Railways Recorders






Recorders/Speedometers

    ATM-RPS3 is a modern electronic device integrated two systems: a train speedometer and a digital data recorder. The unit is designed and manufactured basing on ATM PP Ltd. (ATM) experience in operation of similar system which has been delivered by ATM to Warsaw Subway starting from 1996. The core technology of the system is directly implemented from ATM aviation flight data recorder - a leading product of ATM. Such “aviation” roots of ATM-RSP3 resulting in high reliability and efficiency of the system. ATM-RSP3 is manufactured on the same production line as aviation flight data recorder according to the same quality control systems incl. ISO 9001:2001 and Aviation Production Organization Approval Number PL.21G.0007 issued by EASA (European Aviation Safety Agency). Additionally, for data analysis, MDS software is delivered – it is a special version of aviation FDS software (developed and modified for last 20 years and used for analysis of many aviation crash and accidents) adapted for railroad vehicle purposes. ATM-RPS3 system is designed in “a flexible way” to be easy installed on a wide range of railroad vehicles – new and modified, single and multi-segment units. An open architecture of the system enables to easy integrate ATM-RSP3 unit with other vehicle systems according to a customer request. ATM-RPS3 is delivered in 6 versions and has been installed on the following railroad vehicles: PESA Bydgoszcz: SA133, -SA103, -SA106, -EN81, -EN95, -15WE, -16WE, -121N, 610M NEWAG Nowy Sacz: 14WE Over 150 pcs of ATM-RPS3 have been delivered till the end of 2008.

  • Collecting of data concerning operation of basic vehicle sub-systems
  • Data recording and transformation
- Vehicle technical service:
  • On-line monitoring of real time measured parameters - using a portable lap-top connected to the system or direct monitoring on a cockpit display (only for PIXY display version)
  • Read-out of recorded data and storage them as a lap-top files
  • Analysis of recorded data using MDS software
    • Automatic data de-coding (change of codes for real parameters physical value)
    • Vehicle drive presentation in a time scale, a digital or animated picture of basic cockpit elements, presenting recorded values and position of each element
    • Automatic vehicle drive analysis with detection of a engine-driver faults, technical defects and information about symptoms of potential defects
    • Statistic data calculation
    • Data transfer to data base

System customizing

     ATM-RPS3 it is not a one system, it is a family of systems. Each ATM-RPS3 system (version) is customized to specific customer requirements.

A typical system configuration is as follows: ATM-RP3 acquisition unit, ATM-PW3 velocity display or PIXY display, pressure sensors installed in a braking system, GPS antenna.

     As an option is possible to install: ATM-PW1 velocity analog display. The system can be equipped in GPRS (ATM-RP3GP1) data transmission module and WiFi (ATM-RP3WN1+ WiFi transmitter) wireless data transmission link.

Velocity measurement

Velocity is a most important measured parameter and due to this fact a measuring system is sophisticated and reliably to protect a correct velocity presentation (even if a measuring system is partially damaged). The velocity signal is taking from two independent sensors installed on a different wheel axes. Such configuration ensures a correct measurement in situation when one of the sensors is damaged (for example cable defect). Calculation algorithm of a real velocity takes into consideration such parameters as: a real wheel diameter, a wheel slip and detection of slotted line defects. Velocity measurement resolution (and recording) is 0,125 km/h. Velocity resolution presented on a display is 1 km/h (hysteresis is preserved). Measurement ranges are as follows: 0–125 km/h, 0-160km/h or 0-254km/h.

Sources of information


Wheel rotation sensors

System is integrated to two sensors. It is possible to install hallotrone ATM-CO sensor (CO1 version for NEWAG 14WE, CO2 version for SM42 locomotive) or any other impulse sensor. Sensors can be supplied from ATM-RP3 (12/24VDC) or other sources. In a present configuration, system can operate with sensors equipped in PNP or NPN output . Taking into consideration measuring accuracy, a sensor must generate not less then 22 impulse per one wheel rotation (max. 2048).

