Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of liquid crystal display screen multi-interface display, and more particularly to a stack-based on-site operation panel multi-interface switching implementation method and an on-site operation panel. BACKGROUND

[0002] Multiple interface displays can be set on a human-computer interaction interface, and different operation functions are placed on different interfaces according to function units and the like. When needed, interface switching is performed through multi-interface switching technology. Multi-interface switching methods can be implemented based on different technologies. Currently, common methods include page navigation, graphical user interface library and the like.

[0003] An application No. CN201910785521.5 discloses an interface switching method and device. When a user trigger operation for a communication application is detected, an entry selection interface of the communication application is started, an entry option of a communication interface related to a user history operation is displayed in a first area of the entry selection interface, an entry option of a group management function interface related to the user history operation is displayed in a second area of the entry selection interface, and according to a user selection operation for the displayed entry option, the interface corresponding to the selected entry option is switched to. An application No. CN202010177866.5 discloses an interface switching method, device and electronic equipment. When a user interface switching operation is detected, at least two interfaces of at least one target application program are acquired, the acquired interfaces are displayed in a first preset area, and according to a user selection of a target interface identifier in the first preset area, the interface corresponding to the target interface identifier is displayed on the screen, so that the switching between interfaces in an application program or between application programs is facilitated, and the user experience is improved. An application No. CN202311828454.3 discloses an interface switching method, device and electronic equipment. A switching instruction for a target interface is acquired, a target parameter is determined based on the switching instruction, a first image element in the target interface is adjusted to a first style associated with the target parameter, a second image element in the target interface is adjusted to a second style associated with the target parameter, and the first style is different from the second style. An application No. CN202211203511.4 discloses an interface display method and electronic equipment. When the interface displayed by the electronic equipment is a split-screen interface, the user can trigger the electronic equipment to switch the application displayed in the split-screen interface through operation, without the user needing to reopen a desktop or a multi-task interface to switch one or more applications displayed in the split-screen interface, thereby simplifying the user operation and improving the user experience.

[0004] However, these methods have some disadvantages, for example: for complex systems, users can be difficult to understand the structure of the entire system, increasing the cognitive burden of users, if the number of pages is large, users can be confused, do not know how to switch from one interface to another interface; and in resource-limited embedded systems, frequent interface switching can consume too much processing power and memory.

[0005] Therefore, how to provide a simple field operation panel multi-interface switching implementation method is a technical problem that those skilled in the art need to solve. SUMMARY

[0022] From the position i, the loop of data[i]=data[i+1] is executed, the value of i is increased by 1 each time, and the loop is ended until the value of i is equal to the value of len, that is, the interface number of the next stack space position is replaced with the interface number of the original stack space position, finally the repeated interface number is moved from the original stack space position to the top position, and the total number of interface numbers in the stack is not changed, that is, the value of len is not changed.

[0023] If there is no repeated interface number, the value of top+1 is assigned to len.

[0039] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments only constitute a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the protection scope of the present application.

[0040] The embodiment of the present application discloses a stack-based multi-interface switching implementation method for an on-site operation panel, as shown in the accompanying drawings, comprising the following steps: Figure 1

[0041] S1, numbering display functions corresponding to each interface of the on-site operation panel;

[0042] S2, constructing an empty stack and storing the numbers corresponding to the interface display functions in the empty stack;

[0043] S3, when entering a target interface, performing a stack operation on the number corresponding to the display function of the target interface, and judging and processing whether the number exists in the stack;

[0044] S4, placing the number corresponding to the display function of the target interface at the top of the stack, calling the display function corresponding to the interface number at the top of the stack, and completing the interface switching.

[0045] Further, in S1, the display functions corresponding to each interface of the on-site operation panel are numbered, specifically:

[0046] One interface of the on-site operation panel corresponds to one display function, n identifiers are used to represent each interface, and n identifiers are defined as n constants by using macro definition, obtaining n interface numbers 1-n.

[0047] Further, in S2, when constructing an empty stack, the top position of the stack is defined as top, the space size of the stack is defined as stacksize, the stack data element array is defined as data, and the current stack element quantity is defined as len.

[0048] In order to accurately switch and control each interface of the on-site operation panel, the embodiment stores each interface number in the stack as needed and manages it, and the stack operations involved include six kinds:

[0049] (1) creating an empty stack

[0050] Create a stack PageStack based on the stack structure, and set the initial value of top to -1; the initial value of stacksize to a value that can satisfy the number of interfaces as much as possible, for example, 100; the initial value of len to 0; the stack is used to store the interface numbers corresponding to the interfaces that need to be displayed on the liquid crystal screen.

[0051] (2) judging whether the current stack PageStack is an empty stack

[0052] Judge whether the top value of the stack is equal to -1 or the len value of the stack is equal to 0, if it is an empty stack, it indicates that there is no interface display at present, return 1; otherwise, return 0.

