[0002] With the advent of the era of industrial automation, various devices in a factory are connected to a central control room for centralized control and monitoring.

[0028] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present application, not the entire structure.

[0029] Example 1

[0030] Figure 1a This is a flowchart illustrating the AUTBUS bus performance analysis and improvement method provided in Embodiment 1 of this application. This embodiment is applicable to scenarios requiring bus performance improvement. It should be noted that reduced bus performance may be due to unreasonable node parameter settings or faults in the bus, such as loose node connections, short circuits on the bus, or internal wiring faults within the nodes. Processes that address these issues to improve bus performance are all included within the scope of this embodiment.

[0031] This method can be executed by an AUTBUS bus performance analysis and enhancement device, which can be implemented in hardware and / or software and is generally integrated into a bus analyzer such as a computer with data processing capabilities. The specific steps include:

[0032] Step 101: Obtain the current node parameters of each node mounted on the bus.

[0033] In this step, multiple nodes can be connected to the bus. These nodes can contain a variety of devices, such as various sensors (transmitters), cameras, actuators, motors, etc. For details, please refer to [reference needed]. Figure 1b , Figure 1b This is a schematic diagram of a bus topology provided for Embodiment 1 of this application.

[0034] like Figure 1b As shown, the bus topology is a loop network structure with matching resistors at both ends of the network. TN represents a node, TN1 is a valve actuator, TN2 is a differential pressure transmitter, TN3 is a temperature transmitter, TN4 is a level transmitter, TN5 is a flow transmitter, TN15 is a flow control valve A, TN16 is a flow control valve B, TN17 is a camera, TN18 is a motor (M), and TN19 is a pressure transmitter.

[0035] Additionally, the analyzer shown in the figure refers to the bus analyzer in the subsequent embodiment, which can be mounted on any location on the bus. Of course, for easy connection to a host computer (PC), the analyzer can be mounted on the bus located in the central control room.

[0036] In addition, the node parameters in this step refer to parameters related to bus performance, such as signal-to-noise ratio, matching value, communication mode, and packet error rate. These parameters directly reflect the bus performance, such as bus status information and signal quality.

[0037] Step 102: Analyze the bus performance based on the node parameters, and determine the bus performance improvement plan based on the analysis results.

[0038] In this step, we can analyze the reasons for various bus performance degradations, and for each reason, there will be corresponding bus performance improvement solutions. For example, if we determine that the reason for the bus performance degradation is due to unreasonable node parameter settings or a fault in the bus, there will be corresponding bus performance improvement solutions.

[0039] It should be noted that the process of determining the cause of bus performance degradation based on node parameters can be as follows: compare the node parameters with standard parameter values ​​to obtain the difference between the node parameters and standard parameter values, pre-set several threshold ranges and mapping relationships with various causes of bus performance degradation, and then determine which threshold range the aforementioned difference falls into, thereby determining the corresponding cause of bus performance degradation.

[0040] In a specific example, the reasons for the degraded bus performance include unreasonable node parameter settings and faults in the bus. The difference between the node parameters and the standard parameter values ​​will be different due to different reasons. For example, unreasonable node parameter settings will often cause the difference to be concentrated in a certain threshold range, while the difference caused by faults in the bus will be concentrated in another threshold range. Generally, different threshold ranges can be determined by multiple field measurements and manual cause judgment.

[0041] Of course, after analyzing the cause in this embodiment, it can be shown to the user, who can then judge whether the analysis result is correct and provide feedback on the corresponding judgment result. This embodiment can update the threshold range based on the feedback judgment result.

[0042] Faced with different causes of bus performance degradation, this step will further determine a bus performance improvement plan based on the cause. This plan is designed to overcome the aforementioned causes of bus performance degradation. For example, if the cause is unreasonable node parameter configuration, then reasonable parameters will be recommended as a bus performance improvement plan, which the user can then adjust according to. If the cause is a bus fault, the approximate location of the fault, i.e., the fault range, and the corresponding preset fault elimination plan can be inferred from the analysis results. This can be used as a bus performance improvement plan, allowing the user to locate the fault range and eliminate the fault using the preset fault elimination plan, thereby improving bus performance.

[0043] Step 103: Showcase the bus performance improvement solutions so that users can improve bus performance based on the showcased solutions.

[0044] In this step, the solution can be presented so that users can improve bus performance based on the presented solution.

[0045] To further reduce manual troubleshooting, this embodiment can set two modes for the bus analyzer: manual mode and automatic mode. In manual mode, the bus performance improvement scheme can be demonstrated by following step 103.

