Description

Technical Field

[0001] The present invention relates to the field of CT scanning technology and related technical fields, and in particular to a power supply control method, device, equipment and medium applicable to a CT scanning system. Background Art

[0002] CT (Computed Tomography) is a medical imaging technology. It uses X-ray beams to scan the human body and uses computer processing to produce detailed images of the body's internal structures. CT scanning is widely used in the diagnosis of various diseases due to its fast and clear imaging capabilities.

[0003] CT provides a scientific and intuitive basis for the diagnosis of diseases, and has become one of the indispensable medical devices for clinical doctors to diagnose and treat diseases. In the process of clinical diagnosis, CT is widely used in physical examination, screening, diagnosis and differentiation, efficacy evaluation and prognosis. For hospitals, in addition to the high cost of CT equipment itself, its high power consumption and high peak power will also bring many new problems to the hospital. For example, an ordinary 64-row 128-layer CT can reach a peak power of 100KW. To install such a CT, the power supply capacity of the installation site must be no less than 100KW, that is, the power supply current needs to be greater than 100A. However, in many grassroots hospitals, such a high power supply capacity cannot be met, or considering the time and cost costs brought by the power expansion and transformation, the hospital has no intention to expand the power capacity.

[0004] Therefore, how to solve the time cost and budget cost brought about by the hospital's power expansion and transformation has become an urgent problem to be solved. Summary of the invention

[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0027] Based on the problems existing in the prior art, the present disclosure provides a CT scanning system power supply control method, which is applied to a CT scanning power supply device. Figure 1 is a flow chart of a power supply control method for a CT scanning system provided by an embodiment of the present disclosure, Figure 2 is a schematic diagram of a CT scanning power supply device provided by an embodiment of the present disclosure, combined with Figure 1 and Figure 2 , the CT scanning system power supply control method includes: S110 , when receiving a power-on control instruction of the CT scanning system, outputting a first control signal to the first switch module to control the first switch module to be attracted, and then supplying power to the load power supply of the CT scanning system through the grid power input signal.

[0028] In the CT scanning system power supply control method provided in the embodiment of the present application, in order to realize the power supply to the CT scanning system, the power supply to the CT scanning system is realized by controlling the conduction state of the switch module in the CT scanning power supply device and the charging state of the power supply module.

[0029] Specifically, Figure 2As shown, the CT scanning power supply device includes a first switch module, a second switch module, a third switch module, a charging module, a power module and an inverter module. The first ends of the first switch module and the second switch module respectively receive grid power input signals, the second end of the first switch module is electrically connected to the load power supply of the CT scanning system, the second end of the second switch module is electrically connected to the first end of the charging module, the second end of the charging module is electrically connected to the first end of the power module, the second end of the power module is electrically connected to the first end of the third switch module, the second end of the third switch module is electrically connected to the first end of the inverter module, and the second end of the inverter module is electrically connected to the high-voltage generator power supply of the CT scanning system.

[0030] In the prior art, when the CT scanning system needs to perform an exposure scan, the peak power of the CT scanning system is relatively large. Combined with the power of the CT scanning system, it satisfies: P=UI, U is the power supply voltage, and I is the power supply current. When the power supply voltage of the CT scanning system is a fixed value, in order to increase the peak power of the CT scanning system, the power supply current of the CT scanning system can be increased. When the power supply current required by the CT scanning system increases, the hospital needs to expand its power capacity, that is, it needs to increase the input current input to the CT scanning system through the grid power input signal. However, the cost of power expansion for the hospital is relatively high. Based on the problems existing in the prior art, the embodiment of the present disclosure designs a CT scanning power supply device, and the CT scanning power supply device includes a first switch module, a second switch module, a third switch module, a charging module, a power module, and an inverter module. Since the power supply required by other loads of the CT scanning system (such as the rotating motor, the control terminal and the patient support adjustment module) is the normal power supply, the first switch module is connected between the input signal end of the power grid and the load power supply (that is, the rotating motor power supply, the control terminal power supply, and the patient support adjustment module power supply), when the CT scanning system is in the power-on state, the first switch module is controlled to be attracted, so that the first current output by the input signal end of the power grid supplies power to the load power supply, and then the first current is output to the load through the load power supply. Since the power supply required by the light source and the detector module of the CT scanning system is larger than the power supply required by other loads, that is, the peak power supply, the third switch module is connected between the power module and the inverter module, when the CT scanning system is in the exposure state, the third switch module is controlled to be attracted, so that the first current output by the power module is inverted by the inverter module and then outputs the second current to the high-voltage generator power supply, and then the second current is output to the light source and the detector module through the high-voltage generator power supply, so that the working power output by the CT scanning power supply device meets the power requirement of the CT scanning system in the exposure stage of the CT scanning system without the need to expand the power capacity of the hospital.

