Description
Technical Field
The invention belongs to the technical field of information query, and particularly relates to a calculation tool for checking data word messages and a calculation method thereof.
Background
The GJB1188A-1999 aircraft hangar electrical connection system interface requirement sets forth a checksum requirement for data word messages: when each data word in the message (containing the checksum) is circularly right shifted and each bit of the shifted data words is summed (not carried) using a modulo-2 algorithm, it should be 0. The method for circularly moving right comprises the following steps: a certain data word is right shifted by a number of bits equal to the number of words of the data word preceding it in the message, i.e. the first word is not shifted, the second word is shifted one bit to the right in a cycle, the third word is shifted two to the right in a cycle, etc. As data word message one: 0001 c 0000 f 001 e0b (checksum); data word message two: 123456789 abc def 0000082 f0 (checksum). When testing data messages of the protocol, various message coverage protocol contents need to be generated, each message needs to calculate a checksum, and the checksum is calculated in a manual mode, so that the efficiency is low and errors are easy to occur.
Disclosure of Invention
In order to solve the above problems, the present invention provides a calculation tool for data word message verification, comprising an input unit, a processing unit, a verification calculation unit, and a display unit; the input unit is used for inputting data word messages, and the data word messages are hexadecimal; the processing unit converts the data word message into a decimal message word array; the check calculation unit calculates the check sum of the message word array according to a check sum calculation method; the display unit is used for displaying the calculation result of the message word array checksum.
Preferably, the data word message has a length that is an integer multiple of a word.
A method of computing a computational tool for data word message verification, comprising the steps of:
s1: inputting the data word message on an input unit;
s2: the word processing unit carries out word conversion processing on the data word message and outputs a message word array;
s3: the check calculation unit calculates the check sum of the message word array;
s4: the result of the checksum is displayed by the display unit.
Has the advantages that: when the method is used for testing data messages, various message coverage protocol contents can be generated, each message can be subjected to checksum calculation, and the method is higher in efficiency and less prone to errors than the method for calculating the checksums in a manual mode.

Preferably, the data word message has a length that is an integer multiple of a word.
The specific principle of the calculation tool is as follows: a data message word is input from the input unit, wherein the data word message in hexadecimal representation has a message length which is an integer multiple of the word, i.e. 4 times the hexadecimal character, e.g. 1234H. The word processing unit converts hexadecimal words into an array of decimal representative message words. And the check calculation unit calculates the check sum of the message word array according to a check sum calculation method. The checksum calculation method is a known calculation method. And finally, outputting the checksum calculation result to a calculation result display unit in a text form.
A method of computing a computational tool for data word message verification, comprising the steps of:
s1: inputting the data word message on an input unit;
s2: the word processing unit carries out word conversion processing on the data word message and outputs a message word array;
s3: the check calculation unit calculates the check sum of the message word array;
s4: the result of the checksum is displayed by the display unit.
When the calculation tool is used for testing data messages, various message coverage protocol contents can be generated, the checksum calculation is carried out on each message, and the efficiency is higher than that of calculating the checksum in a manual mode and errors are not easy to occur.
The above embodiments are not limited to the technical solutions of the embodiments themselves, and the embodiments may be combined with each other into a new embodiment. The above embodiments are only for illustrating the technical solutions of the present invention and are not limited thereto, and any modification or equivalent replacement without departing from the spirit and scope of the present invention should be covered within the technical solutions of the present invention.
