Those skilled in the art will appreciate that the terminal structure shown in fig. 1 does not constitute a limitation of the terminal device and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
As shown in fig. 1, a memory 1005, which is a kind of computer-readable storage medium, may include therein an operating system, a network communication module, a user interface module, and a display program of an LCD.
In the terminal shown in fig. 1, the network interface 1004 is mainly used for connecting to a backend server and performing data communication with the backend server; the user interface 1003 is mainly used for connecting a client (user side) and performing data communication with the client; and the processor 1001 may be configured to call up a display program of the LCD stored in the memory 1005 and perform the following operations:
acquiring word stock information in a human-computer interface;
if the word stock information is inconsistent with the target word stock information, downloading the target word stock information into the human-computer interface, wherein the target word stock information is the word stock information in the control system;
sending display information to the human-computer interface so that the human-computer interface obtains a character lattice corresponding to the display information from the target word stock information and displays the character lattice;
and receiving key information sent by the human-computer interface, executing key operation corresponding to the key information to obtain result information of key processing, and sending the result information to the human-computer interface.
Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of a display method of an LCD according to the present application, the display method of the LCD includes the following steps:
step S10, acquiring word stock information in the human-computer interface;
because the traditional LCD display generally stores the interface and the word stock in the HMI module, if a customer needs to customize a control system, the HMI and the control system need to be modified simultaneously, thereby improving the complexity of a software algorithm and increasing the difficulty of modifying software codes.
The control system and the HMI human-computer interface are both stored with a word stock consisting of information such as words, letters, numbers, punctuation marks, special characters and the like; the control system can automatically generate version numbers, time stamps and other information of the word stock when the executable file is generated by recompiling every time; and after the control system and the HMI restore communication, reading word stock information in the HMI by the control system, wherein the word stock information comprises word stock version information, time stamp information generated by a word stock, character number and other information.
Optionally, when the word stock needs to be updated, modified, and the like, the operation is directly performed at the control system end, for example, when the word stock needs to be updated, the control system determines the current version information of the word stock first, and analyzes the configuration file; according to the updating requirement, the original configuration file is modified, such as adding, deleting or changing characters, so as to generate a new configuration file; updating the configuration file in the font library software version through a configuration file updating module, namely replacing the original configuration file with the new configuration file; further, by operating a word stock updating command, the software automatically analyzes the new configuration file, so that the word stock is automatically updated, and a new word stock version is generated. By carrying out operations such as updating and modifying of the word stock at the control system end, the method facilitates software maintenance, simplifies customization and modification, and reduces the codes of a human-computer interface, thereby reducing the stock.
Further, referring to fig. 4, the step of acquiring the word stock information in the human-computer interface includes:
step S11, when the computer is started to run, sending an acquisition instruction of the word stock information to the human-computer interface;
and step S12, acquiring the word stock information in the human-computer interface according to the acquisition instruction.
The method comprises the steps that a control system sends an acquisition instruction of word stock information to an HMI (human machine interface) every time when the control system is powered on and operated, the HMI analyzes the acquisition instruction after receiving the acquisition instruction sent by the control system, further judges the word stock information required to be acquired by the acquisition instruction, such as word stock version information of a word stock, timestamp information generated by the word stock, the number of characters and the like, and returns the currently acquired word stock information to the control system.
Step S20, if the word stock information is inconsistent with the target word stock information, downloading the target word stock information into the human-computer interface, wherein the target word stock information is the word stock information in the control system;
when the word stock information in the control system is inconsistent with the word stock information in the HMI human-computer interface, the word stock information in the control system is not matched with the word stock information in the HMI human-computer interface; at the moment, the control system automatically downloads the word stock of the new version into the HMI human-machine interface so as to replace the word stock of the old version in the HMI human-machine interface. Optionally, when it is determined that the word stock information in the control system is inconsistent with the word stock information in the HMI human-machine interface, acquiring character information of an updated part in the new version word stock, and replacing the character information of the updated part with corresponding character information in the old version.
When the word library information corresponding to the control system is inconsistent with the word library information corresponding to the HMI human-computer interface, the word library information of the control system is directly downloaded to the HMI human-computer interface, so that the coding and the storage of the HMI human-computer interface are reduced, and the generation is convenient; meanwhile, the word stock information is downloaded during use, and the plug-and-play of the HMI man-machine interface is realized.
