A method is described for controlling pneumatic pressure by actuating a charge and a discharge valve that vary the pressure, comprising, providing a matrix wherein each cell indicates a time for opening the charge or discharge valve; if the initial pressure value in the volume is less than the target pressure value to be reached, opening the charge valve, decreasing the value of the opening time indicated in the selected cell if the pressure value in the volume exceeds the target pressure value and possibly increasing the value of the time indicated in the selected cell; if the initial pressure value in the volume is greater than the target pressure value, opening the one discharge valve for the time indicated in a selected cell and possibly increasing the time value indicated in the selected cell and possibly decreasing the time value indicated in the selected cell.

Method and system for controlling the pneumatic pressure in a volume

The system provides for the control of a railway train for the transport of goods, comprising a plurality of wagons a master locomotive at the head of the train and one or more slave locomotives distributed along the train. The train is equipped with a pneumatic brake pipe which extends along the whole train. The master locomotive is equipped with a master control system for controlling the train, and the at least one slave locomotive is equipped with a slave control system subordinated to the master control system. The master and slave systems can communicate with each other via a radio channel. Each slave system is designed to control traction apparatuses, apparatuses for controlling the pressure in the brake pipe and apparatuses for applying the emergency brake of the corresponding slave locomotive, and for retransmitting signals indicating the status of these apparatuses of the slave locomotive to the master system.
