TRAIN CONTROL SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18551627 titled 'TRAIN CONTROL SYSTEM
Simplified Explanation
The patent application describes a system where an on-board device on a train can predict insufficient deceleration and send signals to control the emergency brake unit on another train traveling ahead to ensure safety and prevent accidents.
- The first on-board device on a train controls the emergency brake unit.
- If actual deceleration is insufficient, the device predicts a stop location and sends signals to a ground control device.
- The ground control device relays the signals to a second on-board device on another train to adjust its run curve and control its speed accordingly.
Potential Applications
This technology could be applied in the railway industry to enhance safety measures and prevent collisions between trains by improving communication and control systems.
Problems Solved
1. Preventing accidents due to insufficient deceleration on trains. 2. Enhancing communication between trains to ensure coordinated braking actions.
Benefits
1. Increased safety for passengers and crew. 2. Improved efficiency in train operations. 3. Reduction in the risk of collisions and accidents.
Potential Commercial Applications
"Enhanced Train Communication and Control System for Safety and Efficiency"
Possible Prior Art
There may be existing systems in the railway industry that focus on train communication and control to improve safety and efficiency, but specific prior art related to this exact technology would need to be researched further.

Original Abstract Submitted
A first on-board device installed on a first train controls an emergency brake unit. When it is determined that an actual deceleration value is insufficient in comparison with a predetermined emergency brake reference deceleration value, the first on-board device predicts a first stop location based on the actual deceleration value, and sends, to a ground control device, a first signal indicating insufficient deceleration and a first stop location signal representing the first stop location predicted. The ground control device sends the first signal and the first stop location signal to a second on-board device of a second train traveling ahead of the first train. The second on-board device invalidates a preset first run curve, over a range from a second train location representing an on-track location of the second train to a stop limit location of the second train, and generates a second run curve to control the second train.
