Supervision of hazardous chemical transport and cold-chain logistics nationwide continues to intensify. Transportation authorities require positioning devices on special transport vehicles to support temperature collection, fuel circuit monitoring, and external alarm peripherals. Traditional single-trajectory positioning devices can no longer meet industry standards, and market demand for high-end vehicle positioning terminals with RS232/485/TTL expansion interfaces is being rapidly released.

Refrigerated trucks, fuel tankers, and construction machinery operate in complex environments, requiring not only precise BeiDou positioning but also real-time collection of cargo compartment temperature, fuel level data, and equipment operating status. The GT008S waterproof positioning terminal features an expansion serial port that can connect temperature sensors, fuel level sensors, cameras, and iButton identity readers, adapting to full-scenario monitoring of special transport; the IP waterproof body withstands harsh outdoor, construction site, rain, and snow environments, and the 9-90V wide voltage adapts to large construction machinery.

This series supports remote fuel/power cutoff control, SOS emergency alarm, and door magnetic detection. Overspeed, route deviation, and emergency danger situations during hazardous chemical vehicle driving can be pushed as alerts to the management backend at the first opportunity. The communication frequency bands cover domestic 4G full-network access, and European and South American multi-band international versions are also available to meet the needs of cross-border cold-chain transport enterprises. The communication protocol is compatible with the national standard 808 protocol and the general GT06 protocol, and enterprises can integrate their own dispatch platforms to achieve integrated management and control of vehicles, cargo, and personnel.

Industry insiders say the special vehicle supervision market has higher thresholds, and customers place more emphasis on hardware expansion capability, stability, and supporting software services. Source manufacturers with full product lines and deep ODM customization capabilities can provide one-stop solutions for cold-chain, hazardous chemical, and engineering fleets, and high-end multi-function positioning terminals will become the core growth track of the industry in the next three years.
