Description

Technical Field

[0001] The present invention relates to the technical field of human-computer interaction, and in particular to a control method for a human-computer interface device, a control device for a human-computer interface device, and a human-computer interface device. Background Art

[0002] In the related art, among many simple human-machine interface forms, three-button control + multi-digit digital tube display is a relatively classic combination. When using this type of human-machine interface form to display parameters, if there are many parameters displayed, it is easy to cause difficulty in parameter search and frequent switching operations, thus causing many inconveniences in use. Summary of the invention

[0003] In order to solve at least one of the above technical problems, a first objective of the present invention is to provide a control method for a human-machine interface device.

[0004] The second object of the present invention is to provide a control device for a human-machine interface device.

[0005] The third object of the present invention is to provide a human-machine interface device.

[0006] In view of this, according to an embodiment of the first aspect of the present invention, the present invention proposes a control method for a human-machine interface device, the human-machine interface device is used to connect to an electrical device, and the control method includes: when a display device of the human-machine interface device displays a first content, the first content includes a first type of working parameter of the electrical device; receiving a first input from a user to a first button of the human-machine interface device, switching the content displayed by the display device to a second content, the second content includes a second type of working parameter of the electrical device; receiving a second input from the user to the first button, switching the content displayed by the display device to the first content; wherein the first type of working parameters includes multiple working parameters whose historical call frequencies are greater than or equal to a first frequency threshold, and the second type of working parameters includes multiple working parameters whose historical call frequencies are less than the first frequency threshold.

[0007] In the control method of the human-machine interface device proposed in the present invention, the human-machine interface device controlled by the control method is used to connect with the electrical equipment. After the human-machine interface device is connected with the electrical equipment, the human-machine interface device can establish a connection with the electrical equipment to input and output information. For example, the electrical equipment will generate a variety of working parameters during operation, and the human-machine interface device can display these working parameters. The user can also operate the human-machine interface device and transmit the adjustment information to the electrical equipment through the human-machine interface device, thereby indirectly realizing the adjustment of the electrical equipment.

[0008] It should be noted that the execution subject of the control method of the human-machine interface device proposed in the present invention may be the control device of the human-machine interface device. In order to more clearly illustrate the control method of the human-machine interface device proposed in the present invention, the following technical scheme uses the execution subject of the control method of the human-machine interface device as an example of the control device of the human-machine interface device.

[0009] The control method includes: when a display device of a human-machine interface device displays a first content, the first content includes a first type of operating parameter of an electrical device. When the human-machine interface device is turned on, the human-machine interface device can display the first content, and the first content includes a first type of operating parameter of the electrical device. Specifically, the first type of operating parameter includes a plurality of operating parameters whose historical call frequency is greater than or equal to a first frequency threshold, so that a commonly used operating parameter can be displayed to the user when the device is turned on, which is convenient for the user to use and avoids the user having to switch multiple times before being able to see the commonly used operating parameters when the human-machine interface device is turned on.

[0010] Further, upon receiving a first input from a user to a first button of a human-machine interface device, in response to the first input to the first button, the content displayed by the display device is switched to a second content, and the second content includes a second type of operating parameter of the electrical device. Specifically, the second type of operating parameter includes a plurality of operating parameters whose historical call frequencies are less than the first frequency threshold. That is, the display device changes from displaying a first type of operating parameter to displaying a second type of operating parameter, so that the user can easily view an infrequently used operating parameter.

[0011] Furthermore, when receiving the second input of the user to the first button, the content displayed by the display device is switched to the first content, that is, the display device changes from displaying a second type of operating parameter to displaying a first type of operating parameter.

[0012] It is understandable that the human-machine interface device can obtain multiple working parameters of the electrical equipment, and classify different working parameters according to the frequency of users viewing different working parameters, that is, the historical call frequency, and integrate multiple working parameters with a historical call frequency greater than or equal to the first frequency threshold as a set, namely the first type. Multiple working parameters with a historical call frequency less than the first frequency threshold are integrated together as another set, namely the second type. When the user repeats the above-mentioned process of performing the first input and the second input on the first button, the content displayed by the display device will switch between the first content and the second content accordingly, so that the user can directly see the commonly used working parameters, and can also quickly view the uncommon working parameters when they need to view or use uncommon working parameters, thereby improving the convenience of parameter search and avoiding many inconveniences caused by cumbersome switching.

[0013] In addition, the control method of the human-machine interface in the above embodiment provided by the present invention may also have the following additional technical features:

[0014] In the above technical solution, the control method further includes: receiving a third input from the user to the first button, switching the content displayed by the display device to a third content, and the third content includes another first type of operating parameter of the electrical device.

[0015] In this technical solution, when the human-machine interface device is turned on, the human-machine interface device can display the first content, and when the display device displays the first content, the control method also includes receiving a third input from the user to the first button, switching the content displayed by the display device to the third content, and the third content includes another first-type working parameter of the electrical device. For example, when the display device displays a first-type working parameter, when the user makes a third input to the first button, in response to the third input, the display device adjusts the display content, and the displayed content becomes another first-type working parameter, so that the user can switch and search between multiple first-type working parameters. In the process of user switching and searching, the user searches among the working parameters whose historical call frequency is greater than or equal to the first frequency threshold, that is, the infrequently used working parameters are eliminated, and the user searches among the working parameters that were frequently used by the user before, so that the user can find the working parameters that need to be viewed or used faster, reducing the tediousness of the switching operation.

[0016] In any of the above technical solutions, the control method also includes: receiving a fourth input from the user on a second button of the human-machine interface device, determining a parameter attribute of the first type of working parameter; when the parameter attribute is the first attribute, increasing the value of the first type of working parameter according to a preset increase rate and a preset single increase value, and causing the display device to display the increase process.

[0017] In the technical solution, the control method further includes receiving a fourth input from a user to a second button of a human-machine interface device, and in response to the fourth input to the second button, determining the parameter attribute of the currently displayed first type of working parameter. Specifically, the second button is a button for adjusting a numerical value, wherein the second button is specifically used to increase the numerical value, and the fourth input is pressing the second button. The parameter attribute of the working parameter is a first attribute, and the first attribute specifically includes being unprotected or not requiring protection against human factors. The working parameter of such a parameter attribute is a working parameter that can be adjusted independently by the user. Correspondingly, the parameter attribute of the working parameter also includes a second attribute, and the second attribute specifically includes being protected or requiring protection against human factors. The working parameter of such a parameter attribute is more important to the operation of the electrical equipment, and under normal circumstances, certain adjustments are not allowed.

