BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 The figure shows a method flow chart of a HPLC carrier intelligent management method based on wireless communication according to an embodiment of the present application; Figure 2 The figure shows a schematic diagram of an HPLC carrier intelligent management system based on wireless communication provided according to an embodiment of the present application. DETAILED DESCRIPTION

[0011] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described here are only part of the embodiments of the present application, and the present application is not limited to the exemplary embodiments described here.

[0012] like Figure 1 As shown, a HPLC carrier intelligent management method based on wireless communication provided according to an embodiment of the present application may include step S100, step S200, step S300 and step S400.

[0013] In step S100, a bus topology based on HPLC is established between the concentrator, collector and smart meter in the substation, so that the concentrator and each smart meter are directly connected to each other through power lines or indirectly connected to each other through the collector as a relay node.

[0014] The smart meters in the substation area communicate with the collector via HPLC carrier or RS485 serial port. The smart meters and concentrators communicate directly via power lines or indirectly via HPLC carrier with the collector as a relay node. A bus topology based on HPLC is established between the concentrator, collector and smart meters, and a communication link for data transmission between all power devices is generated based on the bus topology.

[0015] In step S200, the concentrator sends a command to read the HPLC module ID to all smart meters in the substation, and the smart meter returns a message including the HPLC module ID and location to the concentrator in response to the command to read the HPLC module ID; the concentrator updates the communication connection status of the network node corresponding to the smart meter according to the received message, and sends the received message and the sorted abnormal data to the substation management service center module.

[0016] The power equipment in the substation area communicates with each other through networking. The concentrator sends a command to read the HPLC module ID to all smart meters in the substation area through the HPLC channel. The command to read the HPLC module ID includes a location request command. The location request command is used to read the real-time location of the smart meter to facilitate later maintenance and management. The smart meter responds after receiving the command directly sent by the concentrator or forwarded by the collector, obtains the location information through the GPS / Beidou positioning module, and returns the location information and the HPLC module ID to the concentrator in a response message. The concentrator processes the received response message according to the HPLC module ID data corresponding to the stored smart meter in the substation. If a response message is received from the network node corresponding to the smart meter, the communication connection between the concentrator and the smart meter is normal, and the response message of the network node with normal communication connection is stored. Otherwise, the communication connection between the two is abnormal. At this time, the concentrator sends a heartbeat message to the network nodes corresponding to all smart meters with abnormal communication connection to detect the communication connection status of the network node. If the network node corresponding to the smart meter receives the heartbeat message and responds to the response message, the concentrator sends the HPLC module ID read instruction to the network node again after receiving the response message detected by the heartbeat message of the network node, and the network node corresponding to the smart meter responds to the instruction. The response message is returned, and the concentrator organizes the final response message, generates a total response message of all network nodes with normal communication connection, and sends the total response message to the substation management service center module; the concentrator confirms that the communication connection of the network node corresponding to the smart meter is abnormal according to the heartbeat message detection and the instruction of reading the HPLC module ID again, and the concentrator organizes the HPLC module IDs corresponding to all network nodes with abnormal communication connection to generate a maintenance request message indicating the communication failure state, and sends the maintenance request message indicating the communication failure state to the substation management service center module; the concentrator and the substation management service center module carry out wired and wireless communication, and the wireless communication includes 4G wireless communication and micro-power wireless communication; The substation management service center module processes and stores the received message containing the HPLC module ID and location, and processes the received maintenance request message representing the communication failure status to generate corresponding warning information so that maintenance personnel can handle it as soon as possible. The warning information can be displayed in the form of a visual interface.

[0017] In step S300, the concentrator generates corresponding meter reading instructions according to the preset meter reading tasks, and issues corresponding meter reading request instructions to the smart meters in the substation. The smart meters in the substation return the requested meter reading data to the concentrator in response to the meter reading request instructions. The concentrator performs data reliability maintenance on the received meter reading data and sends the maintained meter reading data to the substation management service center module.

[0018] The concentrator generates corresponding meter reading instructions according to the meter reading tasks preset by the substation management service center module, and issues corresponding meter reading request instructions to the smart meters in the substation, and the smart meters in the substation return the requested response meter reading data to the concentrator in response to the meter reading request instructions; the concentrator processes the received response meter reading data, and for the network nodes corresponding to the smart meters that have not received the response meter reading data, the concentrator performs heartbeat message detection on the network nodes to detect whether the communication connection of the network nodes is abnormal, and sorts out the network nodes with abnormal communication after the heartbeat message detection, and generates a maintenance request message representing the communication failure state; the meter reading request instruction is sent again to the network nodes with normal communication after the heartbeat message detection to supplement the meter reading data, and the network nodes that have failed to supplement the meter reading data are sorted out to generate a maintenance request message representing the equipment failure state; Then the concentrator organizes the meter reading data to generate a meter reading response message, and sends the meter reading response message, the maintenance request message representing the communication fault state and the maintenance request message representing the equipment fault state to the substation management service center module in a wireless or wired manner.

[0019] Finally, in step S400, the substation management service center module processes, stores and analyzes the meter reading data, generates corresponding fault information and issues an early warning based on the analysis results of the meter reading data.

[0020] The substation management service center module parses the data of successful meter reading and performs reliability verification, stores the data that has passed the reliability verification, estimates the current meter reading data based on historical data for the data that has not passed the reliability verification and the smart meters for which meter reading has not been successful, and generates fault information representing meter failure for the network nodes that have not passed the reliability verification; the substation management service center module classifies and organizes the fault information and generates different warning information to facilitate management personnel to perform maintenance and processing in a timely manner.
