Description

Technical Field

[0001] This invention relates to an embedded device human-computer interaction system and method, belonging to the field of embedded device technology in the power industry. Background Technology

[0002] As the market continues to expand, the application scenarios of embedded devices in the power industry are increasing. From traditional protection and control to new energy distribution networks, different scenarios have put forward richer display requirements for the human-machine functions of the devices.

[0003] Currently, embedded devices in the power industry generally adopt a system framework that separates the human-machine interface program from the device's business program. That is, the human-machine interface program runs on one MCU or CPU, while the device's business program runs on another CPU, and the two communicate with each other through serial port / Ethernet / internal bus. Under this framework, the software is mainly implemented in two ways: Method 1, the human-machine display program presets some command messages, and the data service module in the device business program sends the corresponding command messages according to the content to be drawn, specifying the coordinates and display content (symbols or text) in the messages. In this mode, it is generally necessary to preset the drawing method of graphic elements / device symbols or achieve the preset effect by interacting with graphic element / device description information files during the initialization phase. When adding complex graphic elements and their operation logic, both the human-machine display program and the device business program need to be upgraded at the same time, resulting in a large development workload; Method 2, the human-machine display program uses a GUI framework to run some file / information parsing modules, data processing modules, function execution modules, etc. When adding new functions, it is often necessary to modify the graphic configuration file, data processing and execution units at the same time. The modifications involve many modules, and as the functions become more and more complex, the program size of its data processing unit and execution unit will also become larger and larger, resulting in high code complexity, reduced reliability, and impact on development efficiency. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an embedded device human-computer interaction system and method that can configure each business unit according to actual needs, effectively reduce the scale of the human-computer program, and reduce code complexity and improve development efficiency when adding new human-computer business functions because they are not coupled with other business functions.

[0005] To achieve the above objectives, the present invention is implemented using the following technical solution:

[0006] In a first aspect, the present invention provides a human-computer interaction method for an embedded device, executed by the embedded device, comprising:

[0007] Receive configuration information files and various human-machine interface service units;

[0008] The human-machine scheduling unit requests configuration information files and human-machine business unit files from the management service unit of the service terminal, and generates an entry interface based on the configuration information files.

[0009] The human-machine scheduling unit receives and processes external operation events, determines the human-machine business unit associated with the operation object, executes and transfers human-machine control to the associated human-machine business unit, and the human-machine business unit communicates independently with the data service unit of the service terminal to complete data acquisition and setting, refresh the display interface and receive and process external operation events.

[0010] When the current interface is exited, the human-machine business unit exits and returns human-machine control to the human-machine scheduling unit. The human-machine scheduling unit then displays the entry interface and waits for the operator's next operation.

[0011] Furthermore, the human-machine scheduling unit requests configuration information files and human-machine business unit files from the management service unit of the service terminal, and generates an entry interface based on the configuration information files, including:

[0012] S1. The human-machine scheduling unit first requests the configuration information file verification code from the management service unit of the service terminal and compares it with the local verification code. If the two are consistent, S2 is executed directly; if the two are inconsistent, the configuration information file is requested from the management service unit.

[0013] S2. The human-machine scheduling unit parses the configuration information file and requests the verification code of the associated human-machine business unit from the management service unit according to the actual associated human-machine business unit. It then compares the verification code with the verification code of the local human-machine business unit file. For human-machine business units whose verification codes match, no processing is performed. For human-machine business units whose verification codes do not match, the human-machine scheduling unit requests the latest human-machine business unit file from the management service unit.

[0014] S3. After all human-machine business unit files are processed, the human-machine scheduling unit generates an entry interface based on the menu structure in the configuration information file and responds to external operation events of the operator on the entry interface.

[0015] Furthermore, the human-machine business unit is obtained through interaction between the human-machine scheduling unit and the management service unit, and the human-machine business unit completes the drawing of the current interface, information interaction with the data service unit, and execution of its own logical functions based on its own code implementation.

