Description
Technical Field
[0001] This invention relates to the field of numerical control technology, and more specifically, to a general numerical control system keyboard design method and system. Background Technology
[0002] The CNC keyboard in a CNC system serves as a crucial interface for human-machine interaction. It consists of letter keys, function keys, and number keys. It is used for programming machining operations, modifying parameters, and facilitating functional operations between the operator and the system. There are many types of CNC machine tools, including major categories such as lathes, milling machines, grinders, punching machines, and planers, as well as subcategories within each major category. The operating methods for each model differ.
[0003] The row and column matrix of the CNC system keyboard panel varies depending on the machine model. In product development, the key value definitions for CNC keyboards differ, so CNC system keyboard designs typically employ different key value definitions to adapt to different machine models. The hardware of the CNC keyboard requires modification of firmware code to match the key row and column matrix on the keyboard panel and to change the key values corresponding to each key position. Furthermore, the hardware of CNC keyboards generally uses FPGA or MCU units, whose code programming is relatively complicated, and each firmware code change requires retesting, thus increasing development and debugging costs.
[0004] Therefore, when the hardware structure of the keyboard panel in a commonly used CNC system is adjusted according to different machine models, the hardware needs to be re-modified, including the key row and column matrix and the key value definition of each key, and the firmware code needs to be re-flashed. When the key presses on the CNC system keyboard change, the key value is written to an input report and sent to the CNC system software, which then responds to the key event. This process is cumbersome, inefficient, costly, and difficult to promote and apply. Summary of the Invention
[0005] This invention addresses the technical problem of existing CNC system keyboards, which require adjustments to the hardware structure of the keyboard faceplate according to different models. This necessitates modifying the key row and column matrix and the key value definition of each key, as well as re-burning the firmware code, resulting in low efficiency and high cost.
[0006] This invention provides a general CNC system keyboard design method comprising the following steps:
[0007] S1, Configure the key states and key events of the keys on the keyboard of each CNC system into a key value mapping table;
[0008] S2, Read the real-time status of the keys on the CNC system keyboard and write the real-time status of the keys into the key input report;
[0009] S3, parse the real-time status data of the keys in the key input report, and search for the corresponding key event in the key value mapping table;
[0010] S4 translates the searched key events into standard key values that the current CNC system can recognize, and defines new keys based on the standard key values.
[0011] Preferably, S1 specifically includes:
[0012] Define the key states of the keys on the keyboard of different CNC systems, translate the actual execution actions represented by the key states of each CNC system into key events, and form a key-value mapping table by mapping the key states to key events.
[0013] Preferably, each actual action corresponds to at least one key state, and the actual action corresponds one-to-one with the key event.
[0014] Preferably, the real-time status of the buttons in S2 specifically includes: the row and column of the button whose status has changed on the CNC system keyboard, and the state of the button being pressed or released.
[0015] Preferably, the step S2 of writing the real-time status of the key to the key input report specifically includes:
[0016] Based on the maximum single data reception capacity of the current CNC system, all transmittable key states are packaged and written into a key input report in chronological order within this unit capacity.
[0017] Preferably, step S5 is included after step S4:
[0018] Once the states of all buttons in a CNC system are defined, a new universal keyboard is obtained. Based on the new universal keyboard, the real-time states of the buttons in the next CNC system are integrated into the new universal keyboard.
[0019] Preferably, the fusion process in S5 specifically includes:
[0020] Based on the key value mapping table, the key status under the current CNC system is translated into the corresponding key event, and the corresponding new key on the new universal keyboard is searched through the standard key value corresponding to the key event.
[0021] If no corresponding new key is found, a new key will be added to correspond to the standard key value.
[0022] If a corresponding new key is found, a correspondence is established between the new key and the standard key value.
[0023] This invention also provides a universal CNC system keyboard design system, the system being used to implement a universal CNC system keyboard design method, comprising:
[0024] The mapping establishment module is used to configure the key states and key events of the keys on the keyboard of each CNC system into a key-value mapping table;
[0025] The report caching module is used to read the real-time status of the keys on the CNC system keyboard and write the real-time status of the keys into the key input report.
[0026] The report parsing module is used to parse the real-time status data of the keys in the key input report and search for the corresponding key events in the key value mapping table.
