Smart Luggage Locker Station Product

Overview

A smart luggage locker station is a rentable storage wall: columns of steel compartments, each door fitted with a networked electronic latch, all supervised by one touchscreen terminal that handles payment and access. The customer never receives a key. A booking exists as a record in the Master Controller, and the door opens when the customer presents the matching PIN or QR code at the Control Terminal.

Stations of this type stand in railway stations, airports, tourist sites, and increasingly on the street as click-and-collect points. A typical installation is four Locker Bank Module modules of six compartments each, mixing sizes from 300 × 450 mm cabin-bag boxes up to 900 mm tall suitcase compartments rated around 30 kg.

Renting and opening

The customer touches the screen, picks a size, and pays at the Payment System group — a dip-style Card Reader or the NFC Pad, with card data encrypted inside the PCI-certified Secure Payment Module before it reaches the application. Transit-station units sometimes retain a Coin Acceptor where card-only operation is not acceptable. The controller assigns a free compartment, the LED Strip flashes above it, the latch releases, and the Receipt Printer cuts a slip carrying the compartment number and a PIN or QR code. Returning customers type the PIN or hold the slip (or their phone) under the QR Scanner; the controller verifies the booking, computes any overstay charge, takes payment, and pulses the door open.

The lock

Each door carries an Electronic Lock Unit built around a hardened Latch Bolt: a slam latch, so the door locks by simply being pushed shut, with a Coil Spring return and no user-operable mechanism on the outside. A 12 V Release Solenoid retracts the bolt for about one second on command. The design is fail-secure — power loss leaves every door locked — which is why the Power Distribution group includes an 12 V Battery with a BMS Board sized to keep releasing doors for at least four hours during an outage.

Supervision is per-compartment. The Lock Board, a small addressable PCB on the RS-485 bus, drives the solenoid through a Power MOSFET and reads two independent switches: the Bolt Switch confirming the bolt is fully thrown, and the magnetic Door Switch reporting door position. The distinction matters — a door that reads closed with the bolt not thrown is a customer who didn't slam it, while a door that opens with no release command is a break-in, and the controller sounds the 100 dB Alarm Siren and pushes an alert upstream.

Control and connectivity

The Main Controller Board is an ARM single-board computer running the rental application: tariff tables, compartment map, booking cache, and the event log. It polls every lock board over the Bus Driver, an isolated RS-485 transceiver that can address up to 200 locks on one twisted pair routed through each bank's Wiring Channel. The LTE Router syncs with the operator's cloud platform, which enables the features that distinguish a smart station from coin lockers: advance booking from an app, remote opening by support staff, dynamic pricing, and fleet-wide occupancy dashboards. The booking cache lets the station keep renting and opening during network loss, reconciling when the link returns.

An Occupancy Sensor in each compartment — an IR reflective sensor — confirms a bag is actually present. This drives two operational cases: a compartment reported empty after the rental ends can be released immediately for the next customer, and items left past expiry are flagged for staff removal, a security requirement in transport locations where abandoned bags trigger alarms.

Structure

The compartments are 1.2–1.5 mm powder-coated steel with Sheet Metal Panel dividers; doors hang on Door Hinge units rated for 100,000 cycles and shaped to resist prying at the hinge line. Banks bolt to a 100 mm Plinth Base that levels the station and routes power and bus cabling, and the Tie Frame joins adjacent columns into one structure so no single bank can be tipped or carried off; the Anchor Set fixes the assembly to floor or wall. The terminal itself sits in a 2 mm steel Terminal Housing with tempered glass over the display, and a camera built from an CMOS Image Sensor and Lens Assembly records the terminal approach, tying a face to each transaction the same way ATMs do.
