Digital twist detector for twist machine

The utility model relates to a kind of two-for-one twister twist digital test machine, is a kind of automatic detection instrument.

The two-for-one twister twist digital test machine that China is present comprises that numeral shows, ingot speed phonic wheel and sensor, linear speed phonic wheel and sensor thereof because the frequency input signal excursion is bigger, employing be conventional digital circuit.Each content of parameter shows, upgrades and need just can finish once in 10 seconds at every interval, the parameter that has shows has only utilized two in the group of four figures, the demonstration conversion of the twist, ingot speed, linear speed needs manually could realize that this just makes, and certainty of measurement is low, response speed is slow, inconvenient operation.

The purpose of this utility model is: this detector is improved, make its each parameter show, upgrade required time and reduce at interval, the twist, ingot speed, linear speed Display Realization are changed automatically.

Below in conjunction with accompanying drawing the technical solution of the utility model is described.

Fig. 1, the utility model external structure schematic diagram.

Fig. 2, the utility model structure principle chart.

Such as Fig. 1, Fig. 2, the utility model comprises band auto-lock function switch (4), charactron (5), linear speed phonic wheel (8) and the linear speed phonic wheel sensor (7) on ingot speed phonic wheel (1) and ingot speed phonic wheel sensor (2), casing (3), the panel (6), adopt 8031 SCM systems in the casing, in succession photoelectrical coupler (15), (16) of sensor (2), (7) are connected to NAND gate (20) input, and NAND gate (20) is connected on 8031, the interface P of single-chip microcomputer (9)_1.5、P _1.7End, 8031 SCM systems comprise: 8031 single-chip microcomputers (9) and 8155I/O chip (10), level shifting circuit are connected on 8031 single-chip microcomputers (9) interface P_1.0End, 74LS139 decoder (11) and 8031 single-chip microcomputers (9), 8155I/O chip (10), 74LS2764 read-only memory (12) links to each other, 74LS90 counter (13) links to each other with 74LS373 latch (14) with 8031 single-chip microcomputers (9), read-only memory (12) and latch (14) docking, read-only memory (12) and latch (14) are connected on 8031 single-chip microcomputers (9) and the 8155I/O chip (10) by bus (21), electrify restoration circuit is connected on 8031 single-chip microcomputers (9), on the external reset end RST of 8155I/O chip (10), three output lines of 8031 single-chip microcomputers (9) are connected on three light emitting diodes (22) by 74LS07 buffering driver (17), (23), (24) on, the output line of 8155I/O chip (10) is by 74LS07 buffering driver (17), (18) be connected on the charactron (5), the output line of 8155I/O chip (10) is connected on the triode by 74LS06 buffering driver (19), and triode links to each other with charactron (5). Operation principle is: the working procedure that weaves is solidificated on the read-only memory (12), produces a positive pulse by electrify restoration circuit at the reset terminal RST of 8031 single-chip microcomputers (9) and 8155I/O chip (10) after the energising, start working after making 8031 single-chip microcomputers (9) enter original state. Carry out one by one the programmed instruction that is solidificated in the read-only memory (2) by start element, make the utility model under programme-control, automatically finish measurement, calculating, regularly, the work such as demonstration, ingot speed, linear speed signal are at 8031 single-chip microcomputer I/O end P_1.0、P _1.5、P _1.7Automatically finish ingot speed, linear speed measurement conversion under the control, the ingot speed or the linear speed signal that are strobed are sent to INT₀--the external interrupt input, send interrupt requests to main frame. Open counter T after the response of host interrupt requests₁The counting door, begin to measure by single-chip microcomputer (9) ALE The standard clock signal through counter (13) of end output. Work as INT₀When end was received the linear speed signal for the second time, main frame stopped counting, at this moment, and T₁The calibration pulse number of middle accumulative total namely reflects tested ingot speed, linear speed signal period numerical value. After finishing ingot speed, linear speed signal measurement, the show value that main frame carries out a series of calculating, changes, draws ingot speed, linear speed, the twist recording numerical value. After 8155I/O chip (10) output again through six buffering driver 74LS07(17), (18), six anti-phase buffering driver 74LS06(19) drive, control LED charactron (5) shows after amplifying. Operation by to band auto-lock function switch (4) changes 8031 single-chip microcomputers (9) P_1.0The level state of end, single-chip microcomputer detects P by inquiry mode_1.0The height of level, and according to P_1.0It is the fixing present displayed content that shows that the height of end level decides, or circulation shows the twist, ingot speed, linear speed parameter. 74LS139 decoder (11) is used for controlling 8155I/O chip (10) among the figure, and the duty of read-only memory (12).

The utility model has the advantages that: the demonstration of the twist, linear speed, ingot speed conversion is by the Single-chip Controlling automatic cycle, and each parameter is upgraded per 1 second and just carried out once, has improved certainty of measurement.