Further, referring to fig. 5, before the step of determining that the word stock information is inconsistent with the target word stock information, the method includes:
step S21, acquiring version information and timestamp information of the word stock in the human-computer interface;
step S22, judging whether the version information of the word stock in the human-computer interface is matched with the version information of the word stock in the target word stock and whether the timestamp information of the word stock in the human-computer interface is matched with the timestamp information of the word stock in the target word stock.
When the control system receives word stock information returned by the HMI, reading version information and timestamp information of a word stock in the HMI; the version information comprises version number, modification record, record label and other information, and the timestamp information is time node information of font updating. And further judging whether the version information of the word stock in the HMI human-computer interface is matched with the version information of the word stock in the target word stock and whether the timestamp information of the word stock in the HMI human-computer interface is matched with the timestamp information of the word stock in the target word stock. If the word stock information in the HMI is matched with the word stock information in the control system, the word stock information in the HMI is determined to be consistent, namely the word stock in the HMI is the latest version, and the control system does not need to push the word stock information to the HMI again. And if any item is not matched, determining that the word stock information in the HMI human-computer interface is inconsistent with the word stock information in the control system.
Step S30, sending display information to the human-computer interface, so that the human-computer interface obtains a character lattice corresponding to the display information in the target word stock information and displays the character lattice;
when characters need to be displayed, the control system pushes full-screen display information to the HMI (human machine interface), specifically, the control system generates a message of the full-screen display information, and when the information of the message meets the pushing condition, an http (hyper text transport protocol) pushing message is sent to the HMI human machine interface; determining whether an http feedback message sent by an HMI (human machine interface) is received, and if the feedback message is received, indicating that message pushing of full-screen display information is successful; if the feedback message is not received, the message of the full-screen display information is not pushed successfully, and the message of the full-screen display information is pushed to the HMI. After receiving a message of full-screen display information, the HMI acquires the full-screen display information in the message, further acquires character codes in the full-screen display information, searches a corresponding character lattice in a word stock according to the character codes, and displays the character lattice; the character lattice is a character shape formed by a group of points, the lattice of each character can be represented by several bytes according to the size, and the lattice number is 5 × 7 or 7 × 9.
Further, referring to fig. 6, the step of sending display information to the human-computer interface to enable the human-computer interface to obtain a character lattice corresponding to the display information in the target word stock information, and displaying the character lattice includes:
step S31, sending the character code of the display information to the human-machine interface, so that the human-machine interface obtains the character lattice corresponding to the character code in the target font information, obtains lattice coordinate information in the character lattice, and displays the character on the coordinate position corresponding to the lattice coordinate information.
And the control system sends the character codes of the full-screen display information to an HMI (human machine interface) through a communication channel, wherein the character codes comprise a UNICODE code, a GB2312 code and the like. And after receiving the character codes of the full-screen display information, the HMI acquires the character dot matrix corresponding to the character codes from the character library, further acquires dot matrix coordinate information in the character dot matrix, and displays the characters on the coordinate positions corresponding to the dot matrix coordinate information. For example: taking reading and displaying a character lattice of a Chinese character as an example, the HMI human-machine interface obtains GB2312 codes according to the Chinese character, calculates the location and code bits of the Chinese character in a lattice word stock through the GB2312 codes, calculates the offset in the lattice word stock through the location and code bits, obtains 32 pixel storage bytes of the Chinese character based on the offset, analyzes the pixel bytes to obtain lattice coordinate information, and displays information bits at corresponding coordinates.
And step S40, receiving the key information sent by the human-computer interface, executing the key operation corresponding to the key information to obtain the result information of key processing, and sending the result information to the human-computer interface.
After the control system sends an http message for pushing full-screen display information to the HMI (human machine interface), the HMI sends key information back to the control system when responding to the message; the HMI human-computer interface is provided with a plurality of keys, the keys can be virtual keys or entity keys, and for the entity keys, the control system can detect whether the entity keys are triggered according to the voltage or current when the keys are pressed; for virtual keys, the control system may use corresponding software to detect whether a virtual key is triggered. When receiving key information returned by the HMI, the control system acquires key codes corresponding to the key information, and further determines key operations corresponding to the keys by the key codes, such as modifying display parameters, switching page display and the like; and executing key operation to obtain result information of key processing, and sending the result information to the HMI (human machine interface), wherein the result information comprises information on whether the key operation is finished or not, information on time spent on responding to the key information and the like.
