Description

Technical Field

[0001] The present invention relates to the field of power electronics technology, and in particular to a mobile X-ray machine power management system and a control method thereof. Background Art

[0002] Modern medical X-ray machines are developing rapidly. Mobile X-ray machines are widely promoted because they do not rely on external power distribution and have flexible mobility. They can be used for bedside diagnosis of patients with limited mobility, outdoor diagnosis, and rural areas without suitable power distribution. The market demand is increasing.

[0003] Among them, the high-voltage generator is an important part of the mobile X-ray machine. The mobile high-voltage generator contains a power supply module with an energy storage function. Users hope that a single charge can be used for a longer time, so it is necessary to scientifically and rationally distribute and manage its internal power in order to reduce power loss and achieve optimal energy saving.

[0004] like Figure 1 As shown, in the prior art, mobile high-voltage generators are mostly managed by switching the power modules of the subsequent stages, namely, the power supply group 102 of the moving parts and the power supply group 103 of the imaging parts, through a switch circuit 101 including a mechanical switch such as a relay. The switch circuit 101 is connected between the power supply module 105 and the power supply group, and the switching is controlled by the control circuit 104. Mechanical switches such as relays are set in the power circuit, are large in size, and have a limited number of actions, which have service life problems, thereby affecting the reliability of the entire product and failing to meet increasingly stringent medical requirements.

[0005] As the functions of mobile X-ray machines increase, high-voltage generators have more working states. The power supply of the power module is realized through relays, etc., and the function is relatively simple. And for cost and reliability considerations, it is generally not desirable to add mechanical switches such as relays to each power module inside the high-voltage generator, so that the power on and off of each power module cannot be flexibly controlled to achieve the best energy-saving effect. In addition, when the mobile X-ray is turned off, the control circuit cannot be cut off, and the loss always exists. The power loss is large during long-term standby.

[0006] In summary, how to reduce the power consumption of X-ray machines and achieve better power management is a technical problem that needs to be solved urgently.

[0007] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0045] In the related art, in the mobile X-ray machine power management system, the power management is performed by switching the rear-stage power module on and off in time by mechanical switches such as relays. This solution has the disadvantages of large power loss.

[0046] The embodiment of the present invention provides a mobile X-ray machine power management system and a control method thereof, so as to reduce the power consumption of the mobile X-ray machine and achieve better power management.

[0047] like Figure 2 As shown, an embodiment of the present invention provides an X-ray machine power management system, which includes: a power supply module 210; a main control module 230, which is connected to a host computer 260, receives an action signal sent by the host computer 260 and obtains status information of the power supply module 210, and outputs a corresponding control signal; a functional component power group, including a moving component power group 240 and an imaging component power group 250, which are respectively connected to the power supply module 210 and the main control module 230, and are used to convert the electric energy of the power supply module 210 according to the control signal and output it to the functional components of the high-voltage generator.

[0048] In the mobile X-ray machine power management system of the embodiment of the present invention, the main control module optimizes power management according to the instructions of the host computer and the status of the power supply module. The main control module can independently control the power on and off of each sub-power module in the functional component power group, and adopts a fully digital power management solution to improve the scientificity, reliability, flexibility and scalability of power management.

[0049] Specifically, the mobile X-ray machine power management system of the embodiment of the present invention removes all switching circuits implemented by mechanical relays, and the operation of the power module is entirely controlled by the control signal of the main control module, thereby improving the reliability and life of the mobile X-ray machine.

[0050] The power supply module 210 may include a battery pack 212 and a battery charger 211. The battery charger 211 is generally connected to the power grid and receives the power grid voltage to charge the battery pack 212. The battery pack 212 may be one or more battery modules. The status information of the power supply module may include battery charging status information, battery non-charging status information, battery power status information, and battery abnormal status information.

