At the same time, the term "and / or" used in this specification includes any and all combinations of the related listed items.

[0061] The backup battery in an ultrasonic imaging system is generally integrated with the adapter of the ultrasonic imaging system. The adapter is used to convert the alternating current of the external power supply into direct current to supply power to each device in the ultrasonic imaging system. When the alternating current provided by the external power supply suddenly cuts off, the power management system of the ultrasonic imaging system seamlessly switches to the backup battery for power supply to ensure that the ultrasonic imaging system makes a backup of the data.

[0062] However, if all components of the ultrasonic imaging system are powered during backup battery power supply, it will cause the emergency power supply time of the backup battery to become shorter or even the battery to perform safety protection due to output power limitation, and it cannot reliably ensure that the ultrasonic imaging device performs data backup.

[0063] The power consumption composition of the ultrasonic imaging system generally includes 45% for the ultrasonic acquisition front-end components, 45% for the ultrasonic back-end components, and 10% for the display and other devices. Therefore, when a sudden power outage occurs, the ultrasonic imaging system is emergently powered. At this time, in order to miniaturize the backup battery and have a longer power supply time while ensuring normal functions. So, in the traditional technology, through power management of the ultrasonic imaging system, unnecessary power consumption is reduced. During emergency power supply, derating processing is performed to turn off the ultrasonic acquisition front-end components and other components except those necessary for maintaining the system operation. However, directly turning off the ultrasonic acquisition front-end components as the PCIe device end will cause abnormalities in the ultrasonic back-end components as the PCIe host end or even system blue screen crashes. At the same time, when switching from the emergency power supply state to the normal power supply state, the back-end components as the PCIe host end may not be able to recognize the ultrasonic acquisition front-end components as the PCIe device end.

[0064] For the above reasons, in one embodiment, as Figure 1 shown, a first aspect is provided, which provides a power supply control system, including: a backup battery and a power management system.

[0065] The backup battery is used to provide backup power. When the main power supply is working properly, the backup battery can stop voltage output. The backup battery can be a small-sized battery such as a lithium battery. The main power supply can be a power adapter. The input end of the main power supply can be used to connect to an external power supply, which is used to convert external alternating current into direct current to supply power to each power-consuming part in the medical device.

[0066] The first input end of the power management system is used to connect to the output end of the main power supply. The second input end of the power management system is connected to the output end of the backup battery. The output end of the power management system is connected to the rear-end components of the medical device. Among them, the output end of the main power supply is also connected to the front-end components of the medical device. The front-end components and the rear-end components communicate through a PCIe link. The power management system (Power Management System, PMS) can manage the power supply situation of each power supply device for other devices. It usually has characteristics such as rich peripheral interfaces, small volume, and low power consumption. The power management system can include a PMIC (power management IC, power management chip) and some switching circuits. The PMIC can obtain the power supply status of the main power supply and the backup battery through an interface. The power supply status refers to whether it supplies power to other devices and the magnitude of the supply voltage. According to the obtained power supply status, the PMIC can control the conduction and disconnection states between the ports of the switching circuit whose input end is connected to the output end of the main power supply and the output end of the backup battery, and whose output end is connected to the power-consuming components in the medical device, so as to realize the switching of the power supply sources of each power-consuming component in the medical device. The front-end components refer to the components in the medical device that have data acquisition functions, which are used to obtain sampling data and transmit it to the rear-end components through a PCIe link for processing. For example, the ultrasonic acquisition front-end components in an ultrasonic imaging system. The rear-end components refer to the components that at least have data processing functions. When the main power supply has an abnormal power outage, because the rear-end components undertake data processing and storage functions, the power supply of the rear-end components should be ensured preferentially. The rear-end components can include a memory for data storage.

[0067] In the case where the main power supply has an abnormal power supply and the backup battery is not supplying power, the above-mentioned power management system controls the backup battery to supply power to the rear-end components on the PCIe link and reduces the power supply to the front-end components.

