Embodiment 1:
As shown in Figure 1, a kind of heating control system of optical fiber hot soarfing device, is provided with firing equipment in optical fiber hot soarfing device, and this firing equipment is generally heating plate.The heating control system of optical fiber hot soarfing device comprises main control unit 1, adds thermal control units 2, heating cover detecting unit 3 and state indication unit 4, wherein, main control unit 1 respectively with add thermal control units 2, heating cover detecting unit 3 and state indication unit 4 and be connected.
Main control unit 1 comprises pid control module 11.Add thermal control units 2 and comprise PWM output module 22, temperature detecting module 21 and overheating protection module 23, PWM output module 22, temperature detecting module 21 and overheating protection module 23 are connected with firing equipment respectively; Wherein, overheating protection module 23 is for carrying out overheating protection to firing equipment.State indication unit 4 comprises mode of operation indicating module and heating-up temperature indicating module.
In main control unit 1, store default heating-up temperature value; Temperature detecting module 21 is for detecting in real time the temperature of firing equipment, and the current temperature value detecting is sent to main control unit 1; Pid control module 11, according to heating-up temperature value and current temperature value, adopts the numeral output of PID control method control PWM output module 22, then by numeral output, the heating process of firing equipment is controlled.
The predetermined manner of heating-up temperature value can adopt the mode that gear is selected or numeral is inputted, the mode that the present embodiment adopts gear to select, 60 ℃, 80 ℃, 100 ℃ and 120 ℃ four conventional temperature gears are provided, but be not limited to this, also can adopt by the directly mode of the temperature required value of input of keyboard.
The heating control system of optical fiber hot soarfing device can arrange multiple-working mode as required, and the present invention is not restricted this.In the present embodiment, comprise two kinds of mode of operations: normal operating mode and power-saving working mode.Wherein, power-saving working mode is holding state, and optical fiber is put into optical fiber hot soarfing device, and optical fiber hot soarfing device is not worked; When in normal operating mode, optical fiber is put into optical fiber hot soarfing device, heating control system starts to add heat control, controls optical fiber hot soarfing device and completes fiber stripping work.
In the present embodiment, mode of operation indicating module comprises two LED light, is respectively used to indicate normal operating mode and power-saving working mode.
Whether in the present embodiment, heating control system is provided with heating cover detecting unit 3, close, and send a detection signal to main control unit 1 according to testing result for detection of the heating cover of optical fiber hot soarfing device.When in normal operating mode, main control unit 1 judges this testing result, if heating cover is closed, main control unit 1 is controlled firing equipment and heated by adding thermal control units 2.Wherein, heating cover detecting unit 3 can be Hall element or optocoupler sensor.
Heating-up temperature indicating module is display screen or some LED light.
As shown in Figure 2, the workflow of the heating control system of optical fiber hot soarfing device is as follows:
(1) judge mode of operation, if continue in normal operating mode; (2) set heating-up temperature value; (3) judge whether heating cover closes, continue if heating cover has been closed; (4) pid control module 11 is controlled firing equipment and is heated.
As shown in Figure 3, a kind of method for heating and controlling of optical fiber hot soarfing device, comprises the steps:
Initial step: heating-up temperature value is set as required;
Heating steps: according to the default sampling period, the current temperature value of Real-time Collection firing equipment; According to heating-up temperature value and current temperature value, adopt PID control method control firing equipment to heat;
As shown in Figure 4, below in conjunction with formula, PID control method is specifically described:
Step S1, arranges initial pid parameter, pid parameter comprise scale-up factor, integral time coefficient and derivative time coefficient.
System at k-1 moment PID is exported as the formula (1):
Wherein, T is the sampling period, and e is system input, and u is system output, K
pfor scale-up factor, T
ifor coefficient integral time, T
dfor coefficient derivative time.
Because the codomain of the numeral output of PWM is 0～0xF000, in the present embodiment, sampling period T get 1024, three pid parameters initially to get following value comparatively suitable: K
p=8, T
d=8, T
i=1024, adopt numeral output that above-mentioned initial value can make PWM 0 to+0x7FFF or-change between 0x8000 to 0.
The system output in k moment and the system output in k-1 moment are subtracted each other, obtain an output increment as the formula (2):
Wherein, Δ u
kfor output increment.
Step S2, the difference by the system input of PID corresponding to heating-up temperature value and current temperature value; Adjust in real time pid parameter according to the variation of the system input of PID.
