Smart Plug-in hardware for Variable Messaging Signs (VMS)

VMS use proprietary communication technologies and software for configuration, management and content The aim of ReachVMS is to make the process of deployment and management as seamless as possible by introducing certain layers or adaptors that follow an industry standard

Internet connectivity layer

WiFi and wired-Ethernet are present. A modular approach on both hardware and software layers to enable the base-module to be re-used and appropriate connectivity modules to be plug and playable..

MQTT

Message Queuing Telemetry Transport (MQTT) protocol will be responsible for all communications between to the devices

.

Low level transport

Code + hardware module takes care of connecting with the local VMS and transmitting the data to and from the ReachVMS smart plug-in. It is proposed to be an ethernet port with a local binding to the VMS (LAN).