Two-state (discrete) inputs

ATM-RP3 acquisition unit is equipped in 32 isolated, galvanic two-state inputs. 8 (eight) of them are prepared for short-time signals such as pushing of dead-man’s handle. Each input (depending on cable connection) can be controlled by delivery of power supply or grounding signal. Typical inputs can be controlled by 24 or 110VDC, but they can be adopted for other voltage, for example 5VDC.


Analog inputs

ATM-RP3 acquisition unit is equipped in 8 analog inputs. One of them steadily monitors power supply voltage. The rest 7 inputs can operate with other voltage or current signals. For a standard configurations those inputs are connected to breaking system pressure sensors supplied by ATM-RP3 unit. It is possible to integrate ATM-PX1 voltage sensor in 0,5MPa or 1MPa, or standard sensors with 4-20mA output.


Integration to other systems

If a railroad vehicle is equipped in a digital control unit of power system, brake system etc.. And it is possible to get data about operation of those systems, ATM-RPS3 unit can be equipped in communication protocol modules for communication with a specific system. The possible options are as follows: RS232C, RS422/485, CAN-OPEN, ETHERNET 10/100. It is possible to execute two communication connections in the same time.


GPS

ATM-RP3 acquisition unit is equipped in GPS sensor. A part of the system is GPS antenna foreseen for roof installation. For GPRS transmission is possible to install one integrated antenna for both systems


Engine-driver identity card

ATM-RPS3 unit is equipped in engine-driver identity card slot – type ATM-IM1. Placing of the card in slot, additionally activated readiness of engine-driver cockpit to operation. Such solution exists on NEWAG 14WE vehicle. .


Data for other systems

ATM-RP3 acquisition unit (depending on version) generates the following data/signal for other systems:

  • velocity higher than 5km/h (relay circuit value to be determined)
  • velocity higher than 10km/h (relay circuit value to be determined)
  • GPS signal (RS422 output)
  • data output for one or two displays (RS422 output)
  • stream data output for all recorded data (for example to passenger information system) (RS422 output)
  •  output for connection of a lap-top (RS232C output)

Data medium

Data are stored on a special adopted CompactFlash cartridges. The cartridge is placing in a slot on the front side of the unit. The slot is locked - the same keys are used for all installed units. Recording time for 2GB cartridge is 4400 hours for single installation and 2200 hours for tandem installation. Of course it is possible to install smaller cartridges: 1GB and 512MB


Catridge slot

Tandem operation

Typical railroad vehicle installation includes one ATM-RP3 unit integrated to two presentation displays (one in each of two engine-driver cockpits). In multi-segment vehicles (for example 4-segmet), taking into consideration a long distance between engine-driver cockpits, is suggested to install two ATM-RP3 units integrated via data exchange and synchronization line. Additionally in such configuration we have a complete redundancy of data registration. Each unit records its own data and second unit data. Such configuration exists on 16WE vehicle manufactured by PESA Bydgoszcz.


ATM-Pw3 display

It is a high-class, fluorescent, digital display for installation in an engine-driver cockpit. The display is equipped in brightness control key and has a special contrast filter and anti-reflection film.


ATM-Pw3 display

The following parameters are presented in an engine-driver cockpit during standard operation mode.



Set of presented parameters depends on operation mode and can be adapted according to individual customer requirements. As an option an analog ATM-PW1 display can be integrated to ATM-PW3 display, or it is possible to integrate any other display selected by customer (controlled via PWM).

Presentation display basing on PIXY company monitor

For latter installations, an engine-driver presentation display is based on INC-62 or INC-72 monitor, manufactured by PIXY company. Such solution enables to present on the display many information in the same time, and (what is more important) to select configuration of presented information. It is not only a typical engine-driver display but as well railroad vehicle maintenance operations display.
