Page 3: Industry Pain Points and System Positioning
1. Core Pain Points in Coal Mine Emergency Rescue (Aligned with Standard Gaps)
- "Three Disruptions" Dilemma: Traditional systems struggle to meet MT/T 1129-2011 Clause 5.6.1 "Base Station to Surface ≥10km" transmission requirements; communication is interrupted after network disconnection
- Insufficient Battery Life and Capacity: Existing mobile stations offer battery life ≤4h (failing to meet Clause 5.6.7 "≥11h including 2h calls"), and support ≤10 connected terminals (below the Clause 5.6.2 "≥18 terminals" requirement)
- Lack of Explosion-proof and Immunity Protection: Some devices are not intrinsically safe (non-compliant with Clause 5.10), and electromagnetic immunity has not passed GB/T 17626.3~5 testing
2. System Positioning and Compliance Objectives
- Core Positioning: Based on MT/T 1129-2011, build a "Surface - Underground - Individual Soldier" three-tier compliant system
- Compliance Objectives:
✅ Transmission distance, battery life, and capacity fully meet Clause 5.6 technical specifications
✅ 100% intrinsically safe underground equipment (compliant with GB 3836.1~4, corresponding to Clause 5.10)
✅ Immunity and reliability meet Clause 5.8 and 5.9 requirements (MTBF≥800h)
