Various embodiments of the present disclosure relate generally to the field of aircraft information systems and, more particularly, to an aircraft interface device for accessing aircraft information streams.
Today, there exists an onboard aircraft device known as an Aircraft Interface Device (“AID”). Typically, the AID device connects to avionics and helps convert data into readable forms by other devices, such as electronic flight bags (EFBs). This is especially difficult to do across different aircraft types/operators, since the format of the avionics data varies from type to type and operator to operator. Since onboard devices are certified devices, software is expensive to develop and costly to change. Thus, although avionics recording/analyzing has been done on the ground as well as within onboard devices, barriers exist to using other devices, such as mobile devices, to decode raw avionics recordings and display data for an end user. Such a decoder application in a mobile device would provide significant advantages from a cost savings point of view since it may save money that currently is expended on certified software. Installation of a typical AID may be time consuming and may require individually wiring each Line Replaceable Unit (LRU) from which the AID needs data. Further, if the raw data is required to be off boarded via a satellite or other communications connection while in air in order for it to be decoded by ground servers, additional costs and inefficiencies are incurred by transmitting data to the ground and then receiving the results via a communications channel that may be expensive to operate.
The present disclosure is directed to overcoming one or more of these above-referenced challenges.
In one aspect, a computer-implemented method for providing vehicle data to a mobile device is disclosed. The method may include: receiving raw vehicle data from one or more vehicle data streams using one or more protocols; recording the received raw vehicle data from the one or more vehicle data streams in a file format; and transmitting the recorded vehicle data to a mobile device having at least one application configured to interpret the transmitted vehicle data.
In another aspect, a method for providing vehicle data to applications on a mobile device is disclosed. The method may include: receiving, on the mobile device, vehicle data from a vehicle in a file format; interpreting the received vehicle data by at least one application on the mobile device; decoding, by the at least one application on the mobile device, the interpreted vehicle data; and displaying the decoded vehicle data on at least one of the mobile device or a second device.
In yet another aspect, a system for providing vehicle data to a mobile device is disclosed. The system may include: a memory having processor-readable instructions therein; and at least one processor configured to access the memory and execute the processor-readable instructions, which when executed by the processor configures the processor to perform a plurality of functions, including functions for: receiving raw vehicle data from one or more vehicle data streams using one or more protocols; recording, to the memory, the received raw vehicle data from the one or more vehicle data streams in a file format; and transmitting the recorded vehicle data to a mobile device having at least one application configured to interpret the transmitted vehicle data.
Additional objects and advantages of the disclosed embodiments will be set forth in part in the description that follows, and in part will be apparent from the description, or may be learned by practice of the disclosed embodiments. The objects and advantages of the disclosed embodiments will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosed embodiments, as claimed.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate various exemplary embodiments and together with the description, serve to explain the principles of the disclosed embodiments.
Various embodiments of the present disclosure relate generally to an vehicle interface device for accessing vehicle information streams, and to a mobile device-connected vehicle interface device, and related methods. The systems and methods described below are described as applying to an aircraft but embodiments can be applied to any type of vehicle that implements an interface device for receiving vehicle data.
As discussed above, it may be difficult and costly to access information provided by an aircraft interface device due to certification requirements and differences between aircraft types. Ground-based solutions incur further costs due to expensive communications infrastructure. Embodiments of the present disclosure provide solutions to these barriers by using an onboard gateway device to perform raw recording of avionics data, such as data provided by a Quick Action Recorder (QAR or A717) or A429 data, and sending of the avionics data, wired or wirelessly, to a mobile device to be interpreted and parsed. Data such as airspeed or altitude could then be supplied by the decoder application to other mobile applications, such as EFB applications. One potential benefit of this approach is that the certified software that records avionics data may remain simple and common across aircraft types, and, thus, may be less prone to updates. The non-certified software portion may then be more easily and affordably updated to account for applying the gateway to new aircraft types or changes to existing installations.
Embodiments of the present disclosure may allow an application to be ported more easily to other mobile device applications to access the avionics data to support their functionality. Embodiments of the present disclosure may further allow the onboard device processing required to be minimized, potentially freeing up processor throughput for other tasks or to allow use of less powerful processors, potentially saving costs related to heating, power, weight, and equipment.
Embodiments of the present disclosure may be integrated with a connected aircraft platform, such as the Aircraft Data Gateway-300 (gateway) manufactured by Honeywell International Inc. Such a device may be installed on commercial aircraft, and connected to read data acquisition unit (DAU) data, such as Quick Action Recorder (QAR) data over an ARINC 717 connection, and one or more A429 connections.
The gateway may be loaded with configuration files that allow the recording function to be configured per the aircraft settings, so that the gateway software function can be used as common software across aircraft that have different standards for sending QAR or A429 data. The mobile device application may then be configured to request either A429 or QAR data from the gateway through a wired or wireless connection. The gateway may, for example, send a recording file or stream the raw data (potentially compressed or compressed/encrypted) to the mobile device for the mobile application to decode.