[0046] In automatic mode, in addition to following step 103, bus performance can also be improved directly based on the bus performance enhancement scheme. Specifically, the node to be adjusted and the target node parameter values ​​can be determined according to the bus performance enhancement scheme; the node parameters of the node to be adjusted are then adjusted to the target node parameter values ​​to improve bus performance.

[0047] Of course, automatic mode is only applicable when the bus performance degradation is caused by unreasonable node parameter configuration. For bus faults, manual repair is still required.

[0048] In this embodiment, the current node parameters of each node connected to the bus are obtained, and then the bus performance is analyzed based on these node parameters. A bus performance improvement plan is determined based on the analysis results, and finally, the bus performance improvement plan is displayed so that users can improve bus performance using the displayed plan. Based on this, by analyzing node parameters and determining corresponding bus performance improvement plans, and then displaying these plans, users can improve bus performance using the displayed plans. This embodiment's approach directly analyzes node parameters to generate suitable solutions that improve bus performance, avoiding manual troubleshooting, improving troubleshooting efficiency, lowering the entry barrier for staff, and reducing labor costs.

[0049] Example 2

[0050] For cases where bus performance degradation is caused by improper node parameter configuration, the process for deriving bus performance improvement solutions can be found in [reference needed]. Figure 2 , Figure 2 This is a flowchart illustrating a bus performance improvement scheme provided in Embodiment 2 of this application.

[0051] like Figure 2 As shown in this embodiment, the process of obtaining a bus performance improvement scheme may include:

[0052] Step 201: For any sub-parameter, compare it with the standard parameter value corresponding to the sub-parameter to obtain the comparison result.

[0053] In this step, a sub-parameter is a parameter that is subordinate to the node parameters. For example, if the node parameters include signal-to-noise ratio, matching value, communication mode, and packet error rate, then the signal-to-noise ratio is a sub-parameter. Similarly, the matching value, communication mode, and packet error rate are each a sub-parameter.

[0054] It should be noted that the standard parameter value is the value that the node parameter needs to reach when the bus performance is normal. For example, when the bus performance is normal, the signal-to-noise ratio of the transmitter needs to be higher than value A. Then value A can be set as the standard parameter value of the corresponding signal-to-noise ratio of the transmitter.

[0055] The standard parameter values ​​differ for different types of nodes. For example, transmitters, cameras, or actuators require different communication capabilities. Therefore, different standard parameter values ​​need to be set for different types of nodes. For instance, the standard parameter value for the signal-to-noise ratio of a transmitter is value A1, and the standard parameter value for the signal-to-noise ratio of an actuator is value B1, etc. Please refer to Table 1 below for details.

[0056] Table 1

[0057] Node Type Standard Parameter Value Transmitter Signal-to-noise ratio: value Al; match value: value A2; communication mode: value A3; packet error rate: value A4 Actuator Signal-to-noise ratio: value Bl; match value: value B2; communication mode: value B3; packet error rate: value B4 Camera Signal-to-noise ratio: value Cl; match value: value C2; communication mode: value C3; packet error rate: value C4 Motor Signal-to-noise ratio: value Dl; match value: value D2; communication mode: value D3; packet error rate: value D4

[0058] Based on Table 1 above, for any sub-parameter, first determine the target node type of the corresponding node, and then, according to the preset mapping relationship between node types and parameter values, determine the parameter value corresponding to the target node type as the standard parameter value corresponding to the sub-parameter. For example, if the obtained value is... Figure 1b For the node parameters of the TN1 valve actuator, the sub-parameter of error rate corresponds to the node target node type of actuator. From Table 1, we can see that the standard parameter value is B4.

[0059] The sub-parameter is compared with the standard parameter value, that is, the difference between the two is calculated, and the difference is used as the comparison result of this step.

[0060] Step 202: Determine the comparison results corresponding to each sub-parameter as the analysis results, and determine the target sub-parameter to be adjusted and the corresponding adjustment value based on the analysis results.

[0061] In this step, the comparison result, i.e. the difference obtained above, can be used as the analysis result. Since each sub-parameter will have a corresponding analysis result, this step needs to determine in turn which sub-parameter can be used as the target sub-parameter, i.e. the sub-parameter whose parameter value needs to be adjusted.

[0062] Since the analysis result is the difference between the current value of the sub-parameter and the standard parameter value, and the standard parameter value is the parameter value corresponding to normal bus performance, the sub-parameter with a non-zero difference can be identified as the target sub-parameter, and then the difference can be identified as the corresponding adjustment value.

