Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0032] In the medical field, different types of patient treatments require different types of treatment chambers, and these chambers need a continuous and uninterrupted power supply during treatment. Related technologies typically use microprocessors to control the power supply of the chambers, switching between emergency and normal power. However, this approach relies heavily on the reliability of the microprocessor, and the switching circuitry is complex.
[0033] Therefore, this application proposes a cabin emergency system, method, device, and cabin. First, referring to... Figure 1 The schematic diagram of the cabin emergency system shown provides a detailed description of the cabin emergency system proposed in this application.
[0034] The cabin emergency system proposed in this application includes a cabin power supply circuit, which includes a normal power supply module and an emergency power supply module. The first switch is the main switch of the cabin power supply circuit. The normal power supply module includes a first power source. The emergency power supply module includes a second power source and a second switch. The first switch and the second switch are linked switches; The cabin power supply circuit uses a first relay to switch between the normal power supply module and the emergency power supply module.
[0035] In some possible implementations, the first power source in this application can be mains power or any other type of power source; this application does not limit the first power source. The normal power supply module provides power to the cabin when the first power source is normal. The emergency power supply module provides power to the cabin when the first power source is abnormal or when other abnormalities exist. The first switch in this application is used to turn the normal power supply module and the emergency power supply module on or off. The first power source supplies power to the normal power supply module; specifically, the first power source can provide power to the normal power supply module and can also provide charging power to the emergency power supply module. The second power source provides power to the emergency power supply module. It is understood that the normal power supply module in this application is used to provide normal power to the cabin, and the emergency power supply module is used to provide emergency power to the cabin. In some embodiments, when the cabin needs power, the first switch is closed to turn on the normal power supply to the normal power supply module; when the cabin does not need power, the third switch is opened to turn off the normal power supply to the normal power supply module. The second switch and the first switch are linked; when the first switch is closed, the second switch is also closed, and the emergency power supply module is in a standby state. When the emergency power supply module needs to work, the normal power supply module and the emergency power supply module are switched via the first relay. It should be noted that the first switch and the second switch in this application can be linked switches, different switches of the same relay, or two switches controlled by a microprocessor to achieve the linkage of the two switches.
[0036] The cabin power supply circuit switches between the normal power supply module and the emergency power supply module via a first relay, thereby enabling the switching between normal power supply and emergency power supply.
[0037] In some embodiments, refer to Figure 2 As shown, switch N01 is the first switch, which is the main power switch for the cabin. When the first power supply is normal, closing the first switch supplies power to the cabin, and opening the first switch disconnects the power supply to the cabin. The first switch is located on the line that supplies power to the normal power supply module and the emergency power supply module. The first switch can be a ship-shaped switch or other types of switches.
[0038] In one embodiment of the present invention, the second switch is in a closed state in both normal power supply mode and emergency power supply mode.
[0039] In one embodiment of the present invention, the second power source is an energy storage power source.
[0040] In one embodiment of the invention, the second power source includes a battery.
[0041] In one embodiment of the present invention, the first relay includes a third switch, the third switch including a moving contact and a first stationary contact; the first power supply is connected to the first stationary contact, and the first power supply supplies power to the cabin through the third switch.
[0042] In one embodiment of the present invention, the second power source is connected to the second stationary contact via the second switch, and the second power source provides emergency power to the cabin via the third switch.
[0043] In one embodiment of the present invention, the cabin power supply circuit realizes the switching of the normal power supply module and the emergency power supply module through a first relay, including: the third switch connects the second stationary contact and the moving contact by an action to realize the emergency power supply mode through the emergency power supply module, or the third switch connects the first stationary contact and the moving contact by an action to realize the normal power supply mode through the normal power supply module.
[0044] The third switch in this application can be a normally open switch. The third switch connects the moving contact and the first stationary contact, allowing the first power source to supply power to the cabin. Alternatively, the third switch can connect the moving contact and the second stationary contact, allowing the second power source to supply power to the cabin. Specifically, when the cabin does not require power or the first power source is abnormal, the first coil of the first relay is not energized, and the third switch connects the moving contact and the second stationary contact, enabling the second power source to supply power to the cabin. When the first coil of the first relay is energized, the third switch connects the moving contact and the first stationary contact, supplying power to the cabin through the first power source. Of course, the third switch can also be a normally closed switch. This application does not limit the form of the third switch. The connection relationship of the third switch can be considered as the third switch being a single-pole double-throw switch.