Alternatively, the gateway may stream the raw data to the mobile device directly. However, other means of transmitting the data to the mobile device may be employed, consistent with the present disclosure. For example, the gateway may provide an interface for users to request historical data from the gateway's recordings, so that the mobile device may not require an application to be running in the background at all times. The interface may allow users to obtain data for events that happened when the application was not open. The mobile application may then either use or send specific decoded parameters to another mobile application (possibly another module of the same application). An application such as an electronic flight bag (EFB) application may use the data to display data about the aircraft or do analytics/predictions with the data.
Embodiments of the present disclosure will be described in reference to the gateway. However, this disclosure should not be interpreted as limited to such a configuration. Integration with other connected aircraft platforms is possible.
Mobile device 115 may include at least one mobile application 125. Mobile device 115 may be connected to vehicle gateway 110 by either a wired connection or a wireless connection. The stored raw vehicle data may be transmitted from vehicle gateway 110 to mobile device 115 as a timestamped file or streamed to mobile device 115 in a first file format. The raw vehicle data may be interpreted and decoded by the at least one application 125 on mobile device 115. The at least one application 125 on mobile device 115 may include a software module, such as data interpreter 130, that may be configured to interpret the raw vehicle data on all platforms that vehicle gateway 110 is integrated on. The at least one application 125 on mobile device 115 may then decode the interpreted vehicle data. For example, the vehicle data may be decoded to actionable vehicle parameters. The actionable vehicle parameters may comprise data parameters relevant to the vehicle, such as speed and travel path.
The at least one application 125 on mobile device 115 may also format the decoded vehicle data to a second file format for use with one or more second protocols. The decoded and/or formatted vehicle data may then be displayed either on the mobile device 115 or a second device. For example, mobile device 115 may include a second application, such as weather application 135, to display integrated weather on a moving map. The VID software stack 100, described above, may provide the functionality of a VID, while not relying on embedded software to interpret the data. The VID software stack 100 may configure the gateway 110 to be integrated onto other platforms without updates to any certified software. Upon request of the at least one application 125, gateway 110 may pass the at least one application 125 the requested recorded vehicle data or stream raw data words directly to the mobile device 115. The recordings may be compressed and encrypted. The recordings may be from current travel data or historical travel data.
Mobile device 215 may include at least one application 225. Mobile device 215 may be connected to gateway 210 by either a wired connection or a wireless connection. The stored raw aircraft data may be transmitted from gateway 210 to mobile device 215 as a timestamped file or streamed to mobile device 215 in a first file format. The raw aircraft data may be interpreted and decoded by the at least one application 225 on mobile device 215. The at least one application 225 on mobile device 215 may include a software module, such as data interpreter 230, that may be configured to interpret the raw aircraft data on all platforms that gateway 110 is integrated on. The at least one application 225 on mobile device 215 may then decode the interpreted aircraft data. For example, the aircraft data may be decoded to actionable aircraft parameters, such as flight parameters. The actionable aircraft parameters may comprise data parameters relevant to the aircraft, such as airspeed and altitude.
The at least one application 225 on mobile device 215 may also format the decoded aircraft data to a second file format for use with one or more second protocols, such as ARINC 429 (A429), ARINC 717 (A717), RS-422, or the like. The decoded and/or formatted aircraft data may then be displayed either on the mobile device 215 or a second device, such as an electronic flight bag (EFB). For example, mobile device 215 may include a second application, such as weather application 235, to display integrated weather on a moving map. The AID software stack 200, described above, may provide the functionality of an AID, while not relying on embedded software to interpret the data. The AID software stack 200 may configure the gateway 210 to be integrated onto other platforms without updates to any certified software. Upon request of the at least one application 225, gateway 210 may pass the at least one application 225 the requested recorded aircraft data or stream raw data words directly to the mobile device 215. The recordings may be compressed and encrypted, for example as a ZIP file. The recordings may be from current travel data or historical travel data.
Data communication in embodiments of the present disclosure may be wired or wireless data connections. For example, wired data connections may include Ethernet (such as 10/100BaseT), A429, A717 (QAR) data, GPS data, high or low speed avionics recording, discretes (such as “Weight on Wheels,” LRU Mode Selectors), RS422 (available, such as Aircraft Condition Monitoring System). Wireless data connections may include one or more antennas (such as external client antenna, cabin WAP antenna, belly WAP Antenna), which may be able to connect to either Wi-Fi or cellular.
The terminology used above may be interpreted in its broadest reasonable manner, even though it is being used in conjunction with a detailed description of certain specific examples of the present disclosure. Indeed, certain terms may even be emphasized above; however, any terminology intended to be interpreted in any restricted manner will be overtly and specifically defined as such in this Detailed Description section.
