Description

Technical Field

[0001] This application relates to the field of emergency stop control technology, specifically to emergency stop control systems and electrical equipment. Background Technology

[0002] In a ship's electrical and propulsion control system, the emergency stop control system serves as a core safety protection mechanism, crucial for ensuring navigational safety. When a ship encounters emergencies such as mechanical failure, fire, or collision, the crew can trigger the emergency stop button to cut off the main power and propulsion system, preventing the accident from escalating.

[0003] Emergency stop control systems in related technologies are prone to false triggering, which can lead to unexpected ship shutdowns and affect navigation safety. Utility Model Content

[0004] The embodiments of this application provide an emergency stop control system and electrical equipment, which can improve the technical problem in the related art where emergency stop control systems are prone to false triggering, thereby causing unexpected ship shutdown and affecting navigation safety.

[0005] In a first aspect, embodiments of this application provide an emergency stop control system, comprising:

[0006] At least two emergency stop circuits, each of which is connected to an emergency stop module;

[0007] A switch module is connected in series with the main power supply circuit, and the switch module is connected to the emergency stop module;

[0008] An emergency stop switch is connected to the at least two emergency stop circuits to allow the emergency stop module to switch between a powered-on state and a powered-off state. When any of the emergency stop modules is in the powered-on state, the emergency stop module causes the switch module to be in a conducting state. When all the emergency stop modules are in the powered-off state, the emergency stop module causes the switch module to disconnect the main power supply circuit.

[0009] In one embodiment, the emergency stop control system further includes an on / off module connected to the emergency stop module, and a switch module connected to the on / off module. The on / off module is used to change the on / off state of the switch module. When any of the emergency stop modules is in the energized state, the emergency stop module causes the on / off module to be in a first state, so that the switch module is in the conducting state. When all the emergency stop modules are in the de-energized state, the emergency stop module causes the on / off module to be in a second state, so that the switch module disconnects the main power supply circuit.

[0010] By adopting the above technical solution, the on / off module and the emergency stop module are connected, allowing the state of the emergency stop module to affect the state of the on / off module, which in turn can change the on / off state of the switch module. Specifically, when any emergency stop module is energized, it puts the on / off module in a first state, which causes the switch module to be in a conducting state, allowing the main power supply circuit to supply power normally. When all emergency stop modules are de-energized, the emergency stop module puts the on / off module in a second state, which causes the switch module to be in a disconnected state, thereby disconnecting the main power supply circuit and cutting off the power supply to the ship's electrical equipment, thus achieving emergency stop control.

[0011] In one embodiment, the switching module is connected between the switch module and the power module. In the first state, the switching module disconnects the switch module and the power module to make the switch module in a conducting state. In the second state, the switching module connects the switch module and the power module to make the switch module in a disconnected state.

[0012] By adopting the above technical solution, when the emergency stop switch is not triggered, even if some emergency stop circuits are disconnected due to a fault, the switching module will be in the first state. At this time, the switching module disconnects the switch module and the power supply module, making the switch module in a conducting state, so that the main power supply circuit can supply power normally. When the emergency stop switch is triggered, all emergency stop circuits are disconnected, and the emergency stop module causes the switching module to be in the second state. At this time, the switching module connects the switch module and the power supply module, making the switch module in a disconnected state, and thus using the switch module to disconnect the main power supply circuit, thereby cutting off the power supply to the ship and other electrical equipment, and realizing emergency stop control.

[0013] In one embodiment, at least two of the emergency stop circuits include a first emergency stop circuit and a second emergency stop circuit, and the emergency stop module includes a first emergency stop module and a second emergency stop module;

[0014] The first emergency stop module includes a first coil and a first auxiliary contact, wherein the first coil is connected in series with the first emergency stop circuit;

[0015] The second emergency stop module includes a second coil and a second auxiliary contact. The second coil is connected in series with the second emergency stop circuit. The first auxiliary contact and the second auxiliary contact are connected in parallel and then in series between the switching module and the power module, so that the switching module can switch between the first state and the second state.

