2General Characteristics

The MIREL RM2 Integrated On-Board System integrates the function of DRV speedometer, on-board

recording device, as well as protection device of vigilance monitoring. Basic functions are measurement of

actual rolling stock driving speed, measurement of covered distance, evaluation of movement direction,

calculation and indication of movement speed at driver cabs as well as record generation of mentioned

quantities. Beyond mentioned quantities, the system carries out a record of actual values for other safety-

related, operating and technology quantities from DRV, dependent on independent time- and distance

scale in real time, in extent based on system configuration and installation method applied for a given type

of rail vehicle. The system provides safety-relevant as well as safety-irrelevant output signals, dependent

on measured actual speed and covered distance of the rail vehicle.

The MIREL RM2 Integrated On-Board System carried out vigilance monitoring of the driver, or DRV staff,

eventually.

The MIREL RM2 Integrated On-Board System fulfils the function of operating and technology data transfer

via the GSM gateway to a remote server. Apart from that, the system provides for determination and regis-

tration of DRV position and for time synchronization based on GPS.

The actual extent of MIREL RM2 Integrated On-Board System functional properties is determined by sys-

tem configuration for specific type application case.

The MIREL RM2 Integrated On-Board System can be operated on rail vehicles of all types of traction, on

steering rail vehicles, work machines and similar vehicles.

Power supply of MIREL RM2 Integrated On-Board System is provided from rail vehicle battery source.

4System Diagnostics

Diagnostics of MIREL RM2 Integrated On-Board System features four levels

One-time diagnostic inspection

Continuous diagnostic inspection

Functional test

Prophylactic inspection

Levels D1 and D2 run automatically after switching on the MIREL RM2 Integrated On-Board System. Staff

intervention of staff is required for performance of D1 diagnostic test if the MIREL RM2 Integrated On-

Board System is in modification with vigilance monitoring function. In case of MIREL RM2 Integrated On-

Board System failure detection when running the D1 and D2 test, the staff is notified about such fact and

MIREL RM2 Integrated On-Board System switches itself to a safe status dependent on character of the

detected failure. If the detected failure doesn´t allow further operation of the integrated on-board system, a

measure takes place to prohibit further DRV operation. Based on character of the detected failure, an

operational system repair (S1), eventually a system service repair (S2) must be carried out.

The functional test (D3) of system is usually carried out by a trained employee of the Operator. During the

functional test, the basic system functionality in all operating functions is inspected. Functionality of input-

output circuits, cooperation with main DRV functional units, as well as functionality of indication elements

and keyboards is inspected. In case of failure detection, an operational system repair (S1), eventually a

system service repair (S2) must be carried out.

The prophylactic inspection (D4) of the system is carried out periodically by the producer of integrated on-

board system, or by an authorized and trained subject. Apart from functional test, an in-depth inspection of

the entire system is carried out. Inspection is carried out in terms of full functionality verification and wear

status. Should a connection failure of integrated on-board system to DRV technology be revealed, an

operational repair (S1) is necessary. When an internal failure of the integrated on-board system is detect-

ed, a service repair (S2) is necessary.

System diagnostics within the framework of D3, D4, S1 a S2 is carried out by means of MIREL MAP soft-

ware, which is started on service-PC. Computer connection is effectuated by means of ATM transfer

module and diagnostics cables. Software description is provided in 974MAP and type of employed diag-

nostics cables in 2521M.

Each person performing the diagnostics of integrated on-board system must be instructed in terms of oc-

cupational safety, traceably trained for this activity and must have a verifiable authorization to carry out

individual levels of system diagnostics.

1987RM2: 180620 11 / 31

4.1 D1 –One-Time Self-Diagnostic Device Inspection

Aim of diagnostics:

A one-time verification of condition, integrity and system functionality during its start-up. Should continuous

system operation exceed 24 hours, the D1 fulfils the function of a daily test.

Performed by:

When the MIREL RM2 Integrated On-Board System is in modification without vigilance inspection, the test

runs autonomously, without necessity of DRV staff intervention. When the MIREL RM2 Integrated On-

Board System is in modification with, intervention of DRV staff is necessary.