[0051] Among them, the battery charging status information refers to the information when the battery is being charged, including the current battery output voltage and charging current; the battery non-charging status information refers to the information when the battery is being discharged, including the current battery output voltage and discharge current; the battery power status information includes the remaining battery power; the battery abnormal status information includes whether the battery is working normally, whether there is overvoltage protection, undervoltage protection, overcurrent protection, overcharge protection, over-discharge protection and over-temperature protection.

[0052] In addition to performing power management according to the action signal received from the host computer, the mobile X-ray machine power management system also makes corresponding adjustments according to the status of the power supply module. Specifically, in the power management scheme of the mobile X-ray machine power management system in the embodiment of the present invention, the working mode of the mobile X-ray machine power management system is adjusted according to the status information such as whether the power supply module is charged and the battery power, so that the power management is more scientific.

[0053] like Figure 2 As shown, the main control module 230 includes: a state signal processing unit 231 and a control signal generating unit 232, wherein the state signal processing unit 231 is electrically connected to the host computer 260, receives the action signal sent by the host computer 260 and sends it to the control signal generating unit 232, and the control signal generating unit 232 generates a control signal according to the action signal and outputs it.

[0054] In some embodiments, the action signal sent by the host computer may include a sleep signal, a full power-on signal, a half power-on signal, and a power-off signal.

[0055] like Figure 2 As shown, the mobile X-ray machine power management system of the embodiment of the present invention further includes: a standby power supply 220, connected to the power supply module 210 and the state signal processing unit 231, for converting the electric energy of the power supply module 210 to power the state signal processing unit 231; and the standby power supply 220 is also electrically connected to the main control module 230 through the first switch 221, and supplies power to the main control module 210 when the first switch 221 is turned on, wherein the first switch 221 is turned on or off under the control of the state signal processing unit 231. The first switch can be a semiconductor switch device, such as IGBT, BJT, MOSFET, but is not limited thereto.

[0056] The embodiment of the present invention introduces a standby power supply for waking up the mobile X-ray machine power management system. When the mobile X-ray machine power management system is in full standby mode, only the standby power supply works, and the standby power supply supplies power to the state signal processing unit, ensuring that the state signal processing unit can receive the action signal of the host computer at any time. When the power-on signal of the host computer is received, the standby power supply will be connected to the main control module through the first switch, and the entire main control module will be fully powered, which greatly reduces the loss of the mobile X-ray machine power management system during long-term standby and increases the utilization rate of battery energy.

[0057] In addition, in the embodiment of the present invention, the operation of each sub-power module except the standby power module is independently controlled by the control signal generating unit 232 of the main control unit 230, and the flexibility and expandability of the system are improved.

[0058] Furthermore, the functional component power supply group includes a moving component power supply group 240 and an imaging component power supply group 250, wherein the moving component power supply group 240 is connected to the power supply module 210 and the main control module 230, and is used to convert the electric energy of the power supply module 210 according to the control signal output by the control signal generating unit 232 and output it to the moving component of the high-voltage generator; the imaging component power supply group 250 is connected to the power supply module 210 and the main control module 230, and is used to convert the electric energy of the power supply module 210 according to the control signal output by the control signal generating unit 232 and output it to the imaging component of the high-voltage generator.

[0059] The moving component power supply group 240 includes several power supply modules for realizing the movement of the mobile X-ray machine and movement-related functions. The imaging component power supply group 250 includes several power supply modules for realizing the imaging and imaging-related functions of the mobile X-ray machine. The host computer 260 refers to the part of the mobile X-ray machine that controls the state of the mobile X-ray machine power management system. It sends a half-start signal (turning on the X-ray machine movement function), a full-start signal (turning on the X-ray machine movement and imaging functions to ensure that the X-ray machine can work normally), a shutdown signal and a sleep signal to the mobile X-ray machine power management system according to actual needs.

[0060] Here, the host computer may be a timing control component of a mobile X-ray machine system, and the specific form may be a mechanical power on / off state switching knob or a user operation software interface, but is not limited thereto.

