Description

Technical Field

[0001] The present invention relates to an electric circuit wiring status analysis system and a node status analysis method based on power line carrier. Specifically, it relates to an analysis method and system for the connection equipment, non-connection equipment, line sequence status and line status between electrical devices at each node of the electric circuit. Background Art

[0002] A Chinese invention patent application with publication number CN105277839A discloses a wiring status detection method for detecting the wiring status between an instrument and a test piece in a simulated electrical test, comprising the following steps: after any instrument issues a wiring detection request, a continuous frequency signal is generated inside the instrument and sent through the wired cable; the test piece connected to the any instrument records the signal frequency of the continuous frequency signal, and the signal frequency data is sent to the any instrument via a wireless network; after receiving the signal frequency data, the any instrument analyzes and processes it and displays the wiring status of the wired cable between the test piece connected to it.

[0003] Chinese invention patent application CN115856715A provides a single-phase AC line wiring status detection circuit that can be used to detect normal wiring, missing ground wire, missing neutral wire, reversed live and neutral wire connections, and reversed live and ground wire connections. While it can determine the wiring status and line sequence of a connection point, it is designed for single-phase AC lines.

[0004] Therefore, traditional wiring status detection only collects voltage data, current data or frequency data to analyze the status of each node when the line is powered on. It can only analyze the abnormal status of two nodes in the carrier feeder from the data, but cannot accurately determine the incoming and outgoing line connections of the corresponding nodes, and cannot analyze the line sequence status through data. It cannot provide effective data support for the precise positioning of faults and the status of the wiring of each node, and it cannot analyze the status of the line when the carrier feeder is powered off.

[0005] Therefore, it is necessary to provide a solution that can analyze the connected equipment, unconnected equipment, line sequence status and line status between various electrical devices at each node of the carrier feeder. Summary of the Invention

[0006] The purpose of the present invention is to solve the problems existing in the prior art and to provide a method and device for analyzing the connection status of a carrier feeder based on a power carrier.

[0025] Among them, the three carrier modules of the electrical main circuit outgoing line carrier module of node 1 and the three carrier modules of the electrical main circuit incoming line carrier module of node 2 are combined to adopt three carrier modules; Specifically, the electrical main circuit incoming line carrier module of node 1 includes carrier module 1, carrier module 2, and carrier module 3, and the electrical main circuit outgoing line carrier module of node 1 includes carrier module 8, carrier module 9, and carrier module 10; The electrical main circuit incoming line carrier modules of node 2 include carrier modules 8 , 9 , and 10 , and the electrical main circuit outgoing line carrier modules of node 2 include carrier modules 19 , 20 , and 21 .

[0028] Specifically, the carrier feeder incoming carrier module of node 1 includes carrier module 4, carrier module 5, carrier module 6, and carrier module 7, and the carrier feeder outgoing carrier module of node 1 includes carrier module 11, carrier module 12, carrier module 13, and carrier module 14; The carrier feeder incoming carrier module of node 2 includes carrier module 15, carrier module 16, carrier module 17, and carrier module 18.

[0029] Serial Device Server It is connected to the RS232 or RS485 interfaces of the electrical main circuit incoming carrier module, the electrical main circuit outgoing carrier module, the carrier feeder incoming carrier module and the carrier feeder outgoing carrier module respectively through its RS232 interface, and is communicatively connected with the computing unit for forwarding downlink data, the first uplink data and the second uplink data.

When the main electrical circuit power supply is out of power, it switches to the isolated low-voltage auxiliary detection power supply to provide a carrier for data transmission. When the main electrical circuit power supply is powered, the isolated low-voltage auxiliary detection power supply is cut off and switched to the main electrical circuit power supply to provide a carrier for data transmission.

[0032] The node status analysis method of the electric circuit connection status analysis system based on the power line carrier of this embodiment includes the following steps: Step 1: The computing unit sends the first data to be detected as downlink data. After being forwarded by the serial port server, the first data to be detected (A1, B1, C1) is transmitted to the main electrical circuit by the electrical main circuit incoming carrier modules (carrier module 1, carrier module 2, carrier module 3) of node 1. Step 2: The data to be detected collected by each of the carrier modules 8, 9, 10, 19, 20, and 21 are uploaded to the computing unit via the serial port server as first uplink data. The data to be detected collected by carrier module 4, carrier module 5, carrier module 6, carrier module 7, carrier module 11, carrier module 12, carrier module 13, carrier module 14, carrier module 15, carrier module 16, carrier module 17, carrier module 18, carrier module 22, carrier module 23, carrier module 24, and carrier module 25 are respectively uploaded to the computing unit through the serial port server as the second uplink data; Step 3: After receiving the first uplink data and the second uplink data forwarded by the serial device server, the computing unit performs the following analysis and judgment: Step 3.1: First analyze the wiring status of the electrical main circuit of node 2, and then analyze the wiring status of the electrical main circuit of node 1; If the electrical main circuit connection state of the node to be analyzed is determined to be normal, proceed to step 3.3; if the electrical main circuit connection state of the node to be analyzed is determined to be abnormal, proceed to step 3.2.