[0027] The keyboard definition module is used to translate the searched key events into standard key values that the current CNC system can recognize, and define new keys based on the standard key values.

The method includes the following steps: configuring the key states and key events of each CNC system keyboard into a key value mapping table; reading the real-time key states of the current CNC system keyboard and writing them into a key input report; parsing the real-time key state data in the key input report and searching for the corresponding key events in the key value mapping table; translating the searched key events into standard key values that the current CNC system can recognize, and defining new keys based on the standard key values. This solution only needs to record the position and pressed / released state of the keys on the CNC system keyboard, and then obtain the corresponding key values by combining the key value mapping configuration, thereby adapting to the needs of different CNC system keyboards and simplifying the CNC system keyboard design process. The configurable key value mapping table meets the needs of different users for CNC system keyboards; it greatly reduces R&D and debugging costs, reduces frequent changes to key value definitions based on different needs, and also reduces changes to the firmware code of the CNC system keyboard, thus reducing costs.

[0040] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.
[0041] like Figure 1 and Figure 2 As shown, the present invention provides a general CNC system keyboard design method, comprising:
[0042] First, configurations are made according to different CNC systems, mapping the key states and key events on the keyboard of each CNC system into a key-value mapping table. Specifically, the key states on the keyboards of different CNC systems are defined, and the actual execution actions represented by the key states in each CNC system are translated into key events. The key states and key events are then mapped to form a key-value mapping table. Each actual execution action corresponds to at least one key state, and there is a one-to-one correspondence between the actual execution action and the key event.
[0043] The key state mapping file can be configured for different products to simultaneously meet the keyboard requirements of CNC systems for various products. Even if the key states are the same across different CNC systems, the matched key events may differ. In other words, in the key value mapping table, one key event can correspond to different key states, and the actual execution action (key event) behind these key states is the same.
[0044] Suppose that there is a button named X1 in CNC milling machine system A and a button named Y1 in CNC lathe system B. Although the names of these two buttons are different, pressing these two buttons both represent pausing. In this case, the button press state of these two buttons can be mapped to the pausing button event.
[0045] Therefore, during configuration, it is necessary to match the actual actions behind the key states, correspond the actual actions expressed by the key states, and match key states with the same actual actions to form a key-value mapping table.
[0046] Secondly, when the key status on the CNC system keyboard changes, the real-time key status is recorded, including the key's row, column, and whether it is pressed or released, and written to the key input report. The key input report acts as an intermediary, storing key statuses and transmitting them to the CNC system. The data is transmitted in the chronological order of key status changes for easier processing by the CNC system.
[0047] The system analyzes the real-time button status data in the button input report and searches for the corresponding real-time button event in the key value mapping table. Each real-time button event corresponds to a standard key value, which is the button status information that the CNC system can recognize. A unique action can be executed based on the standard key value. Therefore, as long as the CNC system can obtain the standard key value, it can execute the button event corresponding to that button status.
[0048] Finally, the real-time button events are translated into standard key values that the current CNC system can recognize, and new buttons are defined based on these standard key values. The button input report is then sent to the CNC system software. When the CNC system software receives the button data, it parses the button state data and finds the corresponding standard key value in the button state mapping file. Based on this standard key value, a new button is defined. This process is repeated until all current button states can be mapped to a new button, resulting in a complete new universal keyboard. This new universal keyboard, acting as an external keyboard, can then send operation commands to the CNC system. For example, when a new button is pressed, the CNC system can convert the button state of the new button into a standard key value based on the button input report. The CNC system can then execute the corresponding operation based on the button event corresponding to the standard key value.
[0049] Once the button states of a CNC system are defined, a new universal keyboard is obtained. Based on this new universal keyboard, the real-time button states of the next CNC system are integrated into the new universal keyboard. After defining the new buttons for a CNC system according to the above steps, a new universal keyboard can be formed.
[0050] Then, keyboard translation and fusion are performed on other CNC systems. The translation and fusion process specifically includes:
[0051] The key status of the current CNC system is translated into the corresponding key event according to the key value mapping table. The corresponding new key on the new universal keyboard is searched through the standard key value corresponding to the key event. If no corresponding new key is found, a new new key is added to correspond to the standard key value. If a corresponding new key is found, a correspondence is established between the new key and the standard key value.
