Specific embodiment:
At first to prepare a steel cord that the part fracture of wire is arranged, be fixed in the centre of six disks, in fixation procedure, to keep steel cord linear state not to be bent, fixing effect will make the steel wire can transverse movement but be difficult for lengthwise movement, and guarantees that six disks can rotate with its pulling.
Sensor is contained in appointed positions, about about 1 centimetre of adjustment sensor to the distance of steel wire, distance is adjusted needn't be very accurate, and the back can adjust according to actual conditions again.With in the sensor alignment steel wire good one section.In the border circular areas of sensor, steel wire must be wound with two sections at least.
The operation that begins to power on after power supply connected, the normal condition when powering on operation is that power light is lighted, and dual-colored LED is all lighted subsequently earlier and is extinguished, and relay is not beated.Whether will pay special attention to watch power light bright when therefore powering on, whether dual-colored LED is for bright entirely, whether relay has is beated.
Subsequent is a step of most critical in the debug process---adjust.Step is as follows:
One, presses the knob of adjusting (button of adjusting is No. 1 knob of aluminium box top) earlier, can both hear the ticktack of relay at every turn after pressing, wait and see that No. 2 pilot lamp have flicker back release button.
Two, with one section that fracture of wire is arranged in the sensor alignment steel wire, press the button of adjusting, hear release button behind the sound that relay beats.
Three, mobile steel wire with in the sensor alignment steel wire good one section, is pressed the button of adjusting, and hears release button behind the sound that relay beats.
If four adjust successfully, pilot lamp can extinguish after being spaced apart 1 second flicker three times.The failure if adjust, pilot lamp can extinguish after the fast blink.
Five, the adjust possible cause of failure is that the sensor distance steel wire is far away excessively, and should adjust distance this moment, makes sensor more near steel wire, advances to adjust again then.
Adjust after the end, should spur steel wire once more, observe at the fracture of wire place whether to produce warning (alarm condition is that two redness appear in LED, and No. 3 relays become off-state), also should not adjust again if produce warning at the fracture of wire place.
The situation of failure if adjusting appears in continuous several times, whether the putting position that then should preferentially detect the steel cord is correct, if not then needs more emat sensor, perhaps changes circuit board.
Adjust finish after, sensor detects the guiding principle cord, the output two paths of signals, wherein one the tunnel is digital signal, the affirmation of be used to adjust success and failure.Another road is a simulating signal, i.e. the detection signal of steel cord.Because the signal of sensor can not allow the single-chip microcomputer Direct Recognition, therefore need add signaling conversion circuit at front end.Signal processor, the signal that the signal that obtains after the conversion is set when before having adjusted relatively, when finding that the current twist is reduced to a certain degree, system can light alarm lamp 1, the twist of the steel wire that the prompting user produces descends to some extent, but still within acceptable ranges.When the twist continued to reduce, system can light alarm lamp 2, and the prompting user twist descends serious, at underproof edge.Occur as fracture of wire, system can light wrong pilot lamp, and the steel wire of reminding the user to produce at present is a substandard product, and starting relay stops the operation work of whole production equipment simultaneously.Three alarm set points of this system all have the audio alert function.
Signal processor is sent to measured data in the computer by serial port, and the platform that utilizes computer monitor is presented at the oscillogram of measured data on the computer screen, is convenient to get information about measured data and further analyzing and processing.
Main control chip of the present utility model has single-chip microcomputer P87LPC767 and single-chip microcomputer SPCE061A.The former is mainly used in the modular design of signal Processing, and the latter then is the realization that is used for speech processing module.
