Description

Technical Field

[0002] Switches with indicator lights are one of the commonly used switch components in the electrical field. Switches with indicator lights generally include pressable switches and switches that only indicate status. Pressable switches with indicator lights are usually used to indicate the status information of the onboard system or component, including indicating whether the system is working normally / abnormally, as well as switch status information (ON / OFF / NORM, etc.), whether the switch component is working normally; switches with indicator lights that only indicate status are usually used to indicate whether the onboard system or component is working normally / abnormally. The current conventional design is to transmit a signal to the switch to light up the indicator light, drive the light component to light up, and the indicator light will not light up if there is no electricity, related driver failure or light component failure. If the switch is used on an aircraft, there will be a situation where the switch and related components fail to light up when the aircraft is in operation, which will cause panic to the pilot and affect flight safety. In addition, it is impossible to accurately locate whether it is a light component failure or a failure of other components during maintenance, and it must be disassembled and taken back to the original factory for maintenance, which has a lot of maintenance hours and high maintenance costs.

[0021] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. In the following detailed description, many specific details are set forth to provide a thorough understanding of the described exemplary embodiments. However, it is obvious to those skilled in the art that the described embodiments can be practiced without some or all of these specific details. In other exemplary embodiments, well-known structures or processing steps are not described in detail to avoid unnecessarily obscuring the concepts of the present disclosure.

[0022] In this specification, unless otherwise specified, the term "A or B" used throughout the specification refers to "A and B" and "A or B" rather than meaning that A and B are exclusive.

[0023] Figure 1 An example of the system architecture of the switch with indicator light 100 according to an embodiment of the present invention is explained.

[0024] Pressable switches with indicator lights are usually used to indicate the working status information of airborne systems or components, including indicating whether the system is working normally / abnormally, as well as switch status information (ON / OFF / NORM, etc.), whether the switch component is working normally; switches with indicator lights that only indicate the status are usually used to indicate whether the airborne system components are working normally / abnormally. For example, the APU switch on the aircraft control panel, when the switch activation status light is on (green), indicates that the system is in an operational state. When the status light is off, it means that the system is not working or has not reached the working state. If the above indicator lights are not on, it is easy to cause panic to the pilot. The above-mentioned airborne system components may include: electromechanical management system, power system, environmental protection system, cabin pressurization system, power system, environmental control system, hydraulic system, fuel system, etc.

[0025] In the embodiments of the present application, in particular in the switch design with an indicator light having an adaptive dimming function of the present invention, the entire switch design may include a plurality of lamp assemblies, namely lamp assembly 1 to lamp assembly N, each lamp assembly may correspond to a driver, namely driver 1 to driver N, such as Figure 1As shown in . In an embodiment of the present application, the power detector 110 can monitor the power of the above-mentioned N drivers in real time, and at the same time feed back the monitored power information to the controller 120. Drivers 1 to N can be uniformly controlled by the controller 120. In an embodiment of the present application, the controller 120 can receive power from the power module 130, control signals (for example, external control instructions) from the digital signal controller 140, and power signals fed back by the power detector 110, etc. The power module 130 outputs a DC power supply to power the entire switch with an indicator light, and the external control instructions of the digital signal controller 140 can come from the pilot's operation and / or the digital signal fed back from the cross-linked airborne system (for example, the airborne maintenance system equipment 150). In an embodiment of the present application, the controller 120 can combine the above-mentioned three-party information to perform information processing, and then reversely control the N drivers. The design architecture of the switch 100 is as shown in FIG. Figure 1 shown.

[0026] In the embodiment of the present application, when the switch with indicator light 100 is in the power-on state, the pilot or the cross-linked airborne system (for example, the airborne maintenance system device 150 therein) can give an external control instruction to the digital signal controller 140. When the digital signal controller 140 receives the instruction, it transmits the control signal to the controller 120, and the controller 120 allocates the brightness index and / or the power corresponding to the brightness index to the drivers 1 to N through the power detector 110. The drivers 1 to N can drive each lamp assembly 1 to N to light up, and the power detector 110 can detect the output power of the drivers 1 to N in real time and feed back the power information to the controller. At the same time, the power information (for example, indicating normal power information) fed back to the controller 120 by the detector 110 can be stored in the controller 120. It should be understood that in the present application, the controller allocating the brightness index to the driver and / or the lamp assembly can correspond to giving the power corresponding to the brightness index to the driver and / or the lamp assembly.

