  • the Help System makes available to all equipment connected to the internal train network the information on the positioning and status of the train that the positioning module calculates.
  • the transmission of the position and other state variables of the train to the Command Post of the railway system uses a simple expert system that determines the cadence with which this information is transmitted.
  • the purpose of this expert system is, fundamentally, to vary the frequency of transmission of the information. Higher frequency when the position is changing rapidly or determines an event and lower frequency when the train is stopped and its position does not change. This means a saving in the cost of transmission and in the density of information traffic.
  • This adaptation of the transmission frequency to the Traffic circumstances are determined by an expert in the operation of railway traffic. Said expert establishes a flexible set of rules that set the various conditions in which the status information must be transmitted. These rules are created using the Remote Configurator of the Help System and transmitted to the Help System.
  • the expert system based on the conditions set in these rules and its comparison with the circumstances of its surroundings (elapsed time, distance traveled, absolute time, absolute position and train status: stopped, running, with open doors, etc. ) instructs the communications module to send the train positioning and status information when the conditions of the rules are met.
