CPU with Serial Links & GPS
EKE-Trainnet® Central Processing Unit with Serial Links and GPS (CPS-GPS) has an integrated GNSS receiver to provide precise location and time data for seamless synchronisation with processed information.
The EKE-Trainnet® CPS-GPS unit supports the development, storage, and execution of applications for controlling and diagnosing on-board systems, making it suitable for developing Train Control and Management Systems or Vehicle Control Units. Additionally, it functions as a Gateway by offering essential interfaces and routing capabilities, enhancing overall system integration.
Key Features
The GNSS function is available for simultaneous GPS and GLONASS or, optionally, GPS and BeiDou. CPS-GPS supports active and passive antennas.
Three programmable isolated SCC channels (RS 485), with an optional fourth channel, are available for asynchronous or bit-synchronous communication with compatible train devices.
A 10/100 Mbit/s full-duplex Ethernet interface enables connection to any Ethernet communication network, typically linking the CPS-GPS to switches or electronic racks. Alternatively, it can connect directly to Ethernet-enabled devices, such as network cameras. The number of Ethernet interfaces can be expanded by using one of the EKE-Trainnet® Ethernet Switches.
The CODESYS® PLC kernel embedded in the CPU acts as the CPU’s operating software. Train management applications
can be developed with the CODESYS® PLC software in order to create the desired control and diagnostic functions of the train. The open platform runs on the Linux Operating Software and supports further software development in C language, either as a CODESYS® extension or on top of the module’s Linux kernel. The PowerPC processor provides enough processing power for demanding applications with 400 MHz core speed and 64 megabytes of 64-bit wide 100 MHz SDRAM.
A USB Host Interface is provided to connect memory sticks or other devices for maintenance purposes. B-type connector is used to protect unattended usage (special tools required).
The EKE-Trainnet® Portable System Tester (PST) interface (usually serial link or Ethernet) enables the use of the PST as well as other tools for event log operations, maintenance, debugging, downloading and application development purposes.
The EKE-Trainnet® CPS-GPS real-time clock is powered by a back-up capacitor and will run for a minimum of 30 days from the time power is no longer applied.
Options
The EKE-Trainnet® CPF-GPS is simply an EKE-Trainnet® CPS-GPS with an extended event logging flash memory (4 GB vs 512 MB). EKE-Trainnet® CPF-GPS can act as a low cost event recorder when limited memory and protection are required. The EKE-Trainnet® CPF-GPS has all the features of the EKE-Trainnet® CPS-GPS.
