[0002] As a human-machine interface device for the inverter, the LCD keypad displays function codes corresponding to the inverter it's paired with. This function code information is typically stored in an external memory chip, such as a Flash chip or SD (Secure Digital) card. Normally, each LCD keypad stores one copy of function code information, matching it to a specific inverter model. This ensures that the displayed content corresponds exactly to the inverter's functions. However, this approach reduces the versatility of LCD keypads.

DETAILED DESCRIPTION

[0028] The embodiments of the present invention provide a method and device for processing information of a liquid crystal keyboard, and a liquid crystal keyboard, which are beneficial to improving the versatility of the liquid crystal keyboard and reducing the difficulty and cost of maintenance.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0030] It should be noted that to improve the versatility of LCD keyboards, related art proposes storing all function code information corresponding to various inverter models in an external memory chip. After an inverter is connected to the LCD keyboard, the LCD keyboard can select and display the matching function code information from all the function code information stored in the external memory chip. However, this approach requires the external memory chip to have sufficient storage space to store all the function code information for all inverter models, which places a high demand on the LCD keyboard's storage space. Furthermore, if the function code information of an inverter needs to be added, deleted, or modified, all the function code information of the inverter needs to be deleted or modified, which results in long data burning time and inconvenient maintenance.

[0031] In view of this, an embodiment of the present invention provides an information processing method for a liquid crystal keyboard, which is applied to a liquid crystal keyboard. Figure 1 , Figure 1 This is a flow chart of an information processing method for a liquid crystal keyboard provided by an embodiment of the present invention. The method includes the following S110 to S120.

[0032] S110: When it is detected that the target inverter is connected, obtaining difference code data of the target inverter; the difference code data includes at least one function code information unique to the model and software version number of the target inverter.

[0033] The target inverter refers to the inverter currently connected to the LCD keyboard. That is, the LCD keyboard can be used with multiple inverters. When the LCD keyboard detects that an inverter is powered on, it indicates that an inverter is connected, and the connected inverter is the target inverter. It should be noted that in order to reduce the storage space occupied by the LCD keyboard's external memory chip, considering that different inverter models may have the same function code information or different function code information, the function code information shared by all inverter models can be extracted to form reference code data, and this reference code data is stored in the LCD keyboard's external memory chip. The function code information unique to each inverter of different models and software versions is extracted to form difference code data corresponding to the inverter of that model and software version. This difference code data is pre-stored on the inverter side. In this way, each inverter can store its own unique difference code data, which includes at least one function code information unique to the inverter model and software version.

[0034] S120: Displaying the function code of the target inverter according to the difference code data and the reference code data; the reference code data includes the function code information shared by inverters of different models.

[0035] Specifically, after the liquid crystal keyboard obtains the difference code data of the target inverter, it can further display the function code of the target inverter according to the difference code data and the reference code data stored in the external storage chip of the liquid crystal keyboard.

[0036] In this application, an external storage chip (such as a flash chip) on the LCD keyboard side is used to store the reference code data, and each inverter stores its own unique differential code data. On the one hand, since the external storage chip on the LCD keyboard side only needs to store the reference code data and does not need to store the differential code data of each inverter, the amount of data stored in the external storage chip of the LCD keyboard can be reduced, requiring less space on the storage chip, which helps reduce costs. On the other hand, if the function code information of the inverter needs to be added, deleted, or modified, only the differential code data stored on the inverter side needs to be maintained, and there is no need to maintain the reference code data stored in the external storage chip of the LCD keyboard, thus reducing the difficulty and cost of maintenance.

[0037] In one embodiment, see Figure 2 In the above S110, when the target inverter is detected to be connected, the process of obtaining the difference code data of the target inverter may include:

[0038] S210: When it is detected that the target inverter is connected, the product model identification and software version number of the target inverter are obtained.

[0039] It should be noted that, in an embodiment of the present invention, when the target inverter is detected to be connected, the product model identification (i.e., product model ID code) and software version number of the target inverter can be obtained, wherein the product model identification can be used to characterize the model of the target inverter, that is, the model of the target inverter can be determined through the product model identification of the target inverter.

[0040] S220: When the product model identification code of the target inverter is consistent with the product model identification of the inverter connected last time, and the software version number of the target inverter is consistent with the software version number of the inverter connected last time, the difference code data of the inverter connected last time is used as the difference code data of the target inverter.