[0068] The implementation of controlling the backup battery to supply power to the backend device on the PCIe link can be that a normally open switch is connected in series between the second input terminal of the power management system and the backup battery. When the main power supply is abnormal and the backup battery is not supplying power, the power management system controls the normally open switch to close, and the output voltage of the backup battery flows into the power management system. After passing through the power management system, it is output to the backend component and the front-end component to supply power to the backend component and supply power to the front-end component with a derated voltage. The derated power supply can be understood as supplying power to the front-end component with a voltage smaller than the rated voltage of the front-end component. At this time, the front-end component does not perform data acquisition and only maintains the smoothness of the PCIe link with the backend component. On this basis, the derated power supply criterion can be to significantly derate to better reduce power consumption, thereby extending the power supply duration of the backup battery. Taking an ultrasound imaging system as an example, when the FPGA (Field Programmable Gate Array) core at the PCIe device end is abnormally powered off, it will cause the CPU (Central Processing Unit) of the PC (Personal Computer) in the ultrasound imaging system to be abnormal, resulting in an abnormal disconnection of the PCIe link from the front-end device to the backend device. Therefore, for this ultrasound imaging system, the derated output is based on maintaining the FPGA core voltage.

[0069] Specifically, when the main power supply is abnormal, the power management system controls the backup battery to supply power to the backend component on the PCIe link and supply power to the front-end component with a derated voltage. The PCIe link is maintained to ensure that the backend component can continue to perform normal data backup, storage, etc. operations to prevent data loss. And because it prevents the PCIe link from disconnecting, when the main power supply resumes, there is no need to restart the backend component, and the backend component does not need to re-identify the front-end component, etc., thus realizing the rapid recovery of medical equipment. And when the backup battery supplies power, supplying power to the front-end component with a derated voltage can extend the duration of emergency power supply.

[0070] The medical device can be a medical device such as a US (Ultrasound) system, a CT (Computed Tomography) imaging system, and an MR (Magnetic Resonance Imaging) imaging system, etc. This is not an exhaustive list here. It should be understood that the solution provided by the embodiments of the present application is applicable to all systems with emergency power supply and having a PCIe link.

[0071] For example, for an ultrasound imaging system, through the control strategy provided by the embodiments of the present application, the problems of PCIe host freezing, system abnormality, and PCIe device - end recognition caused by the disconnection of the PCIe link during the switching between the two states of emergency power supply and normal power supply between the ultrasound acquisition front - end component as the PCIe device - end and the back - end component as the PCIe host - end are solved. In addition, when the main power supply is restored, the ultrasound imaging system can be quickly restored.

[0072] In one embodiment, after controlling the backup battery to supply power to the back - end component on the PCIe link and reducing the power supply to the front - end component, the power - off of the main power supply to the medical device can be controlled to avoid power - supply interference to the power - consuming components in the medical device when the output voltage of the main power supply is not zero. Of course, the connection between the output end of the main power supply and the first input end of the power - management system can also be maintained all the time. When the main power supply is restored, the power supply to all the power - consuming components in the medical device can be immediately restored.

[0073] In one embodiment, the front - end component includes a transceiver. The power - management system is used to control the backup battery to supply normal power to the transceiver on the PCIe link when the main power supply is abnormally powered and the backup battery is not powered. Prioritizing the normal power supply of the transceiver can prevent the abnormal disconnection of the PCIe link between the front - end component and the back - end component. After the main power supply is restored, the problem of the back - end component starting earlier than the front - end component and resulting in the inability to recognize the front - end component will not occur, and based on the maintenance of the link, it can be quickly restored.

[0074] To further reduce the load power consumption when the backup battery supplies power, in one embodiment, the power - management system is also used to control the backup battery to supply power to other devices in the front - end component at a reduced rate when the main power supply is abnormally powered and the backup battery is not powered. By only keeping the transceiver in the front - end component normally powered and reducing the power supply to other devices, other devices enter a low - power working state or a sleep state to further extend the usage time of the backup battery.

[0075] In one embodiment, the power management system is further configured to control the main power supply to power all the electrical components in the medical device and disconnect the power supply of the backup battery when the main power supply resumes normal power supply. When the main power supply resumes, the power management system seamlessly switches to the main power supply mode. In this mode, the main power supply powers each electrical component in the medical device, and the backup battery is disconnected from the power supply. Since the PCIe link was not interrupted before, the medical device can be quickly restored. After the front-end component collects data, it can be quickly sent to the back-end component. The back-end component can quickly process the data based on the data stored during the emergency power supply of the backup battery and the newly received data, and output the results expected by the user. For example, when the medical device is an ultrasonic imaging system, based on the above power supply control system, after a power outage, the ultrasonic scanning and sampling can be quickly continued. The back-end component can quickly output the ultrasonic imaging results based on the previously stored data and the newly sampled data. The staff does not need to execute the ultrasonic scanning process from the beginning again. On the one hand, the work efficiency is improved, and on the other hand, the reliability of the ultrasonic imaging system is improved.

