Technical Field

[0001] The present invention relates to circuit control technology, and specifically to a hardware adaptive intelligent control system, method, intelligent key and keyboard. Background Art

[0002] In automation systems, mechatronic control systems, embedded systems, and Internet of Things hardware, controlling subsequent circuits, devices, or programs based on a hardware input circuit is a widely used method. For example, controlling device operation based on keys, switch-type sensors, etc., and controlling devices or inputting information based on a keyboard. In the prior art, related programs or circuit control software are designed for specific circuits and are highly dependent on the circuit structure and its operation mode. Different hardware input circuits require control systems designed with different programs, resulting in complex program design and little generality. Summary of the Invention

[0003] One of the technical problems to be solved by the present invention is to provide a hardware adaptive intelligent control system that can adapt to different hardware input circuits.

[0004] The technical solution adopted by the present invention to solve the above technical problem is: a hardware adaptive intelligent control system, including a hardware circuit information extraction function family, an analysis and judgment function family, and a control instruction generation function family. The hardware circuit information extraction function family, the analysis and judgment function family, and the control instruction generation function family are all composed of function codes and share a data set.

[0005] The hardware circuit information extraction function family extracts the initial state information from the hardware input circuit and saves the information in the shared data set or passes it to the analysis and judgment function family.

[0006] The analysis and judgment function family obtains the current state information of the hardware input circuit, compares the current state information with the initial state information, and saves the judgment result in the shared data set or passes it to the control instruction generation function family.

[0007] The control instruction generation function family generates an execution instruction according to the judgment result of the analysis and judgment function family and passes the execution instruction to the hardware output circuit or the software system receiving the instruction, so that the hardware output circuit or the software system receiving the instruction generates an execution action as required.

[0008] The function codes of the hardware circuit information extraction function family, the analysis and judgment function family, and the control instruction generation function family are all included in the function code library of the intelligent control system, and the functions in the function code library share the same data set.

[0009] Some functions of the hardware circuit information extraction function family are integrated in the analysis and judgment function family to extract the current state information of the hardware input circuit.

[0010] The hardware circuit information extraction function family extracts the initial state information of the hardware input circuit and associates the initial state information with the identification information of the hardware input circuit, where the identification information is used to identify the input unit in the hardware input circuit.

[0011] The identification information is the hardware circuit interface number of the hardware input circuit.

[0012] The analysis and judgment function family compares the current state information with the initial state information, determines the working state of the hardware input circuit according to the comparison result, and further obtains the judgment result for generating an execution instruction based on the working state.

[0013] The working state of the hardware input circuit includes the initial state when there is no input event and one or more change states when an input event occurs; when the hardware input circuit is in the change state, it can generate current state information different from the initial state information. The analysis and judgment function family determines whether the working state of the hardware input circuit has changed by comparing the current state information with the initial state information, and further obtains the judgment result for generating an execution instruction.

[0014] The second technical problem to be solved by the present invention is to provide a hardware adaptive intelligent control method, which uses the above-mentioned hardware adaptive intelligent control system. When initializing the intelligent control system, the initial state information of the hardware input circuit is extracted through the hardware circuit information extraction function family at the initial state of the hardware input circuit; during the operation of the hardware input circuit, the analysis and judgment function family obtains the current state information of the hardware input circuit, compares the current state information with the initial state information, and determines whether the working state of the hardware input circuit has changed; when the working state of the hardware input circuit changes, according to the change state of the hardware input circuit, the control instruction generation function family generates corresponding execution instructions and transmits the execution instructions to the hardware output circuit or the software system receiving the instructions, so that the hardware output circuit or the software system receiving the instructions generates execution actions as required.

[0015] The third technical problem to be solved by the present invention is to provide an intelligent key, which uses the above-mentioned hardware adaptive intelligent control system. The hardware input circuit is a key circuit connected to the key. The hardware circuit information extraction function family extracts the initial state information of the key circuit in the initial state of the key; the analysis and judgment function family obtains the current state information of the key circuit, compares the current state information with the initial state information to determine whether the key is pressed; the control instruction generation function family generates an execution instruction according to the judgment result of whether the key is pressed obtained by the analysis and judgment function family.

[0016] The fourth technical problem to be solved by the present invention is to provide an intelligent keyboard, which has a plurality of the intelligent keys, and further includes an identification function family for defining or naming each intelligent key according to the distribution of the intelligent keys, and the definition or naming of the intelligent key is associated with its recognition information; when the keyboard is initialized, the hardware circuit information extraction function family extracts the initial state information of each intelligent key and associates it with the recognition information of the intelligent key; the analysis and judgment function family cyclically obtains the current state information of each intelligent key during the operation of the keyboard and judges whether the key is pressed by comparing with the initial state information; the control instruction generation function family generates an execution instruction based on the judgment result and the definition or naming of the intelligent key.

