DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0031] The flowcharts shown in the drawings are only illustrative, and do not necessarily include all the contents and operations / steps, nor are they necessarily executed in the order described. For example, some operations / steps can be further decomposed, combined, or partially merged, so the actual execution order can be changed according to actual conditions.

[0032] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following examples and features in the examples can be combined with each other without conflict.

[0033] Please refer to Figure 1 and Figure 2 , Figure 1 and Figure 2 is a structural schematic diagram of an ultrasound imaging system provided by an embodiment of the present application. The ultrasound imaging system includes a power supply device 100 and an ultrasound imaging device 200. The power supply device 100 is capable of supplying power to the ultrasound imaging device 200.

[0034] In some embodiments, as shown in Figures 1 to 3 , the ultrasound imaging device 200 includes a device interface 210 and a load 220 for performing ultrasound imaging.

[0035] As shown in Figure 3 , the load 220 can include parts of the ultrasound imaging device 200 that consume power, such as an ultrasound probe 221, a mainboard 222, a display 223, etc. The mainboard 222 acquires ultrasound echo signals from the ultrasound probe 221, performs ultrasound imaging on the ultrasound echo signals to obtain an ultrasound image of a subject, and then transmits the ultrasound image to the display 223 for display.

[0036] It can be understood that the ultrasound imaging device 200 is used to emit ultrasound waves to a subject through the ultrasound probe 221, receive ultrasound echoes returned from the subject, perform ultrasound imaging on the ultrasound echo signals to obtain an ultrasound image of the subject, and then display the ultrasound image on the display 223.

[0037] Specifically, as shown in Figures 1 to 3 , the power supply device 100 includes a device interface 110, which is capable of being magnetically attracted to the device interface 210 of the ultrasound imaging device 200, so that the power supply device 100 is connected to the ultrasound imaging device 200.

[0038] As shown in Figure 4 is a cross-sectional schematic diagram when the device interface 110 and the device interface 210 are magnetically attracted.

[0039] Specifically, the device interface 110 and / or the equipment interface 210 is provided with a magnetic member to realize magnetic adsorption of the device interface 110 and the equipment interface 210. The magnetic member may, for example, include a ferrite magnet, an alnico magnet, a neodymium iron boron magnet, or an electromagnet, and the present application does not limit the same. When the magnetic member is an electromagnet, the electromagnet will not adsorb ferromagnetic substances when not powered, which can avoid the influence of ferromagnetic substances on the connection of the device interface 110 and the equipment interface 210, and the strength of the electromagnet can be adjusted by the current, so that the strength of the magnetic adsorption can be adjusted.

[0040] In some embodiments, as shown in Figure 3 and Figure 4 , the device interface 110 is provided with a first magnetic member 111, and the first magnetic member 111 is used for magnetic adsorption with the equipment interface 210 of the ultrasonic imaging equipment 200 to connect the device interface 110 to the ultrasonic imaging equipment 200. The power supply device 100 can be magnetically adsorbed with the equipment interface 210 through the first magnetic member 111 to connect the device interface 110 of the power supply device 100 to the ultrasonic imaging equipment 200 and supply power to the ultrasonic imaging equipment 200.

[0041] For example, the position of the equipment interface 210 corresponding to the first magnetic member 111 on the device interface 110 can be a material that can be adsorbed with the first magnetic member 111, for example, the position of the equipment interface 210 can be provided with a magnetic member of soft magnetic material, for example, a silicon steel sheet.

[0042] For example, as shown in Figure 3 and Figure 4 , the position of the equipment interface 210 corresponding to the first magnetic member 111 on the device interface 110 can also be provided with a second magnetic member 211, and the second magnetic member 211 is used for magnetic adsorption with the first magnetic member 111 on the device interface 110 to connect the equipment interface 210 to the device interface 110.

[0043] In other embodiments, as shown in Figure 3 and Figure 4 , the second magnetic member 211 can be provided on the equipment interface 210, and the position of the device interface 110 of the power supply device 100 corresponding to the second magnetic member 211 can be a material that can be adsorbed with the second magnetic member 211, for example, the position of the device interface 110 can be provided with a magnetic member of soft magnetic material, for example, a silicon steel sheet.

