Description

Technical Field

[0001] The present invention relates to the technical field of network management, and in particular to a networked intelligent controller. Background Art

[0002] With the acceleration of the process of "digital transformation and intelligent manufacturing" in industry, it will be an inevitable trend for important production equipment and energy-consuming equipment in industrial sites to be connected and interconnected. However, in many industrial sites, there are still many independently operated energy-consuming equipment and energy-saving equipment, and manual offline inspection and operation and maintenance of the above-mentioned important equipment are still required. It is impossible to realize online monitoring of the equipment, let alone precise control of the equipment. There is a lack of effective tools to realize intelligent operation and maintenance and energy-saving control of important equipment, so as to ensure the economical, safe and efficient operation of the equipment and realize the control of the entire life cycle of the equipment.

[0003] A networked intelligent controller is a device that combines intelligent control functions with network communication technology. It is often used for collective control of industrial equipment groups to ensure that each industrial equipment in the industrial equipment group has the conditions for coordinated operation and control, thereby completing the target production task.

[0004] However, during the current use of networked intelligent controllers, since the number of networked intelligent controllers is not unique, each networked intelligent controller has the function of controlling each industrial equipment in the industrial equipment group, resulting in the use of networked intelligent controllers still requiring manual management to achieve controller switching to implement central control of the industrial equipment group and ultimately execute production tasks and related industrial equipment control.

[0005] To this end, we propose a networked intelligent controller. Summary of the invention

[0006] In view of the above-mentioned shortcomings of the prior art, the present invention provides a networked intelligent controller to solve the technical problems raised in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A networked intelligent controller, comprising:

[0009] A construction module is used to upload the network nodes where the industrial equipment control network is located, and to construct the industrial equipment control network topology based on the network nodes where the industrial equipment control network is located; an evaluation module is used to obtain the industrial equipment control network topology, and to evaluate the busyness of the industrial equipment corresponding to each network node in the industrial equipment control network topology based on the operating parameters and the industrial equipment control network topology level; a monitoring module is used to monitor the network status of each industrial equipment; a trigger module is used to set a trigger threshold, obtain the busyness evaluation results of the industrial equipment in the evaluation module based on the operating parameters and the industrial equipment control network topology level and the industrial equipment network status monitoring results in the monitoring module, and trigger the switching operation of the control command source device based on the comparison of the two sets of results with the trigger threshold; a decision module is used to obtain the operation result of the trigger module, and when the operation result of the trigger module is to trigger the switching of the control command source device, a new network node is selected from the network nodes corresponding to each industrial device, and the selected network node corresponds to the industrial equipment, that is, the control command source device; a feedback module is used to receive the control command source device selected by the decision module operation, and feedback the control command source device to the system end user;

[0010] The feedback module is connected to the mobile computer device held by the system end user through a wireless network. The mobile computer held by the system end user serves as the feedback target of the feedback module and receives the selected control command source device. The system end user reads the control command source device on the mobile computer.

[0011] The construction module is interactively connected to the evaluation module and the monitoring module through a wireless network, the monitoring module is interactively connected to the acquisition module through a wireless network, the construction module is interactively connected to the identification unit through a wireless network, the evaluation module and the monitoring module are interactively connected to the identification unit through a wireless network, and the monitoring module is interactively connected to the trigger module, the decision module and the feedback module through a wireless network.

[0012] Furthermore, the building module is provided with submodules at the lower level, including:

[0013] An identification unit, used to traverse the network nodes where the industrial equipment control network uploaded in the construction module is located, and identify the parent node and child node of each network node;

[0014] In the stage of identifying the parent node and child node of the network node, the identification unit takes all the remaining network nodes after excluding the network node corresponding to the current identification target of the identification unit from the network nodes uploaded in the construction module as a set, and identifies the parent node and child node of the network node in the set;

[0015] Among them, when constructing the industrial equipment control network topology, the construction module connects the parent nodes and child nodes of the network nodes to each other based on the identification results of the parent nodes and child nodes of each network node by the identification module to form the industrial equipment control network topology.

[0016] Furthermore, when identifying the parent node and the child node of the network node, the identification unit applies the parentNode attribute to determine the parent node and the child node of each network node.

