[0002] With the continuous development of the power grid system, the parameters of each node in the power grid system are also constantly changing.

[0055] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0058] The embodiments of the present invention are further described below in conjunction with the accompanying drawings.

[0059] like Figure 1 As shown, Figure 1 is a schematic diagram of a system architecture 100 of a power monitoring system data processing cluster provided by an embodiment of the present invention. Figure 1 In the example, the system architecture 100 of the power monitoring system includes a remote terminal unit 110, a computing and processing cluster 120 and a management terminal 130. The remote terminal unit 110 is used to obtain power information, and the power information is used to characterize the electrical parameters in the power grid; the computing and processing cluster 120 includes multiple nodes 121, each of which is connected to the remote terminal unit 110, and the node 121 is used to process power information; the management terminal 120 is respectively connected to the remote terminal unit 110 and each node 121, and is used to send a heartbeat packet to each node 121 to detect the working status of the node 121.

[0060] The system architecture and application scenarios described in the embodiments of the present invention are intended to more clearly illustrate the technical solutions of the embodiments of the present invention, and do not constitute a limitation on the technical solutions provided by the embodiments of the present invention. Those skilled in the art will appreciate that with the evolution of the system architecture and the emergence of new application scenarios, the technical solutions provided by the embodiments of the present invention are equally applicable to similar technical problems.

[0061] It can be understood by those skilled in the art that Figure 1 The structure of the system architecture 100 shown in the figure does not constitute a limitation on the embodiments of the present invention, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0062] Based on the structure of the above system architecture, various embodiments of the heartbeat detection method of the present invention are proposed.

[0063] like Figure 2 As shown, Figure 2 It is a flowchart of a heartbeat detection method provided by an embodiment of the present invention. The heartbeat detection method is applied to the management end in the system architecture in the above embodiment. The heartbeat detection method includes but is not limited to step S100, step S200, step S300 and step S400.

[0064] Step S100, establishing a first process, the first process is used to implement the communication function of the management end.

[0065] In one embodiment, the first process is also used to implement the data processing function of the management end.

[0066] In one embodiment, each node is connected to the management end, and each node obtains power information from a remote terminal unit (RTU, Remoteterminal unit). The power information is used to characterize the electrical parameters in the power grid, and a processing result is generated based on the power information, and finally the processing result is sent to the management end.

[0067] Step S200: establishing a first heartbeat receiving thread under a first process, where the first heartbeat receiving thread is used to detect the working status of the node.

[0068] In one embodiment, the first heartbeat receiving thread is used to obtain a second heartbeat data packet sent by a node to detect a working status of the node.

[0069] Step S300, receiving the first heartbeat data packet or alarm information through the first heartbeat receiving thread, the first heartbeat data packet is sent by the second process, and the first heartbeat data packet is used to characterize the working status of the second process; the second process is established by the node, and the second process is used to send the first heartbeat data packet to the management end while processing the power information, the power information is obtained by the node from the remote terminal unit, and the power information is used to characterize the electrical parameters in the power grid.

[0070] In one embodiment, the first heartbeat data packet is sent by the second heartbeat sending thread under the second process of the node. At the same time, the second process is also used to process power information. Therefore, there is a thread for processing power information under the second process. Therefore, when the management end cannot receive the second heartbeat data packet normally, it means that the second heartbeat sending thread under the second process is deadlocked and failed. Since the thread for processing power information is also established under the second process, the thread for processing power information under the second process is also in a deadlocked and failed state.

[0071] In one embodiment, the first heartbeat data packet carries result information obtained by the node according to the power information. Therefore, when the node sends the first heartbeat data packet to the management end to indicate its own working status, it can also complete the transmission of the result information.

[0072] In one embodiment, the node is provided with a third process to detect the status of the second process, and is capable of caching data from the remote terminal unit to prevent data loss when the second process deadlocks and fails, and is capable of sending an alarm signal to the management end to inform the management end of the deadlock and failure of the second process.

