The BoltGATE 20-31 Family is a modular IoT Edge Gateway system, EN50155-certified, which addresses the challenges of the next-generation applications for smart transportation by combining hardware and software for Edge processing and Cloud connectivity. The BoltGATE 20-31 is a stand-alone gateway that can be expanded with a family of Modules that provide a wide range of additional features. The BoltGATE 20-31 and its Expansion Modules can be combined to create a flexible system that suits any use case with the ideal solution.
The BoltGATE 20-31 is based on the Intel® Atom™ E3900 processor, with up to 8GB of ECC RAM, up to 32GB of eMMC, and an optional SSD storage module. Interfaces include up to 3x GbE, 2x USB 3.0, Serial, and Display ports; security features include TPM 2.0. Connectivity capabilities include a carrier pre-certified global LTE cellular, 2.4/5.0GHz Wi-Fi and BLE. A high accuracy GNSS receiver supporting GPS/GLONASS with UDR (Untethered Dead Reckoning) is available in selected configurations. A railway certified power supply offers an ultra-wide input voltage range: 24 to 110VDC, EN50155. The power is distributed by the BoltGATE 20-31 to the Expansion Modules.
The BoltGATE 20-31 includes hardware and software components to support the MVB interface (Duagon chipset, Configurations: ESD+ read-only / ESD+ / EMD read-only / EMD).
The Expansion Modules are:
- BoltAIR 20-31, with up to 3 wireless units and an odometer input;
- BoltSER 20-31, with serial & CAN interfaces;
- BoltIO 20-31, including up to 16 +16 Digital I/Os;
- BoltNET 20-31, with 4 Gigabit Ethernet ports;
- BoltSTOR 20-31, the storage expansion module.
Every module in the BoltGATE 20-31 is fanless and compact, designed to fit in a 3U recess. All modules support -40 to +70°C operating temperature range (EN50155:2017, class OT4, ST1) and can be installed on a DIN-rail, wall-mounted, or assembled in a 19″ rack.
Powered by Eurotech’s IoT Edge Framework, Everyware Software Framework (ESF), the BoltGATE 20-31 provides a fast go-to-market solution for IoT transportation applications such as passenger infotainment and entertainment, train-to-ground communications, and fleet management. The Java-based IoT Edge Framework provides a friendly web-based user interface to visually compose powerful data flows to acquire data from the bus, filter, aggregate and analyze it at the Edge, and publish it to the Cloud though the popular MQTT protocol. Optionally, Everyware Cloud, Eurotech’s IoT Integration Platform, completes this solution by providing data integration to the applications and by offering complete management of the devices deployed in the field.
For customers requiring more configuration flexibility, Eurotech Professional Services offer an extensive number of options for both hardware (additional features, custom front panel/ connectors, branding) and software (customized application images).