[0041] It should be noted that in actual applications, a small amount of storage space can be allocated on the external memory chip on the LCD keyboard side to store the product model identifier and software version number of the target inverter connected to the LCD keyboard, as well as the corresponding difference code data. In order to reduce the number of data uploads during the target inverter's power-up process, in this embodiment of the present invention, after obtaining the product model identifier (i.e., product model ID code) and software version number of the target inverter, the product model identifier and software version number of the target inverter can be compared with the product model identifier and software version number of the inverter last connected to the LCD keyboard, where the product model identifier and software version number of the inverter last connected are already stored in the preset storage space of the LCD keyboard's external memory chip. If the product model identifier of the inverter that was last connected to the LCD keyboard is consistent with the product model identifier of the target inverter, and the software version number of the inverter that was last connected to the LCD keyboard is also consistent with the software version number of the target inverter, then it means that the model and software version number of the inverter that was last connected to the LCD keyboard are the same as the target inverter that is currently connected, and the difference code data of the target inverter that is currently connected is also the same as the difference code data of the inverter that was last connected. Therefore, there is no need to re-acquire the difference code data of the target inverter. The difference code data of the inverter that was last connected can be directly used as the difference code data of the target inverter. Specifically, the stored difference code data corresponding to the product model identifier and software version number can be obtained from the external storage chip of the LCD keyboard.

[0042] S230: When the product model identification code of the target inverter is inconsistent with the product model identification of the inverter connected last, and / or the software version number of the target inverter is inconsistent with the software version number of the inverter connected last, obtain difference code data from the target inverter.

[0043] It is understandable that if it is determined through comparison that the product model identification code of the target inverter is inconsistent with the product model identification of the inverter that was last connected to the LCD keyboard, and / or the software version number of the target inverter is inconsistent with the software version number of the inverter that was last connected to the LCD keyboard, that is, if at least one of the product model identification code and the software version number is inconsistent, then it means that the model and software version number of the inverter that was last connected to the LCD keyboard are inconsistent with the model or software version number of the target inverter that is currently connected. At this time, it can be determined that the difference code data of the inverter that was last connected is different from the difference code data of the target inverter that is currently connected, so it is necessary to obtain the difference code data of the target inverter. Specifically, the LCD keyboard can send a request to obtain the difference code data to the target inverter. After receiving the request to obtain the difference code data, the target inverter uploads the difference code data stored in the target inverter itself to the LCD keyboard according to the request to obtain the difference code data.

[0044] In one embodiment, after obtaining the difference code data from the target converter in S110, the method may further include: The product model identification, software version number and corresponding difference code data of the inverter recorded last time are overwritten and updated based on the product model identification, software version number and difference code data of the target inverter.

[0045] It is understood that in practical applications, in order to facilitate the LCD keyboard to quickly determine whether to obtain the differential code data of the detected target inverter the next time it detects a connected inverter, after obtaining the differential code data of the connected target inverter, the product model identification, software version number, and differential code data of the target inverter can be stored in the corresponding storage space of the external memory chip on the LCD keyboard side, and the product model identification, software version number, and differential code data of the previously connected inverter can be overwritten and updated. In other words, considering that the LCD keyboard can only be used with one inverter at a time, it is only necessary to store the differential code data of the currently connected target inverter. Therefore, the product model identification, software version number, and differential code data of the currently connected target inverter can be used to overwrite the product model identification, software version number, and differential code data stored in the external memory chip on the LCD keyboard side. This not only ensures that the LCD keyboard is configured with only one inverter at a time, but also reduces storage space usage. In practical applications, the liquid crystal keyboard in the embodiment of the present invention only needs to allocate a small piece of memory from the memory chip to store a copy of the difference table data, thereby avoiding the continuous increase of the storage space occupied by the data and helping to reduce costs.

[0046] The following is an introduction to the LCD keyboard function code display process, please refer to Figure 3In one embodiment, the process of displaying the function code of the target inverter according to the difference code data and the reference code data in S120 may include the following steps.

[0047] S310: In response to a keyboard operation on a target inverter, obtaining a target function code number corresponding to the keyboard operation.

[0048] It should be noted that when the user uses the LCD keyboard to operate the inverter, the user will select the function code operation corresponding to the LCD keyboard. For the LCD keyboard, in response to the user's keyboard operation action on the target inverter through the LCD keyboard, the corresponding target function code number can be obtained according to the keyboard operation.

[0049] S320: Determine target function code information corresponding to the target function code number from the difference code data and the reference code data according to the target function code number.

[0050] It can be understood that after the LCD keyboard obtains the target function code number corresponding to the current keyboard operation, it can find the target function code information corresponding to the target function code number from the difference code data and reference code data stored in the external storage chip of the LCD keyboard based on the target function code number.

[0051] S330: Display based on the target function code information.

[0052] Specifically, after obtaining the target function code information corresponding to the target function code number, a corresponding display can be further performed based on the target function code information. The function code information in the embodiment of the present invention may include the function code number and function code content information, and the function code content information may include description information of the function code, detailed parameter description information of the function code, and the display type corresponding to the function code. In actual application, the liquid crystal keyboard can determine the corresponding target function code number based on the user's keyboard operation, and then determine the corresponding target function code information from the difference code data and the reference code data based on the target function code number, and then display the function code content information in the target function code information.

