    摘要: A telecontrol system is disclosed whose substations contain a control unit and plug-in interface modules for entering messages or measured values and delivering commands. Both the control unit and the interface modules are equipped with microcomputers and connected via suitable interfaces to a common serial data bus. Because of the presence of the serial data bus, the parallel buses of the microcomputers need not leave the individual modules, which reduces the susceptibility to interference on the buses. In addition, the serial data bus makes it possible to use any form of protection coding, so that individual modules can even be located away from the substation. Each interface module consists of an invariant portion, which is of the same design in all modules, and a problem-adapted portion, whose design depends on the task to be performed.