[0016] Furthermore, the configuration information file is configured and generated by the operator and includes menu names and their associated human-machine business unit information and verification code information. The menu names and their associated human-machine business unit information are used by the human-machine scheduling unit of the human-machine terminal to form an entry interface, and the verification code information is used to verify whether the file has been changed.

[0017] Furthermore, the data service unit receives message information from the human-machine interface unit, organizes response data, and performs data setting operations.

[0018] Furthermore, when the human-machine interface function needs to be modified, the embedded device receives the modified human-machine interface unit according to the actual needs; when the human-machine interface function needs to be added, the embedded device receives the newly added human-machine interface unit and the modified configuration information file.

[0019] Furthermore, the system receives newly added human-machine interface business units and modified configuration information files, including: after implementing interface drawing, data interaction with data service units, and business logic functions in the new human-machine interface business units according to functional requirements, modifying the configuration information file, and adding the newly added human-machine interface business units to appropriate positions in the menu organization structure of the configuration information file for use as the entry interface display at the start of runtime.

[0020] In a second aspect, the present invention provides an embedded device human-computer interaction system, comprising:

[0021] Data receiving module: used to receive configuration information files and various human-machine interface business units;

[0022] Human-Machine Scheduling Unit: Used to request configuration information files and human-machine business unit files from the management service unit of the service terminal, and generate an entry interface based on the configuration information files; receive and process external operation events, determine the human-machine business unit associated with the operation object, execute and transfer human-machine control to the associated human-machine business unit;

[0023] Human-Machine Service Unit: Used to communicate independently with the data service unit of the service terminal, complete data acquisition and setting, refresh the display interface and receive and process external operation events; when exiting the current interface, the human-machine service unit exits and returns human-machine control to the human-machine scheduling unit, wherein the human-machine scheduling unit displays the entry interface and waits for the operator's next operation.

[0024] Thirdly, the present invention provides an embedded human-computer interaction device, including a processor and a storage medium;

[0025] The storage medium is used to store instructions;

[0026] The processor is configured to operate according to the instructions to perform the steps of the method according to any of the foregoing.

[0027] Fourthly, the present invention provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of any of the methods described above.

Within the aforementioned system framework, it proposes an embedded human-computer interaction method that improves development efficiency when adding or modifying human-computer functions.

[0033] Figure 4 This is a flowchart illustrating the process of adding new business functions as provided in Embodiment 1 of the present invention. Detailed Implementation

[0034] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0035] Example 1:

[0036] like Figure 1 and Figure 2 As shown, this embodiment provides a human-machine interaction method for an embedded device. The embedded device includes a service terminal and a human-machine terminal. The service terminal includes a data service unit, a management service unit, and a storage medium for storing configuration information files and human-machine business unit files. The human-machine terminal initially only has a human-machine scheduling unit. The human-machine business units in the running phase are obtained by the interaction between the human-machine scheduling unit and the management service unit in the initialization phase.

[0037] The human-machine scheduling unit of the human-machine terminal is an independent program running on the terminal. It draws the entry interface based on a configuration information file (this file, configured and generated by the operator, includes menu names, associated human-machine service unit information, and verification code information; the menu names and associated human-machine service unit information are used by the terminal's scheduling unit to form the entry interface, and the verification code information is used to verify whether the file has been modified). During the display of the entry interface, it responds to external operation events and schedules and executes relevant human-machine service units. Each human-machine service unit is an independently running program used for drawing the interface of a specific human-machine service function, communicating with the data service unit to acquire and set data, and executing business logic. Each human-machine service unit corresponds to a specific human-machine service function, and each device has multiple human-machine service functions, including but not limited to status viewing, setting values, command execution, and waveform display. The data service unit receives message information from the human-machine service units, organizes response data, and executes data setting operations.

[0038] This method includes the following steps:

[0039] Step (A): Configure the HMI menu and its HMI business units according to actual needs and generate a configuration information file. Download the configuration information file and each HMI business unit to the embedded device.