[0016] By adopting the above technical solution, when one of the first emergency stop circuit and the second emergency stop circuit is disconnected due to a fault, the switching module can still maintain connection with the power supply module and remain in the first state, so that the switching module is in the conducting state and the main power supply circuit can maintain power supply. This effectively avoids the situation where the emergency stop control is mistakenly triggered due to a fault in a single emergency stop circuit, and can prevent unexpected shutdowns of electrical equipment such as ships, thus ensuring navigation safety.

[0017] In one embodiment, the switching module includes a third coil and a third auxiliary contact. The first auxiliary contact and the second auxiliary contact are connected in parallel and then in series between the third coil and the power module. The third auxiliary contact is connected in series between the switch module and the power module.

[0018] By adopting the above technical solution, when at least one of the first emergency stop circuit and the second emergency stop circuit is in a conducting state, at least one of the first coil and the second coil is energized, and at least one of the first auxiliary contact and the second auxiliary contact is in a closed state. At this time, the third coil is energized, causing the third auxiliary contact to be in a disconnected state, thus disconnecting the connection between the power supply module and the switch module. The power supply module cannot supply power to the switch module, so the switch module can remain in a conducting state, allowing the main power supply circuit to supply power normally. When both the first emergency stop circuit and the second emergency stop circuit are in a disconnected state, both the first coil and the second coil are de-energized, and both the first auxiliary contact and the second auxiliary contact are in a disconnected state. At this time, the third coil is de-energized, causing the third auxiliary contact to be in a closed state, connecting the power supply module and the switch module. The power supply module supplies power to the switch module, causing the switch module to be in a disconnected state, thus disconnecting the main power supply circuit and realizing emergency stop control. In other words, the main power supply circuit will only be disconnected when the emergency stop switch is manually triggered by the staff, causing both the first and second emergency stop circuits to be in the open state. This effectively avoids the situation where the emergency stop control is accidentally triggered due to a failure of a single emergency stop circuit, and can prevent unexpected shutdowns of electrical equipment such as ships, thus ensuring navigation safety.

[0019] In one embodiment, the first auxiliary contact and the second auxiliary contact are normally open auxiliary contacts, and the third auxiliary contact is a normally closed auxiliary contact.

[0020] By adopting the above technical solution, when one of the first emergency stop circuit and the second emergency stop circuit is broken due to a fault, one of the first coil and the second coil loses power while the other is energized. The power supply module and the third coil can still remain connected, that is, the third coil can still be energized, so that the third auxiliary contact is in the open state, thereby disconnecting the connection between the switch module and the power supply module. The switch module is in the conducting state, and the main power supply circuit can maintain normal power supply. This effectively avoids the situation where the emergency stop control is mistakenly triggered due to the failure of a single emergency stop circuit, and can prevent unexpected shutdowns of electrical equipment such as ships, thus ensuring navigation safety.

[0021] In one embodiment, the on / off module further includes a fourth auxiliary contact, which is a normally open auxiliary contact connected in series with the BMS power supply circuit, so that the BMS power supply circuit can switch between an on state and an off state.

[0022] By adopting the above technical solution, when the emergency stop switch is pressed, both the first and second emergency stop circuits are in an open state, causing the first and second coils to lose power. Consequently, the first and second auxiliary contacts are also in an open state, de-energizing the third coil and opening the fourth auxiliary contact. This disconnects the BMS power supply circuit, stopping power supply to the BMS module and achieving emergency stop control. In other words, pressing the emergency stop switch simultaneously disconnects both the main power supply circuit and the BMS power supply circuit, achieving dual emergency stop control and ensuring the reliability of the emergency stop control.

[0023] In one embodiment, the emergency stop control system further includes a fault alarm element, and the emergency stop module is connected between the power supply module and the fault alarm element. When the emergency stop module is in a powered-on state, the emergency stop module disconnects the power supply module and the fault alarm element. When the emergency stop module is in a powered-off state, the emergency stop module connects the power supply module and the fault alarm element.