Step S2 further comprises:
Step S21 in the time that the system input of PID is larger, tunes up scale-up factor as far as possible, and firing rate is accelerated.In the present embodiment, in the time that the difference of heating-up temperature value and current temperature value is greater than 110 ℃, think that the system input of PID is larger; Now tune up scale-up factor, be to make Proportional coefficient K as far as possible
pthe span of 8(scale-up factor of as far as possible leveling off to is 0～8).
In the time that the difference of heating-up temperature value and current temperature value is very large, the temperature of firing equipment is also very low, is far from the heating-up temperature value that reaches default, now needs to accelerate firing rate as far as possible, makes the heating-up temperature value that reaches as early as possible default.Because the difference of heating-up temperature value and current temperature value is inputted corresponding to the system of PID, when the difference of heating-up temperature value and current temperature value is very large, the system input of PID is also larger.Can be found out Proportional coefficient K by formula (2)
pvalue larger, heat faster.Therefore, in the time that the system input of PID is larger, tune up scale-up factor as far as possible, firing rate is accelerated.
Step S22, according to the error of two time period systems inputs, to derivative time coefficient regulate, make PID system keep stable.
Heating PID system fast will be unstable, regulates coefficient T derivative time in this step
dbe in order to reduce overshoot, thereby make PID system keep stable.
Below the definition of " overshoot " is explained: the legal value scope of temperature control of systemic presupposition ± 2 ℃, in the time that system input difference (difference of the heating-up temperature value of also setting and the current temperature value collecting) does not change within the scope of systemic presupposition, be called overshoot.When after system stability, in preset range, repeatedly change and regulate temperature, the difference of this forward and reverse extreme value repeatedly changing is called overshoot.This amount is larger, and the improved space of pid algorithm is larger, and also this PID temperature control effect is poorer.
Suppose the explanation as an example of this moment of k-1 example, by
can find out that this part result is by the k-2 moment (moment in past), in the k-1 moment (present moment), the k moment (future time) determines, regulates this of coefficient T derivative time
dcan adjust the error of two time periods (k is to k-1 moment and k-1 to the k-2 moment) system input, thus effective systems stabilisation.Specifically: if controlled device (firing equipment) temperature variation affected by environment is large, e so
k-e
k-1with e
k-e
k-2difference just large, in order to reduce overshoot, if e
k-e
k-1with e
k-e
k-2difference large, T
djust reduce; If e
k-e
k-1with e
k-e
k-2difference little, stable slowly, T
djust increase.Derivative time coefficient T
dspan be 0～8.The difference here refers to greatly 2 ℃ of difference >, little difference≤2 ℃ that refer to of difference.
Step S23, according to system, input regulates coefficient integral time, and the temperature difference is increased, thus the output of increase system.
After PID system stability, will consider prolongation in time, system works environment also can constantly change, and in order to solve the problem of this part, needs to regulate coefficient T integral time
i, the temperature difference is increased.By
can find out, the temperature difference raises, and also and then this moment increases together in the system output of PID.
Because pid algorithm is increment type, so, the difference that the integrated value in integration amount k moment and k-1 moment integrated value relatively draw is exactly the value in k moment
so the size of PID coefficient integral time of increment type is only relevant with current temperature approach.So, in the time that system inertia is large, e so
kmust increase,
in like manner also increase, output nature increases; Output increases, e
kmust reduce, the inevitable balance of system is got off so.At this moment need T
iregulate T
ireduce,
just increase, system stability is fast; Otherwise, if T
iincrease,
just reduce, system stability is slow.Integral time coefficient T
ispan be 0～8.
Adopt above-mentioned method for heating and controlling can make working temperature rise to fast and stably default heating-up temperature value, as shown in Figure 5.For ease of explanation, this figure is by the pulse width values (curve of output) of main control unit 1 output module output, former and later two moment temperature gaps (collection value curve) and the reference value 100(setting value straight line that main control unit 1 calculates) entity present in a figure.When temperature gap is larger, pulse width can become greatly thereupon, i.e. the beginning of horizontal ordinate in figure; When temperature gap diminishes gradually, pulse width values also corresponding adjustment diminishes; When temperature gap is less than or equal to predetermined threshold value, pwm value does not also change thereupon; When in the course of work, temperature gap has fluctuation, and pwm value also can change thereupon, in figure, has more micromutation.
Disclosed is above only several specific embodiments of the application, but the not limited thereto the changes that any person skilled in the art can think of of the application all should drop in the application's protection domain.
