Dingjian intrinsically safe explosion-proof PDA terminals have built a "preventive safety" system covering the entire process of high-risk industries through intrinsically safe design, multi-modal sensing, real-time communication and intelligent decision support, and have realized the transformation from passive defense to active prevention and control in chemical industry, oil and gas, mining and other scenarios. The specific protection mechanism is as follows：
1. Intrinsically safe design: Breaking through the usage restrictions in high-risk scenarios
Explosion-proof certification and circuit design
It has passed international explosion-proof certifications such as Ex ib IIC T4 Gb and adopts low-voltage and low-current circuits to ensure that the spark energy generated by the equipment under normal or fault conditions is lower than the minimum ignition energy of explosive gases. It is suitable for high-risk environments such as hydrogen and methane.
Even if the equipment is short-circuited or overloaded, the surface temperature is still lower than the self-ignition point of flammable gas, completely eliminating the risk of explosion.
Industrial grade protective performance
Shell material: Use high-strength carbon fiber composite material or anti-static coated aluminum alloy to withstand extreme temperatures from -40°C to 80°C.
Protection level: IP68/IP69K protection level, suitable for humid, dusty, corrosive gas environments, 30% lighter than traditional explosion-proof equipment, improving portability and operational flexibility.
2. Multi-modal sensing and intelligent early warning: Achieve millisecond response to risks
Real-time monitoring of environment and equipment
Gas detection: Integrate methane, hydrogen sulfide, carbon monoxide and other sensors to monitor the concentration of toxic and harmful gases in real time, automatically alarm when exceeding the threshold and link emergency plans (such as starting the exhaust system and cutting off dangerous sources).
Vibration monitoring: Use spectrum analysis technology to detect equipment vibration anomalies, identify potential mechanical failures, and reduce unplanned downtime.
Leak detection and location
Thermal imaging inspection: Abnormal temperature rises in transformers and line joints were found to provide early warning of equipment overheating hazards.
Personnel safety monitoring
Beidou+UWB dual-mode positioning: Realize centimeter-level trajectory tracking, and combine with the electronic fence function to monitor in real time the behavior of people entering high-risk areas in violation of regulations to reduce the risk of accidents.
3. Real-time communication and remote collaboration: Break down information silos
Multimodal communication capabilities
Supports 5G/4G, Wi-Fi 6, and Bluetooth 5.3 dual-mode communications to ensure real-time data transmission between dangerous areas and the central control room.
Areas without public network signals can achieve two-way communication through Beidou short messages to ensure the return of location data in remote areas.
emergency command coordination
Real-time video and data backhaul: When an accident occurs, the terminal can upload on-site video and sensor data within 5 seconds, support remote expert diagnosis and decision-making, and improve emergency response efficiency by more than 40%.
4. Full-process digital management: Build a closed-loop security system
Standardized inspection process
NFC/RFID tag identification: Quickly associate equipment information to standardize the inspection process and avoid manual verification errors.
AI inspection engine: Dynamically adjust inspection routes and inspection items based on historical data and real-time working conditions to optimize resource allocation.
Data-driven decision support
Inspection data is automatically uploaded to the industrial Internet platform, and combined with big data analysis, equipment health reports are generated to predict maintenance needs.
Supports integration with enterprise ERP and MES systems to build a "perception-analysis-decision-execution" closed-loop system to achieve safety performance visualization and continuous improvement.
Compliance and Risk Management
The built-in safety production regulations library supports the electronic circulation and approval of work permits to ensure that the operation process meets regulatory requirements.
The accident case database and emergency plans are electronic, supporting rapid retrieval and simulation drills to improve emergency response capabilities.
5. Industry application results: Cost reduction, efficiency improvement and safety upgrade
Chemical industry
Real-time monitoring of pipeline pressure and temperature, combined with the AI inspection engine to dynamically adjust routes, predict equipment failures 14 days in advance and avoid unplanned downtime.
Oil and gas industry
In the warehousing process, materials can be accurately positioned and inventoried by scanning electronic labels, improving efficiency by 300%.
Mining industry
Vibration sensors analyze pump health to avoid unplanned downtime.
In underground operations in a coal mine, through personnel positioning and environmental monitoring, the accident response time was shortened by 50% and the rescue efficiency was increased by 30%.