[0063] Furthermore, in order to improve the tolerance of the solution in this embodiment, a threshold can be set. When the difference reaches the threshold, the corresponding sub-parameter will be determined as the target sub-parameter, and the difference will be determined as the adjustment value.

[0064] Step 203: Determine the target sub-parameters and their corresponding adjustment values ​​as the bus performance improvement scheme.

[0065] In this step, the target sub-parameters and their corresponding adjustment values ​​are directly determined as the bus performance improvement scheme. When the bus analyzer is in manual mode, the target sub-parameters and their corresponding adjustment values ​​are displayed, and then the user adjusts the target sub-parameters according to the displayed content and the adjustment values.

[0066] When the bus analyzer is in automatic mode, it directly sends adjustment commands to the corresponding nodes according to the adjustment values ​​to adjust the target sub-parameters of the nodes to the standard parameter values.

[0067] Example 3

[0068] For cases where bus performance degradation is caused by bus failure, the process of developing a bus performance improvement plan can be found in [reference needed]. Figure 3 , Figure 3 This is a flowchart illustrating a bus performance improvement scheme provided in Embodiment 3 of this application.

[0069] like Figure 3 As shown, the process of obtaining the bus performance improvement scheme provided in this embodiment may include:

[0070] Step 301: Determine the bus direction with the target trend of signal-to-noise ratio change according to the topology of each node in the bus.

[0071] In this step, topology refers to the topological location of each node's connection on the bus. (Refer to...) Figure 1b This refers to the topology in a specific example. Importantly, it's the order of the nodes within the topology; this embodiment can determine the fault location based on the order of the nodes.

[0072] It should be noted that the target change trend can be a gradually decreasing trend. Generally, the higher the signal-to-noise ratio, the better the communication quality. When a fault occurs, the signal-to-noise ratio will gradually increase from the fault point. That is to say, the signal-to-noise ratio at the fault point is the lowest. Since the signal-to-noise ratio is a sub-parameter of the node, the closer the node is to the fault point, the lower the node's signal-to-noise ratio.

[0073] Therefore, in this step, the nodes can first be sorted according to the topology of the nodes in the bus. Then, the target nodes with the target trend in signal-to-noise ratio (SNR) are queried in the sorted list, along with the directional order of the target nodes showing the target trend. Then, the first target node in the directional order is determined as the starting node, and the bus direction with the target trend in SNR is determined based on the directional order and the starting node.

[0074] The sorting can start from the master node in the bus, or from the node closest to the bus analyzer. Figure 1b For example, the sorting order is TN1, TN2, TN3, TN4, TN5, TN15, TN16, TN17, TN18, TN19.

[0075] In a specific example, the signal-to-noise ratios (SNRs) of each node could be 48, 40, 35, 30, 20, 30, 32, 45, 50, and 52, respectively. The target trend is decreasing, and this can occur in two directions. The target nodes for each direction are TN1, TN2, TN3, TN4, TN5 and TN19, TN18, TN17, TN16, TN15, TN5. The order of the directions is the same as the aforementioned SNR from high to low, with the starting nodes being TN1 and TN19, respectively.

[0076] Step 302: Compare the signal-to-noise ratios of each node along the bus direction. If the signal-to-noise ratio of the current node is less than both the signal-to-noise ratio of the previous node and the signal-to-noise ratio of the next node, the area between the previous node and the next node of the current node is determined as the fault zone.

[0077] This step mainly involves identifying nodes whose signal-to-noise ratio (SNR) is simultaneously less than both the SNR of the previous node and the SNR of the next node. This can generally be done by comparing each node one by one, i.e., traversing the network. In a specific example, the SNR of TN5 is simultaneously less than that of TN4 and TN15, which means that a fault has occurred near TN5. To facilitate users in locating the fault on-site, the area between the previous node and the next node can be defined as the fault interval, i.e., the area between TN4 and TN15 is the fault interval.

[0078] Step 303: Determine the fault range and the preset fault elimination scheme as the bus performance improvement scheme.

[0079] In this step, the preset fault elimination plan is a pre-recorded fault inspection and elimination operation manual. Generally, bus faults can include open circuits, short circuits, etc. For each type of fault, the specific operation manual can be recorded separately.

[0080] To help less experienced users eliminate obstacles, the fault ranges obtained in the aforementioned steps, along with pre-stored preset fault elimination schemes, can be recommended to users as bus performance improvement solutions. Users can then use the operation manuals to detect and eliminate faults in the fault ranges.