[0052] Specifically, if a new button event is discovered, such as different operations for lathes and milling machines, a new button needs to be added. The definition of the new button follows the same method described above, and will not be repeated here. If the button event has already been defined, the current real-time state of that button in the current system can be merged into the corresponding new button under the same button event.
[0053] Taking the keyboard of a general-purpose milling machine CNC system as an example, such as Figure 5 As shown, the CNC keyboard hardware only needs to adjust the corresponding row and column matrix according to the hardware structure on the mask. It does not require modification of the specific key state definition for each key. When the key status on the CNC system keyboard changes, the key data (row, column, pressed / released state) is transmitted to the CNC system software. Then, the corresponding standard key is obtained according to the key state mapping table, and the software interface responds to the key event. Through this series of processes, a universal CNC system keyboard is achieved, such as... Figure 2 As shown. In contrast to an external standard keyboard, an external keyboard directly sends standard key presses to the CNC system, and the software interface responds to the corresponding key events.
[0054] The preferred approach, which involves writing the real-time status of the buttons into the button input report, specifically includes:
[0055] Based on the maximum single data reception capacity of the current CNC system, all transmittable key states are packaged and written into a key input report in chronological order within this unit capacity. This saves on the number of data transmissions and improves data transmission efficiency.
[0056] Specifically, when the key state of the CNC system keyboard changes, the row, column, and press / release status information of the key are written into the input report, and the data is transmitted to the CNC system software. Taking the data transmission of USB-HID (Universal Serial Bus-Human Interface Device) devices as an example, USB-HID devices can be divided into low-speed devices, full-speed devices, and high-speed devices according to their transmission speed. Most HID products on the market are low-speed devices. Taking low-speed devices as an example, the maximum data that can be transmitted in each transaction is 8 bytes (Buf[8]). Figure 4 As shown, Buf[0]-Buf[2] can store the row where the key is located, with each 4 bits representing a row of one key, and a maximum of 6 rows of keys can be recorded at the same time. Buf[3]-Buf[5] can store the column where the key is located, with each 4 bits representing a column of one key, and a maximum of 6 columns of keys can be recorded at the same time. Each bit of Buf[6] represents the pressed state of a key, and each bit of Buf[7] represents the released state of a key. Compared with the input report of the standard key, the comparison... Figure 3 and Figure 4 The input report of the new universal keyboard keys can meet the data transmission requirements of the original standard keyboard keys.
[0057] The key state mapping configuration file is configured based on the key states of a standard keyboard (i.e., an existing conventional keyboard), with each key corresponding to a specific key state. When the CNC system software receives key data, it translates the data in the input report into the corresponding standard key state using the key state mapping table. For example... Figure 6 As shown. The button status mapping file can be modified according to different products and different models of CNC systems, such as... Figure 7 As shown, this example uses an XML file format, but is not limited to using XML file format to configure key state mapping files. Figure 8 The CNC milling machine panel shown allows configuration of attributes such as row, column, key, and modifiers in the key state mapping file. The row and column attributes represent the row and column positions of the keys, the key attribute represents the standard key state, and the modifiers attribute represents the key modifiers, enabling the processing of individual or combined keys. Replacing the original method of modifying firmware code to define key states with a key state mapping configuration file provides a more convenient way to handle the needs of different CNC keyboards.
[0058] This invention also provides a universal CNC system keyboard design system, which is used to implement the universal CNC system keyboard design method described above, including:
[0059] The mapping establishment module is used to configure the key states and key events of the keys on the keyboard of each CNC system into a key-value mapping table;

[0066] S4 translates the searched key events into standard key values that the current CNC system can recognize, and defines new keys based on the standard key values.
[0067] Please see Figure 9 This is a schematic diagram illustrating an embodiment of a computer-readable storage medium provided by the present invention. (See diagram below.) Figure 9 As shown, this embodiment provides a computer-readable storage medium 1400, on which a computer program 1411 is stored. When the computer program 1411 is executed by the processor, it performs the following steps: S1, configuring the key states and key events of the keys on each CNC system keyboard into a key-value mapping table.
[0068] S2, Read the real-time status of the keys on the CNC system keyboard and write the real-time status of the keys into the key input report;