[0076] In one embodiment, as Figure 2 shown, the power supply control system further includes: an ATX power supply. The input end of the ATX power supply is connected to the output end of the power management system, and the output end of the ATX power supply is connected to the back-end component and the front-end component. The power management system is further configured to control the backup battery to supply power to the ATX power supply and control the ATX power supply to supply power to the back-end component and supply power to the front-end component at a derated level when the main power supply is abnormal and the backup battery is not supplying power.

[0077] The ATX power supply refers to a power supply that can convert the input voltage into DC 5V, 12V, and 24V used inside the medical device. The power management system can supply power to the back-end component through the ATX power supply. By controlling the backup battery to supply power to the ATX power supply when the main power supply is abnormal and the backup battery is not supplying power, the power management system can perform an inverse boost conversion on the output voltage of the backup battery and then convert it into 220V AC and input it to the input end of the ATX power supply, so that the ATX power supply converts the 220V AC into DC 5V, 12V, and 24V. The connection relationship between the ATX power supply and the back-end component depends on the selection of the back-end component.

[0078] When the medical device is an ultrasonic imaging system, in addition to inputting voltage to the power management system, the main power supply is also used to provide 24V direct current for the front-end components. At this time, by controlling the ATX power supply to normally output 12V voltage, the normal power supply of the transceiver can be ensured, so that the transceiver (for example, any one of the serial high-speed transceivers such as GTP, GTX, GTH, or GTZ integrated in the front-end FPGA) is normally powered, and other loads in the front-end components enter the silent state (a mode that processes itself without disturbing the user) or the low-power mode. The 24V voltage output terminal of the ATX power supply performs derated output. The 24V derated voltage can still keep the transceiver in the front-end components working normally, maintain the PCIe link between the front-end components and the back-end components, and at the same time make other devices in the front-end components enter the silent state or the low-power state, lengthen the power supply duration of the backup battery, and is beneficial to the miniaturization design of the backup battery.

[0079] To facilitate the user to operate the device when the main power supply is abnormally powered off, in one embodiment, the power supply control system further includes: a voltage conversion module, the input end of the voltage conversion module is connected to the output end of the power management system, and the output end of the voltage conversion module is used to connect to the display. The power management system is further configured to control the backup battery to supply power to the voltage conversion module when the main power supply is abnormally powered and the backup battery is not powered, so that the voltage conversion module supplies power to the display. By supplying power to the display, it is convenient for the user to operate according to the display content of the display. For example, operations such as data storage, forwarding, and latching are performed. It may also include operations such as stopping data acquisition of the front-end components.

[0080] In one embodiment, based on the same concept, a power supply control method is provided, which is applied to the power management system. The first input end of the power management system is used to connect to the output end of the main power supply, the second input end of the power management system is connected to the output end of the backup battery, and the output end of the power management system is connected to the back-end components of the medical device; wherein, the output end of the main power supply is also connected to the front-end components of the medical device, and the front-end components communicate with the back-end components through a PCIe link. For the definitions of the power management system, the backup battery, and the connection implementation of each part, reference can be made to the description in the above system embodiment, which will not be elaborated here.

[0081] In one embodiment, as Figure 3 shown, the power supply control method includes:

[0082] S302, obtaining the power supply status of the main power supply and the power supply status of the backup battery.

[0083] The detection ports of the power management system can be respectively connected to the output end of the main power supply and the output end of the backup battery to obtain their power supply status. The power supply status includes whether power is transmitted externally and the magnitude of the output voltage.

[0084] S304. When the main power supply is abnormal and the backup battery is not powered, control the backup battery to supply power to the backend components on the PCIe link and reduce the power supply to the frontend components.

[0085] The abnormal power supply of the main power supply means that the power supply voltage provided by the main power supply is not sufficient to support the normal operation of each electrical device in the medical device. For example, when the main power supply is an adapter, the input end of the main power supply is connected to an external power supply, and the output end is connected to a power management system. The abnormal power supply of the main power supply can refer to the abnormal alternating current provided by the external power supply.

