Detailed Description
In order to make the objects, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Fig. 1 is a flowchart illustrating a method of power management according to an embodiment, and as shown in fig. 1, a method of power management is applied to a medical imaging system, the medical imaging system includes a transformer, a first type device and a second type device, the transformer is used for supplying power to the first type device and the second type device, the method includes the following steps:
step S120: and judging whether the medical image system is in a working state.
Step S140: and when the medical image system is in a non-working state, the power supply of the transformer to the first type device is cut off.
The first type device is a device of which the time for recovering the running state after the power supply is cut off is less than the preset time, and the second type device is a device of which the time for recovering the running state after the power supply is cut off is greater than the preset time.
Specifically, in the use of the medical imaging system, in a non-operating state where no imaging object is scanned or the like, in order to save power consumption, power-off processing may be performed on the devices in the medical imaging system. However, in order not to affect the user experience, when the medical imaging system needs to be put into use, the medical imaging system should be able to recover from the low power consumption state to the normal operation state within a certain time, and the expected recovery time is the preset time of the medical imaging system. Therefore, the device for power failure in the medical imaging system is a first type device which can recover the running state within the preset time after power failure, and for a second type device which can not recover the running state within the preset time, the power supply is maintained, so that the normal running state can be recovered within the preset time when the medical imaging system needs to be put into use. The working state of the medical imaging system can be judged by the states of the main scanning component and the control device, and the medical imaging system can be judged to be in a non-working state under the condition that the main scanning component, such as a transmitting device such as a bulb tube, is in a closed state or the control device, such as a computer, does not receive an instruction signal for a long time. After the medical image system is judged to be in a non-working state, the power supply of the transformer to the first type device can be cut off, the power cut-off can be controlled manually through a switch and other devices, and the power cut-off can also be controlled automatically through a power control device arranged in the medical image system.
Further, the specific length of the preset time may be determined according to actual use requirements of different types or models of medical imaging systems, for example, the medical imaging system may be a Computed Tomography (CT) imaging system, and in the CT imaging system, the CT imaging system may include components such as a transformer, a bulb, a rotating motor, a bed motor, a control host, a reconstruction host, an uninterruptible power supply device, a gantry control device, and a temperature control device, where the transformer is used to supply power to other components. Among these components, the temperature control unit is used to maintain the detector at a suitable scanning temperature, if it is powered off, it takes a long time to recover the temperature in the normal operation state, depending on the specific model and temperature, the time to recover the temperature can reach half an hour or more, while other devices can recover to the normal operation state in a short time after power off, or can directly operate normally when power is turned on again. Therefore, the preset time can be set within the time required by the temperature control device to recover to the proper temperature, the temperature control device is a second type device in the medical imaging system, other components are first type devices in the medical imaging system, when the medical imaging system does not work, the power supply of the temperature control unit is kept to keep the temperature suitable for scanning, meanwhile, the power supply of other devices is cut off, the power consumption of the CT imaging system is in a low state, when the CT imaging system needs to be put into use, the first type device is powered again, the CT imaging system can recover to a normal operation state within the set time, and the use of a user cannot be influenced.
It is understood that the medical imaging system may also be a Magnetic Resonance (MR) imaging system, an X-ray imaging system, an Ultrasound (US) imaging system, a Positron Emission Tomography (PET) imaging system, or a multi-modality medical imaging system such as PET-CT or PET-MR, and the specific duration of the preset time may be determined according to the actual use requirement of the medical imaging system for different medical imaging systems.
According to the power management method, when the medical imaging system is in a non-working state, the component capable of recovering the running state within a short time is powered off, and the component needing to recover the running state within a long time is continuously powered on, so that the power consumption of the medical imaging system is reduced to save electric power, the service life of the component is prolonged, and the component can be recovered to a normal running state within a short time when the medical imaging system needs to work.
In one embodiment, the method further includes:
the duration of the preset time is adjusted to adjust the number of the first type device and/or the second type device in the medical image system.
