[0052] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0053] Figure 1 A schematic diagram of a human-machine interface 100 according to an embodiment of the present invention is shown below. Figure 1 Provide a detailed description.

[0054] like Figure 1 As shown, the human-machine interface 100 includes a communication module 110, a control module 120, a light driving module 130, and multiple light-emitting elements 140 (in this embodiment, 56 light-emitting elements 140 are used as an example). The communication module 110 is coupled to the control module 120, the control module 120 is coupled to the light driving module 130, and the light driving module 130 is coupled to the multiple light-emitting elements 140. The light-emitting elements 140 can be, for example, LED beads.

[0055] The communication module 110 may include a wired interface and / or a wireless interface. The wired interface may be RS-232, RS-485, Ethernet, etc., suitable for applications requiring high reliability and real-time performance, providing a stable data transmission channel to ensure timely and accurate transmission of device status information. The wireless interface may be Wi-Fi, Bluetooth, ZigBee, etc., suitable for scenarios where cabling is inconvenient or flexible deployment is required, enabling wireless communication between devices, simplifying system cabling, and improving system scalability and flexibility. The communication module 110 is configured to receive status information from associated devices. Associated devices refer to devices or ports that are directly or indirectly connected to the human-machine interface 100, including but not limited to various mechanical equipment on industrial automated production lines, automated sorting equipment in warehousing and logistics, and home appliances in smart home systems. These devices connect to the communication module 110 of the human-machine interface 100 via wired or wireless means and transmit their own status information to the human-machine interface 100 for further processing and display.

[0056] The control module 120 can be a central processing unit (CPU), or other types of processors or controllers; the present invention does not limit its specific type. The control module 120 is configured to determine the light emission state parameters based on the status information of the associated device and a preset mapping relationship, and output the light emission state parameters to the light driving module 130. The mapping relationship can take various forms such as program code, configuration files, and mapping tables, and its content covers the correspondence between the status information of the associated device and the light emission state parameters. Taking the mapping relationship implemented using program code as an example, the control module 120 can take the status information of the associated device as input, run the corresponding program code, and thus obtain the corresponding light emission state parameters. The light driving module 130 is configured to drive at least one light-emitting element 140 according to the light emission state parameters. The light emission state of these light-emitting elements 140 can intuitively reflect the working status of the associated device, allowing the user to determine the working status of the associated device without having to approach the human-machine interface 100.

[0057] According to one embodiment of the present invention, such as Figure 1 As shown, the light emission status parameters may include one or more of the following: light emission color, light emission brightness, light emission color temperature, light emission mode, and the number of light-emitting elements 140 that need to be lit. Light emission modes may include, for example, flashing mode, constant light mode, breathing mode, flowing mode (marquee), sequential lighting mode, etc. Combinations of various types of light emission status parameters can enrich the expression of the light-emitting elements 140, thereby more accurately reflecting the working status of associated devices and providing users with more intuitive information. At the same time, it can also make the human-machine interface 100 more visually appealing, stylish, and luxurious.

[0058] According to one embodiment of the present invention, such as Figure 1 As shown, the status information of the associated device includes digital information and / or analog information.

[0059] Digital information can include power-on information, power-off information, standby information, operating information, and fault alarm information. Operating information indicates the operating stage of the associated device, such as the preheating stage, normal operation stage, or high-speed operation stage. Those skilled in the art will understand that each type of digital information can have corresponding light emission state parameters. Different digital information corresponds to different light emission state parameters, and operating information indicating different operating stages corresponds to different light emission state parameters. This allows users to accurately determine the operating status of the associated device based on the light emission state of the light-emitting element 140, avoiding misreading. For example: the light emission status parameters corresponding to the power-on information are "light emission color - green, light emission brightness - 30mcd, light emission mode - flowing mode, number of 140 light emission elements to be lit - 56"; the light emission status parameters corresponding to the standby information are "light emission color - yellow, light emission brightness - 30mcd, light emission mode - constant light mode, number of 140 light emission elements to be lit - 56"; the light emission status parameters corresponding to the fault alarm information are "light emission color - red, light emission brightness - 50mcd, light emission mode - flashing mode, number of 140 light emission elements to be lit - 56".

