[0053] Color Doppler ultrasound equipment refers to devices used for ultrasound imaging, measurement, and blood flow information acquisition for clinical ultrasound diagnostic examinations. Color Doppler ultrasound equipment is powered by a power supply unit. Typically, color Doppler ultrasound equipment uses an adapter to connect to AC power to power the main unit. To address the issue of the equipment still operating without AC power, a separate main unit battery is added. This battery can power the equipment in the absence of AC power, extending its operating time. However, the limited capacity of the main unit battery restricts the equipment's battery life.

[0054] To address the aforementioned issues, this application provides a multi-power management system.

The host power management module selects the host battery, trolley battery, or adapter to power the host device based on the second control signal. This multi-power management system adds a trolley battery to the color Doppler ultrasound equipment and optimizes the power supply sequence of the adapter, trolley battery, and host battery, thereby improving the equipment's battery life.

[0055] To illustrate the technical solution described in this application, specific embodiments are provided below.

[0056] Figure 1 The diagram illustrates the principle block diagram of a multi-power management system provided in an embodiment of this application. The multi-power management system may include an adapter voltage detection module 300, a power-on detection module 400, a trolley power management module 500, a host power management module 600, a trolley battery 700, and a host battery 800. The trolley power management module 500 is connected to the adapter voltage detection module 300, the power-on detection module 400, and the trolley battery 700. The host power management module 600 is connected to the trolley power management module 500, the host battery 800, the host device 200, and the adapter 100. The adapter voltage detection module 300 is connected to the trolley battery 700 and the adapter 100.

[0057] Specifically, the adapter voltage detection module 300 detects the output voltage of the adapter 100 and the output voltage of the trolley battery 700, and generates a first control signal based on these voltages. The power-on detection module 400 detects the power-on current signal of the host device 200. The trolley power management module 500 controls the charging of the trolley battery 700 based on the first control signal and the power-on current signal, and sends a second control signal to the host power management module 600. The host power management module 600 selects the host battery 800, the trolley battery 700, or the adapter 100 to power the host device 200 based on the second control signal. The multi-power management system provided in this embodiment adds a trolley battery 700 to the color ultrasound equipment and optimizes the power supply sequence of the adapter 100, the trolley battery 700, and the host battery 800 on the color ultrasound equipment, thereby improving the endurance of the color ultrasound equipment.

[0058] Figure 2The schematic diagram of the multi-power management system provided in the embodiment of this application is shown. The adapter voltage detection module 300 may include an adapter voltage acquisition unit 302, a trolley battery voltage acquisition unit 301, and a voltage comparison unit 303. The adapter voltage acquisition unit 302 is connected to the adapter 100, the trolley battery voltage acquisition unit 301 is connected to the trolley battery 700, and the voltage comparison unit 303 is connected to the adapter voltage acquisition unit 302, the trolley battery voltage acquisition unit 301, and the trolley power management module 500, respectively.

[0059] Specifically, the adapter voltage acquisition unit 302 is used to acquire the output voltage of the adapter 100, the stroller battery voltage acquisition unit 301 is used to acquire the output voltage of the stroller battery 700, and the voltage comparison unit 303 is used to generate a first control signal based on the output voltage of the adapter 100 and the output voltage of the stroller battery 700, and transmit it to the stroller power management module 500.

[0060] For example, such as Figure 3 As shown, the adapter voltage acquisition unit 302 may include a first sampling resistor R175, the trolley battery voltage acquisition unit 301 may include a second sampling resistor R187, and the voltage comparison unit 303 may include a comparison chip U17 (taking BQ24610 as an example). The ACP port of the comparator chip U17 is connected to the output terminal of the adapter 100 through the first sampling resistor R175 to collect the output voltage of the adapter 100. The SRP port of the comparator chip U17 is connected to the output terminal of the trolley battery 700 through the second sampling resistor R187 to collect the output voltage of the trolley battery 700. When the voltage of the ACP port of the comparator chip U17 is greater than the voltage of the SRP port, it indicates that the adapter 100 can supply power normally. The comparator chip U17 outputs a first control signal to the trolley power management module 500. The trolley power management module 500 controls the adapter 100 to supply power to the host device 200 according to the first control signal. When the voltage of the ACP port of the comparator chip U17 is less than the voltage of the SRP port, it indicates that the adapter 100 cannot supply power normally. The comparator chip U17 outputs a first control signal to the trolley power management module 500. The trolley power management module 500 detects the power information of the trolley battery 700 according to the first control signal.

[0061] Figure 4 The schematic diagram of the multi-power management system provided in the embodiment of this application is shown. The power-on detection module 400 may include a current acquisition unit 401 and a current-to-voltage conversion unit 402. The current acquisition unit 401 is connected to the power interface 201 of the host device 200, and the current-to-voltage conversion unit 402 is connected to the current acquisition unit 401 and the trolley power management module 500, respectively.

