[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0026] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0027] In order to solve the technical problems of difficult PLC management and low adjustment efficiency in the prior art, the present application provides a PLC adjustment method that can achieve the effect of improving the adjustment efficiency of the PLC.

[0028] Figure 1 A flow chart of a PLC adjustment method provided in an embodiment of the present application, such as Figure 1 As shown, including:

[0029] S102, receiving an adjustment instruction for adjusting a target PLC, wherein the target PLC is used to control intelligent devices in a target area;

[0030] S102, parsing the adjustment instruction to obtain the type and adjustment strategy of the target PLC;

[0031] S106, when the target PLC is a virtual PLC, the target PLC on the server is adjusted according to the adjustment strategy; when the target PLC is a physical PLC, the adjustment strategy is transmitted to the target PLC through the server, so that the target PLC is adjusted according to the adjustment strategy.

[0032] The present application can configure a digital base, which includes a programmable logic controller (PLC), and the PLC can control intelligent devices. For example, for a building, the building includes a variety of intelligent devices, such as central air conditioning, corridor lights, elevators, alarms, etc. And a variety of intelligent devices must be controlled by PLC. For example, the PLC used to control the light can control the light and dark time period of the light. Most of the existing PLCs are physical PLCs, and if the control logic of the PLC is to be adjusted, it is necessary to go to the location of the PLC and insert a physical line to import the control logic of the PLC into the PLC device, such as allowing the PLC device to control the light and dark time period of the light according to the imported control logic. However, this method is laborious and cumbersome to adjust the PLC. In this embodiment, by configuring the digital base, the digital base can be located on the server, so that both the physical PLC and the virtual PLC can be connected to the digital base, so that all PLCs can be managed and controlled through a unified platform. For example, if the PLCs of all smart devices in a community are integrated into the digital base, the property management can be given permissions to adjust any PLC on the digital base. The PLCs will control the smart devices in the community according to the adjusted strategy.

[0033] In this embodiment, the digital base can be located on the server, but because the virtual PLC is configured on the server, the physical PLC is a physical device and will not be located on the server. Therefore, the physical PLC can be communicated through the server, so that the physical PLC and the virtual PLC are integrated into a platform through the server as a digital base. If the user wants to adjust any PLC on the digital base, whether it is a physical PLC or a virtual PLC, he can access the server through the client and initiate adjustment instructions through the client to adjust the physical PLC or virtual PLC. The client can be a mobile terminal, a physical host, a cloud host, a virtual machine, a mini-program, an application on the terminal, etc. In other words, the user does not limit the way to access the server.

[0034] When the user is controlling the PLC, the front-end page can be displayed on the client. The user can use the front-end page to select the PLC to be controlled and what adjustments to make. After the user has configured the PLC to be controlled and what adjustments to make through the front-end page, an adjustment command can be issued. The adjustment command is used to adjust the target PLC. The target PLC can be one or more.

[0035] After obtaining the adjustment instruction, the server can parse the adjustment instruction. The purpose of the analysis is to check which target PLCs the user wants to control and the adjustment strategy for each target PLC. The adjustment strategy is what adjustments to make. After parsing the adjustment instruction, the type of the target PLC to be adjusted is obtained. Since the server includes virtual PLCs and physical PLCs, the strategy is different depending on the type of the target PLC to be adjusted.

[0036] For virtual PLC, virtual PLC is a microservice set on the server, and the functions of virtual PLC are realized through microservice. For example, a microservice for controlling an elevator is set on the server as the virtual PLC of the elevator. For physical PLC, the physical PLC can be configured near the elevator or in the community to control the elevator. A connection is established between the server and the physical PLC.

[0037] When the adjustment instruction is parsed and the target PLC that the user wants to adjust is determined, if the target PLC is a virtual PLC, the virtual PLC on the server can be adjusted directly. When adjusting the virtual PLC, the control logic in the microservice of the virtual PLC can be adjusted and updated to the new control logic. If the adjustment is made to the physical PLC, the server can send the adjustment strategy to the physical PLC to update the control logic in the physical PLC.

[0038] For example, Figure 2 The figure shows a data interaction diagram. The server contains a record table of the physical PLC and is also configured with a virtual PLC. The record table of the physical PLC corresponds to the physical PLC. The physical PLC and the virtual PLC constitute the digital base. The client interacts with the server to adjust the physical PLC or virtual PLC of the digital base.

