Description

Technical Field

[0001] This application relates to the field of ship control technology, and in particular to intelligent ship oil valve control circuits, intelligent ship oil valve controllers, and intelligent ships. Background Technology

[0002] Existing oil valve control systems are mainly used in fields such as ships and industrial equipment to control the opening and closing of oil circuits to achieve equipment operation control. This control system typically consists of components such as a heading controller, sensors, and actuators. By detecting the operating status of the equipment and operating commands, it controls the opening degree of the oil valves, thereby regulating the flow and pressure of the oil circuits.

[0003] In existing control systems, when the control circuit malfunctions, the oil valve may fail to receive the correct control signal, resulting in its inability to open or close properly. This is particularly dangerous in ship navigation, as a faulty oil valve can prevent the ship from navigating according to the helmsman's instructions, increasing the risk of accidents. Furthermore, most existing control systems lack redundancy design; if the main control circuit of the oil valve fails, the entire steering gear will malfunction, which can have serious consequences in critical applications, such as the navigation control of fishing vessels. Summary of the Invention

[0007] When the intelligent ship is operating normally, if the programmable controller detects that the steering gear rotation angle is less than a preset value, the programmable controller outputs a backup circuit switching signal to the main / backup switching circuit. After receiving the backup circuit switching signal, the main / backup switching circuit disconnects the contact connected to the main oil valve start circuit and closes the contact connected to the backup oil valve start circuit. The programmable controller then controls the oil valve through the backup oil valve start circuit.

[0008] In one embodiment, the primary / standby switching circuit includes a second electromagnetic contactor, wherein the second electromagnetic contactor includes a normally closed contact and a normally open contact; the normally closed contact is connected to the primary starting circuit of the oil valve, and the normally open contact is connected to the standby starting circuit of the oil valve.

[0009] When the intelligent ship is operating normally, the normally closed contact is closed and the normally open contact is open; when the main / standby switching circuit receives the standby circuit switching signal, the normally closed contact is open and the normally open contact is closed.

[0014] In one embodiment, the control circuit further includes a manual / automatic switching circuit connected between the programmable controller and the primary / standby switching circuit;

[0015] When the manual / automatic switching circuit is disconnected, the course of the intelligent vessel is manually controlled; when the manual / automatic switching circuit is connected, the course of the intelligent vessel is controlled by an intelligent algorithm.

[0016] In one embodiment, the manual / automatic switching circuit includes a first electromagnetic contactor.

[0017] In one embodiment, the control circuit further includes a first freewheeling diode and a second freewheeling diode;

[0024] This application adds a primary / backup switching circuit and an oil valve starting circuit to the main control system of an intelligent ship. Under normal operating conditions, when the programmable controller (PCC) detects that the steering gear rotation angle is less than a preset value, the PCC outputs a backup circuit switching signal to the primary / backup switching circuit. Upon receiving the backup circuit switching signal, the primary / backup switching circuit disconnects the contacts connected to the primary oil valve starting circuit and closes the contacts connected to the backup oil valve starting circuit. The PCC controls the oil valve through the backup oil valve starting circuit. Therefore, even in the event of a failure in the primary oil valve starting circuit, the PCC can still control the oil valve through the backup oil valve starting circuit, ensuring the intelligent ship can navigate normally.

[0034] In existing oil valve control systems, when the control circuit or drive circuit of the oil valve malfunctions, the controller cannot start the oil valve normally, which causes the fishing boat to be unable to navigate according to the driver's operation. Based on the above situation, this application provides an intelligent ship oil valve control circuit, an intelligent ship oil valve controller, and an intelligent ship.

[0035] In a first aspect, embodiments of this application provide an intelligent ship oil valve control circuit, including a programmable controller, a main / standby switching circuit, and an oil valve starting circuit, wherein the oil valve starting circuit includes a main oil valve starting circuit and a standby oil valve starting circuit.

