Description
Construction and design
The GEL 2510 was specially developed for the reliable and exact acquisition of the mileage of carrying axles on rail vehicles.
The maintenance-free and energy self-sufficient sensor obtains the necessary energy from the rotary movement
of the axle and transmits the mileage and wagon data acquired to a mobile terminal using RFID.
The measuring system comprises a magnet assembly that, e.g., is fastened to the pressure plate for the wheel bearing,
and the GEL 2510. The latter is mounted on the exterior on the wheel bearing cover and features a low overall height of
25 mm. Due to the contactless magnetic scanning, the measuring system is mechanically de-coupled from the axle.
GEL 2510 mounted on wheel set bearing cover with magnet assembly mounted underneath
To be able to equip the most common wheel bearing types, 4 housing shapes are available. As a result the GEL 2510
can be integrated into existing wheel sets without the need for design modification.
The fastening screws are protected by the protective caps,
these caps are firmly pressed on after assembly. The protective caps cannot be removed without damaging them, as
a result tampering can be detected at any time.
The odometer GEL 2510 is certified in accordance with
ATEX, ignition protection II 2 G EEx ib IIB T4, and can be used in potentially explosive atmospheres.
The odometer does not contain any wear parts and does not
require a battery, as a consequence it is completely maintenance- free and extremely durable.
Function
The odometer is mounted in the existing wheel set bearing cover such that the active surface on the sensor can reliably
detect the magnetic field from the magnet assembly.
If the wagon is in motion, the magnet rotates with the axle and therefore moves past the odometer's sensor surface.
During this process it induces in the odometer pulses that are counted to acquire the mileage. Along with the mileage,
the odometer registers any temperatures that exceed the stipulated temperature thresholds. In addition, the pulses
provide the necessary energy to operate the odometer. The data acquired is saved in an internal non-volatile memory.
The internal memory can be read or written using a reader while the wagon is stationary.
Programming and data transmission
To program the odometer and to read the data acquired a mobile reader with additional RFID communication modules
is used. The reader, an industrial PDA of type TDS Recon X, is equipped with a touchscreen and keypad and is available as an accessory.
To transmit data, the coil cover on the mobile reader is
placed against the odometer with the wagon stationary. To ensure error-free data transmission, the reader outputs an acoustic warning signal which is muted on correct alignment.
During each transmission all the data are read electronically, an error due to reading or allocating the data incorrectly is
therefore not possible.
The data in the odometer are encrypted to protect them against unauthorised access. They can only be read using
the related reader.
The data transmission and configuration are undertaken using the application software RW2510. The software is installed
on the reader in the factory and makes it possible to read, edit and write data in conjunction with the electronic odometer. Upon request the software can be customised for the
specific customer, e.g. with access restrictions.
The data is transmitted from the reader to the PC via a USB port. The data collected can be further processed using common Office applications, ERP systems or maintenance programs.
