Study Of The Monitor System For The Working Status Of The Locomotive Braking Unit

The department of railroad brings forward the great target of "high speed, heavy load" to face the challenge of the new economic ages. With the object of high transport ability, the cargo railroad train develops toward the direct of "heavy load" and the traveler railroad train develops toward the direct of "high speed". When we talk about "high speed" or "heavy load", brake cannot but be mentioned. The target will not come true, even with good line or efficient traction, if the problems of brake are not solved well.By now though there are many security measures aiming at the brake system, they all do not monitor the final brake status. This text analyses the principle that the locomotive applies the brake carefully, especially further investigates the unit brake structure, and puts forward a kind of new monitoring method: Through measure whether it is touched between brake shoe and wheel surface , combining locomotive speed signal and the brake valve signal, the text can judge whether it is normal to apply the brake; Through the cartoon way to simulate the real working condition of gas and brake shoe ; The text has succeeded to study for the monitor instrument of the working status of locomotive braking system.The new-type diesel locomotive unit brake monitoring system has madenew progress in many facets, such as the monitor position of sensors, the control way of embedded computer and the way of man-machine exchange, this will play a positive role for popularizing the unit brake operating mode monitoring technology of the locomotive.
