The temperature control method of the existing laying equipment is mainly based on an empirical method and a thermal radiation mathematical modeling, wherein the empirical method is to sum up the relation between the heating power of an infrared heating element and various parameters during laying through a large amount of test data, the method lacks theoretical basis, the experimental data is limited, and the application scene is limited; the mathematical modeling of the heat radiation is to establish a heat radiation equation and express the relation between the power of the infrared heating element and various parameters during laying by determining equation coefficients, and the method does not consider the influence of the response time of the wavelength of the infrared heating element during high-speed laying, namely the radiation of the infrared heating element can only heat the surface of the prepreg and cannot penetrate the inside of a prepreg narrow band. In general, the heating power determined according to the heat radiation equation may not meet the heating requirement of high-speed wire laying by passing a current from the filament of the infrared heating element until heat radiation is normally generated for a reaction time exceeding 1 minute. In addition, in the laying process, the infrared heating element is required to be continuously subjected to power adjustment in real time according to the ideal temperature of each part of the laying layer, so that the laying difficulty is increased.

As one embodiment, the step S1 of obtaining current temperature data and current operation data of the wire spreader includes:
s11, judging whether the laying speed of the wire laying machine is zero.
S12, if the judgment result is negative, acquiring the current operation data and the current temperature data; the current operation data comprise the laying speed of the wire laying machine, and the current temperature data comprise the heating temperature, the environment temperature and the actual laying temperature.
And S13, if the judgment result is yes, stopping the operation of the infrared heating element of the wire laying machine.
In this embodiment, whether the laying speed of the wire laying machine is zero is determined as a condition for acquiring the current temperature data and the current operation data of the wire laying machine, when the laying speed of the wire laying machine is zero, the wire laying machine may be in a state with low infrared heating requirements such as shutdown or standby, and if continuous infrared heating is maintained, the laying effect of a part of the laying area may be affected; when the laying speed of the wire laying machine is not zero, which means that the wire laying machine is working, the current operation data and the current temperature data need to be acquired for subsequent processing. By setting the judgment premise of acquiring data, the energy can be saved, the machine abrasion can be reduced, and the automaticity and the working efficiency of infrared heating control can be improved.
As one embodiment, the step S2 of obtaining the set temperature data of the infrared heating according to the current temperature data and the current operation data includes:
s21, obtaining the set power of an infrared heating element of the wire laying machine according to the following relation;
P setting up ＝K·v·(T Setting up -T Actual practice is that of )，
Wherein P is Setting up Representing the set power of an infrared heating element of the wire laying machine, K representing a proportionality coefficient, v representing a laying speed and T Setting up Indicating the set temperature of the layer, T Actual practice is that of Indicating the actual temperature of the layup.
The above formula is further described below in connection with a specific application scenario.
In some embodiments, the composite material laid by the wire laying machine is a prepreg narrow band, fig. 5 shows the relationship between an infrared heating element and the laying layer, the infrared heating element is an infrared lamp, the infrared lamp is composed of a tungsten filament, a quartz tube and a gold-plated reflecting film with a heat insulation layer, the filament is wound into a spiral cylinder shape, an electric joint is fixed by using a ceramic material, and the rated working state heat radiation wavelength of the infrared lamp is short wave, thus the surface of the filament is regarded as a diffusion surface, the gold-plated reflecting film is coated on the upper half part of the quartz tube, the whole reflecting film layer can be regarded as mirror reflection, the heat radiation performance of the surface of the filament is similar to the blackbody surface defined in Stefan (Stefan) -Boltzman law, and the relationship between the heat source and the prepreg laying environment is as follows when the infrared lamp is laid in a heat balance state:
Wherein, P is infrared lamp electric power, S lamp is filament effective radiation area, E lamp is filament radiation intensity, epsilon is filament emissivity, sigma is Boltzmann constant, T lamp is filament temperature, zeta is filament spiral arrangement density coefficient, R lamp is filament radius, L lamp is filament length.