[0044] Specifically, as shown in Figure 3 , the power supply device 100 further includes a power supply circuit 120, and the power supply circuit 120 is used for outputting electric energy to the device interface 110.

[0045] In some embodiments, the power supply device 100 further includes a power adapter 140 , which is used to convert AC power into direct current (DC) power of a specific voltage, and can output the DC power to the device interface 110 through the power circuit 120 .

[0046] Figures 1 to 4 The ultrasonic imaging system shown connects the power supply device 100 and the ultrasonic imaging device 200 by magnetic adsorption, without the user having to plug and unplug with force. The device interface 110 and the device interface 210 can be connected in a shorter time, reducing the user's workload and making it easier for the user to use.

[0047] During magnetic connection, due to the high resistance of the magnetic interface at the moment of contact, hot plugging and unplugging may cause excessive local temperature rise, which may cause fire and damage the device. Figure 3 As shown, the ultrasound imaging system further provides a power control circuit 130 on the power supply device 100, so that when it is detected that the device interface 110 is connected to the equipment interface 210, the device interface 110 and the power circuit 120 are connected, so that the power supply device 100 can supply power to the outside.

[0048] For example, the power supply circuit 120 and the power control circuit 130 may be disposed near the power adapter 140, in the power adapter 140, on the power line between the power adapter 140 and the device interface 110, or may be disposed near the device interface 110. It will be appreciated that when the power supply circuit 120 and the power control circuit 130 are disposed near the device interface 110, wiring layout may be facilitated and reliability may be improved.

[0049] In some embodiments, as Figure 3 As shown, the power circuit 120 includes at least one of a first control switch 121, a power voltage regulator chip, and a voltage conversion circuit. The first control switch 121 may include a metal-oxide semiconductor field effect transistor (MOSFET), but the present application is not limited thereto.

[0050] Exemplarily, the first control switch 121 in the power supply circuit 120 is connected to the power supply control circuit 130, and the first control switch 121 is used to be controlled by the power supply control circuit 130 to be turned on so that the power supply circuit 120 outputs electrical energy to the device interface 110, or to be controlled by the power supply control circuit 130 to be turned off so that the power supply circuit 120 stops outputting electrical energy to the device interface 110.

[0051] For example, when the device interface 110 is not connected to the equipment interface 210, the power supply circuit 120 does not output power to the device interface 110, and the device interface 110 is not powered, thus no abnormal discharge sparking occurs when the device interface 110 is close to the equipment interface 210. After the device interface 110 is connected to the equipment interface 210, the first control switch 121 is turned on, and the power supply circuit 120 supplies power to the device interface 110, so that the equipment interface 210 can obtain power; in this process, the power supply device 100 supplies power to the ultrasonic imaging equipment 200 only after the power supply device 100 and the ultrasonic imaging equipment 200 have been successfully connected, and this process does not produce abnormal discharge sparking, and can avoid the large temperature rise caused by the large impedance of the magnetic adsorption connection method at the moment of interface contact, thus protecting the safety of the load 220 of the ultrasonic imaging equipment 200 and prolonging the service life.

[0052] Specifically, the power supply control circuit 130 can detect whether the device interface 110 is connected to the equipment interface 210, and control the power supply circuit 120 to supply power to the ultrasonic imaging equipment 200 through the device interface 110 when it is detected that the device interface 110 is connected to the equipment interface 210, for example, by controlling the first control switch 121 to be turned on so that the power supply circuit 120 outputs power to the device interface 110.

[0053] In some embodiments, the power supply control circuit 130 is further configured to control the power supply circuit 120 to stop outputting power to the device interface 110 when the device interface 110 is not connected to the equipment interface 210.

[0054] For example, the power supply control circuit 130 can also stop controlling the power supply circuit 120 to supply power to the ultrasonic imaging equipment 200 through the device interface 110 when it is detected that the device interface 110 is not connected to the equipment interface 210, for example, by controlling the first control switch 121 to be turned off so that the power supply circuit 120 stops outputting power to the device interface 110.

