Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical equipment, and in particular to a power consumption control method, a handheld ultrasonic device and an ultrasonic system. Background Art
[0002] In traditional ultrasound equipment, ultrasound equipment mainly includes ultrasound host and ultrasound probe. The ultrasound host processes ultrasound data and displays the processed ultrasound data on the monitor in the form of ultrasound images as the basis for clinical detection. The ultrasound probe is a system that transmits and receives ultrasound during the ultrasound detection process. Traditional ultrasound equipment has various problems such as large size, high price, heavy weight, and inconvenient movement, which cannot meet the application requirements of outdoor, emergency vehicles and other mobile scenarios. As a result, handheld ultrasound came into being, and it is mainly 32-channel.
[0003] Handheld ultrasound integrates some functions of traditional ultrasound host into the probe, that is, the probe can process ultrasound data, and then upload the processed ultrasound data to a tablet or mobile phone through wired or wireless form, and then further optimize the ultrasound data on the tablet / mobile phone and display it on the tablet or mobile phone screen. It can be seen that handheld ultrasound plus a tablet or mobile phone can obtain ultrasound images, greatly reducing the overall weight and volume, and is easy to carry. It has a wide range of market scenarios in mobile medical fields such as outdoor and emergency vehicles.
[0004] However, since the handheld ultrasonic device integrates high-power devices such as data processing and data transmission, the power consumption of the handheld ultrasonic device is relatively large, which affects the detection performance of the device. Summary of the invention
[0005] In view of this, the present invention provides a power consumption control method, a handheld ultrasonic device and an ultrasonic system to solve the problem that the existing handheld ultrasonic device consumes a large amount of power, thereby affecting the detection performance of the device.
[0006] In a first aspect, the present invention provides a power consumption control method, the method comprising:
[0007] Monitor the communication status between the local computer and the host computer;
[0008] If the communication state is unconnected, controlling the local to be powered on and at least one of the remaining modules in the handheld ultrasound device to be powered off, the local being the control module in the handheld ultrasound device, and the remaining modules including the modules in the handheld ultrasound device except the control module;
[0009] If the communication status is connected, the local power-on and at least one of all the remaining modules are controlled to be powered on to perform ultrasonic scanning on the target object.
[0010] The power consumption control method provided by the embodiment of the present invention can control the local power-on and at least one of the remaining modules in the handheld ultrasound device to be off-powered when the communication state between the local and the host computer is unconnected after the handheld ultrasound device is started. This is because in actual application scenarios, the time from pressing the power button to starting the operation of connecting the handheld ultrasound probe on the host computer can be as short as a few seconds or as long as tens of minutes or even longer, because during this period, the user may do irrelevant work, and the time taken by the host computer to connect the handheld ultrasound probe also varies with the actual use environment. If all modules of the handheld ultrasound device are powered on at this time, a large amount of power consumption will be lost. By controlling at least one of the remaining modules in the handheld ultrasound device to be off-powered during this period, the purpose of saving power consumption can be achieved; if the communication state is connected, the local power-on and at least one of all the remaining modules are controlled to be powered on to perform ultrasonic scanning on the target object, so that the average power consumption of the handheld ultrasound device can be controlled at a lower level, that is, on the basis of improving the performance of the device, the heat dissipation effect of the handheld ultrasound device in a small size is guaranteed, and only a small-capacity battery is required to ensure the working time of the device, thereby improving the standby time of the product.
[0011] In some optional embodiments, if the communication state is connected, after controlling the local power-on and at least one of all the remaining modules to be powered on to perform an ultrasonic scan on the target object, the method further includes:
[0012] receiving a control signal for controlling the local area;
[0013] If the control signal is a freeze signal, at least one of all the remaining modules is controlled to be powered off.
[0014] The power consumption control method provided in the embodiment of the present invention controls at least one of all the remaining modules to be powered off by receiving a control signal, thereby ensuring that the power consumption of the handheld ultrasound device is controlled according to demand.
[0015] In some optional implementations, if the control signal is a freeze signal, controlling at least one of all the remaining modules to be powered off includes:
[0016] Obtaining a first total power consumption of the local module and all the remaining modules;
[0017] When the first total power consumption is greater than the first power consumption threshold, at least one of all the remaining modules is controlled to be powered off.
