[0024] The present application will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present application can be combined with each other.

[0025] To address the technical problems of existing PLC systems failing to meet complex industrial control requirements, the limited ability of PLC CPU modules to process complex data, and the potential for excessive CPU resource consumption leading to a decline in overall PLC reliability and stability, this embodiment provides a PLC system configuration method. This method, by adding intelligent modules, avoids complex data analysis by the CPU module, thereby ensuring the overall reliability and stability of the PLC system. Figure 1 As shown, the above method includes the following steps:

[0026] Step 101: Based on the received download mode, generate target configuration information for configuring the intelligent module connected to the CPU module.

[0027] In the embodiment, the PLC system comprises a CPU module, a power module, a high-speed backplane and at least one intelligent module, and can further comprise a plurality of I / O modules, a camera device connected to the intelligent module by using a video line, a sensor connected to the intelligent module by using an external bus and an external device of the intelligent module. As shown in Figure 2 The CPU module is a master device of the PLC system, used to execute an application layer program, issue instructions and data to other modules by means of high-speed backplane communication, read feedback data of other modules, and realize control of the entire PLC system; the high-speed backplane constitutes a physical connection for communication between the CPU module and other modules, and realizes data transmission at a relatively fast speed.

[0028] In step 102, when the download mode is the first download mode, the CPU module completes the configuration operation of the PLC system by downloading after verifying the configuration information stored in the intelligent module and the array data corresponding to the configuration information according to the target configuration information.

[0029] In step 103, when the download mode is the second download mode, the CPU module completes the configuration operation of the PLC system by downloading after verifying the data format of the configuration information stored in the intelligent module according to the target configuration information.

[0030] In the embodiment, the intelligent module selects different download modes according to different data analysis requirements of the PLC system in the PLC system configuration process, and different download modes correspond to different target configuration information. The download modes include a CPU module download mode and an external bus download mode. When an executable code such as an algorithm program (mathematical algorithm, self-defined algorithm), a machine vision model or an artificial intelligence model is compiled and generated, the executable code is downloaded to the intelligent module and saved to the FLASH inside the intelligent module. The executable code of the intelligent module can be generated by a PLC programming software and downloaded by the CPU module and the high-speed backplane interface, or generated by a special programming software and downloaded by the external bus.

[0031] For the embodiment, the target configuration information for configuring the intelligent module connected with the CPU module can be generated according to the received download mode according to the above scheme; when the download mode is the first download mode, the CPU module checks the configuration information stored in the intelligent module and the array data corresponding to the configuration information according to the target configuration information, and then completes the configuration operation of the PLC system through downloading; when the download mode is the second download mode, the CPU module checks the data format of the configuration information stored in the intelligent module according to the target configuration information, and then completes the configuration operation of the PLC system through downloading. Compared with the prior art PLC system which cannot meet the complex industrial control requirements and the technical scheme in which the CPU module of the PLC has weak ability to process complex data, the embodiment adds an intelligent module in the PLC system, the CPU module is mainly used for logical control and verification of the intelligent module, and the CPU module is released from complex mathematical operation, so as to enhance the reliability and stability of the PLC system as a whole.

[0032] Further, as a refinement and expansion of the above embodiment, in order to completely describe the specific implementation process of the embodiment, another configuration method of a PLC system is provided, the embodiment can be applied in different industrial systems to realize intelligent configuration operation of the PLC system, the embodiment can release the pressure of complex mathematical operation of the CPU module according to different download modes by adding an intelligent module in the PLC system, so as to enhance the reliability and stability of the PLC system as a whole. As shown in Figure 3 The method comprises the following steps:

[0033] Step 301, configuration starts.

[0034] Step 302, set mode, parameter and other configuration information.

[0035] In the implementation, step 302 is consistent with step 101, the target configuration information for configuring the intelligent module connected with the CPU module is generated according to the received download mode, that is, the mode, parameter and other configuration information required by the intelligent module during PLC system configuration, and the configuration steps of the intelligent module include: downloading the first executable code of the intelligent module generated by compiling to the intelligent module; and downloading the second executable code corresponding to the data analysis requirement of the PLC system to the intelligent module.

[0036] In the implementation, as Figure 4As shown, the intelligent module is a core module for fast data processing and complex operation in the PLC system, and internally includes a control and calculation core (central processor), a running memory (RAM), a FLASH memory (ROM), a high-speed backplane interface circuit and a physical interface (high-speed backplane interface), a video interface circuit and a physical interface (video input interface), an external bus interface circuit and a physical interface (external bus interface), and a power supply circuit for powering all the above components.

