Description

Technical Field

[0001] This invention belongs to the field of power safety operation technology, specifically relating to an intelligent alarm method and system for grounding wire devices in substations, power distribution lines and other similar applications. Background Technology

[0002] In power system maintenance, installing grounding wires is a crucial technical measure to protect the lives of workers and prevent electric shock accidents caused by sudden power surges. The correct installation and removal of grounding wires is paramount and must follow a strict operating sequence: during installation, connect the grounding end first, then connect the conductor end (i.e., the connecting end); during removal, the sequence is reversed: remove the conductor end first, then remove the grounding end. Any incorrect sequence, poor contact, omission, or accidental removal can lead to serious electric shock accidents. Currently, some technologies attempt to monitor the status of grounding wires, such as Bluetooth or WiFi-based monitoring systems that upload grounding wire data to a backend management system, requiring cloud services and a management host. However, these technical solutions have significant drawbacks: firstly, they typically rely on wireless network infrastructure covering the work area, resulting in high investment costs and poor signal stability in environments with strong electromagnetic interference, such as substations; secondly, existing solutions primarily focus on remote monitoring, lacking local, real-time audible and visual alarms, failing to alert operators on-site immediately; and no solution effectively integrates pressure monitoring and operational sequence logic, failing to completely eliminate safety hazards caused by poor contact and incorrect sequence. Therefore, there is an urgent need for a grounding wire monitoring solution that is low-cost, highly reliable, capable of local alarm, and can intelligently determine the installation / removal sequence and contact status. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an intelligent alarm method and system for grounding wire devices in substations, power distribution lines and other applications. By collecting pressure data from the grounding end and the connection end of the grounding wire, the system determines whether the contact is good. By controlling the connection sequence of the grounding wire, it avoids electric shock accidents caused by accidental disconnection, missed disconnection, incorrect disconnection sequence, or poor contact, thus ensuring the safety of power workers and solving the technical problems mentioned in the background art.

[0004] The objective of this invention is achieved as follows: an intelligent alarm method for a grounding wire device, comprising the following steps: S1, collecting pressure data at the grounding end and the connection end of the grounding wire; S2, transmitting the pressure data at the grounding end and the connection end to a data aggregation module; S3, after receiving the pressure data, the data aggregation module performs a status judgment to determine whether the contact pressure between the grounding end and the connection end is abnormal; S4, the data aggregation module monitors the installation and removal sequence of the grounding wire, performs logical judgment based on the positional status of the grounding end and the connection end, and confirms whether the operation is performed in a preset order; the preset order is: during installation, the grounding end is installed first, followed by the connection end; during removal, the connection end is installed first, followed by the grounding end; S5, when the pressure data is abnormal or the installation and removal sequence is incorrect, an alarm signal is triggered. By monitoring the direct physical quantity of "pressure," the reliability of the "electrical connection" is indirectly determined, and the "sequence" of the operation process is converted into a "state sequence" that can be recognized by the logic circuit for monitoring. Complex safety rules (good contact, correct sequence) are transformed into a measurable and verifiable data model. During implementation, when operators use the grounding wire, the system automatically executes a cyclical check of "data acquisition (S1), data transmission (S2), status judgment (S3), and sequence monitoring (S4)." If an abnormality is detected in step S3 or S4, an alarm is immediately triggered (S5), interrupting the unsafe operation. The system abstracts the "process knowledge" of operating procedures (grounding before connecting the wire, disconnecting the wire before disconnecting the ground), which relies on human experience, into "logical judgments" based on state transitions, achieving automated monitoring of the program. This shifts from relying on personnel's "passive compliance with procedures" to the system's proactive "real-time monitoring and mandatory alarms," ​​significantly reducing the risk of human error and improving the safety of power operations.

[0005] In step S1, grounding pressure data is collected by a grounding pressure sensor installed at the grounding end of the grounding wire, and hanging pressure data is collected by a hanging pressure sensor installed at the hanging end of the grounding wire. In practice, a pressure sensor (such as a thin-film pressure sensor or a piezoresistive sensor) is physically installed at both the grounding end and the hanging end of the grounding wire, and integrated into the clamp structure. This distributed, fixed-point pressure sensing scheme, unlike video surveillance or position sensors, can directly sense the effect (pressure) of the "contact" action, rather than just "approach" or "visibility," making it more direct, accurate, and with strong anti-interference capabilities.

