<\/h2>\nThis plan provides a **practical deployment scheme** for medium-sized warehouses (approx. 1,000\u20135,000 sqm, dense shelving, diverse goods). It covers sensor selection, placement strategies, 4G network architecture, alarm workflow, maintenance, and cost estimation. The design is based on a multi-modal **fire early warning system**plan\u3002<\/p>\n
<\/h2>\n<\/p>\n
1. Early Detection & Multi-Sensor Fusion**
\nUtilize smoke, temperature, flame, and CO sensors to create a multi-modal fire detection system, enhancing early warning capability.<\/p>\n
2. 4G Wireless Transmission**
\nAvoid complex cabling; 4G industrial gateways provide real-time data transmission, remote monitoring, and alerts, ideal for warehouses without fixed networks.<\/p>\n
3. Hierarchical Alarm and Interlock Actions**
\nLocal audible\/visual alarms + platform alerts + SMS\/phone notifications + optional fire suppression interlocks (power cut-off, valve closure, sprinklers).<\/p>\n
4. Scalable, Maintainable, Remote Upgrade**
\nSupports AI video smoke\/flame recognition, thermal imaging monitoring, and LoRa wireless sensor expansion.<\/p>\n
Core Detection Sensors (Mandatory)<\/p>\n
1. Photoelectric Smoke Sensor<\/p>\n
Function: Detect smoldering fire, a key sensor in the **fire early warning system**.
\nSpecifications: Industrial-grade, dust-resistant, adjustable sensitivity, self-check.
\nPlacement: 1 unit per 200\u2013400 sqm, denser in high-density shelving areas, 30\u201350 cm below the ceiling.
\nResponse Time: 15\u201330 seconds for typical smoke density change.<\/p>\n
2. Temperature Sensor \/ Thermal Detector (Differential + Fixed)<\/p>\n
Function: Detect rapid temperature rise or abnormal high temperature.
\nDifferential type for rapid fire detection; fixed type for sustained high temperature zones.
\nAccuracy: \u00b11\u00b0C.
\nPlacement: 1 per equipment-intensive area or switchgear; 1 per 500 sqm in storage areas.<\/p>\n
Function: Detect open flames quickly, complementing smoke sensors.
\nPlacement: Charging areas, flammable storage zones, near power equipment.
\nField of view: 90\u2013120\u00b0 recommended; use UV+IR detection logic to reduce false alarms.<\/p>\n
Enhanced \/ Optional Sensors<\/p>\n
4. Carbon Monoxide (CO) Sensor** \u2014 early detection of smoldering fire.
\n5. Combustible Gas Sensor (CH\u2084 \/ LPG \/ VOC)** \u2014 for chemical or flammable storage zones.
\n6. PM2.5 \/ PM10 Particulate Matter Sensor** \u2014 auxiliary trend monitoring with smoke\/CO sensors.
\n7. Infrared Thermal Imaging Camera** \u2014 detects hotspots, generates thermal maps, suitable for high-value storage or electrical rooms.
\n8. Arc \/ Acoustic Detection Sensor** \u2014 identifies early-stage electrical fires in switchgear.<\/p>\n
Combined, these sensors form a complete multi-modal **fire early warning system**.<\/p>\n
