Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of printers, and particularly relates to a printer paper feeding motor control method and device based on RT-Thread and a storage medium. BACKGROUND

[0002] In the current printer paper feeding motor control work scenario based on the RT-Thread system, there are many problems to be solved. These problems not only hinder the research and development link, but also seriously affect the overall efficiency of the printing work. In terms of the paper feeding motor control interface, the current situation is that different types of printers must match different paper feeding motor control interfaces corresponding thereto. This means that every time a new printer model is introduced, the research and development personnel need to spend a lot of effort to develop a specific control interface that adapts to the model, greatly increasing the research and development cost and workload. More importantly, the existing same control interface function is extremely simple, and can only control a certain attribute of the paper feeding motor. For example, the paper feeding motor speed control interface is limited to the control of the speed attribute, and other important attributes of the paper feeding motor, such as the moving distance, the motor steering, the motor acceleration, etc., cannot be controlled through the interface. If these different attributes need to be controlled, the research and development personnel have to develop again and redesign the relevant control logic and program code. This situation undoubtedly seriously affects the work efficiency of the research and development personnel, and forces them to be involved in the tedious and repetitive interface development and attribute adaptation work instead of concentrating on optimizing the control algorithm and improving the system performance.

[0003] From the perspective of reusability, the existing printer paper feeding motor motion control method under the RT-Thread system has obvious defects. The control method can only be used for a single machine, and lacks universality and portability. That is, the paper feeding motor control scheme developed for a specific printer cannot be directly applied to other printers, even if these printers have many similarities in the basic principles and functional requirements of the paper feeding motor. Moreover, the paper feeding motor device is not effectively encapsulated by the RT-Thread system bottom layer, which further aggravates the lack of reusability. Every time a new printer application scenario is faced, it seems to start from scratch to build the entire paper feeding motor control system, resulting in a large amount of human and material resources wasted in repeated development work, and also bringing many inconveniences to the maintenance and management of the device.

[0004] In the actual control operation of the paper feed motor, only a single attribute of the motor can be set and adjusted at present, which cannot meet the complex and changeable printing requirements. For example, in some high-precision printing tasks, it may be necessary to accurately control multiple attributes of the paper feed motor, such as speed, moving distance and motor direction, to ensure that the paper moves accurately according to the predetermined trajectory and speed, thereby achieving high-quality printing. However, the existing control method cannot do this, resulting in problems such as inaccurate paper positioning and misaligned printing content during printing, which seriously affects the printing quality. Moreover, after adjusting the attributes of the paper feed motor, the current state of the paper feed motor cannot be obtained in real time, which makes the operator unable to understand whether the motor is working as expected and whether there are abnormal conditions. Once a problem occurs, it often takes a lot of time to troubleshoot the fault, further reducing the efficiency of the printing work and making the entire printing process slow and unstable.

[0005] Therefore, there is an urgent need for a simple and highly reusable printer paper feed motor control method. SUMMARY

[0029] S5, according to step S2, encapsulating the control system and the device driver of the printer to form a system layer.

[0030] Preferably, in the step S2, the paper feed motor and the device layer of the RT-Thread system are encapsulated, the bottom paper feed motor driving layer, the middle protocol conversion layer and the upper application interface layer are designed separately, and the layers communicate through explicit interfaces.

[0031] Preferably, in the step S1, the multi-attribute component includes components for controlling the speed, direction, displacement, acceleration and torque of the paper feed motor, specifically including a driving module, an attribute configuration module, a state detection module, a control algorithm module and a communication interface module.

[0032] The driving module includes a bottom driver for the paper feed motor hardware, is responsible for direct interaction with the control chip, sensor interface and motor driving interface at the hardware level, and realizes initialization, configuration and data read-write operation of the hardware device.

[0033] The attribute configuration module is responsible for configuring the multi-attribute of the paper feed motor, allowing users or external application programs to set the attribute values of the speed, direction, displacement, acceleration and torque of the paper feed motor, and predefining and limiting according to the model, specification of the motor and the overall requirements of the printer, to ensure the normal operation of the motor.

[0034] The state detection module is responsible for real-time monitoring of the running state of the paper feed motor, analyzing and evaluating the current state of the motor, and then feeding back the state information to the user or the control system, so as to understand the working condition of the motor in time and make corresponding adjustment.

