Embodiment
Below in conjunction with drawings and Examples, technical scheme of the present invention is described further.
On figure of the present invention, amount reads chi primarily of Fig. 1-center of circle through hole and the straight vertical radial line by the center of circle, Fig. 2-magnetic bearing, coordinate direction angle, angle of circumference, Fig. 3-grade rod, Fig. 4-checked spun antung coordinatometer, Fig. 5-demarcation coordinate parallel lines auxiliary scale, the compositions such as Fig. 6-1:25000,1:50000,1:100000 accurate coordinates measure chi, Fig. 7-nylon wire chi.On figure of the present invention, the accurate coordinates of the different proportion that amount is read in chi measures chi, adopts checkering design, respectively with the parallel placement of circle chi diameter line; Nylon wire chi adopts the nylon wire of 0.5 millimeter, and its line is through the center of circle, and joint button slip-off preventing is stamped at two ends, line length 50 centimetres; On chi, various lines all adopt the method for printing to realize.
The present invention now uses figure chi primarily of Fig. 8-north arrow chi, and Fig. 9-parallel ruler, bar demarcated by Figure 10-ground object target direction line, the compositions such as Fig. 9-centimeter scale chi.The present invention now parallels with the long limit of square chi by the north arrow North and South direction in figure chi; The vertical edges of parallel ruler when drawing in, itself and main scale near, and length is concordant; Ground object target direction line is demarcated bar and is adopted aluminum metal screw to carry out degree of tightness control with main scale junction, and two demarcates bar on same straight line when guaranteeing use, and with main scale plane being perpendicular.
As shown in Figure 7, on figure, amount reads chi when realizing that on figure, certain impact point accurate coordinates amount is read, amount on figure being read the chi center of circle to be placed in impact point in the heart, utilizing the grid bearing on chi to demarcate auxiliary scale makes on chi two vertical diameters parallel with the coordinate co-ordination on figure, can measure the accurate coordinates reading impact point; On figure, amount reads chi when measuring the position angle in interpreting blueprints between certain point and another impact point, then first demarcate grid bearing at certain point, angle zero line on ruler limit is paralleled with the coordinate ordinate of figure, then, utilize nylon wire chi to be connected with impact point straight line by certain point, then hand over to paint at straight line and ruler border and locate direct reading; On figure, amount reads chi when realizing on figure the checked spun antung coordinate recognition of certain point, certain section of terrain slope interpretation, certain line segment length by centimetre metering actual range, then the correlative on ruler directly can be utilized to read chi and directly measure calculation or interpretation.
As shown in Figure 10, now with figure chi when realizing on figure certain point with existing this direction line test, then first utilize and now demarcated map with the north arrow on figure chi main scale, this main scale to be moved on figure near certain point, demarcation bar on this main scale is become plumbness, then, the center of now certain point is aimed at eyes, and make two demarcation bars with now certain point center point in alignment, mobile now with the auxiliary chi of figure chi again, the central point of chi limit and figure certain point upper is pressed mutually, finally utilizes this auxiliary chi centimeter scale chi to draw straight line.
Patent of the present invention, innovative point is many, integrated level is high, multiple functional, accuracy is good, with two rulers, can realize scheming upper rapid measuring and read various data, interpretation terrain slope, map orientation magnetic north direction, the direction line now accurately surveying and drawing certain point, the deflection of comprehensive direct amount interpreting blueprints above between certain 2, the amount of comprehensively meeting on topography figure is read and now uses figure to the application demand of instrument, solve in decades on topography figure amount read with now various with figure use instrument, carry the practical problemss such as inconvenience, operating speed is slow, degree of accuracy is low.
