In the power inspection operation, the intrinsically safe explosion-proof handheld terminal has built a full-process safety assurance system from "inspection" to "emergency repair" through its intrinsically safe design and intelligent functions, which is specifically reflected in the following core dimensions：
1. Intrinsically safe design: Addressing the pain points of high-risk environments
Explosion-proof certification and electrical safety: Adopt intrinsically safe circuit design (such as Ex ib IIC T4 Gb certification) to ensure that the spark/heat effect generated by the equipment during normal operation, failure or abnormal conditions is not enough to ignite explosive gases (such as methane, hydrogen). For example, in flammable and explosive scenarios such as substations and around oil and gas pipelines, the terminal can safely complete operations such as data collection and video calls, avoiding the risk of explosions caused by static electricity and short circuits in traditional non-explosion-proof equipment.
Ability to withstand harsh environments: It has passed IP68 dustproof and waterproof, high and low temperature resistance (-40℃~80℃), impact resistance and other tests, adapting to the extreme conditions of outdoor inspections and ensuring the reliability of the equipment itself.
2. Inspection stage: Intelligence improves efficiency and accuracy
Precise positioning and trajectory tracking: Integrated Beidou/GPS dual-mode positioning module can upload the location, trajectory and arrival time of inspection personnel in real time. Managers can monitor inspection coverage to avoid missed inspections and wrong inspections. For example, through the electronic fence function, the system can automatically remind inspection personnel to enter dangerous areas or deviate from preset routes.
Data collection automation: Supports QR code/RFID tag scanning, infrared temperature measurement, gas concentration detection (such as combustible gas, hydrogen sulfide), partial discharge detection and other functions, automatically records equipment temperature, humidity, vibration and other parameters, and synchronizes them to the background system. Compared with traditional paper records, data is more accurate and traceable.
Real-time communication and collaboration: Through 4G/5G/Wi-Fi or Mesh ad hoc network, real-time audio and video calls and data transmission between the inspection site and the backend are realized. For example, when inspection personnel discover an abnormality in the equipment, they can immediately upload on-site photos, videos and detection data, and background experts can remotely guide or dispatch emergency repair resources.
3. Emergency repair stage: Quick response and security control
Fault diagnosis and decision support: The terminal has a built-in expert knowledge base and AI algorithm, which can conduct preliminary analysis of inspection data (such as temperature anomalies and partial discharge signals) and automatically generate fault level assessment and processing suggestions. For example, the system can predict fault development trends based on equipment historical data and environmental parameters, and provide early warning of potential risks.
Safe work instructions: Through the AR or video guidance function, real-time visual guidance of equipment disassembly and maintenance steps is provided to emergency repair personnel to avoid misoperations leading to secondary accidents. At the same time, the terminal can be linked to smart helmets, gas detectors and other equipment to monitor physiological indicators such as gas concentration and personnel heart rate at the emergency repair site in real time to ensure operational safety.
Emergency Communications and Dispatch: In remote areas or signal blind areas, terminals can maintain contact with the rear through satellite communications or ad hoc networks to ensure timely transmission of emergency repair instructions, safety warnings and other information.
4. Full-process safety assurance system
Data closed-loop management: Inspection data, emergency repair records, equipment ledgers and other information are integrated into the power asset management platform to realize the full-process digital management of "inspection - discovery - reporting - analysis - emergency repair - verification". Through big data analysis, high-frequency fault points can be identified, inspection routes can be optimized, and operation and maintenance efficiency can be improved.
Safety training and assessment: The terminal can integrate a training module to improve the safety awareness and skill level of inspection personnel through simulated operations, case studies and other functions. At the same time, the system can record personnel's operating behaviors for safety assessment and responsibility tracing.
Compliance and standards compliance: Comply with national and industry explosion-proof standards (such as GB 3836 series) and power industry safety regulations to ensure that the equipment is used within the framework of laws and regulations and reduce corporate compliance risks.
Intrinsically safe and explosion-proof handheld terminals realize the transformation of power inspection from "passive response" to "active prevention" through intrinsically safe design, intelligent functions and full-process digital management. It not only improves the efficiency and accuracy of inspection, but also builds a safety guarantee system covering the entire "inspection-repair" chain, providing reliable technical support for high-risk operation scenarios in the power industry.
