supply modules which are arranged in the immediate vicinity of a passenger seat and, depending on requirements, can have various functions.
- Passenger supply modules are installed above each row of passenger seats in commercial aircraft. Among other things, they contain reading lamps and can also display switchable information signs, such as the seat belt sign. In addition, there is often one or more loudspeakers for on-board announcements by the pilot or the cabin crew. Oxygen masks that fall out of an opening when there is a drop in pressure in the cabin can also be part of passenger supply modules.
- the passenger supply modules are supplied with electrical power via a power supply bus and regularly have switches which can be actuated by a passenger for switching the reading lamps on and off. So that the reading lamps can be switched on and off as required, there is a constant voltage at the specified level on the power supply bus. If further functions in the area of the passenger supply modules are to be retrofitted, these can in principle be integrated into the passenger supply modules. If necessary, they can be supplied with electrical power via the power supply bus. The disadvantage of this is that in order to see new functions in the area of passenger supply modules, the passenger supply modules have to be exchanged or extensively revised.
- the invention is therefore based on the object to provide a possibility for retrofitting additional functions in the field of functional modules, in particular an aircraft, in which the disadvantages of the prior art no longer occur or only to a reduced extent.
- This object is achieved by a functional expansion module according to the main claim and an aircraft according to claim 11.
- the invention relates to a function supplement module for vehicles to supplement a function module supplied with electrical power via a power supply bus, where the function supplement module is designed to supply electrical power via the power supply bus, comprising a control device with a detection module for detecting the voltage in the power supply bus, wherein the control device is designed to deactivate the function supplement module when a first predetermined voltage variation is detected via the detection module.
- the invention also relates to an aircraft, in particular a commercial aircraft, comprising at least one function module, at least one function supplement module and one power supply bus for supplying power to the at least one function module and the at least one function supplement module, the function supplement module being designed according to the invention.
- the function supplement module has a detection module for detecting the voltage in the power supply bus to which the function supplement module is connected. sen, has and is designed to detect a variation just this voltage according to a predetermined pattern. If a corresponding first predetermined voltage variation is detected, the function supplement module is deactivated, ie the function (s) provided by the function supplement module are (at least partially) switched off and are then no longer available to the passengers.
- control in front of the control device is preferably designed to reactivate the function expansion module when a second predetermined voltage variation is detected via the detection module.
- the first and the second predetermined voltage variation can in principle be identical. However, it is preferred if the first and second predetermined voltage variations are different. This offers the advantage that, in the case of a large number of function supplement modules, these can be transferred at least by repeating the first and / or second predetermined voltage variation even in a common activation state if a function supplement module initially did not correctly detect a voltage variation and subsequently the activation state not changed. If there is no permanent malfunction of the function supplement module, the desired activation state can generally be achieved by repeating the first or second predetermined voltage variation.
- the first and / or second voltage variation comprises an interruption in the power supply, the interruption preferably being shorter than 0.1 s, more preferably shorter than 0.05 s, further preferably shorter than Is 0.02 s.
- a corresponding interruption can be generated, for example, by an electronic switch that is controlled accordingly.
- the first and / or second voltage variation can comprise a voltage modulation with a reduction in the voltage, the reduction in the voltage preferably being 10% to 30%, more preferably approximately 20% of the nominal voltage and / or the reduction preferably being shorter than 0.1 s, more preferably for less than 0.05 s, further for preferably less than 0.02 s.
- interruptions or reductions in the power supply can be "passed through” regularly by function modules and function supplement modules without the functionality of the modules being impaired.
- the interruption or reduction in the power supply is at least within the range specified Duration below the perception threshold, ie even if a reading lamp should basically flicker due to the loss of power or loss of power, this flickering is so short that it cannot be perceived by the human eye.
- the first and / or second voltage variation comprises a plurality of interruptions and / or reductions in the power supply in a respectively predetermined pattern.
- the first and / or second voltage variation can comprise a voltage modulation with sinusoidal voltage, the frequency of the sinusoidal voltage being preferably less than 400 Hz, preferably less than or equal to 200 Hz, further preferably less than or equal to 50 Hz, the amplitude preferably less than 5% of the Rated voltage is. Due to a correspondingly low frequency, there is a risk of occurrence electromagnetic incompatibility in other devices due to the voltage modulation of the power supply bus very low.
- the functional module can be a passenger supply module, with which the functional supplement module is then a passenger supply supplement module.
- the functional expansion module has at least one socket of an electrical plug connection, preferably a standardized socket, further preferably a USB socket for connecting external consumers.
- the consumer to be supplied with electrical power is not directly part of the functional expansion module, but rather an external device, such as a mobile terminal of a passenger. The passenger can operate his mobile terminal and / or charge its energy storage via the functional expansion module.
- the functional expansion module has at least two, preferably at least three sockets.
- the function module to be supplemented is a passenger supply module that regularly supplies more than one seat or passenger, it is advantageous if the function supplement module is also designed to supply more than one seat or passenger.
- the function supplement module can have a sensor and / or a camera.
- the data captured by the at least one sensor and / or the at least one camera are preferably temporarily stored on a memory module provided directly in the function expansion module.
- the memory module can, if necessary, via a Any data connection, which is not necessarily permanent, can be read out, for example via an optionally producible wireless or wired data connection during the maintenance of an aircraft.
- the function supplement module can also be designed for any other functions.
- the function expansion module is designed as a current switch, which can be arranged between the power supply bus and a function module and is designed to pass electrical power from the power supply bus to the function module.
- the function expansion module can be easily interposed between the power supply bus and the function module without requiring changes to the power supply bus and the function module. The assembly of such a single physical unit is very simple:
- the aircraft can comprise a signal transmitter unit, with which, on request, a predetermined voltage variation in the Power bus is introduced.
- the voltage variation can be the first or second predetermined voltage variation, which can be detected by the function supplement module according to the invention as a signal for activation or deactivation.
- the request can be made by operating a switch or the like. take place directly on the signal transmitter unit.