[0055] When the device interface 110 is not connected to the equipment interface 210, the power supply to the device interface 110 is stopped, and the device interface 110 is not electrified, which can prevent short-circuit discharge caused by foreign matter contacting the device interface 110.

[0056] In some possible embodiments, the power supply control circuit 130 is connected to the device interface 110 and the power supply circuit 120. The power supply control circuit 130 can establish a communication connection with the ultrasonic imaging equipment 200 when the device interface 110 is connected to the ultrasonic imaging equipment 200, and control the power supply circuit 120 to supply power to the ultrasonic imaging equipment 200 through the device interface 110 when the communication connection with the ultrasonic imaging equipment 200 has been established.

[0057] For example, as shown in FIG. 1, the power supply device 100 includes a power supply control circuit 130, a power supply circuit 120, and a device interface 110. Figure 3As shown, the main board 222 of the ultrasound imaging device 200 is connected to the device interface 210, and the power supply control circuit 130 can establish a communication connection with the main board 222 when the device interface 110 is connected to the device interface 210. Specifically, the power supply control circuit 130 can establish a communication connection with a processor on the main board 222.

[0058] In some embodiments, as shown in FIG. 1, the power supply control circuit 130 can establish a communication connection with the power supply management circuit 230 of the ultrasound imaging device 200. Figure 5 As shown, the ultrasound imaging device 200 further includes a power supply management circuit 230 connected between the device interface 210 and the load 220.

[0059] For example, the power supply management circuit 230 can be disposed on the main board 222 or on a circuit board independent of the main board 222.

[0060] For example, the power supply control circuit 130 can establish a communication connection with the power supply management circuit 230 of the ultrasound imaging device 200. For example, as shown in FIG. 1, the power supply management circuit 230 can include a device control circuit 231 that can establish a communication connection with the power supply control circuit 130. Figure 5

[0061] In some embodiments, the power supply control circuit 130 establishes a communication connection with the ultrasound imaging device 200 through a handshake protocol. For example, the power supply control circuit 130 can establish a communication connection with the ultrasound imaging device 200 through a three-way handshake process.

[0062] For example, when the device interface 110 is connected to the ultrasound imaging device 200, the power supply control circuit 130 sends a synchronization signal and an initial sequence number of the power supply device 100 to the ultrasound imaging device 200 through the device interface 210; after the ultrasound imaging device 200 receives the synchronization signal and the initial sequence number of the power supply device 100, the ultrasound imaging device 200 sends a synchronization signal and an initial sequence number of the ultrasound imaging device 200 to the power supply device 100 through the device interface 110; after the power supply device 100 receives the synchronization signal and the initial sequence number of the ultrasound imaging device 200, the power supply device 100 can determine that a communication connection has been established with the ultrasound imaging device 200. Through the handshake protocol, it can be determined whether a reliable communication connection has been established with the ultrasound imaging device 200, and when a reliable communication connection is established with the ultrasound imaging device 200, the power supply circuit 120 can supply power to the ultrasound imaging device 200 through the device interface 110. This can prevent abnormal discharge sparking and temperature rise between the device interface 110 and the device interface 210 when the device interface 110 and the device interface 210 are not reliably connected and power is supplied to the ultrasound imaging device 200 through the device interface 110.

[0063] ​For example, the power supply control circuit 130 establishes a communication connection with the ultrasound imaging device 200 and identifies the ultrasound imaging device 200 as a legal device, and the power supply control circuit 130 controls the power supply circuit 120 to output power to the device interface 110.

[0064] By establishing a communication connection, it is more convenient to determine whether the ultrasound imaging device 200 is a legal device. For example, whether the ultrasound imaging device 200 is a legal device can be identified by the verification code, physical address, etc. sent by the ultrasound imaging device 200.

[0065] For example, the legal device can be an ultrasound imaging device 200 that is compatible with the power supply voltage, current, and power of the power supply device 100. The power supply control circuit 130 controls the power supply circuit 120 to output power to the device interface 110 only when a communication connection is established with the ultrasound imaging device 200 and the ultrasound imaging device 200 is identified as a legal device. This can prevent damage to the normal operation and service life of the ultrasound imaging device 200 caused by incompatible power supply voltage, current, and power.

