Braking installation for a railway train including a plurality of wagons for transporting goods

摘要

A braking installation (1) includes a pneumatic brake pipe (BP) which extends along the train, and wherein the pressure is controlled by a braking control apparatus (BCA) in the locomotive (L), an electrical power supply and communication line (EL) which extends along the train, and which is coupled to an electronic control unit (ECU) in the locomotive (L); and in each wagon (W) or in each group of wagons (W), an electronic module (EM) coupled to the electrical line (EL) through power supply and communication interface devices (I, I1), and further connected to an electro-pneumatic control assembly (EPC) designed for driving pneumatic brake valve means (ELV).

1. Braking installation for a railway train including a locomotive and a plurality of wagons for transporting goods, comprising
a pneumatic brake pipe which extends along the train, and wherein the pressure is controlled by a braking control apparatus in the locomotive, an electrical power supply and communication line which likewise extends along the train, and which is coupled to an electronic control unit in the locomotive; the installation further comprising, in each wagon or in each group of associated wagons: an electronic module coupled to said electrical power supply and communication line through power supply and communication interface means, and further connected to an electro-pneumatic control assembly designed for driving pneumatic brake valve means which are coupled to the pneumatic brake pipe and are adapted to apply to brake cylinders of the wagon or a group of wagons a braking pressure variable in a controlled manner; the electronic module being further connected to electrical sensor means associated with the electro-pneumatic control assembly and/or the brake valve means for acquiring signals or data relating to values or states of predetermined quantities; the interface means comprising electronic processing and control means and transceiver means adapted to allow an exchange of information and/or data with said electronic control unit of the locomotive through said power supply and communication line, for controlling the braking of the wagon or group of wagons; the installation being characterized in that, in each wagon or group of wagons, a local communication network or bus is positioned between the interface means and the electronic module, and additional transceiver means are provided, which are coupled to said electrical power supply and communication line, and which operate in a frequency band which is different from, possibly overlapping but broader than, that of said transceiver means; said processing and control means being designed for driving the additional transceiver means when said transceiver means are active and/or inactive, and for communicating to the electronic control unit of the locomotive information derived from the signals provided by said electrical sensor means to the electronic module and transferred by the electronic module to the interface means through said local communication network or bus.