[0018] When it is determined that the parameter attribute is the first attribute, it means that the parameter can be adjusted, and the second button is a button for increasing the value, so the value of the first type of working parameter is increased according to the preset increase rate and the preset single increase value, and the display device displays the increase process. Specifically, the preset single increase value is one, and the preset increase rate is a dynamically changing value, which is related to the duration attribute of the fourth input and becomes faster as the duration increases.

[0019] For example, if the value of a first type of working parameter currently displayed is 50, and the duration attribute of the fourth input is 1 second, that is, the user presses the second button for 1 second, the preset increase rate is to increase by one preset single increase value per second, and the preset single increase value is 1, the display device will display 51. If the duration attribute of the fourth input is five seconds, that is, the user presses the second button for five seconds, it can be understood that the user has long pressed the second button, and the preset increase rate will reach two preset single increase values ​​per second at two seconds, three preset single increase values ​​per second at three seconds, four preset single increase values ​​per second at four seconds, and five preset single increase values ​​per second at five seconds. During the increase process, the display device displays 51 in the first second of pressing, 52 and 53 in sequence in the second second of pressing, 54, 55 and 56 in sequence in the third second of pressing, 57, 58, 59 and 60 in sequence in the fourth second of pressing, and 61, 62, 63, 64 and 65 in sequence in the fifth second of pressing, so as to clearly show the process of value adjustment to the user. There can be multiple relationships between the specific preset increase rate and the duration attribute of the fourth input, and the above description is only one of the cases, and the specific situation can be set according to user requirements.

[0020] Specifically, the preset increase rate increases with time until the maximum increase rate value allowed is reached, and then the increase is performed according to the maximum increase rate value. In addition, if the operating parameter has reached its maximum allowed value, the increase is automatically stopped.

[0021] By making the value of the preset increase rate gradually increase with time, the user can more conveniently modify the working parameter value.

[0022] In any of the above technical solutions, the control method also includes: receiving the fifth input of the user to the third button of the human-machine interface device, determining the parameter attribute of the first type of working parameter; when the parameter attribute is the first attribute, reducing the value of the first type of working parameter according to a preset reduction rate and a preset single reduction value, and causing the display device to display the reduction process.

[0023] In the technical solution, the control method further includes receiving a fifth input from a user to a third button of a human-machine interface device, and in response to the fifth input to the third button, determining the parameter attribute of the currently displayed first type of working parameter. Specifically, the third button is a button for adjusting a numerical value, wherein the third button is specifically used to reduce the numerical value, and the fifth input is pressing the third button. The parameter attribute of the working parameter is a first attribute, and the first attribute specifically includes being unprotected or not requiring protection against human factors. The working parameter of this parameter attribute is a working parameter that can be adjusted independently by the user. Correspondingly, the parameter attribute of the working parameter also includes a second attribute, and the second attribute specifically includes being protected or requiring protection against human factors. The working parameter of this parameter attribute is more important to the operation of the electrical equipment, and under normal circumstances, certain adjustments are not allowed.

[0024] When it is determined that the parameter attribute is the first attribute, it means that the parameter can be adjusted, and the third button is a button for decreasing the value, so the value of the first type of working parameter is decreased according to the preset decrease rate and the preset single decrease value, and the display device displays the decrease process. Specifically, the preset single decrease value is one, and the preset decrease rate is a dynamically changing value, which is related to the duration attribute of the fifth input and becomes faster as the duration increases.

[0025] For example, if the value of a first type of working parameter currently displayed is 50, the duration attribute of the fifth input is one second, that is, the user presses the third button for one second, the preset reduction rate is to reduce by one preset single reduction value per second, and the preset single reduction value is one, the display device will display 49. If the duration attribute of the fifth input is five seconds, that is, the user presses the third button for five seconds, it can be understood that the user has long pressed the third button, then the preset reduction rate will reach two preset single reduction values ​​per second at two seconds, three preset single reduction values ​​per second at three seconds, four preset single reduction values ​​per second at four seconds, and five preset single reduction values ​​per second at five seconds. During the reduction process, the display device displays 49 in the first second of pressing, 48 and 47 in sequence in the second second of pressing, 46, 45 and 44 in sequence in the third second of pressing, 43, 42, 41 and 40 in sequence in the fourth second of pressing, and 39, 38, 37, 36 and 35 in sequence in the fifth second of pressing, so as to clearly show the user the process of value adjustment. There can be many specific relationships between the preset reduction rate and the duration attribute of the fifth input, and the above description is only one of the cases, and the specific situation can be set according to user requirements.

[0026] Specifically, the preset reduction rate increases with time until the maximum reduction rate value allowed is reached, and then the reduction is performed according to the maximum reduction rate value. In addition, if the operating parameter has reached its minimum allowed value, the reduction is automatically stopped.

[0027] By making the value of the preset reduction rate gradually decrease with the increase of time, the user can more conveniently modify the working parameter value.

[0028] In any of the above technical solutions, the control method also includes: when a problem parameter is detected, switching the display content of the display device to a fourth content, the fourth content including at least one alarm prompt information; receiving a sixth input from the user to a second button of the human-machine interface device and a seventh input to a third button of the human-machine interface device at the same time, and switching the content displayed by the display device to the first content.

[0029] In this technical solution, during the operation of the electrical equipment, a plurality of working parameters will be self-checked, and when a problematic parameter is detected during the self-check, the human-machine interface device in a state of continuously acquiring the problematic parameter will acquire the problematic parameter. When the problematic parameter is detected, the display content of the switching display device is changed to the fourth content, and the fourth content includes at least one alarm prompt information, so as to remind the user that the current electrical equipment has a problem and needs to be repaired and debugged.