Schedule:

With each switching on the MIREL RM2 Integrated On-Board System, repeatedly after 24 hours of system

operation, with postponing option, but must be carried out within 28 hours of permanent system operation.

Test must be carried out within 4h from switching on the MIREL RM2 Integrated On-Board System .

Description:

After switching on, the system carries out a one-time diagnostic test D1, within its framework the commu-

nication functionality on internal central unit bus-bar, functionality of basic unit communication with indica-

tion and identification units, functionality of control elements at driver´s cab are submitted to diagnostics,

as well as functionality of emergency brake EPV and of pressure switch in main brake line.

Should the diagnostics of MIREL RM2 Integrated On-Board System detect a serious system failure, the

system switches itself to a safe status, a serious failure is indicated on indication and identification units of

the system and system is set to a safe status by activation of emergency brake EPV.

List of tests during the one-time diagnostic inspection:

Program integrity check: Central unit modules, as well as identification units IN and indication units ID

calculate separately FLASH memory checksums. They compare them with anticipated values. Should a

FLASH memory error be detected, a system failure is indicated. Device isn´t functionally operative in this

test.

Functionality check of processor operating register –The device performs a recording and reading

test for all processor operating registers in central unit modules as well as in all connected peripherals.

Test is performed with all data bit combinations. Should a failure of operating registers be detected, a

system failure is indicated. Device isn´t functionally operative in this test .

SRAM memories functionality check –The device performs a recording and reading test for the entire

field of processor static RAM in modules at positions ZJ-A, ZJ-B and ZJ-C. Test is performed with all data

bit combinations. Should an error of SRAM memory be detected, a system failure is indicated. Device isn´t

functionally operative in this test.

Check of communication establishment between the block controlling communication on bus-bar

and other central unit modules: The master processor block transmits a SYNC pack necessary for

communication establishment with processor blocks of safe core and with all hubs on communication bus-

bar. If the communication isn´t established within 10s, a system failure is indicated. Device is functional in

this test .

Check of communication establishment between central units and peripherals: The processor block

controlling the communication on central unit´s bus-bar, transmits a SYNC pack necessary for communica-

tion establishment with indication unit IN and identification unit ID. If the communication with indication unit

IN or identification unit ID isn´t established within 10s, a system failure is indicated. Device is functional in

this test.

Functionality check of emergency brake EPV: Within the D1 diagnostic test, the system performs check

of EPV control by both channels.

When switching the MIREL RM2 Integrated On-Board System on, the pressure switch must be in a condi-

tion corresponding the pressure in main brake line under the level of 3,5 bar (condition corresponding with

engaged brakes of DRV).

The one-time diagnostic test D1 is performed with each switching on the system into operation, repeatedly

after 24 hours (daily test) of continuous system operation, with postponing option, but within 28 hours

latest. Repeated start of D1 diagnostic test is carried out automatically, without any staff intervention. Time

1987RM2: 180620 12 / 31

remaining until subsequent daily test is indicated in operating data of the identification unit. Repeated start

of D1 diagnostic test is carried out after meeting the conditions as follows:

◼The test is started again after first stopping of DRV after expiry of 24 hours from last accomplish-

ment of D1 diagnostic test. 15 seconds before the repeated D1 test start, the staff is notified about

this fact by flashing D1 indication on indication unit, as well by audible signal from ZS10 horn at ac-

tive cab. During this interval, the staff has the option, by operating the command button



at indi-

cation unit IN.S, operating the external command pushbutton or by external command on CAN

communication interface, to postpone the repeated start of D1 diagnostic test by another 15

minutes. If D1 isn´t postponed after notification, the D1 diagnostic test is automatically started and

its complete execution is necessary.

◼Shouldn´t DRV achieve zero speed within a time interval of 24 to 28 hours from accomplishment of

last D1 diagnostic test, system detects a serious failure, which leads to system intervention. System

must be subsequently initialized.

The DRV staff is notified about the necessity to perform a repeated diagnostic test D1 by audible signaliza-

tion ZS10.

