Huabao - HB-A1L

The HB-A1L Slave Electronic Lock is a rugged, Bluetooth-connected slave locking device engineered to deliver Plaspy compatible door security and centralized management for logistics fleets. Designed to pair with a GPS-enabled master lock (HB-A1Lm), the HB-A1L extends anti-theft protection and access control across multi-door vehicles such as oil tanker trucks and multi-door box trucks, while feeding lock status and alarms into the Plaspy platform for unified real-time tracking and telemetry.

Compact, explosion-proof and waterproof, the HB-A1L combines RFID access, tamper and chain-cut detection, and long battery life to secure high-risk cargo in harsh environments. When integrated through the master GPS lock, Plaspy receives timely lock events, low-battery alerts and illegal-unlock notifications alongside vehicle location and fleet management telemetry — enabling operators to act fast and reduce loss.

Key Highlights

• Plaspy compatible: integrates lock status and alarms into Plaspy for centralized real-time tracking and fleet management.
• Bluetooth 4.0PLUS pairing: connects to the HB-A1Lm GPS master over BLE; one master supports up to seven HB-A1L slave locks for multi-door control.
• Rugged and safe: IP67 waterproof rating plus ATEX explosion-proof design for safe use on oil tankers and hazardous cargo vehicles.
• Integrated RFID access: supports ISO/IEC 14443 Type A & B, reading distance up to 10 cm and up to 50 cards for secure operator access logs.
• Tamper protection and alarms: illegal-unlock alarm, chain-cut alarm and magnet sensor to detect unauthorized entry or tampering.
• Long battery life: 2,950 mAh main battery with low-battery alarm and up to ~28 days standby time for reliable anti-theft operation between charges.
• Heavy-duty mechanicals: flame-retardant PC + fiberglass housing and high-traction chain options (30/60/100 cm) with up to 1,000 kg traction.

How It Works with Plaspy

The HB-A1L is a Bluetooth slave lock that forwards door and security events to the HB-A1Lm GPS master. The master device aggregates lock status, RFID access logs and alarm events, attaches location and vehicle telemetry, then pushes that combined data to Plaspy for real-time monitoring, alerts and reporting. This architecture lets Plaspy present a unified view of vehicle location, lock status and security alarms without placing cellular hardware on every slave lock.

• Real-time location and telemetry updates — lock events are correlated with GPS data from the master and displayed in Plaspy.
• Door/lock status and alarms — illegal unlock and chain-cut alarms reported immediately to the platform for anti-theft response.
• RFID access events — operator card reads (ISO/IEC 14443 A & B) are logged and visible in Plaspy for access auditing.
• Battery & health telemetry — main battery level and low-battery alarms are forwarded so maintenance schedules can be managed centrally.
• Remote unlocking — authorized remote unlock commands can be issued from the platform/APP/SMS via the paired master device.
• Bluetooth sensors — the HB-A1L uses BLE for pairing and can operate alongside Bluetooth sensors managed by the master device when needed.
• Combined fleet telemetry — Plaspy can combine lock events with vehicle telemetry such as fuel monitoring, ignition or immobilizer status when those signals are available from the paired GPS master or vehicle systems.

Technical Overview

Use Cases

• Fleet anti-theft protection for oil tanker trucks — ATEX-rated lock and chain-cut alarms integrated with Plaspy alerts for immediate response.
• Multi-door box trucks and refrigerated trailers — one GPS master with multiple HB-A1L slaves secures each access point while Plaspy consolidates status and access logs.
• Access-controlled deliveries — RFID access cards allow authorized drivers to unlock doors; Plaspy records reads for compliance and audit trails.
• High-value cargo monitoring — chain traction and tamper sensors add mechanical security and early warnings to reduce theft and diversion risk.
• Maintenance scheduling and telemetry — battery level and device health forwarded to Plaspy to plan recharging and reduce downtime.

Why Choose This Tracker with Plaspy

Pairing the HB-A1L Slave Electronic Lock with Plaspy gives fleet operators a practical, scalable anti-theft solution that complements GPS-based vehicle tracking and telemetry. The HB-A1L’s rugged IP67 and ATEX-certified design ensures safe operation in hazardous cargo environments, while Bluetooth pairing with a GPS master keeps the slave compact and cost-effective. Plaspy combines lock events, RFID access logs and alarms with vehicle telemetry such as location, fuel status or ignition state (when available from the master or vehicle) to provide actionable insights in real time.

For fleet managers focused on reliability, operational efficiency and security, the HB-A1L delivers proven physical protection (chain strength and cut detection), flexible access control, and long battery life. Integrated through Plaspy, this configuration simplifies fleet management and accelerates incident response without adding cellular hardware to every door — an efficient approach to anti-theft, telemetry-driven operations and scalable fleet security.