[0030] When simultaneously receiving the fifth input from the user on the second button of the human-machine interface device and the seventh input from the user on the third button of the human-machine interface device, the control device of the human-machine interface device responds accordingly, deeming that the user is aware of the alarm prompt information and no longer needs to view the alarm prompt information, and switches the content displayed by the display device to the first content, and displays the first type of working parameters normally.

[0031] By setting the display of alarm prompt information, the risk of users ignoring problems with electrical equipment can be reduced, and the normal operation of electrical equipment can be better guaranteed. In addition, the alarm prompt information is eliminated only when the input control of the second button and the third button is received at the same time, and the normal first type of working parameter display is performed, which can avoid the situation where the alarm prompt information is eliminated due to accidental touch.

[0032] In any of the above technical solutions, the control method also includes: receiving a third input from a user on a first button of a human-machine interface device, switching the content displayed by the display device to a fifth content, the fifth content including display function parameters; receiving a fourth input from a user on a second button of the human-machine interface device, turning on a parked display mode; receiving a first input from a user on a first button, switching the content displayed by the display device to a second content, the second content including a second type of working parameter of the electrical equipment; and locking the displayed content of the display device to the second content.

[0033] In the technical solution, the control method further includes: receiving a third input of the user to the first button of the human-machine interface device, specifically, the third input is a short press of the first button. In the case of receiving the third input of the user to the first button of the human-machine interface device, the content displayed by the switching display device is the fifth content, and the fifth content specifically includes a display function parameter, and the display function parameter is used to adjust the display mode of the human-machine interface device. Specifically, the display mode includes a return display mode and a stop display mode. After the human-machine interface device is turned on, the display mode defaults to the return display mode, and receiving the fourth input of the user to the second button of the human-machine interface device, it will be correspondingly switched from the return display mode to the stop display mode, that is, the stop display mode is turned on. Thereafter, if the user's first input to the first button is received, the content displayed by the switching display device is the second content, and the second content includes a second type of working parameter of the electrical device, and the content displayed by the locking display device is the second content, that is, the display device of the human-machine interface device is kept to continuously display the second content switched by the user, and will not jump back to display the first content when the user's operation instruction is not received. It is convenient for users to use.

[0034] In any of the above technical solutions, the content displayed by the locked display device is the second content, specifically including: making the display device display the parameter name of the second type of working parameter; after the display time reaches the first time, displaying the parameter value of the second type of working parameter; after the display time reaches the second time, displaying the parameter name of the second type of working parameter.

[0035] In the technical solution, the display content of the locking display device specifically includes: first, the display device displays the parameter name of the second type of working parameter, so that the user can know which parameter is currently displayed, and after the display time of the parameter value of the second type of working parameter reaches the first time, the parameter value of the second type of working parameter is displayed, so that the user can know the parameter value of the currently displayed parameter. After the display time of the parameter value of the second type of working parameter reaches the second time, the parameter name of the second type of working parameter will be displayed again, and the above process can be repeated multiple times for the convenience of user viewing.

[0036] In any of the above technical solutions, after switching the content displayed by the display device to the second content, the control method further includes: when the first input or the second input is not received within a third time period, switching the display content of the display device to the first content.

[0037] In this technical solution, after the content displayed by the display device is switched to the second content, a period of time will be left for the user to view and wait for the next input control of the user. If the first input or the second input is not received within the third period of time, it means that the user does not want to switch the operation, and the control device of the human-machine interface device will control the display device accordingly, switch the display content of the display device to the first content, and realize the reset of the display content. The above process is the return display mode.

[0038] In any of the above technical solutions, the first content specifically includes: a first type of working parameter that meets the priority display requirement; or a first type of working parameter that meets the user setting requirement.

[0039] In this technical solution, on the one hand, the first content specifically includes a first type of working parameter that meets the priority display requirements, wherein the priority display requirements include the one with the highest historical call frequency among the first type of working parameters, that is, among the many working parameters commonly used by the user, a parameter with the highest frequency of use is selected for display, thereby making it easier for users to directly view the working parameters they want to view most and view most frequently, avoiding complicated switching processes.

[0040] On the other hand, the first content specifically includes a first type of working parameter that meets the user's setting requirements, that is, the user can independently choose which parameter to display first after turning on the computer to better meet the user's usage needs.

[0041] In any of the above technical solutions, the control method also includes: receiving a third input from a user on a first button of the human-machine interface device, switching the display content of the display device to a sixth content, the sixth content including anti-human error function parameters; receiving a fifth input from a user on a third button of the human-machine interface device, and turning off the anti-human error function of the human-machine interface device.

[0042] In this technical solution, during the operation of the human-machine interface device, the anti-error function is enabled by default, and the value of the anti-error function parameter is 1. When the anti-error function is enabled, some commonly used working parameters with the second attribute, that is, protected working parameters, are not allowed to be modified, or some uncommon working parameters with the second attribute, that is, protected working parameters, are not displayed, so that the amount of working parameters that users view normally is reduced, which facilitates users to quickly find the working parameters they want to view.

[0043] When receiving the third input from the user to the first button, the display content of the display device is switched to the sixth content, and the sixth content includes an anti-human error function parameter; when receiving the fifth input from the user to the third button, the anti-human error function of the human-machine interface device is turned off, wherein the fifth input is pressing, and by pressing the third button, the value of the anti-human error function parameter is modified to zero, thereby turning off the anti-human error function of the human-machine interface device.

[0044] The anti-error function is turned off, thereby turning off the protection of commonly used working parameters with parameter attributes as the second attribute, and hiding the display of uncommon working parameters with parameter attributes as the second attribute, thereby meeting the user's various needs.

[0045] According to a second aspect of the present invention, a control device for a human-machine interface device is proposed, comprising a processor, a memory, and a program or instruction stored in the memory and running on the processor, wherein when the program or instruction is executed by the processor, the steps of a control method for a human-machine interface device as in any of the above-mentioned technical solutions are implemented.

[0046] The control device of the human-machine interface device proposed in the second aspect of the present invention implements the steps of the control method of the human-machine interface device in any of the above-mentioned technical solutions when the program or instructions are executed by the processor. Therefore, it has all the beneficial effects of the control method of the human-machine interface device in any of the above-mentioned technical solutions, which will not be repeated here.