[0027] In an embodiment of the present application, depending on the power supply power of the power module 130 and the control instructions received by the digital signal controller 140, the switch with indicator light 100 has a constant total brightness index L (unit: candela per square or lux). The constant total brightness index L can have one or more settings, depending on the input mode definition of the power module and the digital controller. For example, if the entire switch system (including multiple different switches with lights) has two mode settings of bright or dark, the power input and the digital controller will obtain control information of two different brightnesses, that is, two different brightness indexes, for example, L1 and L2. The above two indexes are modes that the pilot can freely control the conversion, and both refer to the normal working state of the aircraft indicator light. In an embodiment of the present application, when N lamp assemblies or drivers are all normal, the brightness index assigned to each driver by the controller 120 is L / N, then the brightness of each lamp assembly driven is consistent, at this time the power detector 110 detects normal power information, and the normal power information is fed back to the controller 120, and the controller 120 still assigns the brightness index L / N to each driver and stores the power information fed back by the detector. It should be noted that although the distribution of the total brightness index L and its corresponding power in the specification of the present application is described with reference to the average distribution by the controller to each driver, the distribution of the total brightness index L and the corresponding distribution of the total power in the present application may not be average, and may be based on a mapping or function of the brightness index and the index of the lamp component / driver, as is understood by those skilled in the art.

[0028] In the embodiment of the present application, when one or more lamp components or drivers fail, the corresponding driver output power will be abnormal, and the power detector 110 can continuously or periodically detect power information and feed back the detected power information to the controller 120. The controller 120 compares the received power information with the normal power information corresponding to the brightness index assigned to each driver by the controller 120, determines which driver or drivers have abnormal output power, and calculates the number M of drivers with abnormal output power. Subsequently, the controller 120 can recalculate the brightness index L / (NM) and its corresponding power, assign it to the remaining (NM) drivers with normal output power and assign the brightness index 0 to the M drivers with abnormal output power, so that the remaining (NM) lamp components will generate new brightness to compensate for the brightness value corresponding to the faulty lamp component or driver, so as to achieve the effect that the total brightness L of the indicator light is constant. Additionally or alternatively, the controller 120 can also calculate the number M of drivers with abnormal output power, and directly assign the brightness index and its corresponding power obtained by its previous assignment to the remaining (NM) drivers with normal output power. At the same time, the power information (eg, power information indicating abnormality) fed back by the detector 110 to the controller 120 may be stored in the controller 120. Figure 2

[0029] In an embodiment of the present application, all power information stored in the controller 120 may be transmitted to the onboard maintenance system via the digital signal controller 140, such as Figure 1 For example, during system maintenance, the staff can directly or indirectly locate the fault by exporting the power information stored in the controller 120 through the onboard maintenance system device 150, thereby improving the efficiency of fault detection. In an embodiment of the present application, additionally or alternatively, the controller 120 can locate the fault by providing the onboard maintenance system with an index of the abnormal driver or lamp assembly.

[0030] Additionally or alternatively, although Figure 1 Only one controller 120 is shown in the figure, but the controller 120 may also be a plurality of controllers, which separately control each lamp assembly and driver. The plurality of controllers 120 must be able to communicate with each other to more effectively distribute the brightness index.

[0031] Figure 2 An example of a process flow for implementing a switching system according to an embodiment of the present invention is illustrated.

[0032] In step 205, the controller of the indicator light switch may allocate the brightness indexes of the N lamp assemblies and transmit them to 1 to N drivers. Figure 1 As described, the total brightness index L of the switch with indicator light 100 is constant and this index can be stored in the controller 120. The total brightness index L should depend on the power of the power module 130, and can be changed by the control command received by the digital signal controller 140. In the initial power-on state, after the controller receives the control command of the digital signal module, it calculates the brightness index of L / N for each lamp component and distributes this brightness index to N drivers. After each driver obtains the brightness index, it drives the corresponding lamp component to light up and emit the same brightness.

[0033] In step 210, the power detector can detect the output power of each driver in real time and feed the output power information back to the controller. In an embodiment of the present application, the power detector 110 detects the output power of each driver in real time and feeds the output power information back to the controller 120. Under normal circumstances, the controller will maintain the initial brightness index and each lamp assembly will be driven at the same brightness.

[0034] In step 215 , the controller may store all power information detected by the power detector and determine whether there is abnormal output power.

[0035] If no abnormal output power is detected in step 215, the controller will maintain the initial brightness index and each lamp assembly will be driven at the same brightness. In an embodiment of the present application, the controller 120 may (in step 220) allocate a brightness index L / N to each driver, and (in step 225) transmit the allocated brightness index L / N to N normal drivers via the detector, and the driver (in step 230) drives the lamp assembly to work according to the brightness index.

[0036] If more than one abnormal output power is detected in step 215, the controller 120 will recalculate and assign the brightness index. In the embodiment of the present application, when a certain lamp assembly or driver fails, the output power of the corresponding driver is abnormal, the controller 120 will detect an abnormal power, and can recalculate the brightness index L / (N-1) and assign it to the remaining (N-1) drivers, and assign the brightness index 0 to the failed driver or the driver corresponding to the failed lamp assembly, so as to drive each lamp assembly to generate a new brightness. In the embodiment of the present application, when M lamp components or drivers fail, the controller 120 detects M abnormal powers (at step 235), and can recalculate the brightness index L / (NM) (at step 240), distribute it to the remaining (NM) drivers corresponding to the normal powers, and (at step 245) output the distributed brightness index L / (NM) to (NM) normal drivers via the detector, and (at step 240) distribute the brightness index 0 to the M drivers corresponding to the abnormal powers, and (at step 245) output the distributed brightness index 0 to the M normal drivers via the detector, thereby driving each lamp component to generate a new brightness. Under the coordinated operation of the power detector 110 and the controller 120, the total brightness of the indicator light remains constant at L. It should be noted that when all lamp components or drivers fail, the brightness of the indicator light is 0.

