Project background and needs

A road marking solution provider installed reTerminal on its trucks as the central control unit, coordinating paint dispensing and line marking while running its self-developed HMI software.

Keeping in-house software

  • The customer wants the flexibility of a Linux OS.
  • Their HMI software already runs on Raspberry Pi devices.

Needs a Linux device to host existing software.

In-vehicle reliability

  • The existing hardware lacked the stability needed for the application.
  • The control device needs to fit into the truck's existing control box.

Needs stable operation that also fits the in-truck installation space.

Solution and architecture

Device connectivity

reTerminal connects to the truck's control system over Ethernet, exchanging data with sensors, actuators, and control devices.

Operator control

The HMI displays parameters and device status; operators can adjust values and control the start, stop, and speed of spray machines, melters, and conveyors.