[0047] According to a third aspect of the present invention, a human-machine interface device is proposed, comprising: a main body, used to connect with an electrical device, the main body being capable of obtaining a variety of operating parameters of the electrical device; a display tube, arranged on the main body and used to display the operating parameters; a first button, a second button and a third button, all arranged on the main body and linked with the display tube; and a control device for the human-machine interface device in the above technical solution.

[0048] The human-machine interface device proposed in the present invention includes a main body, which is used to connect with the electrical equipment. The main body can obtain various working parameters of the electrical equipment and realize data transmission between the human-machine interface device and the electrical equipment. The human-machine interface device also includes a display tube, which is arranged on the main body and is used to display the working parameters so that the user who uses the human-machine interface device can view the relevant working parameters. The human-machine interface device also includes a first button, a second button and a third button, which are all arranged on the main body and linked with the display tube. Specifically, the first button is a switching button, the second button is a value increase button, and the third button is a value decrease button. Through the above three buttons, it is possible to switch and view the working parameters displayed on the display tube and modify and adjust the working parameters displayed on the display tube.

[0049] The human-machine interface device also includes the control device of the human-machine interface device in the above technical solution. During the process of the control device of the human-machine interface device executing the control method of the human-machine interface device, the human-machine interface device can conveniently display different working parameters, reduce the tediousness of switching, and improve the user experience.

[0064] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0065] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0066] Refer to the following Figures 1 to 10 A method for controlling a human-machine interface device, an apparatus for controlling a human-machine interface device, and a human-machine interface device according to some embodiments of the present invention are described.

[0067] Figure 1 A flow chart of a control method of a human-machine interface device in one embodiment of the present invention is shown, wherein the control method comprises:

[0068] S102: When a display device of a human-machine interface device displays first content, the first content includes a first type of operating parameter of an electrical device;

[0069] S104: receiving a first input from a user on a first button of a human-machine interface device, and switching the content displayed by the display device to a second content;

[0070] S106: receiving a second input of the user to the first button, and switching the content displayed by the display device to the first content.

[0071] In the control method of the human-machine interface device proposed in the present invention, the human-machine interface device controlled by the control method is used to connect with the electrical equipment. After the human-machine interface device is connected with the electrical equipment, the human-machine interface device can establish a connection with the electrical equipment to input and output information. For example, the electrical equipment will generate a variety of working parameters during operation, and the human-machine interface device can display these working parameters. The user can also operate the human-machine interface device and transmit the adjustment information to the electrical equipment through the human-machine interface device, thereby realizing indirect adjustment of the electrical equipment.

[0072] It should be noted that the execution subject of the control method of the human-machine interface device proposed in the present invention may be the control device of the human-machine interface device. In order to more clearly illustrate the control method of the human-machine interface device proposed in the present invention, the following technical scheme uses the execution subject of the control method of the human-machine interface device as an example of the control device of the human-machine interface device.

[0073] The control method includes: when a display device of a human-machine interface device displays a first content, the first content includes a first type of operating parameter of an electrical device. When the human-machine interface device is turned on, the human-machine interface device can display the first content, and the first content includes a first type of operating parameter of the electrical device. Specifically, the first type of operating parameter includes a plurality of operating parameters whose historical call frequency is greater than or equal to a first frequency threshold, so that a commonly used operating parameter can be displayed to the user when the device is turned on, which is convenient for the user to use and avoids the user having to switch multiple times before being able to see the commonly used operating parameters when the human-machine interface device is turned on.

[0074] Specifically, when the display device of the human-machine interface displays, the display device first displays the parameter name of a first type of working parameter, and after an interval of a few seconds, displays the specific value of this first type of working parameter. By setting the display process of first displaying the name and then displaying the value, it is convenient for users to view and use.

[0075] Further, upon receiving a first input from a user to a first button of a human-machine interface device, in response to the first input to the first button, the content displayed by the display device is switched to a second content, and the second content includes a second type of operating parameter of the electrical device. Specifically, the second type of operating parameter includes a plurality of operating parameters whose historical call frequencies are less than the first frequency threshold. That is, the display device changes from displaying a first type of operating parameter to displaying a second type of operating parameter, so that the user can conveniently view an infrequently used operating parameter.

[0076] Specifically, the first input includes a long press, wherein the long press includes a press with a press duration greater than or equal to a first press duration threshold, and the first press duration threshold can be set according to user requirements.

[0077] Specifically, when the display device of the human-machine interface is displaying, the display device first displays the parameter name of a second type of working parameter, and after an interval of a few seconds, displays the specific value of this second type of working parameter. By displaying the name first and then the value, the display setting facilitates user viewing and use.

[0078] Furthermore, when receiving the second input of the user to the first button, the content displayed by the display device is switched to the first content, that is, the display device changes from displaying a second type of operating parameter to displaying a first type of operating parameter.

[0079] Specifically, the second input includes a long press, wherein the long press includes a press with a duration greater than or equal to the first press duration threshold. That is, the second input can be the same as the first input, and the control device of the human-machine interface device will make different switching reactions when receiving the same input to the first button according to the different display contents of the current display device. For example, when the display device displays the first content, the user's long press on the first button is received, and the content displayed by the display device is switched to the second content. When the user's long press on the first button is received again, the content displayed by the display device is switched to the first content. The switching between the first content and the second content can be performed multiple times, which is specifically determined by the number of times the user presses the first button, and then multiple working parameters are displayed in sequence.

[0080] It is understandable that the human-machine interface device can obtain multiple working parameters of the electrical equipment, and classify different working parameters according to the frequency of users viewing different working parameters, that is, the historical call frequency, and integrate multiple working parameters with a historical call frequency greater than or equal to the first frequency threshold as a set, namely the first type. Multiple working parameters with a historical call frequency less than the first frequency threshold are integrated together as another set, namely the second type. When the user repeats the above-mentioned process of performing the first input and the second input on the first button, the content displayed by the display device will switch between the first content and the second content accordingly, so that the user can directly see the commonly used working parameters, and can also quickly view the uncommon working parameters when they need to view or use uncommon working parameters, thereby improving the convenience of parameter search and avoiding many inconveniences caused by cumbersome switching.