[0086] For the explanation of power supply derating, reference can be made to the description in the above embodiments, and details are not elaborated here. The power supply control method provided by the embodiments of the present application monitors the power supply status of the main power supply and the backup battery. When the main power supply is abnormal and the backup battery is not powered, it controls the backup battery to supply power to the backend components on the PCIe link and reduces the power supply to the frontend components, preventing the abnormal disconnection of the PCIe link during emergency power supply, thus avoiding the problem that the frontend components cannot be recognized when the main power supply resumes power supply, and also preventing the problem of PCIe host freezing. And due to the maintenance of the link, when the main power supply resumes power supply, the medical device can quickly resume normal operation.

[0087] In one embodiment, the frontend component includes a transceiver. When controlling the backup battery to supply power to the backend components on the PCIe link and reducing the power supply to the frontend components, as Figure 4 shown, it includes:

[0088] S402. Control the backup battery to supply normal power to the transceiver on the PCIe link.

[0089] By controlling the backup battery to supply normal power to the serial high-speed transceivers such as GTP, GTX, GTH, and GTZ integrated in the FPGA on the PCIe link when the main power supply is abnormal and the backup battery is not powered, the abnormal situation of the CPU of the PC can be avoided when the PC of the medical device is not shut down, thus preventing the abnormal disconnection of the PCIe link between the frontend components and the backend components.

[0090] In one embodiment, as Figure 4 shown, when controlling the backup battery to supply power to the backend components on the PCIe link and reducing the power supply to the frontend components, it further includes:

[0091] S404. Control the backup battery to supply power to other devices in the frontend components at a reduced rate, making other devices enter a silent state or a low-power state to reduce the power consumption of the backup battery and extend the power supply duration of the backup battery.

[0092] In one embodiment, as Figure 4 shown, the power supply control method further includes:

[0093] S406. When the main power supply resumes normal power supply, control the main power supply to supply power to all electrical components in the medical device and disconnect the power supply of the backup battery. Taking an ultrasonic imaging system as an example, when the main power supply resumes normal power supply and the backup battery supplies power, the power management system starts all voltage outputs of the ultrasonic front-end components to ensure that the ultrasonic imaging system can perform scanning work normally. In this mode, since the PCIe link has been kept connected before, there is no need to restart the ultrasonic back-end components, and the ultrasonic imaging system can be quickly restored to normal. Moreover, there is no need to perform other development processing work on the BIOS (Basic Input Output System), which greatly shortens the system development cycle and reduces the development difficulty.

[0094] In one embodiment, as Figure 5 shown, control the backup battery to supply power to the back-end components on the PCIe link and supply power to the front-end components with a derated voltage, including:

[0095] S502. Control the backup battery to supply power to the ATX power supply, and control the ATX power supply to supply power to the back-end components and supply power to the front-end components with a derated voltage;

[0096] Among them, the input end of the ATX power supply is connected to the output end of the power management system, and the output end of the ATX power supply is connected to the back-end components and the front-end components.

[0097] The implementation process of controlling the ATX power supply to supply power to the back-end components and the front-end components can refer to the description in the above embodiments and will not be elaborated here.

[0098] In one embodiment, as Figure 6 shown, the power supply control method further includes:

[0099] S602. When the main power supply is abnormal and the backup battery is not supplying power, control the backup battery to supply power to the voltage conversion module, so that the voltage conversion module supplies power to the display;

[0100] Among them, the input end of the voltage conversion module is connected to the output end of the power management system, and the output end of the voltage conversion module is used to connect to the display. Based on the emergency power supply to the display, it is convenient for the user to perform the device operations expected by the user based on the display content when the main power supply is abnormally powered off.

[0101] It should be understood that although the steps in the flowchart are sequentially shown in the direction of the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise clearly stated in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, at least a part of the steps in the figure may include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily sequential, but can be executed alternately or in turn with at least a part of the steps or stages in other steps or other steps.