[0035] The control algorithm module includes algorithms for precise control of the multi-attribute of the paper feed motor, which are optimized and adjusted according to the characteristics of the paper feed motor, the requirements of the printing task and the actual application scenario, to improve the precision and efficiency of the control.

[0036] The communication interface module is responsible for establishing communication connection with external application programs or other system components, and through the communication protocol, the external application programs send control instructions to the component, and at the same time the component feeds back the state information of the motor to the external application programs.

[0037] Preferably, in the step S3, the multi-attribute component encapsulating the motor control parameters into the application layer includes an interface layer, a parameter encapsulation module and a logic processing layer.

[0038] The interface layer realizes communication between the multi-attribute component and the external application, sends control instructions and obtains the state information of the motor.

[0039] The parameter encapsulation module receives various control parameter values from external application programs for effective processing and transmission within the component.

[0040] The logic processing layer performs logical judgment and processing according to the motor control parameters packaged by the parameter packaging module and the information inside the component.

[0041] Preferably, in the step S4, an access mechanism of the paper feed motor is arranged inside the component, including a state feedback module, which feeds back real-time state information of the paper feed motor to an external application program.

[0042] Preferably, in the step S2, the name of the paper feed motor is directly embedded into the device layer of the RT-Thread system, and at the same time, the model information of the paper feed motor is input, and the parameter threshold of the paper feed motor is set, such as the model, rated power, rated speed, maximum torque, moment of inertia and other physical parameters of the motor, and the production batch and the last maintenance date of the motor and other maintenance related information. These information can be stored in a specific data structure of the device layer, which is convenient for query and reference in the subsequent control and maintenance process.

[0043] Preferably, in the step S2, the interface between the device layer and the paper feed motor is optimized to improve the efficiency and reliability of data transmission. High-speed data bus such as SPI, I2C, etc. is used for data transmission, and data caching mechanism is set to reduce the risk of delay and loss in data transmission process. At the same time, data check and error correction function is set at the interface, such as CRC, cyclic redundancy check algorithm, which can automatically correct errors or request retransmission when data errors are found.

[0044] Preferably, in the step S2, intelligent control logic is added to the control system to automatically adjust the attributes of the paper feed motor according to the current print task type of the printer, such as document, image, poster, paper type, A4, A3, photo paper, etc., and the print quality requirements set by the user, such as resolution, color mode, etc. For example, when printing high-quality images, the control system can automatically reduce the speed of the paper feed motor and increase the torque to ensure the accuracy and stability of the paper movement; when printing posters and other large-format papers, the displacement step and acceleration of the motor are adjusted reasonably according to the size of the paper and the characteristics of the paper feed mechanism of the printer to avoid paper jamming or inaccurate positioning. By continuously monitoring and analyzing the real-time running data of the paper feed motor (such as current, voltage, speed, etc.), a fault prediction model is established. For example, when the current fluctuation of the motor exceeds the normal range for a period of time, or the speed is unstable and accompanied by abnormal vibration, the control system can predict the possible fault types of the motor (such as motor winding short circuit, bearing wear, etc.) in advance, and timely send warning information to the external application program or the operation interface of the printer to prompt the user to check or maintain to avoid further deterioration of the fault and affect the printing work.

[0045] Preferably, in the step S3, the motor control parameters are grouped according to different attribute categories, and a hierarchical encapsulation method is established. For example, the speed-related parameters are grouped into one group, the direction-related parameters are grouped into another group, and so on. When encapsulating, each group of parameters is first encapsulated into a sub-structure body, and then these sub-structure bodies are combined into a total control parameter structure body. Such an encapsulation method makes the parameter structure more clear, facilitates management and transmission, and is also conducive to flexible selection and adjustment of part of the parameter groups according to the needs in different application scenarios.

[0046] Preferably, in the step S3, after the encapsulated control parameters are transmitted to the multi-attribute component of the application layer, strict parameter verification is performed inside the component. According to the actual performance of the motor, the current working state of the printer, and the pre-set parameter range, the incoming parameters are verified one by one. If it is found that the parameters are illegal or do not meet the current working conditions, error information is returned to the external application program in time, and the correct parameter setting range or adjustment direction is prompted. At the same time, according to the verified parameters, the component internally performs adaptation processing, and converts the parameters into a form that can be understood and executed by the paper feed motor drive program and control system. For example, the user-set speed value is converted into a duty cycle of the corresponding pulse width modulation signal, etc., so as to accurately control the speed of the motor.