[0017] The beneficial effect of the present invention is that the intelligent control system judges whether the state of the hardware input circuit has changed by comparing the current state information of the hardware input circuit with the initial state information, and generates a corresponding execution instruction according to the change situation. This method does not need to pay attention to the structure of the hardware input circuit itself, but only needs to pay attention to the change situation of the signals transmitted by it. Therefore, the setting of the relevant control program is simpler, and it has general adaptability to the hardware input circuit that controls the subsequent circuit or program depending on several input states.

[0025] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments. The specific contents listed in the following embodiments are not limited to the technical features necessary for the technical problems to be solved by the technical solutions recorded in the claims. At the same time, the listed embodiments are only a part of the present invention, rather than all embodiments.

[0026] The hardware adaptive intelligent control system of the present invention can be adapted to a variety of application systems. The program of the intelligent control system can be set in the core function hardware of the application system as shown in Figure 1 , and interact with the hardware input circuit and the hardware output circuit (or software that accepts instructions) of the application system. The solid lines in the figure represent the signal transmission of the hardware circuit, and the dashed lines represent the interaction of relevant data and instructions of the intelligent control system. As shown in Figure 2 , the intelligent control system includes a hardware circuit information extraction function family, an analysis and judgment function family, and a control instruction generation function family. The hardware circuit information extraction function family, the analysis and judgment function family, and the control instruction generation function family are all composed of function codes. All function codes are included in the function code library of the intelligent control system, and the functions in the function code library share the same data set.

[0027] The hardware circuit information extraction function family is a group of functions and their codes that can extract the effective information of the hardware input circuit, used to extract effective information such as the initial state information from the hardware input circuit, and save the information in the shared data set or transfer it to the analysis and judgment function family. The information extracted by the hardware circuit information extraction function family is only the input information transmitted by the hardware input circuit, such as the information transmitted to the core function hardware interface of the application system, without considering the internal circuit composition and working parameters of the hardware input circuit. The initial state information extracted by the hardware circuit information extraction function family is associated with the identification information of the hardware input circuit. The identification information is the relevant information used to identify the hardware input circuit or the input unit therein, such as the hardware circuit interface number of the hardware input circuit. This identification information can be stored in the shared data set during system setup to distinguish which hardware input circuit or which input unit of the hardware input circuit the extracted information belongs to.

[0028] The analysis and judgment function family is a group of functions and their codes that can read traditional data from the shared data set or obtain the current state information from the hardware input circuit and make analysis and judgment. The analysis and judgment function family obtains the current state information of the hardware input circuit, and compares and judges the current state information with the initial state information. The judgment result is saved in the shared data set or transferred to the control instruction generation function family. When obtaining the current state information of the hardware input circuit, the analysis and judgment function family can integrate some functions of the hardware circuit information extraction function family to simplify the program setup.

[0029] The analysis and judgment function family determines the working state of the hardware input circuit mainly based on whether the current state information has changed compared with the initial state information or what kind of changes have occurred. It only considers whether there are changes or the way of changes, and does not need to care about the specific meaning of the current state information. The working state of the hardware input circuit includes the initial state when there is no input event and one or more change states when an input event occurs. Taking a button with two working states as an example, it includes the initial state when it is not pressed (no input event) and a change state when it is pressed (an input event is sent). When the hardware input circuit (i.e., the button circuit) is initialized, the hardware circuit information extraction function family extracts the initial state information of the hardware input circuit (i.e., the information when the button is not pressed). During the operation of the hardware input circuit, the analysis and judgment function family obtains the current state information, and determines the working state of the button by comparing whether the current state information is the same as the initial state information. For example, if the current state information is the same as the initial state information, it is judged that the button is in the state of not being pressed. If the current state information is different from the initial state information, it is judged that the button is in the changed state of being pressed. The analysis and judgment function family judges whether the working state of the hardware input circuit has changed by comparing the current state information with the initial state information, and then obtains the judgment result for generating the execution instruction. Similar to the button, components such as switch sensors also include two working states, such as the initial state of not detecting a relevant signal and the change state of detecting a signal, and the above intelligent control system is also applicable. For multi-state components, such as a hardware input circuit with 3 working states, it usually includes an intermediate state and two change states deviating from the intermediate state in different ways. In the initialization stage, the hardware circuit information extraction function family extracts the initial state information at the intermediate state. In the operation stage, by comparing the current state information with the initial state information, it is determined whether the state has changed and the way of change, and then the judgment result for generating the execution instruction is obtained. Hardware input circuits with more change states are similar, and can be adapted by setting the number of judgment conditions in the analysis and judgment function family.