[0037] All power information detected by the above power detectors is stored in the controller and transmitted to the onboard maintenance system through the digital signal controller. During maintenance, the staff can directly or indirectly locate the fault through the power information, thereby improving the efficiency of fault detection. When one or more lamp components or drivers fail, the corresponding driver output power is abnormal. At this time, the maintenance personnel can directly locate the fault through the exported power information. When the switch with indicator light is not lit as a whole, there are two situations: 1. All lamp components or drivers are faulty. At this time, the maintenance personnel can still directly locate the fault through the exported power information; 2. Not all lamp components or drivers are faulty. At this time, the maintenance personnel can determine that other components are faulty through the exported power information, which greatly reduces the scope of fault diagnosis. Therefore, during maintenance, the maintenance personnel can directly or indirectly locate the fault by exporting the information stored in the controller, thereby improving the fault detection rate.

[0038] Figure 3 A method for operating a switch system (eg, Figure 1 An example of a process flow for a control device of the switch 100 in FIG.

[0039] In an embodiment of the present application, the control device may include, for example Figure 1The switch 100 in the embodiment of the present invention, and the control device may include an indicator light, a power control module and a power detector, wherein the indicator light may include a plurality of lamp assemblies, each lamp assembly is driven by a corresponding driver, as shown in FIG. Figure 1 As described, a control device can turn on or off a system component associated with it.

[0040] In step 305, the method may include: determining, by a power control module of the control device, the total power provided to the indicator light based on the working state of the system component associated with the control device. In an embodiment of the present application, when the indicator light is on (green), it may indicate that the system component associated therewith is in an operable working state, and when the status light is off, it indicates that the system component is not working (for example, power off) or has not reached an operable working state or a normal working state. In an embodiment of the present application, if the entire switch system also has two modes, bright or dark, the power input and the digital controller will obtain control information of two different brightnesses, that is, two different brightness indicators, for example, L1 and L2, and the power control module may determine the total power to be provided to the indicator light based on the above different brightness indicators.

[0041] At step 310, the method may include: allocating the total power to a plurality of drivers corresponding to a plurality of lamp assemblies by a power control module. In an embodiment of the present application, the total power may be evenly allocated to the plurality of drivers. Additionally or alternatively, the total power may be allocated to the plurality of drivers based on a mapping or function of a brightness index to an index of the lamp assembly / driver. The sum of the brightness indexes allocated to the drivers is constant.

[0042] At step 315, the method may include: detecting, by a power detector, the output power provided by each of the plurality of drivers to the corresponding lamp assembly. In an embodiment of the present application, the output power provided by each of the plurality of drivers to the corresponding lamp assembly is detected continuously or periodically (for example, once every 0.1 s). Additionally or alternatively, the detection of the output power provided by each of the plurality of drivers to the corresponding lamp assembly may be triggered based on a system signal.

[0043] In step 320, the method may include: the power detector transmits a feedback signal indicating the output power to the power control module. In an embodiment of the present application, the output power indicated in the feedback signal may be stored in the controller. For example, when one or more lamp components or drivers fail, the corresponding driver output power is abnormal, and the maintenance personnel can directly locate the fault through the derived power information.

[0044] In step 325, the method may include: in response to detecting that the output power of one or more drivers is abnormal, the power control module shuts down the one or more drivers. In an embodiment of the present application, the power control module may assign a brightness index of 0 to the driver with abnormal output power to shut down the driver with abnormal output power.

[0045] In step 330, the method may include: the power control module reallocates the power allocated to one or more drivers to the remaining drivers. In an embodiment of the present application, the power control module may directly reallocate (e.g., averagely or based on mapping) the power allocated to one or more drivers to the remaining drivers, or reallocate the total power to the remaining drivers.

[0046] The above describes the switch system of the indicator light with adaptive dimming function on the civil aircraft according to the present invention. Compared with the prior art, the method of the present invention has at least the following advantages:

[0047] 1) The switch with an indicator light with adaptive dimming function has a design with multiple lamp components and multiple drivers, and the indicator light function is more stable than the traditional switch;

[0048] 2) Switches with indicator lights with adaptive dimming function can achieve adaptive dimming, without the need for additional equipment such as sensors to keep the total brightness of the indicator lights constant, thus preventing the switch from malfunctioning during use and affecting flight safety;

[0049] 3) During maintenance, the staff can export the power data stored in the controller through the onboard maintenance system equipment to quickly and accurately locate the fault directly or indirectly, improve maintenance efficiency and reduce maintenance costs;

[0050] The controller of the switch with indicator light design can also be multiple controllers, which separately control the drivers of each lamp component. The controllers can communicate with each other to more effectively distribute the brightness index.