[0045] In one embodiment of the present invention, the cabin power supply circuit further includes an emergency stop switch, one end of the first switch is connected to the normal power supply module through the emergency stop switch, and the other end of the first switch is connected to the emergency power supply module through the emergency stop switch.
[0046] Figure 2 210 in the diagram refers to the emergency stop switch. In the event of an abnormal power outage, the emergency stop switch cuts off the primary power supply, and the secondary power supply provides emergency power to the cabin. The emergency stop switch is located between the primary switch and the normal power supply module, and between the emergency power supply module and the primary power supply module.
[0047] In one embodiment of the present invention, reference is made to... Figure 2The normal power supply module includes: a switching power supply, a first power supply connected to the input terminal of the switching power supply, a first output terminal 24 of the switching power supply connected to the first stationary contact 22, a moving contact 21 connected to the first power supply terminal 26 of the cabin, a second output terminal 25 of the switching power supply connected to the second power supply terminal 27 of the cabin, and the first output terminal connected to the second output terminal through a first coil; wherein, the first relay J1 includes a first coil.
[0048] A switching power supply can convert the voltage of a primary power source to the required voltage. The primary power source is connected to the input terminal of the switching power supply via a primary switch and an emergency stop switch.
[0049] In one embodiment of the present invention, the emergency power supply module includes a charger, a first power supply is connected to a second power supply through the charger, a third output terminal 28 of the second power supply is connected to a second output terminal, and a fourth output terminal 29 of the second power supply is connected to a second stationary contact 23 through a second switch N02.
[0050] The charger is used to charge the second power source. The first power source is connected to one end of the charger via a first switch and an emergency stop switch, and the other end of the charger is connected to the second power source. The second switch and the first switch are linked switches.
[0051] In one embodiment of the present invention, reference is made to... Figure 3 As shown, the emergency power supply module also includes a time relay J2. The time relay includes a second coil and a fourth switch. The first power supply powers the second coil, and the fourth output terminal is connected to one end of the second switch through the fourth switch.
[0052] In one embodiment of the present invention, the fourth switch is a normally open switch.
[0053] The first power source supplies power to the second coil through the first switch and the emergency stop switch.
[0054] Reference Figure 3 As shown, the two power supply branches / modules involved in this application are as follows: The normal power supply branch / module includes: switch N01 (first switch), emergency stop switch, and relay switch J1 (third switch of the first relay) closed; The emergency power supply branch includes: time relay switch J2, switch N02 (second switch), and relay switch J1 open.
[0055] If relay switch J1 is a normally open contact, the working process is as follows: Under normal operating conditions, after switches N01 and N02 are closed, the first power supply is connected to the cabin to provide lighting. Specifically, relay coil J1 is energized through the switching power supply, relay switch J1 closes, and the moving contact of relay switch J1 connects to the first stationary contact, thus supplying power to the cabin through relay switch J1; the coil of time relay J2 is energized, and time relay switch J2 closes (relay switch J1 is closed, so the emergency lighting branch is not in operation); the emergency stop switch is normally closed; and the normal power supply branch is in operation.
[0056] When the power supply is normally shut off (normal power failure), switches N01 and N02 are open, the coil of relay J1 is de-energized, relay switch J1 is open, the moving contact of relay switch J1 is connected to the second stationary contact, and the normal power supply branch does not work; when switch N02 is open / closed, the emergency lighting branch also does not work, and no lighting is needed at this time.
[0057] In case of an abnormal situation (abnormal power failure), the emergency stop switch opens (if the power grid is abnormal, the lithium battery will automatically supply power according to the connection relationship, and can provide emergency indication). Switches N01 and N02 remain closed, but the relay coil J1 is de-energized, the relay switch J1 opens, and the moving contact of the relay switch J1 connects with the second stationary contact, so the normal power supply branch does not work; the time relay coil J2 is de-energized, and the time relay switch J2 opens with a delay (the delay time is related to the amount of lithium battery charge that can supply lighting time). During the delayed opening of the time relay switch J2, the lithium battery supplies power for cabin lighting.