[0017] Furthermore, when the evaluation module evaluates the busyness of each network node corresponding to the industrial equipment in the industrial equipment control network topology based on the operating parameters and the industrial equipment control network topology level, the parent node in the network topology is used as the priority evaluation object. The busyness evaluation logic of the industrial equipment based on the operating parameters and the industrial equipment control network topology level is expressed as follows:

[0018]

[0019] Where: K is the busyness performance value of industrial equipment; t work is the continuous operation time of industrial equipment; f is the capacity per unit time of industrial equipment; m up is the number of parent nodes of the network node where the industrial equipment is located; m down is the number of child nodes of the network node where the industrial equipment is located; g is the progress impact of the industrial equipment relative to the product; γ is the normalization factor;

[0020] Among them, the normalization factor γ≥1, the larger the industrial equipment busyness performance value K is, the busier the industrial equipment operation state is, that is, the closer it is to the upper limit of the equipment production capacity. Conversely, the idler the industrial equipment operation state is, that is, the further away from the upper limit of the equipment production capacity.

[0021] Furthermore, the progress impact g of the industrial equipment relative to the product is obtained by the following formula:

[0022]

[0023] Where: n is the set of industrial devices corresponding to all parent nodes of the network node where the industrial device corresponding to g is located; f i is the unit time capacity of the i-th group of industrial equipment; t i The unit time used to calculate the unit time capacity of the i-th group of industrial equipment; t 0 The time it takes to produce a set of products for a group of industrial equipment;

[0024] Among them, the collection of all industrial equipment is recorded as the industrial equipment group.

[0025] Furthermore, the monitoring module is internally provided with submodules, including:

[0026] The collection unit is used to collect the network node operation status parameters in real time and feed them back to the monitoring module;

[0027] Among them, the collection unit is integrated by a network protocol analyzer, and the collected network node operation status parameters include: transmission delay, port opening and closing status, flow, and packet loss rate.

[0028] Furthermore, the monitoring logic of the industrial equipment network status in the monitoring module is:

[0029]

[0030] Where: δ is the network status security of industrial equipment; slate is the network transmission delay; m open 、m close The number of network ports opened and closed; a, a 0 is the network traffic and network traffic threshold; p loss is the packet loss rate; ω 1 ,ω 2 ,ω 3 ,ω 4 is the weight;

[0031] Among them, the larger the industrial equipment network status security δ is, the more secure the industrial equipment network status is; conversely, the worse the industrial equipment network status security is, ω 1 ,ω 2 ,ω 3 ,ω 4 The sum is 1, and ω 1 =ω 4 >ω 3 >ω 2 .

[0032] Furthermore, two sets of trigger thresholds are set in the trigger module, and the two sets of trigger thresholds are respectively applied to the busyness evaluation results of the industrial equipment based on the operating parameters and the industrial equipment control network topology level and the industrial equipment network status monitoring results. When any set of results meets its corresponding trigger threshold, the decision module is triggered to run, and based on the operation of the decision module, a control command source device is selected in the industrial equipment, and the switching operation is performed with the selected control command source device;

[0033] Among them, the control command source device is: a unique industrial device that receives the control command set by the user of the industrial equipment management end and distributes the control command to each industrial equipment in the industrial equipment group. The control command source device comes from the industrial equipment group. There is always one and only one set of control command source devices in the industrial equipment group.

[0034] Furthermore, when the decision module selects a new network node from the network nodes corresponding to each industrial device, it complies with:

[0035]

[0036] In the formula: Q is the selection tendency judgment value;

[0037] When selecting a network node, the decision module selects the network node corresponding to the maximum selection tendency judgment value Q.

[0038] Compared with the known public technology, the technical solution provided by the present invention has the following beneficial effects:

[0039] The present invention provides a networked intelligent controller. During operation, the system provides centralized management conditions for the industrial equipment control network by constructing an industrial equipment control network topology. When the operating environment of the controller of the industrial equipment group is poor, based on the set logic in the system, combined with the busyness evaluation results of the industrial equipment based on the operating parameters and the industrial equipment control network topology level and the comprehensive analysis of the industrial equipment network status, a decision is made to select the optimal controller to serve as the control command distribution source of the industrial equipment group, thereby achieving further optimization of the intelligent control and management of the industrial equipment, making the operation of the industrial equipment more intelligent and the operation process more robust.

Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0044] The present invention will be further described below in conjunction with the embodiments.