After the HMI receives the result information, if the control system is determined to respond to the key information according to the result information, the content corresponding to the result information is displayed, for example, if the key operation is to modify the display parameters, the HMI displays the content after modifying the display parameters; and if the control system does not respond to the key information according to the result information, the key information is sent to the control system again.
In the embodiment, when the word stock information in the human-computer interface is acquired, whether the word stock information is consistent with the target word stock information is judged, if not, the target word stock information is downloaded to the human-computer interface, and the target word stock information is the word stock information in the control system; sending display information to the human-computer interface so that the human-computer interface obtains a character lattice corresponding to the display information from the target word stock information and displays the character lattice; and receiving key information sent by the human-computer interface, executing key operation corresponding to the key information to obtain result information of key processing, and sending the result information to the human-computer interface. The interface, the word stock, the keys and the like are processed at the control system end, and the HMI only realizes the display function, so that HMI software and the control system do not need to be modified simultaneously when the control system is customized, and the effects of reducing the complexity of a software algorithm, facilitating software maintenance and simplifying the customization and modification are achieved.
Further, referring to fig. 3, a second embodiment of the display method of the LCD of the present application is proposed.
The second embodiment of the display method of the LCD is different from the first embodiment of the display method of the LCD in that the step of executing the key operation corresponding to the key information to obtain the result information of the key processing includes:
step S41, if the key operation corresponding to the key information is the modification operation of the display parameters, determining the parameter value to be modified in the current display parameters according to the key information;
and step S42, modifying the parameter value to be modified into a set value to obtain modified display parameter information.
Parameters on the HMI are mainly used for display parameter modification, page switching, display format modification and the like, if the key operation corresponding to the key information received by the control system is the modification operation of the display parameters, the parameter value to be modified in the current display parameters is determined according to the key information, and the parameter value to be modified is further modified into a set value to obtain the modified display parameter information; the display parameters comprise color parameters, character size parameters, display window size parameters, resolution parameters and the like, and the set values are input parameter values. For example: if the key operation corresponding to the key information is the modification of the character size parameter, determining the character to be modified in the currently displayed characters, if the currently displayed character has the display of an LCD (liquid crystal display), and if the character to be modified is the display, acquiring the character size of the displayed character, such as the number four; and further acquiring the character size of the input character, and if the character size of the input character is the second number, changing the character size of the display from the fourth number to the second number. Optionally, the color of the character to be modified may also be set simultaneously, specifically, the original color of the character to be modified, such as black, is obtained, and further, the input color information, such as red, is obtained from the key information; and modifying the color of the character to be modified from black to red. And the control system sends the modified parameter information to the HMI human-machine interface so that the HMI human-machine interface displays the modified character information.
Further, referring to fig. 7, the step of executing the key operation corresponding to the key information to obtain result information of key processing further includes:
step S43, if the key operation corresponding to the key information is the switching operation of the display content, determining the display content to be switched according to the key information;
and step S44, switching the display content to be switched into the set display content to obtain the switched display content.
When the control system determines that the key operation corresponding to the key information is the switching operation of the display content, determining the display content to be switched according to the key information, wherein the switching operation of the display content is page switching, and the page switching comprises a page turning list, a webpage, a picture and the like; the page switching comprises switching from one complete page to another complete page and also comprises forward movement, backward movement or left-right movement on the same page; in a specific implementation, the page switching operation may include: page switching direction, page switching number, proportional page turning and the like. Further, since the page is composed of a plurality of page elements included therein, such as text, pictures, audio, video, page animation, page components (buttons, icons) and the like that can be operated to provide corresponding interactive functions. Therefore, when page switching is executed, the display content to be switched needs to be determined first, and if the display content to be switched is the text information in the switching page at present, the input text information is acquired according to the key information, and if the text information in the page is "LCD" and the input text information is "display of LCD", the "LCD" is switched to "display of LCD". And the control system sends the switched display content information to the HMI human-machine interface so that the HMI human-machine interface displays the switched page content.
According to the embodiment, the display parameter modification operation and the page switching operation corresponding to the key information are executed at the control system end, so that the HMI man-machine interface only realizes the display function, the software complexity is reduced, the software maintenance is facilitated, the customization and modification are simple, and the production and inventory management are facilitated.