[0066] For example, the power supply control circuit 130 is also used to control the power supply circuit 120 to stop outputting power to the device interface 110 when a communication connection is not established with the ultrasound imaging device 200. For example, when the communication connection with the ultrasound imaging device 200 is disconnected, the power supply control circuit 120 stops outputting power to the device interface 110. When the power supply device 100 is unplugged from the ultrasound imaging device 200, the power supply control circuit 130 is disconnected from the ultrasound imaging device 200, and the power supply control circuit 130 can stop outputting power to the device interface 110 to prevent abnormal discharge sparking between the device interface 110 and the device interface 210.

[0067] In other possible embodiments, as shown in Figures 6 to 8 The device interface 110 of the power supply device 100 and / or the device interface 210 of the ultrasound imaging device 200 is provided with a distance sensor 10.

[0068] For example, the distance sensor 10 includes at least one of an optical sensor, an infrared sensor 11, an ultrasonic sensor, a capacitive sensor, a laser sensor, a radar sensor, a magnetic control switch, a Hall sensor 12, and a micro switch.

[0069] In some embodiments, as shown in Figure 6 and Figure 7 The device interface 110 of the power supply device 100 is provided with a distance sensor 10, and the distance sensor 10 is used to output during the connection process of the device interface 110 and the device interface 210.

[0070] For example, the power supply control circuit 130 is connected with the power supply circuit 120 and the distance sensor 10, and the power supply control circuit 130 is used to detect the output of the distance sensor 10, and control the power supply circuit 120 to supply power to the ultrasonic imaging device 200 through the device interface 110 according to the output of the distance sensor 10.

[0071] For example, as shown in FIG. 1, the device interface 110 is provided with an infrared sensor 11, and the infrared sensor 11 emits infrared rays to the device interface 210 or the area near the device interface 210, the device interface 210 or the area near the device interface 210 reflects the infrared rays, the infrared sensor 11 receives the reflected infrared rays, and outputs a first electrical signal. When the device interface 110 is not connected with the device interface 210, the infrared sensor 11 cannot receive the reflected infrared rays, and outputs a second electrical signal different from the first electrical signal. Therefore, whether the device interface 110 is connected with the device interface 210 can be determined according to the output of the distance sensor 10. When it is determined that the device interface 110 is connected with the device interface 210, the power supply circuit 120 can be controlled to supply power to the ultrasonic imaging device 200 through the device interface 110. Figure 6 For example, the infrared sensor 11 can measure the distance between the device interface 210 and the device interface 110 through the speed of the infrared rays propagating in the air and the time difference from the emission to the reception of the infrared rays, and determine whether the device interface 110 is connected with the device interface 210 according to the distance. When it is determined that the device interface 110 is connected with the device interface 210, the power supply circuit 120 can be controlled to supply power to the ultrasonic imaging device 200 through the device interface 110.

[0072] For example, the device interface 110 is provided with a micro switch, when the device interface 110 is close to the device interface 210 to reach a connected state, the micro switch is pressed to change the switch state of the micro switch, and the power supply control circuit 130 can determine whether the device interface 110 is connected with the device interface 210 according to the switch state of the micro switch. When it is determined that the device interface 110 is connected with the device interface 210, the power supply circuit 120 can be controlled to supply power to the ultrasonic imaging device 200 through the device interface 110.

[0073] For example, as shown in FIG. 1, the device interface 110 is provided with an infrared sensor 11, and the infrared sensor 11 emits infrared rays to the device interface 210 or the area near the device interface 210, the device interface 210 or the area near the device interface 210 reflects the infrared rays, the infrared sensor 11 receives the reflected infrared rays, and outputs a first electrical signal. When the device interface 110 is not connected with the device interface 210, the infrared sensor 11 cannot receive the reflected infrared rays, and outputs a second electrical signal different from the first electrical signal. Therefore, whether the device interface 110 is connected with the device interface 210 can be determined according to the output of the distance sensor 10. When it is determined that the device interface 110 is connected with the device interface 210, the power supply circuit 120 can be controlled to supply power to the ultrasonic imaging device 200 through the device interface 110.