[0024] By adopting the above technical solution, when one of the emergency stop circuits is broken due to a fault, the emergency stop module on that emergency stop circuit will be in a de-energized state. The emergency stop module will connect the power supply module and the fault alarm element, causing the fault alarm element to issue an alarm. This allows staff to promptly inspect and repair the emergency stop circuit, enabling real-time online monitoring of the emergency stop circuit and issuing an alarm when the emergency stop circuit is broken due to a fault, thus ensuring the stability of the emergency stop circuit.

[0025] In one embodiment, at least two of the emergency stop circuits include a first emergency stop circuit and a second emergency stop circuit, and the emergency stop module includes a first emergency stop module and a second emergency stop module;

[0026] The first emergency stop module includes a first coil and a fifth auxiliary contact. The first coil is connected in series with the first emergency stop circuit. The second emergency stop module includes a second coil and a sixth auxiliary contact. The fifth auxiliary contact and the sixth auxiliary contact are normally closed auxiliary contacts.

[0027] The second coil is connected in series with the second emergency stop circuit, the fifth auxiliary contact is connected between the power module and the fault alarm element, and the sixth auxiliary contact is connected between the power module and the fault alarm element.

[0028] By adopting the above technical solution, when the first emergency stop circuit or the second emergency stop circuit is broken due to a fault, the first coil or the second coil will be de-energized, causing the fifth auxiliary contact or the sixth auxiliary contact to close, thereby connecting the power module and the fault alarm element. The fault alarm element will issue a fault alarm, allowing staff to repair the faulty circuit in a timely manner.

[0029] Secondly, embodiments of this application provide an electrical equipment such as a ship, including the aforementioned emergency stop control system.

[0030] The beneficial effects of the embodiments of this application are as follows:

[0031] In the embodiments of this application, during normal operation, the emergency stop switch is not triggered, and at least two emergency stop circuits are in a conducting state. Therefore, the emergency stop modules at each emergency stop circuit are energized, and the switch module is in a conducting state, allowing the main power supply circuit to supply power normally. In an emergency, the operator triggers the emergency stop switch, which disconnects all emergency stop circuits. This de-energizes all emergency stop modules, causing the switch module to disconnect the main power supply circuit, thus achieving emergency stop control. Meanwhile, this application is equipped with at least two emergency stop circuits. When only some of the emergency stop circuits are disconnected due to non-human factors, only some emergency stop modules will be in a de-energized state, while the other emergency stop modules will remain energized. As long as any emergency stop module is energized, the switch module will be in a conducting state, meaning the main power supply circuit will not be disconnected. This ensures that the main power supply circuit will only be disconnected when the emergency stop switch is manually triggered by personnel, causing all emergency stop modules to be de-energized. This effectively avoids the situation where emergency stop control is mistakenly triggered due to a fault in a single emergency stop circuit, preventing unexpected shutdowns of electrical equipment such as ships and ensuring navigational safety.

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0038] The following is combined with Figures 1 to 4 This application describes the emergency stop control system and electrical equipment.

[0039] It should be noted that this application can be applied to the field of new energy, such as new energy ships.

[0040] According to the embodiments of the first aspect of this application, see [link / reference]. Figure 1 and Figure 4The emergency stop control system includes a switch module 3, an emergency stop switch 5, and at least two emergency stop circuits 1. Each emergency stop circuit 1 is connected to an emergency stop module 2. The switch module 3 is connected in series with the main power supply circuit 4. The switch module 3 is connected to the emergency stop module 2. The emergency stop switch 5 is connected to at least two emergency stop circuits 1 so that the emergency stop module 2 can switch between a energized state and a de-energized state. When any emergency stop module 2 is energized, the emergency stop module 2 causes the switch module 3 to be in a conducting state. When all emergency stop modules 2 are de-energized, the emergency stop module 2 causes the switch module 3 to disconnect the main power supply circuit 4.

