The signal acquisition and simulation data structure management module 40 may be composed of an industrial personal computer and various bus signal boards (ARINC429, ARINC664, ARINC825, etc.) used in the simulator interface control module 30, or an acquisition-side industrial control system combined with the control module 10 is separately built.
Specifically, the simulator 20 generates an analog signal according to a control instruction sent by the control module, and sends the analog signal to the simulator interface control module 30, the analog signal is collected into a collected signal through the simulator interface control module 30, the collected signal is converted into a digital string, the digital string is packed into a program flow packet according to a timestamp and sent to the signal collection and simulation data structure management module 40, the program flow packet is analyzed by the signal collection and simulation data structure management module 40, the analyzed signal is sent to the control module 10, and the analyzed signal is sent to the redundant cloud data synchronization display control module 50 according to the timestamp, so that the redundant cloud data synchronization display control module 50 stores and displays the analyzed signal. In addition, the control module 10 compares the received analyzed signal with a preset analysis signal, and adjusts the control command according to the difference between the analyzed signal and the preset analysis signal when the difference between the analyzed signal and the preset analysis signal is greater than the preset value, so that the difference between the analyzed signal and the preset analysis signal is smaller than the preset value.
For understanding, the following description exemplifies the whole operation process of the avionics functional test system by taking the landing gear test in the aircraft functional test as an example, but the present application is not limited thereto.
Before describing this example in detail, a brief description will be given of the state of the aircraft after obtaining an instruction to lower. After the airplane obtains an instruction of needing to descend, under the condition of automatic driving, a flap needs to be released and a speed reduction plate needs to be opened according to the speed requirement in a descending stage, and then an airspeed signal is one; after obtaining the indication of the descending height, the horizontal tail wing and the aileron need to be continuously adjusted so that the descending height of the airplane meets the requirement, and the required height is fed back and is a product obtained by integrating various signals of a GPS (global positioning system), a radar and air pressure; when the speed reaches below a certain limit, allowing the undercarriage to be released; when the undercarriage is grounded, the proximity sensors sense signals and feed the signals back to the avionic system, so that the airplane wheel is allowed to brake. A series of signals have a certain logical relationship with each other, and after the signals are transmitted to the avionic system, the signals are logically judged by an analysis unit in the avionic system, so that corresponding actions are started, and the safe operation of the airplane is ensured.
In this example, the simulator 20 generates an analog signal according to a control instruction sent by the control module 10, where the analog signal may include, for example, a signal indicating whether the airplane wheel is on the ground (a signal corresponding to each proximity sensor), and the simulator interface control module 30 collects the analog signal and analyzes the physical meaning of the collected signal at the same time, because the signal sending required by the test is time-sequential and logical, the collected signal needs to be converted into a digital string by the simulator interface control module, and the digital string is packed into a program flow packet according to a timestamp and sent to the signal acquisition and simulation data structure management module 40. The signal acquisition and simulation data structure management module 40 acts like a virtual landing gear in the execution of this test case. When a program flow package is received through the signal acquisition and simulation data structure management module 40, the program flow package is analyzed into values corresponding to the sensors, and after the values are judged through the combined action with the control module 10 (namely, an approaching state is given), if the parameter requirement of the test is met, a signal that the undercarriage is located and locked is fed back to the control module 10, and meanwhile, the state and related signals are sent to the redundant cloud data synchronous display control module according to the time stamp to be stored and displayed. When the feedback meets the judgment condition (that the undercarriage has fallen in place) in the automatic test case, the undercarriage lifting process is continuously executed, at this time, the simulator 20 sends a signal on the ground as a premise of lifting the wheel, and then the similar process is automatically executed. If the parameter requirement of the test is not met, the control module 10 resends the control instruction according to the received signal, so that the simulator 20 further generates a corresponding simulation signal according to the control instruction of course, and the response of the simulator to the signal at this time is further verified through the avionics function test system. All the processes and states can be monitored and recorded through the control module 10, and the states can be observed in the redundant cloud data synchronous display and control module 50. Therefore, a complete test management platform for optimizing, searching, intelligently compiling, automatically loading and verifying the avionics and related system function test schemes in real time is realized, and the construction of a core architecture platform of the full-machine integrated avionics function test intelligent test system is realized.
In summary, in the present embodiment, through the combined action of the control module, the simulator interface control module, the signal acquisition and simulation data structure management module and the redundant cloud data synchronous display control module, the problem that the test system in the prior art is in the later functional test after the aircraft assembly is completed and is not suitable for the earlier stage research of the assembly functional test is solved, the development of the functional test program and the actual application condition of the simulator are experimentally verified, the automation application scenario is reproduced, and the reliability of the functional test automation test and the production efficiency are improved.

