[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] The components of the embodiments of the invention described and illustrated herein can typically be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0032] In the following, the terms “comprising”, “having” and their cognates, which may be used in various embodiments of the invention, are intended only to indicate a particular feature, number, step, operation, element, component or combination thereof, and should not be construed as excluding, firstly, the presence of one or more other features, numbers, steps, operations, elements, components or combinations thereof, or the possibility of adding one or more features, numbers, steps, operations, elements, components or combinations thereof.

[0033] If the application documents contain similar descriptions such as "first, second, third", the following explanation shall be added: In the following description, the terms "first, second, third" are used only to distinguish similar objects and do not represent a specific order of objects. It is understood that "first, second, third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0034] Unless otherwise specified, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which the various embodiments of the invention pertain. Terms (such as those defined in commonly used dictionaries) shall be interpreted as having the same meaning as in their contextual meaning in the relevant technical field and shall not be interpreted as having an idealized or overly formal meaning, unless clearly defined in the various embodiments of the invention.

[0035] In one embodiment, such as Figure 1 As shown, a microcontroller-based tile production line control system is provided. This microcontroller-based control system includes a tile production line, an industrial computer 10, a host computer 20, a microcontroller 30, and an emergency stop knob 40. The industrial computer 10 is communicatively connected to the tile production line, the host computer 20, and the microcontroller 30. The industrial computer 10 is configured to control the tile production line to run according to a preset program and to receive external input commands to change the operating status of the tile production line. The host computer 20 is configured to acquire and display the current detection images of the tile production line in real time from the industrial computer 10. The microcontroller 30 is communicatively connected to the emergency stop knob 40 and is configured to output a control signal to the host computer 20 based on whether the emergency stop knob 40 is triggered. The host computer 20 displays the current detection image interface based on the control signal.

[0036] The tile production line includes at least a tile manufacturing stage and a tile sorting stage. In the tile sorting stage, tiles are sorted according to preset parameters. These preset parameters include one or a combination of color number, flatness, pattern, grade, and serial number. For example, when sorting tiles according to color number in the tile sorting stage, the monitoring interface of the tile production monitoring software on the host computer 20 is randomly paused, causing the image of the currently inspected tile to remain displayed on the host computer 20's monitoring interface. At this time, the image of the currently inspected tile can be compared with the image of the standard color number through manual comparison or software algorithm, thereby achieving sampling testing of the tile color separation process.

[0037] The host computer 20 can display the real-time inspection image of the currently sorted tiles on its screen. The host computer 20 can be a computer, mobile phone, or tablet. The host computer 20 and the industrial control computer 10 can communicate via wired or wireless connection. For example, the channel between the host computer 20 and the industrial control computer 10 is connected via Ethernet cable, which is suitable for long-distance communication between the monitoring room and the production line, with fast and stable transmission speed.

[0038] The emergency stop knob 40 can be used to manually trigger an interrupt event. Specifically, when the emergency stop knob 40 is pressed, an external signal is generated and transmitted to the microcontroller 30, causing a change in the voltage level on the I / O port connected to the microcontroller 30 and the emergency stop knob 40. The microcontroller 30 detects the voltage level on the I / O port and sends the detected voltage signal to its internal processing logic or application for further processing, thereby triggering the interrupt service routine (ISR) and outputting a control signal to the host computer 20. The host computer 20 then displays the current tile detection image based on the control signal, ensuring that the host computer 20 can quickly stop the display interface during the necessary sampling test process in the tile production and sorting process.

[0039] It should be noted that the emergency stop knob 40 is a mechanical switch that controls the on / off state of the power supply by changing the connection state of the circuit. Typically, the emergency stop knob 40 is designed as a conspicuous red button and uses a spring-loaded mechanism. The emergency stop knob 40 usually contains one or more contacts. When the emergency stop knob 40 is pressed, these contacts will quickly separate, causing the circuit to break. After the emergency stop knob 40 is pressed, it needs to be manually reset by rotating or pulling. Therefore, based on the connection between the emergency stop knob 40 and the I / O of the microcontroller 30, the level state of the corresponding I / O port can be changed according to whether the emergency stop knob 40 is pressed.

[0040] This application discloses a microcontroller-based tile production line control system. By configuring a microcontroller 30 and an emergency stop knob 40, with the microcontroller 30 communicatively connected to both the emergency stop knob 40 and a host computer 20, the microcontroller 30 can quickly respond to the input signal and output a corresponding control signal when the emergency stop knob 40 is pressed. This, in turn, controls the software detection interface of the host computer 20 to pause and display the current tile's detection image. This application utilizes the emergency stop knob 40 to input external signals to the microcontroller 30's I / O port, enabling the microcontroller 30 to quickly respond to the input signal from the emergency stop knob 40. This eliminates the need for complex external components, resulting in low system implementation costs. Furthermore, in high-speed production lines, workers can quickly pause the host computer 20 interface to observe the currently detected tile data, making the system suitable for scenarios in tile production lines with high requirements for emergency stop functionality.