[0058] When switch N02 is in normal working condition, it is closed when there is lighting; it is open when the power supply is normally turned off; and it is closed during emergency lighting in case of power failure, but it is still in the lighting state.
[0059] In one embodiment of the present invention, reference is made to... Figure 4 As shown, the cabin emergency system also includes a cabin air circuit, which includes a solenoid valve and a manual pressure relief valve; The solenoid valve is located outside the cabin, while the manual pressure relief valve is located inside the cabin.
[0060] In one embodiment of the present invention, the first power supply is connected to the solenoid valve through the first switch and the emergency stop switch. The solenoid valve is used to be in the open state when the cabin experiences an abnormal power failure or a normal power failure, so as to depressurize the cabin.
[0061] In one embodiment of the present invention, the cabin air circuit includes an electric regulating valve, which is located outside the cabin and connected to the power supply terminal of the cabin. The electric regulating valve is used to regulate the air pressure of the cabin.
[0062] In one embodiment of the invention, a manual pressure relief valve is used to assist in depressurizing the cabin.
[0063] In recent years, the application of micro-hyperbaric oxygen chambers has become increasingly widespread. However, manufacturers have rarely addressed the issue of emergency safety system response methods (i.e., coordinated response of electrical and pneumatic systems). For example, in cases where personnel inside the chamber need to quickly exit due to an emergency during operation; when the equipment control system malfunctions and requires an emergency power cut-off to assist personnel exiting; or in the event of a power outage, assistance must be provided to ensure safe exit. Therefore, this application's system response method for micro-hyperbaric oxygen chambers in emergency situations, achieved through the linkage of electrical and pneumatic systems, demonstrates a significant advancement in current product safety performance.
[0064] Specifically, such as Figure 4 The system consists of two parts: 1. Circuit: Includes rocker (2NO) switch, emergency stop switch, 24V lithium battery, relay J1, and 24V switching power supply; 2. Pneumatic circuit: including manual pressure relief valve and solenoid valve.
[0065] Emergency safety system handling methods: 1. The core innovation of the system approach is the emergency lighting during power outages. A rocker switch with two normally open (2NO) interlocking contacts is selected as the main switch of the circuit. One normally open contact, NO1, is connected to a 220V / 50HZ power supply as the main control switch for the micro-pressure oxygen-enriched chamber. When connected, the micro-pressure oxygen-enriched chamber enters the working state; when disconnected, the micro-pressure oxygen-enriched chamber is in a normal power-off state. The other normally open contact, NO2, serves as the logic identification contact for whether the main control switch of the micro-pressure oxygen-enriched chamber is connected to the power supply. When the equipment experiences a normal power outage (i.e., the micro-pressure oxygen-enriched chamber is manually shut off), the emergency lighting circuit is not triggered, and the equipment lighting is normally turned off. When the equipment experiences an abnormal power outage (i.e., the micro-pressure oxygen-enriched chamber experiences an abnormal passive power outage, including a power grid outage or the emergency stop switch being pressed to manually cut off the equipment power), the emergency lighting circuit is triggered, and the equipment lighting immediately switches to backup lithium battery power.
[0066] 2. Linkage Principle: During normal equipment operation, when the emergency stop switch is pressed or the power grid fails, the emergency lighting circuit is triggered, and the cabin lighting switches from system switching power supply to lithium battery power supply to ensure normal cabin lighting. It can be understood that a solenoid valve is a fluid control device that maintains flow when power is off and closes when power is on. Therefore, the solenoid valve in the gas circuit is connected to the first power supply through the first switch and the emergency stop switch. When there is a normal power failure (first switch opens) or an abnormal power failure (emergency stop switch opens), the solenoid valve automatically opens due to power loss, and the cabin manual pressure relief valve can be manually opened to simultaneously release pressure, thereby ensuring the safe and rapid exit of personnel from the cabin. The electric regulating valve in this application is connected to the cabin's power supply and is energized or de-energized simultaneously with the LED lights inside the cabin, used to adjust the voltage inside the cabin as needed.