[0031] In addition, by setting the CT scanning power supply device to also include a second switch module, when the CT scanning system is in a power-off state, the second switch module is controlled to be attracted, so that the first current output by the input signal terminal of the grid power supply supplies power to the power module through the charging module, ensuring that when the CT scanning system performs the next exposure, the first current output by the power module is inverted by the inverter module and then outputs the second current to supply power to the high-voltage generator power supply.

[0032] In a specific embodiment, in combination with Figure 1 and Figure 2 When a power-on control instruction of the CT scanning system is received, the first control signal is first output to the first switch module, and the first switch module is controlled to be attracted by the first control signal. When the first switch module is attracted, the grid power input signal supplies power to the load power supply of the CT scanning system through the first switch module, thereby realizing the power-on of the CT scanning system.

[0033] Specifically, the load power supply of the CT scanning system includes the rotating motor power supply, the control terminal power supply and the patient support adjustment module power supply, that is, all power supplies except the power supplies corresponding to the light source and detector module that need to be turned on during the exposure phase of the CT scanning system are load power supplies.

[0034] It should be noted that when executing step S110, it also includes: when receiving a power-on control instruction of the CT scanning system, outputting a second control signal to the second switch module to control the second switch module to be disconnected.

[0035] Specifically, when a power-on control instruction of the CT scanning system is received, on the one hand, a first control signal is output to the first switch module to control the first switch module to be attracted, so as to supply power to the load power supply of the CT scanning system through the grid power input signal. On the other hand, when the power-on control instruction of the CT scanning system is received, it indicates that the CT scanning system is already in a working state, that is, the CT scanning system may perform an exposure scan at any time. At this time, it is necessary to cut off the path between the power module and the grid power input signal terminal to avoid problems such as aging and short service life of the power module caused by the grid power input signal working for the power module during the working stage of the CT scanning system, so that the power module is charged and discharged at the same time.

[0036] S120 . Upon receiving an exposure control instruction of the CT scanning system, obtain status information of a power module.

[0037] To ensure that the power module can normally supply power to the high-voltage generator power supply of the CT scanning system, when receiving the exposure control instruction of the CT scanning system, the status information of the power module is first obtained, wherein the status information of the power module includes a normal state and an abnormal state. When the power module is in a normal state, the power module can normally supply power to the high-voltage generator power supply of the CT scanning system. When the power module is in an abnormal state, it is first determined whether the power module is in a first abnormal state or a second abnormal state, and then corresponding control operations are performed according to the abnormal state of the power module.

[0038] In a specific implementation, when an exposure control instruction of a CT scanning system is received, status information of a power module is obtained, including: when an exposure control instruction of a CT scanning system is received, voltage information, temperature information and current information of the power module are obtained; resistance information of the power module is determined according to the voltage information and current information; status information of the power module is determined according to the resistance information and temperature information of the power module.

[0039] The resistance information of the power module is determined by acquiring the voltage signal and current information of the power module, and then the state information of the power module is determined according to the resistance information and temperature information of the power module.

[0040] Exemplarily, the greater the resistance value corresponding to the resistance information of the power module, the greater the possibility that the power module is in an abnormal state; the greater the temperature value corresponding to the temperature information of the power module, the greater the possibility that the power module is in an abnormal state.

[0041] S130. When the status information of the power module is in a normal state, output a first control signal to the third switch module to control the third switch module to be attracted, and then supply power to the high-voltage generator power supply of the CT scanning system through the power module and the inverter module.

[0042] When the status information of the power module is in a normal state, the first control signal is output to the third switch module. At this time, after receiving the first control signal, the third switch module is energized, the power module is directly electrically connected to the inverter module, and the power module supplies power to the high-voltage generator through the inverter module. Due to the existence of the inverter module, the first current output by the power module can be inverted into a larger second current after the inverter module, which meets the large current required by the CT scanning system in the exposure stage.

[0043] In the above embodiment, since the current supplied to the load power supply of the CT scanning system through the grid power input signal is the first current, and the current supplied to the high-voltage generator power supply of the CT scanning system through the power module and the inverter module is the second current, and the first current is less than the second current, it can be achieved that when the CT scanning system is powered on, the load power supply is charged by the first current, and the current signal provided by the load power supply to each load in the CT scanning system is the first current, so that each load in the CT scanning system is powered on normally; when the CT scanning system is in the exposure state, the power module inverts the first current into the second current through the inverter module, and supplies power to the high-voltage generator power supply through the second current, and the current signal provided by the high-voltage generator power supply to the light source and the detector module in the CT scanning system is the second current, thereby increasing the current signal output to the light source and the detector module in the CT scanning system, thereby making the working power output by the CT scanning power supply device meet the power requirement of the CT scanning system during the exposure phase of the CT scanning system.