[0018] The power consumption control method provided in an embodiment of the present invention can achieve the purpose of saving power consumption by controlling the power consumption of a handheld ultrasound device by controlling at least one of all the remaining modules to be powered off when the first total power consumption of the local and all the remaining modules is greater than the first power consumption threshold.

[0021] The power consumption control method provided by the embodiment of the present invention controls at least one of the remaining modules to be powered on when the control signal is a thawing signal, so as to collect ultrasonic images.
[0022] In some optional implementations, if the control signal is a thawing signal, controlling at least one of all the remaining modules to be powered on includes:
[0023] Obtaining a second total power consumption of the local module and the remaining powered-on modules;
[0024] When the second total power consumption is greater than the first power consumption threshold and less than the second power consumption threshold, at least one of the remaining modules that are not powered on is controlled to be powered on, so that the second total power consumption is greater than or equal to the second power consumption threshold.
[0025] The power consumption control method provided in the embodiment of the present invention controls at least one of the remaining modules that are not powered on to be powered on based on the second total power consumption of the local and other powered-on modules when the control signal is a thawing signal, so as to collect ultrasonic images.
[0026] In some optional embodiments, if the communication state is connected, after controlling the local power-on and at least one of all the remaining modules to be powered on to perform an ultrasonic scan on the target object, the method further includes:
[0027] Detecting the operating temperature or operating time of all the remaining modules;
[0028] If the operating temperature or the operating duration reaches a corresponding first preset value, at least one of the remaining powered-on modules is controlled to be powered-off.
[0029] The power consumption control method provided in the embodiment of the present invention controls power consumption through operating temperature or operating time to avoid power consumption loss caused by high operating temperature or excessively long operating time. When the operating temperature or operating time of the handheld ultrasonic device reaches the corresponding first preset value, at least one of the remaining powered-on modules is controlled to be powered-off, so that the average power consumption of the handheld ultrasonic device can be controlled at a lower level, further reducing the power consumption of the handheld ultrasonic device.
[0030] In some optional implementations, if the operating temperature or the operating duration reaches the corresponding first preset value, after controlling at least one of the remaining powered-on modules to be powered-off, the method further includes:
[0031] Detecting the current operating temperature or power-off duration of all the remaining modules;
[0032] If the current operating temperature meets a second preset value or the power-off time reaches a preset time, at least one of all the remaining modules is controlled to be powered on.

[0059] In some optional embodiments, the second sub-control may be a thaw physical button on the handheld ultrasound device.
[0060] In some optional embodiments, when the handheld ultrasonic device is in a normal scanning and image outputting state; that is, the user presses the freeze button (first sub-control) in the scanning and image outputting state, wherein the freeze button may be a physical button for freezing on the handheld ultrasonic device, or the same button may be used for freezing and unfreezing; the first control module on the handheld ultrasonic device detects a freeze signal; after the first control module detects the freeze signal, the control power module does not power on the second control module, the transmitting module, the receiving module and other modules; the handheld ultrasonic device enters a frozen state, at which time only the first control module of the handheld ultrasonic device is still in working state, and the second control module, the transmitting module, the receiving module and other modules are all in a power-off state, and the power consumption at this time is only the rated power consumption of the first control module, so the power consumption of the handheld ultrasonic device is at an extremely low level at this time, thereby effectively reducing the average power consumption of the handheld ultrasound.
[0061] In some optional embodiments, when the handheld ultrasonic device is in a frozen state, the user presses a thaw button (second sub-control), where the solution button can be a physical thaw button on the handheld ultrasonic device, or the same button can be used for thawing and freezing; the first control module on the handheld ultrasonic device detects a thaw signal; after the first control module detects the thaw signal, the control power module powers on the second control module, the transmitting module, the receiving module and other modules; the handheld ultrasonic device is powered on and completes power-on initialization; the handheld ultrasonic device returns to a normal scanning and image output state.
[0062] The handheld ultrasound device provided by the embodiment of the present invention controls the second control module and at least one of the functional modules to be powered off by sending a freeze signal, so that the average power consumption of the handheld ultrasound device can be controlled at a low level, thereby ensuring the heat dissipation effect of the handheld ultrasound device in a small size, and only a small-capacity battery is required to ensure the working time of the device, thereby improving the standby time of the product; in addition, since the handheld ultrasound device is no longer limited by heat dissipation and energy consumption, the number of ultrasound channels can be set to 6, 128 or more, thereby improving the acquisition effect of ultrasound images.

