Wagons are one-sided, though locomotives are dual-sided for flexibility. In contrast, ECP braking uses electronic controls which make it possible to activate air-powered brakes on the cars.
As the brake pipe pressure reduces, the service portion on each car divert air from their reservoirs to their brake cylinders. In which, an APR is added in the circuit compared with the conventional pneumatic brake system, and the pressure can be regulated accurately and independently.
To release the brakes, the engineer charges the brake pipe. The structure improvement of pneumatic brake circuit. This Automatic pneumatic braking braking can cause significant forces to build up between the cars in a train. Therefore, it must ensure the braking pressure and braking time to meet the braking expectations simultaneously, and then it is necessary to take into account the pressure and time deviation.
The wagons are one-sided to suit a rotary tippler. On an ECP-equipped train, the cars are equipped with a Trainline Cable that runs parallel to the brake pipe down the length of the train. Further, since the cars can also send their status to the locomotive at the front, the engineer can monitor the state of the train and know at any given time the braking capabilities available.
Further, since the engineer is only aware of the brake pipe pressure and flow of air into the brake pipe, it is not easy to know the state of the train brakes at any given time. In the case of the Fortescue railway, the new ECP brakes are incompatible in several ways.
Therefore, for the autonomous vehicles, the mechanism and regulation of the brake pressure response characteristics should be understood clearly first, and then the pressure can be controlled accurately through precision control model. In addition, a pneumatic booster valve adds before the tank, the booster valve is parallel combined into the existing system with a diverter valve, and it helps regulate the pressure independently according to the braking requirements and increase the local supply pressure, thereby improving the braking ability and enhancing the system efficiency.
The conventional braking system suffers from many weaknesses; one of which is in the reaction time. Finally, to improve the braking ability under emergency conditions and under pressure defection conditions, and also to ensure the driving safety, a pneumatic booster valve is added before the gas tank.
When the brake pipe and car Automatic pneumatic braking are charged with air, the brakes release. For this APR, it should satisfy the following points: Federal rules limit normal air brake inspection to once every kilometers, but with ECP this increases to kilometres, allowing a coast-to-coast return trip on a single inspection at home base.
Therefore, an automatic pressure regulator APR is added Automatic pneumatic braking the front of the brake chamber to achieve precise brake pressure controlling, thereby achieving differential braking to ensure the requirements of braking stability. AugustRio Tinto railway - entire fleet of iron ore wagons.
Automatic brake circuit for autonomous vehicles In order to adjust the vehicle motion state dynamically by using the pneumatic braking system, the brake chambers should be supplied with differential pressure according to different braking requirements, and then the braking pressure of each wheel can be controlled independently.
This cable is used to supply power to the electronic components installed on the cars. On the other hand, a reasonable braking control strategies and control methods should be developed to achieve precision braking. For example, since all the cars receive the brake command at the same time, the brakes are applied uniformly and instantaneously.
Also with ECP, the brake pipe remains charged during operation. Also, since the brake pipe is typically used for control and supply of air to the cars, if an engineer is not careful, the air supply can be depleted.
A brake pressure-time response of pneumatic braking circuit is simply presented in Figure 4. The ECPB can also apply the brakes on the rearmost wagons, slightly before the brakes on the front wagons are applied, which reduces the shock and noise of the wagons bunching up.