The heat transfer mode of the infrared heating element for heating the prepreg surface is mainly heat radiation, and although heat conduction and heat convection exist simultaneously, the heat energy transferred by the infrared heating element and the prepreg surface is completely negligible for engineering application of the prepreg surface heating, because the infrared lamp is mounted on the fixed support, the position of the heating lamp relative to the heated prepreg surface is kept unchanged when the infrared lamp is laid, and the heat radiation only occurs in a limited area. Therefore, the prepreg absorbs heat radiation energy Q in two parts, one part is energy Q of direct radiation of filaments to the surface of the prepreg Straight line Another part is energy Q indirectly reflected to the surface of the prepreg through the reflective film coating Interval (C) The prepreg surface is regarded as an ash body, the absorptivity alpha of the ash body is constant, and the effective radiation energy absorbed by the prepreg surface in unit time is as follows:
Q＝α(Q straight line +Q Interval (C) )＝α(E Lamp with light-emitting device S Lamp with light-emitting device X 1.3 +ρE Lamp with light-emitting device S Lamp with light-emitting device X 1.2 X 2.3 )＝α(X 1.3 +ρX 1.2 X 2.3 )P
Wherein ρ is the reflectivity of the reflective film coating, X 1.3 Is the angular coefficient of the surface of the filament and the surface of the prepreg, namely the energy ratio of the surface of the filament directly radiated onto the surface of the prepreg, X 1.2 For the angular coefficient of the radiation from the filament surface to the surface of the reflective film, i.e. the energy duty ratio of the radiation from the filament surface to the surface of the reflective film coating, X 2.3 The angular coefficient of the reflection film coating reflected to the surface of the prepreg, namely the energy ratio of the reflection film coating reflected to the surface of the prepreg.
When the prepreg is automatically laid, the infrared lamp moves at a fixed position on the surface of the prepreg at a given laying speed, the radiation energy of the infrared lamp is received by the surface of the prepreg, and the relationship between the temperature change of the surface of the prepreg and the heat radiation energy of the received infrared lamp is as follows:
wherein C is the specific heat capacity of the prepreg, M is the mass of the prepreg on the effective radiation surface, deltaT is the temperature rise value of the prepreg surface, L is the length of the effective radiation surface along the direction of the laying track, and V is the laying speed of the center point of the cutter of the wire laying machine along the direction of the laying track. At the optimal temperature meeting the technological requirement of the prepreg laying surface, the relationship between the electric power of the infrared lamp and the laying speed is as follows:
as the filament surface is regarded as a diffusion surface, the normal working state can be regarded as equal-intensity radiation, the angle coefficient is only related to the sizes and shapes of the filament surface and the prepreg surface and the installation position of the infrared lamp bracket, the installation position of the infrared lamp bracket is compatible with the overall layout of the wire laying head, and the optimal installation position selection can be carried out through simulation and test so as to obtain the radiation intensity as high as possible and better temperature uniformity. Because the relative position of the heating infrared lamp on the wire laying head and the laying surface of the prepreg is constant, the effective heating area S of the prepreg laying is unchanged, and the angle coefficient X is the same 1.3 ，X 1.2 ，X 2.3 Is constant, so the control mathematical relationship of the heating infrared lamp is:
P＝KV△T
wherein,in the K value expression, all values are constant, and K is constant.
According to the formula: as is known from p=kv Δt, the power setting of the infrared lamp is in a proportional relationship with the laying speed and the temperature difference required for heating the prepreg, K is a constant, which is related to the specific heat capacity, mass, absorptivity, effective radiation surface area of the heating lamp, mounting position of the lamp holder, etc. of the prepreg. When the environment temperature changes, the surface temperature of the prepreg changes, or when the prepregs with different brands are replaced, the viscosity of the surface of the prepreg changes, and the K value needs to be corrected.
In this embodiment, the heating temperature, the ambient temperature and the actual temperature of the laying layer of the infrared heating unit are collected by the collecting unit of the infrared heating control system, and the data are transmitted to the control processing module CMD through the first analog input module A2 and the second analog input module A3, and meanwhile, the control processing module can also directly read the laying speed of the wire laying machine, so that the control processing module CMD can process after receiving the data. The purpose of detecting the temperature of the infrared lamp is to ensure that the infrared lamp works in a short wave intermediate band under rated conditions, otherwise, the problems of short service life of the filament and slow cold start response are caused. The detection of the ambient temperature is to judge whether the temperature difference between the temperature and the surface temperature of the layer exceeds 2 ℃, and the K value needs to be corrected if the temperature difference exceeds the temperature difference. The detection of the surface temperature of the laying layer is the control of electric power output when the prepreg reaches the temperature required by the laying process.
