# Coldchain

> The stock record and the temperature record belong together, because a reading you cannot tie to a pallet proves nothing.

A temperature log nobody can tie to a specific pallet proves nothing. The value
is in the binding between the reading and the identity of the stock it was taken
next to. Bind put-away to a chamber and an excursion resolves to a list of
pallets, so a despatch carries the temperature history of the stock on it.

## Workflow

**Receiving** - Inbound at the dock, where the cold chain is most often broken.

1. Read the consignment tag before the door is opened
2. Capture pulp temperature against the consignment identity
3. Weigh in to confirm the quantity delivered against the invoice
4. Accept, reject or accept-under-protest on the spot, with the evidence attached

**Processing** - Storage, with excursions caught as they happen.

1. Log chamber and rack temperature continuously against location
2. Bind every put-away to a chamber, so an excursion names the stock it touched
3. Rotate on first-expiry-first-out from the scanned lot
4. Raise an excursion alert to the operator on the floor

**Dispatching** - Load-out with the chain intact and provable.

1. Pre-cool and verify the vehicle before loading
2. Scan out at the gate against the trip manifest
3. Attach the temperature history to the despatch record
4. Hand the customer a chain of custody they can audit

## What it runs on

- [BLE Gateway](https://iotready.com/hardware/ble-gateway.md): The anchor half of a real-time location system. Wall-mounted, wired for Wi-Fi or Ethernet, and able to raise a local alarm on its own.
- [BLE Wristband Beacon](https://iotready.com/hardware/ble-beacon-wristband.md): A replaceable-band wristband beacon with an SOS button, IP67 sealing and a 16-month battery, for staff, contractor and patient presence tracking.
- [Label Management & Printing Station](https://iotready.com/hardware/label-printer.md): Puts an existing weighing scale and an off-the-shelf barcode printer under one central label catalogue, so the price and the weight on the label are the ones the system holds today.