[0081] Figure 2 A flow chart of a control method of a human-machine interface device in one embodiment of the present invention is shown, wherein the control method comprises:

[0082] S202: When a display device of a human-machine interface device displays first content, the first content includes a first type of operating parameter of an electrical device;

[0083] S204: receiving a third input from the user on the first button, and switching the content displayed on the display device to a third content.

[0084] In this embodiment, when the human-machine interface device is turned on, the human-machine interface device can display the first content, and when the display device displays the first content, the control method also includes receiving a third input from the user to the first button, switching the content displayed by the display device to the third content, and the third content includes another first-type operating parameter of the electrical device. For example, when the display device displays a first-type operating parameter, when the user makes a third input to the first button, in response to the third input, the display device adjusts the display content, and the displayed content becomes another first-type operating parameter, so that the user can switch and search between multiple first-type operating parameters. In the process of user switching and searching, the search is performed in the operating parameters whose historical call frequency is greater than or equal to the first frequency threshold, that is, the infrequently used operating parameters are eliminated, and the search is performed in the operating parameters that the user has frequently used before, so that the user can find the working parameters that need to be viewed or used faster, reducing the cumbersomeness of the switching operation.

[0085] Specifically, the third input includes a short press, wherein the short press includes a press with a press duration shorter than a first press duration threshold.

[0086] Furthermore, in the case where the display device displays the second content, the control method also includes receiving a third input from the user to the first button, switching the content of the display device to the seventh content, and the seventh content includes another second type of operating parameter of the electrical device. For example, in the case where the display device displays a second type of operating parameter, when the user makes a third input to the first button, in response to the third input, the display device adjusts the display content, and the displayed content becomes another second type of operating parameter, so that the user can switch and search between multiple second types of operating parameters. In the process of user switching and searching, the search is performed in the operating parameters whose historical call frequency is less than the first frequency threshold, that is, the commonly used operating parameters are eliminated, and the search is performed in the operating parameters that the user has not frequently used before, so that when the user needs to use a certain uncommon parameter, the user can find the working parameter that needs to be viewed or used faster, reducing the tediousness of the switching operation.

[0087] The switching between the first content and the third content can be performed multiple times, and the switching between the second content and the seventh content can also be performed multiple times, which is specifically determined by the number of short presses of the first button by the user, that is, the number of times the user performs the third input on the first button.

[0088] Figure 3 A flow chart of a control method of a human-machine interface device in one embodiment of the present invention is shown, wherein the control method comprises:

[0089] S302: When a display device of a human-machine interface device displays first content, the first content includes a first type of operating parameter of an electrical device;

[0090] S304: receiving a fourth input from the user on a second button of the human-machine interface device, and determining a parameter attribute of a first type of working parameter;

[0091] S306: When the parameter attribute is the first attribute, increase the value of the first type of working parameter according to a preset increase rate and a preset single increase value, and enable the display device to display the increase process.

[0092] In this embodiment, the control method further includes receiving a fourth input from a user to a second button of a human-machine interface device, and in response to the fourth input to the second button, determining a parameter attribute of a currently displayed first type of working parameter. Specifically, the second button is a button for adjusting a numerical value, wherein the second button is specifically used to increase a numerical value, and the fourth input is pressing the second button. The parameter attribute of the working parameter is a first attribute, and the first attribute specifically includes being unprotected or not requiring protection against human factors. The working parameter of this parameter attribute is a working parameter that can be adjusted independently by the user, and the corresponding parameter attribute of the working parameter also includes a second attribute, and the second attribute specifically includes being protected or requiring protection against human factors. The working parameter of this parameter attribute is more important to the operation of the electrical equipment, and under normal circumstances, certain adjustments are not allowed.

[0093] When it is determined that the parameter attribute is the first attribute, it means that the parameter can be adjusted, and the second button is a button for increasing the value, so the value of the first type of working parameter is increased according to the preset increase rate and the preset single increase value, and the display device displays the increase process. Specifically, the preset single increase value is one, and the preset increase rate is a dynamically changing value, which is related to the duration attribute of the fourth input and becomes faster as the duration increases.

[0094] For example, if the value of a first type of working parameter currently displayed is 50, and the duration attribute of the fourth input is 1 second, that is, the user presses the second button for 1 second, the preset increase rate is to increase by one preset single increase value per second, and the preset single increase value is 1, the display device will display 51. If the duration attribute of the fourth input is five seconds, that is, the user presses the second button for five seconds, it can be understood that the user has long pressed the second button, and the preset increase rate will reach two preset single increase values ​​per second at two seconds, three preset single increase values ​​per second at three seconds, four preset single increase values ​​per second at four seconds, and five preset single increase values ​​per second at five seconds. During the increase process, the display device displays 51 in the first second of pressing, 52 and 53 in sequence in the second second of pressing, 54, 55 and 56 in sequence in the third second of pressing, 57, 58, 59 and 60 in sequence in the fourth second of pressing, and 61, 62, 63, 64 and 65 in sequence in the fifth second of pressing, so as to clearly show the process of value adjustment to the user. There can be multiple specific relationships between the preset increase rate and the duration attribute of the fourth input, and the above description is only one of the cases, and the specific relationship can be set according to user requirements.

[0095] Specifically, the preset increase rate increases with time until the maximum increase rate value allowed is reached, and then the increase is performed according to the maximum increase rate value. In addition, if the operating parameter has reached its maximum allowed value, the increase is automatically stopped.

[0096] By making the value of the preset increase rate gradually increase with time, the user can more conveniently modify the working parameter value.

[0097] Specifically, when the display device of the human-machine interface device displays the second content, the control method further includes: receiving a fourth input of the user to the second button of the human-machine interface device, determining the parameter attribute of the second type of working parameter; when the parameter attribute is the first attribute, increasing the value of the second type of working parameter according to a preset increase rate and a preset single increase value, and causing the display device to display the increase process. That is, when the display device displays the second type of working parameter, the value of the second type of working parameter can also be adjusted by controlling the input of the second button.

