BETWEEN various types of monorail systems, control systems monorail occupies a very important role: ensuring the safe and secure operation of the train. Railway companies today are faced with many issues by increasing the use of old kinder in population, increasingly diverse needs of the public to look after aging is increasing among young or old, in addition to the current business environment, train hard and train control systems are also faced with a daunting challenge: (1) Provide,safe, secure transport, (2) Lower equipment costs, (3) More flexibility in meeting transport needs, (4) To support the implementation of a more efficient operation with low signal technician . Why choose a Communication Based Train Control CBTC at monorail in …show more content…

The system integrates equipment mounted on trains with ground-based equipment using wireless communication to collect position information from the train and sent back control signal. This significantly reduces the amount of equipment and facilitate roadside benefits such as high traffic density and the use of a single drive or train without a driver. Another advantage of this system is its use of general purpose 2.4 GHz band, which makes it suitable for different countries and regions. The system has also made strong enough to avoid interference from other wireless users and allow its use in mission-critical situations. For example, Hitachi was selected CBTC system for Chongqing Monorail 3 in China, which started operations in September 2011 (operational in 17km of the 55.6km line), and the installation is being planned. Hitachi draws on this experience to accelerate global business activities in the sector of the railway system. Finally, CBTC allows the operator to efficiently control train acceleration and deceleration to maximize energy …show more content…

Basically, the control unit generates ATP ATP board speed control pattern to the next stop block based land information (stop blocks and G / R signal) received from the roadside logical unit transceiver ATP through ATP. Brake control is then activated by the speed of the train is detected by the techno-pulse generator and sensor. Some of the pattern generated by the speed limit control system is weak brake ATP pattern, the pattern of service breaks, or twist the emergency brake and if any of these patterns is exceeded, the brake command signals to apply the brakes as appropriate for each pattern. Speed train on the system board is controlled by ATP, but trains can also be operated manually between stations at speeds below the speed control pattern is determined by the ATP. In case of emergency, onboard ATP system emergency stop receiving messages via train radio equipment, and issued an order that trips the emergency brake brakes and bring the train