The receiving module is used to receive the echo signal output by the sound head. Among them, the functions of the first control module and the second control module can be integrated in one module, and are collectively referred to as control modules.
[0064] According to an embodiment of the present invention, an embodiment of a power consumption control method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.
[0065] In this embodiment, a power consumption control method is provided, which can be used for the above-mentioned handheld ultrasound device. The handheld ultrasound device includes a first control module, a second control module and a functional module. The first control module is used to communicate with the host computer and control the power-on status of the second control module and the functional module. The second control module is used to control the functional module to obtain an ultrasound image, wherein the functions of the first control module and the second control module can be integrated into one module, and are collectively referred to as a control module. Figure 3 is a flow chart of a power consumption control method according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:
[0066] Step S301, monitoring the communication status between the local computer and the host computer.
[0067] As described above, after the handheld ultrasonic device is started, the control module in the handheld ultrasonic device is powered on locally, that is, the control module in the handheld ultrasonic device is powered on, and the communication status between the local device and the host computer is monitored, thereby achieving low power consumption control of the handheld ultrasonic device.
[0068] Step S302, if the communication state is unconnected, controlling the local to be powered on and at least one of the remaining modules in the handheld ultrasound device to be powered off, the local being the control module in the handheld ultrasound device, and the remaining modules including the modules in the handheld ultrasound device except the control module;
[0069] In some optional embodiments, the communication status between the local and the host computer in the handheld ultrasound device, or the communication status between the first control module in the handheld ultrasound device and the host computer is monitored; if the communication status is disconnected, it is determined that the current power consumption mode is the first power consumption mode, and the local is controlled to be powered on and at least one of the remaining modules in the handheld ultrasound device is not powered on.
[0070] The power consumption control method provided by the embodiment of the present invention monitors the communication status with the host computer, and only when the communication status is connected, determines that the current power consumption mode is the second power consumption mode, and determines that it is the first power consumption mode in the unconnected state. Because in the first power consumption mode, the second control module and at least one of the functional modules are not powered on. This is because in actual application scenarios, the time from pressing the power button to starting to operate the host computer to connect the handheld ultrasound probe is as short as a few seconds and as long as tens of minutes or even longer, because during this period the user may do irrelevant work, and the time taken by the host computer to connect the handheld ultrasound probe also varies with the actual use environment. If all modules of the handheld ultrasound device are powered on at this time, a large amount of power consumption will be lost. The first power consumption mode can control the second control module and at least one of the functional modules (i.e., the remaining modules) to be powered off during this period, thereby achieving the purpose of saving power consumption.
[0071] Step S303: If the communication status is connected, control the local power-on and at least one of all the remaining modules to be powered on to perform ultrasonic scanning on the target object.
[0072] As mentioned above, by monitoring the communication status between the local and host computer as connected, controlling the local power-on and at least one of all the remaining modules to be powered on, the handheld ultrasound device can enter the normal working state of scanning and outputting images in time, thereby realizing low power consumption control of the handheld ultrasound device.
[0073] In some optional embodiments, if the communication status is connected, the local power is controlled to be powered on and at least one of the remaining modules is powered on to perform an ultrasonic scan on the target object, and the operating temperature or operating time of all the remaining modules can also be detected; if the operating temperature or the operating time reaches the corresponding first preset value, at least one of the remaining modules that have been powered on is controlled to be powered off, which can prevent the handheld ultrasound temperature from being too high and can quickly recover to the normal range or prevent the user from failing to enter the frozen state in time after the scanning is completed, thereby wasting power.
[0074] The power consumption control method provided in the embodiment of the present invention controls power consumption through operating temperature or operating time to avoid power consumption loss caused by high operating temperature or excessively long operating time. When the operating temperature or operating time of the handheld ultrasonic device reaches the corresponding first preset value, at least one of the remaining powered-on modules is controlled to be powered-off, so that the average power consumption of the handheld ultrasonic device can be controlled at a lower level, further reducing the power consumption of the handheld ultrasonic device.
[0075] In some optional embodiments, if the operating temperature or the operating duration reaches a corresponding first preset value, after controlling at least one of the remaining modules that are powered on to be powered off, the current operating temperature or power-off duration of all the remaining modules can also be detected; if the current operating temperature meets a second preset value or the power-off duration reaches a preset duration, control at least one of the remaining modules to be powered on.