[0039] The method provided by the embodiment of the present application receives an adjustment instruction for adjusting a target PLC, wherein the target PLC is used to control intelligent devices in a target area; parses the adjustment instruction to obtain the type and adjustment strategy of the target PLC; when the target PLC is a virtual PLC, adjusts the target PLC on the server according to the adjustment strategy; when the target PLC is a physical PLC, transmits the adjustment strategy to the target PLC through the server to adjust the target PLC according to the adjustment strategy, so that the server can be used to provide microservices of the virtual PLC, and the physical PLC can be connected through the server, so that a digital base can be built on the server to carry the PLC, and the PLC can be easily adjusted.

[0040] In this embodiment, when parsing the adjustment instruction, an optional method is as follows: Figure 3 As shown, the parsing process can be:

[0041] S302, parsing the adjustment instruction and obtaining adjustment information;

[0042] S304, when the adjustment information includes the device unique identifier, device model, performance indicators and adjustment strategy, determine that the target PLC is a virtual PLC and obtain the adjustment strategy; when the adjustment information only includes the unique identifier and adjustment strategy, determine that the target PLC is a physical PLC and obtain the adjustment strategy.

[0043] The core purpose of parsing the adjustment instruction is to obtain the adjustment information in the adjustment instruction. The adjustment information may include the device unique identifier, device model, performance indicators and adjustment strategy, or may not include performance indicators and device model. Because the corresponding device can be found through the device unique identifier. The adjustment strategy is the strategy for adjusting the only target PLC found. The device model and performance indicators are the model and performance indicators of the virtual PLC to be created on the server when the target PLC corresponding to the device unique identifier cannot be found.

[0044] In this embodiment, the amount of content included in the adjustment information in the adjustment instruction can determine whether the user wants to adjust the virtual PLC or the physical PLC. In another embodiment, the user can provide the device unique identifier, device model, performance index and adjustment strategy when creating a virtual PLC, and can also only provide the device unique identifier and adjustment strategy when adjusting the virtual PLC. In this case, the device unique identifier can be used to check whether the PLC to be adjusted is a virtual PLC or a physical PLC.

[0045] When the user decides to adjust a target PLC, an adjustment command can be initiated. Regardless of whether the PLC to be adjusted is a physical PLC or a virtual PLC, a virtual PLC can be created on the server according to the default device model and performance indicators when the target PLC to be adjusted cannot be found.

[0046] In this embodiment, the adjustment strategies for the virtual PLC and the physical PLC are different. As an implementation method, when the target PLC is a virtual PLC, Figure 4 As shown, adjusting the target PLC on the server according to the adjustment strategy includes:

[0047] S402, searching for a target PLC on the server;

[0048] S404, when the target PLC is found, the target PLC is adjusted; when the target PLC is not found, a microservice of the target PLC is created to simulate the target PLC.

[0049] In this embodiment, if the target PLC is a virtual PLC, the target PLC can be searched on the server. If the target PLC can be found, it can be adjusted directly. Since the target PLC is a virtual PLC, on the server, the control logic can be directly modified to obtain the adjusted target PLC. If the target PLC corresponding to the device unique identifier cannot be found on the server, it means that the target PLC corresponding to the device unique identifier is not stored on the server at all. At this time, either the user's device unique identifier is entered incorrectly, or the server does not have the target PLC that the user thinks should be there. Therefore, the corresponding target PLC can be generated on the server according to the adjustment instructions provided by the user, and the generated target PLC is a virtual PLC.

[0050] When generating a target PLC, if the user provides a device model and performance indicators, the target PLC can be generated according to the device model and performance indicators provided by the user. If the user does not provide a device model and performance indicators, the default device model and performance indicators can be used to create the target PLC.

[0051] In this embodiment, when searching for the target PLC on the server, the target PLC can be searched according to the device unique identifier in the adjustment instruction; a unique target PLC can be found according to the device unique identifier in the adjustment instruction. If the corresponding target PLC cannot be found on the server, it means that there is no corresponding PLC on the server, and the target PLC can be created according to the above-mentioned process. If a PLC matching the device unique identifier can be found, the model of the PLC found can be compared with the device model in the adjustment instruction to see if it is consistent; the purpose of comparing the model of the PLC found with the device model in the adjustment instruction is that although a unique device can be found through the device unique identifier, it is also necessary to see whether the unique device is consistent with the device model input by the user. If the device model is inconsistent, it means that although there is a virtual PLC corresponding to the device unique identifier on the server, the virtual PLC may not be the PLC of the model the user wants. Therefore, when the model of the PLC found is consistent with the device model, it is determined that the target PLC is found; when the model of the PLC found is inconsistent with the device model or the PLC matching the device unique identifier is not found, it is determined that the target PLC is not found. Therefore, a virtual PLC of the corresponding model can be created according to the user's device model.

