Block 18 power supply is connected to the input supply voltage unit 17 line item and is paratory 16 Executive group.
In block 9 storage normative data in digital form presents an invalid state controlled outdoor facilities, as well as signs of inadmissibility commands a train dispatcher or officer on duty at the station.
Invalid States consider, for example, the installation of the train at the closed entrance traffic light; prohibiting travel light; loss of control free arrows; loss of control busy participating in the route of the arrow; the violation of logic employed site; violation of logic liberated area; control the availability of accident moving, etc.
Signs of inadmissibility commands can be considered, for example, the installation of the route through the moving control of the accident; the sending of commercial trains on the stretch, etc.

Forming a database on the status of a group of controlled objects (frame), unit 17 via the communication channels in digital form, and transmits it to the corresponding input of the hardware-software device 2 WKS 1 center. Received hardware-software device 2, the data is passed through the block 6 input block 2 control to one of the inputs of the block 7 comparison to the second input of which receives the data block 9 storage normative data. The comparison results received in block 8 of form a solution. Based on the results of the comparison unit 8 forming solution routes in hardware-software device 2, data about the state of the controlled objects and the appropriate recommendations to the train dispatcher. The data obtained, together with recommendations by means of hardware-software device 2 is displayed on the display 4.
On the basis of the obtained state information of the controlled objects, as well as recommendations received by him train dispatcher manages the outdoor devices. Using the unit 3 train dispatcher generates a control Directive for hardware-software device 2, which in turn, before they are issued for apparatus 16 of the Executive group, transmits them to the block 6 of the input data. With regard to the requirements of normative data block 9 form data for the block 8 is formed is the decision-making.
Unit 8 forming solution 4 in hardware-software device 2 or returns the resolution, or sends the prohibition of issuing the command, specifying the reasons for train dispatcher. Information block 8 is automatically displayed on the display 4.
In case of positive result of a Directive sent through the data transmission channels in the block 17 line item, which converts them into electrical signals for the apparatus 16 of the Executive group. With the validation team for inclusion in the operating status of the arrow 11, the input light 12 or 14 moving unit 15 generates a control and status monitoring of outdoor objects.

SUBSTANCE: invention relates to railroad transport and can be used in safety control systems. Proposed method consists in continuous control over the state of safety systems and/or subsystems. For every change in current variables of actual state of safety system and/or subsystem as well as variables of current state at every preset current time interval, expected magnitudes are forecast via simulation of system/subsystem operation in nearly real time. Variables of real state are compared with expected magnitudes. In case difference in said parametres fall beyond tolerances, system/subsystem is changed over into safe state with minimum efficiency and set of operating functions. Then higher-hierarchy system/subsystem is addressed to receive permission for changing over into the state of higher efficiency and increased set of operating functions. Permission received, the state of system/subsystem is varied to allow maximum efficiency and set of operating functions.
