(54) DEVICE FOR OPERATIONAL CONTROL

In AUTOMATIC CONTROL SYSTEMS, the search registers search for rows 3 and columns 4, control unit 5, the outputs of which are connected to registers 3 and 4, as well as to input unit 6 and information input valves 7. Data input unit 6 is connected to valves 7 and valves By searching for addresses, 8 by specified codes via / C-bit input register 9. The outputs of memory cells 2 are combined in rows and columns: and connected to the comparator unit 10 and the display unit 11. The output of the comparator unit 10 is connected to the counter-adder 12 and the control unit 5, and the input is connected to the valve search 8. The device’s address inputs are connected via an additional input register 13 to address decoder 14 and address decoder 15, and inputs are connected to control unit 5. Address decoders i4 and 15 are connected to registers 3 and 4, respectively. Time converter 16 is connected to counter 17, which through switch 18 is connected to input unit 6. The second input of switch 18 is connected to control unit 5. Each storage cell .2 has three inputs, of which two are search for X and Y coordinates and one / C-bit input connected with information entry gates 7. The memory cell of the scoreboard (see FIG. 2) consists of / (- bit register 19, gates 20, element AND 21, element OR 22, decoder 23, element OR 24 and match element 25. The input of the address device of the object under monitoring 26 (see Fig. 1) is connected to the unit control 5, and the output - to the additional input register 13. The device can be used as a device for monitoring technological or production processes, state or just equipment, operational control in the control system, in the field of transport management, and supply, for control the progress of work on networks, as well as to display the conversion of information of optimal planning tasks (assignment tasks, equipment loading, maximum flow, etc.). As an example, consider the process of controlling the release of cars to a line in a large motor transport enterprise. In this case, a plan for releasing cars to the line is entered into the device from a punched tape. The plan shows the car’s garage number and the planned time to go to the line. Information about the actual release of autos-Znley is entered into the device from the sensors of the address of the object being monitored. At the same time, from the sensor: time, the current time of day is entered, which is compared with the planned breathing time of the aircraft, and when detecting deviations, the garage numbers of the cars are output by the display unit. At the request of the dispatcher, the number of cars that have entered the line in the section of the columns and at the plant as a whole at a given point in time can be displayed. 5 14 All the listed tasks can be presented in the form of a matrix in which the indicators can have different values 1: the amount of work of the network schedule, the distance or cost of transportation in the transportation task, the amount of productivity in the assignment problem; technical condition, presence or absence of vehicles, equipment, etc. The device provides the possibility of obtaining operational reports by calculating indicators by their characteristics, as well as by rows and columns. The device works as follows. In the mode of recording indices (state ngy), registers 3 and 4 start to switch to the cell of the board with signals from block 5, and its indicators must be represented as a direct matrix, first in register 3 it is set to state "1 first bit and then all of the first to the last bits of the register 4 are switched alternately. In time with each switch, the signal from block 5 opens the valves 7, and the code of the indicator stored in register 9 is entered into the appropriate cell. Switching unit 5 is carried out by a signal from data input unit 6 simultaneously with sending a new indicator to register 9. Then in register 3 in "1 a second bit is set and information is similarly entered into the second column and so on up to the last column. When entering information with a simultaneous transposition of the matrix of indicators, it is first set to "1 first register bit 4 and alternately starts switching the register from the first to the last bit. It is then set to "1 second register bit 4, and so on, until the matrix of indicators is completely filled, which will be transposed with respect to the original one. To record the actual performance of the plan from the address generator of the controlled object 26, the signal from the control unit 5 informs the additional register of the a-information 13, and then through the decoders 14 and 15 in registers 3 and 4. Thus, the address of the storage cell 2 is selected, in which the planned information is stored. Simultaneously from the time signal generator 16, through the counter 17 and the switch 18, which are opened by the signal from the control unit 5, the current time is entered into the input unit 6 and is rewritten into the storage cell 2 at the selected address. The memory cell 2 works as follows: "1 from X to the Y-th coordinate enters the signal of the indicator, which through the element OR 22 is fed to the third input of the element 21, the output of which opens the valves 20 and the code of the indicator is entered into / (- bit register 19. The output register and 19 through the decoder 23 is connected to a bulletin board, r / e is mapped to an index value in the decimal system.

Register bits 19 with K.-T to, in which information about the actual execution of the plan is stored through the OR element 24, are connected to the input of the coincidence element 25. At the time of the signals "1 with X and Y-th coordinate connected to two other inputs match element 25, and if there is nonzero information in the bits from K-T to K-th register 19, the output of the match element 25 generates a signal that is fed to the input of the comparator unit 10 and blocks the comparison operation. In the address search mode by the indicator that is in the data input block 6, the command of the latter opens the valves 8 and the search registers of the rows 3 and columns 4 are started, and a constant signal is sent to the transfer bus from the block 7.

Therefore, when the outputs of registers 3 and 4 (i.e., A and Y coordinate i coincide on any of cells 2, its code is entered into comparison unit 10 and if this code coincides with the specified code, the code enters the counter-adder 12 and is displayed on the display unit 11 Simultaneously from the output of the block, a command is sent to block 5 to stop the search for the cell number. To monitor the time of work from the time signal generator 16, through the counter 17 and the switch 18, which are opened by a signal from the block 5, the current time is entered in the input unit 6. Then The search for an address by indicator is performed. In this case, the indicator is the current time.If information on the actual execution of the plan is entered in memory cell 2, such a cell is excluded from consideration in the address search mode by indicator, which is provided by the arrival of signals from the coincidence elements. in comparison unit 10.

If it is necessary to sum up the value of any indicator in rows or columns, then work in this mode is carried out similarly to the address search mode by indicator, but the communication of the output of block 10 with the input of block 5 is disabled. In this mode, both algebraic summation of the indicator and and counting the number of a given index.

As in the mode of recording indicators, so

and in the mode of searching for addresses by indicator and summation of indicators, data can be entered continuously from punched tape into data input unit 6, or directly from the output of electronic computational masking. In addition, manual mode is provided when control is exercised by manual control.
