A Study on Improving Emergency Repair Efficiency Through the Use of Smart Tool Management Cabinets in the Intelligent Management of Tools at Electric Power Companies

Power grid operation and maintenance, emergency repairs, and equipment inspections are core tasks for ensuring the safe and stable operation of the power grid. PossessingHighly unpredictable, strict time constraints, high safety standards, dispersed work sites, and a wide variety of tools and equipmentIndustry-specific characteristics. Whether it involves daily line inspections, routine equipment maintenance, or emergency repairs for power grid failures caused by extreme weather conditions such as typhoons, heavy rains, or ice accumulation, operations must rely on standardized, comprehensive, and properly maintained power safety tools, maintenance equipment, and emergency supplies. The speed of emergency repairs directly determines the time required to restore the power grid, the reliability of power supply to customers, and the service performance metrics of power companies. Meanwhile, the level of tool and equipment management is a key factor influencing the response speed of emergency repairs, operational safety, and construction efficiency.

At present, most grassroots power supply stations, operations and maintenance teams, and substation emergency repair warehouses still rely on traditional, manual tool management models—characterized by paper ledgers, manual record-keeping, on-site inventory counts, and tool distribution handled by designated personnel. In emergency repair scenarios, common issues include time-consuming tool searches, cumbersome borrowing and return procedures, unclear tool status, tools being left behind or forgotten, the mixed use of expired or overdue-for-inspection tools, and delayed inventory checks upon return to the warehouse. These issues not only prolong emergency repair preparation times and delay the restoration of power to affected areas but also pose significant safety hazards—such as electric shock, tool failure, and operational violations—seriously hindering the standardized and efficient conduct of power emergency repairs.

The Smart Tool Management Cabinet is a digital, intelligent control device developed to meet safety supervision standards in the power industry and to support emergency repair operations. It integrates core technologies such as RFID “one item, one code” identification, biometric access control, intelligent temperature and humidity regulation, end-to-end data traceability, automatic inventory counting and alerts, and periodic calibration reminders. It enables closed-loop, full-lifecycle management of power emergency repair tools, covering “inventory registration upon entry, self-service issuance, status monitoring, rapid retrieval, return verification, periodic calibration, and decommissioning and archiving.” Based on the actual operating conditions of emergency repair operations in power enterprises, this paper systematically analyzes the core pain points of traditional tool management that hinder repair efficiency. It conducts an in-depth study of the technical adaptation logic, efficiency improvement pathways, typical application scenarios, and practical value of intelligent tool management cabinets, providing theoretical and practical references for power enterprises to upgrade their tools to smart systems, enhance the quality and efficiency of emergency repairs, and standardize safe operations.

I. Key Challenges in Traditional Tool Management at Electric Power Companies That Hinder Emergency Repair Efficiency

Electrical emergency repair operations place extremely high demands on tools in terms of “timeliness, completeness, compliance, and safety,” Traditional manual warehouse management models are severely out of step with modern rapid repair systems. Efficiency gaps exist throughout the entire process—from repair preparation and on-site operations to post-operation return to storage and debriefing—and have become the primary bottleneck hindering efforts to improve the quality and speed of power grid emergency repairs.

First, the process for issuing emergency repair equipment is cumbersome, and the preparatory work takes too long. Traditional electrical tool warehouses rely on manual registration, item-by-item verification, and handwritten ledger entries. When emergency repair personnel collect insulated tools, voltage detectors, climbing equipment, and maintenance supplies, each issuance takes more than 5 minutes. In scenarios such as nighttime emergency repairs, sudden faults during holidays, or bulk emergency repairs during extreme weather, insufficient warehouse staff and bottlenecks in the registration process become particularly problematic, significantly prolonging the preparation time before dispatch and delaying the critical window for restoring power. A large number of emergency repair tasks are delayed due to the time-consuming processes of tool retrieval, verification, and inventory checks, resulting in a delayed overall response time and directly impacting the efficiency of power grid fault restoration.