[0036] For details, please refer to the following: Figure 1 The input terminal of the programmable controller is connected to the servo motor rotation angle, and the output terminal is connected to the main / standby switching circuit; the main / standby switching circuit is connected in series between the programmable controller and the oil valve starting circuit; the main oil valve starting circuit and the standby oil valve starting circuit are respectively connected between the main / standby switching circuit and the oil valve.

[0037] In this embodiment, when the intelligent ship is operating normally, if the programmable controller detects that the steering gear rotation angle is less than a preset value, the programmable controller outputs a backup circuit switching signal to the main / backup switching circuit. After receiving the backup circuit switching signal, the main / backup switching circuit disconnects the contact connected to the main oil valve start circuit and closes the contact connected to the backup oil valve start circuit. The programmable controller then controls the oil valve through the backup oil valve start circuit.

[0038] In a preferred embodiment, the control circuit of this embodiment further includes a manual / automatic switching circuit, as detailed in the following reference. Figure 2 The manual / automatic switching circuit is connected between the programmable controller and the primary / standby switching circuit. During operation, when the manual / automatic switching circuit is disconnected, the intelligent ship's course is manually controlled; when the manual / automatic switching circuit is connected, the intelligent ship's course is controlled by an intelligent algorithm.

[0039] To provide a detailed description of the intelligent ship in this embodiment, this embodiment provides... Figure 2 Circuit schematic diagram corresponding to the embodiment. (Reference) Figure 3 In this embodiment, the manual / automatic switching circuit includes a first electromagnetic contactor KA1. An electromagnetic contactor is an electrical control device used for remotely connecting and disconnecting circuits, and for frequently controlling the starting, stopping, forward / reverse rotation, and reverse rotation of electrical equipment such as motors and transformers. An electromagnetic contactor consists of a control coil and multiple switches (also called contacts), and the closing and opening of the contacts is achieved through electromagnetic force. In this embodiment, the first electromagnetic contactor KA1 includes four contacts, which are respectively connected to the four output signal terminals of Siemens.

[0040] In this application, the on / off state of the first electromagnetic contactor KA1 can be manually controlled. Specifically, the first electromagnetic contactor KA1 is connected to a control button, which the ship's operator can operate to switch between automatic and manual control. Specifically, KA1 is disconnected when using manual control and turned on when using automatic control.

[0041] In this embodiment, the primary / backup switching circuit includes a second electromagnetic contactor KA2, which comprises two normally closed contacts and two normally open contacts. The normally closed contacts are connected to the primary oil valve starting circuit (composed of K2 and K3), and the normally open contacts are connected to the backup oil valve starting circuit (composed of K4 and K5). Under normal operating conditions of the intelligent ship, the normally closed contacts are closed and the normally open contacts are open. When the primary / backup switching circuit receives the backup circuit switching signal, the normally closed contacts open and the normally open contacts close.

[0042] refer to Figure 3 The normally closed contacts include a first normally closed contact (1, 9) and a second normally closed contact (2, 10); the normally open contacts include a first normally open contact (7, 11) and a second normally open contact (8, 12); the programmable controller includes a first signal output terminal D0.0, a second signal output terminal D0.1, a third signal output terminal D0.2, a fourth signal output terminal D0.3, a fifth signal output terminal D0.4, and a fifth signal output terminal D0.5.

[0043] In this embodiment, the first signal output terminal is connected to the first main switch via the first normally closed contact; the second signal output terminal is connected to the second main switch via the second normally closed contact; the third signal output terminal is connected to the first standby switch via the first normally open contact; and the fourth signal output terminal is connected to the second standby switch via the second normally open contact. In this embodiment, the main switch and the standby switch can be relays.