[0053] In one embodiment, see Figure 4 The process of determining the target function code information corresponding to the target function code number from the difference code data and the reference code data in the above S320 according to the target function code number may include the following S410 to S440.

[0054] S410: Determine whether there is target function code information corresponding to the target function code number in the difference code data.

[0055] It should be noted that in order to reduce the number of queries and improve information processing efficiency in the embodiment of the present invention, the target function code number can be compared with the function code numbers in each function code information in the difference code data to determine whether there is a target function code information corresponding to the target function code number in the difference code data.

[0056] S420: When the target function code information exists in the difference code data, the target function code information is acquired from the difference code data.

[0057] It can be understood that if there is a function code number consistent with the target function code number in the various function code information in the difference code data, the function code information corresponding to the function code number will be used as the target function code information, and the determined target function code information will be obtained from the difference code data, and the function code content information in the target function code information will be displayed.

[0058] S430: When the target function code information does not exist in the difference code data, determine whether the target function code information exists in the reference code data.

[0059] Specifically, if the function code numbers in each function code information in the difference code data are inconsistent with the target function code number, it means that there is no target function code information matching the target function code number in the difference code data. At this time, the target function code number can be compared with the various function code information in the reference code data to determine whether there is target function code information corresponding to the target function code number in the reference code data.

[0060] S440: When the target function code information exists in the reference code data, the target function code information is obtained from the reference code data.

[0061] That is to say, the target function code number can be compared with the function code numbers in all function code information in the benchmark code data. If there is a function code number consistent with the target function code number, it means that there is a target function code information corresponding to the target function code number in the benchmark code data. That is, the function code information corresponding to the function code number in the benchmark code data is used as the target function code information, and the target function code information is obtained from the benchmark code data, and the function code content information in the target function code information is displayed.

[0062] It should be noted that the difference code data stores function code information unique to the target inverter model and software version, while the reference code data stores function code information common to inverters of different models. For the currently detected target function code number, if target function code information corresponding to the target function code number exists in both the reference code data and the difference code data, and the function code content of the target function code information in the difference code data differs from the function code content of the target function code information in the reference code data, this indicates that the target function code number in the target inverter has been redefined, and the function code content of the target function code information corresponding to the target function code number has changed compared to the universal function code content. In this case, the target function code information corresponding to the target function code number in the difference code data shall prevail.

[0063] It is understood that in the embodiment of the present invention, the target function code number is first compared with each function code information in the difference code data. If no corresponding target function code information exists, the target function code number is then compared with each function code information in the reference code data. This allows the target function code information corresponding to the target function code number to be quickly and efficiently acquired. In addition, if the reference code data is first determined to determine whether the target function code information corresponding to the target function code number exists, then regardless of whether the reference code data contains the corresponding target function code information, it is necessary to check whether the target function code information corresponding to the target function code number exists in the difference code data. If the target function code information exists in the difference code data, the target function code information retrieved in the difference code data shall prevail; if the target function code information does not exist in the difference code data, the target function code information retrieved in the reference difference code data shall prevail. Although the target function code information corresponding to the target function code number can be accurately determined, the reference code data is queried first. Regardless of whether the target function code information corresponding to the target function code number exists, the difference code data needs to be queried again, and the number of queries is large. However, if the difference code data is queried first, when the target function code information corresponding to the target function code number exists in the difference code data, there is no need to query the reference code data again. Therefore, the query efficiency and display efficiency can be improved, and resources can also be saved.

[0064] Additionally, the method may further include: When the target function code information does not exist in either the difference code data or the reference code data, the numerical value corresponding to the target function code number is displayed.

[0065] It is understandable that if the target function code information corresponding to the target function code number cannot be found in both the difference code data and the reference code data, it means that the currently obtained difference code data is incomplete, resulting in the target function code number not being able to be found. At this time, the target function code number can be neutralized, that is, the numerical value corresponding to the target function code number is displayed, and other function code content information is not displayed, so that after the staff sees the numerical value display, they can determine that the target function code information corresponding to the target function code number is missing in the difference code data of the target inverter. At this time, feedback can be given to the manufacturer for supplementary maintenance of the difference code data of the target inverter.

[0066] In one embodiment, see Figure 5 When it is detected that the target inverter is connected, before obtaining the difference code data of the target inverter, the method may further include the following S510 to S530.

[0067] S510: Obtain the overall functional specifications of the target inverter and the benchmark functional specifications shared by inverters of different models; the overall functional specifications and the benchmark functional specifications are both in the first data format; the benchmark code table data and the difference code table data are both in the second data format; the overall functional specifications include all functional code information of the target inverter, and the benchmark functional specifications include functional code information shared by inverters of different models.