[0098] Figure 4 A flow chart of a control method of a human-machine interface device in one embodiment of the present invention is shown, wherein the control method comprises:

[0099] S402: When a display device of a human-machine interface device displays first content, the first content includes a first type of operating parameter of an electrical device;

[0100] S404: receiving a fifth input from the user on a third button of the human-machine interface device, and determining a parameter attribute of a first type of working parameter;

[0101] S406: When the parameter attribute is the first attribute, the value of the first type of operating parameter is reduced according to a preset reduction rate and a preset single reduction value, and the display device displays the reduction process.

[0102] When the human-machine interface device is turned on, the human-machine interface device can display first content, and the first content includes a first type of operating parameter of the electrical device. Specifically, the first type of operating parameter includes multiple operating parameters whose historical call frequency is greater than or equal to a first frequency threshold.

[0103] The control method further includes receiving a fifth input from a user to a third button of a human-machine interface device, and in response to the fifth input to the third button, determining a parameter attribute of a currently displayed first type of working parameter. Specifically, the third button is a button for adjusting a numerical value, wherein the third button is specifically used to reduce the numerical value, and the fifth input is pressing the third button. The parameter attribute of the working parameter is a first attribute, and the first attribute specifically includes being unprotected or not requiring protection against human factors. The working parameter of this parameter attribute is a working parameter that can be adjusted independently by the user, and the corresponding parameter attribute of the working parameter also includes a second attribute, and the second attribute specifically includes being protected or requiring protection against human factors. The working parameter of this parameter attribute is more important to the operation of the electrical equipment, and under normal circumstances, certain adjustments are not allowed.

[0104] When it is determined that the parameter attribute is the first attribute, it means that the parameter can be adjusted, and the third button is a button for decreasing the value, so the value of the first type of working parameter is decreased according to the preset decrease rate and the preset single decrease value, and the display device displays the decrease process. Specifically, the preset single decrease value is one, and the preset decrease rate is a dynamically changing value, which is related to the duration attribute of the fifth input and becomes faster as the duration increases.

[0105] For example, if the value of a first type of working parameter currently displayed is 50, the duration attribute of the fifth input is one second, that is, the user presses the third button for one second, the preset reduction rate is to reduce by one preset single reduction value per second, and the preset single reduction value is one, the display device will display 49. If the duration attribute of the fifth input is five seconds, that is, the user presses the third button for five seconds, it can be understood that the user has long pressed the third button, then the preset reduction rate will reach two preset single reduction values ​​per second at two seconds, three preset single reduction values ​​per second at three seconds, four preset single reduction values ​​per second at four seconds, and five preset single reduction values ​​per second at five seconds. During the reduction process, the display device displays 49 in the first second of pressing, 48 and 47 in sequence in the second second of pressing, 46, 45 and 44 in sequence in the third second of pressing, 43, 42, 41 and 40 in sequence in the fourth second of pressing, and 39, 38, 37, 36 and 35 in sequence in the fifth second of pressing, so as to clearly show the user the process of value adjustment. There can be multiple specific relationships between the preset reduction rate and the duration attribute of the fifth input, and the above description is only one of the cases, and the specific situation can be set according to user requirements.

[0106] Specifically, the preset reduction rate increases with time until the maximum reduction rate value allowed is reached, and then the reduction is performed according to the maximum reduction rate value. In addition, if the operating parameter has reached its minimum allowed value, the reduction is automatically stopped.

[0107] By making the value of the preset reduction rate gradually decrease with the increase of time, the user can more conveniently modify the working parameter value.

[0108] Specifically, when the display device of the human-machine interface device displays the second content, the control method further includes: receiving a fifth input of the user to the third button of the human-machine interface device, determining the parameter attribute of the second type of working parameter; when the parameter attribute is the first attribute, reducing the value of the second type of working parameter according to a preset reduction rate and a preset single reduction value, and making the display device display the reduction process. That is, when the display device displays the second type of working parameter, the user controls the input of the third button so that the control device of the human-machine interface device responds accordingly, and can also adjust the value of the second type of working parameter.

[0109] Figure 5 A flow chart of a control method of a human-machine interface device in one embodiment of the present invention is shown, wherein the control method comprises:

[0110] S502: When a display device of a human-machine interface device displays first content, the first content includes a first type of operating parameter of an electrical device;

[0111] S504: When a problematic parameter is detected, switching the display content of the display device to a fourth content;

[0112] S506: receiving a sixth input on a second button of the human-machine interface device and a seventh input on a third button of the human-machine interface device from the user at the same time, and switching the content displayed by the display device to the first content.

[0113] In this embodiment, the electrical device will perform self-checks on multiple working parameters during operation. When a problematic parameter is detected during the self-check, the human-machine interface device in a state of continuously acquiring the problematic parameter will acquire the problematic parameter.

[0114] When a problem parameter is detected, the display content of the display device is switched to a fourth content, and the fourth content includes at least one alarm prompt message, so as to remind the user that a problem has occurred with the current electrical equipment and that repair and debugging is required.

[0115] When simultaneously receiving the fifth input from the user on the second button of the human-machine interface device and the seventh input from the user on the third button of the human-machine interface device, the control device of the human-machine interface device responds accordingly, deeming that the user is aware of the alarm prompt information and no longer needs to view the alarm prompt information, and switches the content displayed by the display device to the first content, and displays the first type of working parameters normally.

[0116] By setting the display of alarm prompt information, the risk of users ignoring problems with electrical equipment can be reduced, and the normal operation of electrical equipment can be better guaranteed. In addition, the alarm prompt information is eliminated only when the input control of the second button and the third button is received at the same time, and the normal first type of working parameter display is performed, which can avoid the situation where the alarm prompt information is eliminated due to accidental touch.

[0117] Specifically, when a problem parameter occurs, the display switching of the fourth content has the highest priority, that is, no matter what content is displayed at this time, the display content of the display device will be immediately switched to the fourth content, thereby improving the timeliness of knowing the problem and avoiding late processing of the electrical equipment and affecting the operation of the electrical equipment.

[0118] Furthermore, when there are multiple question parameters but only one alarm prompt information can be displayed, the fourth content includes the alarm prompt information corresponding to the question parameter with the most recent time. The user can switch to view different alarm prompt information by the fourth input of the second button and the fifth input of the third button.