[0102] In one embodiment, as Figure 7 shown, a power supply control device is provided, which is applied to a power management system. The first input end of the power management system is used to connect to the output end of the main power supply, the second input end of the power management system is connected to the output end of the backup battery, and the output end of the power management system is connected to the rear-end components of the medical device; wherein, the output end of the main power supply is also connected to the front-end components of the medical device, and the front-end components and the rear-end components communicate through a PCIe link. The power supply control device includes: a status monitoring module 702 and an emergency power supply execution module 704, wherein:

[0103] The status monitoring module 702 is used to obtain the power supply status of the main power supply and the power supply status of the backup battery; the emergency power supply execution module 704 is used to control the backup battery to supply power to the rear-end components on the PCIe link and reduce the power supply to the front-end components when the main power supply has an abnormal power supply and the backup battery has not supplied power. Keep the PCIe link between the front-end components and the rear-end components. When the main power supply resumes later, there is no need to restart the rear-end components, and the rear-end components do not need to re-identify the front-end components. Moreover, since the power supply to the front-end components is reduced, the duration of the emergency power supply of the backup battery when the main power supply has an abnormal power outage can be extended, thereby further improving the reliability during the use of the medical device.

[0104] In one embodiment, the front-end components include a transceiver, and the emergency power supply execution module 704 includes:

[0105] The transceiver normal power supply unit is used to control the backup battery to supply normal power to the transceiver on the PCIe link.

[0106] In one of the embodiments, the emergency power supply execution module 704 further includes:

[0107] The power supply reduction unit is used to control the backup battery to reduce the power supply to other devices in the front-end components except the transceiver.

[0108] In one of the embodiments, as Figure 7 shown, the power supply control device further includes:

[0109] A power supply restoration control module 706, configured to control the main power supply to supply power to all electrical components in the medical device and disconnect the power supply of the backup battery when the main power supply resumes normal power supply.

[0110] In one embodiment, the emergency power supply execution module 704 includes:

[0111] An ATX power supply control unit, configured to control the backup battery to supply power to the ATX power supply, and control the ATX power supply to supply power to the backend components and supply power to the front-end components with a derated power supply;

[0112] Wherein, the input end of the ATX power supply is connected to the output end of the power management system, and the output end of the ATX power supply is connected to the backend components and the front-end components.

[0113] In one embodiment, as Figure 7 shown, the power supply control device further includes:

[0114] A display power supply module 708, configured to control the backup battery to supply power to the voltage conversion module when the main power supply is abnormal and the backup battery is not supplying power, so that the voltage conversion module supplies power to the display;

[0115] Wherein, the input end of the voltage conversion module is connected to the output end of the power management system, and the output end of the voltage conversion module is used to connect to the display.

[0116] For the specific limitations of the power supply control device, reference can be made to the limitations on the power supply control method in the above text, which will not be elaborated here. Each module in the above power supply control device can be implemented in whole or in part by software, hardware, and their combination. The above modules can be embedded in or independent of the processor in the computer device in the form of hardware, or stored in the memory in the computer device in the form of software, so that the processor can call and execute the operations corresponding to the above modules. It should be noted that the division of modules in the embodiments of the present application is illustrative, only a logical function division, and there may be other division methods in actual implementation.

[0117] To better illustrate the implementation process of the solution provided in the embodiments of the present application, here, a medical device is taken as an example of an ultrasonic imaging system for illustration. However, it should be emphasized that the example here does not limit the actual protection scope of the present application.

[0118] As Figure 8 shown, it is a connection schematic diagram of the power supply control system, the main power supply, and components such as the front-end components and the backend components in the ultrasonic imaging system. The front-end components are front-end acquisition components, and the backend components are backend processing components. Others refer to other electrical components other than the front-end acquisition components, backend processing components, and the display listed here.

[0119] The electrical components in the power supply part interact with each power-consuming component of the ultrasonic imaging system through the IO (Input / Output, input / output port). Specifically, it is shown in the following table:

[0120]

[0121] The power supply modes include No Power (shutdown mode), Standby (standby mode), Powered ON (normal power supply mode), and Emergency Powered (emergency power supply mode).

[0122] The switching between different modes is as Figure 9 shown. When the condition XXX() on the arrow is satisfied, the power supply mode switches from the mode at the tail of the arrow to the mode pointed to by the arrow. Among them, XXX() refers to the state of the signal XXX, XXX(0) indicates that the signal is disconnected or is a continuous low level, and XXX( ↓ ) is a low level for a period of time. It should be understood that the XXX signal here can at least include Figure 9 the AC_Present, BATT_E, and PS_ON signals in

