FIG. 1 is a functional diagram of the control system; on fng. 2 - functional diagram of the polling unit; in fig. 3 - functional diagram of the switching unit of control commands.

The system includes a driver

1 state of objects, to the inputs of which sensors of level 2 and sensors of 3 modes of pump operation are connected through device 4 input and output of information, and another output of device 4 is connected to one of the inputs of control switching unit 5, to other inputs of which corresponding driver outputs are connected 1 directly and through the polling unit 6, one of the outputs of which is connected to one of the inputs of the imaging unit 1. To the other input of the polling unit 6, there is a switch of the key output of the photocircuit 7 critical parameters, whose inputs are connected with sensors

2-level, sensors 8 landing tanker and blocks 9 and 0 control corresponding to the landing and strength of the vessel. The outputs of the unit 5 are connected to the inertial mechanisms 11 and 12 of the pumps and the signal boards 13-15.

On the board 13, the fact of the elimination of the runaway of critical parameters is highlighted, on the board 14 - information on faults in the control line, on the board 15 - recommendations to the operator's action.

Interrogation unit 6 consists of matrix cells 16, control of registers 17 of parameters of strength, heel, trim, draft, general line, and matrix cells 18 of the formation of control commands.

The connection of the matrix cells 16 of the form K) of the control command command registers 17 parameters is organized in such a way that the capacities that can be connected to the process and then the capacities that can be disconnected from the process are polled first.

The matrix cells 16 of the register management. The 17 priority parameters contain a lotus chain, consisting of element 19 AND, connected via element 1 of 20 "delay with one of the inputs of element 21 OR. Output

element 21 OR via element 22 NAND, the second input of lUJToporo is connected to the output; higher control register cells 16, connected with the inverted input of the element 22 AND-NO, the control unit 16 register with the register of the lowest priority parameter with its register 17.

The matrix cells 18 of the formation of the control commands contain the elements 23 AND-NOT.

The outputs of the elements 23 AND-NOT form commands via e, tsmepty 24 OR execute P) The mechanisms 1 1 and 12 for starting and stopping, are connected non-confidentially and with the universal inputs of cells 18, which work with the register of the parameter of lower priority.

The inputs of the elements 23 AND-NOT also connected to the outputs of the shaper 1 state objects.

The control commutating unit 5 consists of switches 25, logic elements 26 and 27, 28, NOT and 29 "Delay. The output of the switch 25 is connected to one of the inputs of the element 26 I, connected by its output through the element 29 "Delay with the signal board 14.

Another input element 26 and connected to the output element 28 NOT, the input of which is connected to one of the inputs of the element 27 And the output of which is connected to the scoreboard 13.

The device works as follows.

From device 4 for each specific case of loading and unloading into the driver

1Objects of objects are entered into final values of the process of cargo operations by levels. Upon landing of the tanker, final values are entered into the former of the critical parameters formaker 7. After selecting the operating mode by switch 25, the device is turned on.

The output signals of sensors 2 levels of sensors 3 modes of operation of pumps and actuators 11 mechanisms of shutters are sent to shaper 1 of the state of objects, and signals from sensors 8 and tanker position on the engine form 7 critical parameters for generating information about the course of the process in mode. automatic control, and on the device 4 input and output information for remote control. Transmitter Signals

2 levels are also received at the input of the former 7 critical parameters for strength. Depending on the specified final values of the process parameters of the cargo operations and the initial state of the executive mechanisms 11 and 12, the signals processed in the object conditioner 1 and enter the polling unit 6, where the process of generating control commands to the actuator 11 of the valves, the actuator 12 pumps using registrar 7 parameters (general line) and matrix cells 18 forming control commands. During the process of cargo operations, in accordance with the final and technical parameters, the parameter register 17 (master line) selects the required matrix cell 18.

The output signals from the matrix cells 18 through the elements 24 OR arrive at the block 5 of the switching control commands, where through the switch 25 they arrive at the performers

mechanisms 11 and 12 (in automatic mode) or on the scoreboard 15 "Recommendations for the leaflet when operating the device in the mode" Advisor. In the event of a fault in the control line, the board 14 lights up by switching on a logical chain consisting of elements 29 "Delay, 26 AND 28 and NOT. Information on the opening and closing of the valves, the start and stop of the pumps is also displayed on the mnemonic of the device 4 for input and output of information.

If the current value of any parameter, for example, strength, exceeds the allowable values, information from the imager .7 critical parameters goes to the scoreboard of the strength control unit 10 and. landing control 9, as well as to the inputs of the matrix cells 16 control registers 17 parameters on the priority of block 6 of the survey.

In the matrix cell 17, the control of register 17 of the parameter is a critical parameter at the input of element 21 OR, and through the element 22 AND-NOT, which simultaneously prohibits the input of element 22 AND-NOT. Of the matrix cell 16 of the lowest priority parameter and the activation of its register 17 meter.

The parameter register 17 carries out the connection of the matrix cell 18 of the formation of control commands to which prohibitive signals are not received from the matrix cell 16 connected to the parameter register

There are higher iriority, and the permitting signals of the conditioner 1 of the objects of the objects can be connected or disconnected. Formed in a matrix cell

The control signal 18 goes simultaneously to the input of block 5 commutation of control commands via elements 24 OR and crosswise to the forbidding inputs of elements 23 of the IS-NOT matrix cells .18 forming control commands connected to registers 17 low-priority pairs 17 .., to the input of the conditioner 1 of the objects, to form a command to turn on the display board 13 "Liquidation of the critical parameter via the element 27 I. After the elimination of the critical parameter, the signal from the input of element 21 OR and the input of element 27 is removed scoreboard 13 "Elimination of the stick out parameter goes critical, a parameter register 17 is reset.

If the recommendation on eliminating the critical parameter is fulfilled by disconnecting the container from the cargo handling process, after time delay on the element 20, signals about the presence of the critical parameter from the generator 7 and about the disconnection of the container from the object state formation unit 1 through the element 19 come to - entry element 21 OR to select the next recommendation.

In case of exceeding the permissible limits simultaneously of several parameters, the choice of recommendations on the parameters of the lowest priority is made after the selection of recommendations on the parameter of the highest priority.
