Definitions

  • Device for controlling and regulating electrical, electronic or electromechanical Components in rail vehicles with at least one microcomputer in each vehicle, a fault memory and a communication interface, which have at least one transmission path communicates with a control center, are provided, and the control center at least one microcomputer and one interface as well as a non-volatile error memory contains and is set up for abnormal operating behavior of the components Build error messages with an error code by processing incoming data and store in the error memory.
  • Components such as e.g. Air conditioners, blower fans, heaters, Toilet flushes, etc., which are used generally as electrical, electronic or electromechanical components can be called.
  • the primary job of electronic controls is usually electromechanical Systems according to the given guidelines according to their functional purpose control and regulate the running processes according to given criteria.
  • To this Purpose are determined using various sensors, e.g. Temperature sensors, from all parts of the System information determined and supplied to the controller in the form of electrical signals the control processed by, for example, programmed logic, and then the resulting resulting commands from the control system to the components via electromechanical actuators fed to the plant.
  • a control In order to be able to fulfill its primary task, such a control has a high level Level of information about the plant to be controlled. Therefore, there is a common one secondary task of an electronic control in it, with the help of this information and any additional signals that may be added to determine automatically whether in the controlled Electromechanical system malfunctions are present (technical fault diagnosis). Often become Plausibility checks performed, sometimes redundant signals compared, and multiple feedback (existing or specifically intended for diagnostic purposes) from the controlled process used. For example, a faulty sensor can be physically impossible measured values are recognized, a faulty switching element usually by a feedback Manipulated variable, a process out of control based on one or more measured values, that are outside their allowable range.
  • control center capable of diagnosis with the help of logical conclusions from the available ones If information detects that there is an abnormal condition, it generates an error message.
  • the content of such error messages depends on the nature of the error and the faulty one Component, but usually the type and location of the fault are given, often time and date as well as important process values at the time of the error.

  • this error message is visible to the operating personnel can represent, and which differ on the one hand by the technology used (for example signal lamps, numerical displays, text displays, interactive data display devices), on the other hand, by the underlying system philosophy (e.g.
  • a disadvantage of such known devices with central error storage is that that the information collected in the central error memory is only the correct error history as long reflects the system when the components of the system are left the same. In the event of a fault, however, components are usually exchanged; the saved Error messages (as well as any saved statistical data, such as operating hours) however, affect the original component, they are after the exchange for the system is neither applicable nor usable and is usually deleted.