A component of diagnostic test D1 is functionality check of EPV and simultaneously of emergency brake

pressure switch. System activates twice the opening of emergency brake EPV, which manifests itself by a

brief pressure drop in main brake line. A prerequisite for execution of emergency brake EPV functionality

inspection is an accomplished test of control switch at active cab and releasing of the self-acting pneumat-

ic DRV brake by pressure increase in the main line beyond the level necessary for condition change of

pressure switch. The MIREL RM2 Integrated On-Board System in configuration without indication and

identification unit indicates the process of diagnostic test on board terminals wired to communication inter-

face of MIREL RM2 Integrated On-Board System .

The one-time diagnostic test D1 provides for diagnostics of control elements at DRV cabs wired to MIREL

RM2 Integrated On-Board System in extent required for initialization of MIREL RM2 Integrated On-Board

System . The staff is notified about the necessity of an enforced operation of control elements by indication

of D1 on both IN indication units. For a successful execution of control elements check at cab within the

D1 diagnostic test it is required, that steering switches and the mode selector of MIREL RM2 Integrated

On-Board System achieve the zero position. Subsequent step of diagnostic test D1 is the check of pres-

sure drop in main brake line by means of opening the EPV, which can be carried out only with chosen

active cab. Active cab is selected by respective control switch. In course of D1 test, the staff at active cab

must carry out manoeuvres described below:

◼pressure increase in the main brake line beyond the level necessary for condition change of pres-

sure switch (usually 4,2 bar)

◼the RM2 system opens after 2s the EPV by means of channel M

◼pressure in main brake line occurs and at a level of ca. 3,5 bar the status of pressure switch chang-

es. Based on change of signals from pressure switch, the EPV is closed by channel M

◼pressure increase in the main brake line beyond the level necessary for switching of pressure

switch (usually 4,2 bar)

◼the RM2 system opens after 2s the EPV by means of channel C

◼pressure in main brake line occurs and at a level of usually ca. 3,5 bar the status of pressure switch

changes. Based on change of signals from pressure switch, the EPV is closed by channel C.

Herewith the check of EPV and pressure switch by means of channels M and C is accomplished.

The execution sequence of individual steps of diagnostic test is indicated at indication unit by a 3-dot hori-

zontal line in front of D1 indication. If the line is lit, the respective step hasn´t been carried out. If the re-

spective line extinguishes, the prerequisites for execution of respective step have been met. The meaning

of individual lines is as described below:

Position

Description

4th line from bottom

control switches have reached zero position

3rd line from bottom

mode selectors have reached zero position

2nd line from bottom

in first part of test the pressure has dropped by opening EPV by

means of channel M and the required response of pressure switch

1987RM2: 180620 13 / 31

Position

Description

in the main brake line has occurred

1st line from bottom

in second part of test the pressure has dropped by opening EPV

by means of channel M and the required response of pressure

switch in the main brake line has occurred

After execution of all above-mentioned steps, the D1 indication at indication unit vanishes and system

switches to operation mode.

With a system configuration without Control switch, the step “control switches have reached zero position”

is automatically met.

Execution protocol:

Isn´t compiled.

Handling of detected failures:

After any failure occurrence during the one-time self-diagnostic test, by switching off the power supply for a

time period min. 5 seconds and subsequent powering, the system is re-initialized. If an error is indicated

repeatedly, then such device failure occurred, which excludes further operation. An operational system

repair (S1) is necessary.

1987RM2: 180620 14 / 31

4.2 D2 –Continuous Diagnostic Inspection

Aim of diagnostics:

Continuous verification of condition, integrity and system functionality during its operation.

Performed by:

The MIREL RM2 Integrated On-Board System automatically, without intervention of operating or mainte-

nance staff.

Schedule:

Continually during the operation of MIREL RM2 Integrated On-Board System.

Description:

The MIREL RM2 Integrated On-Board System continuously compares results of processor modules chan-

nels M and C. Should differences be detected between channels, the continuous self-diagnostics detects

system failure and switches the MIREL RM2 Integrated On-Board System to a safe condition. Further

activity, which is continuously submitted to diagnostics by MIREL RM2 Integrated On-Board System, is the

communication of central unit with identification and indication units, based on chosen configurations. In

case of serious communication failure with indication unit of active cab (the cab with control ON), the

MIREL RM2 Integrated On-Board System doesn´t permit further operation. If the communication failure is

detected on identification or indication unit of the inactive cab, further system operation is allowed in re-

stricted extent and the MIREL RM2 Integrated On-Board System requires operational repair.

