Detailed Description
Reference will now be made in detail to the present embodiments of the invention, with reference to the accompanying drawings. What has been described herein is merely a preferred embodiment in accordance with the present invention and other ways of implementing the invention will be apparent to those skilled in the art from the preferred embodiment and fall within the scope of the invention.
Generally, aircraft are loaded with a variety of different on-board systems to ensure proper operation of the aircraft and for passenger safety. The airborne system can be a fuel system, a hydraulic system, a brake system, an environmental control system, a life support system and the like which are loaded on the airplane. The unit alarm system can acquire the state of each airborne system and give an alarm when abnormal operation and/or abnormal system state occurs.
The invention provides a unit alarm system with a configurable target and a configuration method for the unit alarm system, which are used for solving the problems of overlong design change flow period, complex process, high cost and the like of the conventional unit alarm system. The preferred embodiments according to the present invention will be described below with reference to the accompanying drawings.
Referring first to fig. 2, according to the present invention, a target configurable unit alarm system mainly includes an onboard system interface device, an alarm implementing device, a core processing device, a configuration file interface device, and a power system device.
The onboard system interface device is used for providing a data interface, so that the crew alarm system can be in communication connection with most onboard systems of the aircraft through the data interface so as to acquire relevant data information from the onboard systems connected with the crew alarm system. The acquired data information may be, for example, brake temperature, fuel quantity, cabin pressure, etc.
The core processing device is configured to run system software and manage and store system data. According to the functional module differentiation of the unit alarm system, the system software operated by the core processing equipment mainly comprises: an alarm logic management program, a diagram page management program, an electronic inspection list management program, a CAS (Crew alert System) message management program, a sound alarm management program and an interface management program, so as to respectively manage functional modules such as alarm logic, a diagram page, an electronic inspection list, a CAS message, a sound alarm, an interface and the like. Accordingly, these system software may be collectively referred to as a module manager.
In addition, the core processing device is respectively in communication connection with the onboard system interface device and the alarm implementation device, and is configured to receive and process data information acquired from other onboard systems. The core processing device stores a preset logic program. The core processing device can calculate the received data information according to a preset logic, and when the calculation result meets the alarm triggering condition, an alarm signal is sent out. The alarm realizing equipment can send out corresponding alarm when receiving the alarm signal from the core processing equipment. The alarm may indicate the location of the occurrence of the anomaly, the level of danger, etc.
Depending on the manner of alerting, the issued alert may include a visual alert, an audible alert, or a tactile alert. Accordingly, the alert enabling device may be a display screen, a speaker, or a tactile stimulation means, etc. Preferably, the alert implementing device is configured to issue the alert by a combination of at least the above two ways, such as a combined alert that is primary to a visual alert, secondary to an audible alert, and so forth.
The power system equipment is respectively electrically connected with the core processing equipment, the airborne system interface equipment, the alarm realization equipment, the configuration file interface equipment and the like and is used for providing electric energy for the operation of each equipment. Therefore, power supply system equipment can be used for independently supplying power to all equipment of the unit alarm system, and management of power supply is facilitated.
A profile interface device is communicatively coupled to the core processing device and is configured to enable a user to import a target profile into the core processing device. The target configuration file contains design elements for implementing configuration requirements of the unit alarm system. The core processing device is further arranged to be able to parse the target configuration file and apply the design elements contained therein to achieve the corresponding configuration requirements. In other words, the configuration file interface device can realize the interaction between the target configuration file and the core processor software, thereby completing the configuration of the unit alarm system according to the requirements.
The target configuration file may be generated by a target editor. Fig. 3 schematically shows a process of generating a target profile. First, the master manufacturer completes the unit alarm system requirement definition according to the expected requirement. Corresponding design elements, such as text, color, tone, logic, etc., are then retrieved from the requirements and entered into the target editor. The target editor is an important tool for realizing target configuration of the unit alarm system, can divide input design elements into a plurality of parts such as interface management, alarm logic, CAS information, electronic checklist, simple drawing page and sound alarm according to functional modules, defines and edits elements according to different parts, and finally generates a target configuration file. The target configuration file thus contains different design elements for fulfilling the requirements of the unit alarm system.
