Method and system for automatically collecting effective drilling data of drilling machine

The invention provides a method and a system for automatically collecting effective drilling data of a drilling machine. The method comprises the following steps: analyzing each sub-process of drilling of the drilling machine; on the basis of the built drilling-while-drilling measurement system of the drilling machine, determining a drilling-while-drilling parameter threshold value of each sub-process of drilling of the drilling machine; if the while-drilling parameters change in the normal working range, it is judged that the while-drilling parameters are effective drilling data, and the effective drilling data are stored and output; otherwise, directly rejecting; according to the scheme provided by the invention, the invalid data can be automatically removed according to the preset logic program, and only the effective drilling data is stored, so that the effective drilling data acquisition of the drilling machine is effectively improved, the acquisition efficiency is improved, and the labor intensity of wo