[0061] In addition, the main control module 230 also includes a detection unit 233, which is connected to the power supply module 210, detects the status information of the power supply module 210 and sends it to the control signal generating unit 232; the control signal generating unit 232 generates a control signal according to the status information of the power supply module 210 and the action signal sent by the host computer 260.

[0062] The detection unit 233 will monitor the status of the power supply module 210 in real time. When the battery pack 212 is low on power and the battery charger 211 is not working, the main control module 230 will give a prompt that the system needs to be charged in time, and prohibit the power module related to the imaging function of the mobile X-ray machine from working, so as to avoid errors in patient diagnosis due to insufficient power of the power supply module 210. When the battery pack 212 is low on power and the battery charger 211 is working, the main control module 230 will allow the power module related to the imaging function of the mobile X-ray machine to work but limit its maximum output power. When the mobile X-ray machine cannot diagnose the patient in time due to insufficient power, the staff will be reminded to charge in time, and the X-ray diagnostic function of the normal dose can be restored by connecting to the mains for charging.

[0063] Figure 3 The following schematically shows the architecture of a mobile X-ray machine power management system according to an embodiment of the present invention. Figure 3 As shown, the motion component power supply group includes at least any one of the following motion power supply modules: a first auxiliary power supply module 301 and a motor drive module 302. The imaging component power supply group includes at least any one of the following imaging power supply modules: an imaging auxiliary power supply 303, a filament power supply 304 connected to the imaging auxiliary power supply 303, and a high-voltage control module 305; a capacitor charger 306, an energy storage capacitor unit 307 connected to the capacitor charger 306, a high-voltage conversion module 308 connected to the energy storage capacitor unit 307, a tube motor drive module 309, and an inverter 310; and a second auxiliary power supply module 311. It should be noted that the motion power supply module and the imaging component power supply module in this case are not limited to this. In some embodiments, the motor drive module 302 mainly drives the X-ray machine to move, for example, so that the X-ray machine can be pushed and moved; in addition, the X-ray machine can also move up and down, for example, the up and down movement of the tube can be provided by the auxiliary power supply in the imaging component power supply group, and this case is not limited to this.

[0064] The power that the first auxiliary power module 301 and the second auxiliary power module 321 can provide may be 12V, 24V or 48V, but is not limited thereto.

[0065] Specifically, Figure 3 As shown, the first auxiliary power module 301 supplies power to the FPGA (Field-Programmable Gate Array) board 312, and the second auxiliary power module 311 supplies power to the integrated machine 313. The motor drive module 302 supplies power to the motor 314. The high-voltage conversion module 308 supplies power to the tube 320, the filament power supply 304 supplies power to the tube filament 321 of the tube 320, and the tube motor drive module 309 supplies power to the tube motor 322 of the tube 320. The inverter 310 supplies power to the imaging flat charger 315. This case is not limited to this.

[0066] The embodiment of the present invention also provides a control method for a power management system of an X-ray machine, the control method comprising: powering on the main control module 230 according to an action signal sent by the host computer 260; and generating a control signal according to the action signal sent by the host computer 260, controlling the functional power module in the functional component power supply group to convert the power of the power supply module and output it to the functional component of the high-voltage generator. Here, the action signal sent by the host computer 260 can be one or more of the following: a sleep signal, a full-on signal, a half-on signal, and a shutdown signal.

[0067] Furthermore, the status information of the power supply module 210 is detected, and a control signal is generated according to the status information of the power supply module 210 and the action signal sent by the host computer 260, so as to control the moving component power supply group 240 to convert the electric energy of the power supply module 210 and output it to the moving component of the high-voltage generator; and control the imaging component power supply group 250 to convert the electric energy of the power supply module and output it to the imaging component of the high-voltage generator.

[0068] Specifically, in the embodiment of the present invention, the working mode of the high voltage generator can also be determined according to the state information of the power supply module 210 and the action signal sent by the host computer 260, and a corresponding control signal can be generated according to the working mode. Among them, the working mode includes at least one of the following: standby mode, moving component power-on mode, imaging component power-on mode, sleep mode, power-feed reminder mode, charging standby mode, charging power-on mode, and reduced power exposure mode.

