In order to solve the above problem, in the embodiments of the present application, all the state parameters are subjected to unit division, so as to provide a system for automatically notifying and responding to a change of state of a system unit, so as to implement automatic notification and responding to a change of state of a system unit, thereby greatly improving the efficiency of responding to a change of state of a system unit.
Fig. 1 is a schematic diagram illustrating a subscription relationship between system units of an automatic notification and response system for a system unit state change according to an embodiment of the present application. As shown in fig. 1, the automatic notification and response system has a plurality of status parameters, and all the status parameters are divided into units, so that the system includes a plurality of monitoring units and/or monitored units, and when a system unit has a monitoring attribute, the system unit is called a monitoring unit, which includes a plurality of status parameters; a system element is referred to as a monitored element when it has monitored properties, and it contains several status parameters. When a certain state parameter in the monitored unit changes, the certain state parameter in the monitoring unit responds to the change of the certain state parameter, so that the two state parameters respectively positioned in different system units are a pair of state parameters with a change response relation, and further, the monitored unit to which the state parameter with the independent variable attribute belongs and the monitoring unit to which the state parameter with the dependent variable attribute belongs have a monitoring relation. It should be noted that, if the same system unit includes both the state parameters of the independent variable attributes and the state parameters of the dependent variable attributes, the system unit is both a monitoring unit and a monitored unit for different state parameters. In addition, if the same system unit only contains state parameters of a plurality of independent variable attributes, the system unit is a monitored unit; and if the same system unit only contains the state parameters of a plurality of dependent variable attributes, the system unit is a monitoring unit.
Specifically, referring to FIG. 1, the system presence parameters A, B, C, D, E, F, G, divide these state parameters into four units, such that system unit 1 is provided with parameters A and B; system unit 2 contains parameters C, D, E; the system unit 3 presence parameter E; the system unit 4 contains a parameter G. Wherein, the parameter A responds to the change of the parameter C, D (the parameter A, C has a change response relationship; the parameter A, D has a change response relationship), the parameter E responds to the change of the parameter F (the parameter E, F has a change response relationship), and the parameter G responds to the change of the parameter B (the parameter G, B has a change response relationship), so that the system unit 1 monitors the state change of the system unit 2 (the units 1 and 2 have a monitoring relationship), the unit 1 is a monitoring unit, and the unit 2 is a monitored unit; the system unit 2 monitors the state change of the system unit 3 (the units 2 and 3 have monitoring relation), the unit 2 is a monitoring unit, and the unit 3 is a monitored unit; the system unit 4 monitors the state change of the system unit 1 (the units 4 and 1 have a monitoring relation), the unit 4 is a monitoring unit, and the unit 1 is a monitored unit. Further, both the system units 1 and 2 include the state parameters of the independent variable attributes and the state parameters of the dependent variable attributes, so that the system unit 1 is a monitoring unit and a monitored unit at the same time, and the system unit 2 is a monitoring unit and a monitored unit at the same time; the system unit 3 only contains the state parameters of the independent variable attributes, so the system unit 3 is a monitored unit; the system unit 4 only contains the state parameters of the dependent variable attributes, so the system unit 4 is a monitoring unit.
FIG. 2 is a diagram of a system architecture for an automatic notification and response system for system unit state changes, according to an embodiment of the present application. The system is provided with a plurality of monitoring units, a plurality of monitored units, and a notification response unit (the automatic notification and response system has only one notification response unit). As shown in fig. 2, the system includes, for a pair of state parameters having a change response relationship: a monitoring unit 23, a monitored unit 21, and a notification scheduling unit 22. A monitored unit 21 that measures and monitors a change in a state parameter included in the unit, and when any state parameter in the unit changes, transmits a state change notification for the changed state parameter; a notification scheduling unit 22, which determines the monitoring relationships between all monitored units 21 and all monitoring units 23, constructs a scheduling relationship network, receives the state change notifications sent by all monitored units 21, and forwards the state change notifications to the monitoring unit 23 having the monitoring relationship with the monitored unit 21 by using the scheduling relationship network; and a monitoring unit 23 having a plurality of state parameters, wherein the monitoring unit 23 receives and analyzes the state change notification transmitted from the notification scheduling unit 22, updates the state parameter in the unit in response to the changed state parameter in the monitored unit 21, and completes the response of the state change of the system unit.
The following describes each unit composition in detail.