[0119] Figure 6 A flow chart of a control method of a human-machine interface device in one embodiment of the present invention is shown, wherein the control method comprises:

[0120] S602: When a display device of a human-machine interface device displays first content, the first content includes a first type of operating parameter of an electrical device;

[0121] S604: receiving a third input from a user on a first button of the human-machine interface device, switching the content displayed by the display device to fifth content, where the fifth content includes display function parameters;

[0122] S606: receiving a fourth input from the user on a second button of the human-machine interface device, and starting a parked display mode;

[0123] S608: receiving a first input of a user on a first button, and switching the content displayed by the display device to a second content;

[0124] S610: Locking the content displayed by the display device to the second content.

[0125] In this embodiment, the control method further includes: receiving a third input from the user to the first button of the human-machine interface device, specifically, the third input is a short press of the first button. In the case of receiving the third input from the user to the first button of the human-machine interface device, the content displayed by the switching display device is the fifth content, and the fifth content specifically includes a display function parameter, and the display function parameter is used to adjust the display mode of the human-machine interface device. Specifically, the display mode includes a return display mode and a parking display mode. After the human-machine interface device is turned on, the display mode defaults to the return display mode, and receiving the fourth input from the user to the second button of the human-machine interface device will correspondingly switch from the return display mode to the parking display mode, that is, turn on the parking display mode.

[0126] Afterwards, if the user inputs the first button, the content displayed on the switching display device is the second content, the second content includes a second type of operating parameter of the electrical device, and the content displayed on the locking display device is the second content, that is, the human-machine interface device is kept to display the second content switched by the user, and will not jump back to display the first content when no operation instruction from the user is received, so as to facilitate the use of the user.

[0127] It is understandable that in this application, various working parameters and display function parameters and other different function type parameters are integrated and sorted together. Through multiple third inputs to the first button, that is, multiple short presses of the first button, the display device of the human-machine interface device can display different first-type working parameters in sequence, and after a certain number of switchings and displaying a certain number of first-type working parameters, if the third input to the first button is received again, the content displayed by the display device will be switched to the fifth content, and the fifth content includes the display function parameters.

[0128] Figure 7 A flow chart of a control method of a human-machine interface device in one embodiment of the present invention is shown, wherein the control method comprises:

[0129] S702: When a display device of a human-machine interface device displays first content, the first content includes a first type of operating parameter of an electrical device;

[0130] S704: receiving a third input from a user on a first button of the human-machine interface device, switching the content displayed by the display device to fifth content, where the fifth content includes display function parameters;

[0131] S706: receiving a fourth input from the user on a second button of the human-machine interface device, and starting a parked display mode;

[0132] S708: receiving a first input of a user on a first button, and switching the content displayed by the display device to a second content;

[0133] S710: enabling the display device to display the parameter name of the second type of operating parameter;

[0134] S712: After the display duration reaches the first duration, display the parameter value of the second type of working parameter;

[0135] S714: After the display duration reaches a second duration, the parameter name of the second type of working parameter is displayed.

[0136] In this embodiment, the display content of the locking display device specifically includes: first, the display device displays the parameter name of the second type of working parameter, so that the user can know which parameter is currently displayed, and after the display time of the parameter value of the second type of working parameter reaches the first time, the parameter value of the second type of working parameter is displayed, so that the user can know the parameter value of the currently displayed parameter. After the display time of the parameter value of the second type of working parameter reaches the second time, the display will return to the parameter name of the second type of working parameter, and the above process can be repeated multiple times for the convenience of user viewing.

[0137] Figure 8 A flow chart of a control method of a human-machine interface device in one embodiment of the present invention is shown, wherein the control method comprises:

[0138] S802: When a display device of a human-machine interface device displays first content, the first content includes a first type of operating parameter of an electrical device;

[0139] S804: receiving a first input from a user on a first button of a human-machine interface device, and switching the content displayed by the display device to a second content;

[0140] S806: When the first input or the second input is not received within the third time period, switch the display content of the display device to the first content.

[0141] In this embodiment, after the human-machine interface device is turned on, the display mode defaults to the return display mode. If the first input or the second input is not received within the third time period, it means that the user does not want to switch the operation, and the control device of the human-machine interface device will control the display device accordingly, switch the display content of the display device to the first content, and realize the reset of the display content. Specifically, the first content specifically includes: a first type of working parameter that meets the priority display requirement or a first type of working parameter that meets the user setting requirement.

[0142] Furthermore, when the display device of the human-machine interface device displays the first content, the first content includes a first type of operating parameter of the electrical device, and the control method also includes: receiving a third input from the user to the first button of the human-machine interface device, switching the display content of the display device to a sixth content, the sixth content including an anti-human error function parameter; receiving a fifth input from the user to the third button of the human-machine interface device, turning off the anti-human error function of the human-machine interface device.

[0143] During the operation of the human-machine interface device, the anti-error function is enabled by default, and the value of the anti-error function parameter is 1. When the anti-error function is enabled, some commonly used working parameters with the second attribute, that is, protected working parameters, are not allowed to be modified, or some uncommon working parameters with the second attribute, that is, protected working parameters, are not displayed, so that the amount of working parameters that users view normally is reduced, which is convenient for users to quickly find the working parameters they want to view.

[0144] When receiving the third input of the user to the first button, the display content of the display device is switched to the sixth content, and the sixth content includes an anti-error function parameter; when receiving the fifth input of the user to the third button, the anti-error function of the human-machine interface device is turned off. Specifically, when receiving the fifth input to the third button, because the third button is a button for reducing the parameter, the value of the anti-error function parameter, which is originally 1, is modified to zero, thereby turning off the anti-error function, turning off the protection of the commonly used working parameters with the parameter attribute of the second attribute, and hiding the display of the uncommon working parameters with the parameter attribute of the second attribute, thereby meeting the various needs of the user.

[0145] In one embodiment of the present invention, the execution subject of the control method of the human-machine interface device may be a control device of the human-machine interface device. In order to more clearly illustrate the control method of the human-machine interface device proposed in the present invention, the execution subject of the control method of the human-machine interface device is exemplified as a control device of the human-machine interface device in the following embodiment.