[0076] The power consumption control method provided in an embodiment of the present invention controls at least one of all the remaining modules to be powered on when the current operating temperature of the handheld ultrasound device meets the second preset value or the sleep time reaches the preset sleep time, so that the handheld ultrasound device can enter the normal working state of scanning and outputting images in time.
[0077] During specific implementation, the handheld ultrasonic device is in a normal scanning and image outputting state; after the first control module detects that the temperature of the handheld ultrasonic device exceeds the standard or the continuous working time of the handheld ultrasonic device reaches the upper limit, it immediately controls the power module to power off the second control module, the transmitting module, the receiving module and other modules; after the second control module, the transmitting module, the receiving module and other modules are powered off, the handheld ultrasonic device enters a standby sleep state; after the handheld ultrasonic device enters the sleep state, the temperature will gradually decrease over time. When the first control module detects that the temperature of the handheld ultrasonic device returns to the normal range or the standby sleep time of the handheld ultrasonic device reaches the standard, it controls the power module to power on the second control module, the transmitting module, the receiving module and other modules; the handheld ultrasonic device is powered on and completes the power-on initialization, and the handheld ultrasonic device returns to a normal scanning and image outputting state.
[0078] Among them, the purpose of the standby sleep low power consumption control is to prevent the temperature of the handheld ultrasonic device from being too high, and to quickly restore it to the normal range or to prevent the user from failing to operate the handheld ultrasound in time after the scanning is completed, and entering the frozen state, causing waste of power consumption. When the first control module detects that the temperature of the handheld ultrasonic device exceeds the standard or the continuous working time of the handheld ultrasonic device reaches the upper limit, the power supply module is controlled to power off the second control module, the transmitting module, the receiving module and other modules, so that the handheld ultrasonic device enters the standby sleep state. At this time, only the first control module is in the working state, so that the handheld ultrasonic device is in an extremely low power consumption level, and the temperature of the handheld ultrasonic device can be quickly reduced to the normal range. When the handheld ultrasonic device is stably restored to the normal range or the sleep time reaches the upper limit, the first control module controls the power supply module to power on the second control module, the transmitting module, the receiving module and other modules, and automatically exits the sleep state and enters the normal scanning state.
[0079] During the specific implementation, the power button is pressed; the first control module is powered on and initialized; when the user connects the handheld ultrasound device via WIFI on the host computer and the connection is successful; after the first control module detects that the handheld ultrasound device is successfully connected to the host computer via WIFI, it starts to control the power-on timing of the power module to power on the second control module, the transmitting module, the receiving module and other modules respectively; the second control module, the transmitting module and the receiving module are powered on and power-on initialization is completed; after the whole machine is powered on and initialized, it starts scanning and real-time ultrasound images can be seen on the host computer.
[0080] Among them, the purpose of power-on low power consumption control is to avoid power consumption loss in the interval time from when the power button is pressed to when the user connects to the handheld ultrasound device via WIFI. In actual application scenarios, the time from when the user presses the power button to when the user starts to operate WIFI on the host computer to connect to the handheld ultrasound device is as short as a few seconds, or as long as tens of minutes or even longer, because the user may do other unrelated work during this period, and the time taken by the host computer to connect to the handheld ultrasound device via WIFI also varies with the actual use environment. If all modules of the whole machine are powered on at this time, a large amount of power consumption will be lost. However, through power-on low power consumption control, only the first control module can be powered on during this period, and other modules are not powered on. At this time, the power consumption is only the rated power consumption of the first control module, and the rated power consumption of the first control module itself is extremely low, so the purpose of saving power consumption can be achieved. Only after the user operates WIFI on the host computer to connect to the handheld ultrasound device, other modules start to power on and the whole machine starts to scan and output images.
[0081] In some optional implementations, the number of channels of the transmitting module and the receiving module may be 64 channels, 128 channels, or more channels.
[0082] The power consumption control method provided in this embodiment can control the second control module and the functional module when the control module is powered on and establishes a communication connection with the host computer after the handheld ultrasonic device is started, that is, at least one of the remaining modules is not powered on, so that the average power consumption of the handheld ultrasonic device can be controlled at a lower level, thereby reducing the power consumption of the handheld ultrasonic device and improving the performance of the handheld ultrasonic device.