[0123] The AC-DC chip in the main power supply converts the input single-phase alternating current in the range of 85 - 300V into 5V direct current. The 5V direct current provides the power supply voltage for the components that need power in the standby state of the ultrasonic imaging system, that is, provides the standby operating voltage in the standby mode. The AC-DC chip also outputs 24V direct current to the power management system and the front-end acquisition component. When the input alternating current is normal, the AC-DC continuously supplies power to the front-end sampling component and the power management system according to the Figure 8 circuit structure schematic diagram shown. The power management system PMS can include an MCU (Microcontroller Unit, microcontroller unit). The MCU can select an MCU with a 5V operating voltage. At this time, the operating voltage of the MCU can be provided by the 5V voltage output by the AC-DC chip. The MCU can output an EN signal to the AC-DC chip to control the operating state of the AC-DC chip. The PMS also has multiple detection ports, which are respectively used to access the USPWR_OK, PWR_REG_OK (a signal used to characterize whether the power register is working properly, 1 when normal, 0 when abnormal), Main_FPGA_PWR_OK, and AC_Present signals. The access of the BATT_E signal can be achieved through the connection between the PMS and the backup battery, Figure 8It is not shown in the figure. The PMS can be connected to the PC in the ultrasonic imaging system via RS232. The PMS also has a PWR_EN port for accessing the PS_ON signal (power on / off signal). The PS_ON signal can be triggered by the power on button. When powered on, when the power on button is pressed for the odd number of times, the generated PS_ON signal drives the PMS to work. When powered on, when the power on button is pressed for the even number of times, the generated PS_ON signal drives the PMS to stop working. The voltage conversion module can be a DC-DC DC conversion chip.

[0124] Here, an example is given for the mutual switching between the Powered ON mode and the Emergency Powered mode.

[0125] In the Powered ON mode, if the alternating current connected to the main power supply is abnormal (i.e., AC_Present(0)), and BATT_E is 0 (the backup battery is not powered), it will switch to the Emergency Powered mode to control the backup battery for emergency power supply. It is necessary to automatically switch the AC-DC to the Emergency Powered state to ensure that the ultrasonic back-end processing component as the PCIe host end does not shut down and performs normal data emergency backup and storage operations.

[0126] In this mode, maintain the output voltage of the PC's ATX power supply, keep the monitor powered on, and only maintain the core voltage of the FPGA in the PCIe device end inside the US host. The rest of the power-consuming components enter the standby or low-power state. Since the Main FPGA is a PCIe device, when the PC is not shut down, it is necessary to maintain the normal power supply of the core voltage of the Main FPGA. Otherwise, abnormal power-off of the Main FPGA will cause the CPU of the PC to be abnormal. To meet the emergency power supply duration, it is necessary to reduce the power supply of the 24V load in the ultrasonic imaging system to ensure the normal power supply of the core voltage of the transceivers such as GTH in the Main FPGA, and other loads enter the silent state or low-power mode.

[0127] The timing diagram in this mode is as Figure 10 shown.

[0128] The process of switching from the Emergency Powered mode to the Powered ON mode:

[0129] In the Emergency Powered mode, when the external alternating current is restored (i.e., AC_Present(1)), and BATT_E is 1, that is, the backup battery is used for emergency power supply. It is necessary for the PMS to simultaneously start all voltage outputs to the ultrasonic front-end acquisition components to ensure that the ultrasonic imaging system can perform normal scanning work.

[0130] In this mode, since the PCIe link remains connected all the time, there is no need to restart the ultrasonic back-end processing component, and the system can be quickly restored to normal without other development and processing work on the BIOS. This greatly shortens the system development cycle and reduces the development difficulty.

[0131] In the Powered ON mode, if PS_ON ( ↓ ), that is, the power-on and -off signal which is a low level for a continuous period of time, is detected, it enters the Standby mode. In this mode, only the output of the standby 5V voltage is maintained. Conversely, in the Standby mode, if PS_ON ( ↓ ), that is, the power-on and -off signal which is a low level for a continuous period of time, is detected, it enters the Powered ON mode.

[0132] In the Emergency Powered mode, if PS_ON ( ↓ ), that is, the power-on and -off signal which is a low level for a continuous period of time, is detected, it enters the No Power mode. At this time, all power supplies are turned off.

[0133] In the Standby mode, if AC_Present(0) is detected, it enters the No Power mode.

[0134] In the No Power mode, if AC_Present(0)&BATT_E(1) or AC_Present(1) is detected, indicating that there is a power supply source, it enters the Standby mode.