[0074] Figure 7 ​As shown, the device interface 110 is provided with a magnetic control switch and / or a Hall sensor 12, and the device interface 210 of the ultrasonic imaging device 200 is provided with a magnetic member, which can be a magnetic member 13 independent of the second magnetic member 211, or can be the second magnetic member 211 itself. For example, the magnetic control switch and / or the Hall sensor 12 are positioned on the device interface 110 in correspondence with the position of the magnetic member on the device interface 210, so that when the device interface 110 is close to the device interface 210 to reach a connected state, the switching state of the magnetic control switch and / or the output of the Hall sensor 12 changes, and the power supply control circuit 130 can determine whether the device interface 110 is connected to the device interface 210 according to the switching state change of the magnetic control switch and / or the output change of the Hall sensor 12. When it is determined that the device interface 110 is connected to the device interface 210, the power supply circuit 120 can be controlled to supply power to the ultrasonic imaging device 200 through the device interface 110.

[0075] In some other embodiments, as shown in Figure 8 The device interface 210 of the ultrasonic imaging device 200 is provided with a distance sensor 10. The distance sensor 10 is used to output distance information between the device interface 210 and the device interface 110 or information related to the distance information during the connection of the device interface 210 and the device interface 110.

[0076] For example, as shown in Figure 5 and Figure 7 The power management circuit 230 can connect the path through which the device interface 210 supplies power to the load 220 according to the output of the distance sensor 10. When it is not detected by the distance sensor 10 that the device interface 210 is connected to the device interface 110, the power management circuit 230 can disconnect the electrical connection between the device interface 210 and the load 220. Thus, it can be achieved that when the device interface 110 of the power supply device 100 is pulled out from the device interface 210 of the ultrasonic imaging device 200, the connection between the device interface 210 and the load 220 is disconnected, preventing the stored electrical energy in the capacitance, inductance, etc. in the load 220 from being transmitted to the device interface 210, so that the problem of interface sparking occurs when the device interface 210 and the device interface 110 of the power supply device 100 are separated. It can also prevent the energy discharged from the live equipment such as the power supply device 100 from being conducted to the load 220 to cause damage to the load 220 when the live equipment abnormally discharges to the device interface 210.

[0077] For example, as shown in Figure 5 and Figure 7 The power management circuit 230 includes a second control switch 232 connected between the device interface 210 and the load 220, which is used to controllably switch between the on and off states to connect or disconnect the path through which the device interface 210 outputs electrical energy to the load 220.

[0078] In some other feasible embodiments, the power control circuit 130 is connected to the device interface 110, the power circuit 120 and the distance sensor 10, and the power control circuit 130 can establish a communication connection with the ultrasonic imaging device 200 when the device interface 110 is connected to the ultrasonic imaging device 200.

[0079] For example, when a communication connection is established with the ultrasonic imaging device 200, the power control circuit 130 controls the power circuit 120 to supply power to the ultrasonic imaging device 200 through the device interface 110 based on the output of the distance sensor 10. This can improve the accuracy of detecting whether the device interface 110 is connected to the device interface 210.

[0080] In some embodiments, as Figure 3 and Figure 9 As shown, the power supply device 100 and / or the ultrasonic imaging device 200 further includes a human-machine interaction device 20. Exemplarily, the human-machine interaction device 20 includes at least one of a mechanical switch, a touch switch, a sound detection device, a vibration detection device, and a gesture recognition device. The human-machine interaction device 20 can generate outputs based on user control operations. For example, mechanical switches and touch switches can switch states based on a user's press or touch, a sound detection device can generate outputs based on the user's voice control, and a gesture recognition device can detect the user's gesture type and generate outputs when the detected gesture type matches a preset type.

[0081] Illustratively, the power supply device 100 includes a human-machine interaction device 20, which is connected to a power control circuit 130. The power control circuit 130 is further configured to control the power supply circuit 120 to power the ultrasonic imaging device 200 via the device interface 110 based on user control operations on the human-machine interaction device 20. For example, after docking the device interface 110 of the power supply device 100 with the device interface 210 of the ultrasonic imaging device 200, the user can control the human-machine interaction device 20 so that the power control circuit 130 controls the power supply circuit 120 to power the ultrasonic imaging device 200 via the device interface 110 based on the output of the human-machine interaction device 20, thereby achieving manual power-on.

