3) rocket testers need to have deeper understanding on software programs related to test launch control and have more solid programming experience to update the programs, and the requirements on the computer related professional ability of the testers are high.

Of course, in practical application, three devices may also be combined into one device or two devices, and the setting may be performed according to actual requirements, which is not limited in this embodiment of the present invention.

In the above application environment, a telemetry data resolving method may be performed, as shown in fig. 3, the method including:

step S301, when the telemetering data of the rocket is obtained, corresponding first resolving description information is obtained based on a first parameter code in the telemetering data;

after receiving the telemetry data of the rocket sent by the telemetry equipment, the resolving equipment can match the first parameter codes in the telemetry data to obtain corresponding first resolving description information.

Step S302, a first resolving formula in the first resolving description information and first parameter data in the telemetering data are verified;

after the matched first calculation description information is obtained through matching, in order to ensure the accuracy of subsequent calculation, a first calculation formula in the first calculation description information and first parameter data in the telemetering data need to be checked respectively.

Step S303, when the first calculation formula and the first parameter data are checked to pass, calculating the first parameter data by adopting the first calculation formula to obtain a first calculation result;

In the embodiment of the invention, when the telemetering data of the rocket is acquired, corresponding first resolving description information is acquired based on a first parameter code in the telemetering data, then a first resolving formula in the first resolving description information and the first parameter data in the telemetering data are verified, when the first resolving formula and the first parameter data are both verified, the first resolving formula is adopted to resolve the first parameter data to obtain a first resolving result, and when the first resolving description information comprises a standard data comparison table, the first resolving result is interpolated based on the standard data comparison table to obtain a second resolving result. Through the mode, the embodiment of the invention abstracts the resolving process of the telemetering data of the carrier rocket, realizes the uniform description of the resolving process through the resolving formula and the standard data comparison table, and enables a tester to complete various configurations of the resolving process through descriptive words instead of program codes. Meanwhile, due to the fact that descriptive characters are visual and easy to understand, testers without program code bases can also quickly master the configuration method, and configuration efficiency of the calculation process is greatly improved. Moreover, the descriptive characters which are intuitive and easy to understand are adopted, so that the difficulty of error checking is greatly reduced when the configuration is checked, and the error checking efficiency is improved.

A telemetry data resolving method may also be performed in the application environment shown in fig. 2, as shown in fig. 4, the method comprising:

step S401, acquiring at least one preset candidate resolving description information;

specifically, the solution device may obtain preset at least one candidate solution description information from the terminal, where the candidate solution description information is the solution description information that has been edited.

In practical application, an application program for editing the calculation description information by a user may be installed in the terminal, and the user may edit the calculation description information through the application program and send the edited calculation description information to the calculation device, or the user may directly edit the calculation description information on the calculation device through the application program, or of course, the user may edit the calculation description information in other manners, so that the calculation device may finally obtain the candidate calculation description information, and the candidate calculation description information may be set according to actual requirements, which is not limited in the embodiment of the present invention.

Step S402, at least one candidate resolving description information is verified, and at least one second resolving description information passing the verification is obtained;

since the calculation description information is the basis for calculating the telemetry data, the accuracy of the calculation description information needs to be ensured, otherwise, the telemetry data cannot be calculated under the condition that the calculation description information is wrong. Therefore, after at least one candidate resolving description information is acquired, each candidate resolving description information can be verified, if the verification is passed, subsequent resolving is executed, if the verification is not passed, resolving is terminated, and at least one second resolving description information which is passed is obtained.

In one embodiment of the invention, any candidate resolving description information comprises a candidate parameter code, a candidate resolving formula, a candidate standard data comparison table and a candidate return type;

detecting whether the candidate resolving formula is legal or not;

it is detected whether the return type is correct.

