Description

Technical Field

[0001] The present invention relates to the field of quilting processing, and in particular to a bus communication control method of a quilting system and related equipment. Background Art

[0002] The quilting machine is an automated sewing equipment with high speed, high efficiency and high performance. It is a sewing machine in the home textile industry and clothing industry. In the quilting industry, the usual practice is that the upper computer sends the entire pattern to the lower computer, and relies on the lower computer to process and calculate the segmented stitches. This practice has certain performance requirements on the performance of the lower computer and is not conducive to processing super-large patterns (million stitches level).

[0003] Generally speaking, the performance of the upper computer is better than that of the lower computer. The upper computer calculates and divides the stitches of the quilting pattern, thereby forming a command frame to control the lower computer to complete the quilting. This solution transfers the computationally intensive work such as pattern processing from the lower computer to the higher-performance upper computer, which reduces the performance requirements of the lower computer and saves costs. In addition, the upper computer has a larger memory space, which is more conducive to processing very large patterns. After the upper computer in the prior art divides the quilting process, there is still a lack of an effective and reliable method for command frame bus communication interaction with the lower computer.

[0004] Therefore, the prior art still needs to be improved and developed. Summary of the invention

[0044] In the description of the embodiments disclosed in the present invention, if there are terms, the term "including" and similar terms should be understood as open inclusion, that is, "including but not limited to". The term "based on" should be understood as "based at least in part on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment".

[0045] In the quilting industry (including but not limited to quilt processing and pillowcase processing), generally speaking, the performance of the upper computer is better than that of the lower computer. The upper computer calculates and divides the stitches of the quilting pattern, thereby forming a command frame to control the lower computer to complete the quilting. The computationally intensive work such as pattern processing is transferred from the lower computer to the higher-performance upper computer, which reduces the performance requirements of the lower computer and saves costs. In order to make the communication between the upper computer and the lower computer of the quilting system more orderly and reliable, see Figure 1 The first aspect of the present invention provides a bus communication control method for a quilting system, comprising the steps of:

[0046] S100, obtaining the current state of the quilting system; in the present invention, the quilting system is divided into a quilting state and a standby state. Exemplarily, whether the current state of the quilting system is the quilting state or the standby state can be determined based on whether the quilting pattern list in the quilting system has been completely generated; the quilting system of the present invention includes an upper computer and a lower computer, the upper computer is mainly used to divide the quilting process into individual commands, and send them to the lower computer in the form of command frames, such as return to original, move frame, adjust shuttle and other commands, the lower computer completes the corresponding action according to the command frame sent by the upper computer, the quilting bus technology of the present invention is mainly used to process the command data interaction between the upper and lower computers.

[0047] S200. If the quilting system is currently in standby mode, the bus communication between the upper computer and the lower computer is controlled to perform command interaction in an asynchronous form, and the asynchronous form is that the upper computer periodically sends command frames to the lower computer; in the present invention, two threads (synchronous thread and asynchronous thread) are mainly used between the upper and lower computers to realize two different forms of data interaction (synchronous form and asynchronous form), the asynchronous form of data interaction: the upper computer actively sends a command frame to the lower computer at regular intervals, and the lower computer replies with a response frame after receiving it; the synchronous form of data interaction: the upper computer will send a command frame only after receiving an interrupt signal fed back by the lower computer, and the lower computer will reply with a response frame after receiving it.

[0048] In an optional implementation of the first aspect of the present invention, if the quilting system is currently in a standby state, controlling the bus communication between the upper computer and the lower computer to perform command interaction in an asynchronous form includes:

[0049] S201. Control the upper computer to cache command frames to a preset frame cache queue from time to time; in the present invention, command frames can be divided into two categories: IO frames and other frames, IO frames: mainly used for IO queries and status interaction between the upper and lower computers; other frames: mainly used to perform quilting-related actions, including quilting frames and jumper frames. The quilting frame means taking a stitch, that is, moving the frame once and inserting a needle at the same time; the jumper frame means only moving the frame to the target position, but not inserting a needle. When the system is in standby mode, the bus communication between the upper computer and the lower computer mainly exchanges data in an asynchronous form. At this time, the upper computer caches other frames to the high-priority queue from time to time. If the high-priority sub-queue is not empty, other frames are sent first. If the high-priority sub-queue is empty, the IO frame is sent. The priority of sending the IO frame is lower than that of other frames. Figure 2 shown.

[0050] In an optional implementation of the first aspect of the present invention, step S201 may specifically include: determining whether the command frame is an IO frame; if the command frame is not the IO frame, caching the command frame to a high-priority sub-queue of the frame buffer queue; if the command frame is the IO frame, caching the command frame to a low-priority sub-queue of the frame buffer queue.

[0051] S202, control the host computer to take out a frame of the command frame from the frame buffer queue every first time, and send the command frame to the slave computer. In the present invention, when the quilting system is in standby state, the bus communication between the host computer and the slave computer, the synchronous thread is closed, the asynchronous thread is opened, the asynchronous thread is executed every 50ms, and the data is exchanged with the slave computer. At this time, the bus state of the quilting is as follows: Figure 3 shown.

