Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model (after removing outer container 5 front panels);
Wherein, 1, light source, 2, ccd video camera, 3, lasing light emitter, 4, dividing plate, 5, outer container, 6, the shield machine wall, 7, shield duct piece.
Embodiment
As shown in Figure 1, the shield machine shield tail gap self-operated measuring unit based on vision-based detection described in the utility model comprises light source 1, ccd video camera 2, lasing light emitter 3, outer container 5 and the computing machine of image pick-up card is housed; Described light source 1 is fixed on the base of outer container 5, and ccd video camera 2 is fixed on the dividing plate 4 at outer container 5 middle parts, and lasing light emitter 3 is fixed on the madial wall of outer container 5; The output terminal map interlinking of ccd video camera 2 is as the input end of capture card; Outer container 5 is fixed on the shield machine wall 6.
Lasing light emitter 3 is two, is separately fixed on the outer box wall of ccd video camera 2 both sides.
In the shield machine construction process, can measure shield tail gap at any time, light source 1 provides enough brightness for the shield tail, constant distance between 3 two laser spots of lasing light emitter, beat at the edge of shield duct piece 7, the distance between these two laser spots is a foundation of calculating shield tail gap as a kind of demarcation; Ccd video camera is gathered shield tail image, and sends it to image pick-up card, and image pick-up card is a digital signal with the analog signal conversion of receiving, the related software that offers then in the computing machine is handled.
The control signal that data collecting card in the computing machine is used to gather supervisory control desk as the signal of " beginning to measure " etc., is used to start or stop measurement.
Shield tail calculation of Gap principle is as follows: computer software at first calculates two laser spots P1 of demarcation and the pixel between the P2, draw the relation between pixel and the actual range, utilize rim detection to calculate pixel between P1 and the shield machine wall and the pixel between P2 and the shield duct piece edge respectively then, distance b and d between them, the laser spots P1 of two demarcation and the distance between the P2 are known definite value c, so just obtain shield tail gap a=b-c-d.
With three shield machine shield tail laser measuring device for measuring described in the utility model, be installed to three diverse locations of shield machine wall 11, fix, the each measurement, obtain the numerical value in three shield tail gaps,, further judge the orientation of shield duct piece misalignment according to the size of these three numerical value.
With to result of calculation and the standard shield tail gap length of design compare, judge that it is whether in the shield tail interstice coverage of shield machine operate as normal, at last the data that calculate are passed to supervisory control desk, supervisory control desk adjusts accordingly shield tail gap according to actual conditions, reaches the real-time automatic measuring in shield tail gap.