[0146] First, the control device of the human-machine interface device controls the human-machine interface device to obtain multiple working parameters of the electrical equipment, and analyzes and compares the historical call frequency of each working parameter, and determines that the parameters greater than or equal to the first frequency threshold are of the first type, that is, the user's commonly used parameters all belong to the first type. The parameters less than the first frequency threshold are of the second type, that is, the parameters that the user does not often use belong to the second type. Among them, the working parameters that belong to the first type and the parameter attribute is the first attribute, that is, unprotected working parameters such as A1, A2, etc. The working parameters that belong to the first type and the parameter attribute is the second attribute, that is, protected working parameters such as A01, A02, etc. The working parameters that belong to the second type and the parameter attribute is the first attribute, that is, unprotected working parameters such as B1, B2, etc. The working parameters that belong to the second type and the parameter attribute is the second attribute, that is, protected working parameters such as B01, B02, etc. X1, etc., which are problem parameters.

[0147] The above parameters are classified and a corresponding working parameter classification table is prepared (as shown in Table 1 below).

[0148] Table 1 Classification of working parameters

[0149]

[0150] After the working parameters are classified, a working parameter classification table is prepared, and the control device of the human-machine interface device stores the working parameter classification table. After the human-machine interface device is turned on, the control device of the human-machine interface device executes the control method of the human-machine interface device accordingly. Specifically, Fig. 9 A flow chart of a control method of a human-machine interface device in one embodiment of the present invention is shown, wherein the control method comprises:

[0151] S902: Displaying a first type of operating parameter A1 on a display device of a human-machine interface device;

[0152] S904: receiving a third input of the user to the first button, and switching the display device to display the first type of operating parameters A2;

[0153] S906: receiving a third input of the user to the first button, and switching the display device to display the first type of working parameters A01:

[0154] S908: receiving a third input of the user to the first button, and switching the display device to display the first type of working parameter A02;

[0155] S910: receiving a first input from a user on a first button of a human-machine interface device, and switching the content displayed by the display device to a second type of operating parameter B1;

[0156] S912: receiving a third input of the user to the first button, and switching the content displayed on the display device to the second type of working parameter B2;

[0157] S914: receiving a third input of the user on the first button, and switching the content displayed by the display device to a fifth content;

[0158] S916: receiving a fourth input from the user on a second button of the human-machine interface device, and starting a parked display mode;

[0159] S918: receiving a third input of the user on the first button, and switching the content displayed by the display device to a sixth content;

[0160] S920: receiving a fifth input of the user on the third button, and disabling the anti-error function of the human-machine interface device;

[0161] S922: receiving a third input of the user to the first button, and switching the content displayed on the display device to the second type of working parameter B01.

[0162] During the process of the control device of the human-machine interface device executing the control method of the human-machine interface device, when the device is turned on, the first type of operating parameter A1 is displayed on the display device of the human-machine interface device. Thereafter, if a third input of the user to the first button is received, in response to the third input, the content displayed on the display device is switched to the first type of operating parameter A2, so as to display another commonly used operating parameter to the user.

[0163] Thereafter, a third input from the user to the first button is received. In response to the third input, the content displayed by the display device is switched to the first type of working parameter A01, so as to display another commonly used working parameter to the user. A01 is a working parameter that can only be viewed by the protected user at ordinary times.

[0164] Thereafter, a third input from the user to the first button is received. In response to the third input, the content displayed by the display device is switched to the first type of working parameter A02, so as to display another commonly used working parameter to the user. A02 is a working parameter that can only be viewed by the protected user at ordinary times.

[0165] Thereafter, a first input of the user to a first button of the human-machine interface device is received, and the content displayed by the display device is switched to the second type of operating parameter B1, so as to display an uncommon operating parameter to the user.

[0166] Thereafter, a third input of the user to the first button is received, and in response to the third input, the content displayed by the display device is switched to the second type of operating parameter B2, so as to display another infrequently used operating parameter to the user.

[0167] Thereafter, in this display situation, receiving a third input from the user to the first button, the display content of the display device can be switched to a fifth content, where the fifth content includes a display function parameter.

[0168] By receiving the fourth input of the user to the second button, or the fifth input of the user to the third button, and modifying the value of the display function parameter, switching between the return display mode and the stop display mode can be achieved.

[0169] Then, a third input of the user to the first button is received, and the display content of the display device is switched to the sixth content, where the sixth content includes a parameter of the anti-mistake function.

[0170] Receive the fifth input of the user to the third button, modify the value of the anti-error function parameter to zero, and turn off

[0171] The anti-error function of the human-machine interface device is turned off. Because the anti-error function is turned off, the protection of the commonly used working parameters with the 5 parameter attributes as the second attribute is turned off, and the hidden display of the uncommon working parameters with the parameter attributes as the second attribute is turned off.

[0172] Thereafter, a third input from the user to the first button is received. In response to the third input, the content displayed by the display device is switched to the second type of working parameter B01, thereby showing the user an infrequently used working parameter that was previously hidden and whose parameter attribute was the second attribute.

[0173] 0Thereafter, a third input of the user to the first button is received. In response to the third input, the content displayed by the display device is switched to the second type of working parameter B02, so as to display another working parameter which is not frequently used and was previously hidden and has the second attribute as the parameter attribute.

[0174] In one embodiment of the present invention, a control device for a human-machine interface device is provided, comprising a processor, a memory, and a program or instruction stored in the memory and running on the processor, wherein when the program or instruction is executed by the processor, the steps of the control method for the human-machine interface device in any of the above embodiments are implemented.

[0175] In this embodiment, the control device of the human-machine interface device proposed by the present invention, when the program or instruction is executed by the processor, implements the control method of the human-machine interface device in any of the above embodiments.

[0176] The method has all the beneficial effects of the method for controlling a human-machine interface device in any of the above embodiments, which will not be described in detail here.

[0177] In one embodiment of the present invention, Fig.10As shown, a human-machine interface device 950 is proposed, including: a body 952, used to connect with an electrical device, the body 952 can obtain various working parameters of the electrical device; a display tube 954, arranged on the body 952, used to display the working parameters;