[0083] In this embodiment, a power consumption control method is provided, which can be used for the above-mentioned handheld ultrasound device. The handheld ultrasound device includes a first control module, a second control module and a functional module. The first control module is used to communicate with the host computer and control the power-on status of the second control module and the functional module. The second control module is used to control the functional module to obtain an ultrasound image, wherein the functions of the first control module and the second control module can be integrated into one module, and are collectively referred to as a control module. Figure 4 is a flow chart of a power consumption control method according to an embodiment of the present invention. Figure 4 As shown, the process includes the following steps:
[0084] Step S401, monitor the communication status between the local computer and the host computer. Figure 3 Step S301 of the illustrated embodiment will not be described in detail here.
[0085] Step S402: If the communication state is not connected, the local is powered on and at least one of the remaining modules in the handheld ultrasound device is not powered on, the local is the control module in the handheld ultrasound device, and the remaining modules include the modules in the handheld ultrasound device other than the control module. Figure 3 Step S302 of the illustrated embodiment will not be described in detail here.
[0086] Step S403: If the communication status is connected, control the local power supply and at least one of the remaining modules to be powered on to perform ultrasonic scanning on the target object. Figure 3 Step S303 of the illustrated embodiment will not be described in detail here.
[0087] Step S404: receiving a control signal for controlling the local area.
[0088] As described above, by receiving the control signal for controlling the local part, it is ensured that the power consumption of the handheld ultrasonic device is controlled according to demand.
[0089] Step S405: if the control signal is a freeze signal, control at least one of all the remaining modules to be powered off.
[0090] The power consumption control method provided in the embodiment of the present invention controls at least one of all the remaining modules to be powered off by receiving a control signal, thereby ensuring that the power consumption of the handheld ultrasound device is controlled according to demand.
[0091] In some optional embodiments, if the control signal is a freeze signal, at least one of all the remaining modules is controlled to be powered off, and the first total power consumption of the local and all the remaining modules can be obtained; when the first total power consumption is greater than the first power consumption threshold, at least one of all the remaining modules is controlled to be powered off.
[0092] The power consumption control method provided in an embodiment of the present invention can achieve the purpose of saving power consumption by controlling the power consumption of a handheld ultrasound device by controlling at least one of all the remaining modules to be powered off when the first total power consumption of the local and all the remaining modules is greater than the first power consumption threshold.
[0093] In some optional implementations, when determining the current power consumption mode of the handheld ultrasonic device, the current power input information of the power module, the device operating environment of the handheld ultrasonic device, and the freeze-thaw signal can also be obtained first, and the freeze-thaw signal is used to indicate whether to stop the ultrasonic scanning of the handheld ultrasonic device; based on the current power input information of the power module, the device operating environment of the handheld ultrasonic device, and the freeze-thaw signal, the current power consumption mode of the handheld ultrasonic device is determined. Among them, the current power input information includes the power supply state of the power module and the duration of the power supply state; the device operating environment of the handheld ultrasonic device includes the device temperature and operating time of the handheld ultrasonic device; the freeze-thaw signal includes a freeze signal and a thaw signal, the freeze signal is used to indicate that the handheld ultrasonic device stops ultrasonic scanning, and the thaw signal is used to indicate that the handheld ultrasonic device starts ultrasonic scanning.
[0094] Specifically, when the power module is in the power supply state, the power supply amount is in the increasing state and has not reached the power threshold, it can be determined that the handheld ultrasonic device is in the power-on state. When the handheld ultrasonic device is in the power-on state, it indicates that the handheld ultrasonic device will change from the power-off state to the power-on state, thereby realizing the ultrasonic scanning of the target object. Optionally, it can also be determined according to the duration of the power module in the power supply state, that is, when the power module is in the power supply state, and the duration of the power supply state is within the time range of the first control module, the second control module and the functional module for powering on and program loading, then the handheld ultrasonic device can also be considered to be in the power-on state. Similarly, when the power supply is in the power supply state, the power supply amount is in the decreasing state and a freeze signal is received, the power consumption mode of the handheld ultrasonic device can be determined as the first power consumption mode. When the handheld ultrasonic device is in the frozen state, it indicates that the handheld ultrasonic device will end the ultrasonic scanning of the target object and enter the low power consumption state; when the power supply is in the input state, the input amount is in the increasing state and a thawing signal is received, the current device state of the handheld ultrasonic device can be determined as the thawed state. When the handheld ultrasonic device is in the thawed state, it indicates that the handheld ultrasonic device will end the low power consumption state and enter the ultrasonic scanning of the target object.
