TFDS

The railway truck operation fault dynamic image detection system (TFDS) is a major component of the 5T system and smart systems integration. It comprises of the high precision speed system, the high speed digital image acquisition system, the real-time large-capacity image data processing system, and accurate positioning pattern recognition technology. TFDS allows technical train inspections to shift from a "people-inspected, people-repaired" model to a "machine-inspected, people-repaired" model, which improves train operation quality by taking advantage of the efficiency of a machine-controlled operation instead of relying on man power. This effectively improves inspection quality and transportation efficiency, and ensures that the observation of transportation safety is effectively sustained. The full set of systems is recommended, which can be tailored according to the customer's specific requirements.

System parameters:

1. Applicable train running speed: 0.1 to 500 km/h
2. Velocity error: ± 0.1 km/h (in 0.1 to 500 km/h range)
3. Maximum positioning error: 10 cm (in 0.1 to 500 km/h range)
4. Camera resolution: 1616 × 1232
5. Compensatory light source: xenon lamp (high efficiency, low temperature, long life expectancy)
6. Flash time length: 1 to 2 milliseconds
7. Power: 80w/160w
8. Flash source life span: ≥ 5 million flashes
9. Working environment: -40 °C to 70 °C

System features:

1. System is able to independently distinguish passenger trains
2. Improved TFDS managed by the software platform – Platform operation software is simple to use, all categories of platform accounts can be automatically generated, facilitates in creating a more manageable work load for inspection personnel
3. Automatically adjusted exposure parameters – The image acquisition software can automatically adjust exposure time and gain in response to the external environment every time the train passes through the measurement site. This ensures that the best image quality is produced through adaptability to environmental conditions.
4. Rail edge equipment easily installed – The base is submerged and fixed into the track bed using the same method employed in a caisson installation, need for a shock absorption device is eliminated, simple to install and remove, meets industry standards, accommodates repairs made to the railway