Specifically, a plurality of preset times with different durations can be set in the medical imaging system, and the division condition of the first type device and/or the second type device in the medical imaging system is changed by adjusting the durations of the preset times, so as to adjust the power consumption of the medical imaging system after power failure and the time required for recovering the normal use state. Setting the duration of the preset time to be shorter, the number of the components in the medical system is more than that of the second type devices, the normal operation state can be recovered more quickly, setting the duration of the preset time to be longer, the number of the components in the medical system is more than that of the first type devices, and the power consumption of the medical image system is lower.
Further, the preset time may be adjusted by selecting a shorter preset time in a time period with a higher use frequency and a longer preset time in a time period with a lower use frequency according to a use scene or a situation of the medical imaging system, for example, according to a use frequency of the medical imaging system, so that the medical imaging system may be more quickly restored to a normal operation state in a high-frequency use period. The usage frequency can be determined according to historical usage data of the medical imaging system, for example, the daytime is set as a high-frequency usage period, and the night is set as a low-frequency usage period. Or under the condition that the power consumption is divided into a peak power consumption time interval and a valley power consumption time interval, the preset time with longer time can be selected in the peak power consumption time interval, and the preset time with shorter time can be selected in the time interval with lower use frequency, so that the number of the second type devices in the peak power consumption time interval can be reduced to reduce the power consumption of the medical image system, and the power consumption cost is reduced.
Fig. 2 is a schematic flow chart of a power management method in another embodiment, and in an embodiment, as shown in fig. 2, the power management method further includes:
step S260: and when the medical imaging system is in a non-working state, reducing the working frequency of the second type device.
Specifically, after the power supply of the first type device is cut off, in order to further reduce the power consumption of the medical imaging system, the operating frequency of the second type device may be reduced, so that the second type device is in a state of low power consumption, but the normal operation state can still be recovered within a preset time. For example, for a temperature control device in a CT imaging system, the frequency of detecting and adjusting the temperature can be reduced, the power consumption of the temperature control device is effectively reduced, and the temperature of the bulb can be kept in a proper range. For other medical image systems or other first type devices, corresponding processing can also be performed, for example, the medical image system comprises the first type devices such as a computer, and the like, so that the working frequency of a processor can be reduced, the processor enters an energy-saving or dormant state, the power consumption is effectively reduced, the processor does not need to be restarted when the processor needs to be put into use, and the normal operation state can be recovered within preset time.
In one embodiment, the method further comprises:
step S240: and when the medical image system is in a non-working state, controlling a relay and/or a contactor connected between the transformer and the first type device to be in an open state.
Specifically, the power failure of the first type device in the medical imaging system can be realized by a relay and/or a contactor arranged between the transformer and the first type device, when the medical imaging system is judged to be in a non-working state, the relay and/or the contactor are controlled to be in an open state, the power supply of the first type device is disconnected, when the medical imaging system needs to be put into use, the relay and/or the contactor are controlled to be in a closed state, the transformer restarts to supply power to the first type device, and the medical imaging system is restored to a normal operation state within a preset time.
Fig. 3 is a schematic structural diagram of a medical imaging system according to an embodiment, as shown in fig. 3, in an embodiment, the medical imaging system 300 includes: a transformer 320 for powering the first type device 340 and the second type device 360; a second type device 360, the transformer 320 being in a connected state to a power supply of the second type device 360; when the medical imaging system 300 is in the non-operating state, the transformer 320 disconnects the power supply to the first type device 340. The first-type device 340 is a device whose time for recovering the operation state after the power supply is cut off is less than the preset time, and the second-type device 360 is a device whose time for recovering the operation state after the power supply is cut off is greater than the preset time.