Specifically, when checking each candidate solution description information, the checking includes, but is not limited to:

1) detecting whether the candidate parameter codes are correct; for example, if a parameter code in the candidate solution description information is "Connand" and the correct parameter code should be "Command", it may be determined that the parameter code is wrong;

2) detecting whether the candidate resolving formula is legal or not; specifically, whether the grammar of the calculation formula is correct or not can be detected, and whether elements such as functions, variables, operators, brackets and the like in the calculation formula are legal or not can be analyzed;

3) detecting whether the candidate standard data comparison table exists or not and whether specified column information exists in the candidate standard data comparison table or not; specifically, whether the description of the standard data lookup table is included in the solution description information, that is, whether the "config" attribute exists, if so, whether the standard data lookup table corresponding to the config exists, and if not, it may be determined that the candidate solution description information is incorrect. For example, if a config attribute exists in a certain candidate solution description information and config = "wdca. csv:1", but no "wdca. csv" file is found through detection, it can be determined that the candidate solution description information is wrong;

4) detecting whether the return type is correct; for example, if a certain return type in the candidate solution description information is "signaled short" but the correct return type should be "double", it may be determined that the candidate solution description information is incorrect, or if a certain return type in the candidate solution description information is "double" but the correct return type should be "double", it may be determined that the candidate solution description information is incorrect.

In the embodiment of the invention, when detecting that at least two second parameter codes are the same, generating the alarm information.

Specifically, when it is detected that at least two second parameter codes are the same, the warning message may be generated, and the user is prompted to modify the warning message until the same second parameter codes do not exist, and the warning message is cancelled. The same second parameter code may be in the same candidate solution description information or in different candidate solution description information, which is not limited in this embodiment of the present invention.

Step S403, generating a resolving description information base by taking a second parameter code of each second resolving description information as a keyword, and storing the at least one second resolving description information in the resolving description information base;

after at least one second resolving description information is obtained, a resolving description information base can be generated, each second resolving description information is stored in the resolving description information base, the parameter code corresponding to each second resolving description information is used as a keyword, and the keyword can be used for matching the parameter code during subsequent retrieval.

Step S404, when the telemetering data of the rocket is obtained, corresponding first resolving description information is obtained based on a first parameter code in the telemetering data;

In one embodiment of the present invention, obtaining corresponding first solution description information based on a first parameter code in telemetry data includes:

matching the first parameter codes in the telemetering data with each second parameter code in the resolving description information base;

Specifically, a first parameter code may be extracted from the telemetry data, and then the first parameter code may be matched with each second parameter code (i.e., each keyword) in the generated solution description information library, and if a target second parameter code is matched, the second solution description information including the target second parameter code may be used as final solution description information; if the matching fails, the solution is terminated.

Step S405, verifying a first resolving formula in the first resolving description information and first parameter data in the telemetering data;

In one embodiment of the present invention, verifying the first solution formula in the first solution description information and the first parameter data in the telemetry data includes:

detecting whether the first resolving formula is legal or not;

it is detected whether the number of bytes of the first parameter data exceeds the number of formal parameters in the first solution formula.

Specifically, the checking may include:

1) detecting whether the first resolving formula is legal or not; specifically, information such as a function, an operator, a bracket, a form parameter and the like in the first calculation formula is obtained, and then whether the information such as the function, the operator, the bracket and the like is legal is detected, for example, whether the bracket is closed, whether undefined characters exist or not and the like are detected, and whether the form parameter is X1-X8 or not are detected. If one item fails, the first solution formula can be judged to be illegal;

2) detecting whether the number of bytes of the first parameter data exceeds the number of form parameters in a first resolving formula; specifically, since the number of form parameters is set in advance, the number of form parameters in the first calculation formula is fixed without modification, and therefore, it is possible to detect whether the number of bytes of the first parameter data exceeds the number of form parameters in the first calculation formula, and if so, it is possible to determine that the detection is passed, and if not, it is possible to determine that the detection is not passed. For example, if the number of bytes of the first parameter data is 6, and the formal parameters in the first solution formula are X1, X2, X3, and X4, it is determined that the detection is passed; if the number of bytes of the first parameter data is 3 and is less than the number of the form parameters 4, the calculation cannot be executed, the detection is determined not to pass, and the calculation is terminated.

