Information type data identification method and device

The invention provides an information type data identification method and device. When the method is executed, an input parameter, a calibration quantity and an output parameter are firstly configured; the input parameter comprises a to-be-identified array; then positioning and identifying the position of the special character in the array to be identified by using a calibration quantity; the effective array length of the output parameters is determined through the calibration quantity; obtaining an effective array in the to-be-recognized array according to the position of the special character in the to-be-recognized array, the length of the effective array and the position relation between the effective array and the special character; and finally, outputting the effective array. Therefore, even if the naming format of the to-be-identified array is changed due to software upgrading, the effective array in the changed to-be-identified array can still be identified. The effects that one version of software ca