[0095] In specific implementation, when the handheld ultrasonic device is in a normal scanning and image outputting state, the first total power consumption of the first control module, the second control module and the functional module is greater than the first power consumption threshold (maximum power consumption threshold), and when the instruction (freeze signal) to freeze the handheld ultrasonic device issued by the first sub-control is received, the power-on state of each module in the functional module is adjusted so that the modules that have been powered on, such as the second control module, the transmitting module, the receiving module and the acoustic head, are powered off. At this time, only the first control module of the handheld ultrasonic device is still in the working state, and the second control module, the transmitting module, the receiving module, the acoustic head and other modules are all in the power-off state. The power consumption at this time is only the rated power consumption of the first control module; therefore, the power consumption of the handheld ultrasonic device is at an extremely low level at this time. Optionally, some modules in the transmitting module, the receiving module and the acoustic head can also be powered off.
[0096] Exemplarily, the handheld ultrasound device is in a normal scanning and image outputting state, that is, in the scanning and image outputting state, the first sub-control (freeze button) is pressed, wherein the first sub-control can be a physical button for freezing on the handheld ultrasound device, or the same button can be used for freezing and unfreezing; the first control module on the handheld ultrasound device detects a freeze signal; after the first control module detects the freeze signal, the control power module powers off the second control module, the transmitting module, the receiving module and other modules; the handheld ultrasound device enters a frozen state, at which time only the first control module of the handheld ultrasound device is still in working state, and the second control module, the transmitting module, the receiving module and other modules are all in a power-off state, and the power consumption at this time is only the rated power consumption of the first control module, so the power consumption of the handheld ultrasound device is at an extremely low level at this time, thereby effectively reducing the average power consumption of the handheld ultrasound.
[0097] Step S406: If the control signal is a thawing signal, control at least one of all the remaining modules to be powered on.
[0098] The power consumption control method provided by the embodiment of the present invention controls at least one of the remaining modules to be powered on when the control signal is a thawing signal, so as to collect ultrasonic images.
[0099] In some optional embodiments, if the control signal is a thawing signal, when at least one of all the remaining modules is controlled to be powered on, the second total power consumption of the local and powered-on modules can be obtained; when the second total power consumption is greater than the first power consumption threshold and less than the second power consumption threshold, at least one of all the remaining modules that are not powered on is controlled to be powered on, so that the second total power consumption is greater than or equal to the second power consumption threshold.
[0100] The power consumption control method provided in the embodiment of the present invention controls at least one of the remaining modules that are not powered on to be powered on based on the second total power consumption of the local and other powered-on modules when the control signal is a thawing signal, so as to collect ultrasonic images.
[0101] In specific implementation, when the handheld ultrasonic device is in a frozen state, that is, the second total power consumption of the functional modules that are not powered on in the remaining modules is greater than the first power consumption threshold and less than the second power consumption threshold, and at the same time, when an instruction (thawing signal) to thaw the handheld ultrasonic device is received, the power-on state of each module that is not powered on in the remaining modules is adjusted to power on the modules that are not powered on, such as the second control module, the transmitting module, the receiving module, and the acoustic head, and complete the power-on initialization. At this time, the handheld ultrasonic device is restored from the frozen state to the normal scanning and image output state. Optionally, some modules in the second control module, the transmitting module, the receiving module, the acoustic head, etc. can also be powered on.
[0102] Exemplarily, the user presses the second sub-control (thaw button), where the second sub-control can be a physical button for thawing on the handheld ultrasound device, or the same button can be used for thawing and freezing; the first control module on the handheld ultrasound device detects the thawing signal; after the first control module detects the thawing signal, the power supply module controls the power on the second control module, the transmitting module, the receiving module and other modules; the handheld ultrasound device is powered on and completes power-on initialization; the handheld ultrasound device returns to a normal scanning and image output state.
