Abstract

The invention discloses a network protocol data detection method and device. The network protocol data detection method comprises the steps of acquiring a to-be-detected signal; according to the to-be-detected signal, calculating a maximum theoretical value and a minimum theoretical value of the to-be-detected signal; acquiring an actual maximum value and an actual minimum value of the to-be-detected signal; and if the actual maximum value is different from the maximum theoretical value, changing the actual maximum value to the maximum theoretical value; and if the actual minimum value is different from the minimum theoretical value, changing the actual minimum value to the theoretical minimum value. The problem of network protocol data errors due to operation errors of designers is solved.

Description

technical field [0001] The invention relates to the technical field of network protocol file detection, in particular to a network protocol data detection method and device. Background technique [0002] In the actual project implementation process, developers will make mistakes when writing network protocol DBC documents, such as writing the upper limit of the temperature signal message as 206 (actually should be 207), when hardware-in-the-loop (HIL, hardware-in-the-loop) ) When the test equipment invokes the DBC, it can only send 206 signals due to the upper limit of the signal, which will cause the test software to identify errors, affect the test progress, and increase the project risk. [0003] At present, the problem of errors when writing the DBC is a common problem. The designer may make human errors when making the DBC, and write wrong information such as data upper limit, lower limit or variable name, which will affect subsequent testing and calibration. .
