[0002] The importance of monitoring and identifying the usage link of intelligent grounding wires for the safety monitoring of the operation site is as follows: grasping the usage status in real time and monitoring the connection status, that is, intelligent monitoring can perceive in real time whether the grounding wire is firmly connected.

[0007] In a further aspect of the present invention, when the power supply state of the detector is normal power supply, the communication state of the detector is normal communication, the connection state of the incoming power end is in the unconnected state, and the pressure value at the grounding end is less than the first threshold, it is determined that the current state of the grounding wire is the ready state.

[0008] In a further aspect of the present invention, when the power supply state of the detector is normal power supply, the communication state of the detector is normal communication, the connection state of the incoming power end is in the connected state and the duration of the state is less than the second threshold, and the pressure value at the grounding end is greater than the first threshold and the duration of the state is less than the second threshold, it is determined that the current state of the grounding wire is the installed state.

[0009] In a further aspect of the present invention, when the power supply state of the detector is normal power supply, the communication state of the detector is normal communication, the connection state of the incoming power end is in the connected state and the duration of the state is greater than the second threshold, and the pressure value at the grounding end is greater than the first threshold and the duration of the state is greater than the second threshold, it is determined that the current state of the grounding wire is the monitoring state.

[0010] In a further aspect of the present invention, when the power supply state of the detector is normal power supply, the communication state of the detector is normal communication, the connection state of the incoming power end is in the unconnected state, and the pressure value at the grounding end is less than the first threshold, it is determined that the current state of the grounding wire is the disassembly state.

[0011] In a further aspect of the present invention, when the power supply state of the detector is non-powered, the communication state of the detector is communication interrupted, the connection state of the incoming power end is in the unconnected state, and the tightness state of the grounding end is less than the first threshold, it is determined that the current state of the grounding wire is the idle state.

[0012] The second aspect of the present invention provides a monitoring system for the usage status of a temporary intelligent power grounding wire, which is used to implement the method provided in the first aspect of the present invention, and includes: a data acquisition and analysis module, which is used to obtain the power supply status of the detector and the communication status of the detector; a status monitoring and identification processing module, which is used to generate the current status of the grounding wire and whether the grounding wire is in an abnormal working condition according to the power supply status of the detector, the communication status of the detector, the hanging status of the incoming line end, and the tightening status of the grounding end.

When the installation / removal operation process of the intelligent grounding wire is abnormal, the intelligent grounding wire monitoring software automatically triggers voice alarms and indicator light alarms to remind the operators to comply with the safety regulations for grounding wire operations and prevent personal, equipment, and power grid accidents. (2) When any one of the phase hooks clamping the conductor has an abnormality (loosening or falling off) or the connection bolts of the grounding grid are loose, and the duration exceeds the set time, the monitoring module will automatically issue an alarm; when the three-phase hooks are normally installed / removed, there will be no alarm, which can effectively prevent personal, equipment, and power grid accidents. (3) The monitoring software can real-time monitor the working conditions of the installed grounding wire detectors. Before the power transmission operation, after the operators view the monitoring module, it can effectively prevent the omission of removing the grounding wire before equipment power transmission and reduce the occurrence of power grid accidents.

[0025] Please refer to Figure 1 , the first aspect of the present invention provides a method for monitoring the usage status of a temporary intelligent power grounding wire, including the following steps: S100: Obtain the power supply status and communication status of the detector; S200: Obtain the electrical connection signal of the incoming power end and the pressure value of the grounding end according to the detector; S300: Judge the hanging state of the incoming power end according to the electrical connection signal of the incoming power end, and judge the tightness state of the grounding end according to the pressure value of the grounding end; S400: Determine the current state of the grounding wire according to the power supply status of the detector, the communication status of the detector, the hanging state of the incoming power end, the tightness state of the grounding end, and the duration of the state of the hanging state of the incoming power end and the tightness state of the grounding end; S500: When the grounding wire is in the installation state, monitoring state, and disassembly state, judge whether the grounding wire is in an abnormal working condition according to the change of the pressure value of the grounding end and the sequence of the hanging state of the incoming power end and the tightness state of the grounding end.

[0026] In a further aspect of the present invention, the step of judging whether the grounding wire is in an abnormal working condition according to the continuous range of the pressure value of the grounding end and the sequence of the hanging state of the incoming power end and the tightness state of the grounding end when the grounding wire is in the installation state, monitoring state, and disassembly state includes the following steps: When the grounding wire is in the monitoring state and the pressure value at the grounding end is less than the first threshold within the target time period at any time, it is determined that the grounding wire is in an abnormal working condition; There are two types of abnormal working conditions of the grounding wire. One is that the phase wire is loosely hung, and the other is that the grounding is loosely connected.