[0040] Step (B), the embedded device startup initialization phase, involves the human-machine terminal's human-machine scheduling unit requesting configuration information files and human-machine business unit files from the service terminal's management service unit, and generating an entry interface based on the configuration information files, such as... Figure 3 As shown, it includes the following steps:

[0041] (B1) The human-machine scheduling unit of the human-machine terminal first requests the configuration information file verification code from the management service unit of the service terminal and compares it with the local verification code. If the two are consistent, it will directly execute (B2); if the two are inconsistent, it will request the configuration information file from the management service unit.

[0042] (B2) The human-machine scheduling unit parses the configuration information file and requests the verification code of the associated human-machine business unit from the management service unit according to the actual associated human-machine business unit. It then compares the verification code with the verification code of the local human-machine business unit file. If the verification code comparison results are consistent, no processing is performed. If the verification code comparison results are inconsistent, the human-machine scheduling unit requests the latest human-machine business unit file from the management service unit.

[0043] (B3) After all the human-machine business unit files are processed, the human-machine scheduling unit generates an entry interface based on the menu structure in the configuration information file and responds to the operator's mouse, keyboard, touch screen and other events on the entry interface.

[0044] The human-machine scheduling unit of the human-machine terminal uses a verification code to determine whether it is necessary to reread the configuration information file and human-machine business unit file from the management service unit. This avoids re-acquiring them every time the terminal starts, reduces unnecessary information interaction, and ensures security and reliability.

[0045] Step (C), the embedded device operation phase: The human-machine terminal's human-machine scheduling unit executes the corresponding human-machine service unit based on the operator's selection. The human-machine service unit, according to its own code implementation, completes the drawing of the current interface, information interaction with the data service unit, and execution of its own logical functions. Specifically: the human-machine terminal's human-machine scheduling unit receives and processes external operation events, determines the human-machine service unit associated with the operation object, executes and transfers human-machine control to the associated human-machine service unit, and the human-machine service unit independently communicates with the data service unit of the service terminal to complete data acquisition and setting, refreshes the display interface, and receives and processes external operation events, including keyboard operation events, mouse operation events, and touchscreen operation events.

[0046] In step (D), during the embedded device operation phase, if the current interface is exited, the current human-machine business unit will exit and hand over human-machine control to the human-machine scheduling unit, which will then display the entry interface and wait for the operator's next operation.

[0047] Step (E): If it is necessary to modify the existing human-machine business functions, simply modify the corresponding human-machine business unit and download the updated human-machine business unit to the device.

[0048] Step (F): If new human-machine business functions are needed, a new human-machine business unit is added to implement the new business functions, such as... Figure 4 As shown, it includes the following steps:

[0049] (F1) Implement interface drawing, data interaction with the data service unit, and business logic functions in the new human-machine business unit according to functional requirements.

[0050] (F2) Modify the configuration information file and add the newly added human-machine business unit to the appropriate position in the menu organization structure of the configuration information file for display on the entry interface when the program starts running.

[0051] (F3) Download the newly added human-machine business unit and the modified configuration information file to the device.

[0052] When it is necessary to modify or add a certain human-machine business function, only one human-machine business unit needs to be operated. This human-machine business unit can independently complete the various requirements of the human-machine business function without relying on other human-machine business units, thereby reducing the coupling with other modules and helping to improve code reliability.

[0053] This method can configure each business unit according to actual needs, effectively reducing the size of the human-machine program. When adding new human-machine business functions, it reduces code complexity and improves development efficiency because it is not coupled with other businesses.

[0058] Human-Machine Service Unit: Used to communicate independently with the data service unit of the service terminal, complete data acquisition and setting, refresh the display interface and receive and process external operation events; when exiting the current interface, the human-machine service unit exits and returns human-machine control to the human-machine scheduling unit, wherein the human-machine scheduling unit displays the entry interface and waits for the operator's next operation.

[0066] When the current interface is exited, the human-machine business unit exits and returns human-machine control to the human-machine scheduling unit. The human-machine scheduling unit then displays the entry interface and waits for the operator's next operation.