[0073] Step S400, starting timing each time a first heartbeat data packet is received, and determining that the second process is deadlocked and invalid when the timing time exceeds a first preset time or an alarm message is received.

[0074] In one embodiment, when the timing time exceeds the first preset time, it means that the second heartbeat sending thread is deadlocked and invalid, that is, all threads under the second process are deadlocked and invalid.

[0075] In one embodiment, the first preset time is set to 1000 milliseconds.

[0076] In addition, in one embodiment, referring to Figure 3 The heartbeat detection method may also include but is not limited to the following steps:

[0077] Step S500, establishing a first heartbeat sending thread under the first process, the first heartbeat sending thread is used to indicate the working status of the management end to the node;

[0078] Step S600: sending a second heartbeat data packet to the node through the first heartbeat sending thread at every second preset time interval, where the second heartbeat data packet is used to represent the working status of the first process.

[0079] In one embodiment, a first heartbeat sending thread is further provided under the first process, and the first heartbeat sending thread is used to send a second heartbeat data packet to the node, and the node can determine the working status of the first process by obtaining the second heartbeat data packet.

[0080] In one embodiment, the second preset time is set to 200 milliseconds.

[0081] In addition, in one embodiment, referring to Figure 4 In step S600, sending a second heartbeat data packet to the node through the first heartbeat sending thread at every second preset time interval may include but is not limited to the following steps:

[0082] Step S610: obtaining address information of the node according to the first heartbeat data packet, where the address information is used to represent the physical address of the node.

[0083] Step S620: sending a second heartbeat data packet to the node according to the address information at intervals of a second preset time, and the second heartbeat data packet is sent through the first heartbeat sending thread.

[0084] In one embodiment, the first heartbeat data packet carries the address information of the node, so when the node works abnormally, the physical address of the node can be located through the address information to maintain the faulty node.

[0085] Specifically, in one embodiment, the address information may represent the IP address of the node, or may represent the MAC address of the node, which is not specifically limited in this embodiment.

[0086] It should be noted that, in one embodiment, the address information may represent a virtual address assigned to the node by the power monitoring system, or may be a unique hardware address of the node, which is not specifically limited in this embodiment.

[0087] In addition, in one embodiment, referring to Figure 5 The heartbeat detection method may also include but is not limited to the following steps:

[0088] Step S700: When the second process fails, a first restart instruction is sent to the node according to the address information, where the first restart instruction is used to restart the second process.

[0089] In one embodiment, after detecting that a node is deadlocked and failed, the management end can send a first restart instruction according to address information corresponding to the failed node to restart the second process.

[0090] It should be noted that the process in the node for receiving the first restart instruction to restart the node is independent of the second process.

[0091] like Figure 6 As shown, Figure 6 It is a flowchart of a heartbeat detection method provided by another embodiment of the present invention. The heartbeat detection method is applied to the nodes in the system architecture in the above embodiment. The heartbeat detection method includes but is not limited to step S800, step S900, step S1000, step S1100 and step S1200.

[0092] Step S800, establishing a second process, the second process is used to process power information, the power information is obtained by the node from the remote terminal unit, the power information is used to characterize the electrical parameters in the power grid.

[0093] In one embodiment, the second process is also used to implement the data processing function of the node, and a thread for processing the power information acquired by the remote terminal unit is also provided under the second process.

[0094] In one embodiment, each node is connected to the management end, and each node obtains power information from a remote terminal unit, the power information is used to characterize the electrical parameters in the power grid, and generates processing results based on the power information, and finally sends the processing results to the management end.

[0095] Step S900: establishing a second heartbeat sending thread under the second process, and the second heartbeat sending thread is used to indicate the working status of the node to the management end.

[0096] Step S1000: sending a first heartbeat data packet to the management end through a second heartbeat sending thread at intervals of a second preset time, where the first heartbeat data packet is used to represent the working status of the node.

