    专利说明:

    [0001] The present invention relates, in general, to man-machine interfaces, in particular for aircraft, and more particularly relates to a button. Hall effect control panel for digital cockpit man-machine interface for aircraft cockpit. The aircraft cockpit control panels are indeed equipped with a number of control buttons that are manually manipulated by the pilots for the performance of one or more avionics functions. These are generally electromechanical control buttons, for example push buttons incorporating switches or rotary knobs with potentiometer or any other control device by rotation of a button (rotary switch, encoder, ...) . As it is understood, the number and size of the control buttons impose constraints that must be taken into account by the control panel manufacturers.
    [0002] In addition, in the state of the art, the control buttons provide power switching and are therefore part of the supply circuit of the bodies they control. Depending on the nature of the elements controlled, a control panel may be provided with rotary knobs, which may include several predetermined angular positions of selection or smooth rotation, or pushbuttons. It is therefore necessary to provide various types of rotary knobs or pushbuttons which must be permanently fixed on the control panel in a required configuration. Thus, it is generally not possible to replace a type of button, for example a push button, by another type of button, for example rotary to, for example, adapt 3036842 2 to a specification imposing a configuration specific to the control panel. In view of the above, the invention proposes a universal control button for a man-machine interface that can be mounted interchangeably on such an interface. Another object of the invention is to provide such a control button which has increased reliability and in a small footprint. The invention therefore relates to a universal control knob 10 Hall effect for human-machine interface, comprising a base intended to be mounted on the interface and a set of interchangeable modules manually manipulable each of which is mounted on the base and each comprising a bipolar magnet, the base being provided with means for detecting the magnetic field emitted by the magnet. Thus, thanks to the interchangeable control modules that are mounted on a universal base, a control panel can be configured from generic components selectively mount on the interface. In addition, the use of a Hall effect knob can greatly improve reliability. In one embodiment, the detection means are adapted to detect a displacement in rotation and / or in translation of the magnet.
    [0003] Advantageously, the control module comprises lighting means and a lighting board controlling the lighting means from lighting signals coming from the interface. In other words, the button also provides a signaling function making it possible, in particular, to easily identify the position of the button or to provide additional information to the pilot. In one embodiment, the control module comprises an assembly of at least one lug each fitting into a housing made in the base for the mechanical fixing and the electrical connection of the control module, the lug and the housing 3036842 being provided with complementary contacts for the transmission of lighting and power signals. Note that the control module assembly includes a smooth rotation control module, a rotary control module comprising a control position encoding or a pushbutton control module. In the case of rotary control knobs, it will be advantageous to use push-pushable actuating buttons. Advantageously, the base and the modules are provided with redundant and separate detection and control circuits. In this case, it can be provided that the detection and control circuits are connected by a communication bus. The object of the invention is also, according to a second aspect, a human-machine interface comprising a set of buttons as defined above. Other objects, features and advantages of the invention will become apparent on reading the following description, given solely by way of nonlimiting example, and with reference to the appended drawings, in which: FIG. side perspective of a first embodiment of a control button according to the invention; FIG. 2 illustrates another configuration of the control button according to FIG. 1; and FIG. 3 illustrates the assembly of a control button according to the invention. FIGS. 1 to 3 show a control button according to the invention, designated by the general numerical reference 1. This control button is intended to be mounted in a digital panel of a cockpit man-machine interface. of aircraft and to be manually manipulated by the pilot for performing one or more avionics functions.
    [0004] As previously indicated, this is a universal Hall effect push button, which includes a control module 2 and a universal base 3. The base 3 is intended to be fixed on a digital control panel cockpit of the aircraft and comprises for this purpose a set of feet, such as 4, and pins 5 to be connected to complementary pins provided on the panel for transmitting, to the digital panel, control signals generated during the manipulation of the control module 2 and the transmission thereto of supply signals or control signals of the control module 2. As can be seen in FIG. 3, the universal base 3 comprises a body comprising a set of housings 6, here two in number, made in the form of slots in which the tabs 7 provided on the control module. As can be seen, the housings 6 are provided with a number of contacts intended to cooperate with corresponding contacts provided on the tabs 7 for the transmission of the control signals supplied by the control module to the digital panel and the control signals. supply and control of the control module. As illustrated in Figure 3, the control button is assembled from several interchangeable control modules 25 which selectively mount on a universal base 3 capable of receiving different types of control members. The control module used is chosen according to the type of function ordered and the nature of the control commands. It may be a button push button type 2a, a rotary knob providing a position encoding at several predetermined positions. It may for example be a rotary knob 2b providing a six-position encoder or a rotary knob 2c providing a 12-position encoding. Of course, the number of predetermined positions is in no way limiting. It would also be possible to provide a 32-bit encoding. According to another embodiment not shown, the rotary knob can still be a push button smooth rotation.