[0045] Embodiment 1:

[0046] A networked intelligent controller of this embodiment, such as Figure 1 As shown, including:

[0047] A construction module, used for uploading the network nodes where the industrial equipment control network is located, and constructing the industrial equipment control network topology based on the network nodes where the industrial equipment control network is located;

[0048] The building block is divided into sub-modules, including:

[0049] An identification unit, used to traverse the network nodes where the industrial equipment control network uploaded in the construction module is located, and identify the parent node and child node of each network node;

[0050] In the stage of identifying the parent node and child node of the network node, the identification unit takes all the remaining network nodes after excluding the network node corresponding to the current identification target of the identification unit from the network nodes uploaded in the construction module as a set, and identifies the parent node and child node of the network node in the set;

[0051] Among them, when constructing the industrial equipment control network topology, the construction module connects the parent nodes and child nodes of the network nodes to each other based on the identification results of the parent nodes and child nodes of each network node by the identification module to form the industrial equipment control network topology;

[0052] An evaluation module is used to obtain the industrial equipment control network topology, and to evaluate the busyness of each network node corresponding to the industrial equipment in the industrial equipment control network topology based on the operating parameters and the industrial equipment control network topology level;

[0053] When the evaluation module evaluates the busyness of each network node corresponding to the industrial equipment in the industrial equipment control network topology based on the operating parameters and the industrial equipment control network topology level, the parent node in the network topology is taken as the priority evaluation object. The evaluation logic of the busyness of the industrial equipment based on the operating parameters and the industrial equipment control network topology level is expressed as follows:

[0054]

[0055] Where: K is the busyness performance value of industrial equipment; t work is the continuous operation time of industrial equipment; f is the capacity per unit time of industrial equipment; m up is the number of parent nodes of the network node where the industrial equipment is located; m down is the number of child nodes of the network node where the industrial equipment is located; g is the progress impact of the industrial equipment relative to the product; γ is the normalization factor;

[0056] Among them, the normalization factor γ≥1, the larger the performance value K of the busyness of the industrial equipment is, the busier the operation state of the industrial equipment is, that is, the closer it is to the upper limit of the equipment capacity. Conversely, the idler the operation state of the industrial equipment is, that is, the farther it is from the upper limit of the equipment capacity.

[0057] Monitoring module, used to monitor the network status of each industrial equipment;

[0058] The monitoring module is internally provided with submodules, including:

[0059] The collection unit is used to collect the network node operation status parameters in real time and feed them back to the monitoring module;

[0060] The collection unit is integrated by a network protocol analyzer, and the collected network node operation status parameters include: transmission delay, port opening and closing status, flow, and packet loss rate;

[0061] The monitoring logic of the industrial equipment network status in the monitoring module is:

[0062]

[0063] Where: δ is the network status security of industrial equipment; slate is the network transmission delay; m open 、m close The number of network ports opened and closed; a, a 0 is the network traffic and network traffic threshold; p loss is the packet loss rate; ω 1 ,ω 2 ,ω 3 ,ω 4 is the weight;

[0064] Among them, the larger the industrial equipment network status security δ is, the more secure the industrial equipment network status is; conversely, the worse the industrial equipment network status security is, ω 1 ,ω 2 ,ω 3 ,ω 4 The sum is 1, and ω 1 =ω 4 >ω 3 >ω 2 ;

[0065] A trigger module is used to set a trigger threshold, obtain the busyness evaluation results of the industrial equipment based on the operating parameters and the industrial equipment control network topology in the evaluation module and the industrial equipment network status monitoring results in the monitoring module, and trigger the switching operation of the control command source device based on the comparison of the two sets of results with the trigger threshold;

[0066] The decision module is used to obtain the operation result of the trigger module. When the operation result of the trigger module is to trigger the switching of the control command source device, a new network node is selected from the network nodes corresponding to each industrial device. The selected network node corresponds to the industrial device, that is, serves as the control command source device;

[0067] When the decision module selects a new network node from the network nodes corresponding to each industrial device, it follows:

[0068]

[0069] In the formula: Q is the selection tendency judgment value;

[0070] Among them, when selecting a network node, the decision module selects the network node corresponding to the maximum selection tendency judgment value Q;

[0071] A feedback module is used to receive the control command source device selected by the decision module and feed back the control command source device to the system end user;

[0072] The feedback module is connected to the mobile computer device held by the system end user through a wireless network. The mobile computer held by the system end user serves as the feedback target of the feedback module and receives the selected control command source device. The system end user reads the control command source device on the mobile computer.

[0073] The construction module is interactively connected to the evaluation module and the monitoring module through a wireless network, the monitoring module is interactively connected to the acquisition module through a wireless network, the construction module is interactively connected to the identification unit through a wireless network, the evaluation module and the monitoring module are interactively connected to the identification unit through a wireless network, and the monitoring module is interactively connected to the trigger module, the decision module and the feedback module through a wireless network.