[0041] According to the emergency stop control system of this application embodiment, during normal operation, the emergency stop switch 5 is not triggered, and at least two emergency stop circuits 1 are in a conducting state. Therefore, the emergency stop modules 2 at each emergency stop circuit 1 are energized, and the switch module 3 is in a conducting state, allowing the main power supply circuit 4 to supply power normally. In an emergency, when an operator triggers the emergency stop switch 5, the switch 5 disconnects all emergency stop circuits 1, causing all emergency stop modules 2 to be de-energized. This causes the switch module 3 to disconnect the main power supply circuit 4, thus achieving emergency stop control. Meanwhile, this application is equipped with at least two emergency stop circuits 1. When only part of the emergency stop circuit 1 is disconnected due to non-human factors, only part of the emergency stop module 2 will be in a de-energized state, while the other part of the emergency stop module 2 will still be in a energized state. As long as any emergency stop module 2 is in a energized state, the switch module 3 will be in a conducting state, that is, the main power supply circuit 4 will not be disconnected. This ensures that the main power supply circuit 4 will only be disconnected when the emergency stop switch 5 is manually triggered by the staff, causing all emergency stop modules 2 to be in a de-energized state. This effectively avoids the situation where the emergency stop control is mistakenly triggered due to the failure of a single emergency stop circuit 1, and can prevent the unexpected shutdown of electrical equipment such as ships, thus ensuring navigation safety.

[0042] Understandably, the emergency stop control system in related technologies only has one emergency stop circuit 1. When emergency stop circuit 1 is broken due to a fault, it will mistakenly trigger the emergency stop mechanism, causing unexpected power outages in ship and other electrical equipment, resulting in unexpected shutdowns and affecting the safety of ship and other electrical equipment. This application, however, sets up at least two emergency stop circuits 1, and each emergency stop circuit 1 is equipped with an emergency stop module 2. Only when all emergency stop modules 2 are de-energized, i.e., all emergency stop circuits 1 are disconnected, will the main power supply circuit 4 be disconnected via the switch module 3. This effectively avoids unexpected shutdowns of ship and other electrical equipment due to partial circuit breakers in emergency stop circuits 1, ensuring that ship and other electrical equipment will not be accidentally triggered and thus ensuring navigational safety.

[0043] For example, vibrations of electrical equipment such as ships can cause loosening of wiring, salt spray corrosion can cause contact oxidation, and mechanical fatigue fracture of cables can all lead to unexpected circuit breakage in emergency stop circuit 1.

[0044] In some examples, the emergency stop module 2 can be directly connected to the switch module 3, or it can be indirectly connected to the switch module 3.

[0045] In some cases, emergency stop circuit 1 is connected to a power source, so when emergency stop circuit 1 is connected, emergency stop module 2 will be in a powered-on state, and when emergency stop circuit 1 is disconnected, emergency stop module 2 will be in a powered-off state.

[0046] In some examples, the number of emergency stop switches 5 may be one or at least two. Emergency stop switches 5 may be located in the cockpit, outside the battery compartment of electrical equipment such as ships, or in any other suitable location of electrical equipment such as ships.

[0047] In some examples, the switching module 3 may be a circuit breaker, a MOSFET, or any other suitable switching element.

[0048] In some embodiments, see Figure 2 and Figure 4 The emergency stop control system also includes an on / off module 6, which is connected to the emergency stop module 2. A switch module 3 is also connected to the on / off module 6. The on / off module 6 is used to change the on / off state of the switch module 3. When any emergency stop module 2 is energized, the emergency stop module 2 causes the on / off module 6 to be in a first state, so that the switch module 3 is in a conducting state. When all emergency stop modules 2 are de-energized, the emergency stop module 2 causes the on / off module 6 to be in a second state, so that the switch module 3 disconnects the main power supply circuit 4.

[0049] It is understandable that connecting the on / off module 6 and the emergency stop module 2 allows the state of the emergency stop module 2 to affect the state of the on / off module 6, which in turn can change the on / off state of the switch module 3. Specifically, when any one of the emergency stop modules 2 is energized, it puts the on / off module 6 in a first state, which in turn causes the switch module 3 to be in a conducting state, allowing the main power supply circuit 4 to supply power normally. When all the emergency stop modules 2 are de-energized, they put the on / off module 6 in a second state, which in turn causes the switch module 3 to be in a disconnected state, thereby disconnecting the main power supply circuit 4 and cutting off the power supply to the ship's electrical equipment, thus achieving emergency stop control.