[0069] Among them, the working mode of the high-voltage generator is different when the battery pack is in a charging state and when it is not in a charging state. And the amount of battery power also affects the working mode of the high-voltage generator. Therefore, corresponding control is required according to different battery states.

[0070] Firstly, when the battery pack is in a non-charging state, the working mode of the high voltage generator is determined according to the action signal.

[0071] In some embodiments, when the main control unit 230 receives a shutdown signal, it can be determined that the working mode of the high voltage generator is the standby mode. In the standby mode, only the standby power supply 220 is put into operation; at this time, the standby power supply only supplies power to a part of the circuit of the main control unit 230, for example, only supplies power to the state signal processing unit 231 in the main control unit 230. Parts other than the state signal processing unit 231 in the main control unit 230 do not work, and the moving component power supply group 240 and the imaging component power supply group 250 do not work.

[0072] In some embodiments, when the main control unit 230 receives a half-power-on signal, it can be determined that the working mode of the high-voltage generator is the moving part power-on mode. In the moving part power-on mode, the standby power supply 220, the main control module 230 and the moving part power supply group 240 can be put into operation. At this time, the state signal processing unit 231 controls the first switch 221 to close and turn on, so that the standby power supply 220 supplies power to the entire main control unit 230 through the first switch 221. And the moving power supply modules in the moving part power supply group 240, for example: the first auxiliary power supply module 301 and the motor drive module 302 start working. The first auxiliary power supply module 301 receives the power from the power supply module 210 to power the FPGA board 312, and the motor drive module 30 receives the power from the power supply module 210 to power the motor 314. This case is not limited to this.

[0073] In some embodiments, when the main control unit 230 receives a full power-on signal and detects that the power level of the battery pack 212 in the power supply module 210 is less than a first threshold, it can be determined that the working mode of the high-voltage generator is a power feeding reminder mode. In this mode, it is generally necessary to prohibit the mobile X-ray machine from working normally to avoid errors in diagnosis due to insufficient power in the power supply module 210. Therefore, in the power feeding reminder mode, generally only the standby power supply 220, the main control module 230 and the moving part power supply group 240 are in operation. For example, in the moving part power supply group 240: the first auxiliary power supply module 301 and the motor drive module 302 are in working state. The moving part power supply group 240 is in operation to facilitate the movement of the X-ray machine, such as pushing the X-ray machine to a place where it can be charged for timely charging. The present case is not limited to this.

[0074] In some embodiments, when the main control unit 230 receives a full power-on signal and detects that the power level of the battery pack 212 in the power supply module 210 is greater than or equal to the first threshold, it can be determined that the working mode of the high-voltage generator is the imaging component power-on mode. In this mode, the battery power is sufficient, and the X-ray machine can work normally and be ready for exposure at any time. Therefore, in the imaging component power-on mode, the standby power supply 220, the main control module 230, the moving component power supply group 240, and the imaging component power supply group 250 are all put into operation under the control of the main control module 230.

[0075] In some embodiments, in standby mode, the status signal processing unit 231 is used to receive a first-stage power-on signal. Only after receiving a first-stage power-on signal, a second-stage power-on signal is received. The second-stage power-on is based on the first-stage power-on. After receiving the second-stage power-on signal, there will be a sleep mode under the second-stage power-on. Among them, the first-stage power-on signal and the second-stage power-on signal are respectively a half-power-on signal and a full-power-on signal. This application does not limit this, it is just one of the application methods.

[0076] Further, in some embodiments, when the main control unit 230 receives a sleep signal and detects that the power level of the battery pack 212 in the power supply module 210 is greater than or equal to the first threshold, it can be determined that the working mode of the high-voltage generator is the sleep mode. Among them, in the sleep mode, the standby power supply 220 and the main control module 230 are in operation, and the moving component power supply group 240 and the partial imaging component power supply group 250 are put into operation under the control of the main control module 230. In the sleep mode, it is generally necessary to ensure that the X-ray machine can move, so the general moving component power supply group 250 works normally. Some imaging component power supplies, such as the second auxiliary power supply module 311, can work normally to supply power to the all-in-one machine 313. The power supply for specific work can be set according to actual needs, and this case does not limit this.