[0062] Specifically, the current acquisition unit 401 is used to acquire the current signal of the host device 200, and the current-to-voltage conversion unit 402 is used to convert the current signal into a corresponding voltage signal and transmit the voltage signal to the trolley power management module 500.

[0063] For example, such as Figure 5 As shown, the current acquisition unit 401 may include a detection resistor R27, and the current-voltage conversion unit 402 may include a conversion chip U7 (taking INA1812IDBR as an example); the detection resistor R27 is connected to the power interface 201 of the host device 200, the first input terminal and the second input terminal of the conversion chip U7 are respectively connected to the two ends of the detection resistor R27, and the output terminal of the conversion chip U7 is connected to the trolley power management module 500.

[0064] Specifically, since there is no communication interface between the trolley power management module 500 and the host device 200, the power-on status of the host device 200 can be determined by detecting its standby and power-on operating current. The detection resistor R27 can be connected in series between the power supply (the MAIN_POWER port where the adapter 100, host battery 800, and trolley battery 700 are connected) and the host device 200 (the port XT30 where the host device 200 is connected). When the adapter 100 supplies power to the host device 200 and the trolley battery 700 supplies power to the host device... When the host device 200 is powered by the power supply 200 or the host battery 800, current will flow through the detection resistor R27. The first input terminal (IO+) and the second input terminal (IO-) of the conversion chip U7 are respectively connected to the two ends of the detection resistor R27. The conversion chip U7 converts the current signal collected by the detection resistor R27 into a corresponding voltage signal (output from the OUT port) and transmits the voltage signal to the trolley power management module 500. The trolley power management module 500 can identify the current state of the host device 200 (power-on state or standby state) based on the magnitude of the voltage signal.

[0065] Figure 6 The diagram shows a schematic block diagram of the multi-power management system provided in an embodiment of this application. The trolley power management module 500 includes a first controller 501, a first detection unit 502, and a first charging unit 503. The first controller 501 is connected to the first detection unit 502, the first charging unit 503, the adapter voltage detection module 300, the power-on detection module 400, and the host power management module 600. The first detection unit 502 and the first charging unit 503 are both connected to the trolley battery 700.

[0066] Specifically, the first detection unit 502 detects the power information of the stroller battery 700. After the adapter voltage detection module 300 identifies whether the adapter 100 is supplying power normally, it sends a first control signal to the first controller 501. When the adapter 100 is supplying power normally, the first controller 501 controls the first charging unit 503 to charge the stroller battery 700 according to the first control signal. When the adapter 100 is not supplying power, the first controller 501 determines whether the stroller battery 700 can supply power normally based on the power information of the stroller battery 700. If the stroller battery 700 has sufficient power to supply power, the first controller 502... A controller 501 controls the first charging unit 503 to stop charging the trolley battery 700, and simultaneously sends a second control signal to the host power management module 600; the host power management module 600 controls the host battery 800 to neither discharge nor charge according to the second control signal, and controls the trolley battery 700 to supply power to the host device 200; if the trolley battery 700 is too low to supply power, the first controller 501 sends a second control signal to the host power management module 600, and the host power management module 600 controls the host battery 800 to discharge according to the second control signal to supply power to the host device 200.

[0067] In one embodiment of this application, the first charging unit 503 is provided with multiple charging ports, and the trolley battery 700 may include multiple individual batteries, with each individual battery corresponding to one of the multiple charging ports.

[0068] Specifically, the first charging unit 503 can charge multiple individual batteries simultaneously or charge a single individual battery. By controlling the number of individual batteries being charged simultaneously, the first charging unit 503 can adjust the charging current to reduce the load on the power supply of the adapter 100, allowing the use of a lower-power adapter 100 to meet the needs of the host device 200. For example, when the adapter 100 is supplying power normally and the host device 200 is in standby mode, the first charging unit 503 charges all individual batteries (increasing the charging current); when the adapter 100 is supplying power normally and the host device 200 is powered on, the first charging unit 503 can charge only some of the individual batteries (reducing the charging current).

[0069] In one embodiment of this application, the trolley power management module 500 may further include a first charging current adjustment unit, which is connected to the first controller 501.

[0070] Specifically, in addition to controlling the number of individual cells being charged simultaneously, the charging current of the stroller battery 700 can also be controlled by generating a first adjustment signal through the first charging current adjustment unit and transmitting the first adjustment signal to the first controller 501. The first controller 501 controls the charging current of the first charging unit 503 to the stroller battery 700 according to the first adjustment signal, thereby achieving the adjustment of the charging current of the stroller battery 700. For example, when the adapter 100 is normally powered and the host device 200 is in standby mode, the first controller 501 increases the charging current of the first charging unit 503 to the stroller battery 700 according to the first adjustment signal; when the adapter 100 is normally powered and the host device 200 is in the powered-on state, the first controller 501 decreases the charging current of the first charging unit 503 to the stroller battery 700 according to the first adjustment signal.