[0050] In some embodiments, see Figure 2 and Figure 4 The switching module 6 is connected between the switch module 3 and the power module 7. In the first state, the switching module 6 disconnects the switch module 3 and the power module 7 so that the switch module 3 is in the on state. In the second state, the switching module 6 connects the switch module 3 and the power module 7 so that the switch module 3 is in the off state.

[0051] It is understandable that by placing the on / off module 6 between the switch module 3 and the power module 7, the state change of the on / off module 6 can switch the connection between the switch module 3 and the power module 7 between on and off.

[0052] When the emergency stop switch 5 is not triggered, even if part of the emergency stop circuit 1 is disconnected due to a fault, the switching module 6 will be in the first state. At this time, the switching module 6 disconnects the switch module 3 and the power module 7, making the switch module 3 in the conducting state, so that the main power supply circuit 4 can supply power normally. When the emergency stop switch 5 is triggered, all emergency stop circuits 1 are disconnected, and the emergency stop module 2 makes the switching module 6 in the second state. At this time, the switching module 6 connects the switch module 3 and the power module 7, making the switch module 3 in the disconnected state, so that the main power supply circuit 4 is disconnected by the switch module 3 to cut off the power supply to the ship and other electrical equipment, thereby realizing emergency stop control.

[0053] It should be noted that when switch module 3 is connected to power module 7, power module 7 supplies power to switch module 3, causing switch module 3 to switch from the on state to the off state, thereby cutting off the main power supply circuit 4. When switch module 3 is disconnected from power module 7, power module 7 cannot supply power to switch module 3, so switch module 3 will remain in the on state, allowing the main power supply circuit 4 to supply power normally.

[0054] In some embodiments, the switch module 3 can be an intelligent switch module 3. In this case, it is not necessary to connect the on / off module 6 between the switch module 3 and the power supply module 7; simply connecting the on / off module 6 to the switch module 3 is sufficient. When the on / off module 6 is in the first state, it sends a signal to the switch module 3. Upon receiving the signal, the switch module 3 remains in the on state, allowing the main power supply circuit 4 to supply power normally. When the on / off module 6 is in the second state, it does not send a signal to the switch module 3, and the switch module 3 switches to the off state to cut off the main power supply circuit 4, thus achieving emergency stop control. It should be noted that in this example, the focus is on the application of the intelligent switch module 3 and the on / off module 6. The judgment process of the intelligent switch module 3 is not the focus of this application, and existing intelligent switch modules 3 can complete the judgment process of this example.

[0055] In some embodiments, see Figure 2 and Figure 4 At least two emergency stop circuits 1 include a first emergency stop circuit 11 and a second emergency stop circuit 12, and emergency stop module 2 includes a first emergency stop module 21 and a second emergency stop module 22.

[0056] The first emergency stop module 21 includes a first coil K13 and a first auxiliary contact K13.1. The first coil K13 is connected in series with the first emergency stop circuit 11.

[0057] The second emergency stop module 22 includes a second coil K14 and a second auxiliary contact K14.1. The second coil K14 is connected in series with the second emergency stop circuit 12. The first auxiliary contact K13.1 and the second auxiliary contact K14.1 are connected in parallel and then in series between the switching module 6 and the power module 7, so that the switching module 6 can switch between the first state and the second state.

[0058] Understandably, when the first emergency stop circuit 11 is in the conducting state, the first coil K13 is energized; when the second emergency stop circuit 12 is in the conducting state, the second coil K14 is energized; when the first emergency stop circuit 11 is in the open state, the first coil K13 is de-energized; and when the second emergency stop circuit 12 is in the open state, the second coil K14 is de-energized. The energization and de-energization of the first coil K13 affect the closing and opening of the first auxiliary contact K13.1, and the energization and de-energization of the second coil K14 affect the closing and opening of the second auxiliary contact K14.1.