[0033] The electrical main circuit connection status of the node is judged as follows: if the data to be detected collected by carrier modules 8, 9, and 10 and the data to be detected collected by carrier modules 19, 20, and 21 are all consistent with the first detection data, then the electrical main circuit connection of node 2 is normal; otherwise, the electrical main circuit connection of node 2 is abnormal; If the data to be detected collected by carrier modules 8, 9, and 10 are consistent with the first detection data, the wiring of the electrical main circuit of node 1 is normal; otherwise, the wiring of the electrical main circuit of node 1 is abnormal; Table 1 The electrical main circuit wiring status of nodes 1 and 2 are both normal Table 2 The electrical main circuit wiring status of node 1 is abnormal, and the electrical main circuit wiring status of node 2 is abnormal As shown in Table 1, carrier modules 8, 9, and 10 collect data to be detected (A1, B1, C1), and carrier modules 19, 20, and 21 collect data to be detected (A1, B1, C1). Therefore, the electrical main circuit connections of nodes 1 and 2 are normal.

[0034] As shown in Table 2, carrier modules 8, 9, and 10 collect data to be detected (A1, ×, C1), and carrier modules 19, 20, and 21 collect data to be detected (A1, ×, C1). Therefore, the electrical main circuit connections of nodes 1 and 2 are abnormal.

[0035] As shown in Table 3 below, assuming that the wiring of node 1 incoming line B is abnormal, it will cause the wiring of node 1 electrical main circuit to be abnormal; Table 3 The electrical main circuit wiring status of node 1 is abnormal, and the electrical main circuit wiring status of node 2 is normal As shown in Table 3, if carrier modules 1, 2, and 3 collect data to be tested (A2, ×, C2), the wiring of the main electrical circuit of node 1 is abnormal. If carrier modules 19, 20, and 21 collect data to be tested (A2, B2, C2), the wiring of the main electrical circuit of node 2 is normal.

[0036] Step 3.2, analyzing the connection status of each node to be analyzed; First determine the incoming wiring status of the node to be analyzed and then determine the outgoing wiring status of the node to be analyzed.

[0037] When determining the incoming line connection status of node 2, the computing unit sends second data to be detected to carrier module 8, carrier module 9, and carrier module 10 of node 2 via the serial port server; it is determined whether the data to be detected collected by carrier module 15, carrier module 16, carrier module 17, and carrier module 18 of node 2 is consistent with the second data to be detected. If they are consistent, it is determined that the incoming line connection status of node 2 is normal; if they are inconsistent, it is determined that the incoming line connection status of node 2 is abnormal; When judging the outgoing wiring status of node 2, if the data to be detected collected by the carrier module 22, carrier module 23, carrier module 24, and carrier module 25 of node 2 are consistent with the second data to be detected, the outgoing wiring status of node 2 is judged to be normal; if the data to be detected collected by the carrier module 22, carrier module 23, carrier module 24, and carrier module 25 of node 2 are inconsistent with the second data to be detected, the outgoing wiring status of node 2 is judged to be abnormal.

[0038] When determining the incoming line connection status of node 1, the computing unit sends second data to be detected to carrier module 1, carrier module 2, and carrier module 3 of node 1 via the serial port server; it is determined whether the data to be detected collected by carrier module 4, carrier module 5, carrier module 6, and carrier module 7 of node 1 are consistent with the second data to be detected. If they are consistent, it is determined that the incoming line connection status of node 1 is normal; if they are inconsistent, it is determined that the incoming line connection status of node 1 is abnormal; When judging the outgoing wiring status of node 1, if the data to be detected collected by the carrier module 11, carrier module 12, carrier module 13, and carrier module 14 of node 1 are consistent with the second data to be detected, the outgoing wiring status of node 1 is judged to be normal; if the data to be detected collected by the carrier module 11, carrier module 12, carrier module 13, and carrier module 14 of node 1 are inconsistent with the second data to be detected, the outgoing wiring status of node 1 is judged to be abnormal.

[0039] As shown in Table 4, it is assumed that the wiring of the incoming line B of node 1 is abnormal, which causes the wiring of the main electrical circuit of node 1 to be abnormal; Table 4 The incoming wiring status of node 1 is abnormal, and the status of node 2 is normal As shown in Table 4, carrier modules 1, 2, and 3 send out the first detection data (A1, B1, C1), carrier modules 8, 9, and 10 collect the data to be detected (×, B1, C1), and carrier modules 19, 20, and 21 collect the data to be detected (×, B1, C1). Therefore, the electrical main circuit connections of nodes 1 and 2 are abnormal.