[0052] In this case, the same device unique identifier may correspond to multiple virtual PLCs, and different virtual PLCs have different device models. However, in order to make the device unique identifier uniquely correspond to a device, the target PLC can be found according to the user's device unique identifier, but when the device model of the target PLC is different from the device model entered by the user, after creating the device model entered by the user, a device unique identifier is assigned to the device model, and the newly assigned device unique identifier is returned to the user. In this way, each PLC on the server can be marked with a unique identifier.

[0053] In this embodiment, when creating a virtual PLC on a server, in addition to the device model, a performance indicator can also be configured. The performance indicator is the performance of the virtual PLC, such as the size of the processor's L3 cache, the number of cores, the bandwidth size, the memory size, etc. When creating a virtual PLC, the virtual PLC can be created by creating a microservice.

[0054] In this embodiment, the adjustment strategies for the virtual PLC and the physical PLC are different. As an implementation method, when the target PLC is a physical PLC, Figure 5 As shown, transmitting the adjustment strategy to the target PLC through the server includes:

[0055] S502, determining a target PLC in the physical PLC according to the device unique identifier in the adjustment instruction;

[0056] S504, sending the adjustment strategy to the target PLC by calling the communication microservice on the server.

[0057] In this embodiment, since the target PLC is a physical PLC, it cannot be deployed on the server, but is deployed in a physical location, such as an elevator shaft, or a place in a community dedicated to arranging physical controllers. In this case, the correspondence between the physical PLC and the unique device identifier can be configured on the server, and a connection relationship is established with the server for each physical PLC. The connection relationship can be provided by a communication microservice. Then, for the adjustment instruction, after determining the physical PLC according to the unique device identifier, the server can send the adjustment strategy in the adjustment instruction to the physical PLC through the microservice to update the control logic of the physical PLC.

[0058] In this embodiment, whether the target PLC is a virtual PLC or a physical PLC, when adjusting the target PLC, the control logic in the adjustment strategy can be downloaded to the target PLC so that the target PLC runs the downloaded control logic. After the target PLC downloads the control logic and updates its own control logic, the smart device can be controlled according to the updated control logic. If the target PLC is a physical PLC, there are many ways to communicate with the smart device. For example, it can be connected through a physical line or through a network. If connected through a network, network communication can be provided through a communication microservice.

[0059] Figure 6 This is a system diagram of this embodiment. It includes a user interaction terminal, a digital base system (i.e., a system including a physical PLC and a virtual PLC), and a collection of smart devices. The user interaction terminal is an interactive terminal for users to operate and view, including but not limited to computer web pages, clients, mobile applications, applets or web pages, used to view device configuration details, device data display, control, etc. The digital base system provides user services and a collection of functions. It includes the following modules:

[0060] PLC logic control microservice: provides users with services to control the logical operation of virtual PLC devices and manage device logic in a unified manner.

[0061] Message channel: Provides internal and external communication services for the digital base system, through which equipment and logical data are transmitted and received.

[0062] Virtual PLC device: A microservice that is independent of the PLC device entity and is used to run related control logic. It has the same functions as the actual PLC device and can be connected to related control devices for logical control.

[0063] Real PLC device: refers to a physical PLC device that runs related control logic internally and can be independently connected to related devices for logical control.

[0064] The device set refers to different types of terminal devices connected to the system, such as lights, air conditioners, fans, temperature sensors, etc. They are controlled through virtual PLC and physical PLC. A, B, and C represent different types of smart devices.

[0065] Figure 7 The following is a schematic diagram for adjusting the target PLC of the digital base. The user can configure the PLC device remotely in the host computer software and can choose whether to configure a real PLC device or a virtual PLC device. PLC logic control microservice: used for configuration, logic download, and unified management and control of PLC devices. If it is a virtual PLC device, configure the relevant device information, including the device model, performance indicators, and device unique identifier, and then generate an independent microservice in the digital base to simulate a virtual PLC device. If it is a real device, you need to enter the corresponding device information, device unique identifier, and remotely connect to the real PLC device through the message channel (communication microservice). Message channel (communication microservice): used for data communication between PLC devices, access devices, and microservices. Then the user downloads the control logic to be run directly to the corresponding virtual PLC device or real device in the host computer software. For processing large-scale data and complex logic, you can choose a virtual PLC device and adjust the corresponding performance indicators of the virtual PLC to dynamically meet the operation requirements. For devices that need to be connected to the PLC, they are remotely connected to the corresponding devices through the message channel (communication microservice), data is exchanged, and related equipment is monitored through message communication.

