The circuit of the utility model horizontal metroscope is as shown in Figure 5: the RD of single-chip microcomputer 31 ₀～RD ₃As line output line, RA ₀～RA ₂As the row incoming line, constitute 4 * 3 keyboard matrixs, by keyboard 32 operations, send to start and measure, finish, orders such as time-out are printed in inquiry.Memory 33 adopts has I ²The EEPROM of C bus, its SCL, SDA respectively with the RB of single-chip microcomputer 31 ₆, RB ₇Link to each other; The RC of single-chip microcomputer 31 ₀～RC ₇Link to each other the RB of single-chip microcomputer 31 as data bus with the data line of real-time timepiece chip 34 with printer 36 ₅, RB ₄, RB ₃, RB ₂Link to each other with CS, AS, R/W, the DS of real-time timepiece chip 34 respectively; The RB of single-chip microcomputer 31 ₁As the STB control end of printer 36, the RA of single-chip microcomputer 31 ₄, RA ₅Respectively as the ACK of printer 36, the BUSY signal input part; Also be connected to LCD 35 and count pulse and direction identification circuit 37 on the single-chip microcomputer 31.

Use the utility model to survey the length of a volume electric wire, at first adjusting screw 28, make pillar sleeve 27 along pillar 26 oscilaltions, make the total height of pillar be higher than the height for the treatment of test coil, again tested cable 25 is placed on the draw drum 1, unclamp nut 30, mobile pull plate 29 drives pillar 26 and radially moves, tighten the cable inner ring after, unscrew nut 30, extract the end of a thread out and pass directed cylinder 3, between contact roller 5 and counter wheel 4, pressed, the end of a thread is fixed on the take-up reel 6, draw drum 1 is enclosed within the axle of wire-unfolding rack 2 and goes up and can rotate flexibly, shakes rocking handle 7 drive cables and is wrapped on the take-up reel 6.Because contact roller 5 is along with shifting axle 18 presses counter wheel 4 at spring 15 through playing post 14, keep certain elastic pressure, when cable passes through between contact roller 5 and counter wheel 4, because friction force effect, drive counting crop rotation circular motion, the shading code-disc 9 that is contained on the shaft coupling 11 that fixes with counter wheel 4 rotates in the groove of photoelectric sensor 10, produce counting and cable direction of motion signal and be sent to horizontal metroscope, handle the generation two pulse signals through horizontal metroscope, the length of cable that each pulse is corresponding certain, thereby the length that will detect cable becomes the umber of pulse of surveying circular motion, the two pulse signals of photoelectric sensor 10 outputs, after count pulse and 37 processing of direction identification circuit, count signal is sent to the RB of single-chip microcomputer 31 ₀, the direction of motion signal is sent to the RA of single-chip microcomputer 31 ₃Promptly at the RB of single-chip microcomputer 31 ₀On when the upper edge saltus step occurring, according to single-chip microcomputer 31RA ₃Level be high or low difference, length value is added or subtracts the length of a pulse correspondence; LCD 35 shows that real-time measuring data, measurement finish the back printer prints and go out measurement result, detects data such as date.

The utility model length measurement precision height both can fixedly mount use, and also available cyclecar is transported to the scene and detects, and for this reason, can be widely used in technical supervision, and departments such as commodity inspection check the length of rolling electric wire.