Specifically, the multi-bus data transmission management sub-module 31 collects and summarizes the signals generated by the simulator 20, and performs physical meaning analysis of the signals through the first document management sub-module 32, because the signal transmission required by the test is time-sequential and logical, that is, which signal is transmitted when, so that the test execution sub-module 34 needs to intervene, and transmits the time-sequential test signals to the simulation data structure management module 40 on the bus (here, this is also equivalent to simulating the flow of the real aircraft sensors processing and transmitting instructions through the avionic system). That is, when an automatic test flow is compiled, signals generated by simulation of the specific system simulator 20 are controlled and collected according to the test flow and the management requirements of the ICD document, target address information is loaded, and converted into specific time-sequenced bus data streams according to the data bus simulation technology and the requirements of time sequence, a test execution strategy is established in the test execution system, and finally signal excitation output is performed in the form of the time-sequenced bus data streams through the bus data board card.

The simulation cockpit display and control console 53 is built in a generalized simulation cockpit mode and used for displaying various system parameters and information which can be obtained in the whole cloud data synchronization network in the cockpit after a model is loaded. Namely, the redundant cloud data synchronous display control module performs distributed storage on the analyzed data stream; in addition, the missing parameters can be supplemented by the general airplane flight simulation data server 52; meanwhile, the data and command lines stored through the cloud are sent to the simulation cockpit display and control console 53 and displayed in the simulation cockpit display and control console 53. However, the test system in the prior art is used for the later functional test after the final assembly of the airplane is completed, and is not suitable for the early-stage research of the functional test of the final assembly, and especially, when part of the signal types required to be simulated cannot be provided or are lost, the operation of the whole system cannot be realized.
Illustratively, parameters of 5 systems need to be displayed in the cockpit to form a complete state display of the aircraft cockpit, and then one of the systems simulates a signal generation parameter through the simulator 20, and if the other 4 system parameters are not supplemented completely, the parameter logic judgment function in the distributed data center server 51 has no way to send data to the simulated cockpit display and control console 53, and if the complete aircraft state cannot be seen on the cockpit display and control platform, the 4 system parameters to be supplemented are provided through the simulated cockpit display and control console 53. That is, the data in the simulated cockpit display console 53 is displayed as completely and logically related as possible.

The distributed data center server 51 realizes multi-terminal storage of data by using a distributed mechanism, realizes redundant backup, and realizes verification, sharing and service centralized management of redundant networked data through network equipment. The distributed data center server 51 utilizes a distributed mechanism to store the avionics data to be displayed in a distributed storage mode, so that the key data are stored in a large quantity and are called in real time, and the problems that the function test cannot be carried out and the display control platform cannot normally display the data due to data loss caused by the failure of a single storage server are prevented; the content of the redundant cloud storage is divided into redundant storage and data cloud calling, so that real-time synchronous backup of data in different places is realized, and safer transmission and calling of the data are realized through a cloud storage technology. Meanwhile, the hardware scale of laboratory stored data can be simplified, the storage resources of different places are fully utilized, and the network architecture is simplified. And meanwhile, the problem of data reading congestion is solved. Because the avionics system needs to call a large amount of data in real time and each instrument and display in the cockpit display, when one channel reads a large amount of data, the other large amount of data can be read from the redundant data stored in a distributed mode in other channels, and the possibility of data congestion of a single channel is overcome.
On the basis of the above scheme, optionally, the control module comprises an upper computer.