[0052] S300, if the quilting system is currently in the quilting state, then based on the frame sending process and frame sending type of the pattern linked list, the bus communication between the upper computer and the lower computer is controlled to dynamically match the synchronous form and the asynchronous form to perform command interaction, and the synchronous form is that the upper computer sends the command frame to the lower computer after receiving the interrupt signal sent by the lower computer. In the present invention, when the quilting system is in the quilting state, the upper computer has processed the quilting pattern into a pattern linked list, and the pattern linked list only contains quilting frames and jumper frames.

[0053] The bus communication between the upper computer and the lower computer changes dynamically according to the process: the quilting frame is added to the high priority queue and sent down in an asynchronous form. After the quilting frame is sent, the asynchronous thread is closed and the synchronous thread is opened; after the lower computer receives the quilting frame, the quilting spindle starts to rotate, and when the spindle angle exceeds 144°, a rising edge interrupt signal will be generated; after the upper computer receives the interrupt signal, it sends the remaining command frame data in sequence along the pattern linked list.

[0054] That is, in an optional implementation of the first aspect of the present invention, if the quilting system is currently in a quilting state, the bus communication between the upper computer and the lower computer is controlled based on the frame sending process and frame sending type of the pattern linked list to dynamically match the synchronous form and the asynchronous form to perform command interaction, including: controlling the upper computer to add the starting quilting frame in the pattern linked list to the high priority queue of the frame buffer queue, and sending it to the lower computer in the asynchronous form; after the starting quilting frame is sent, controlling the asynchronous form to be closed and opening the synchronous form at the same time; after the lower computer receives the starting quilting frame, controlling the quilting spindle to rotate, and when the quilting spindle angle exceeds the preset angle, controlling the lower computer to generate an interrupt signal and sending the interrupt signal to the upper computer; after the upper computer receives the interrupt signal, sending the remaining command frames to the lower computer in sequence according to the pattern linked list.

[0055] In the first aspect of the present invention, during the process of the upper computer sending command frame data to the lower computer along the pattern list, if the upper computer sends a quilting frame, then 5ms after the quilting frame is sent, an IO frame will be sent again, and the process is always in a synchronous state; if a jumper frame is sent, then after the jumper frame is sent, an asynchronous thread will be opened to send IO frames in a loop, and the process is a coexistence of synchronization and asynchronous; after the jumper is completed, an interrupt signal will be generated, and after the upper computer receives the interrupt signal, the asynchronous thread will be closed; after waiting for 20ms, data will continue to be sent along the pattern list, and the process is in a synchronous state. The bus status during quilting is as follows: Figure 4 shown.

[0056] That is, in an optional implementation manner of the first aspect of the present invention, after the upper computer receives the interrupt signal, sending the remaining command frames to the lower computer in sequence according to the pattern linked list includes:

[0057] If the type of the command frame sent by the upper computer to the lower computer according to the pattern linked list is a quilting frame, then after the second time of sending the quilting frame, the upper computer is controlled to send the IO frame to the lower computer once, wherein the upper computer is in an asynchronous form when sending the quilting frame and the IO frame to the lower computer.

[0058] If the type of the command frame sent by the upper computer to the lower computer according to the pattern linked list is a jump line frame, then after the jump line frame is sent, the upper computer is controlled to send a cyclic IO frame to the lower computer, wherein the upper computer is in the asynchronous form when sending the jump line frame to the lower computer, and the upper computer is in a coexistence of the asynchronous form and the synchronous form when sending the IO frame to the lower computer.

[0059] When the jumper is completed, the lower computer is controlled to generate the interrupt signal and send the interrupt signal to the upper computer; when the upper computer receives the interrupt signal, the asynchronous form between the upper computer and the lower computer is closed, and after waiting for the third time, the upper computer is controlled to continue to send the remaining command frames to the lower computer in sequence according to the pattern list. The method of sending the remaining command frames can refer to the method in which the upper computer sends the remaining command frames to the lower computer in sequence according to the pattern list, and the first aspect of the present invention will not be repeated here. The bus communication control of the quilting system of the present invention has been successfully applied to the quilting system independently developed by the company. At the end customer, the system has been able to operate maturely and stably.

[0060] In general, the bus communication control method of the quilting system provided by the present invention, when the quilting system is currently in the standby state, will control the bus communication between the upper computer and the lower computer to perform command interaction in an asynchronous form; when the quilting system is currently in the quilting state, it will control the bus communication between the upper computer and the lower computer to dynamically match the synchronous form and the asynchronous form to perform command interaction based on the frame sending process and frame sending type of the pattern linked list. The quilting system of the present invention can flexibly adjust the bus communication mode when it is in different states, especially after the quilting system enters the quilting state, the bus communication mode between the upper and lower computers is reasonably adapted according to the process of sending command frames in the pattern linked list and the type of command frames, thereby ensuring the reliability of command frame transmission between the upper and lower computers, thereby improving the quilting quality of the quilting system.