[0059] When the switching module 6 is powered on, it is in a first state; when powered off, it is in a second state. This allows the first auxiliary contact K13.1 to be closed when the first coil K13 is energized and open when the first coil K13 is de-energized. Similarly, the second auxiliary contact K14.1 is closed when the second coil K14 is energized and open when the second coil K14 is de-energized. The first auxiliary contact K13.1 and the second auxiliary contact K14.1 are connected in parallel and then in series between the switching module 6 and the power supply module 7. Only when both the first auxiliary contact K13.1 and the second auxiliary contact K14.1 are open will the connection between the switching module 6 and the power supply module 7 be broken, and the switching module 6 will be in a de-energized state, thereby causing the switch module 3 to disconnect the main power supply circuit 4. In other words, when one of the first emergency stop circuit 11 and the second emergency stop circuit 12 is disconnected due to a fault, the switching module 6 can still maintain connection with the power supply module 7. The switching module 6 remains in the first state, so that the switch module 3 is in the conducting state, and the main power supply circuit 4 can maintain power supply. This effectively avoids the situation where the emergency stop control is accidentally triggered due to a fault in a single emergency stop circuit 1, and can prevent unexpected shutdowns of electrical equipment such as ships, thus ensuring navigation safety.

[0060] In some examples, the first emergency stop module 21 and the second emergency stop module 22 are, for example, relays.

[0061] For details, please refer to Figure 3 and Figure 4The switching module 6 includes a third coil K1 and a third auxiliary contact K1.2. The first auxiliary contact K13.1 and the second auxiliary contact K14.1 are connected in parallel and then in series between the third coil K1 and the power module 7. The third auxiliary contact K1.2 is connected in series between the switch module 3 and the power module 7.

[0062] Understandably, when at least one of the first emergency stop circuit 11 and the second emergency stop circuit 12 is in a conducting state, at least one of the first coil K13 and the second coil K14 is energized. This causes at least one of the first auxiliary contacts K13.1 and K14.1 to be in a closed state. At this time, the third coil K1 is energized, causing the third auxiliary contact K1.2 to be in a disconnected state. This disconnects the connection between the power supply module 7 and the switch module 3, preventing the power supply module 7 from supplying power to the switch module 3. The switch module 3 remains in a conducting state, allowing the main power supply circuit 4 to supply power normally. When both the first emergency stop circuit 11 and the second emergency stop circuit 12 are in a disconnected state, both the first coil K13 and the second coil K14 are de-energized. Both the first auxiliary contacts K13.1 and K14.1 are in a disconnected state. At this time, the third coil K1 is de-energized, causing the third auxiliary contact K1.2 to be in a closed state. This connects the power supply module 7 to the switch module 3, allowing the power supply module 7 to supply power to the switch module 3. This causes the switch module 3 to be in a disconnected state, disconnecting the main power supply circuit 4 and achieving emergency stop control. In other words, the main power supply circuit 4 will only be disconnected when the emergency stop switch 5 is manually triggered by the staff, causing both the first emergency stop circuit 11 and the second emergency stop circuit 12 to be in the open state. This effectively avoids the situation where the emergency stop control is accidentally triggered due to a fault in a single emergency stop circuit 1, and can prevent unexpected shutdowns of electrical equipment such as ships, thus ensuring navigation safety.

[0063] In some examples, the first auxiliary contact K13.1 and the second auxiliary contact K14.1 are normally open auxiliary contacts, and the third auxiliary contact K1.2 is a normally closed auxiliary contact.

[0064] Understandably, when the first coil K13 is energized, the first auxiliary contact K13.1 is closed; when the second coil K14 is energized, the second auxiliary contact K14.1 is closed; when the third coil K1 is energized, the third auxiliary contact K1.2 is open; when the first coil K13 is de-energized, the first auxiliary contact K13.1 is closed; when the second coil K14 is de-energized, the second auxiliary contact K14.1 is closed; and when the third coil K1 is de-energized, the third auxiliary contact K1.2 is closed.

[0065] When one of the first emergency stop circuit 11 and the second emergency stop circuit 12 is broken due to a fault, one of the first coil K13 and the second coil K14 is de-energized while the other is energized. The power supply module 7 and the third coil K1 can still remain connected, that is, the third coil K1 can still be energized, so that the third auxiliary contact K1.2 is in the open state, thereby disconnecting the connection between the switch module 3 and the power supply module 7. The switch module 3 is in the conducting state, and the main power supply circuit 4 can maintain normal power supply. This effectively avoids the situation where the emergency stop control is accidentally triggered due to the failure of a single emergency stop circuit 1, and can prevent the unexpected shutdown of electrical equipment such as ships, thus ensuring navigation safety.