[0066] This embodiment also provides a PLC adjustment device, such as Figure 8 As shown, including:

[0067] A receiving module 802 is used to receive an adjustment instruction for adjusting a target PLC, wherein the target PLC is used to control smart devices in a target area;

[0068] The parsing module 804 is used to parse the adjustment instruction and obtain the type and adjustment strategy of the target PLC;

[0069] The adjustment module 806 is used to adjust the target PLC on the server according to the adjustment strategy when the target PLC is a virtual PLC; when the target PLC is a physical PLC, the adjustment strategy is transmitted to the target PLC through the server so as to adjust the target PLC according to the adjustment strategy.

The record table of the physical PLC corresponds to the physical PLC. The physical PLC and the virtual PLC constitute the digital base. The client interacts with the server to adjust the physical PLC or virtual PLC of the digital base.

[0077] The method provided by the embodiment of the present application receives an adjustment instruction for adjusting a target PLC, wherein the target PLC is used to control intelligent devices in a target area; parses the adjustment instruction to obtain the type and adjustment strategy of the target PLC; when the target PLC is a virtual PLC, adjusts the target PLC on the server according to the adjustment strategy; when the target PLC is a physical PLC, transmits the adjustment strategy to the target PLC through the server to adjust the target PLC according to the adjustment strategy, so that the server can be used to provide microservices of the virtual PLC, and the physical PLC can be connected through the server, so that a digital base can be built on the server to carry the PLC, and the PLC can be easily adjusted.

[0078] The present embodiment also provides a digital base, including: a virtual PLC and a physical PLC; the digital base is used to receive adjustment instructions for adjusting a target PLC, wherein the target PLC is used to control intelligent devices in a target area; the adjustment instructions are parsed to obtain the type and adjustment strategy of the target PLC; when the target PLC is a virtual PLC, the target PLC on the server is adjusted according to the adjustment strategy; when the target PLC is a physical PLC, the adjustment strategy is transmitted to the target PLC through the server so that the target PLC is adjusted according to the adjustment strategy.

For physical PLC, the physical PLC can be configured near the elevator or in the community to control the elevator. A connection is established between the server and the physical PLC.

[0084] When the adjustment instruction is parsed and the target PLC that the user wants to adjust is determined, if the target PLC is a virtual PLC, the virtual PLC on the server can be adjusted directly. When adjusting the virtual PLC, the control logic in the microservice of the virtual PLC can be adjusted and updated to the new control logic. If the adjustment is made to the physical PLC, the server can send the adjustment strategy to the physical PLC to update the control logic in the physical PLC.

[0085] For example, Figure 2 The figure shows a data interaction diagram. The server contains a record table of the physical PLC and is also configured with a virtual PLC. The record table of the physical PLC corresponds to the physical PLC. The physical PLC and the virtual PLC constitute the digital base. The client interacts with the server to adjust the physical PLC or virtual PLC of the digital base.

[0086] The method provided by the embodiment of the present application receives an adjustment instruction for adjusting a target PLC, wherein the target PLC is used to control intelligent devices in a target area; parses the adjustment instruction to obtain the type and adjustment strategy of the target PLC; when the target PLC is a virtual PLC, adjusts the target PLC on the server according to the adjustment strategy; when the target PLC is a physical PLC, transmits the adjustment strategy to the target PLC through the server to adjust the target PLC according to the adjustment strategy, so that the server can be used to provide microservices of the virtual PLC, and the physical PLC can be connected through the server, so that a digital base can be built on the server to carry the PLC, and the PLC can be easily adjusted.

[0087] This embodiment also provides a PLC adjustment system, such as Fig. 9 As shown, including:

[0088] Client 902, used to initiate adjustment instructions;

[0089] The server 904 is used to receive an adjustment instruction for adjusting a target PLC, wherein the target PLC is used to control the intelligent devices in the target area; parse the adjustment instruction to obtain the type and adjustment strategy of the target PLC; when the target PLC is a virtual PLC, adjust the target PLC on the server according to the adjustment strategy; when the target PLC is a physical PLC, transmit the adjustment strategy to the target PLC through the server, so as to adjust the target PLC according to the adjustment strategy;

[0090] The intelligent device 906 is used to be controlled by the target PLC to realize the function of the device.