[0077] When the battery pack is in a charging state, the working mode of the high voltage generator is determined according to the action signal.

[0078] In some embodiments, when the main control unit 230 receives a shutdown signal, it can be determined that the working mode of the high-voltage generator is a charging standby mode. In the charging standby mode, the general standby power supply and the main control module are put into operation. Compared with the standby mode when the battery is not in a charging state, this mode can fully turn on the main control module 230. Because the battery pack is charging, the basic power supply requirements of the power supply can be guaranteed, so there is no need to save power and only turn on part of the main control unit 230. Further, at this time, the detection unit 233 of the main control unit 230 will detect the charging state of the power supply module 110.

[0079] In some embodiments, when the main control unit 230 receives a half-startup signal, it can be determined that the working mode of the high-voltage generator is a charging startup mode. In the charging startup mode, the standby power supply 220, the main control module 230, and the power supply group 240 of some moving parts are put into operation. For example, the first auxiliary power supply module 301 in the moving part power supply group 240 can work to power the FPGA board 312. And the general motor drive module 302 does not work, because the battery pack in the power supply module is in a charging state at this time, and it is necessary to ensure that the mobile X-ray machine will not be moved by mistake during the connection to the mains charging process.

[0080] In some embodiments, when the main control unit 230 receives a full power-on signal and detects that the power level of the battery pack 212 in the power supply module 210 is less than a second threshold, it can be determined that the working mode of the high-voltage generator is a derating exposure mode. In the derating exposure mode, the standby power supply 220, the main control module 230, the power pack 240 of some moving parts, and the power pack 250 of the imaging component are put into operation. Similarly, the general motor drive module 302 does not work because the battery pack in the power supply module 210 is in a charging state at this time, and it is necessary to ensure that the mobile X-ray machine will not be moved by mistake during the charging process of connecting to the mains. Furthermore, in this mode, the imaging component power pack 250 basically works normally. When the battery of the mobile X-ray machine is low and the user is eager to use it, conventional X-ray diagnosis can be performed while charging, but the output power will be limited.

[0081] In some embodiments, when the main control unit 230 receives a full power-on signal and detects that the power level of the battery pack 212 in the power supply module 210 is greater than or equal to a second threshold, it can be determined that the working mode of the high-voltage generator is the imaging component power-on mode. This mode is basically the same as the imaging component power-on mode when the battery is not charged. Among them, the standby power supply 220, the main control module 230, the partial moving component power supply group 240, and the imaging component power supply group 250 are all working normally. However, since the battery pack in the power supply module 210 is in a charging state, it is necessary to ensure that the mobile X-ray machine will not be moved by mistake during the process of connecting to the mains for charging, so the motor drive module 302 in the moving component power supply group 240 generally does not work.

[0082] In some embodiments, when the main control unit 230 receives a sleep signal, it is determined that the working mode of the high-voltage generator is a sleep mode. Similarly, the sleep mode is basically the same when the battery is charged and the battery is not charged. Among them, at this time, the standby power supply 220 and the main control module 230 are in operation, and part of the moving component power group 240 and part of the imaging component power group 250 can be put into operation under the control of the main control module 230. For example, the first auxiliary power module 301 in the moving component power group 240 receives the power of the power supply module 210 to power the FPGA board 312, and the second auxiliary power module 311 in the imaging component power group 250 can work normally and power the integrated machine 313. The specific working power module is not limited to this. In some embodiments, since the battery pack in the power supply module 210 is in a charging state, it is also necessary to ensure that the mobile X-ray machine will not be moved by mistake during the connection to the mains charging process, so the motor drive module 302 in the moving component power group 240 is generally not working.