[0066] In some embodiments, see Figure 3 and Figure 4 The on / off module 6 also includes a fourth auxiliary contact K1.1, which is a normally open auxiliary contact. The fourth auxiliary contact K1.1 is connected in series with the BMS power supply circuit, so that the BMS power supply circuit can switch between the on and off states.

[0067] It is understandable that when the third coil K1 is energized, the fourth auxiliary contact K1.1 is in a closed state, and when the third coil K1 is de-energized, the fourth auxiliary contact K1.1 is in an open state.

[0068] When the emergency stop switch 5 is pressed, both the first emergency stop circuit 11 and the second emergency stop circuit 12 are disconnected, causing the first coil K13 and the second coil K14 to lose power. Consequently, the first auxiliary contact K13.1 and the second auxiliary contact K14.1 are both disconnected, de-energizing the third coil K1 and disconnecting the fourth auxiliary contact K1.1. This disconnects the BMS power supply circuit, stopping power supply to the BMS module and achieving emergency stop control. In other words, pressing the emergency stop switch 5 simultaneously disconnects both the main power supply circuit 4 and the BMS power supply circuit, achieving dual emergency stop control and ensuring the reliability of the emergency stop control.

[0069] In some embodiments, in addition to controlling the on / off state of the switch module 3 through the on / off module 6, the on / off state of the switch module 3 can also be directly controlled by the emergency stop module 2.

[0070] For example, the switch module 3 is an intelligent switch module 3, and the emergency stop module 2 carries a signal transmitter. When the emergency stop module 2 is powered on, it sends a signal to the switch module 3. When the switch module 3 receives a signal from at least one emergency stop module 2, the switch module 3 will be in a conducting state, so that the main power supply circuit 4 is in a normal power supply state. When all emergency stop modules 2 are powered off, the switch module 3 cannot receive the signal sent by the emergency stop module 2, and the switch module 3 will be in a disconnected state, so that the main power supply circuit 4 is disconnected, thereby cutting off the power supply to the ship and other electrical equipment, and realizing emergency stop control. In other words, even if part of the emergency stop circuit 1 is disconnected due to non-human factors, only some of the emergency stop modules 2 will be de-energized, while the other part will remain energized. As long as any emergency stop module 2 is energized, the switch module 3 will receive a signal and become conductive, meaning the main power supply circuit 4 will not be disconnected. This ensures that the main power supply circuit 4 will only be disconnected when an operator manually triggers the emergency stop switch 5, causing all emergency stop modules 2 to be de-energized and the switch module 3 can no longer receive signals from the emergency stop modules 2. This effectively avoids the situation where a single emergency stop circuit 1 malfunctions and falsely triggers the emergency stop control, preventing unexpected shutdowns of ship and other electrical equipment and ensuring navigational safety. It should be noted that in this example, the focus is on the application of the intelligent switch module 3 and the emergency stop module 2. The judgment process of the intelligent switch module 3 is not the focus of this application, and existing intelligent switch modules 3 can complete the judgment process of this example.

[0071] In some embodiments, the emergency stop control system further includes a fault alarm element. The emergency stop module 2 is connected between the power supply module 7 and the fault alarm element. When the emergency stop module 2 is in a powered-on state, the emergency stop module 2 disconnects the power supply module 7 and the fault alarm element. When the emergency stop module 2 is in a powered-off state, the emergency stop module 2 connects the power supply module 7 and the fault alarm element.

[0072] Understandably, when one of the emergency stop circuits 1 is disconnected due to a fault, the emergency stop module 2 on that emergency stop circuit 1 will be de-energized. The emergency stop module 2 will connect the power supply module 7 and the fault alarm element, causing the fault alarm element to issue an alarm. This allows staff to promptly inspect the emergency stop circuit 1, enabling real-time online monitoring of the emergency stop circuit 1 and issuing an alarm when the emergency stop circuit 1 is disconnected due to a fault, thus ensuring the stability of the emergency stop circuit 1.