[0071] Figure 7 The diagram shows a principle block diagram of the multi-power management system provided in an embodiment of this application. The host power management module 600 includes a second controller 601, a second detection unit 603, a second charging unit 602, and a discharging unit 604. The second controller 601 is connected to the trolley power management module 500, the second detection unit 603, the second charging unit 602, and the discharging unit 604, respectively. The second detection unit 603, the second charging unit 602, and the discharging unit 604 are all connected to the host battery 800. The discharging unit 604 is also connected to the host device 200, the trolley battery 700, and the adapter 100.

[0072] Specifically, when the adapter 100 is supplying power normally, the second controller 601 controls the second charging unit 602 to charge the main battery 800 and controls the discharging unit 604 to select the adapter 100 to supply power to the main device 200; when the adapter 100 cannot supply power normally, but the trolley battery 700 can supply power normally, the second controller 601 controls the second charging unit 602 to stop charging the main battery 800 and controls the discharging unit 604 to select the trolley battery 700 to supply power to the main device 200; when neither the adapter 100 nor the trolley battery 700 can supply power normally, the second controller 601 controls the second detection unit 603 to detect the power information of the main battery 800; when the power of the main battery 800 meets the power supply conditions, the second controller 601 controls the discharging unit 604 to release the electrical energy of the main battery 800 to supply power to the main device 200.

[0073] In one embodiment of this application, the host power management module 600 may further include a second charging current adjustment unit, which is connected to the second controller 601.

[0074] Specifically, the second charging current adjustment unit is used to generate a second adjustment signal and transmit the second adjustment signal to the second controller 601. The second controller 601 controls the charging current of the second charging unit 602 to the host battery 800 according to the second adjustment signal.

[0075] Figure 8 The diagram illustrates a workflow of a multi-power management system provided in an embodiment of this application. The workflow of the multi-power management system may include:

[0076] Step S8001: Identify whether adapter 100 is supplying power normally.

[0077] Specifically, the adapter voltage detection module 300 detects the output voltage of the adapter 100 and the output voltage of the stroller battery 700, and compares the output voltage of the adapter 100 and the output voltage of the stroller battery 700 to determine whether the adapter 100 is supplying power normally.

[0078] Step S8002: Under normal power supply from adapter 100, identify the working status of host device 200.

[0079] Specifically, the power-on detection module 400 detects the current information of the host device 200 and outputs the corresponding voltage information to the trolley power management module 500. The trolley power management module 500 identifies the working status (power-on state or standby state) of the host device 200 based on the voltage information.

[0080] In step S8003, when the adapter 100 is powered normally and the host device 200 is in standby mode, the adapter 100 is controlled to power the host device 200, the host battery 800 is charged, and the charging current of the trolley battery 700 is increased.

[0081] Specifically, when the adapter 100 is normally supplying power to the host and the host device 200 is in standby mode, the trolley power management module 500 increases the charging current to the trolley battery 700, and the host power management module 600 controls the charging of the host battery 800.

[0082] In step S8004, when the adapter 100 is powered normally and the host device 200 is powered on, the adapter 100 is controlled to power the host device 200, the host battery 800 is charged, and the charging current of the trolley battery 700 is reduced.

[0083] Specifically, when the adapter 100 is supplying power to the host normally and the host device 200 is powered on, the trolley power management module 500 reduces the charging current to the trolley battery 700, and the host power management module 600 controls the host battery 800 to charge and controls the adapter 100 to supply power to the host device 200.

[0084] Step S8005: If the adapter 100 cannot supply power normally, check whether the stroller battery 700 can supply power normally.

[0085] Specifically, when the adapter 100 is unable to supply power to the host device 200, the trolley power management module 500 detects the power information of the trolley battery 700 and determines whether the trolley battery 700 can supply power to the host device 200 based on the power information of the trolley battery 700.

[0086] In step S8006, if the adapter 100 cannot supply power normally, but the trolley battery 700 can supply power normally, control the trolley battery 700 to supply power to the host device 200, and prevent the host battery 800 from charging.

[0087] Specifically, when the adapter 100 fails to supply power normally, but the trolley battery 700 can supply power normally, the host power management module 600 controls the trolley battery 700 to supply power to the host device 200, while controlling the host battery 800 to prevent charging.

[0088] In step S8007, when neither the adapter 100 nor the trolley battery 700 can supply power normally, the main unit battery 800 is controlled to supply power to the main unit device 200.

[0089] Specifically, when neither the adapter 100 nor the trolley battery 700 can supply power normally, the host power management module 600 controls the host battery 800 to supply power to the host device 200.

[0090] The multi-power management system provided in this application embodiment adds a trolley battery 700 to the color ultrasound equipment and optimizes the power supply sequence of the adapter 100, trolley battery 700 and main unit battery 800 on the color ultrasound equipment, thereby improving the battery life of the color ultrasound equipment.

[0091] This application also discloses a color ultrasound device, which may include the multi-power management system described above. Compared with existing color ultrasound devices, the color ultrasound device in this application embodiment has better battery life.