Second, the unclear status of tools can easily lead to rework and safety hazards. Electrical insulation tools, safety equipment, and testing devices are subject to strict annual inspection, calibration, and withstand voltage test cycles. Traditional ledgers cannot provide dynamic cycle reminders, making it impossible to promptly identify tools in the warehouse that are overdue for inspection, have failed performance checks, or have been damaged by moisture. The misuse of substandard tools during emergency repairs not only renders inspection data invalid, necessitates rework, and prolongs fault resolution times, but also leads to safety incidents such as electric shock and secondary equipment damage, resulting in dual losses: reduced repair efficiency and increased safety risks. Furthermore, traditional warehouses lack constant temperature and humidity control. As a result, insulated tools are subject to prolonged exposure to moisture, aging, and deterioration, which significantly reduces their reliability and increases the likelihood of failures during field operations.

Third, the tool inventory records are disorganized, and issues such as tools being left behind, taken by mistake, or lost occur frequently. Power emergency repair tools come in a wide variety of types, encompassing hundreds of categories and specifications, including insulated operating tools, personal safety equipment, climbing equipment, lifting equipment, testing instruments, and emergency consumables. Traditional manual inventory counts suffer from low accuracy and data lag, resulting in a long-standing discrepancy between recorded inventory and actual inventory. During emergency repairs, staff are unable to quickly verify the completeness of their tool sets, leading to issues such as critical tools being left behind, missing spare tools, and mismatched specifications. This results in work stoppages on-site and the need for multiple trips to retrieve missing items, significantly extending repair times. Additionally, since tool issuance is not tied to specific personnel and lacks traceability, it is impossible to accurately assign responsibility for lost, damaged, or overdue tools. This results in the continuous loss of tool resources and redundant procurement, further undermining the ability to ensure a reliable supply of emergency repair materials.

Fourth, emergency repairs lack data support, making it difficult to optimize workflows. Traditional manual ledgers can only record the time of tool issuance; they cannot link this information to emergency repair work orders, personnel, work scenarios, or tool usage frequency and wear and tear. Companies are unable to accurately track tool consumption patterns for various emergency repair tasks, the wear-and-tear cycles of frequently used tools, or the proportion of idle tools. Consequently, it is difficult to optimize tool allocation, inventory reserves, and the dispatch model for emergency repair supplies in a targeted manner. With long-term reliance on manual, experience-based management, it is challenging to improve the standardization, precision, and digitization of emergency repair operations.

II. Core Technical Principles Underlying the Adaptation of Smart Tool Management Cabinets to Emergency Power Repair Scenarios

The smart tool management cabinet is tailor-made to meet the core requirements of emergency power repairs—namely, “sudden occurrence, high standards, high safety, and rapid response”—and relies onRFID smart identification technology, biosafety access control, smart environmental regulation, big data lifecycle management, and data integration with safety supervision systemsFive core technologies are reshaping the management processes for electrical tools, fundamentally addressing the efficiency shortcomings and security vulnerabilities of traditional models from a technical perspective, and providing digital support to enhance emergency repair efficiency.

The system attaches a unique anti-metal RFID tag to each electrical tool, establishing a one-to-one code-to-item relationship and creating a unique identity record. It accurately records comprehensive information, including the tool model, specifications, date of receipt, calibration cycle, withstand voltage test records, and applicable work scenarios. The cabinet is equipped with a high-frequency read/write module capable of batch-identifying multiple tools in 0.3 seconds. A full inventory is automatically completed the moment the door is closed, compressing the traditional manual inventory process—which used to take tens of minutes—into a matter of seconds, thereby significantly improving the efficiency of material verification prior to emergency repairs. Compared to traditional manual verification, the smart recognition mode ensures zero errors and zero omissions, completely eliminating issues such as tool mismatches and missed verifications.

The system features a multi-layered access control system that includes facial recognition, ID card swiping, and password verification. It can integrate with power companies’ safety supervision management systems to enable tiered control of job-specific access rights and linked verification of workers’ qualifications. Unauthorized personnel cannot check out high-voltage insulation equipment or tools for high-risk operations, thereby eliminating the risk of unauthorized checkouts at the source. Once authorized, emergency repair personnel can quickly and independently check out and return tools without the need for manual registration or dedicated staff supervision. The time required for a single checkout or return is reduced to less than 30 seconds, significantly streamlining the tool checkout process for emergency repairs and meeting the demands of 24-hour emergency response operations. At the same time, every access record is automatically stored, and the data is permanently tamper-proof, enabling full traceability of tool usage and pinpointing individual accountability.

