[0029] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be described clearly and in detail below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in the field based on the embodiments in the embodiments of the present invention should fall within the scope of protection of the embodiments of the present invention.

[0030] The specific implementation of the embodiment of the present invention is further described below in conjunction with the accompanying drawings of the embodiment of the present invention.

[0031] For ease of understanding, before describing in detail the specific embodiments of the present invention, an exemplary description is first given of the application scenarios of the control method, device, computer storage medium, and electronic device of the present invention.

[0032] Reference Figure 1AThe control method of the embodiment of the present invention is applied to the control device 101 in the color registration system 100. The color registration system 100 also includes a color registration device 102 and a printing displacement detection device 103. The control device 101 is connected to the color registration device 102 and the printing displacement detection device 103 respectively. The color registration system 100 can be used in a printing machine. The control device 101 can be a PLC. The control device 101 can obtain data from the printing displacement detection device 103 and send a signal to the color registration device 102 to control the color registration device 102 to perform a color registration operation. The color registration device 102 can include a motor, a printing device, etc. The color registration device 102 is used to print color registration on a printing material. The printing displacement detection device 103 can be a color mark sensor, which is used to detect the displacement of a color mark on a printing material.

[0033] At present, the color registration control algorithm used in the color registration system is usually the PID control algorithm. However, the PID control algorithm requires the input of three core parameters: proportional gain, integral time and differential gain. In color registration control, these three parameters will be different for different printing materials and there is no reference standard. Instead, they need to be adjusted manually based on the changing law of the color registration effect, resulting in a large manual workload and complex operation.

[0034] In view of this, embodiments of the present invention provide a control method, device, computer storage medium and electronic device to at least partially solve the above problems.

[0035] Figure 2 The flowchart of the control method of the exemplary embodiment of the present invention is shown in the figure. As shown in the figure, this embodiment mainly includes the following steps:

[0036] S202: Determine a displacement prediction value of the color matching device in the current color matching cycle according to a preset displacement prediction algorithm and a displacement prediction value of the color matching device in the previous color matching cycle.

[0037] The color registering device of this embodiment performs the color registering operation according to a preset cycle, and accordingly, the control device also calculates the displacement prediction value of the color registering device according to the preset cycle. In an optional implementation, the displacement prediction value of the color registering device in the initial color registering cycle is the actual value of the initial printing displacement detected by the printing displacement detection device, so that it is convenient to calculate the displacement prediction value of the color registering device in the next color registering cycle according to the actual displacement value of the color registering device in the initial color registering cycle. The preset displacement prediction algorithm is used to calculate the displacement prediction value of the color registering device in the current color registering cycle according to the displacement prediction value of the color registering device in the previous color registering cycle.

[0038] In an optional implementation, the displacement prediction algorithm includes a first displacement prediction algorithm and a second displacement prediction algorithm, and the displacement prediction value of the color set device in the current color set cycle is determined according to a preset displacement prediction algorithm and the displacement prediction value of the color set device in the previous color set cycle, including: if the displacement adjustment amount of the color set device is not output in the previous color set cycle, then the displacement prediction value of the color set device in the current color set cycle is determined according to the first displacement prediction algorithm and the displacement prediction value of the color set device in the previous color set cycle; if the displacement adjustment amount of the color set device is output in the previous color set cycle, then the displacement prediction value of the color set device in the current color set cycle is determined according to the second displacement prediction algorithm and the displacement prediction value of the color set device in the previous color set cycle; the second displacement prediction algorithm is used to add the displacement prediction value of the color set device in the previous color set cycle and the displacement adjustment amount of the color set device in the previous color set cycle to obtain the displacement prediction value of the color set device in the current color set cycle.

[0039] Exemplarily, the preset displacement prediction algorithm may include two different displacement prediction algorithms: a first displacement prediction algorithm and a second displacement prediction algorithm. Before determining the displacement prediction value of the color set device in the current color set cycle based on the displacement prediction value of the color set device in the previous color set cycle, the displacement prediction algorithm used to predict the displacement prediction value of the current color set cycle may be selected based on whether the displacement adjustment amount of the color set device was output in the previous color set cycle. If the displacement adjustment amount of the color set device was not output in the previous color set cycle, the first displacement prediction algorithm is used to predict the displacement prediction value of the current cycle; if the displacement adjustment amount of the color set device was not output in the previous color set cycle, the second displacement prediction algorithm is used to predict the displacement prediction value of the current cycle. The second displacement prediction algorithm obtains the displacement prediction value of the color set device in the current color set cycle by adding the displacement prediction value of the color set device in the previous color set cycle to the displacement adjustment amount of the color set device in the previous color set cycle.

