Smart Parking Integration

Il problema

Car parks run their own guidance and barrier systems, so the city cannot show live space availability across sites or link parking with EV charging.

Panoramica della soluzione

MILESGO gateways collect data from parking guidance and barrier systems (API or Modbus), LoRaWAN wireless sensors, EV chargers (Modbus interface or charging platform API) over Modbus TCP / LoRaWAN, and deliver it to the city IoT platform, third-party platforms (HTTP API), large-screen dashboards (HDMI) as MQTT. Field equipment keeps its own protocol and control logic; integration is done by configuration and point mapping, not custom code.

Typical scope

  • parking guidance and barrier systems (API or Modbus)
  • LoRaWAN wireless sensors
  • EV chargers (Modbus interface or charging platform API)

Protocol path

Modbus TCP / LoRaWAN → MQTT

Implementation checklist for the project manager

  • Where equipment only offers a vendor API or cloud, confirm access rights, data rate and costs with the vendor before design.
  • Charger data comes from each charger’s Modbus interface, its energy meter or the charging platform’s API; confirm what each model exposes (OCPP is not handled by the gateway).
  • Run a LoRaWAN coverage survey and pick the regional band (EU868 / US915 / AU915 / AS923 / KR920 / CN470) before ordering.
  • Keep OT networks segregated and use VPN for remote access instead of opening ports to the internet.
  • Fix a site / asset naming convention before the first site so data from all sites can be compared.
  • Roll out in phases: pilot one site or area, confirm data quality, then replicate.

Project deliverables

  • Signed point table and protocol mapping
  • Gateway configuration files and backups
  • IP address plan and network drawing
  • FAT and SAT test records
  • As-built documentation and operator training

Architettura del sistema

Field layer: parking guidance and barrier systems (API or Modbus), LoRaWAN wireless sensors, EV chargers (Modbus interface or charging platform API), connected over Modbus TCP / LoRaWAN. Edge and integration layer: MILESGO protocol gateways and edge controllers, mounted on DIN rail in existing panels, polling each device, time-stamping values and buffering them locally. Upper layer: the city IoT platform, third-party platforms (HTTP API), large-screen dashboards (HDMI), which receives the data as MQTT. Remote access for maintenance runs over VPN rather than open internet ports.

Fasi di realizzazione

  1. 1

    Site survey and point list

    Inventory devices, protocols, register maps, panel space, power and network paths.

  2. 2

    Design and point table sign-off

    Map every point to the target protocol and system; agree it with the client and the upper-system contractor.

  3. 3

    Configuration and FAT

    Build the gateway configuration off site, simulate it and test against the signed point table.

  4. 4

    Installation and wiring

    Mount gateways on DIN rail, wire RS-485 / I/O / Ethernet, apply the IP plan.

  5. 5

    SAT and alarm tests

    Verify values against local readings, test every alarm and command end to end.

  6. 6

    Handover and support

    Hand over configuration backups, point table and as-built documents; train operators.

Valore per il cliente

  • One view of all subsystems instead of separate vendor consoles
  • Data ready for cloud platforms and analytics
  • Open interfaces (BACnet, Modbus, OPC UA, MQTT, HTTP) avoid lock-in to one vendor
  • Configuration templates reused across sites