[0037] The control and calculation core of the intelligent module has strong computing power, high floating-point operation capability and parallel computing capability, and can be used to carry a local artificial intelligence model. The running memory of the intelligent module has a large memory capacity, which can meet the memory requirements of complex mathematical algorithms, thereby releasing the operation pressure of the CPU module. The FLASH of the intelligent module has a large storage capacity, which can be used to store configuration data, artificial intelligence model data and executable code of the intelligent module, and the like. The intelligent module has a high-speed backplane communication capability matching the CPU module to realize data interaction with the CPU module. The intelligent module has a video input interface, which can be connected with an external camera device based on a video line to obtain video data and image data from the camera device. The intelligent module has an external bus interface, which can communicate with external devices of the intelligent module, receive control instructions of the external devices of the intelligent module and feedback execution results (here, the sensors and camera devices of the external devices are different), thereby meeting the application function requirements of the PLC system. In addition, the external bus interface can also be connected with a special sensor to directly obtain sensor data.

[0038] To illustrate the specific implementation of step 302, as a preferred embodiment, step 302 includes configuring a mathematical algorithm or a custom algorithm corresponding to a data analysis requirement of the PLC system in the intelligent module according to the data analysis requirement, wherein the data analysis requirement of the PLC system includes a first data analysis requirement of a CPU module connected with the intelligent module and a second data analysis requirement of an external device connected with the intelligent module.

[0039] In implementation, the intelligent module has a plurality of preset analysis modes and a custom analysis mode in function, and the preset analysis modes include but are not limited to a data fast analysis mode, an image intelligent analysis mode and a running state evaluation mode. The custom analysis mode is that the intelligent module is programmed by an external device of the intelligent module or during PLC programming, thereby being capable of flexibly configuring the function of the intelligent module. In the custom mode, the intelligent module can also use script programming to call preset functions in the programming software of the upper computer. It should be noted that the underlying communication between the intelligent module and the CPU module adopts a fixed format, and the intelligent module uses the same function code and data format in all modes, which is not specifically limited here.

[0040] When it is determined that the data analysis requirement of the current PLC system includes the first data analysis requirement of the CPU module connected with the intelligent module or the second data analysis requirement of the external device connected with the intelligent module, a preset mathematical algorithm (such as FFT, wavelet analysis, etc.) or a user-defined algorithm corresponding to the data analysis requirement is configured in the corresponding intelligent module during the configuration of the PLC system, the data analysis requirement corresponds to a data rapid analysis mode, and accordingly, in the data rapid analysis mode, the intelligent module processes and analyzes the sensor data from the CPU module or from the directly connected sensor by calling the configured mathematical algorithm or user-defined algorithm, thereby releasing the pressure of the CPU module and quickly completing the processing and analysis of the data by the computing power of the intelligent module.

[0041] To illustrate the specific implementation of step 302, as a preferred embodiment, step 302 includes: if the data analysis requirement of the PLC system includes an image analysis requirement, a machine vision model is configured in the intelligent module.

[0042] Accordingly, after the step of completing the configuration operation of the PLC system by downloading, the step further includes: receiving video data based on the video input interface of the intelligent module, analyzing the video features by using the machine vision model configured in the intelligent module, and sending the video features to the CPU module via the high-speed backplane interface. In implementation, when it is determined that the data analysis requirement of the current PLC system includes an image analysis requirement, the intelligent module is equipped with a machine vision model, and during the operation of the PLC system, the image analysis requirement corresponds to an image intelligent analysis mode, that is, in the image intelligent analysis mode, the video data from the camera device is received by the video input interface, and the analysis of the video data is completed by the machine vision model. The machine vision model is a trained machine vision model, for example, trained based on the morphological images of different components and selected and configured by the user, that is, the intelligent module analyzes the input video data by using the already trained machine vision model, and after obtaining the video features, the video features are returned to the CPU module via the high-speed backplane interface, so that the CPU module makes a decision.

[0043] To illustrate the specific implementation of step 302, as a preferred embodiment, step 302 includes: if the data analysis requirement of the PLC system includes a running state analysis requirement, an initialized artificial intelligence model is configured in the intelligent module.

[0044] Correspondingly, the step of completing the configuration operation of the PLC system by the downloading is followed by: when the controlled device is running, the CPU module controls the intelligent module to train the initialized artificial intelligence model to obtain a trained artificial intelligence model; and the trained artificial intelligence model is used to analyze whether the running state of the controlled device is abnormal, and a running state result is sent to the CPU module via the high-speed backboard interface.

[0045] In implementation, when it is determined that the data analysis requirement of the current PLC system includes the running state analysis requirement, an artificial intelligence model is loaded in the corresponding intelligent module during the configuration of the PLC system, the running state analysis requirement corresponds to a running state evaluation mode, in the running state evaluation mode, sensor data from the CPU module or from a directly connected sensor is received, the CPU module controls the intelligent module to complete the training of the artificial intelligence model when the controlled industrial system (for example, a sewage treatment system, an air conditioning system, etc.) is running, the input data is analyzed after the training of the artificial intelligence model is completed, so as to monitor the abnormal running state in the running of the controlled industrial system, and the monitored running state result is fed back to the CPU module via the high-speed backboard interface.