Step S406, when the first calculation formula and the first parameter data are checked to pass, calculating the first parameter data by adopting the first calculation formula to obtain a first calculation result;

In the embodiment of the present invention, calculating the first parameter data by using a first calculation formula to obtain a first calculation result, includes:

resolving each actual parameter by adopting a first resolving formula to obtain a resolving result;

Specifically, the first parameter data may be filled into each formal parameter in the first calculation formula to obtain each actual parameter, then the first calculation formula is executed to calculate each actual parameter to obtain a calculation result, and then the calculation result is converted into the first return type in the first calculation description information, so as to obtain the first calculation result.

For example, the "star-arrow separation 1 state" is solved, the obtained solution result may be 1 or 0, and it can be known from table 1 that the return type of the "star-arrow separation 1 state" is "signed char", and then the solution result is converted into signed char, so as to obtain a first solution result.

Wherein the following features are specified when executing the solution formula:

1) if the splicing function exists in the formula, the splicing function has the highest calculation priority;

2) splicing a plurality of byte data of the parameter data to a continuous memory in sequence, and then forcibly converting the byte data into a corresponding data type;

3) if the bracket exists in the formula, firstly carrying out the operation in the bracket and then carrying out the operation outside the bracket;

4) when a plurality of operators are parallel, the operation priority is as follows from high to low: bit operators, arithmetic operators, boolean operators;

5) when the operators are parallel to the priority operator, the operations are performed according to the operation sequence from left to right.

Step 407, when the first calculation description information includes the standard data comparison table, performing interpolation processing on the first calculation result based on the standard data comparison table to obtain a second calculation result.

In the embodiment of the present invention, interpolating the first calculation result based on the standard data comparison table to obtain the second calculation result includes:

and performing interpolation calculation on the candidate standard value based on the candidate comparison value and the first calculation result to obtain a second calculation result.

Specifically, when the standard data comparison table attribute is detected to exist, the corresponding standard data comparison table is obtained, the data standard value of the 1 st column in the standard data comparison table and the comparison value of the target column are obtained, then the candidate standard value and the candidate comparison value which are adjacent to the first calculation result in the standard data comparison table are obtained, and then interpolation calculation is carried out on the candidate standard value by adopting the candidate comparison value and the first calculation result to obtain a second calculation result.

For example, it is assumed that "config = 'wdca. csv: 2'" is included in certain first solution description information, the first solution result is 0.35, and the standard data comparison table is table 1. When it is detected that the first solution description information includes a config attribute, acquiring a standard data comparison table with a file name of Wdca.csv, acquiring a data standard value of a 1 st column and a comparison value with a column serial number of 2 (a 3rd column) in the standard data table, then acquiring a candidate standard value and a candidate comparison value which are adjacent to 0.35 from the 1 st column and the column serial number of 2 in the table 1, wherein the candidate standard value and the candidate comparison value are respectively '3', '4', '0.343' and '0.355', then performing interpolation calculation on the candidate standard value by using the candidate comparison value and the first solution result to obtain a calculation result, and then converting the calculation result into the return type according to the return type in the first solution description information to obtain a second solution result. Such as: 3+ (4-3) (0.35-0.343)/(0.355-0.343) =3.583, i.e., 3.583 is the second solution result.

It should be noted that the interpolation calculation is a linear interpolation algorithm, and in practical application, other interpolation algorithms are all applicable to the embodiment of the present invention, and may be set according to practical requirements, which is not limited in this embodiment of the present invention.

Further, generally, the number of the adjacent candidate standard values is 2, but when the position of the first solution result is the first or last one, the number of the adjacent candidate standard values is 1, and then the standard value is directly taken as the final solution result at the time of calculation.