To address the essential storage needs for electrical insulation tools, the cabinet is equipped with built-in smart temperature and humidity control, as well as dehumidification and dust-proofing modules. These automatically adjust temperature and humidity based on the warehouse environment, maintaining a dry and stable storage condition for the insulation tools. This effectively prevents moisture damage, aging, and performance degradation, ensuring the reliability of emergency repair tools during on-site operations. The system features a built-in intelligent early-warning algorithm that allows users to customize tool calibration cycles, expiration dates, and inventory thresholds. It issues alerts for tools that are overdue for calibration, nearing expiration, or below inventory thresholds, tools that have not been returned after their due date, automatically triggering audible and visual alerts as well as SMS notifications. This enables the timely completion of tool calibration, restocking, and return verification, thereby preventing non-compliant tools from being used in emergency repair operations.

In addition, The smart tool management cabinet supports seamless integration with power operation and maintenance MES systems, power grid safety supervision platforms, and emergency repair work order systems.

III. Key Strategies for Improving the Efficiency of Emergency Power Repairs Through Smart Tool Management Cabinets

1. Streamline the outbound process and reduce the response time prior to emergency repairs

Most efficiency losses in emergency power repairs occur during the pre-deployment stages of tool organization, verification, and registration. Under the traditional model, emergency repairs for sudden outages require ad hoc inventory checks, item-by-item registration, and manual verification of tool completeness; these preparatory steps are time-consuming and result in missed opportunities to restore power at the optimal time. The smart tool management cabinet establishes an unattended, self-service tool retrieval system that enables repair personnel to quickly retrieve and return tools 24/7. The system automatically handles registration, accounting, and inventory updates without the need for manual intervention. Compared to the traditional model, repair preparation time can be reduced by more than 60%. Response speeds are significantly improved in unattended scenarios—such as at night, on holidays, or during extreme weather—enabling rapid deployment and resolution of faults, thereby significantly shortening power outage durations.

2. Ensure that tools are compliant and usable to eliminate the need for on-site emergency repairs and rework

Tool failures, expired tools, and tools damaged by moisture at emergency repair sites are the primary causes of rework and operational delays. The smart tool management cabinet ensures that tools issued from the warehouse are 100% compliant, qualified, and operational through three key mechanisms: periodic calibration alerts, intelligent temperature and humidity maintenance, and the locking of expired tools. The system automatically blocks tools that are past their inspection deadlines, exhibit performance abnormalities, or have failed due to moisture damage, preventing them from being issued for use. This eliminates at the source issues such as rework on emergency repairs, secondary equipment failures, and safety incidents caused by tool problems, ensuring that emergency repair operations are completed successfully on the first attempt and significantly improving fault resolution success rates and operational efficiency.

3. Ensure precise tool matching to eliminate issues such as missing or incorrect tools

For emergency repair tasks involving different voltage levels and fault types, the system can intelligently generate a customized tool list, guiding repair personnel to accurately collect the necessary tools and avoiding issues such as incorrect tool selection, forgotten tools, or excess tools that can result from relying solely on experience. At the same time, the system automatically verifies the completeness of the tool set before it leaves the warehouse, ensuring that no critical tools are missing. This completely eliminates inefficiencies caused by work stoppages on-site or the need to return to the depot to retrieve missing items, effectively reducing the duration of on-site emergency repair operations and improving the efficiency of each fault resolution.

4. Optimize the process of returning materials to inventory and conducting post-operation reviews to ensure the continuous turnover of emergency repair supplies

After a batch of emergency repairs is completed, traditional manual inventory checks upon return to storage are time-consuming and difficult to verify, often resulting in missing or lost tools and haphazard storage—all of which can affect the availability of supplies for the next round of emergency repairs. The smart tool management cabinet enables automatic identification, inventory counting, and reconciliation upon return, quickly verifying the return of emergency repair tools to the warehouse. It automatically traces and assigns accountability for overdue or missing tools, expedites the reorganization of supplies, and ensures rapid turnover and constant availability of emergency repair tools to address continuous and sudden power grid failure repair tasks.
