9. the control system of the auto-ultrasonic mold non-destructive detecting device according to claim 1~8 any one, special Sign is：The control system includes manual/auto switch unit, motor control unit, origin recognition unit, material tests list Member, the probe real-time recording unit of XY coordinates；

The manual/auto switch unit refers to be an externally input with a change-over switch, is signal acquisition center by PLC, Realize manual operation mode or automatic mode control；

The motor control unit refers to that center, motor are executive component in order to control with PLC, and PLC exports three group pulses, control The movement of tri- axis of XYZ drives probe to press continuous detection of the defined route in material surface cover type at the appropriate speed；

The origin recognition unit refers to be an externally input with XYZ limit switches, and PLC is in signal acquisition, conversion and output The heart, when one of limit switch is pressed, then where axis motor stop motion, when XYZ limit switches are pressed, i.e., For probe mechanical arm origin is returned in three axial directions；

The material tests unit includes no material tests module and edge of materials detection module；It is described to whether there is material tests mould Block refers to two second close switches that for inductor PLC is signal acquisition, conversion and output center, when material is in place When, two second are both turned on close to switch, the conducting of PLC corresponding input points, and when being activated with reference to automatic mode, which will be by It is automatic to start；

The edge of materials detection module is the intelligentized key of detection, is referred to four first close switches for inductor, PLC For signal acquisition, conversion and output center, in the non-edge detection of material surface, four first close to switch all in Conducting state is in off state when the edge for reaching material direction one, the first of corresponding direction one close to switch, and PLC is adopted Collect the signal, output pulse signal is controlled into motor, realize and drive probe in the positive direction (direction in the direction vertical with direction one Two) distance of a mobile probe diameter size, further, the negative direction toward direction one of popping one's head in continue to detect；

The probe real-time recording unit of XY coordinates refers to that using PLC as data processing centre motor drives for executive component and synchronizes Band is subjected to displacement, and under the premise of origin is identified, the absolute coordinate (XY coordinates) for opposite origin of popping one's head in is recorded in real time at PLC's Two data fields；Computer can read the two data fields by the communication between PLC, the real time position popped one's head in, knot The obtained ultrasonography of Z-direction of ultrasonic probe detection material is closed, three-dimensional visualization image that can be inside building material.

10. according to the detection controlling party of auto-ultrasonic mold non-destructive detecting device as described in any one of claim 1 to 9 Method, it is characterised in that：The detection control method is that equipment is powered, Z axis Aligning control, and in place, XY axis returns original to Z axis origin simultaneously Point, three axis origins are in place；Three axis origins in place+material put in place+manual switch is opened+and pressed start button (or three axis origins in place+material put in place+automatic switch open), Z axis movement, probe moves down, when any one First becomes conducting state, Z axis stop motion close to switch, if meeting except be located at X-axis negative direction, Y-axis negative direction first connects Nearly switch, other two first are both turned on close to switch, and X-axis movement is popped one's head in toward the movement of X-axis positive direction, when positioned at X-axis positive direction First disconnected close to switch, X-axis stop motion pops one's head in and the distance of a probe diameter size is moved toward Y-axis positive direction, then It pops one's head in toward the movement of X-axis negative direction, when the 4mm positioned at X-axis negative direction is disconnected close to switch, X-axis stop motion is popped one's head in toward Y-axis just The distance of a probe diameter size is moved in direction, then pops one's head in toward the movement of X-axis positive direction, so recycles, until in X-direction Two first close to switch, Y-axis positive direction first close to switch all in off-state, detection finishes.