[0030] The described control instruction generation function family is a group of functions and their codes that can read the judgment results generated by the analysis and judgment function family from the shared data set or directly receive the judgment results. The control instruction generation function family generates execution instructions according to the judgment results of the analysis and judgment function family, and transfers the execution instructions to the hardware output circuit or the software system receiving the instructions, so that the hardware output circuit or the software system receiving the instructions generates execution actions as required. According to needs, the control instruction generation function family can be integrated with the analysis and judgment function family. For example, when the execution instruction is relatively simple, a function for outputting the execution instruction can be integrated after the analysis and judgment function family.

[0031] The method for the present invention to use a hardware adaptive intelligent control system to control a relevant application system is as follows: in the initial stage when the relevant application system starts to run, initialize the intelligent control system, and extract the initial state information of the hardware input circuit through the hardware circuit information extraction function family at the initial state of the hardware input circuit; during the operation of the hardware input circuit, obtain the current state information of the hardware input circuit by the analysis and judgment function family, and compare the current state information with the initial state information to judge whether the working state of the hardware input circuit has changed according to the change situation of the obtained state information. When the working state of the hardware input circuit changes, according to the changed state of the hardware input circuit, the control instruction generation function family generates corresponding execution instructions, and transmits the execution instructions to the hardware output circuit or the software system receiving the instructions, so that the hardware output circuit or the software system receiving the instructions generates execution actions as required.

[0032] Taking an intelligent button as an example, the hardware input circuit is the button circuit connected to the button. The hardware circuit information extraction function family extracts the initial state information of the button circuit at the initial state of the button. The analysis and judgment function family obtains the current state information of the button circuit, and compares the current state information with the initial state information to judge whether the button is pressed. The control instruction generation function family outputs corresponding execution instructions according to the state of whether the button is pressed, such as outputting a control signal, or an output content defined when the system is preset, such as the name of the case, etc. The initialization operation when the hardware adaptive intelligent control system is preset can be implemented through the set initialization function. Set the pins receiving the button circuit signal, relevant information of the button, etc. through initialization, such as the debounce time of the button, the name of the button, etc. The set information is stored in the shared data set.

[0033] The relevant program code examples are as follows: Among them, inputclass_button is an initialization function. The _debouncetime field in the dataset stores the set parameter dtime, and the _inputpin stores the signal value of the hardware input circuit interface inputpin. init() is a function in the function family for extracting hardware circuit information, which is used to read _inputpin and assign it as the initial state information to _tempinput in the dataset. onPressed() is a function in the function family for analysis and judgment. During operation, it reads _inputpin and stores it as the current state information in _tempoutput of the dataset, and then compares _tempoutput with _tempinput. The function family for extracting hardware circuit information only extracts the initial state information in the initial state, while the function family for analysis and judgment continuously loops and repeats to obtain the current state information at a predetermined sampling frequency to determine in real time whether the input signal has changed. In this embodiment, the function family for analysis and judgment incorporates the relevant functions of the function family for extracting hardware circuit information to extract the input state information. The function family for generating control instructions is integrated with the function family for analysis and judgment. According to the comparison result of _tempoutput and _tempinput, if they are the same, it outputs true; if they are different, it stores false.

[0034] Figure 4 and Figure 5 The figure shows an application example of the hardware adaptive intelligent control system in an intelligent button. In the figure, D1 is an LED lamp, and B1 is a button (or push button), which together with resistors R1, R2, and a power supply form an application circuit for controlling the lamp to light up when the button is pressed. The program of the intelligent control system is set in the single-chip microcomputer U1. The relevant setting parameters during the initialization setting of the intelligent control system are stored in the shared dataset. For example, the pin number of the single-chip microcomputer connected to the button is set to 2, and the pin number for the single-chip microcomputer to output the execution instruction is set to 6. Figure 4 and Figure 5 The difference lies in the different positions of the button B1. When the button is pressed, the signals input to the single-chip microcomputer are different. Figure 4 When the button is pressed in [reference 1], a high level is input to pin 2 of the single-chip microcomputer, while Figure 5 when the button is pressed in [reference 2], a low level is input to pin 2 of the single-chip microcomputer. Although the connection methods of these two circuits are different and the level signals input to the single-chip microcomputer pins are different, the intelligent control systems used are the same. The hardware adaptive intelligent control system and its program code in the above example can be adopted. When it is determined that the current state information is different from the initial state information, it outputs true to control the LED lamp to light up.