[0044] On the basis of the above embodiment, when the status information of the power module is a first type of abnormal state, a first prompt message is output to prompt the equipment maintenance personnel to replace the power module through the first prompt message; when the status information of the power module is a second type of abnormal state, a second prompt message is output to prompt the equipment maintenance personnel to replace the power module after the exposure of the CT scanning system is completed through the second prompt message.

[0045] Among them, the first type of abnormal state is, for example, undervoltage of the power module, and the operating voltage of the power module is less than the threshold voltage of the inverter module, that is, the current signal cannot be output to the high-voltage generator power supply through the power module and the inverter module. The second type of abnormal state is, for example, the operating voltage of the power module is greater than the threshold voltage of the inverter module and less than the preset threshold voltage, that is, the second current signal can be output to the high-voltage generator power supply through the power module and the inverter module, but the operating voltage of the power module is almost less than the threshold voltage of the inverter module.

[0046] Therefore, when the status information of the power module is a first type of abnormal state, a first prompt message is output to prompt the equipment maintenance personnel to replace the power module through the first prompt message to ensure the normal operation of the CT scanning system; when the status information of the power module is a second type of abnormal state, a second prompt message is output to prompt the equipment maintenance personnel to replace the power module after the CT scanning system receives exposure through the second prompt message to ensure that the CT scanning system replaces the power module after completing the current exposure scan.

[0047] The power supply control method for a CT scanning system provided by an embodiment of the present disclosure first outputs a first control signal to a first switch module to control the first switch module to be attracted when a power-on control instruction of the CT scanning system is received, and then supplies power to a load power supply of the CT scanning system through a power grid input signal; then, when an exposure control instruction of the CT scanning system is received, obtains status information of the power module; finally, when the status information of the power module is in a normal state, outputs a first control signal to a third switch module to control the third switch module to be attracted, and then supplies power to a high-voltage generator power supply of the CT scanning system through a power module and an inverter module; wherein the current supplied to the load power supply of the CT scanning system through the power grid input signal is a first current, and the current supplied to the high-voltage generator power supply of the CT scanning system through the power module and the inverter module is a second current, and the first current is less than the second current. Since the current supplied to the load power supply of the CT scanning system through the grid power input signal is the first current, and the current supplied to the high-voltage generator power supply of the CT scanning system through the power module and the inverter module is the second current, and the first current is less than the second current, it can be achieved that when the CT scanning system is powered on, the load power supply is charged by the first current, and the current signal provided by the load power supply to each load in the CT scanning system is the first current, so that each load in the CT scanning system is powered on normally; when the CT scanning system is in the exposure state, the power module inverts the first current into the second current through the inverter module, and supplies power to the high-voltage generator power supply through the second current, and the current signal provided by the high-voltage generator power supply to the light source and the detector module in the CT scanning system is the second current, thereby increasing the current signal output to the light source and the detector module in the CT scanning system, thereby making the working power output by the CT scanning power supply device meet the power requirement of the CT scanning system during the exposure phase of the CT scanning system.

[0048] Based on the above embodiments, Figure 3 is a flow chart of another CT scanning system power supply control method provided by the embodiment of the present disclosure, such as in combination with Figure 2 and Figure 3 , the CT scanning system power supply control method also includes: S140 . When receiving a power-off control instruction of the CT scanning system, output a second control signal to the first switch module and the third switch module to control the first switch module and the third switch module to be disconnected.

[0049] In a specific implementation, when a power-off control instruction of the CT scanning system is received, a second control signal is output to the first switch module and the third switch module to control the first switch module and the third switch module to be disconnected. At this time, it is necessary to determine the control signal output to the second switch module according to the charge state of the power module and the time-sharing electricity price mechanism, so as to reduce the hospital's electricity expenses on the basis of realizing charging of the power module.

[0050] S150: Determine a charging time of the power module according to the charge state of the power module and the rated capacity of the power module.

[0051] Specifically, the state of charge is the ratio of the remaining capacity of the power module after it has been used for a period of time or has been unused for a long time to its capacity in a fully charged state. It is usually expressed as a percentage, and its value range is 0~1. When SOC=0, it means that the power supply is fully discharged, and when SOC=1, it means that the power supply is fully charged.

[0052] For example, if the state of charge SOC of the power module is 0.8, the rated capacity Q of the power module is 1200 mA, and if the charging current I of the grid power input signal is 600 mA, it can be determined that the charging time of the power module satisfies: t=(Q SOC / I) 1.2=1.92 S160: Determine a control signal to be output to the second switch module according to the charging duration and the time-of-use electricity price mechanism.