[0073] Understandably, if staff do not press the emergency stop button but still hear a fault alarm, it indicates that emergency stop circuit 1 has malfunctioned.

[0074] In some examples, the number of fault alarm elements is the same as the number of emergency stop modules 2, and there is a one-to-one correspondence between the fault alarm elements and the emergency stop modules 2.

[0075] In some examples, the fault alarm element can be a separate component, such as an audible or luminous element. The fault alarm element can also be a BMS module or integrated into a BMS module. When the power module 7 and the fault alarm element are connected, the BMS module receives the voltage from the power module 7, thus determining that the emergency stop circuit 1 has malfunctioned.

[0076] For details, please refer to Figure 3 and Figure 4 At least two emergency stop circuits 1 include a first emergency stop circuit 11 and a second emergency stop circuit 12, and emergency stop module 2 includes a first emergency stop module 21 and a second emergency stop module 22.

[0077] The first emergency stop module 21 includes a first coil K13 and a fifth auxiliary contact K13.2. The first coil K13 is connected in series with the first emergency stop circuit 11. The second emergency stop module 22 includes a second coil K14 and a sixth auxiliary contact K14.2. The fifth auxiliary contact K13.2 and the sixth auxiliary contact K14.2 are normally closed auxiliary contacts.

[0078] The second coil K14 is connected in series with the second emergency stop circuit 12, the fifth auxiliary contact K13.2 is connected between the power supply module 7 and the fault alarm element, and the sixth auxiliary contact K14.2 is connected between the power supply module 7 and the fault alarm element.

[0079] Understandably, when the first emergency stop circuit 11 is open, the first coil K13 is de-energized, and when the second emergency stop circuit 12 is open, the second coil K14 is de-energized. When the first coil K13 is de-energized, the fifth auxiliary contact K13.2 will close, and when the second coil K14 is de-energized, the sixth auxiliary contact K14.2 will close.

[0080] When the first emergency stop circuit 11 or the second emergency stop circuit 12 is broken due to a fault, the first coil K13 or the second coil K14 will be de-energized, causing the fifth auxiliary contact K13.2 or the sixth auxiliary contact K14.2 to close, thereby connecting the power supply module 7 and the fault alarm element. The fault alarm element will issue a fault alarm, allowing staff to repair the faulty circuit in a timely manner.

[0081] In this application, the power module 7 is, for example, a 24V power supply or a 48V power supply. The accompanying drawings of this application illustrate a 24V power supply as an example.

[0082] According to the embodiments of the second aspect of this application, see Figure 2 The electrical equipment includes the aforementioned emergency stop control system.

[0083] According to the embodiments of this application, during normal operation, the emergency stop switch 5 is not triggered, and at least two emergency stop circuits 1 are in a conducting state. Therefore, the emergency stop modules 2 at each emergency stop circuit 1 are energized, and the switch module 3 is in a conducting state, allowing the main power supply circuit 4 to supply power normally. In an emergency, when an operator triggers the emergency stop switch 5, all emergency stop circuits 1 are disconnected, all emergency stop modules 2 are de-energized, and the switch module 3 disconnects the main power supply circuit 4, thus achieving emergency stop control. Meanwhile, this application is equipped with at least two emergency stop circuits 1. When only part of the emergency stop circuit 1 is disconnected due to non-human factors, only part of the emergency stop module 2 will be in a de-energized state, while the other part of the emergency stop module 2 will still be in a energized state. As long as any emergency stop module 2 is in a energized state, the switch module 3 will be in a conducting state, that is, the main power supply circuit 4 will not be disconnected. This ensures that the main power supply circuit 4 will only be disconnected when the emergency stop switch 5 is manually triggered by the staff, causing all emergency stop modules 2 to be in a de-energized state. This effectively avoids the situation where the emergency stop control is mistakenly triggered due to the failure of a single emergency stop circuit 1, and can prevent the electrical equipment from unexpectedly shutting down, thus ensuring navigation safety.