[0091] The present application can configure a digital base, which includes a programmable logic controller (PLC), and the PLC can control intelligent devices. For example, for a building, the building includes a variety of intelligent devices, such as central air conditioning, corridor lights, elevators, alarms, etc. And a variety of intelligent devices must be controlled by PLC. For example, the PLC used to control the light can control the light and dark time period of the light. Most of the existing PLCs are physical PLCs, and if the control logic of the PLC is to be adjusted, it is necessary to go to the location of the PLC and insert a physical line to import the control logic of the PLC into the PLC device, such as allowing the PLC device to control the light and dark time period of the light according to the imported control logic. However, this method is laborious and cumbersome to adjust the PLC. In this embodiment, by configuring the digital base, the digital base can be located on the server, so that both the physical PLC and the virtual PLC can be connected to the digital base, so that all PLCs can be managed and controlled through a unified platform. For example, if the PLCs of all smart devices in a community are integrated into the digital base, the property management can be given permissions to adjust any PLC on the digital base. The PLCs will control the smart devices in the community according to the adjusted strategy.

[0092] In this embodiment, the digital base can be located on the server, but because the virtual PLC is configured on the server, the physical PLC is a physical device and will not be located on the server. Therefore, the physical PLC can be communicated through the server, so that the physical PLC and the virtual PLC are integrated into a platform through the server as a digital base. If the user wants to adjust any PLC on the digital base, whether it is a physical PLC or a virtual PLC, he can access the server through the client and initiate adjustment instructions through the client to adjust the physical PLC or virtual PLC. The client can be a mobile terminal, a physical host, a cloud host, a virtual machine, a mini-program, an application on the terminal, etc. In other words, the user does not limit the way to access the server.

[0093] When the user is controlling the PLC, the front-end page can be displayed on the client. The user can use the front-end page to select the PLC to be controlled and what adjustments to make. After the user has configured the PLC to be controlled and what adjustments to make through the front-end page, an adjustment command can be issued. The adjustment command is used to adjust the target PLC. The target PLC can be one or more.

[0094] After obtaining the adjustment instruction, the server can parse the adjustment instruction. The purpose of the analysis is to check which target PLCs the user wants to control and the adjustment strategy for each target PLC. The adjustment strategy is what adjustments to make. After parsing the adjustment instruction, the type of the target PLC to be adjusted is obtained. Since the server includes virtual PLCs and physical PLCs, the strategy is different depending on the type of the target PLC to be adjusted.

[0095] For virtual PLC, virtual PLC is a microservice set on the server, and the functions of virtual PLC are realized through microservice. For example, a microservice for controlling an elevator is set on the server as the virtual PLC of the elevator. For physical PLC, the physical PLC can be configured near the elevator or in the community to control the elevator. A connection is established between the server and the physical PLC.

[0096] When the adjustment instruction is parsed and the target PLC that the user wants to adjust is determined, if the target PLC is a virtual PLC, the virtual PLC on the server can be adjusted directly. When adjusting the virtual PLC, the control logic in the microservice of the virtual PLC can be adjusted and updated to the new control logic. If the adjustment is made to the physical PLC, the server can send the adjustment strategy to the physical PLC to update the control logic in the physical PLC.

[0097] For example, Figure 2 The figure shows a data interaction diagram. The server contains a record table of the physical PLC and is also configured with a virtual PLC. The record table of the physical PLC corresponds to the physical PLC. The physical PLC and the virtual PLC constitute the digital base. The client interacts with the server to adjust the physical PLC or virtual PLC of the digital base.

[0098] The method provided by the embodiment of the present application receives an adjustment instruction for adjusting a target PLC, wherein the target PLC is used to control intelligent devices in a target area; parses the adjustment instruction to obtain the type and adjustment strategy of the target PLC; when the target PLC is a virtual PLC, adjusts the target PLC on the server according to the adjustment strategy; when the target PLC is a physical PLC, transmits the adjustment strategy to the target PLC through the server to adjust the target PLC according to the adjustment strategy, so that the server can be used to provide microservices of the virtual PLC, and the physical PLC can be connected through the server, so that a digital base can be built on the server to carry the PLC, and the PLC can be easily adjusted.
