However, the huge ICD information can not be entered by manual work to meet the project requirements. Although the ICD of some projects can be generated through the ICD configuration management tool, there are a large number of discrete information in the bus signal, which often represents different parameter meanings through different numerical values. When filling in the ICD, the filling of numerical values and parameter meanings often has no unified standard, resulting in many errors and exceptions when using automatic tools to enter ICD information and convert it into signal source configuration, which requires a lot of effort to correct.

[0018] This application provides a flight parameter bus data signal source configuration system.
[0019] like Figure 1 As shown, a flight parameter bus data signal source configuration system includes: The detection unit is used to detect whether the discrete information string meets the required template.
[0020] The configuration unit identifies the discrete information strings conforming to the template and splits each discrete information string according to the template, and saves the numbers and state description information in the number set and the state description information set respectively for calling by the signal source software.
[0021] The correction unit extracts features from the discrete information strings not conforming to the template, and distinguishes the numbers and state information, and saves them in the number set and the state description information set respectively for calling by the signal source software.
[0022] The detection unit extracts the signal definition and description part in the ICD file using the ICD configuration management tool to generate an EXCEL file.
[0023] The correction unit corrects the discrete information strings in the EXCEL file, the configuration unit saves the corrected discrete information strings in the form of an XML file in the local, and uses the XML file as the configuration file of the signal source software. The user can use the signal source software by copying the XML file into the signal source software.
[0024] Suppose a set of discrete information needs to be represented by 0~255, and the information name represented by each number is: state description information 0, state description information 1, …… state description information 255. First, fix a discrete information string template that can be correctly recognized by a signal source software as follows: "0: state description information 0, 1: state description information 1, 2: state description information 2, …… 255: state description information 255".
[0025] The detection unit detects the errors of the discrete information strings by the method of regular expression, and the error categories include: inter-word symbol missing, intra-word symbol missing, and intra-word symbol error.
[0026] The correction unit uses a comma to split the discrete information strings with inter-word symbol missing; for example, 0: state description information 0 1 state description information 1 02 state description information 2 …… 255 state description information 255. At this time, only the numbers and state description information in the discrete information strings need to be extracted, and the numbers and state description information are saved in the number set and the state description information set respectively for calling by the signal source software.
[0027] The correction unit performs the following operations on the discrete information strings without inter-word symbol missing: For the discrete information strings with intra-word symbol missing, such as 0 state description information 0, the correction unit extracts the first number in the string by regular expression, and adds ":" between the first number and the following string, taking ":" as the separator.
[0028] For the discrete information string with in-word symbol error, the correction unit extracts the first given punctuation symbol in the discrete information string as a delimiter by using regular expression; for example, "0=state description information 0", "0: state description information 0", "0- state description information 0", "0 state description information 0", ": 0 state description information 0", "0~n: state description information", and the punctuation symbol in the substring is extracted, because the punctuation symbol may exist in "state description information", and therefore, only the first matched punctuation symbol is used as a delimiter to further divide the substring into "0" and "state description information 0".
[0029] The correction unit extracts the number and state description information before and after the delimiter in the discrete information string by using regular expression, and saves the number and state description information in a number set and a state description information set, respectively, for calling by signal source software.
[0030] For the discrete information string with correct inter-word symbol and in-word symbol and the number being 0-n, the number part is divided by using "-", the value of "n" after division is obtained, and through loop assignment, "0-n: state description information" is divided into identifiable "0: state description information", "1: state description information",..., and "i: state description information", where i is 2 to n.
[0031] Through the above method, the problem that the signal source configuration tool appears abnormal and fails to parse the discrete information string due to non-standard and non-uniform filling can be eliminated, and manual correction can be avoided, and the signal source configuration automation degree and efficiency can be improved.
[0032] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