Specifically, the medical imaging system 300 may be a Computed Tomography (CT) imaging system, a Magnetic Resonance (MR) imaging system, an X-ray imaging system, an Ultrasound (US) imaging system, a Positron Emission Tomography (PET) imaging system, or a multi-modality medical imaging system such as PET-CT or PET-MR, and the medical imaging system 300 may include a transformer 320, a first type device 340, and a second type device 360, the first type device 340 and the second type device 360 are electrically connected to the transformer 320, respectively, and the transformer 320 supplies power to the first type device 340 and the second type device 360. When the medical imaging system needs to be put into use, the medical imaging system should be able to recover from the low power consumption state to the normal operation state within a certain time, the expected recovery time is the preset time of the medical imaging system, the first type device 340 is a device whose operation state recovery time after the power supply of the transformer 320 is cut off is shorter than the preset time, and the second type device 360 is a device whose operation state recovery time after the power supply of the transformer 320 is cut off is longer than the preset time. When the medical imaging system 300 is in a non-operating state, the disconnection of the power supply to the second type device 360 may be controlled by a switch or the like provided between the transformer 320 and the first type device 340, or the medical imaging system 300 may automatically control the power-off of the first type device 340. In addition to powering down the first type device 340, the second type device 360 can be in a low frequency operation state to further reduce the power consumption of the medical imaging system, and still ensure that the normal operation state can be recovered within a preset time after the power failure.
Further, for the medical imaging system 300, the first type device 340 generally returns to normal operation within a short time after power is removed, or components that are directly functional when re-energized, while the second type of device 360 is typically one that requires a relatively long time to return to normal operation when de-energized, such as in CT imaging systems, transformers supply power to various components in the system, wherein the temperature control unit is used for keeping the detector at a temperature suitable for scanning, and if the detector is powered off, the temperature in a normal operation state needs to be recovered for a long time, the duration of the preset time is set to the time at which the temperature control unit is restored to the normal operation state, in this system, the temperature control device is a second type device 360, and the bulb, the rotating motor, the patient bed motor, the control host, the reconstruction host, the uninterruptible power supply device, etc. are the first type devices 340 in the medical imaging system. It is understood that the duration of the preset time may be determined or adjusted according to actual use requirements, and the second type device and the first type device are not limited to the above devices, for example, if the duration of the preset time is set to be shorter, the number of the components in the medical system is divided into more second type devices, and the normal operation state can be recovered faster, and if the duration of the preset time is set to be longer, the number of the components in the medical system is divided into more first type devices, and the power consumption of the medical imaging system is lower.
When the medical imaging system 300 is in a non-operating state, the components capable of recovering the operating state in a short time are powered off, and the components requiring the recovery of the operating state in a long time are continuously powered on, so that the power consumption of the medical imaging system 300 is reduced to save power, the service lives of the components are prolonged, and the components can be recovered to a normal operating state in a short time when the medical imaging system 300 needs to operate.
Fig. 4 is a schematic structural diagram of a medical imaging system in another embodiment, and as shown in fig. 4, in an embodiment, based on the structure of the medical imaging system in the foregoing embodiment, the medical imaging system 400 further includes: a relay and/or contactor 482 connected between the transformer and the first type of device; and a power control unit 480 for controlling the supply of power to the first type device 440 from the transformer by controlling the open/close state of the relay and/or the contactor.
Specifically, in the medical imaging system 400, the transformer 420 supplies power to the first type device 440 and the second type device 460, the relay (contactor) 482 is disposed between the transformer 420 and the first type device 440, the relay (contactor) 482 is electrically connected to the transformer 420, the first type device 440, and the power control device 480, respectively, when the medical imaging system is in a non-operating state, the power control device 480 controls the relay (contactor) 482 to be in an open state to reduce power consumption of the medical imaging system 400, and when the medical imaging system 400 needs to be put into use, the power control device 480 controls the relay (contactor) 482 to be in a closed state to restore power supply of the transformer 420 to the first type device 440, so that the medical imaging system restores to a normal operating state. It is understood that a relay and/or a contactor may be disposed between the transformer 420 and the second type device 460, so that the power control device 480 may also control the power supply to the second type device 460, for example, in case that it is determined that the medical imaging system is not used for a long time, the power control device 480 may power down all the first type device 440 and the second type device 460 through the relay and/or the contactor, so as to enable the medical imaging system 400 to be in a power-off state.