[0060] Analog signals can be continuously changing physical or electrical quantities such as temperature, pressure, flow rate, speed, voltage, and current. These signals are typically collected by sensors in associated devices and converted into electrical signals, then transmitted to the human-machine interface 100 for processing and display. In some embodiments, the control module 120 can focus on only one or more analog signals preset by the user and control the light-emitting element 140's illumination state accordingly. It should be noted that for scenarios requiring monitoring of multiple analog signals, the multiple light-emitting elements 140 can be divided into multiple groups, and the control module 120 can control a corresponding group of light-emitting elements 140 for each type of analog signal. For example, in a chemical production scenario, the user may simultaneously monitor the temperature and pressure inside the reactor. In this case, the light-emitting elements 140 can be divided into two groups, each corresponding to one type of analog signal. The control module 120 controls the luminous state of a group of light-emitting elements 140 based on temperature changes, ensuring that the luminous state of this group of light-emitting elements 140 accurately reflects the temperature changes within the reactor. Simultaneously, the control module 120 can also control the luminous state of another group of light-emitting elements 140 based on pressure changes, ensuring that the luminous state of this group of light-emitting elements 140 accurately reflects the pressure changes within the reactor. Preferably, the luminous state parameters corresponding to the analog quantity information include the number of light-emitting elements 140 that need to be lit, wherein the value of the analog quantity information is positively correlated with the number of light-emitting elements 140 that need to be lit; for example, the higher the temperature within the reactor, the more light-emitting elements 140 need to be lit.

[0061] Figure 2A schematic diagram of a human-machine interface 100 according to an embodiment of the present invention is shown, as follows: Figure 2 As shown, the human-machine interface 100 may further include a display screen 150, and the plurality of light-emitting elements 140 are disposed on at least one side of the display screen 150. Preferably, the plurality of light-emitting elements 140 are disposed at intervals around the perimeter of the display screen 150. Figure 2 (Top, bottom, left, and right sides of the display screen 150). This layout not only provides clear visual indications but also allows users to observe the device's status from different angles, improving the user's visual experience. In a specific embodiment, the light-emitting elements 140 located on the same side of the display screen 150 can be grouped together, and their light-emitting state can be controlled by the control module 120 according to the corresponding analog signal information.

[0062] According to one embodiment of the present invention, such as Figure 1 As shown, the control module 120 is also configured to determine and output light emission status parameters based on the status information of the human-machine interface 100 and a preset mapping relationship. The mapping relationship includes the correspondence between the status information of the human-machine interface 100 and the light emission status parameters. The status information of the human-machine interface 100 may include, for example, power-on information, power-off information, and fault alarm information. Those skilled in the art will understand that each status information of the human-machine interface 100 can have corresponding light emission status parameters, and different status information corresponds to different light emission status parameters. It should be noted that the same status information of the human-machine interface 100 and the associated device can correspond to the same or different light emission status parameters. For example, the light emission status parameters corresponding to the power-on information of the human-machine interface 100 are different from those corresponding to the power-on information of the associated device. The light emission status parameters corresponding to the power-on information of the human-machine interface 100 are: "Light emission color - green, light emission brightness - 30 mcd, light emission mode - flashing mode, number of light-emitting elements 140 to be lit - 56".

[0063] According to one embodiment of the present invention, such as Figure 1As shown, the human-machine interface 100 may further include a real-time clock module 160 (RTC), which is configured to provide current time information (i.e., provide the current time). A control module 120 is coupled to the real-time clock module 160 and is further configured to determine and output illumination state parameters based on the time information and a preset mapping relationship. The mapping relationship includes the correspondence between time information and illumination state parameters. In some embodiments, a day can be divided into multiple time periods, each of which can be assigned corresponding illumination state parameters. The illumination state parameters for different time periods are different, allowing the user to determine the current time based on the illumination state of the illumination element 140, creating an atmosphere that matches the time period. For example, 0-9 can be set as a time period with the following light emission parameters: "Emission color - yellow, illumination brightness - 30mcd, illumination mode - breathing mode"; 9-17 can be set as a time period with the following light emission parameters: "Emission color - white, illumination brightness - 50mcd, illumination mode - breathing mode"; 17-24 can be set as a time period with the following light emission parameters: "Emission color - orange, illumination brightness - 30mcd, illumination mode - breathing mode".