    [0005] However, in the various modes of implementation of the rotary knobs, it will advantageously provide an additional mode of actuation pulled and pushed to, if necessary, to be able to replace a push button. In all cases, the control modules are mounted by interlocking on the universal support 3 to constitute a Hall effect button. The control modules incorporate for this purpose a bipolar magnet whose position is controlled during the manipulation of the button while the base comprises means for detecting the magnetic field emitted by the bipolar magnet. In this case they are Hall effect sensors that measure the magnetic field emitted by the bipolar magnet integrated in the control module. Of course, the Hall effect sensor is adapted to detect both a translation movement and a rotational movement of the bipolar magnet so as to be able to detect a change in the magnetic field both during rotation of a rotary knob control module that during the translation of a push button control module or rotary knob incorporating a pull and push command.
    [0006] Furthermore, the control modules are provided with lighting means to provide the pilot with information concerning the state of the controlled function or to signal the zone to be manipulated. It may for example be a light edge surrounding the area to be manipulated or one or more light points indicating the position of the control module. It can also be lighting means in the form of a light ring or indicator light on the pushbuttons. In these various embodiments, a multi-color display will advantageously be used. Multicolor light-emitting diodes (RGB) will preferably be used for this lighting function, which have the advantage of being able to recreate any color by additive synthesis of the red, green and blue components.
    [0007] Each control module is thus provided with a lighting card, identical for all the buttons, controlled by the universal base 3 from activation orders of the lighting means coming from the digital panel. Finally, it will be noted that, in order to improve the reliability of the control buttons, it will advantageously be provided that the detection circuits, in particular the Hall effect detectors integrated in the base, as well as the control circuits which control the control modules, are redundant and separated. In this respect, it is possible to provide that the base 3 comprises two Hall effect sensors, two separate communication buses with the control modules, notably incorporated in the housings 6, two lighting boards for, for example, lighting by half of the lighting means, two power supply circuits and two control microcontrollers of the control modules.
    [0008] Advantageously, a synchronization bus will be provided between these redundant and separate detection and control circuits in order to maintain a complete behavior of the control button even when a malfunction occurs within one of these detection and control circuits. for example within one of the communication buses. As it is conceivable, the invention which has just been described, which uses a universal base and a set of control modules makes it possible to achieve all the control buttons that are traditionally mounted on a panel of a cockpit of aircraft 30 through the use of a universal base which is capable of genetically providing detection of the manipulation of any type of control module for retransmitting the actions of rotation, pushed or pulled to the controller of the control panel.
    [0009] It should be noted that, unlike the cockpit components conventionally used in the state of the art, the control button which has just been described does not provide any power switching function of the control current but ensures detection. from the position of the control module which is retransmitted to the control panel controller. In other words, the control button is intended only to transmit information translating the position of the control module and to receive control and supply signals, the power switching function being implemented. by the control panel controller. In addition, the control function does not implement any mechanical element since the detection of the position of the control module is effected by the Hall effect sensor integrated in the base. It has been found that such a control button makes it possible to provide a command with increased precision insofar as the control signals coming from the control button are digital and non-analog signals, and this, in a reduced space requirement. . Such a control button has increased reliability achieved by removing the mobility of electronic parts.
    [0010] Furthermore, such a control button, which is controlled from digital signals and which provides digital control signals, is able to integrate perfectly into a digital control panel of an aircraft cockpit and this, with increased reliability and reduced footprint.
    [0011] Finally, in the various embodiments described, a reduction in the height of the control button is obtained, making it possible to obtain a consequent decrease in the thickness of the control panel in which it is mounted. In this respect, it was found that the reduction in height could reach or even exceed 30%. 30