[0053] In a specific implementation, a control signal output to the second switch module is determined according to the charging duration and the time-sharing electricity price mechanism, including: determining the charging start time of the power module and the time-sharing interval corresponding to the charging start time according to the time-sharing electricity price mechanism; determining the charging end time of the power module according to the charging duration, the charging start time, and the time-sharing interval corresponding to the charging start time; outputting a first control signal at the charging start time of the power module to control the second switch module to be attracted, and outputting a second control signal at the charging end time of the charging module to control the second switch module to be turned off.

[0054] Among them, determining the charging end time of the power module according to the charging duration, the charging start time and the time-sharing interval corresponding to the charging start time includes: determining the preset charging end time of the power module according to the charging duration and the charging start time; when the preset charging end time of the power module is within the time-sharing interval corresponding to the charging start time, the preset charging end time is the charging end time of the power module; when the preset charging end time of the power module is outside the time-sharing interval corresponding to the charging start time, the end time of the time-sharing interval corresponding to the charging start time is the charging end time of the power module.

[0055] Specifically, by using the time-sharing electricity price mechanism and determining the time-sharing interval for charging the power module, the hospital's electricity expenditure can be further reduced.

[0056] In an exemplary embodiment, if the time-of-use electricity price mechanism includes peak hours, normal hours, and off-peak hours, the specific time periods are divided as follows: peak hours: 10:00-13:00, 17:00-22:00; normal hours: 7:00-10:00, 13:00-17:00, 22:00-23:00; off-peak hours: 23:00-7:00 the next day. After receiving the power-off control instruction of the CT scanning system, the second control signal is first output to the first switch module and the third switch module to control the first switch module and the third switch module to disconnect, and then the charging time of the power module is determined according to the charge state and capacity of the power module, and finally the charging start time of the charging module is determined, that is, the time corresponding to the second switch module being pulled in and the time corresponding to the second switch module being turned off. If the CT scanning system power-off control command is received at 16:00 in the afternoon, and the power module needs to be charged for t, then the charging start time of the charging module is determined to be 23:00, and the charging end time is 23:00+t.

[0057] The above exemplary embodiment represents a time-of-use electricity price mechanism. In other possible implementations, the value of the time-of-use electricity price is related to the weather, weekends within the week, and seasons. The embodiments of the present disclosure do not specifically limit this.

[0058] In addition, during the charging process of the power module, there may be a low period during which the power module cannot be fully charged. At this time, the charging of the power module will be terminated and the power module will be charged again during the next low period.

[0059] Based on the above embodiments, the present disclosure also provides a CT scanning system power supply control device. Figure 4 is a schematic diagram of a power supply control device for a CT scanning system provided by an embodiment of the present disclosure, combined with Figure 2 and Figure 4 , a power supply control device for a CT scanning system, comprising: The first control module 410 is used to output a first control signal to the first switch module when receiving a power-on control instruction of the CT scanning system, so as to control the first switch module to be attracted, and then supply power to the load power supply of the CT scanning system through the grid power input signal; The status information acquisition module 420 is used to acquire the status information of the power module when receiving the exposure control instruction of the CT scanning system; The second control module 430 is used to output a first control signal to the third switch module when the status information of the power module is in a normal state, so as to control the third switch module to be attracted, and then supply power to the high-voltage generator power supply of the CT scanning system through the power module and the inverter module; Among them, the current supplied to the load power supply of the CT scanning system through the grid power input signal is a first current, and the current supplied to the high-voltage generator power supply of the CT scanning system through the power module and the inverter module is a second current, and the first current is smaller than the second current.

[0063] In a specific implementation, the step of determining the control signal output to the second switch module according to the charging duration and the time-of-use electricity price mechanism includes: According to the time-sharing electricity price mechanism, determining the charging start time of the power module and the time-sharing interval corresponding to the charging start time; Determining a charging end time of the power module according to the charging duration, the charging start time and the time-sharing interval corresponding to the charging start time; At the start time of charging of the power module, a first control signal is output to control the second switch module to be pulled in, and at the end time of charging of the charging module, a second control signal is output to control the second switch module to be turned off.

[0064] In a specific implementation, determining the charging end time of the power module according to the charging duration, the charging start time and the time-sharing interval corresponding to the charging start time includes: Determining a preset charging end time of the power module according to the charging duration and the charging start time; When the preset charging end time of the power module is within the time-sharing interval corresponding to the charging start time, the preset charging end time is the charging end time of the power module; When the preset charging end time of the power module is outside the time-sharing interval corresponding to the charging start time, the end time of the time-sharing interval corresponding to the charging start time is the charging end time of the power module.
