Embodiment

Below by specific embodiment, the present invention is further illustrated.

Accompanying drawing 1 is the Multi-core wire bending pick-up unit schematic diagram of the embodiment of the present invention, and figure comprises master controller 1, bending mechanism 3, bending angle setting device 2, tested wire rod 10-15, separate counts multi-thread core detecting unit 4-9.Wherein the concrete structure of the multi-thread core detecting unit of separate counts as shown in Figure 2, comprise the test side 210 of single-chip microcomputer 201, numeral method unit 202, LED indicating circuit 203, the common port 204 of Multi-core wire, each core shorted end 205, Multi-core wire, and realize the detection to Multi-core wire by the input of count signal 206, total reset signal 207, counting permission signal 208, local reset signal 209.

Master controller 1 presets bending number of times and frequency, in bending angle setting device 2, bending angle is set on the one hand after starting, and send signal to bending mechanism 3, when reaching the angle set by bending angle setting device 2, bending angle setting device 2 sends an angle arriving signal to master controller 1, reverse signal is sent to bending mechanism 3 after master controller 1 receives angle arriving signal, count signal is sent, so repeatedly until reach the bending number of times of setting to the backward separate counts of angle arriving signal process multi-thread core detecting unit 4-9 simultaneously; During not reaching the bending number of times of setting, master controller 1 sends counting to separate counts multi-thread core detecting unit 4-9 always and allows signal on the other hand, if there is clearing request period, also can send total reset signal to separate counts multi-thread core detecting unit.Another effect of bending angle setting device is whether the angle detecting bending in bending process reaches setting requirement.

Comprise 6 multi-thread core detecting units of separate counts in the present embodiment, altogether can realize simultaneously to the detection of 24 cores.

For tested Multi-core wire bending detection method as shown in Figure 3, concrete operation step is as follows:

The first step, start to detect 111, first detect master controller and whether have clearing request signal 112, if had, the time continuing about 3 seconds carries out detection 116 to reset signal, if still have clearing request signal after 3 seconds, then judge that this clearing request is effective, 117 are reset to available data and send numeral method 118; If master controller does not have clearing request signal, then detect local reset key and whether press 113, if there is local reset signal, the time continuing about 3 seconds carries out detection 116 to reset signal, if still have clearing request signal after 3 seconds, then judge that this clearing request is effective, 117 are reset to available data and send numeral method 118; If, do not perform second step;

Second step, if do not have clearing request signal, then whether have permission count signal 114, if not, return 112 and restart if detecting master controller; If had, carry out next step;

3rd step, carries out detection 115 to core break-make, if there is core obstructed, then indicates which root line out of joint 119, and terminates this time to detect, if all core passes through, then performs next step;

4th step, if detected by core, then determines whether count signal 121, if without count signal, returns 112 and restarts, if there is count signal, adds counting after 1, and send numeral method to existing number of times, and returning is 112 restart new detection.

Accompanying drawing 4 is embodiment circuit diagrams for independent multi-thread core count detecting unit.Following combined circuit figure does further statement.

The single-chip microcomputer model adopted in accompanying drawing 4 is STC15F204EA, and as shown in the figure, single-chip microcomputer receives total clearing request signal of autonomous controller by 21 pin, connects local reset key receive local clearing request signal by 17 pin; Once there is clearing request signal to occur, then continue to detect clearing request signal for 3 seconds, after 3 seconds, still have clearing request signal, then judge clearing request success, to sending digital pipe display circuit to show after zeroing data, wherein digital pipe display circuit is made up of U5, Q9-Q12, R38-R49; If there is no clearing request signal, judge whether master controller sends permission count signal by 20 pin, if counting allows invalidating signal, get back to beginning and repeat, if counting allows signal effective, by 7,8,9 pin, core break-make is detected; 7,8,9 pin upper ends are connected with+5V power supply respectively by the resistance of R52, R51, R50 tri-10K, and lower end is connected with three test leads respectively by the resistance of R59, R60, R61 tri-300 ohm; The three piece cores corresponding by known three test leads of accompanying drawing 2 form current return with the public core of another root (being ground connection) here after other end short circuit, if core is logical, what 7,8,9 pin were obtained by the electric resistance partial pressure of 10K and 300 ohm is low level, if core disconnects, what 7,8,9 pin received that+5V power supply obtains by 10K resistance is high level.As long as therefore judge the level height of 7,8,9 pin and the through and off of known core, if detect that 7 pin are high level, illustrate that the core corresponding with the test lead that R59 is connected disconnects, now light pilot lamp D5 by the defeated high level of 10 pin through R35; If detect that 8 pin are high level, illustrate that the core corresponding with the test lead that R60 is connected disconnects, now light pilot lamp D6 by the defeated high level of 11 pin through R36; If detect that 9 pin are high level, illustrate that the core corresponding with the test lead that R61 is connected disconnects, now light pilot lamp D7 by the defeated high level of 13 pin through R37; Three pin are all that high level illustrates it is that the disconnection of public core then lights D5, D6, D7 simultaneously in this way; If 7,8,9 pin are all that low level illustrates that core is all logical, now judge whether master controller has count signal to send over by 22 pin, then adding 1 to current data if any count signal send digital pipe display circuit to show, and repeats as then got back to beginning without count signal.
