The invention is suitable for the technical field of engineering construction elevation and provides a numerical control elevation instrument, an elevation system and a construction elevation measurement method. When in use, after a laser head of a geoplane is adjusted to be horizontal, a single laser is emitted and reaches a scale mark on the front side of an instrument cover of the numerical control elevation instrument, measurement personnel read an indicating value of the scale mark at this time and then input the indicating value into a mobile terminal, a moving value of a pointer of the numerical control elevation instrument is calculated by the mobile terminal according to the indicating value and by combining stored subgrade coordinate parameters, lifting parameters and the like, then the moving value is sent to the numerical control elevation instrument, and a driving motor is controlled to operate by a controller of the numerical control elevation instrument, so that the pointer is controlled to reach an indicating position. The elevation instrument has the advantages of simplicity in operation and rapid response, and an elevation point can be accurately and quickly found.
