The locking key is included between the output data of one of the control devices of the transmitter and the input of the first communication channel and is connected permissive input to an output control unit. The input of the shaper code data is connected to the output of the blocking key, and the return to the first inputs of the control devices-transmitters, the second inputs of which are connected with the remote control. There is a second communication channel and a linear device, the number of which corresponds to the number of control objects. Inputs linear devices connected to the outputs of the first communication channel, some outputs to the control objects, and other outputs to the inputs of the second communication channel, the output of which is connected with the first input control devices-transmitters.

The invention relates to railway transport, in particular to the means of railway automatics, and is intended for use at different levels when transmitting important information.

Known transmission system responsible teams, based on the simultaneous transmission of video and backup on the monitor screen text support (Germany, journal of Signal und Draht, No. 10, 2000, S. 32-36).

The disadvantage of the system is its complexity and inefficiency that makes it unattractive in the Russian context.

The closest known by its technical essence and the achieved result is selected as a prototype information system for the transmission of critical information containing multi-Adjuster-transmitters that are connected with their outputs to the control unit and the driver code information associated outputs through a blocking key with objects of control inputs control devices-transmitters connected to the outputs of the driver code information and the remote control (see RF patent №2089429, CL 61 L 25/02, publ. 1997).

The disadvantage of this si the data message.

The essence of the invention is expressed in a set of key characteristics, sufficient to achieve provided by the invention technical result, which is expressed in improving traffic safety and efficiency by providing the possibility of confirmation of a sent message.

This technical result is achieved in that the transmission system is responsible for information containing multi-Adjuster-transmitters that are connected with their outputs to the control unit and the driver code information associated outputs through a blocking key with objects of control inputs control devices-transmitters connected to the outputs of the driver code information and remote control, equipped with linear devices, the number of which corresponds to the number of control objects, and the inputs of the respective control objects through a linear device, one of the communication channels and blocking key is connected to the output of one of the generator-transmitter, and outputs linear devices via a second communication channel connected to the inputs of both control devices-transmitters.

A comparison of the claimed technical solution with the prototype allowed Leesa industrially applicable existing technical facilities and meets the criterion of "inventive step", because it is not obvious from the prior art, while the latter does not identify any transformations, characterized by distinctive features of the prototype substantial evidence on the achievement of the technical result.

Thus, the proposed technical solution meets the conditions of patentability of an invention.

Other known technical solutions for a similar purpose with such significant signs the applicant is not found.

The drawing shows a block diagram of the claimed device.

Transmission system responsible information consists of two multi-knobs-transmitters 1 and 2, is connected to the control unit 3 associated with linear devices 4 and two communication channels 5 and 6, as well as driver code information (terminal Manager) 7 through a blocking key 8, and transmitted only from one channel knob transmitter 1 through a blocking key 8, and the reception is carried out both channels knobs-transmitters 1 and 2 character with echo control and termination transfer error echo control.

The outputs of the respective linear devices 4, the number of which corresponds to the number of objects the rum ability to send commands, use the remote control 9 with buttons state data are transmitted on both the input channel control devices-transmitters 1 and 2, the input control devices-transmitters 1 and 2 are connected to the outputs of the driver code information (terminal Manager) 7 and the remote control 9.

The system is as follows.

Referencing the transmitters 1 and 2 operate in cycles with soft sync the same algorithms and generates control information to control unit 3. The control unit 3 includes a blocking key 8, that is, allows data transmission from the transmitter 1 to the driver code information (terminal Manager) 7 and channel 5 only when the coincidence of the control information from the channel knobs-transmitters 1 and 2. If necessary, the responsible supply information in the form of the relevant team Manager it enters from the terminal 7, it comes in referencing the transmitters 1 and 2, which form data to the terminal 7 of the requested command in the first format on the terminal.

Manager, ensuring that the data in the first representation correspond to the input command, presses the first button on the remote control 9, and then referencing the transmitters 1 and 2 send data about the requested command on the terminal 7 are input command, presses the second button on the remote control 9, and then starts the command implementation, i.e. its output to the control objects 10.

The transfer command is on a single line, and the required accuracy is achieved by a double transfer of the same team (preliminary and Executive teams) with confirmation of receipt (acknowledgement) of the pre-command and application of the coding of the transmitted information using a pseudo-random dynamic key. Referencing the transmitters 1 and 2 form the Executive team only if coming from the corresponding linear devices 4 of the receipt of the corresponding sent prior to the command that does not exceed the maximum time interval from filing pre-command to the receipt.

Linear device 4 generates control action on the control object 10 only if coming from the transmitters of the Executive team, consistent with prior command that does not exceed the maximum time interval from receiving the pre-command before receiving the Executive team.

To avoid false prolonged feeding upravlautsa cyclic sending commands by referencing transmitters 1 and 2 with the control in a linear device 4 matching accept commands between themselves and does not exceed the maximum time interval between the received operation commands.

Application of the proposed system provides improved reliability of the transmission of critical information and excludes emergency cases on railroad transport through the fault of automation.