[0027] Phase wire loosely hung: At least one of the secondary signals of the A / B / C three-phase detectors is in the off position, the pressure value of the P phase (connected to the grounding grid) is greater than the threshold, and after this situation lasts for 30 seconds (an example of a target time period), in the first monitoring module, the phase sequence indicator light corresponding to the off phase is red, and the phase sequence indicator light corresponding to the on phase is green, and a voice alarm of "Phase X is loosely hung" is sent synchronously; the color of the relevant loose-hanging phase detector position graphic element in the second monitoring module also changes successively (such as from green to red); Grounding loosely connected: The secondary signals of the A / B / C three-phase detectors are all in the on position, 0 < pressure value < threshold for the P phase (connected to the grounding grid), and after this situation lasts for 30 seconds, in the first monitoring module, the phase sequence indicator light corresponding to the P phase is red, and the phase sequence indicator lights corresponding to the A / B / C three-phase detectors in the on position are green, and a voice alarm of "P phase is loosely connected" is sent synchronously. The color of the P-phase loose-connection phase detector position graphic element in the second monitoring module also changes successively (such as from green to red).

[0028] When the grounding wire is in the installation state and the incoming end enters the hanging state first and the grounding end enters the fastening state later, it is determined that the grounding wire is in an abnormal working condition; Specifically, after the abnormal installation situation monitoring unit continuously receives the change of the A / B / C three-phase detectors from the off position to the on position (the order of the A / B / C phases is not required), and then receives the P-phase fixed signal. In the first monitoring module (monitoring device), the phase sequence indicator lights of the A / B / C phases turn green earlier than the phase sequence indicator light of the P phase, and a voice alarm of "Abnormal installation process" is sent synchronously; the color of the detector position graphic element in the second monitoring module also changes successively (such as from red to green) earlier than the phase sequence indicator light of the P phase, a voice alarm of "Abnormal installation process" is sent synchronously, and corresponding alarm logs are generated.

[0029] When the grounding wire is in the removal and installation state and the grounding end enters the fastening state first and the incoming end enters the hanging state later, it is determined that the grounding wire is in an abnormal working condition.

[0030] When the disassembly state is in an abnormal working condition, the monitoring unit first continuously receives the signals that the A, B, and C phase detectors change from the off position to the on position (the order of A, B, and C phases has no requirement), and then receives the fixed signal of the P phase. In the first monitoring module, the phase sequence indicator lights of A, B, and C phases turn green earlier than the P phase indicator light turns green, and a voice alarm of "abnormal disassembly process" is synchronously issued; in the second monitoring module, the colors of the detector position graphic elements of A, B, and C phases also change (such as changing from green to red) earlier than the P phase indicator light turns red, a voice alarm of "abnormal disassembly process" is synchronously issued, and corresponding alarm logs are generated.

[0031] In a further aspect of the present invention, the current state of the grounding wire includes: a preparation state, an installation state, a monitoring state, a disassembly state, and an idle state.

[0032] In a further aspect of the present invention, when the power supply state of the detector is normal power supply, the communication state of the detector is normal communication, the incoming end hanging state is in an unhanged state, and the tightness state of the grounding end is less than the first threshold, it is determined that the current state of the grounding wire is the preparation state. The pressure value of the grounding end is the tightness state of the grounding end. When the pressure value is greater than the first threshold, it is in a tightened state, and when the pressure value is less than the first threshold, it is in a loosened state.

[0033] It should be noted that in this embodiment, the detector includes a P phase detector and A, B, and C phase detectors. The P phase detector is used to obtain the tightness state of the grounding end, and it needs to be fixed on the fixing bolt of the grounding end when in use. The A, B, and C phase detectors are used to obtain the hanging state of the incoming end to detect the hanging states of the three-phase incoming ends respectively.

[0034] In the preparation state, when the power of the intelligent grounding detector is turned on, the wireless connections of each detector are normal, the incoming end is in an unhanged state, and the grounding end bolt is in a loosened state; the set of secondary monitoring signals corresponding to this link is: the monitoring module first receives the loosening signal of the P phase of the grounding end (the pressure sensor value is less than the threshold), and then continuously receives that the A, B, and C phase detectors are in the off position (the order of A, B, and C phases has no requirement). The corresponding three-phase sequence indicator lights in the first monitoring module are all red; in the second monitoring module (terminal monitoring software), the colors of the detector position graphic elements change successively (such as changing from gray to red and being in an active state). At this time, the monitoring software automatically marks the usage state of the intelligent grounding wire as "ready".