[0068] It should be noted that for each inverter model, an overall functional specification can be pre-determined, as well as benchmark functional specifications corresponding to various inverter models. The overall functional specification includes all function code information for the corresponding inverter, while the benchmark functional specification includes all function code information shared by inverters of different models. Both the overall functional specification and the benchmark functional specification are in a first data format (e.g., Word format), while the benchmark code table data and the difference code table data are in a second data format (e.g., Excel format). This embodiment of the present invention uses a target inverter as an example to obtain the overall functional specification of the target inverter and the benchmark functional specifications shared by inverters of different models.

[0069] S520: Compare each function code information in the overall function specification with each function code information in the benchmark function specification.

[0070] Specifically, in an embodiment of the present invention, a function code information can be used as the minimum comparison unit, and the function code number of the first function code information can be obtained from the overall function specification data. Then, the function code number is compared with the function code numbers of all function code information in the benchmark function specification. If the benchmark code data contains first function code information corresponding to the function code number, it is further determined whether there is second function code information with the same function code content information as the first function code information in each first function code information in the benchmark code data. If so, it means that the first function code information is a universal function code information. At this time, the first function code information can be skipped, and the function code number of the next function code information can be obtained from the overall function specification of the target inverter. The function code number of the second function code information is continued to be compared with the function code numbers of all function code information in the benchmark code specification until all function code information is compared.

[0071] S530: Determine the function code information set in the overall function specification that is different from each function code information in the benchmark function specification as the difference code data of the target inverter; wherein the different function code information refers to at least one difference in the function code number or the function code information content in the function code information.

[0072] It should be noted that if the compared function code number does not exist in the benchmark function specification or the function code number exists but the second function code information that is consistent with the function code content information of the first function code information does not exist in each first function code information, then the first function code information difference code data is used to obtain the function code number of the next function code information, and the function code number of the next function code information is compared with the function code numbers of all function code information in the benchmark function specification until all function code information in the entire function specification is compared. Finally, the difference code data is obtained. The difference code data can be a difference table in Excel format, and the difference table stores each function code information unique to the target inverter.

[0073] It should also be noted that, in this embodiment, for ease of display, the Word-formatted benchmark function specifications can also be converted into an Excel-formatted benchmark table. Specifically, the benchmark code data is an Excel-formatted benchmark table, which includes all function code information common to all inverter models. Furthermore, the Excel-formatted benchmark table and difference table can be converted, respectively, into address-addressed Unicode-encoded bin-formatted benchmark and difference tables via a host computer. The bin-formatted benchmark table and dot matrix font library can be combined into a final bin file and burned into a memory chip for data storage. The bin-formatted difference table and dot matrix font library can then be combined into a final bin file. Since the function code content displayed on the LCD keyboard includes Chinese, English, numbers, or other foreign languages, and Unicode is a universal encoding system where each character has a unique encoding, converting the difference table and benchmark table data into address-addressed Unicode-encoded bin files allows the LCD keyboard to recognize content in all different languages ​​using only one set of Unicode encoding, thereby improving its versatility.

[0074] In one embodiment, the method may further include: After determining the difference code data of the target frequency converter, compressing the difference code data; The compressed difference code data is stored in the target inverter.

[0075] It can be understood that in order to reduce the storage space occupied and data upload time in the embodiment of the present invention, after the difference code data of the target inverter is determined through the above-mentioned process S510 to S530, the difference code data can be compressed (for example, compressed to about 1 / 5 of the original data), and then the compressed difference code data can be stored in the corresponding target inverter.

[0076] In other words, to reduce storage space usage, this embodiment can employ data compression techniques to compress the difference table data. For example, the data can be compressed to approximately one-fifth of its original size. The compressed difference table data is then transferred to the inverter for storage, thereby reducing storage space and data transmission volume. The reference code data in this embodiment can be stored uncompressed and stored in the LCD keyboard's memory chip, serving as a base table for all inverter models. This storage method allows each inverter to store only one copy of the compressed difference code data, while the LCD keyboard only needs to store one copy of the reference code data. This significantly reduces storage space and lowers maintenance costs.

[0077] Then, the corresponding process of obtaining the difference code data from the target inverter in S230 may include: Obtain compressed difference code data from the target inverter, and store the compressed difference code data in a storage space that is lost upon power failure; The compressed difference code data is decompressed to obtain the difference code data of the target inverter.

[0078] It can be understood that the difference code data obtained by the LCD keyboard from the target inverter is compressed difference code data. Considering that the compressed difference code data is only used for transition, it does not need to be retained all the time. Therefore, before storing the compressed difference code data in the external storage chip of the LCD keyboard, the compressed difference code data can be first stored in the RAM storage space of the LCD keyboard that is lost when the power is off, and then the compressed difference code data is decompressed to obtain the difference code data of the target inverter, and the decompressed difference code data and the corresponding product model identification and software version number are stored in the external storage chip of the LCD keyboard.
