The modular engineering system contains interacting controllers (1-3), each of them is connected with the group of peripheral equipment located in one of the complex's zones, which includes transducers, executive devices and announcers; controllers (1-3) are universal and operate using the standard software, and their interfacing with peripheral equipment (10-15) is provided by the address micro-modules (4-9) with microprocessors 33; microprocessors have plug-and-play configuration for dynamic individual event and data processing, their transformation to the unified program code and transmission to the controller (1-3) and for transformation of the unified code of controller (1-3) to the individual commands for peripheral equipment (10-15); the single address space is organized, this provides interfacing of data exchange between peripheral equipment and controllers; and it is possible to register and receive the information about certain events. At the same time the adjustment is simplified, the functional capabilities are extended for optimal system assembling and interaction with ennunciators (transducers) installed on long-distance communication lines; the power supply reliability is improved due to possibility of dynamic switch of system devices to the power-saving mode that allows for devices to use the energy for useful work only, and the devises which is not used during the preset time interval are switched off and switched on later by request; the reliability and accuracy of executive devices control are improved as well. |