[0097] In one embodiment, the first heartbeat data packet is sent by the second heartbeat sending thread under the second process of the node. At the same time, the second process is also used to process power information. Therefore, there is a thread for processing power information under the second process. Therefore, when the management end cannot receive the second heartbeat data packet normally, it means that the second heartbeat sending thread under the second process is deadlocked and failed. Since the thread for processing power information is also established under the second process, the thread for processing power information under the second process is also in a deadlocked and failed state.

[0098] Step S1100, establishing a third process, the third process is used to monitor whether the second process fails;

[0099] Step S1200: When the second process fails, data from the remote terminal unit is cached through the third process, and an alarm message is sent to the management terminal through the third process.

[0100] In one embodiment, the alarm information is sent by a third process, and the third process is used to monitor whether the second process fails, and can cache data from the remote terminal unit when the second process fails. The first process starts timing each time the first heartbeat data packet is obtained, and determines that the second process is deadlocked and failed when the timing time exceeds the first preset time or the alarm information is received. Since a second heartbeat sending thread for indicating the working status of the node to the management end is established under the second process of the node, and the second process is also responsible for processing the power information obtained by the remote terminal unit, when the thread responsible for processing the power information under the second process is deadlocked, all threads under the second process including the second heartbeat sending thread will be in a deadlocked and failed state, so that the first process of the management end can determine whether the second process is deadlocked and failed through the first heartbeat data packet. In addition, by setting a third process at the node to detect the status of the second process, it is possible to cache data from the remote terminal unit when the second process is deadlocked and failed to prevent data loss, and it is possible to send an alarm signal to the management end to let the management end know that the second process is deadlocked and failed.

[0101] In addition, in one embodiment, referring to Figure 7 The heartbeat detection method may also include but is not limited to the following steps:

[0102] Step S1300: establish a second heartbeat receiving thread in the second process, and the second heartbeat receiving thread is used to detect the working status of the management end.

[0103] Step S1400: receiving a second heartbeat data packet sent by the management end through a second heartbeat receiving thread, where the second heartbeat data packet is used to represent the working status of the management end.

[0104] In one embodiment, a first heartbeat sending thread is also provided under the first process, and the first heartbeat sending thread is used to send a second heartbeat data packet to the node. The node can obtain the second heartbeat data packet through the second heartbeat receiving thread to determine the working status of the first process.

[0105] In one embodiment, since the second heartbeat data packet is sent by the first heartbeat sending thread under the first process of the management end, and other processes for realizing management end communication and data processing are also provided under the first process, the failure of other threads under the first process can be indirectly judged by failing the first heartbeat sending thread.

[0106] Step S1500, starting timing each time a second heartbeat data packet is received, and determining that the first process is deadlocked and invalid when the timing time exceeds a first preset time.

[0107] In one embodiment, the first heartbeat data packet is sent by the second heartbeat sending thread under the second process of the node. At the same time, the second process is also used to process power information. Therefore, there is a thread for processing power information under the second process. Therefore, when the management end cannot receive the second heartbeat data packet normally, it means that the second heartbeat sending thread under the second process is deadlocked and failed. Since the thread for processing power information is also established under the second process, the thread for processing power information under the second process is also in a deadlocked and failed state.

[0108] In addition, in one embodiment, referring to Figure 8 The heartbeat detection method may also include but is not limited to the following steps:

[0109] Step S1600: When the first process deadlock fails, a second restart instruction is sent to the management end, where the second restart instruction is used to restart the management end.

[0110] In one embodiment, after detecting that the management end is deadlocked and failed, the node can send a second restart instruction to the management end to restart the management end.

[0111] It should be noted that the process in the management terminal for receiving the second restart instruction to restart the management terminal is independent of the first process, so that the management terminal cannot be restarted due to the deadlock of the first process.

[0112] It should be understood that the various steps in the above flowchart are displayed in sequence according to the indication of the arrows, but these steps are not necessarily executed in sequence in the order indicated by the arrows. Unless there is a clear description in this article, there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders. Moreover, at least a part of the steps in the above flowchart may include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