[0103] In some optional implementations, if the control signal is a thawing signal, the local power-on and at least one of the remaining modules are controlled to be powered on, so as to perform ultrasonic scanning on the target object, and then the operating temperature or working time of all the remaining modules can be detected; if the operating temperature or the operating time reaches the corresponding first preset value, at least one of the remaining modules that have been powered on is controlled not to be powered on, that is, standby and dormant low power consumption control is performed.
[0104] The power consumption control method provided in the embodiment of the present invention controls power consumption through operating temperature or operating time to avoid power consumption loss caused by high operating temperature or excessively long operating time. When the operating temperature or operating time of the handheld ultrasonic device reaches the corresponding first preset value, at least one of the remaining powered-on modules is controlled to be powered-off, so that the average power consumption of the handheld ultrasonic device can be controlled at a lower level, further reducing the power consumption of the handheld ultrasonic device.
[0105] During specific implementation, the handheld ultrasonic device is in a normal scanning and image outputting state; the first control module detects that the temperature of the handheld ultrasonic device exceeds the standard or the continuous working time of the handheld ultrasonic device reaches the upper limit; when the first control module detects that the temperature of the handheld ultrasonic device exceeds the standard or the continuous working time of the handheld ultrasonic device reaches the upper limit, it immediately controls the power supply module to power off the second control module, the transmitting module, the receiving module and other modules; after the second control module, the transmitting module, the receiving module and other modules are powered off, the handheld ultrasonic device enters a standby dormant state; after the handheld ultrasonic device enters the dormant state, the temperature will gradually decrease over time, and when the first control module detects that the temperature of the handheld ultrasonic device returns to a normal range or the standby dormant time of the handheld ultrasonic device reaches the standard, it controls the power supply module to power on the second control module, the transmitting module, the receiving module and other modules; the handheld ultrasonic device is powered on and completes the power-on initialization, and the handheld ultrasonic device returns to a normal scanning and image outputting state.
[0106] Among them, the purpose of the standby sleep low power consumption control is to prevent the temperature of the handheld ultrasonic device from being too high, and to quickly restore it to the normal range or to prevent the user from failing to operate the handheld ultrasound in time after the scanning is completed, and entering the frozen state, causing waste of power consumption. When the first control module detects that the temperature of the handheld ultrasonic device exceeds the standard or the continuous working time of the handheld ultrasonic device reaches the upper limit, the power supply module is controlled to power off the second control module, the transmitting module, the receiving module and other modules, so that the handheld ultrasonic device enters the standby sleep state. At this time, only the first control module is in the working state, so that the handheld ultrasonic device is in an extremely low power consumption level, and the temperature of the handheld ultrasonic device can be quickly reduced to the normal range. When the handheld ultrasonic device is stably restored to the normal range or the sleep time reaches the upper limit, the first control module controls the power supply module to power on the second control module, the transmitting module, the receiving module and other modules, and automatically exits the sleep state and enters the normal scanning state.
[0107] In some optional embodiments, if the operating temperature or the operating duration reaches a corresponding first preset value, after controlling at least one of the remaining modules that are powered on to be powered off, the current operating temperature or power-off duration of all the remaining modules can also be detected; if the current operating temperature meets a second preset value or the power-off duration reaches a preset duration, control at least one of the remaining modules to be powered on.
[0108] The power consumption control method provided in an embodiment of the present invention controls at least one of all the remaining modules to be powered on when the current operating temperature of the handheld ultrasound device meets the second preset value or the sleep time reaches the preset sleep time, so that the handheld ultrasound device can enter the normal working state of scanning and outputting images in time.
[0109] In specific implementation, after the handheld ultrasound enters the sleep state, the temperature will gradually decrease over time. When the first control module detects that the temperature of the handheld ultrasound device has returned to the normal range or the standby sleep time of the handheld ultrasound device has reached the standard, the control power module powers on the second control module, the transmitting module, the receiving module and other modules; the handheld ultrasound device is powered on and completes the power-on initialization, and the handheld ultrasound device returns to the normal scanning and image output state.