[0035] Figure 6 and Figure 7The following is an application example of the hardware adaptive intelligent control system in a switching sensor. In the figure, D1 is an LED lamp, and LDR1 is a switching sensor for detecting sound. It is usually in the off state and conducts when detecting sound above a certain amplitude. It cooperates with resistors R1, R2, and a power supply to form an application circuit for controlling the lamp to turn on based on sound. Although the circuit components in this application example are different from those in Figure 4 and Figure 5 shown, the above-mentioned hardware adaptive intelligent control system and its program code can still be adopted. In the application example of the intelligent button, the judgment result of the function onPressed() indicates whether the button is pressed, while in this application example, it indicates whether the sensor conducts. When it is judged that the current state information is different from the initial state information, it is judged that the sensor receives a sound signal and conducts, and outputs true to control the LED lamp to light up.

[0036] In the above program code example, the parameters dtime, the function onPressed(), the output true, etc. are just names set for easy understanding and are not limitations on specific meanings. They can be any names as long as the necessary setting parameters are set according to the specific application example, and the corresponding execution instructions are output based on the comparison result of the current state information and the initial state information. The execution instructions can be to output one or more level signals or information output to the relevant software that receives the instructions.

[0037] Figure 3The following is an application example of the hardware adaptive intelligent control system in an intelligent keyboard. The intelligent keyboard consists of 12 keys, forming a 3×4 array, including rows A - D and columns 1 - 3. The circuit of each key is connected to the corresponding pin of the single - chip microcomputer U1. For example, key 1 is connected to pins 4 and 5 of the single - chip microcomputer U1. Each key adopts the above - mentioned intelligent key. In this application example, there is also a display LCD2 for displaying the input content of the intelligent keyboard. Since it is necessary to display input numbers or characters, this application example also includes an identification function family for defining or naming each intelligent key. When the intelligent keyboard is initialized, the input pins and key names of each intelligent key are set according to the distribution of the keys in the intelligent keyboard. Among them, the input pins are used as identification information to distinguish different keys, and the key names are associated with the input pins of the keys. This application example can be regarded as a collection of multiple above - mentioned intelligent key application examples. The system operation process can be regarded as a process of sequentially running each of the set multiple intelligent keys one by one. The process of each key obtaining initial state information, current state information, and comparison and judgment can all adopt the above - mentioned hardware adaptive intelligent control system and its program code. When the keyboard is initialized, the hardware circuit information extraction function family is called to extract the initial state information of each intelligent key one by one and associate it with the identification information of the intelligent key. During the operation of the keyboard, the analysis and judgment function family is called to cyclically obtain the current state information of each intelligent key, and it is judged whether the key is pressed by comparing with the initial state information; the control instruction generation function family generates an execution instruction according to the judgment result and the definition or naming of the intelligent key. In this application example, the control instruction generation function family outputs the execution instruction true as in the previous application example. This execution instruction true can be output to the software that accepts the instruction. For example, a function getname extracts the key name according to the pin to which the key is connected and outputs a corresponding signal to the display LCD2, so that the corresponding number or character of the key can be displayed on the display LCD2. The control of this intelligent keyboard is different from the usual keyboard control method and does not need to pay attention to the internal circuit structure and related parameters of the keyboard itself. For example, when a usual keyboard detects whether a key is pressed, it needs to scan the keys of the keyboard. Depending on different keyboard circuits, it may use high - level scanning or low - level scanning. However, by using the hardware adaptive intelligent control system of the present invention, it only needs to read the signal input from the keyboard circuit to the pins of the single - chip microcomputer and judge whether the signal changes during the operation of the keyboard. When the signal changes, the corresponding execution instruction is output, and there is no need to scan the keyboard circuit anymore, so there is no need to pay attention to the keyboard circuit structure, the universality is better, and the program setting is simpler.

[0038] According to the above application examples, the hardware adaptive intelligent control system can be regarded as a basic unit. One basic unit can correspondingly control a relatively simple hardware input circuit, and multiple such basic units can be combined into a more complex system to correspondingly control a more complex hardware input circuit. For different application systems, different initial parameters and required execution instructions can be set as needed.

[0039] The above description of the specific implementation manners is only used to help understand the technical concept and its core idea of the present invention. Although specific preferred embodiments are used in this article to describe and illustrate the technical solutions, it should not be construed as a limitation to the present invention itself. Those skilled in the art can make various changes in its form and details without departing from the technical concept of the present invention. These easily conceivable changes or substitutions should all be covered within the protection scope of the present invention.
