Detailed Description
In order to make the implementation objects, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be described in more detail below with reference to the accompanying drawings in the embodiments of the present invention.
The invention relates to an automatic test method for a maximum takeoff weight look-up table value of flight control software, which aims to solve the problems of overlarge query quantity, overlong query time, low speed and easy error existing in the verification of the flight control software, and particularly provides an automatic test method for the maximum takeoff weight look-up table value, based on an automatic test system for the flight control software, wherein the automatic test system comprises a bus monitor and a test computer, the flight control software is arranged in the test computer and is used for managing the flight of an airplane, and the bus monitor is connected with the test computer and is used for monitoring the input and the output of the flight control software, and comprises the following steps:
firstly, a global variable database is established, the global variable database comprises navigation data containing airport names and airplane maximum takeoff weight data, the navigation data in the flight management software are stored in a table form in the establishing process, and the maximum takeoff weight data in the flight management software are also stored in the table form, so that the flight management software can be used conveniently when needed.
Then, the bus monitor monitors and obtains the airport number or name as the query condition parameter in the flight management software, so as to obtain the airport related information in the navigation data with the airport number or name as the query condition, which is the relevant new type of airport obtained by the fact that the departure airport inputted in the data input page of the flight management software in this embodiment is lxlxlxlxlx (the number corresponding to the airport name is customized in the database, such as LCJK corresponding to beijing airport, etc.), and the airport real-time parameter to be queried is inputted in the flight management software, and the airport real-time parameter is inputted in this embodiment: the wind speed is 10m/s, the flap configuration is 15 degrees, the temperature is 25 degrees, and finally the maximum takeoff weight calculation value is calculated by the flight control software, wherein the maximum takeoff weight given by the flight control software in the embodiment is 145.3 t.
Tables 1 and 2 are the maximum takeoff weight data of a certain airport information and real-time parameters in the navigation data, respectively.
TABLE 1 airport information in navigation data
TABLE 2 certain maximum takeoff weight data
Then, according to the query condition parameters on the flight management software monitored by the bus monitor, airport information in navigation data corresponding to the airport name query is obtained, and the input real-time parameters are queried in the airplane takeoff maximum weight data to obtain a maximum takeoff weight query value. In the embodiment, the airport running length of the airport with the airport number lxlxlx is 2500m, and the input real-time parameters are the flap 15 ° and the altitude is 0m, and the maximum takeoff weight query value corresponding to the temperature of 25 degrees at this time is 145.3 t.
And finally, comparing the calculated takeoff maximum weight value (145.3t) with the inquiry value (145.3t) of the takeoff maximum weight, if the calculated takeoff maximum weight value is equal to the inquiry value of the takeoff maximum weight, outputting that the test is passed, and if the calculated takeoff maximum weight value is not equal to the inquiry value of the takeoff maximum weight, outputting that the test is not passed.
In another embodiment of the present invention, when the temperature in the real-time parameters cannot match the maximum takeoff weight data, the real-time parameters such as the input airport are: the calculated maximum takeoff weight is 146t (the airport number is still LXXX) calculated by flight control software at the wind speed of 10m/s, the flap configuration of 15 degrees and the temperature of 23 degrees. And the maximum takeoff weight data is inquired at the moment, and the temperature is not 23 ℃. However, if the temperature of 23 ° falls within the range between the temperature of 20 ° and the temperature of 25 ° in the maximum takeoff weight data, and the corresponding maximum takeoff weight query value is (145.3t to 149.9t), it is considered that the calculated maximum takeoff weight value 146t given by the flight management software is "equal" to the lookup table value range of the maximum takeoff weight of 145.3 to 149.9t, and therefore the returned result passes the test.
In the invention, the process of establishing the database is to write a program to store the database which needs to be called subsequently, establish a global variable table, and store all the used tables into the global variable table, thereby facilitating the expansion of the functions later, only needing to enrich the content of the global variable table, and being capable of calling and storing data more quickly by establishing the global variable table.
In the process of monitoring the input in the flight management software by the bus monitor, when the data input by the pilot is called from the bus monitor, the called data is also stored in the global variable table, so that the search is convenient. Other parameters which are input by the pilot and are not needed when the maximum takeoff weight is searched are also stored, so that the subsequent function expansion is facilitated.
In the process of obtaining the maximum takeoff weight query value, when the median value of the corresponding data lookup table is searched, a method of gradually searching according to each parameter is adopted, and the range is gradually reduced according to different data. The specific form is that firstly, the flap is searched, the range of the corresponding flap value is reduced, then the next search is carried out in the range according to the altitude, then the run-out length is searched, the step is repeatedly carried out until the range is determined once according to all the parameters, and finally the maximum takeoff weight query value corresponding to the temperature is positioned.
The invention can be extended to the automatic test of the look-up table values of other functions, and can also program and write the calculation function when the verification of calculation is designed subsequently, and the numerical value is obtained and compared by calling and calculating the global variable table.
The automatic test method for the maximum takeoff weight lookup table value of the flight control software can automatically give a result in the maximum takeoff weight test of the flight control software test, so that the table lookup test is simple and convenient, the table lookup work of operators is avoided, and the method can be more rapid in multi-group data test and avoids errors.
The above description is only for the best mode of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