[0046] Step 303: whether to use the external bus downloading mode. If the external bus downloading mode is used, steps 3041-3061 are executed, and if the external bus downloading mode is not used, steps 3042-3062 are executed.

[0047] Step 3041: verifying the configuration information and the data content.

[0048] Step 3051: verifying whether the verification is successful.

[0049] Step 3061: writing the target configuration information and the data content.

[0050] In implementation, when it is determined that the external bus downloading mode is not used, the first downloading mode is the CPU module downloading mode, the target configuration information and array data corresponding to the target configuration information are obtained, it is judged whether the configuration information stored in the intelligent module and the array data corresponding to the configuration information are consistent with the target configuration information and the array data corresponding to the target configuration information, if the two are consistent, the verification is successful, and the configuration operation of the PLC system is completed by the downloading; and if the two are not consistent, the verification fails, the target configuration information and the array data corresponding to the target configuration information are directly written, and the configuration operation of the PLC system is completed by the downloading.

[0051] Step 3042: verifying the data format of the external bus downloading.

[0052] Step 3052: verifying whether the verification is successful.

[0053] Step 3062, report configuration error.

[0054] In the implementation, when it is determined to use the external bus download mode, the second download mode is the external bus download mode, the preset data format corresponding to the target configuration information is obtained, and it is judged whether the data format of the configuration information stored in the smart module is consistent with the preset data format; the data format is byte format; if they are consistent, the verification is successful, and the configuration operation of the PLC system is completed through the download; if they are not consistent, the verification fails, error information is generated, and the configuration operation of the PLC system is completed through the download after the re-verification is successful.

[0055] According to the actual application scene requirement, when the PLC system configuration of the smart module is performed, the target configuration information such as the selected mode, the corresponding parameter, and the CPU module download mode or the external bus download mode is selected, and the smart module is configured by the CPU module. Specifically, when the CPU module download mode is selected, the CPU module verifies whether the configuration information stored in the smart module and the array data format thereof are consistent with the target configuration information and the array data format thereof, for example, whether the data contents of the corresponding positions in the array data of the two are consistent (both are 1 or 0), if they are not consistent, the target configuration information and the corresponding array data are written into the smart module, if they are consistent, no change is needed, and step 307 is executed; when the external bus download mode is selected, the downloaded data content has a fixed data format, and when the smart module is configured, the CPU module verifies whether the data format stored in the smart module conforms to the preset data format in the target configuration information, if it does not conform to the preset data format, for example, the data formats stored in the corresponding bytes of the two are different (for example, the same byte is a temperature parameter and a deformation parameter), error information is generated, step 307 is executed, and the configuration operation of the PLC system is completed through the download after the re-verification is successful.

[0056] Step 307, configuration end.

[0057] By applying the technical scheme of the embodiment, target configuration information for configuring the intelligent module connected with the CPU module is generated according to the received download mode; when the download mode is the first download mode, the CPU module verifies the configuration information stored by the intelligent module and the array data corresponding to the configuration information according to the target configuration information, and then completes the configuration operation of the PLC system through downloading; when the download mode is the second download mode, the CPU module verifies the data format of the configuration information stored by the intelligent module according to the target configuration information, and then completes the configuration operation of the PLC system through downloading. Compared with the prior art PLC system which cannot meet the complex industrial control requirements and the CPU module of the PLC has weak ability to process complex data, the PLC system is more flexible in building mode and programming mode than the traditional PLC system, and has higher support for complex mathematical operations, thereby meeting more complex industrial scenarios. Accordingly, the CPU module is freed from the existing complex mathematical operations, and is mainly used for logical control and verification of the intelligent module, thereby avoiding the technical problem that the overall reliability and stability of the existing PLC system are poor due to excessive data processing of the CPU module.

[0065] The third configuration unit 513 is configured to configure a machine vision model in the intelligent module if the data analysis requirement of the PLC system includes an image analysis requirement; and correspondingly, after the step of completing the configuration operation of the PLC system by downloading, the method further includes receiving video data based on a video input interface of the intelligent module, analyzing the video features by using the configured machine vision model in the intelligent module, and sending the video features to the CPU module via a high-speed backplane interface.

[0069] In a specific application scenario, the second lower module 53 comprises a second checking unit 531.

[0070] The second checking unit 531 is configured to acquire a preset data format corresponding to the target configuration information in an external bus lower mode, to determine whether the data format of the configuration information stored in the intelligent module is consistent with the preset data format, to determine that the checking is successful if the two are consistent, to complete the configuration operation of the PLC system through the lower mode, to generate an error information if the two are inconsistent, and to complete the configuration operation of the PLC system through the lower mode after the checking is successful again.
