Specific embodiment is as follows:
As shown in Figure 1, the measuring beam that power valve T1 sends carries out after the uniform treatment through frosted glass 1, shines on the receiving tube T2 of photoelectric tube through low pass filters 2 again; It is that wavelength is the photosignal of 700nm that power valve T1 launches, and optical signal beam is through becoming even behind the frosted glass under the effect of frosted glass; Cutoff wavelength is that the low pass of 850nm is considered the interference that wave plate can effectively weaken various clutters, and the interference free performance that light path is detected is improved.
Shown in accompanying drawing 2 and accompanying drawing 3, the light path of native system detects and realizes that principle is to utilize the parallel nature of light transmission, the method that can cast a shadow when the light transmission route has object.When utilizing emitted light shone directly into the reception photoelectric detective circuit, the equatorial projection on photoelectric receiving tube T2 was that a length is d1, highly is the window of h; When silk (monofilament) is arranged in the scope of Photoelectric Detection, silk can be sheltered from the irradiation light of a part, and producing a width at the detection window of T2 is silk diameter d 2, highly is the cast shadow of h, be V1 at the voltage that T2 produces this moment, is set as normal wire comparative voltage.She is Dinged Hold-those joint comparative voltage V2, and being equivalent to equatorial projection on T2, to be set to a length be d2, highly is the window of h.During the silk motion, because the situation that has a lot of fiber fines silks to fall apart outward on the silk has caused output voltage V to change, variable quantity is
, and
Proportional with the variable quantity of the projected area of silk; Because adopt negative feedback automatically to adjust emission light intensity technology in circuit, the light intensity that power valve is launched and the projected area of silk are also proportional; At this moment, can realize detecting the situation that silk is walked about by the change detected amount.During by detection zone, the area that irradiation light is blocked becomes suddenly large or diminishes Dang You Hold-those joint, and the projected area that the photoelectricity receiving circuit receives irradiation light diminishes suddenly or becomes greatly, and when projected area during greater than d2 * h, its result is output voltage
, can Pan Ding and Wei the Hold-those joint, thereby realize the purpose of Jian Ce Hold-those joint.
In the process of measuring, tested silk will double swerve, but as long as silk rock the detection window that does not exceed T2, the projected area of silk on the T2 detection window is constant so.This shows, in the limited result who does not affect measurement that rocks of the excessive middle silk of measuring.
The principle of work of monofilament mass detector is that the variable signal that produces when utilizing monofilament to walk about in the sensing range of detecting device photoelectric tube judges that the motion, Hold-those of silk saves and the breakpoint situation.
In monofilament is still in the sensing range of sensor or in the sensing range of sensor without any thing the time, output voltage V＜V1, single-chip microcomputer judges that by inner high speed analog to digital converter real-time sampling the monofilament wire situation of silk is without the wire RST.
When moving in the sensing range of monofilament at detecting device, because monofilament is one situation loose outside a lot of filaments is arranged among a small circle, so will change in very among a small circle at one the shielded area of light when monofilament moves in the detecting device sensing range, and these change the variation that can produce corresponding output signal.Sort signal be a kind of by a small margin, random alternating signal, when its by signal transformation circuit, DC-isolation, signal shaping, obtained the wire signal by the sampling of single-chip microcomputer internal mode number converter after a series of mimic channels.If Dai You Hold-those joint (Hold-those joint is very large with respect to those filaments of dispersing on certain section monofilament), when it passes through the detection zone of detecting device, can produce a much larger jump signal of the normal wire signal amplitude of ratio.This jump signal is by after signal shaping, the signals reverse circuit, can be respectively by the sampling of the analog to digital converter of single-chip microcomputer inside, then will adopt amplitude numerical value compare and draw last result and carry out Hold-those joint counting with establishing fixed Hold-those joint range value (Hold-those joint range value can be set according to actual needs).
Fracture of wire occurs or reel off raw silk from cocoons when finishing when monofilament moves in the detecting device sensing range, the output signal of circuit just becomes zero.At this moment the internal mode number converter of single-chip microcomputer sampling that output signal is continued for some time, if the signal that detects during this period of time all is zero-signal, single-chip microcomputer then is judged as break point signal.