[0082] Exemplarily, the ultrasonic imaging device 200 includes a human-computer interaction device 20. For example, the mainboard 222 or the power management circuit 230 of the ultrasonic imaging device 200 can receive the output of the human-computer interaction device 20, and output corresponding instructions to the power control circuit 130 of the power supply device 100 according to the output of the human-computer interaction device 20, so that the power control circuit 130 controls the power circuit 120 to power the ultrasonic imaging device 200 through the device interface 110 according to the instruction, that is, manual power-on can be achieved.

[0083] In some embodiments, asFigure 9 As shown, the power control circuit 130 of the power supply device 100 and / or the power management circuit 230 of the ultrasonic imaging apparatus 200 includes a power-on control circuit 30 .

[0084] Illustratively, the power management circuit 230 includes a power-on control circuit 30. The power-on control circuit 30 is configured to gradually increase the voltage and / or current output by the device interface 210 to the load 220 to the rated voltage and / or rated current when the power supply apparatus 100 supplies power to the ultrasonic imaging device 200. This further prevents the ultrasonic imaging device 200 from being impacted by a sudden surge in voltage and / or current supplied by the device interface 210 to the load 220.

[0085] Exemplarily, the power control circuit 130 of the power supply device 100 includes a power-on control circuit 30. The power-on control circuit 30 is configured to control the voltage and / or current outputted from the device interface 110 to the equipment interface 210 to gradually increase to the rated voltage and / or rated current when the first control switch 121 is turned on. For example, the power-on control circuit 30 may control the voltage and / or current outputted from the device interface 110 to the equipment interface 210 to gradually increase from zero to the rated voltage and / or rated current.

[0086] Exemplarily, the power-on control circuit 30 of the power supply device 100 controls the operating state of the first control switch 121 to gradually transition from the linear region to the saturation region. When the first control switch 121 operates in the linear region, the voltage and / or current output from the device interface 110 to the equipment interface 210 gradually increases. When the first control switch 121 operates in the saturation region, it is fully turned on, and the voltage and / or current output from the device interface 110 to the device interface 210 reaches the rated voltage and / or rated current.

[0087] It is understood that by gradually increasing the voltage and / or current outputted from the device interface 110 to the equipment interface 210 to the rated voltage and / or rated current, abnormal spark discharges can be further prevented when the device interface 110 and the equipment interface 210 are connected. Furthermore, the impact on the ultrasonic imaging device 200 caused by the sudden access of a high voltage and / or current to the equipment interface 210 can be avoided.

[0088] In some embodiments, as Figure 9 As shown, the power control circuit 130 of the power supply device 100 and / or the power management circuit 230 of the ultrasonic imaging apparatus 200 includes a delay circuit 40 .

[0089] For example, the power management circuit 230 includes a delay circuit 40 for connecting the device interface 210 to output power to the load 220 after a preset time period when the power supply device 100 supplies power to the ultrasonic imaging device 200.

[0090] For example, the power management circuit 230 includes a delay circuit 40 for connecting the device interface 210 to output power to the load 220 after a preset time period when the power supply device 100 supplies power to the ultrasonic imaging device 200.

[0091] In some embodiments, the power management circuit 230 can detect that the voltage and / or current output by the device interface 210 is not less than a preset connection threshold, and connect the device interface 210 to output power to the load 220 to supply power to the load 220 when it is detected that the voltage and / or current output by the device interface 210 is not less than the preset connection threshold.

[0092] For example, when the power supply device 100 detects that the device interface 110 is connected to the ultrasonic imaging device 200, the device interface 110 supplies power to the device interface 210 through the device interface 110. At this time, the power management circuit 230 can detect the voltage and / or current output by the device interface 210.

[0093] If the voltage and / or current output by the device interface 210 reaches the preset connection threshold, for example, the connection threshold is 70%-100% of the rated voltage and / or rated current of the load 220, it can be indicated that the device interface 110 and the device interface 210 are stably connected, and the power management circuit 230 controls the second control switch 232 to be turned on to enable the device interface 210 to provide power to the load 220.