[0041] In some embodiments, the emergency stop knob 40 and the microcontroller 30 communicate via an external I / O interrupt input and a data bus connection.

[0042] In some embodiments, an optocoupler is provided in the communication connection between the emergency stop knob 40 and the microcontroller 30.

[0043] The microcontroller-based tile production line control system in the above embodiments further specifies that the emergency stop knob 40 is connected to the microcontroller 30 via an optocoupler. Based on the above design, the optocoupler can isolate the electromagnetic interference received by the emergency stop knob 40 in industrial environments. Moreover, the optocoupler can quickly respond to the input signal of the emergency stop knob 40 and feed it back to the microcontroller 30, ensuring that the microcontroller 30 can accurately and quickly respond to the input signal of the emergency stop knob 40 and output the corresponding control signal.

[0044] In some embodiments, the microcontroller 30 includes a debounce module, which includes a function to perform debounce processing on the signal transmission between the emergency stop knob 40 and the microcontroller 30.

[0045] The microcontroller-based tile production line control system in the above embodiments further defines the de-jitter module to perform de-jitter processing on the transmitted signal during the signal transmission process between the microcontroller 30 and the emergency stop knob 40 or the host computer 20, filtering unstable signals to ensure the reliable operation of the system.

[0046] In some embodiments, the host computer 20 is further configured to convert the control signal to obtain a control conversion signal and transmit it to the industrial computer 10. The industrial computer 10 displays the interface of the currently detected image according to the control conversion signal.

[0047] The microcontroller-based tile production line control system in the above embodiment further defines that the controller in the host computer 20 receives the control signal transmitted by the microcontroller 30, converts it, and outputs the control conversion signal to the tile production monitoring software, so that the detection interface of the monitoring software stays on the detection image of the currently detected tile.

[0048] It should be noted that, in the actual production process of tiles, the production line speed can reach up to 90m per minute, and the detection interface on the tile production monitoring software in the host computer 20 is also switching rapidly. When production line workers need to pause the host computer 20 interface to observe the data, they need to use the rapid response function.

[0049] In some embodiments, the microcontroller 30 is also configured to output control signals to the industrial computer 10, and the industrial computer 10 displays the interface of the currently detected image according to the control signals.

[0050] The microcontroller-based tile production line control system in the above embodiments further defines the industrial control computer 10 as capable of receiving control signals output by the microcontroller 30, thereby keeping the display screen of the industrial control computer 10 on the image interface of the currently inspected tile. Compared to using a USB mouse or touchscreen for control of the industrial control computer 10, this application, through the cooperation of the microcontroller 30 and the emergency stop knob 40, can achieve remote control of the industrial control computer 10's display screen to keep displaying the image interface of the currently inspected tile, and it is low in cost and has a fast response speed.

[0051] In some embodiments, the host computer 20 is further configured to receive an unlock signal released by the microcontroller 30 to release the display of the currently detected image interface.

[0052] The microcontroller-based tile production line control system in the above embodiments further defines the working state of the emergency stop knob 40 to enable locking or unlocking of the monitoring interface of the tile production monitoring software.

[0053] The unlock signal can be a level change signal of the IO port connected to the microcontroller 30 and the emergency stop knob 40. For example, when the emergency stop knob 40 is pressed, it triggers the microcontroller 30 to output a control signal. When the emergency stop knob 40 is manually or automatically reset, the level of the IO port connected to the microcontroller 30 and the emergency stop knob 40 changes again, thereby triggering the microcontroller 30 to output an unlock signal to the host computer 20 to unlock the monitoring interface of the tile production monitoring software on the host computer 20.

[0054] In some embodiments, when the host computer 20 writes an unlock input command, the display of the currently detected image interface is deactivated.

[0055] The "write unlock input command" on the host computer 20 refers to the user manually unlocking the tile production monitoring software. For example, the user can unlock the display interface of the currently detected tile image by clicking the mouse or entering the command on the keyboard.

[0056] like Figure 2 As shown, this application also provides a microcontroller-based control method for a ceramic tile production line. This method is used to control the aforementioned microcontroller-based ceramic tile production line control system. The control method includes the following steps:

[0057] Step S200: Initialize the microcontroller 30 and configure the host computer 20 to obtain and display the detection images of the current tile production line in real time from the industrial control computer 10;

[0058] Step S400: Based on the register detection of the microcontroller's internal system, the level of the IO port connected to the emergency stop knob 40 is detected. When the change in the IO port level meets the triggering condition, the microcontroller 30 outputs a control signal to the host computer 20.