[0040] In this embodiment, the algorithm for determining the displacement prediction value of the current cycle according to whether the displacement adjustment amount of the color matching device was output in the previous color matching cycle can adapt to different situations to predict the displacement prediction value and ensure the accuracy of the displacement prediction value in different situations.

[0041] In an optional implementation, the displacement prediction value of the color set device in the current color set cycle is determined based on the first displacement prediction algorithm and the displacement prediction value of the color set device in the previous color set cycle, including: obtaining the displacement prediction value of the color set device in the previous color set cycle and the current color set cycle number; through the displacement prediction algorithm, according to the displacement prediction value of the color set device in the previous color set cycle and the current color set cycle number, determining the displacement prediction value of the color set device in the current color set cycle, the parameters of the displacement prediction algorithm also include a preset displacement amount and preset parameters.

[0042] Exemplarily, the color registration system of this embodiment is a time-delay system, and the calculation formula of the first displacement prediction algorithm can be:

[0043]

[0044] Among them, y n is the displacement prediction value of the color matching device in the current color matching cycle, y n-1 is the displacement prediction value of the color register device in the previous color register cycle, t is the current color register cycle number, T is a preset parameter, the preset parameter is a fixed value, x is a preset displacement, the preset displacement is a preset fixed value, and can be the displacement offset between each printing color group in the printing device.

[0045] In this embodiment, the control device can automatically obtain the displacement prediction value of the color matching device in the previous color matching cycle and the current color matching cycle number, and input the displacement prediction value of the color matching device in the previous color matching cycle and the current color matching cycle number into the first displacement prediction algorithm. Other parameters in the first displacement prediction algorithm, including the preset displacement amount and preset parameters, are all fixed values. Therefore, the displacement prediction value of the color matching device in the current color matching cycle can be directly calculated. The calculation process is simple and there is no need to manually adjust any parameters.

[0046] In addition, the differential link in the currently used PID control algorithm is mainly used to solve the problem of control lag in the colorimetric system, but the differential link will also greatly amplify the high-frequency noise and bring adverse effects on the colorimetric system. The calculation process of this embodiment does not involve the differential link, so the situation of amplifying the high-frequency noise and bringing adverse effects on the colorimetric system will not occur.

[0047] In an optional implementation, the color system is a time-delay system, and the preset parameter is the time constant in the unit step time domain response function of the color system. In this embodiment, the color system can be a high-order time-delay system, which meets the model characteristics of the first-order time-delay system, and the preset parameter of the displacement prediction algorithm is the time constant in the unit step time domain response function of the first-order time-delay system. The time constant can be calculated by the unit step time domain response function of the first-order time-delay system, wherein the unit step time domain response function of the first-order time-delay system is:

[0048]

[0049] Among them, y is the response value, t is the response time. A signal can be input into the colorimetric system. According to the curve corresponding to the unit step time domain response function generated by the colorimetric system, the three sets of eigenvalues ​​(T, 0.632), (2*T, 0.865), and (3*T, 0.95) can be determined, and the time constant T can be calculated.

[0050] In this embodiment, based on the characteristic that the color matching system is a time-delay system, the preset parameters in the displacement prediction algorithm, that is, the time constant in the unit step time domain response function of the color matching system, can be quickly calculated, so that the displacement prediction algorithm can be used to predict the displacement prediction value of the color matching device in each color matching cycle in the subsequent process.

[0051] S204: If the difference between the actual value of the current printing displacement detected by the printing displacement detection device and the displacement prediction value is greater than a preset threshold, then determining the displacement adjustment amount of the color registration device in the current color registration cycle.