Referring again to fig. 2, the system software run by the core processing device further includes a target configuration file parser and a target configuration program. After the configuration file interface device imports the target configuration file, the target configuration file parser can parse the definitions and design elements of each module contained in the target configuration file. Preferably, the core processing device further comprises a memory unit. And the target configuration file analysis program stores the data analyzed by the target configuration file into the storage unit in a mode recognizable by each module management program. Then, the target configuration program determines the available data range of each module management program in the analyzed data according to the definition content of each module. Finally, each module management program reads the design elements related to the module from the storage unit according to the available data range of the module management program, and executes the module functions corresponding to the design elements. Therefore, the configuration of the unit alarm system is completed.
In addition, the target configuration file analysis program can also output the current configuration parameters in the core processing equipment through the configuration file interface equipment so as to confirm the current function configuration condition of the unit alarm system.
According to another aspect of the invention, a configuration method for the target configurable unit alarm system is also provided.
As shown in fig. 4, the configuration method generally includes the steps of:
s1: and inputting the design elements into a target editor to generate a target configuration file.
Specifically, the master manufacturer first determines the desired configuration requirements. Then, corresponding design elements, such as text, color, tone, logic, etc., are obtained from the configuration requirements and the obtained design elements are entered into a target editor. The target editor divides the design element into a plurality of parts according to the functional module, defines and edits the design element according to different parts, and finally generates a target configuration file.
S2: and importing the target configuration file into the core processing equipment through the configuration file interface equipment.
That is, the target configuration file generated by the target editor is imported into the crew alarm system via the configuration file interface device.
S3: and analyzing the target configuration file in the core processing equipment.
This step is performed by the target profile parser of the core processing device. Specifically, the target configuration file parser parses the definition and design elements of each module included in the target configuration file, and then stores the parsed result in the storage unit in a manner recognizable by each module manager. The module management program can be an interface management program, an alarm logic management program, a CAS message management program, a diagram page management program, an electronic checklist management program, a sound alarm management program and the like which are operated by the core processing equipment.
S4: and determining the available data range of each module according to the definition of each module of the unit alarm system.
This step is performed by the target configuration program of the core processing device. Specifically, the target configuration program allocates the analysis results stored in the storage unit according to the definition of each module, and determines the available data range of each module management program in the analyzed data.
And S5, reading the design elements in the data range corresponding to each module and executing the module functions corresponding to the design elements to realize the configuration requirements.
This step is performed by the hypervisor of the core processing device. Specifically, each module management program reads design elements included in corresponding data from the storage unit according to the definition of the module, and then controls the module to execute the function of the module corresponding to the design elements. Therefore, the configuration of the unit alarm system is completed.
It is to be understood that S1 in the above step may be omitted when there is an existing target profile.
Fig. 5 shows a design change flow of the target configurable unit alarm system according to the invention. As can be seen by comparing with fig. 1, in which the process of development and delivery by the suppliers is omitted, the whole process can be shortened by half a year to one year from the time when the main manufacturer completes the demand definition to the time when the flight test is completed, thereby greatly shortening the process cycle of the design change. The main manufacturer can quickly complete the software development work specified by D0-178 such as design change or requirement confirmation, software modification, software test, software verification, system test, system verification and the like of a new machine type, greatly shortens the period of design change of the unit alarm system and development of the alarm system of the new machine type unit, and saves a large amount of time cost. The design and realization of the functions of the unit alarm system can be independently and flexibly completed by a main manufacturer, so that the development cost of the unit alarm system with the configurable target only needs to be paid, and the development cost of all the subsequent design change costs and the development cost of the unit alarm system of a new machine type under the same airworthiness term do not need to be paid, thereby greatly reducing the economic cost of the main manufacturer in the aspect of the development of the whole unit alarm system. In addition, the leakage of key design parameters and a core algorithm of the unit alarm system can be effectively prevented, and the key core technology of a main manufacturer is protected.
While specific embodiments of the invention have been described above, it will be appreciated by those skilled in the art that these are by way of example only, and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the invention, and these changes and modifications are within the scope of the invention.