[0074] In this embodiment, the construction module runs to upload the network nodes where the industrial equipment control network is located, and the industrial equipment control network topology is constructed based on the network nodes where the industrial equipment control network is located. The identification unit synchronously traverses the network nodes where the industrial equipment control network uploaded in the construction module is located, and identifies the parent node and child node of each network node. The evaluation module is post-operated to obtain the industrial equipment control network topology, and the industrial equipment corresponding to each network node in the industrial equipment control network topology is evaluated based on the operating parameters and the busyness of the industrial equipment control network topology level. The monitoring module further monitors the network status of each industrial equipment, and the collection unit collects the network node operating status parameters in real time and feeds back to the monitoring module, and then the monitoring module The trigger module sets a trigger threshold, obtains the busyness evaluation results of the industrial equipment based on the operating parameters and the industrial equipment control network topology level in the evaluation module and the industrial equipment network status monitoring results in the monitoring module, and triggers the switching operation of the control command source device based on the comparison of the two sets of results with the trigger threshold. Finally, the operation result of the trigger module is obtained through the decision module. When the operation result of the trigger module is to trigger the switching of the control command source device, a new network node is selected from the network nodes corresponding to each industrial device. The selected network node corresponds to the industrial equipment, that is, it serves as the control command source device. The feedback module synchronously receives the control command source device selected by the decision module and feeds back the control command source device to the system end user.

[0075] Through the operation of the system in the above embodiment, the networked intelligent controller configured for the industrial equipment group brings further control effects, so that the controller can operate more intelligently and stably, and provide management and control services for the industrial equipment group.

[0076] See also Figure 2 As shown in the figure, another supplementary logic for the decision module to decide the control command source device based on the Leader election algorithm is given, specifically:

[0077] There are three roles involved in the Leader election algorithm. Leader represents the master node, which is elected and can receive requests from other nodes and synchronize the requests to the backup nodes. In addition, Leader needs to send heartbeat signals to other nodes regularly to maintain its leadership. Follower represents other nodes besides the master node and can participate in the vote to elect the master node. Candidate represents the candidate node, which is a temporary role in the election process. When the Follower times out and does not receive the heartbeat signal sent by the master node, it can be upgraded to Candidate to participate in the election of the master node in the next round of election.

[0078] Embodiment 2:

[0079] In terms of specific implementation, based on Example 1, this example refers to Figure 1A networked intelligent controller in Example 1 is further described in detail:

[0080] When identifying the parent node and child node of the network node, the identification unit applies the parentNode attribute to determine the parent node and child node of each network node.

[0081] Through the above settings, the identification logic of the parent node and child node of each node in the network is further limited.

[0082] like Figure 1 As shown, the progress impact g of industrial equipment relative to the product is obtained by the following formula:

[0083]

[0084] Where: n is the set of industrial devices corresponding to all parent nodes of the network node where the industrial device corresponding to g is located; f i is the unit time capacity of the i-th group of industrial equipment; t i The unit time used to calculate the unit time capacity of the i-th group of industrial equipment; t 0 The time it takes to produce a set of products for a group of industrial equipment;

[0085] Among them, the collection of all industrial equipment is recorded as the industrial equipment group.

[0086] Through the above settings, parameter support is further provided for the busyness evaluation logic of industrial equipment based on operating parameters and the industrial equipment control network topology level.

[0087] like Figure 1 As shown, two groups of trigger thresholds are set in the trigger module, and the two groups of trigger thresholds are respectively applied to the busyness evaluation results of the industrial equipment based on the operating parameters and the industrial equipment control network topology level and the industrial equipment network status monitoring results. When any group of results meets its corresponding trigger threshold, the decision module is triggered to run, and based on the operation of the decision module, a control command source device is selected in the industrial equipment, and the switching operation is performed with the selected control command source device;

[0088] Among them, the control command source device is: a unique industrial device that receives the control command set by the user of the industrial equipment management end and distributes the control command to each industrial equipment in the industrial equipment group. The control command source device comes from the industrial equipment group. There is always one and only one set of control command source devices in the industrial equipment group.

[0089] Through the above settings, the linkage operation logic between the trigger module and the decision module is further limited.

[0090] In summary, during operation, the system in the above embodiment provides centralized management conditions for the industrial equipment control network by constructing an industrial equipment control network topology. When the operating environment of the controller of the industrial equipment group is poor, based on the set logic in the system, combined with the busyness evaluation results of the industrial equipment based on the operating parameters and the industrial equipment control network topology level and the comprehensive analysis of the industrial equipment network status, a decision is made to select the optimal controller as the source of control command distribution for the industrial equipment group, thereby achieving further optimization of the intelligent control and management of industrial equipment, making the operation of industrial equipment more intelligent and the operation process more robust.

[0091] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