Specifically, taking an actual operation process as an example, the control processing module CMD reads the ambient temperature at intervals of 0.5S or continuously, when the wire laying machine lays, the numerical control system directly reads the synthesis speed of the center of the cutter, that is, the real-time laying speed of the wire laying machine, then reads the required power instruction set value from the set parameter set DB block (the DB module is a data block in the PLC and is used for data transmission inside the PLC), converts the value into the range input corresponding to the analog output module A1, and the analog output module A1 outputs the driving current of 4-20mA in terms of the range, and drives the adjusting unit to adjust (such as the change of the conduction angle of the power regulator PR), thereby controlling the current introduced into the infrared heating element and changing the magnitude of the infrared radiation power. The adjusting unit is connected with a measuring module D (such as a current transformer), so that the current fed by the infrared heating element can be directly obtained and directly fed back to the control processing module CMD.
In some embodiments, the range of the environmental temperature data is 0-35 ℃, the range of the environmental temperature step change is 1 ℃, the range of the laying speed is 0.01-1.2 times of the maximum laying speed of the wire laying machine, and the number of segments is set according to the requirement of the composite material laying process parameters; in addition, the power of the infrared heating element can be equally divided from 0 to rated power by 256, and the output current of the infrared heating element is 4-20mA corresponding to the analog quantity of the analog quantity output module A1.
In some embodiments, in particular, the relationship between the deposition rate and the deposition temperature (which can be converted to the set power by the aforementioned formula) can also be found by a data fitting algorithm, so that the control processing module CMD generates real-time control instructions.
As one embodiment, the set temperature data includes a set power. Specifically, the set temperature data is selected as comparison data of the output temperature data, that is, the data attribute of the set temperature data is consistent with the data attribute of the output temperature data, and the data attributes of the set temperature data and the output temperature data may include power, current, voltage, and the like. In the present embodiment, the set power is used as the set temperature data, and the above formula can be usedThe obtained output temperature data (output power comparison) is conveniently compared with feedback in a subsequent step without conversion for further adjustment.
According to the analysis, the setting power required by adjustment can be calculated according to the laying speed of the wire laying machine and the actual temperature of the laying layer, which are acquired by the acquisition unit in real time, and the power output to the infrared heating element is controlled by the real-time control instruction of the control processing module CMD, so that the better laying state is obtained by controlling the laying temperature in real time, and the laying effect of the wire laying machine is improved.
As one embodiment, the step S3 of obtaining the real-time control command of infrared heating according to the output temperature data and the set temperature data includes:
s31, calculating deviation of the output temperature data and the set temperature data;
s32, taking the deviation as input of a PID control algorithm, and obtaining a control quantity corresponding to the deviation according to the following relation:
wherein u (t) is a control amount, e (t) is a deviation, K p To control the proportional gain of the law, T i To control the integration time constant of the law, T d A differential time constant that is a control law;
and S33, generating the real-time control instruction according to the control quantity corresponding to the deviation.
As can be seen from the foregoing embodiments, a closed loop is formed between the control unit and the adjustment unit in the infrared heating control system, and the adjustment unit may feed back the current, voltage or power, etc. output to the infrared heating element to the control unit, so that the control unit generates real-time control instructions according to the PID control algorithm. The real-time control instructions may include, among other things, current, voltage, or power values output to the infrared heating unit.
The output control amount based on the PID control algorithm is a conventional technical means in the automation field, and the principle and application of the control algorithm are not described in detail here.
As an embodiment, after the step 4 of outputting the real-time control instruction to the adjusting unit to enable the adjusting unit to adjust the current parameters of the infrared heating element of the wire laying machine according to the real-time control instruction, the method further includes:
s5, returning to execute the step of acquiring the current temperature data and the current operation data.
In this embodiment, after the infrared heating element receives the adjustment parameters of the real-time control command, the temperature of the infrared heating element may not be constant and may fluctuate, and there is a need for adjusting the temperature, so that the step of acquiring the current temperature data and the current operation data is returned to form a cycle in time and send out the dynamic continuous real-time control command, thereby obtaining a better heating effect.