As shown in Figure 4, when silk moves in photoelectric detector surveyed area scope, photoelectricity receiving circuit in the Photoelectric Detection module can export one by a small margin, random, the signal that alternation changes, the size of this signal power can be regulated by the resistance that single-chip microcomputer changes digital regulation resistance, and then the reception signal amplitude of receiving circuit in the control photoelectric detective circuit.
The signal of Photoelectric Detection module output, carrying out signal by signal shaping 1 module amplifies, and be divided into three the tunnel: the DC-isolation module of leading up to filters flip-flop, is amplified to certain multiple so that single-chip microcomputer internal mode number converter carries out data acquisition (being wire signal AD monitoring 1) through signal shaping 2 modular circuits again; Another road is the automatic feedback circuit module of entering signal balance then, remake the radiating circuit for photoelectric detective circuit, the power that automatic control transmits is (namely when signal is changed by low (height) to high (low), the height variation of signal is that signal voltage and rear a signal voltage constantly of previous moment compares, and the scope of the output voltage values of signal is 0 to 2.5V.Signal is controlled the emission power of photoemission cell to reach the state of a mobile equilibrium by backfeed loop); The collection (being that frame diagram Zhong De Hold-those joint signal AD monitors 2 He Hold-those joint signal AD monitoring 3) that forward signal and negative-going signal are then carried out by offering respectively single-chip microcomputer internal mode number converter after signal shaping 3 modules and the shaping of signals reverse modular circuit in last road.
Single-chip microcomputer so just can be controlled the detection sensitivity of detecting device by the gain of receiving circuit in the control figure potentiometer control photoelectric detective circuit.The prerequisite of Shi other Hold-those joint signal is that wire signal AD monitors the useful signal that monitors wire in 1 module in one-chip computer module, and the monitoring result that Gen Ju Hold-those joint signal AD monitors 2 He Hold-those joint signal AD monitoring 3 under the effective prerequisite of wire signal is again identified Shi Fou You Hold-those joint and passed through.
Peripheral data acquisition unit can by the Modbus RTU communications protocol password of standard, read the breakpoint in the single-chip microcomputer, first disconnected length, length Ji the value of Hold-those joint register.Various systematic parameters are set such as the sensitivity of Photoelectric Detection, the setting at the amplitude of the baud rate ， Hold-those of single chip communication joint, length, interval.
Can obtain the function that hardware circuit possesses from accompanying drawing 4 has:
(1), detects the wire signal;
(2), detecting forward and Fu might be that the jump signal of forward also might be the jump signal of negative sense or both have Xiang Hold-those joint signal: Hold-those joint signal.Signal can produce a signal that becomes large or diminish and have two-way to detect respectively forward signal sudden change and negative-going signal sudden change in the hardware circuit when You Hold-those saves by detection zone, and Que Bao Hold-those saves the accuracy rate of input; The present embodiment only detects the jump signal of forward.
(3), negative feedback is adjusted signal-balanced automatically: cocoon solution silk out generally is that middle one section thick both sides are thinner, so when the front portion of silk wire thick (carefully) fades to carefully (slightly), the photoelectric tube radiating circuit is processed and acted on to the signal of output by negative feedback automatic adjustable balance circuit module, reduce (raisings) thus the emissive porwer of photoelectric tube makes the signal of final Photoelectric Detection modular circuit output again reach a new mobile equilibrium and is unlikely to is thought by system by mistake (Pan Duan is to work as to detect in the regular hour scope that (the time range default value of native system is 16*0.03ms Wei Hold-those joint signal to Shi Hold-those joint signal, this value can be set at host computer according to reality) jump signal that produces all Dings De Hold-those economize on electricity flat (value of this system default is inner 8 analog to digital converters of 115*2.5/256 v--single-chip microcomputer, and reference voltage is 2.5V) greater than She);
(4), Photoelectric Detection sensitivity is adjustable: regulate the power that receives signal by the Single-chip Controlling digital regulation resistance, thereby realize the control of detector sensitivity.
What software section adopted in the system of this monofilament mass detector is the Modbus-RTU communications protocol of standard, and communication interface is 485 general half duplex mode of communication.The workflow of system software is shown in accompanying drawing 5 and accompanying drawing 6.