[0035] It should be noted that the A, B, and C phase detectors and their related color changes used in this application are only for examples and not for limiting the scope.

[0036] In a further aspect of the present invention, when the power supply state of the detector is normal power supply, the communication state of the detector is normal communication, the connection state of the incoming line end is in the connected state and the duration of the state is less than the second threshold, and the tightness state of the grounding end is greater than the first threshold and the duration of the state is less than the second threshold, it is determined that the current state of the grounding wire is the installed state.

[0037] In the installed state, the on-site operator first tightens the bolt of the grounding end of phase P, and then installs the grounding wire hook of the incoming line end (clamped and tightened with the conductor), regardless of the installation sequence of phases A, B, and C of the A, B, and C phase detectors; during this period, the operator may perform incorrect installation operation procedures of the grounding wire, that is, the conductor hook of the incoming line end is hung earlier than the tightening operation of the grounding pile bolt of the grounding end.

[0038] When the installed state is a normal installation situation, within a continuous period of time T1, the monitoring unit first receives the fixed signal of phase P, and then continuously receives the change of the A, B, and C phase detectors from the position off-position to the on-position (the order of phases A, B, and C is not required); among them, for the first monitoring module, the phase sequence indicator lights corresponding to the three phases are green; the colors of the detector position graphic elements in the second monitoring module 2 also change successively (such as changing from red to green). At this time, the control software automatically marks the usage state of the intelligent grounding wire as "installed", and generates corresponding system log records.

[0039] In a further aspect of the present invention, when the power supply state of the detector is normal power supply, the communication state of the detector is normal communication, the connection state of the incoming line end is in the connected state and the duration of the state is greater than the second threshold, and the tightness state of the grounding end is greater than the first threshold and the duration of the state is greater than the second threshold, it is determined that the current state of the grounding wire is the monitoring state.

[0040] After the intelligent grounding wire is installed, both the incoming line end and the grounding end of the intelligent grounding wire are in a reliable connection state for a long time; during operation, due to relevant reasons, loosening may occur between individual detectors and the conductor (or grounding grid), resulting in virtual hanging between the hook and the conductor or virtual connection of the connection bolt with the grounding grid. Therefore, it is necessary to monitor the data obtained by each detector in the monitoring state to identify whether the current detector is in a normal working condition or an abnormal working condition.

[0041] When the grounding wire is in a normal working condition, the secondary signals of the A, B, and C phase detectors remain in the on-position for a long time, and the colors of the detector position graphic elements in the second monitoring module also remain unchanged for a long time (that is, the duration of the state is greater than the first threshold); for the first monitoring module, the phase sequence indicator lights corresponding to the phases are green; and every once in a while, the second monitoring module will receive the regular communication "heartbeat" signals of each detector; at this time, the control software automatically marks the usage state of the intelligent grounding wire as "working link".

[0042] In a further aspect of the present invention, when the power supply status of the detector is normal power supply, the communication status of the detector is normal communication, the connection status of the incoming power terminal is in an unconnected state, and the tightness status of the grounding terminal is less than the first threshold, it is determined that the current state of the grounding wire is the disassembled state.

[0043] When the disassembled state is in the normal working condition, within a continuous period of time T2, the monitoring software first receives that the position of the three-phase detectors of A, B, and C changes from the closed position to the open position (the order of A, B, and C is not required), and then receives the fixed signal of phase P (the torque of the pressure sensor is less than the threshold). Among them, for the first monitoring module, the corresponding phase sequence indicator light is red; the color of the detector position graphic element in the monitoring module 2 (monitoring software) also changes successively (such as changing from green to red). At this time, the control software automatically marks the usage status of the intelligent grounding wire as "dismantling completed".

[0044] In a further aspect of the present invention, when the power supply status of the detector is non-powered, the communication status of the detector is communication interrupted, the connection status of the incoming power terminal is in an unconnected state, and the tightness status of the grounding terminal is less than the first threshold, it is determined that the current state of the grounding wire is the idle state.

[0045] A second aspect of the present invention provides a temporary intelligent power grounding wire usage status monitoring system, including: a data acquisition and analysis module for obtaining the power supply status of the detector and the communication status of the detector; a status monitoring and identification processing module for generating the current state of the grounding wire and whether the grounding wire is in an abnormal working condition according to the power supply status of the detector, the communication status of the detector, the connection status of the incoming power terminal, and the tightness status of the grounding terminal.

