Description

Technical Field

[0001] The present invention relates to the field of intelligent industrial control technology, and in particular to a mode switching method and a serial port screen. Background Art

[0002] In the field of modern industrial control, serial port screens, as a common human-computer interaction device, are widely used in various types of automation equipment and instruments.

[0003] However, traditional serial port displays present several issues with control state management and mode switching, such as cumbersome operation and inconvenient state switching, resulting in low user efficiency and a high risk of operational errors. Specifically, user operation is cumbersome, requiring multiple taps on the screen to switch between modes or adjust control states, leading to low efficiency. Furthermore, control state management and storage are inflexible, requiring users to repeatedly set parameters, increasing operational complexity and the risk of error. Therefore, existing serial port display solutions have at least the following disadvantages: Traditional serial port displays have weak logic, require enumeration, require large Flash memory, and are costly; Android / Linux displays have high costs; and users may need to repeatedly enter or select parameter values ​​when setting parameters in existing serial port display technologies, which is cumbersome. This tedious parameter setting process can increase the user's operational burden and the potential for error. Given the cumbersome operation of current serial port displays, which require repeated input or selection of parameter values ​​when switching between modes, further research on mode switching methods is necessary.

[0045] Figure 2 FIG. 4 is a schematic diagram of a mode switching device according to another embodiment of the present invention. DETAILED DESCRIPTION

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0047] See Figure 1 , a mode switching method according to an embodiment of the present invention comprises the following steps:

[0048] Step 11: Obtain control parameters based on Lua programming technology.

[0049] In the embodiment of the present invention, the control parameters include multiple values ​​such as Parameter1, Parameter2 and Parameter3.

[0050] Step 12: Determine the mode to be switched corresponding to the control parameter.

[0051] In this step, the mode to be switched corresponds to the data in the Schedule table in the Select control. Step 12 may specifically include:

[0052] The waiting mode is selected first according to the value of Parameter1;

[0053] When the value of Parameter1 is 0, the waiting mode is selected according to the value of Parameter2;

[0054] When the values ​​of Parameter1 and Parameter2 are both 0, the waiting mode is selected according to the value of Parameter3.

[0055] Step 13. According to the mode to be switched, use the Convert function to encapsulate the control parameters in the corresponding state variables of the Select control. The state variables are used to update the Select control. The Select control includes two or more state address groups with different priority levels. Each state address group includes two or more state address blocks with different priority levels. The state variables are stored in the state address blocks, and the mode selection corresponds one-to-one to the state address block.

[0056] In this embodiment of the present invention, step 13 may specifically include:

[0057] When the value of Parameter1 is not 0, the control parameter is encapsulated in State1 in the Schedule table; that is, Parameter1 corresponds to the state address group with a high priority;

[0058] When the value of Parameter1 is 0 and the value of Parameter2 is not 0, the control parameters are encapsulated in State2 in the Schedule table; Parameter2 corresponds to the state address group with medium priority;

[0059] When the values ​​of Parameter1 and Parameter2 are both 0, and the value of Parameter3 is not 0, the control parameters are encapsulated in State3 in the Schedule table; Parameter3 corresponds to the state address group with a low priority.

[0060] Step 14: Store the state variable into the corresponding Flash address.

[0061] In the embodiment of the present invention, after step 14, the method further includes:

[0062] The assignment displays the result of storing the state variable in the corresponding Flash address. That is, the data in the Select table will be stored in the corresponding Flash address, and the assignment display will be displayed when the data is read.

[0063] Step 15: Switch the mode according to the mode to be switched and the state variable and display the visualization parameters in the updated Flash address.

[0064] In this step, by switching the corresponding mode, the data stored in the flash can be displayed, or the data can be stored in the corresponding flash.

[0065] The existing serial port screen generally controls the status switching of the serial port screen through the upper computer development software or the single-chip microcomputer MCU. However, after downloading the project through the development software, it is difficult to affect the controls of the serial port screen, and the control status cannot be adjusted in real time. And by sending serial port instructions to set the serial port screen status through the single-chip microcomputer MCU, it is impossible to switch the status of all controls at the same time. The embodiment of the present invention obtains the control parameters at one time through Lua programming technology, completes the corresponding judgment of the mode to be cut and the encapsulation of the state variables and the update in Flash, and finally switches the mode and displays the corresponding Flash, which solves the problem that the current serial port screen needs to repeatedly enter or select parameter values ​​when switching modes, resulting in cumbersome operations.

[0066] The embodiment of the present invention uses a Lua script control operating system, so users can implement complex logical operations, automatically sort according to the rules, reduce the logical operations of the user's mainboard, and improve the operating efficiency and user experience of the serial screen. The control operating system realizes flexible management of the control state and rapid switching of modes through functions such as initialization function, timing callback function and timer timeout callback function, so that users can easily operate and control the serial screen device. The advantage of this technology is that it simplifies the serial screen operation process and enhances user interactivity. The expected effect is to improve system stability, reduce operating errors, and bring a more intelligent and convenient operating experience to the field of industrial control. In the future, the control operating system is expected to be widely used in industrial automation, intelligent instrumentation and other fields, and play an important role in improving industrial production efficiency and quality.

Each state address group includes two or more state address blocks with different priority levels. The state variables are stored in the state address blocks.