[0067] In one embodiment of the present invention, the delay time of the time relay is less than or equal to a first threshold; the first threshold is the time for the second power supply to supply power to the cabin.
[0068] In some embodiments, the first threshold may be set as the minimum time for the battery to power the cabin so that the battery has sufficient charge for the cabin to be used during the delay time.
[0069] This application selects a rocker switch with two normally open (2NO) interlocking contacts as the main switch of the circuit. One normally open contact NO1 is connected to a 220V / 50HZ power supply as the main control switch for the hypobaric oxygen chamber. When connected, the hypobaric oxygen chamber enters the working state; when disconnected, the hypobaric oxygen chamber is in a normal power-off state. The other normally open contact NO2 serves as the logic recognition for whether the main control switch of the hypobaric oxygen chamber is connected to the power supply. Contact points. When the equipment experiences a normal power outage (i.e., the power to the hypobaric oxygen chamber is manually switched off), the emergency lighting circuit is not triggered, and the lighting remains off. When the equipment experiences an abnormal power outage (i.e., the hypobaric oxygen chamber experiences an unnatural, passive power outage), the emergency lighting circuit is triggered, and the lighting immediately switches to backup lithium battery power. The emergency lighting time can be manually set within a range of less than 10 minutes using a time relay. During normal operation, the lithium battery does not require startup power, avoiding frequent deep charging and significantly extending its lifespan. Furthermore, the lithium battery is installed externally via a penetrating insertion plug, improving the safety of equipment use.
[0070] On the other hand, refer to Figure 5 This application provides a cabin emergency response method for the aforementioned cabin emergency response system, the method comprising: If the cabin is powered normally, closing the first switch will trigger the closing of the second switch, energizing the first relay so that the third switch can connect the first stationary contact and the moving contact, allowing the normal power supply module to supply power to the cabin. If the cabin experiences an abnormal power outage or a normal power outage, the first relay will lose power, causing the third switch to activate the second stationary contact and the moving contact.
[0071] If the cabin requires power, the first relay is energized, causing the third switch to connect the first stationary contact and the moving contact, thus supplying power to the cabin from the first power source. In another embodiment, if the cabin experiences an abnormal power outage or does not require power, the first relay is de-energized, causing the third switch to connect the second stationary contact and the moving contact. Specifically, if the cabin does not require power, the first relay is de-energized, causing the third switch to connect the second stationary contact and the moving contact, disconnecting the first power source and supplying power to the cabin. If the cabin experiences an abnormal power outage, the first relay is de-energized, causing the third switch to connect the second stationary contact and the moving contact, disconnecting the first power source and supplying power to the cabin. Simultaneously, the second power source is activated via the second switch to supply power to the cabin (this is an abnormal power outage under normal power supply conditions; the first switch is closed, and the second and first switches are linked switches, with the second switch also closed). It is understood that the energization and de-energization of the first relay can be adjusted via a switch or a microprocessor; this application does not impose specific limitations on this.
[0072] In one embodiment of the present invention, the cabin emergency system further includes an emergency stop switch. If the cabin experiences an abnormal power outage or a normal power outage, the first relay is de-energized, causing the third switch to activate the second stationary contact and the moving contact. This includes: If the cabin experiences an abnormal power failure, the emergency stop switch will be disconnected, the first relay will lose power, and the third switch will activate to connect the second stationary contact and the moving contact, allowing the emergency power supply module to supply power to the cabin. If the cabin experiences a normal power outage, the first switch will be disconnected, which will in turn disconnect the second switch, so that neither the normal power supply module nor the emergency power supply module supplies power to the cabin.
[0073] Specifically, under normal power supply conditions, if an abnormal power outage is detected in the cabin, an emergency stop switch can be triggered. Triggering the emergency stop switch de-energizes the first relay, causing the third switch to connect the second stationary and moving contacts, providing emergency power to the cabin from the second power source. In some embodiments, if an abnormal power outage is detected, a signal can be sent via a microprocessor to trigger the emergency stop switch; alternatively, the emergency stop switch can be triggered manually. This application does not limit the triggering method of the emergency stop switch. On the other hand, in the event of a normal power outage, i.e., when the cabin does not require power, the power supply to the cabin is disconnected by opening the first switch.