Tests executed during continuous self-diagnostic inspection:

Test by watchdog circuits –Module processor blocks at positions ZJ-A, ZJ-B and ZJ-C as well as indica-

tion units IN and identification units ID feature a pair of watchdog circuits. Watchdog circuits supervise the

correct activity of processors proper, correct program run, activity of timers and functionality of processor

interruption systems. Watchdog circuits operate with a time baseline of 1,2s, 1,6s and 34,1ms. Upon error

detection, the watchdog circuit causes re-initializing of respective functional module, which subsequently

generates an error message for the entire system.

Communication functionality test –Each unit of MIREL RM2 Integrated On-Board System monitors the

functionality of data communication at RS485 line. In case, that a successful communication fails for a

period longer that 3 seconds for identification and indication units, 5 seconds for LSM and LCM external

modules, the system reports a communication failure with given module.

Speed measurement test –dependent on individual modification, the speed measurement is performed

by a double-channel or quadruple-channel incremental speed sensor. Instantaneous actual velocity is

calculated in M channel from signals A and B and in C channel from signals C and D. Such calculated

velocities are compared between each other and the higher of them is utilized further. If within a time peri-

od of 10s the difference between calculated channel speeds is bigger than 3 km.h-1, as well as in a case,

when one channel evaluates the DRV travel speed as zero one and the other channel evaluates the DRV

travel speed as non-zero for a period of more than 3s, the system indicated an error.

Test of actual movement direction evaluation –like with the speed measurement, the accord of evalu-

ated direction is tested. Should a discrepancy between evaluated directions be detected for 3s, the system

indicates error .

Movement test prior accomplishment of D1 one-time diagnostics

In case of a configuration without vigilance function during DRV movement prior accomplishment of D1

one-time diagnostics, the system indicates error. In case of a configuration with vigilance function during

DRV movement prior accomplishment of D1 one-time diagnostics, the system initiates emergency stop.

Test of EPV upon intervention

With an insufficient or slow pressure drop in main brake line upon intervention, the system indicates error.

Test of power supply and wiring integrity of individual signals from IRC

The integrity of IRC and of individual signal conductors wiring is checked by PC module. Upon detection of

integrity violation, the system indicates error.

Test of decoding and of instruction file instruction execution

The system continuously checks functionality of decoding and of execution of critical sets of instructions. In

case of inconsistency indication, the system indicates error of the respective module.

1987RM2: 180620 15 / 31

Configuration integrity test

Configuration data in FRAM are secured by checksums. In case. When an integrity violation of configura-

tion security is identified, system indicates error.

Data integrity test in FRAM

Data in FRAM are secured by checksums. When an integrity violation of security is identified, system indi-

cates error .

Test of real time clock (RTC) functionality

When a stoppage of real time clock is detected, the system indicates error.

Test of registration functionality

If a failure is detected in the process of registration, the system indicates an error.

Test of processor module restart by supervising circuits of watchdog type

In case of module restart detection by supervising circuits of watchdog type, the system indicates a com-

bined error of respective module.

Execution protocol:

Isn´t compiled.

Handling of detected errors:

After any error occurrence during the continuous self-diagnostic test, by switching off the power supply for

a time period min. 5 seconds and subsequent powering, the system is re-initialized. If an error is indicated

repeatedly, then such emerging device error excludes further operation. An operational system repair (S1)

is necessary.

1987RM2: 180620 16 / 31

4.3 D3 –Functional Test

Aim of diagnostics:

Verification of basic functionality and integrity of operated system. Verification of odometry, system input-

output circuits, readiness of EPV for action, readiness of pressure switch in DRV brake system, functionali-

ty verification of interface to operating staff, as well as real time circuits of the system.

Performed by:

A trained person of MIREL RM2 Integrated On-Board System Operator, or any other traceably authorized

and trained person.

Schedule:

Regularly every 6 months, with a tolerance of 1 month. An execution of D4 prophylactic inspection substi-

tutes the execution of D3 functional test.

In case of unscheduled execution of D3 functional test, a new six-month period starts to run.

First deadline for functional test D3 starts to run with system activation date on DRV.