First, the monitored unit 21 includes a notification module 212 and a status monitoring module 211. The state monitoring module 211 includes self-state information of all state parameters in the unit, monitors a change of the state parameters in the unit by using the self-state information, and sends the self-state information of the changed state parameters to the notification module 212 when any state parameter in the unit changes, where each changed state parameter corresponds to one piece of self-state information, and the self-state information includes: the encoding of the changed state parameter (argument property parameter), and the new value of the argument property parameter after the change. And a notification module 212 having a status notification function, which receives and analyzes the self status information of the changed status parameter, writes the analysis result in the status change notification, and forms and outputs a status change notification for the changed status parameter. It should be noted that, when a plurality of state parameters in the same monitored unit 21 change, one state change notification (a plurality of state change notifications are transmitted) needs to be transmitted for each state parameter, only for the change of one state parameter having the argument attribute, where the state change notifications include: the sender (monitored unit 21 to which the changed state parameter belongs) code, the changed state parameter (argument attribute parameter) code, and the new value of the changed state parameter.
Next, the monitoring unit 23 includes a subscription information sending module 231, a notification receiving module 232, and a notification responding module 233. The following describes the configuration of the monitoring unit 23 in detail. The subscription information sending module 231 determines the monitored unit 21 having a monitoring relationship with the unit based on the change response relationship of the state parameters in all the system units, further obtains subscription information for the unit, and sends the subscription information to the notification scheduling unit 22, so as to subscribe the state change notification sent by the monitored unit 21 having a monitoring relationship with the monitoring unit 23. Specifically, the subscription information sending module 231 stores all the change response relationship parameter information with the dependent variable attribute parameters in the monitoring unit 23, where the change response relationship parameter information includes a dependent variable attribute parameter code and an independent variable attribute parameter code having a change response relationship with the dependent variable attribute parameter code, and sends subscription information composed of system unit codes to which each parameter in the change response relationship parameter information belongs to the notification scheduling unit 22 as a subscription notification. It should be noted that the subscription notification is only for subscription information of a pair of system units having a monitoring relationship, and represents that the subscription notification is subscribed to a state change notification sent by the monitored unit 21, and if the monitoring unit 23 and the plurality of monitored units 21 all have a monitoring relationship, the subscription notification needs to be sent for each monitored unit 21, where the subscription information includes: a monitoring unit code and a code of a monitored unit having a monitoring relationship with the present monitoring unit 23. The notification reception module 232 will be explained below. And a notification receiving module 232, which receives and analyzes the status change notification sent by the notification scheduling unit 22, acquires the code of the changed status parameter and the new value thereof, and outputs the code to a notification responding module 233. A notification response module 233, which receives the analysis result of the notification receiving module 232, retrieves the change response relation parameter information having the dependent variable attribute parameter corresponding to the independent variable attribute parameter from the subscription information sending module 231 by using the acquired independent variable attribute parameter code, acquires the dependent variable attribute parameter code to be updated and the new value after the dependent variable parameter is changed, updates the corresponding dependent variable attribute parameter in the monitoring unit 23, and further outputs response action information and/or a response instruction for the updating of the monitoring unit 23.
After receiving the notification of the change of the bearing rotating speed, a monitoring unit obtains a specific numerical value of the changed bearing rotating speed parameter, an output device (such as a display screen and a printer) unit is used as a monitored unit to which the monitoring unit monitors the bearing rotating speed parameter, after analyzing the state change notification, a parameter (dependent variable attribute parameter) which has a response relation with the bearing rotating speed parameter in the output device unit is updated, further, the dependent variable attribute parameter is compared with a preset safe rotating speed in the output device unit, and if the bearing rotating speed exceeds the safe rotating speed, a forced braking instruction is output.
Finally, the notification scheduling unit 22 will be explained. The notification scheduling unit 22, which includes a notification forwarding module 222, a subscription record storage module 221, and a communication record storage module 223, is responsible for receiving and forwarding the state change notification. Specifically, the subscription record storage module 221 receives and stores subscription information sent by all the monitoring units 23, and obtains a scheduling relationship network for subscription relationships among all the system units. The notification forwarding module 222 receives and parses the state change notification sent by the monitored unit (sender) 21, obtains a sender code, invokes subscription information corresponding to the parsed sender code in the scheduling relationship network, and forwards the state change notification to and only to a corresponding subscriber based on a subscriber (the monitoring unit 23 that has subscribed to the state change notification of the monitored unit 21) code in the subscription information. In addition, the communication record storage module 223 is provided with a communication record, writes the forwarded state change notification into the communication record, and is used for inquiring and positioning system faults caused by measurement or hardware communication problems; when a system fault or a certain state parameter is abnormal, an operator can fetch the forwarding record related to the specific parameter in the communication record and position a fault source.