[0044] Continue to refer to Figure 3 The main starting circuit for the oil valve includes a first main switch K2 and a second main switch K3. The backup starting circuit for the oil valve includes a first backup switch K4 and a second backup switch K5. The oil valve includes a left-turn oil valve Y1 and a right-turn oil valve Y2. Specifically, the first main switch K2 is connected between the normally closed contact and the left-turn oil valve Y1; the second main switch K3 is connected between the normally closed contact and the right-turn oil valve; the first backup switch K4 is connected between the normally open contact and the left-turn oil valve; and the second backup switch K5 is connected between the normally open contact and the right-turn oil valve.

[0045] In this embodiment of the intelligent ship, during normal operation (i.e., without faults), the KA2 coil is not energized, and the switching of KA2 is controlled by Siemens' signal output terminal D0.4. Specifically, the normally closed contacts (1, 9) and (2, 10) of KA2 are closed, and the normally open contacts (7, 11) and (8, 12) are open. The controller's output points D0.0 and D0.1 control left turn and right turn, respectively. When switching to the standby circuit, the normally open contacts (7, 11) and (8, 12) of KA2 are closed, and the normally closed contacts (1, 9) and (2, 10) are open. The controller's output points D0.2 and D0.3 control left turn and right turn, respectively.

[0046] More specifically, the left turn relay (K2) in normal operation is controlled by D0.0; the right turn relay (K3) in normal operation is controlled by D0.1; the left turn relay (K4) in the switched operation is controlled by D0.2; and the right turn relay (K5) in the switched operation is controlled by D0.3.

[0047] In one embodiment, the control circuit further includes a first freewheeling diode and a second freewheeling diode; wherein the first freewheeling diode is connected in parallel with the left-turn oil valve; the second freewheeling diode is connected in parallel with the right-turn oil valve, the anode of the first freewheeling diode is grounded and the cathode is connected to the main starting circuit of the oil valve, similarly, the anode of the second freewheeling diode is grounded and the cathode is connected to the backup starting circuit of the oil valve. In actual use, controlling the on / off state of the oil valve through PWM wave output will cause a huge reverse voltage to be generated across Y1 and Y2, affecting the service life of other components, thus adding D1 and D2 freewheeling diodes. The presence of the freewheeling diodes allows this part of the current to continue flowing and gradually decrease to zero, thereby avoiding sudden current changes and possible interference.

[0048] In one embodiment, the control circuit further includes an alarm circuit; wherein the alarm circuit is connected to the output terminal of the programmable controller, and when the programmable controller outputs a backup circuit switching signal, it controls the alarm circuit to output an alarm prompt signal, such as an audible and visual signal. Figure 3 The output alarm for the operating status after switching is controlled by signal terminal D0.5.

[0049] Additionally, the decision on whether to activate the oil valve backup start circuit can be made as follows: Based on the deviation between the target angle and the actual angle, determine whether to output left turn D0.0 or right turn D0.1. If the deviation is greater than 0.5 degrees, start the timer and record the initial angle and start time. If the timer is running, calculate the elapsed time. If more than 3 seconds have passed and the actual angle change is less than 3 degrees, output signal D0.4 outputs a backup switching signal to switch KA2, and outputs either the redundant left turn D0.2 or right turn D0.3 depending on whether the current output command is left turn or right turn, while simultaneously outputting the buzzer alarm signal at D0.5. If the timer is not running, all output signals remain FALSE.

[0050] In summary, the intelligent ship oil valve control circuit provided in this application adds a primary / backup switching circuit and an oil valve starting circuit to the main control system of the intelligent ship. Under normal operation of the intelligent ship, when the programmable controller detects that the steering gear rotation angle is less than a preset value, the programmable controller outputs a backup circuit switching signal to the primary / backup switching circuit. Upon receiving the backup circuit switching signal, the primary / backup switching circuit disconnects the contacts connected to the primary oil valve starting circuit and closes the contacts connected to the backup oil valve starting circuit. The programmable controller then controls the oil valve through the backup oil valve starting circuit. Therefore, even in the event of a failure in the primary oil valve starting circuit, the programmable controller can still control the oil valve through the backup oil valve starting circuit, ensuring the intelligent ship can navigate normally.
