Abstract:
    This invention relates to a terrane shift monitor including a shift sensor unit, an information collecting and processing unit, in which, the shift sensor unit includes: a shift wheel, a grating wheel, a grating sheet, a pull-up line and a tension unit, in which, the grating ring and the sheet are in the groove of a photoelectric coupler, the pull-up line windes the displacement wheel tightly, the output of the photoelectric coupler is connected with the input end of the information collection and processing unit composed of single-chip control, acoustooptic alarm, radio communication, RS485 communication and a supply conversion module, this monitor, a communication host and remote controller make up of a system, and the communication host can communicate with the PC, the monitor is fixed on the appearance terrane, the pull-up line is fixed on the internal terrane, its line displacement generates interference fringes by the relative movement of the two gratings to test the line displacement volume between terranes accurately to compute the change rate of the displacement.