[0059] In step S600, the host computer 20 pauses on the interface displaying the currently detected image based on the received control signal.

[0060] The microcontroller-based tile production line control method provided in this application determines whether the microcontroller 30 should output a control signal to the host computer 20 to control the tile production monitoring software's detection interface to remain displayed by real-time detection of the level changes of the I / O port connected to the microcontroller 30 and the emergency stop knob 40. Specifically, by initializing the microcontroller 30 and setting the trigger conditions for its output control signal, when the emergency stop knob 40 is pressed, the level change of the I / O port meets the trigger conditions. At this time, the microcontroller 30 loads an interrupt service routine and outputs a control signal to the host computer 20, thereby controlling the tile production monitoring software's detection interface to remain displayed. This control method, based on the microcontroller's I / O port, enables real-time detection and rapid response to the emergency stop knob 40, and triggers the interrupt service routine (ISR) to output control signals to control the detection interface of the tile production monitoring software, meeting the control requirements of tile production line control scenarios with high demands for emergency stop functionality.

[0061] In some embodiments, the specific steps for initializing the microcontroller 30 include: setting the IO port connected to the emergency stop knob 40 to input mode; and setting the IO port level state change conditions for triggering the output control signal.

[0062] The I / O ports of the microcontroller 30 can be configured as either input or output modes. In input mode, the I / O ports are used to receive external signals. In this embodiment, the I / O ports of the microcontroller 30 connected to the emergency stop knob 40 are configured as input modes. In input mode, the microcontroller 30 typically detects the level state of the I / O ports through its internal registers.

[0063] The condition for triggering the output control signal can be determined based on the change in the I / O port level. For example, when the I / O port level is low, the microcontroller 30 outputs a control signal. Specifically, when the emergency stop knob 40 is pressed, the I / O port connected to the emergency stop knob 40 changes from high to low. The microcontroller 30 sends the detected level signal to its internal processing logic or application for further processing, thereby triggering the interrupt service routine and generating a control signal that can control the display on the monitoring interface of the tile production monitoring software.

[0064] like Figure 3 As shown, in some embodiments, step S800 is included after step S600: when the microcontroller 30 receives an unlock signal or the host computer 20 writes an unlock input command, the display of the current detection image interface is deactivated.

[0065] The unlock signal can be generated based on the change in the working state of the emergency stop knob 40. Specifically, when the emergency stop knob 40 is pressed and then manually or automatically reset, the level of the IO port connected to the microcontroller 30 and the emergency stop knob 40 changes from low to high, thereby triggering the microcontroller 30 to output an unlock signal to the host computer 20, so as to unlock the monitoring interface of the tile production monitoring software on the host computer 20.

[0066] The unlock input command written to the host computer 20 can be used by the user to directly unlock the monitoring interface of the tile production monitoring software on the host computer 20 by clicking with the mouse or entering the command with the keyboard.

[0067] It should be understood that, although Figure 2-3 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figure 2-3 At least some of the steps in the process may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.

[0068] This application also provides a computer-readable storage medium storing a computer program that, when executed, can implement the above-described microcontroller-based ceramic tile production line control method.

[0069] In one example, when a computer program is executed, it performs the following steps:

[0070] Step S200: Initialize the microcontroller 30 and configure the host computer 20 to acquire and display the current inspection image of the tile production line in real time from the industrial control computer 10; Step S400: Based on the register inside the microcontroller, detect the level status of the IO port connected to the emergency stop knob 40. When the change in the IO port level status meets the trigger condition, the microcontroller 30 outputs a control signal to the host computer 20; Step S600: The host computer 20 stays on the interface displaying the current inspection image according to the received control signal.

[0071] Those skilled in the art will understand that all or part of the processes in the methods of the above embodiments can be implemented by a computer program instructing related hardware. The computer program can be stored in a non-volatile computer-readable storage medium, and when executed, it can include the processes of the embodiments of the above methods.

Non-volatile memory can include read-only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable programmable ROM (EEPROM), or flash memory. Volatile memory can include random access memory (RAM) or external cache memory. By way of illustration and not limitation, RAM is available in various forms, such as static RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), dual data rate SDRAM (DDRSDRAM), enhanced SDRAM (ESDRAM), synchronous link DRAM (SLDRAM), Rambus direct RAM (RDRAM), direct memory bus dynamic RAM (DRDRAM), and memory bus dynamic RAM (RDRAM), etc.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
