Step 2: the running engine parses the predetermined test command and performs data processing.
The operation engine calls a function in the function library to generate external data according to a preset test command, firstly, external input data are generated, the external input data are sent to an interface module of the comprehensive monitoring system through the AFDX board card, corresponding system output data fed back are received through the AFDX board card, and an automatic test tool generates an AFDX test result according to the system output data and the external input data.
The running engine calls a function in the function library to read an AFDX (avionics full Duplex switched Ethernet) message list in the product configuration file, wherein the AFDX message list comprises AFDX message names which are communicated with the integrated monitoring system through an AFDX bus; the operating engine reads AFDX characteristic parameters stored in the function library, wherein the AFDX characteristic parameters comprise necessary parameters of AFDX bus communication; the operation engine calls a function in the function library to acquire AFDX characteristic parameters and AFDX network parameters and AFDX message formats corresponding to the AFDX message names from the airplane network database according to a preset test command; and the running engine generates external input data according to the AFDX message name, the AFDX characteristic parameters, the corresponding AFDX network parameters and the AFDX message format. Since the integrated monitoring system and the external system communicate through the AFDX network, the AFDX network parameters are all necessary parameters for the AFDX board to transmit a message, and thus the AFDX network parameters include at least one of a virtual link ID, a sub virtual link ID, a communication port, a source address of UDP, an end address of UDP, a BAG (Bandwidth Allocation Gap), a transmission frequency, and a flow control.
An example is given here: the AFDX characteristic parameters in the functional library are only form parameters and do not have actual parameters, so that the actual parameters need to be acquired through subsequent steps, and the functional library acquires all parameters of the corresponding message from the aircraft network database according to the AFDX message name and the AFDX characteristic parameters. For an example, it is assumed that the AFDX message name obtained by the runtime engine reading the AFDX message list in the product configuration file includes message 1 and message 2, and the AFDX feature parameters stored in the function library read by the runtime engine include VL ID, UDP Source IP, UDP Destination IP, and BAG. The message formats and all parameters of the messages 1 to 5 are stored in the aircraft network database, and usually, the relevant data of each message is stored in the form of an array, for example, the storage form is assumed as follows:
all relevant data corresponding to message 1 is stored as:
all relevant data corresponding to message 2 is stored as:
the storage format of all relevant data of messages 3 to 5 is also similar to that of messages 1 and 2, but the specific data of each parameter may be different, and is not shown in detail in this application.
The AFDX message format corresponding to the message 1 and the AFDX network parameters respectively corresponding to the AFDX characteristic parameters, which are read from the aircraft network database by the operating engine according to the obtained AFDX message name and the obtained AFDX characteristic parameters, can be represented as follows:
VL ID1, UDP Source IP IPs1, UDP Destination IP IPD1, and BAG1, where ID1, IPs1, IPD1, and BAG1 are the read AFDX network parameters.
Similarly, the AFDX message format corresponding to the message 2 and the AFDX network parameters respectively corresponding to each AFDX characteristic parameter, which are read from the aircraft network database by the operating engine according to the acquired AFDX message name and the AFDX characteristic parameters, may be represented as:
VL ID2, UDP Source IP IPs2, UDP Destination IP IPD2, and BAG2, where ID2, IPs2, IPD2, and BAG2 are the read AFDX network parameters.
Furthermore, in order to facilitate the subsequent test of other test scripts, the running engine stores the corresponding relationship between the AFDX message name and the AFDX network parameters and the AFDX message format to form a configuration file, so that the industrial personal computer reads the configuration file to obtain the corresponding AFDX network parameters and the AFDX message format when executing other test scripts, and the AFDX network parameters and the AFDX message format which are analyzed under normal conditions can be placed in a peer directory of the airplane network database in the form of the configuration file.
When other test scripts are executed to call the configuration file, the operation engine firstly reads the current airplane network database and the product configuration file and detects whether the current airplane network database and the product configuration file correspond to the configuration file, if the current airplane network database and the product configuration file correspond to the configuration file, the airplane network database and the product configuration file are not changed, and at the moment, the operation engine directly reads the configuration file according to the AFDX message name to acquire the corresponding AFDX network parameter and AFDX message format. Otherwise, the change of the aircraft network database and/or the product configuration file is indicated, and at the moment, the corresponding AFDX network parameter and AFDX message format are obtained from the aircraft network database again according to the AFDX message name and the AFDX characteristic parameter.

The running engine calls a function in the function library to read the product configuration file and acquires an Ethernet message list in the message list, wherein the Ethernet message list comprises an Ethernet message name and an Ethernet message structure which are communicated with the integrated monitoring system through an Ethernet channel; the running engine calls a function in the function library to obtain a corresponding excitation parameter from the excitation parameter library according to a preset test command; and the running engine generates external excitation data according to the Ethernet message name, the Ethernet message structure and the excitation parameter. The Ethernet message structure comprises a message packet header, a message length, a unique identification number and a message body, and corresponding data in the excitation parameter library is packaged according to the Ethernet message structure; for messages that need to be sent periodically, the function library sends a predetermined value, which is a value in a default scenario read from the library of excitation parameters.
Furthermore, the industrial personal computer stores at least two different product configuration files, the product configuration files are stored correspondingly to the attribute information of the comprehensive monitoring system, when the running engine reads the product configuration files, the running engine reads the attribute information of the comprehensive monitoring system currently tested through the AFDX board card, reads the product configuration files corresponding to the attribute information of the comprehensive monitoring system, and stores a plurality of product configuration files in the industrial personal computer in advance, so that when the comprehensive monitoring system is subsequently replaced, the product configuration files do not need to be reconfigured, and the product configuration files can be directly read from the industrial personal computer.
For generating the external input data and the external excitation data in step 2, only one kind of data may be generated or both kinds of data may be generated according to actual requirements, which is not limited herein.