[0053] ​(3) Get the top element of the stack PageStack

[0054] First, it is necessary to determine whether the PageStack is empty. If not, the top value is taken as the index of the array data to get the top element, that is, the number of the interface currently displayed on the liquid crystal screen. If it is empty, 0 is returned.

[0055] (4) Insert a new element into the stack PageStack

[0056] First, compare the len of the stack with the stacksize. If the len is less than the stacksize, the stack is not full, that is, there is space in the stack for new elements to be stored. Set top = top + 1 and assign the new element to data[top], that is, add the new interface number to the top of the stack PageStack, and set the current len value to top + 1. At this time, the liquid crystal screen will update the interface in real time according to the interface number at the top of the stack PageStack, and return 1. If the len is equal to the stacksize, the stack is full, and 0 is returned.

[0057] (5) Delete the top element of the stack PageStack

[0058] First, determine whether the PageStack is empty. If not, set a temporary variable e to store the value of the element to be deleted. Set top = top - 1 and len = top + 1, and finally return e, so that the interface number at the top of the original stack is overwritten by the previous interface number, achieving interface rollback. If it is empty, 0 is returned.

[0059] (6) Determine whether the current stack PageStack is full

[0060] First, determine whether the len value of the stack is equal to the stacksize value of the stack. If they are equal, the stack is full, indicating that the interface switching has failed, and 0 is returned. Otherwise, 1 is returned.

[0061] In this embodiment, as shown in Figure 2 , Figure 3 In S3, when entering a target interface, the number corresponding to the display function of the target interface is stacked, and the interface number stacking includes the following steps:

[0062] S301, the interface number stacking module starts, and S302 is executed;

[0063] S302, determine whether the current number of stack elements len is less than the space size stacksize of the stack. If yes, execute S304, otherwise execute S303;

[0064] S303, if the stack-in fails, return 0, and execute S306;

[0065] S304, stack the number corresponding to the display function of the target interface, and make the number be at the top of the stack, and add 1 to the value of the top position top, and use top as an index value to store the target interface number in data, that is, insert the target interface number at the top position, and execute S305;

[0066] S305, if the stack-in succeeds, return 1, and execute S306;

[0067] S306, exit the module.

[0068] The frequent multi-interface switching operation causes a large number of repeated elements to be stored in the stack, thereby causing the stack to be full. Therefore, the embodiment provides a new stack-in operation, which judges and processes whether there is a repeated interface number in the stack, as shown in Figure 4 、 Figure 5 and specifically includes the following steps:

[0069] S311, the module of judging and processing whether there is a repeated interface number in the stack starts, and executes S312;

[0070] S312, define a variable pos to store the position of the original top element, that is, assign the value of top to pos, and execute S313;

[0071] S313, traverse and find all interface numbers in the stack, and execute S314;

[0072] S314, judge whether there is an interface number value a in the stack that is the same as the interface number value newly stacked at this time, if yes, execute S316, otherwise execute S315;

[0073] S315, assign the value of top+1 to len, and execute S317;

[0074] S316, define the index of the array of the interface number value a in the stack as i, and set the value of the variable pos as i; start from the position i, and execute data[i]=data[i+1] in a loop, the value of i is increased by 1 each time the loop is executed, and the loop ends until the value of i is equal to the value of len, that is, the interface number of the next stack space position is used to replace the interface number of the original stack space position in turn, finally the repeated interface number is moved from the original stack space position to the top position, and the total number of interface numbers in the stack does not change, that is, the value of len is not changed, and execute S317;

[0075] S317, exit the module.

[0076] Further, as shown in Figure 6 , the embodiment provides a multi-interface real-time display method, which includes the following steps:

[0077] S401, the interface real-time display module starts, and S402 is executed;

[0078] S402, the interface switching function show_page obtains the interface number located at the top of the stack at the moment, and the corresponding interface display function is called according to the obtained interface number, and S403 is executed;

[0079] S403, the interface switching function show_page is called in the main function, and S404 is executed;

[0080] S404, the module is exited.

[0081] The above multi-interface switching implementation method needs to be realized through a field operation panel, as shown in the accompanying drawings, which comprises an embedded microprocessor, a power module, a liquid crystal display module, a key module and a communication module. Figure 7

[0082] The power module is connected with the liquid crystal display module and the embedded microprocessor respectively.

[0083] The embedded microprocessor is connected with the liquid crystal display module, the key module and the communication module through a liquid crystal display driving circuit, a GPIO port and a communication port respectively.

[0084] Further, the embedded microprocessor is internally provided with an empty stack, as shown in the accompanying drawings, the stack structure body of the empty stack comprises a top position top, a stack space size stacksize, a stack data element array data and a current stack element quantity len. Figure 8

[0085] In summary, the embodiment uses a simple method, combines the stack data structure, uses the last-in first-out feature of the stack, the interface switching behavior is predictable, the user can easily know how to "back up" to the previous interface and how to "enter" the target interface, the multi-interface switching is realized, and the program complexity is reduced.