[0083] In some embodiments, the first threshold and the second threshold may be equal; further, in some embodiments, the first threshold and the second threshold may be set to 2%-50% of the power level of the battery pack 212 when it is fully charged.

[0084] like Figure 4 As shown, the mobile X-ray machine power management system will adjust the working mode according to the status information of the power supply module, making the power management more scientific.

[0085] Specifically, Figure 4 As shown, modes 1 to 5 are working modes when the battery pack is in a non-charging state, and modes 6 to 8 are working modes when the battery pack is in a charging state. When the mobile X-ray machine power management system performs power management, the control process and modes are as follows:

[0086] Execute step S410 to determine whether the battery is being charged. If not, execute step S411; if so, execute step S421.

[0087] Step S411, determine that the working mode of the high voltage generator is mode 1, mode 1 is standby mode, the standby power supply 220 works without load, the status signal processing unit 231 in the main control unit 230 works, the other parts of the main control unit 230 do not work, the moving component power supply group 240 and the imaging component power supply group 250 do not work. At this time, the mobile X-ray machine can be said to be in the off state. When the mobile X-ray machine is turned off, only the standby power supply 220 and the status signal processing unit 231 work, and there is only a weak no-load loss, which can greatly reduce the standby loss of the system.

[0088] Furthermore, when the high voltage generator is in mode 1, if the action signal received by the main control unit 230 is a half-startup signal, step S412 is executed.

[0089] Step S412, determine that the working mode of the high voltage generator is mode 2, mode 2 is the moving part power-on mode, in which the control signal generating unit 232 in the main control module 230 will generate a control signal to turn on the moving part power supply group 240, and the motor drive module and other function expansion power supply modules (power supply modules 1-n) can work. At this time, the mobile X-ray machine is in a state where it can be pushed.

[0090] Furthermore, when the high voltage generator is in mode 2, if the action signal received by the main control unit 230 is a full power-on signal, step S413 is executed.

[0091] Step S413, determine whether the battery power is lower than the first threshold. If yes, execute step S414. If no, execute step S415.

[0092] Step S414, determine that the working mode of the high voltage generator is mode 5, which is the power feeding reminder mode, in which only the motor drive module is kept working. At this time, the mobile X-ray machine is low on power and needs to be charged in time. In this mode, keep the power supply related to the mobile X-ray machine motion function in the motion power supply component group 240 turned on. And prompt that the power is low, so that the user can push the mobile X-ray machine to charge.

[0093] Furthermore, in mode 5, if the main control unit 230 receives a shutdown signal, step S410 is executed.

[0094] Step S415, determine that the working mode of the high voltage generator is mode 3-1, mode 3-1 is the imaging component startup mode during the battery non-charging process, in which the control signal generation unit 232 in the main control module 230 will generate a control signal to turn on the imaging component power group 250, and the power supply related to the X-ray image and other function expansion power modules (power modules a~N) work. At this time, the mobile X-ray machine can be pushed and can perform X-ray diagnosis normally. Here, mode 3-1 and mode 3-2 below are both imaging component startup modes. The imaging component startup mode includes the imaging component startup mode during the battery charging process and the imaging component startup mode during the battery non-charging process.

[0095] Furthermore, in mode 3-1, if the main control unit 230 receives a sleep signal, step S416 is executed; if a shutdown signal is received, step S410 is executed.

[0096] Step S416, determine that the working mode of the high voltage generator is mode 4, which is the sleep mode, and the power supply related to the X-ray image can be turned off. At this time, the mobile X-ray machine is in a sleep state. In addition, when the mobile X-ray machine is in a fully powered-on state and has not been used for a long time, it will also enter the sleep mode, and the control signal generating unit 232 in the main control module 230 will also turn off the power module in the imaging component power group 250 that is allowed to be turned off. Similarly, if the main control unit 230 receives a shutdown signal at this time, step S410 is executed.