[0094] In some embodiments, the voltage and / or current output by the device interface 110 to the device interface 210 gradually rises to the rated voltage and / or rated current, and the power management circuit 230 detects that the voltage and / or current output by the device interface 210 is also gradually rising, and when the voltage and / or current output by the device interface 210 rises to the connection threshold, the device interface 210 can provide power to the load 220. It can prevent the device interface 210 from suddenly providing a large voltage and / or current to the load 220 to shock the ultrasonic imaging device 200.

[0095] For example, the power management circuit 230 is configured to disconnect the power path from the device interface 210 to the load 220 when the voltage and / or current output by the device interface 210 is less than a preset connectivity threshold.

[0096] When the voltage and / or current output by the device interface 210 is less than the preset connectivity threshold, it is determined that the connection between the device interface 210 and the device interface 110 of the power supply device 100 is disconnected or unstable, and thus the load 220 cannot be supplied with required power. In this case, the load 220 is protected by disconnecting the device interface 210 from the load 220.

[0097] For example, during the process of releasing the magnetic attraction between the device interface 110 and the device interface 210, the voltage and / or current output by the device interface 210 decreases with the releasing operation. The power management circuit 230 detects the voltage and / or current output by the device interface 210, and controls the second control switch 232 to be disconnected when the voltage and / or current output by the device interface 210 is less than the preset connectivity threshold, so as to disconnect the device interface 210 from the load 220 before the magnetic attraction between the first magnetic member 111 and the second magnetic member 211 is released.

[0098] In some embodiments, as shown in FIG. 1, the power control circuit 130 of the power supply device 100 and / or the power management circuit 230 of the ultrasonic imaging device 200 comprises a sampling circuit 50. Figure 9

[0099] For example, the power management circuit 230 comprises the sampling circuit 50, which is configured to detect the current output by the device interface 210 to the load 220, and disconnect the power path from the device interface 210 to the load 220 when the current output by the device interface 210 to the load 220 is not less than an overcurrent threshold. For example, the sampling circuit 50 comprises a sampling resistor arranged between the device interface 210 and the load 220. The power management circuit 230 detects the sampling current transmitted by the device interface 210 to the load 220 through the sampling circuit 50, and controls the second control switch 232 to be disconnected when the sampling current of the device interface 210 is not less than the overcurrent threshold. Thus, overcurrent protection of the ultrasonic imaging device 200 can be achieved. For example, when the load 220 is short-circuited, the current transmitted by the device interface 210 to the load 220 exceeds the overcurrent threshold. The second control switch 232 is controlled to be disconnected, so as to stop transmitting power to the load 220, and thus the load 220 is protected from overcurrent damage.

[0100] ​For example, the power supply control circuit 130 of the power supply device 100 includes a sampling circuit 50 for detecting the current supplied by the power supply circuit 120 to the device interface 110, and when the current supplied by the power supply circuit 120 to the device interface 110 is not less than the overcurrent threshold, the power supply control circuit 130 controls the power supply circuit 120 to stop supplying power to the device interface 110. For example, the sampling circuit 50 includes a sampling resistor arranged between the power supply circuit 120 and the device interface 110. Thus, overcurrent protection can be achieved. For example, when there is a foreign object on the device interface 110 causing a short circuit, the current sampled by the power supply circuit 120 to the device interface 110 exceeds the overcurrent threshold, and the first control switch 121 is controlled to be turned off to stop transmitting power to the device interface 110, thereby avoiding damage to the power supply device 100 caused by overcurrent.

[0101] The ultrasonic imaging device, the power supply device thereof, and the ultrasonic imaging system provided by the embodiments of the present application are connected by magnetic attraction, without the need for the user to forcefully plug in or pull out. Moreover, the device interface of the power supply device and the device interface of the ultrasonic imaging device can be connected in a shorter time, reducing the working intensity of the user and facilitating the use of the user. In addition, the power supply circuit of the power supply device supplies power to the interface only when the device interface and the device interface are connected, which can avoid the large temperature rise and abnormal discharge sparking caused by the large impedance of the connection mode of plugging in and pulling out of the socket at the moment of contact of the interface, thereby prolonging the service life.
