(54) СИСТЕМА УПРАВЛЕНИЯ СУДОВОЙ МНОГОДВИГАТЕЛЬНОЙ УСТАНОВКИ(54) CONTROL SYSTEM FOR SHIP'S MULTIPLE INSTALLATION

VV

Изобретение относитс к судостроению, в частности к системам управлени судовыми многодвигатепьными установками.This invention relates to shipbuilding, in particular, to ship control systems for multi-engine installations.

Известна ттистема управлени судовой многодвигательной установкой, содержаща датчик и задатник скорости, выходы которых соединены с блоком сравнени , быстродействующий регул тор и логичео кую схему, входы которых св заны с выходом блока сравнени , а выходы соответственно с первым и вторым входами первого переключающего устройства, соединенного своим выходом с первым входом сумматора, задат нк мощности, вход которотмэ подключен к выходу за атчнка скорости, а выход - к второму входу сумматора, св занные своими входами с выходами сумматора исполнительные механизмы двигателей, ограничитель мощности двигателей, первый выход которого соедииев с третьим входом сумматора, а также медленнодействукиций регул тор R блок 1 рм ти, причем выход задатчика ,The known control system of the ship's multi-engine installation contains a sensor and a speed reference, the outputs of which are connected to the comparison unit, a high-speed controller and a logic circuit, the inputs of which are connected to the output of the comparison unit and the outputs respectively of the first and second inputs of the first switching device connected its output to the first input of the adder, set the power input, the input is connected to the output for the speed attribute, and the output to the second input of the adder, connected by its inputs to the outputs of the sum matora actuators of engines, engine power limiter, the first output of which is the connection with the third input of the adder, as well as the slow-acting regulator R block 1 rm ty, and the output of the setpoint generator,

скорости соединен со вторым входом лоч гической схемы 1 ,speed is connected to the second input of the logic circuit 1,

Недостатком этой системы вл етс возможность зат жки переходвых процессов и перерегулировани мощности двигателей , что снижает ресурс работы двигателей и маневренность судна.The disadvantage of this system is the possibility of inching transition processes and re-regulating the power of the engines, which reduces the life of the engines and the maneuverability of the vessel.

Цель изобретени - повышение ресу1 са работы двигателей и повышение ма10 невренности судна.The purpose of the invention is to increase the efficiency of engine operation and increase the ship's neuteness.

Цель достигаетс тем, что система снабжена вторым переключающим устройством , первый вход которого соединен с выходом блока пам ти, второй вход - с The goal is achieved by the fact that the system is equipped with a second switching device, the first input of which is connected to the output of the memory unit, the second input - to

Claims

15 output of the slow acting regulator, the third input - with the output of the comparison unit, the fourth input - with the second output of the engine power limiter; the first output is with the input of the slow-running regulator, the second output is with the input of the memory unit, and the third output is with the third input of the right jumper. 36 In the drawing, a functional diagram of cijcTeMbi is shown. The system contains a setting device 1 and a vessel speed sensor 2, connected to the comparison element 3, a high-speed (proportional) controller 4, a slow-acting (integrated) controller 5, an accumulator 6, the first input of which is connected to the output of the controller 4 through a switch device 7 or through switching devices 7 and 8 with the output of controller 5 or memory block 9.. The control input of the device 7 is connected to the output of the logic block 10, and the control input of the device 8 is connected to the second BbixofiOM of the engine power limiter 11, the first output of which is connected to the third input of the adder 6, the second input of which is connected to the output of the power setpoint 12 . Output adder. 6 through the following lines 13 are connected to the actuators 14. 15. The system works as follows. When increasing the setpoint of the travel speed or external load, the syotem increases the power of the engines. At the same time, before the operation of the limiter 11 to the adder 6, along with the signal from the power setting device 12, the signal is also supplied directly from the controller 5 through the switching device 7, then when the setting of the safety limiter 11 occurs, any of the motor parameters exceeds the set value to operate the switching device 8, with the help of which the output of the comparison element 3 is disconnected from the input of the controller 5, the output of which is disconnected from the outputs of the device 8 and connected to the input of the block 9, the output which is connected to the output of the device 8. Thus, the integration of the speed error signal is stopped, and the output signal of the regulator 5 reached by this time is memorized and then feeds from the input of the adder 6. The proposed system allows the output level to remain unchanged the signal of the integral controller during the operation of the power limiter, thereby & 4 th preventing undesirable fluctuations of the parameters of the engines and, consequently, contributing to the increase of their resource, as well as reducing the time transition process during load shedding and reverse installation, which will increase the ship's maneuverability.
