2. Functions and structure characteristics of main processor unit(MPU)

MPUs are the main processor units of TCMS;

Information is exchanged between train/rolling stock and smart devices via FIP networks;

MPUs receive and process traction/braking command from TCMS as well as field messages;

Hot standby 1+1 redundancy.Standby MPU will take over control in case the main MPU fails;

Two identical MPUs are mounted inside system cabinets;

A complete set of 3U plug-in boards(14 boards) are provided;

Series AGATE LINK 2 standard electronic products are manufactured by ALSTOM;

Standard 3U-21 racks and Easy PlugTM technique are incorporated;

EN 50155-compliant,etc.

3. Function and Structure Characteristics of Remote I/O Module-RIOM

RIOMs are used to acquire,exchange and process field messages;

RIOMs exchange data woth MPUs or ACUs via FIP or MVB bus;

RIOMs are equipped with diodes or gate arrays and able to read/control LV I/O;

Hot standby 1+1 redundancy.Standby RIOM will take over the function of main RIOM in case the main RIOM fails.

Two identical RIOM modules are mounted inside system cabinets;

A complete set of 3U dedicated plug-in boards(16 boards) are provided;

Series AGATE LINK 3X standard electronic products are manufactured by ALSTOM;

Standard 3U-21 racks and Easy PlugTM technique are incorporated;

EN 50155-compliant,etc.

4. Functions and structure characteristics of traction control unit(TCU)

TCUs control and manage AC traction power supply systems-rectifier PMCF and inverter ONIX,and achieve control upon traction motors;

TCUs exchange data with MPUs via FIP bus;

TCUs adopt DSP application technique and have such ability as rapid computation and real-time processing;

"Axle control" traction mode is adopted,6 TCUs control and drive 6 sets of AC traction devices respectively and therefore drive 6 sets of traction motors;

Two TCUs are mounted inside each AC traction cabinet(3 cabinets in total);

A complete set of 3U dedicated plug-in boards(15 boards) are provided;

Series AGATE 3X standard electronic products are manufactured by ALSTOM;

Standard 6U-21 racks and Easy PlugTM technique are incorporated;

EN 50155-compliant,etc.

5. Functions and structure characteristics of auxiliary control unit(ACU)

ACUs control and manage auxiliary choppers and battery chargers,etc;

ACUs exchange data with RIOMs via MVB bus;

DSP,FPGA and other application techniques are incorporated;

Hot standby 1+1 redundancy.Standby ACU will take over control in case the main ACU fails;

Two identical ACU modules are mounted inside auxiliary AC cabinets;

A board combination structure consisting of 1 motherboard and 2 carrier boards are used;

Series AGATE AUX3 standard electronic products are manufactured by ALSTOM;

EN 50155-compliant,etc.

6. Functions and structure characteristics of ariver display unit(DDU)

DDUs are used to display operating states and fault message of locomotives and equipments;

DDUs exchage data with MPUs via FIP network;

Commands may be executed using keyboards;

Information about locomotive operation and faults are downloaded via USB ports;

Two identical DDUs,one main DDU and one auxiliary DDU,are mounted on a driver' s control board;

The main DDU is used to display traction and operating information and the auxiliary DDU is used to display fault and repair information;

Hot standby 1+1 redundancy.Standby DDU will take over control in case the main DDU fails;

Split structure-A DDU is composed of a LCD(10.4”) module and a CPU module;

The CPU is Series AGATE MMI-400 standard electronic products manufactured by ALSTOM;

DDUs are equipped with FIP,USB,EtherNet,RS485 and RS232 interfaces,etc.