FIG. 3 is a data and key signal flow diagram for an automatic notification and response system for system unit state changes according to an embodiment of the present application; FIG. 4 is a flowchart illustrating steps of a method for automatically notifying and responding to system operation of a system unit status change according to an embodiment of the present application. The operation of the automatic notification and response system will be described with reference to fig. 3 and 4. As shown in fig. 3 and 4, first, in step S410, it is necessary to determine all status parameter pairs having change response relationship in the system, so as to determine attributes of all system units (whether the attributes of the system units are monitoring units 23 or monitored units 21), and monitoring relationships between all monitored units 21 and all monitoring units 23, and obtain change response relationship parameter information and subscription information in the monitoring units 23, and self status information in the monitored units 21, further, all monitoring units 23 send subscription information for the unit to the notification scheduling unit 22, subscribe to the status change notification of the monitored units 21 having monitoring relationship with the monitoring units 23, further, the notification scheduling unit 22 receives and integrates the subscription information sent by all monitoring units 23, and establishes a scheduling relationship network for relationships between all system units, then, the process proceeds to step S420, where the subscription information includes: monitored unit code, and code of a monitoring unit having a monitoring relationship with the monitored unit 21. (step S420) the monitored unit 21 monitors the change of the status parameters contained in the unit, and when any status parameter of any monitored unit 21 in the system changes, generates the own status information for all the changed status parameters, and sends the own status information to the notification module 212 of the monitored unit 21, so as to construct a status change notification for each changed status parameter, so that the monitored unit 21 where all the changed status parameters exist sends a status change notification to the notification scheduling unit 22, where the status change notification includes the following contents: monitored unit code, changed state parameter code, and new value after state parameter change. Then, step S430 is performed, after the notification scheduling unit 22 receives the state change notification, the state change notification is analyzed to obtain a corresponding sender code (monitored unit code), the scheduling relationship network is utilized to retrieve subscription information corresponding to the sender code, determine a subscriber code (monitoring unit 23 having a monitoring relationship with the monitored unit 21), and finally, forward the state change notification to the monitoring unit 23 where the state parameter in another system unit affected by the changed state parameter is located; meanwhile, the forwarded state change notice is written into a communication record for inquiring and positioning system faults caused by measurement or hardware communication problems. Finally, (step S440) the monitoring unit 23 receives the status change notification forwarded by the notification scheduling unit 22 and then analyzes the status change notification, and the monitoring unit 23 obtains the changed status parameter code and the new value after the status parameter change based on the analysis result of the status change notification, and updates the status data in the monitoring unit 23 having the changed response relationship with the changed status parameter, so as to update the status of the monitoring unit 23, and output the response action information and/or the response instruction caused by the status change of the unit, thereby completing the response of the status change of the system unit.
(one example)
There is a cell A, B, C, D, E, F in a system where cell A, B needs to monitor the state of cell C, D, E and cell B needs to monitor the state of A, F. When the unit A, B, C, D, E, F has a status change, it sends a status change notification to the notification scheduling unit; after receiving the notification of the state change, the notification scheduler sends the state change notification of the unit C, D, E to the unit A, B; a state change notification of A, F is sent to B. Further, after receiving the state change notifications of the units C, D, and/or E, the unit A, B updates the corresponding dependent variable attribute state parameters in the unit A, B according to the specific change values of the independent variable attribute state parameters, and outputs a response instruction and/or a corresponding action instruction; and after receiving the state change notification of the unit A and/or the unit F, the unit B updates the corresponding dependent variable attribute state parameters in the unit B according to the specific change values of the independent variable attribute state parameters, and outputs a response instruction and/or a corresponding action instruction.
The method comprises the steps of dividing a system into units, establishing a monitoring relation among the system units based on the corresponding relation among the state parameters, further establishing a scheduling relation network of the whole system units, introducing a notification scheduling unit, and when the state parameters in the system units change, forwarding a state change notification including a state parameter updating value to the system unit to which the state parameter influenced by the changed state parameter belongs through the notification scheduling unit, and further completing data updating. Under the automatic notification and response mode, the monitoring and the measurement aiming at the state parameters are only completed in the unit to which the parameters belong, the number of links of the whole system is the same as that of the units, and each system unit can complete the updating of the parameters only through the information interaction with the notification scheduling unit, so that the local change response efficiency among the system units is greatly improved, and the reliability of the system is enhanced.
The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
