The control point device provides the ability to connect to the block the modes of operation of different types of functional blocks, the set of types of which and the total number are determined depending on the volume and types of information.

A disadvantage of the known device of the control room of the telemechanic system is the necessity of forming direct (radial) communication channels between the control point and each controlled point, which complicates and increases the cost of the system.

The purpose of the invention is to increase the capacity of the system due to the possibility of connecting to the common control point the devices of controlled points through both forward (radial) and transit communication lines.

FIG. 1 shows a block diagram of the device control point of the telemechanic system; in fig. 2a and b are diagrams of possible connections between the control point and controlled points, respectively, for the known and proposed devices.

The control point of the telemechanic system contains a generator of 1 clock pulses, a distributor 2, linear blocks 3 and 4,

connected via communication lines with controlled items (not shown in Fig. 1), information transmission unit 5, information receiving unit b, information output

control point 7, information input of control point 8, unit 9 for changing modes of operation, including counter 10, driver 11, switch 12, register 13 and decoder 14.

FIG. 1, for example, one transmission block 5, one information receiving block 6 and two linear blocks 3 and 4 are shown. In fact, the control center device may include a different number of linear blocks, as well as different types of transmission and reception blocks, the number and type of which correspond to the required set of types and amount of information transmitted and received 2.

FIG. 2a shows a connection diagram in a known remote control system between control point 15 and control points 16-18. Only direct (radial) communication lines (LAN) can be used in the system. FIG. 26, as an example, one of the possible options for connecting control point 19 with controlled points 20-27 using the proposed control center device is given. Here, the total cost of establishing communication channels is reduced by using not only radial (connection between 19-27), but also transit lines for controlled items 21-26.

The number of transist links may be more than one (in the example shown, a three-link transit line is used for the connection of points 19 and 24).

Consider the operation of the control unit device shown in FIG. one.

For the transmission and reception of information from controlled points (not shown in Fig. 1), line units 3 and 4 are included in the control room device. Communication with controlled points is via radial or transit lines.

The information from the communication line is entered into the operation mode block 9 after detecting the address of the active linear unit. The addresses of the blocks are set by the counter 10, which in the intervals between the input-output of data on the signal "1 from the first output of the distributor 2" is transferred to the sequential counting mode. Each position of the counter 10 by the former 11 is converted into a positional code, which through the switch 12 (the purpose of which is described further in the text) is applied to the address ranges of all blocks: the fifth inputs of the linear blocks 3 and 4, the fourth inputs of the functional blocks of the transfer 5 and the reception 6 of information. Simultaneously to the second inputs of the linear units and. the third input of the information transmission unit is provided with a signal "1 from the first output of the distributor 2, which is interpreted as a ready interrogation signal. If by the moment the address signal and readiness survey signal were sent to the block, the block prepared the information for transmission, the output bus of the communication request — the third output of the linear blocks and the second output of the information transfer unit — generates a signal "1 arriving at the second input of the distributor 2. This blocks Continuing sequential counting for counter 10.

Let us now consider the data entry mode from block 5. Information in block 5 is entered from the information input of control point 8 from a communication unit with a computer or from a controller (shield). The information entered includes the address of the controlled point-recipient and the information package itself. The sequential code from block 5, gated by signals from generator 1, from the first output of block 5 is sent to the second input of the shift register. At the moment when the address of the controlled point is entered in the shift register (i.e., a parallel address code is formed at its second output), the signal "1 is generated at the second output of the distributor 2. By this signal, the address of the controlled point entering from exit 13 to its second entrance. At the first output of register 13, a sequential code is formed, repeating the code from block 5, but delayed by the time of input and analysis of the code of the address of the controlled point. This code is entered through the first input into the encoder - decoder 14, which, by passing it to the second information output, simultaneously enters it into the encoder. The type of encoder is determined by the information protection method used. For example, when using a cyclic security code, the encoder is a shift register with feedback links including modulo-2 adders. The number and locations of the feedback links are determined by the form of the generating polynomial, and the number of bits of the encoder shift register is determined by the degree of the generating polynomial 2. The previously addressed information transfer unit 5 remains active for the entire time the information code is output from it, and the output code is entered again the addressed linear unit, since now the counter 10 is set to the position corresponding to the code of the address of the controlled point receiving information received from block 5.

The main distinctive feature of the proposed device is the ability to send (and receive) information from controlled points connected to radial or transit lines of communication.

We will consider the mode of transferring information to a controlled item through a transit

the communication line, in this case, one line unit (3 or 4) must be sent information with the address of all controlled points connected through block 3 or 4 to a single or multi-link transit link. For example, in the first (Fig. 26) multi-link transit link, information should be sent if its recipients are controlled items 20-24. For this, the driver outputs 11, corresponding to the addresses of the monitored items 20-24 (for the example shown in Fig. 26), are combined inside the switch 12. For the group of combined inputs at the output of switch 12, one (group) output is used, which is connected to the address (fifth) input of the line unit (3 or 4) corresponding to the given transit link. The number and composition of groups in the switch corresponds to the actual structure of communications between the control point and controlled points. Note that for information transmitting and receiving units, as well as for linear units connected not with transit, but with radial links, the combination of inputs in switch 12 is not made, and each of these inputs is connected with an individual output. Thus, the inclusion of a tunable switch 12 in the device control unit allows it to fully adapt to the real structure of communications in the system, while remaining within the framework of a unified telemechanics system with a standard information parcel structure. After completion of the input to the linear unit of the main and security codes to the third input of the linear unit from the first output of the encoder-decoder 14, the output data resolution signal is supplied to the communication line. Let us now consider the mode of entering information received from the communication line. The line unit that terminates the data reception is placed in ready mode. In the readiness survey, when the counter 10 is switched to the sequential counting mode, the address signal (from the switch 12 output) B is received alternately on the blocks, followed by the readiness polling signal (from the first distributor output 2). As described earlier, the block addressed and ready for output of information exposes a communication request signal (to the third output of blocks 3 or 4). As a result, the sequential counting mode for counter 10 is blocked, i.e. the block that sent the call request signal remains addressed. Note that the linear units connected to the transit lines are

communications, address signals are sent from the switch group output, i.e., when a position signal is set corresponding to the address of any monitored point associated with a single single or multi-link transit link.

Information from the selected linear block from the second output is sent to the second input of the shift register 13, by which the address part of the package is allocated. The address of the monitored source information point is entered into the counter 10 and, as described above, is addressed to the information receiving unit 6. The serial code from the first output of the shift register 13 is directed to the first input of the encoder - the decoder, which passes the code to the output, enters

0 it to the decoder. The type of decoder is determined by the type of security code. For example, when using a cyclic security code, the decoder structure is identical to the encoder structure described above. Information from

5, the second output of the node 14 is entered through the third input into the addressed block 6. After the input is completed, if the node 14 does not detect errors, the signal "1" is generated at its first output, which, acting on the second input of the block 6, allows the output

0 to the information output of point 7 of the control to the communication unit with the computer and to the controller (shield) of the dispatcher.

The proposed control unit arrangement remains unchanged (with the exception of

5 switch 12) with any arbitrary structure of connections between the control point and controlled points. The application of the proposed device makes it easy to adapt to the real structure.

0 communication lines and, thus, to minimize the costs of the organization of telemechanical communication channels both at the design stage of the system, and at possible changes during operation.

The economic efficiency of the invention is due to the fact that the cost of telemechanical communication channels, especially at large distances between points of the system, is several times higher than the cost of the equipment of the system itself.

The control unit device of the TM-310 telemechanic system is at the same time a basic model.