[0006] In step S2, the pressure data from the connection end is transmitted to the connection end data aggregation module via a first wired method, and then from the connection end data aggregation module to the grounding end data aggregation module via a first wireless method, namely Bluetooth transmission. Simultaneously, the pressure data from the grounding end is transmitted to the grounding end data aggregation module via a second wired method. In implementation, the connection end sensor is connected to the "data aggregation module" (which can be a simple signal conditioner and wireless transmitter) on the operating lever via a short wire. This module sends data to the grounding end "data aggregation module" (main processor) via Bluetooth, while the grounding end sensor is directly connected to the main processor via a wire. This method requires no external network, offers high reliability, is cost-effective, and perfectly adapts to the substation environment.

[0007] In step S3, the status determination involves comparing the grounding terminal pressure value and the connection terminal pressure value with their respective preset pressure thresholds. If either pressure value is lower than its corresponding preset threshold, it is determined to be an abnormal contact pressure. During implementation, a pressure threshold (e.g., 50N) is set for both the grounding terminal and the connection terminal in the data aggregation module program. When the real-time pressure value remains below the threshold, it is determined to be "poor contact." This dual-threshold independent comparison strategy allows the thresholds for the grounding terminal and the connection terminal to be set separately according to actual conditions, resulting in greater accuracy.

[0008] In step S4, the position status logic values ​​are defined by the states of the grounding pressure sensor and the mounting pressure sensor. Good contact is defined as the first logic value, and no contact or poor contact is defined as the second logic value. If the sequence of logic value changes during the installation and removal process does not conform to the preset logic, it is considered an incorrect sequence. This transforms the physical world's operational sequence into a verification problem of a digital logic sequence. During implementation, the pressure sensor states are binary (e.g., normal pressure = logic '1', abnormal pressure = logic '0'). The correct installation sequence corresponds to the following logic sequence: grounding (0->1), then mounting (0->1). Any deviation from this sequence (e.g., mounting changes to 1 before grounding) results in an error. No additional displacement or visual sensors are required; pressure data is reused to achieve a second layer of safety monitoring.

[0009] In step S5, the alarm trigger signal includes triggering a local audible alarm or sending an alarm SMS to a designated remote mobile terminal via the wireless communication module built into the data aggregation module. In practice, when an anomaly occurs, a high-decibel buzzer alarm immediately sounds on-site to warn the operator; simultaneously, an alarm SMS is sent to the mobile phone of the person in charge or the monitoring center via the 4G / GSM module. This achieves comprehensive safety warning coverage, preventing on-site personnel from making mistakes and enabling timely intervention by management personnel, thus forming a closed-loop safety management system.

[0010] A smart alarm system for a grounding wire device, used to implement the above-mentioned method, includes: a mounting end pressure sensor installed at the mounting end of the grounding wire for real-time acquisition of mounting end pressure data; a grounding end pressure sensor installed at the grounding end of the grounding wire for real-time acquisition of grounding end pressure data; a mounting end data collection module fixedly installed at the mounting end of the grounding wire operating rod, wiredly connected to the mounting end pressure sensor, for reading the mounting end pressure data, and equipped with a wireless transmission module; a grounding end data aggregation module fixedly installed at the grounding end of the grounding wire, wiredly connected to the grounding end pressure sensor, and equipped with a wireless receiving module for receiving the mounting end pressure data from the mounting end data collection module and the directly read grounding end pressure data; the grounding end data aggregation module includes a processing unit for performing pressure status judgment and installation / removal sequence logic judgment, and generating an alarm command when an abnormality is detected; and an alarm device connected to the grounding end data aggregation module for executing the alarm command.

[0011] The alarm device includes: a sound alarm, integrated into the data aggregation module or connected to its wire, for emitting an audible warning; and a wireless communication module, integrated into the data aggregation module, for sending SMS alerts to a designated remote mobile terminal. Both the mounting end pressure sensor and the grounding end pressure sensor are static pressure sensors.

[0012] The beneficial effects of this invention are as follows: It indirectly judges the reliability of electrical connections by monitoring the direct physical quantity of "pressure," and transforms the operational process "sequence" into a "state sequence" that can be recognized by logic circuits for monitoring. Complex safety rules (good contact, correct sequence) are transformed into a measurable and judgmental data model. During implementation, when operators use the grounding wire, the system automatically executes a cyclical detection of "data acquisition, data transmission, state judgment, and sequence monitoring." Once an abnormality is detected in any step, an alarm is immediately triggered, interrupting unsafe operations. The "process knowledge" of operating procedures (grounding before connecting, disconnecting before grounding), which relies on human experience, is abstracted into "logical judgment" based on state transitions, achieving automated monitoring of the program. This transforms reliance on "passive compliance with procedures" by personnel into proactive "real-time monitoring and mandatory alarms," ​​greatly reducing the risk of human error and improving the safety of electrical operations. Through a dual-threshold independent comparison judgment strategy, the thresholds for the grounding and connection ends can be set separately according to actual conditions, resulting in greater accuracy.