[0064] The above describes in detail how the control module 120 determines the light emission state parameters based on a preset mapping relationship and the status information of the associated device, the status information of the human-machine interface, or the current time information, and the light driving module 130 drives at least one light-emitting unit 140. Those skilled in the art will readily understand that the status information of the associated device, the status information of the human-machine interface, and the current time information can be set to different priorities. When multiple pieces of information exist simultaneously, the control module can determine the light emission state parameters based on the information with higher priority to reflect the most important information.

[0065] According to one embodiment of the present invention, such as Figure 1 As shown, the human-machine interface 100 may further include a storage module 170, which is configured to store the mapping relationship. The control module 120 is coupled to the storage module 170 and configured to read the mapping relationship.

[0066] Figure 3 A schematic diagram of a human-machine interface 100 connected to a host computer 200 according to an embodiment of the present invention is shown, as follows: Figure 3As shown, the host computer 200 includes an editing module 210 and a communication module 220, which are coupled together. The editing module 210 provides an interface and can generate new mapping relationships or modification information for modifying mapping relationships based on user input on the interface. The communication module 220 of the host computer 200 is communicatively connected to the communication module 110 of the human-machine interface 100, and the communication module 220 can transmit the mapping relationships and modification information generated by the editing module 210 to the communication module 110.

[0067] According to one embodiment of the present invention, such as Figure 3 As shown, the communication module 110 can be configured to receive mapping relationships, and correspondingly, the control module 120 is configured to write the mapping relationships received by the communication module 110 into the storage module 170. The communication module 110 can also be configured to receive modification information, and correspondingly, the control module 120 is configured to modify the mapping relationships stored in the storage module 170 according to the modification information. This design allows users to flexibly update or modify mapping relationships according to actual needs, adapting to different application scenarios and user preferences, thus enhancing the adaptability of the human-machine interface 100 and the user experience.

[0068] According to one embodiment of the present invention, such as Figure 1 As shown, the human-machine interface 100 may also include an interactive button 180, which can be a physical button or a virtual button; the present invention does not specifically limit this. The control module 120 can be configured to generate a new mapping relationship based on the input information from the interactive button 180 and write it to the storage module 170. Optionally, the control module 120 can also be configured to modify the mapping relationship already stored in the storage module 170 based on the input information from the interactive button 180. This design allows users to directly update or modify the mapping relationship on the human-machine interface 100 according to actual needs, greatly improving ease of use.

The status information of associated devices includes digital and / or analog information. Digital information can include power-on information, power-off information, standby information, operating information, and fault alarm information. Operating information indicates the operating stage of the associated device, such as the preheating stage, normal operating stage, or high-speed operation stage. Analog information can be continuously changing physical or electrical quantities such as temperature, pressure, flow rate, speed, voltage, and current.

Emission modes may include, for example, flashing mode, constant light mode, breathing mode, flowing mode (marquee), and sequential illumination mode. The mapping relationship includes the correspondence between the status information of the associated device and the light emission status parameters. Specifically, the light emission status parameters corresponding to the analog quantity information include the number of light-emitting elements to be illuminated, and the value of the analog quantity information is positively correlated with the number of light-emitting elements to be illuminated.

Those skilled in the art will understand that each type of status information of the human-machine interface can have corresponding light emission status parameters, and different status information corresponds to different light emission status parameters. It should be noted that the same type of status information of the human-machine interface and the associated device can have the same or different light emission status parameters. For example, the light emission status parameters corresponding to the power-on information of the human-machine interface are different from those corresponding to the power-on information of the associated device. The light emission status parameters corresponding to the power-on information of the human-machine interface are: "Emission color - green, emission brightness - 30mcd, emission mode - flashing mode, number of light-emitting elements to be lit - 56".