[0046] Specifically, it further includes a status identification logic configuration module, a status monitoring and identification processing module, a usage status display module, and an alarm and log recording module. After the data of the front-end sensor working condition module is processed, it can identify and mark the various usage statuses of the intelligent grounding wire (preparation, installation, monitoring, disassembly, idle) and display them through the usage status display module, improving the ability of operators to perceive the status of the grounding wire in real time, quickly locate faults, and supervise the operation process of the grounding wire, etc., realizing timely prevention of electric shock and other accidents, avoiding equipment failures caused by grounding wire problems, and reducing operation and maintenance costs and time with the help of remote monitoring and intelligent identification.

[0047] Furthermore, the usage status display module is provided with a specific display area (abnormal) and display graphics for monitoring the "grounding wire installation condition", "detector abnormal signal", and "manual setting signal", so that operators can quickly master the usage status of the grounding wire and improve the monitoring efficiency of operators.

[0048] Specifically, for the convenience of operators, the usage status display module specifically includes the following content and interface: (1)The installed grounding wire monitoring interface includes: monitoring the working conditions of the installed grounding wires at the substations or on-site maintenance of transmission lines operated and maintained by the unit, and displaying them according to a predefined template, specifically including: serial number, substation (or tower) name, grounding wire group number, installation location, actual positions of A / B / C / P sensor working conditions (closed position, open position, abnormal position or divided position), monitoring unit (communication status, comprehensive alarm information), installation time, latest refresh time, etc. The data refresh interval is 5 minutes (the refresh time can be set).

[0049] After the operator completes the installation of the grounding wire, the grounding wire detector automatically uploads the working condition data of the grounding wire, synchronously adds a record of the grounding wire group number on the "installed grounding wire" monitoring interface, and a corresponding grounding wire installation record should be generated in the alarm monitoring window. After the corresponding grounding wire is removed, the grounding wire with the corresponding group number in the "installed grounding wire" interface is automatically deleted, and a corresponding grounding wire removal record should be generated in the alarm monitoring window.

[0050] (2)The "abnormal signal" monitoring interface includes: the detector reports the abnormal and unrecovered signals of the grounding wire working conditions, dynamically displays all the abnormal and unrecovered signals, and displays them according to a predefined template. The specific content includes the line tower name, abnormal information name, latest action time (signal change), and latest data update time.

[0051] (3)The "manual setting" signal monitoring interface includes: dynamically displays all the manually set signals and displays them according to a predefined template, specifically including: manual setting information name, latest setting time (signal change).

[0052] In case of abnormal sampling of the grounding wire detector, resulting in frequent signal changes, the position of a specific sensor can be manually set to a specified position. After manual setting, manual resetting is required to restore the normal working mode.

[0053] In a further aspect of the present invention, it further includes: a detector for obtaining the connection status of the incoming end and the tightness status of the grounding end; a communication module electrically connected to the detector and the data acquisition and analysis module to send the connection status of the incoming end and the tightness status of the grounding end obtained by the detector to the data acquisition and analysis module.

[0054] Further, it includes a grounding wire connection detection module, a communication module, and a usage status monitoring module; the grounding wire connection condition detection module is respectively connected to the incoming power conductor and the grounding grid at the grounding end, and monitors the clamping and fastening condition with the conductor (or grounding grid) in real time, and sends the monitoring data to the monitoring module in real time; the communication module forms a wireless network at the operation site and is wirelessly connected to the detector for detecting the grounding wire connection condition and the monitoring module respectively, providing a channel for the transmission of the working condition data of each detector; the usage status monitoring module receives and analyzes the working condition data uploaded by the grounding wire connection detector, and after comprehensive calculation and discrimination, displays it in the form of graphics, voice, text, etc.

[0055] The present invention timely identifies the usage status link of the intelligent power grounding wire by comprehensively judging the grounding wire working condition data, monitors and masters the grounding wire status in real time, timely prevents accidents such as electric shock, avoids equipment failures caused by grounding wire problems, and reduces the operation and maintenance costs and time with the help of remote monitoring and intelligent identification.

[0056] In a third aspect of the present invention, a computer-readable medium stores computer programs / instructions thereon, and when the computer programs / instructions are executed by a processor, the steps provided in the first aspect of the present invention are implemented.

[0057] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