[0097] Further, for step S421, it is determined that the working mode of the high voltage generator is mode 6, which is the charging standby mode. This mode turns on the main control module 230 based on mode 1, so that the standby power supply and the main control module 230 work simultaneously. At this time, the main control unit 230 can detect the charging state of the power supply module 210.

[0098] In the charging standby mode, there is no need to save power, and the status signal processing unit 231 operates in full.

[0099] When the high voltage generator is in mode 6, if the action signal received by the main control unit 230 is a half-startup signal, step S422 is executed.

[0100] Step S422, determine that the working mode of the high voltage generator is mode 7, which is a charging start mode, similar to mode 2. At this time, the mobile X-ray machine is in a charging state and cannot be moved before disconnecting the power grid connection line. Therefore, in this mode, the power module related to movement in the moving component power group 240 is turned off to ensure that the mobile X-ray machine will not be moved by mistake during the charging process of connecting to the mains.

[0101] When the high voltage generator is in mode 7, if the action signal received by the main control unit 230 is a full power-on signal, step S423 is executed.

[0102] Step S423, determine whether the battery power is lower than the second threshold. If yes, execute step S424. If no, execute step 425, i.e. mode 3-2.

[0103] Step S424, determine that the working mode of the high voltage generator is mode 8, which is a derating exposure mode, which is similar to mode 3-1 and mode 3-2, but limits the output power. At this time, the mobile X-ray machine cannot perform high-dose X-ray diagnosis, but can meet the requirements of daily ordinary diagnosis. In this mode, when the battery of the mobile X-ray machine is low and the user is eager to use it, conventional X-ray diagnosis can be performed while charging.

[0104] Similarly, in mode 8, if the main control unit 230 receives a shutdown signal, step S410 is executed. If the main control unit 230 receives a sleep signal, step S416 is executed to enter mode 4, i.e., sleep mode, and turn off the power related to the X-ray image. At this time, the mobile X-ray machine is in sleep mode.

[0105] Step S425, determine that the working mode of the high voltage generator is mode 3-2, and mode 3-2 is the battery charging process imaging component startup mode. In this mode, the control signal generation unit 232 in the main control module 230 will generate a control signal to turn on the imaging component power group 250, and the power supply related to the X-ray image and other function expansion power modules (power modules a~N) work. At this time, the mobile X-ray machine cannot be pushed but can perform X-ray diagnosis normally. That is, the imaging component power group 250 works, and the motor drive module 302 does not work to prevent the high voltage generator from moving.

[0106] Further, in mode 3-2, if the main control unit 230 receives a sleep signal, step S416 is executed, and if a shutdown signal is received, step S410 is executed. In some embodiments, mode 4 can also be divided into two modes according to whether the battery is being charged, such as a battery non-charging process sleep mode and a battery charging process sleep mode, wherein the battery charging process sleep mode generally ensures that the motor drive module 302 in the moving part power pack 250 is not working to prevent the high voltage generator from moving.

[0107] Among them, in the above embodiments, except for mode 1, all modes can flexibly switch each power module according to the needs of different mobile X-ray machines. In addition, in some embodiments, step S410 can be executed after receiving a shutdown signal in each mode, thereby entering the standby mode. For example, in some embodiments, S410 can be executed after receiving a shutdown signal in mode 2 and mode 7.

[0108] Among the above modes, only Mode 1, Mode 2, Mode 3-1 and Mode 3-2 are required basic modes. Mode 5 is also usually present. Mode 4 is an optional mode, and the mobile X-ray machine power management system decides whether to enter this mode based on whether it receives a sleep signal from the host system 260. Mode 6, Mode 7 and Mode 8 are all optional modes.

[0109] In the mobile X-ray machine power management system and control method thereof of the embodiment of the present invention, a main control module is provided. The main control module controls the operation of the functional component power group according to the action signal sent by the host computer and the status information of the power supply module, thereby improving the scientificity, reliability and flexibility of power management and reducing the power loss of the high-voltage generator.
