摘要： As it is known nowadays traditional low frequency cdb equipment are going to be left, for two main reasons: 1. The elimination of insulated joints necessary for confining electric signals within the cdb (this elimination is needed owing to increase in speed of rolling stocks). 2. The presence of new generation locomotives with AC engines that generate on the rails electrical noise with frequencies comparable with the one used in signalling with much higher power that "blind" traditional control systems. In order to face these problems market is suggesting delegating the continuous looping of vehicle signals to GSMR systems (or like this) and adopting for train detection axel counters and Audio Frequency cdb. Both the indicated techniques seem not to be very satisfactory because they have implementation and calibration problems that we intend to overcome with the proposed solution. The solution is based on multi frequencies coded transmission signalling sub system able to operate at low frequency. The system can operate on insulated joint free rails by transmitting control signals trough rail electric noise in SIL4 secure way. The system is cheap, can be easy implemented and assures stronger transmission on longer cdb. The system can be also used to verify rail integrity and other environmental situations on the rail; with some on board equipment modifications the system can be used also for continuous cab signalling repetition (nowadays this is usually made by GSM system).

摘要： One of the fundamental problems of Coded Current Automatic Block (Bacc) system currently in use in about 5000 miles of the RFI (Rete Ferroviaria Italiana) network is the need to use insulated joints to separate various sections of track that are one of the most frequent causes of track breakage. The basic idea of this invention is the separation of the different sections of the line not through galvanic isolation of the rails but through short circuits between the rails. This allows greater consistency along the rails, eliminating completely the delicate isolated joints. Short circuits isolate an electrical circuit that "shifts" in accordance with the movement of the train so that in front of the train there is always a generator present which is able to generate the coded current that is read on-board in accordance with specific railway protocol. The presence of rolling stock can be detected by special current sensors placed in specific places along the rail. The sensors detect the train arrival by means of the short circuits generated by the axles of the train eliminating, at the sensors, the current impressed by generators. Signal transmission to the train remains unchanged compared to previous systems so that no changes in on-board subsystems are required. The achievement of the required safety integrity level is easily obtained because the system has the possibility to re-read what is transmitted to the train It is possible to install the proposed system in specific tracks of the line. The coexistence of tracks traditionally equipped (with isolated joints) and tracks equipped with the new system in the same line allow a gradual transition between the two systems. The system also allows the observation of electrical parameters of the rails, raising alarms in the case of specific types of breakage or damage of the rail.
摘要翻译：目前在RFI（Rete Ferroviaria Italiana）网络大约5000英里内使用的编码电流自动块（Bacc）系统的一个根本问题是需要使用绝缘接头来分离多频段的频段之一造成轨道断裂的原因。本发明的基本思想是不是通过电路隔离导轨而是通过导轨之间的短路分离线路的不同部分。这样可以使轨道更加一致，完全消除了细微的隔离接头。短路隔离根据列车运动“移动”的电路，使得在列车前方始终存在一个发电机，该发电机能够根据特定的铁路产生在车上读取的编码电流协议。机车车辆的存在可以通过放置在轨道的特定位置的特殊电流传感器来检测。传感器通过由列车轴产生的短路来检测列车到达，从而在传感器处消除了发生器所压印的电流。与先前的系统相比，到火车的信号传输保持不变，因此不需要车载子系统的改变。容易获得所需的安全完整性水平的实现，因为系统有可能重新读取传输到列车的内容。可以将所提出的系统安装在线路的特定轨道中。传统上配备（隔离接头）和配备新系统的轨道在同一条线上的共存允许两个系统之间的逐渐过渡。该系统还允许观察轨道的电气参数，在特定类型的断裂或轨道损坏的情况下提高报警。