[0052] Exemplarily, the actual value of the current printing displacement on the printed material can be detected by a printing displacement detection device, that is, the color mark displacement on the printed material can be detected by a color mark sensor, and the control device can obtain the actual value of the current printing displacement detected by the printing displacement detection device, and then calculate the difference between the actual value of the current printing displacement detected by the printing displacement detection device and the predicted displacement prediction value of the color register device in the current color register cycle. If this difference is greater than a preset threshold, it is necessary to output the displacement adjustment amount of the color register device in the current color register cycle, and the difference between the actual value of the current printing displacement and the predicted displacement value of the current color register cycle can be used as the displacement adjustment amount. Here, the preset threshold can be set by a person skilled in the art according to the allowable displacement error range of the color register device, and this embodiment does not limit this.

[0053] In an optional implementation, the displacement adjustment amount of the color registration device in the current color registration cycle is determined based on the current actual printing displacement value detected by the printing displacement detection device and the displacement prediction value, including: if the difference between the current actual printing displacement value detected by the printing displacement detection device and the displacement prediction value is greater than a preset threshold, the initial displacement adjustment amount is determined based on the difference between the current actual printing displacement value detected by the printing displacement detection device and the displacement prediction value; the initial displacement adjustment amount is adjusted according to a preset adjustment coefficient to obtain the displacement adjustment amount of the color registration device in the current color registration cycle.

[0054] For example, an adjustment coefficient may be added to the calculated displacement adjustment amount of the color register device in the current color register cycle, that is, the difference between the actual value of the current printing displacement detected by the printing displacement detection device and the displacement prediction value is first calculated and used as the initial displacement adjustment amount; and then the preset adjustment coefficient is multiplied by the initial displacement adjustment amount to obtain the displacement adjustment amount of the color register device in the current color register cycle. Here, the preset adjustment coefficient may be set by those skilled in the art based on actual experience, and this embodiment does not limit this.

[0055] In this embodiment, by adding a preset adjustment coefficient, after calculating the difference between the actual value of the current printing displacement detected by the printing displacement detection device and the predicted value, the initial displacement adjustment amount is obtained, and then the initial displacement adjustment amount is corrected, thereby further improving the accuracy of the output displacement adjustment amount and achieving a better color registration effect.

[0056] In an optional implementation manner, the reference value of the preset adjustment coefficient is 1.

[0057] Specifically, the meaning of the preset adjustment coefficient is the ratio of the displacement adjustment amount given by the difference between the actual value of the current printing displacement and the predicted value of the displacement, and the present embodiment provides a reference value of the preset adjustment coefficient of 1, that is, in different application scenarios, technical personnel in this field can set a suitable preset adjustment coefficient according to the reference value of the preset adjustment coefficient, thereby reducing the difficulty for technical personnel in this field to set the preset adjustment coefficient in multiple application scenarios, and, in this embodiment, for different application scenarios, only one parameter, the preset adjustment coefficient, needs to be adjusted in the entire calculation process, thereby reducing manual workload.

[0058] S208: Send the displacement adjustment amount to the color matching device to control the color matching device to perform the color matching operation of the current color matching cycle.

[0059] Exemplarily, the control device may generate a control signal according to the displacement adjustment amount, and then send the control signal to the color matching device, and control the color matching device to perform the color matching operation of the current color matching cycle based on the control signal.

[0060] Reference Figure 1B , is a schematic diagram of an exemplary control process of a control method of an embodiment of the present invention, wherein the control device 101 in the color registration system 100 may include a state prediction module 1011 and an adjustment algorithm module 1012, wherein the state prediction module 1011 is used to determine the displacement prediction value of the color registration device 102 in the current color registration cycle according to a preset displacement prediction algorithm and the displacement prediction value of the color registration device 102 in the previous color registration cycle, and send the displacement prediction value of the color registration device 102 in the current color registration cycle to the adjustment algorithm module 1012; the adjustment algorithm module 1012 is used to determine the displacement adjustment amount of the color registration device 102 in the current color registration cycle if the difference between the actual value of the current printing displacement detected by the printing displacement detection device 103 and the displacement prediction value is greater than a preset threshold, and send the displacement adjustment amount to the color registration device 102 and the state prediction module 1011 respectively; the printing displacement detection device 103 is used to send the detected actual value of the current printing displacement to the adjustment algorithm module 1012.