[0110] Among them, the purpose of the standby sleep low power consumption control is to prevent the temperature of the handheld ultrasonic device from being too high, and to quickly restore it to the normal range or to prevent the user from failing to operate the handheld ultrasound in time after the scanning is completed, and entering the frozen state, causing waste of power consumption. When the first control module detects that the temperature of the handheld ultrasonic device exceeds the standard or the continuous working time of the handheld ultrasonic device reaches the upper limit, the power supply module is controlled to not power on the second control module, the transmitting module, the receiving module and other modules, so that the handheld ultrasonic device enters the standby sleep state. At this time, only the first control module is in the working state, so that the handheld ultrasonic device is in an extremely low power consumption level, and the temperature of the handheld ultrasonic device can be quickly reduced to the normal range. When the handheld ultrasonic device is stably restored to the normal range or the sleep time reaches the upper limit, the first control module controls the power supply module to power on the second control module, the transmitting module, the receiving module and other modules, and automatically exits the sleep state and enters the normal scanning state.
[0111] Furthermore, in actual application scenarios, the time for a user to use a handheld ultrasonic device to perform an ultrasonic scan on each target object is generally within 5 minutes, and after the scan is completed, the user will basically switch the handheld ultrasonic device to a frozen state. It can be seen that in actual applications, the handheld ultrasonic device is idle most of the time, that is, the power consumption is extremely low. Assume that in actual applications, the time for the target object to be ultrasonically scanned accounts for 20% in total, and the handheld ultrasonic device is idle for 80%; at the same time, assume that the power consumption of the handheld ultrasonic device for normal scanning is 5 watts; and considering that the rated power consumption of the first control module is about 0.2 watts, that is, the power consumption of the handheld ultrasonic device during idle time is about 0.2 watts. It can be estimated that the average power consumption of the handheld ultrasonic device of the present invention is 5*20%+0.2*80%=1.16 watts. If you want to ensure a working time of 8 hours a day, you only need to configure a battery capacity of 1.16 watts*8 hours / 3.7V (nominal voltage of lithium battery)=2500mAh, that is, the battery capacity only needs to be greater than 2500mAh to meet the working time requirement of 8 hours a day. Relatively speaking, the prior art does not have low power consumption in idle state. If the working power consumption is always 5 watts, to meet the working time of 8 hours a day, the required battery capacity is 5 watts * 8 hours / 3.7V = 10800mAh, which is 4 times the battery capacity required by the present invention. It is hereby stated that the power-related data listed above are only for reference and comparison and analysis, and are not the basis of the present invention.
[0112] Therefore, since the average power consumption of the handheld ultrasound of the present invention can be controlled at a very low level, only a small-capacity battery is needed to ensure the 8-hour working time requirement of the device. Due to the small battery capacity, the weight and size of the device are also reduced accordingly, making it convenient for users to operate with one hand. At the same time, since there is no concern about power consumption, 64 channels or even more channels can be provided to provide the quality of ultrasound images, and the device can be turned on for a long time without damaging the device.
[0113] At the same time, since the transmitting module, receiving module, and acoustic head of the handheld ultrasonic device of the present invention are all in an unpowered state during the idle state / time (frozen state / time, standby sleep state / time, and the interval time from power-on to successful WIFI connection), the wear and tear on the components is relatively small, greatly extending the life cycle of these components. This is also another beneficial technical effect produced by the present invention in addition to solving the defects of the prior art.
[0114] The power consumption control method provided in this embodiment first powers on the first control module after the handheld ultrasonic device is started, and obtains the current power consumption mode, so as to determine the corresponding power consumption control mode based on the current power consumption mode, thereby realizing low power consumption control of the handheld ultrasonic device; when the current power consumption mode is the first power consumption mode, the second control module and at least one of the functional modules are controlled to be off, so that the average power consumption of the handheld ultrasonic device can be controlled at a low level, so that only a small-capacity battery is needed to ensure the working time of the device, which is also a prerequisite for the device to increase the number of channels and improve product performance; when the current power consumption mode is the second power consumption mode, the second control module and the functional module are controlled to be powered on to collect ultrasonic images, thereby realizing ultrasonic scanning of the target object.

[0123] In some optional embodiments, when the handheld ultrasonic device is in a frozen state, the user presses a thaw button (second functional sub-control), where the solution button can be a thaw software virtual button on the host computer interface, or a thaw entity physical button on the handheld ultrasonic device, or the same button can be used for thawing and freezing; the first control module on the handheld ultrasonic device detects a thaw signal; after the first control module detects the thaw signal, the control power module powers on the second control module, the transmitting module, the receiving module and other modules; the handheld ultrasonic device is powered on and completes power-on initialization; the handheld ultrasonic device returns to a normal scanning and image output state.
