Technical Field

The invention relates to the technical field of ultrasonic imaging, in particular to a power consumption control method, device, equipment and system of handheld ultrasonic equipment.

Background

In the related art, an ultrasonic apparatus mainly includes two parts of an ultrasonic probe and an ultrasonic mainframe. The ultrasonic probe is used for transmitting and receiving ultrasonic waves in the ultrasonic detection process. The ultrasonic host is used for processing ultrasonic data and displaying the processed ultrasonic data on a display in the form of an ultrasonic image. However, the ultrasonic equipment has the problems of large volume, high price, heavy weight, inconvenient movement and the like, and is difficult to meet the application in the moving scenes such as the outdoor, emergency ambulance and the like. Thus, hand-held ultrasound devices have evolved.

The handheld ultrasonic equipment integrates part of functions of an original ultrasonic host into an ultrasonic probe, the ultrasonic probe processes ultrasonic data, the processed ultrasonic data is uploaded to a mobile terminal, and the mobile terminal optimizes the ultrasonic data and displays corresponding ultrasonic images. Therefore, the weight and the volume of the handheld ultrasonic equipment are greatly reduced, and the handheld ultrasonic equipment can be widely applied to various mobile scenes such as outdoors, emergency ambulances and the like.

However, as the ultrasonic probe of the handheld ultrasonic device integrates a processor, a transmitting module, a receiving module and other high-power devices, the power consumption of the handheld ultrasonic device is high, and the detection performance of the device is affected.

Disclosure of Invention

In view of the above, the invention provides a method, a device and a system for controlling power consumption of a handheld ultrasonic device, so as to solve the problem that the power consumption of the handheld ultrasonic device is larger, thereby influencing the detection performance of the device.

In a first aspect, the present invention provides a method for controlling power consumption of a handheld ultrasonic device, the method comprising:

Acquiring the current working condition and the current transmitting voltage of the handheld ultrasonic equipment;

determining a target transmit voltage based on the current operating conditions;

And if the target transmitting voltage is inconsistent with the current transmitting voltage, adjusting the transmitting voltage of the handheld ultrasonic equipment to the target transmitting voltage so as to adjust the working power consumption of the handheld ultrasonic equipment.

In this manner, the transmit voltage of the handheld ultrasonic device is dynamically adjusted based on the operating conditions of the handheld ultrasonic device. Since the transmitting voltage of the handheld ultrasonic device is positively correlated with the power consumption of the transmitting power supply of the handheld ultrasonic device, the transmitting power supply is a module with larger power consumption in the handheld ultrasonic device. Therefore, the power consumption of the transmitting power supply can be reduced as much as possible based on different working conditions to dynamically adjust the transmitting voltage, so that the overall power consumption of the handheld ultrasonic equipment is reduced, and the performance of the handheld ultrasonic equipment is improved.

In an alternative embodiment, the method further comprises:

determining at least one gain parameter for adjusting the brightness of the ultrasound image based on the target emission voltage;

And adjusting the ultrasonic image data acquired by the handheld ultrasonic equipment based on the at least one gain parameter so as to adjust the brightness of the ultrasonic image.

In this manner, while adjusting the transmission voltage of the handheld ultrasonic device to the target transmission voltage, at least one gain parameter for adjusting the brightness of the ultrasonic image is determined based on the target transmission voltage to adjust the ultrasonic image data acquired by the handheld ultrasonic device, thereby adjusting the brightness of the ultrasonic image. Therefore, the problem of abrupt image brightness change caused by the change of the emission voltage can be avoided.

In an alternative embodiment, the transmitting voltage of the hand-held ultrasonic device is divided into a plurality of voltage levels, and the determining at least one gain parameter for adjusting the brightness of the ultrasonic image based on the target transmitting voltage comprises:

Obtaining a target gain compensation factor corresponding to the target emission voltage, wherein the target gain compensation factor is obtained based on a target voltage grade corresponding to the target emission voltage and the corresponding relation between each voltage grade and the gain compensation factor;

the at least one gain parameter is determined based on the target gain compensation factor, the target gain compensation factor corresponding to the at least one gain parameter.

In this manner, a target gain compensation factor corresponding to the target emission voltage is obtained, the target gain compensation factor being based on a target voltage class corresponding to the target emission voltage, and a correspondence between each voltage class and the gain compensation factor. At least one gain parameter is then determined based on the target gain compensation factor. Therefore, frequent adjustment of the gain parameter along with the change of the voltage can be avoided, and the problem of abrupt change of the brightness of the ultrasonic image is further avoided. At the same time, different gain parameter combinations are characterized by one gain compensation factor. Therefore, if the upper computer regulates and controls the handheld ultrasonic equipment, the upper computer only needs to send a target gain compensation factor to the handheld ultrasonic equipment, and the handheld ultrasonic equipment can determine at least one gain parameter according to the target gain compensation factor. Therefore, the data volume to be transmitted between the upper computer and the handheld ultrasonic device can be reduced, so that the probability of data transmission errors is reduced.

In an alternative embodiment, if the current operating condition includes an image depth, the determining the target emission voltage based on the current operating condition includes:

the target emission voltage is determined based on the image depth, the target emission voltage being positively correlated with the image depth.

In this manner, if the image depth is included in the current operating conditions, a target emission voltage is determined based on the image depth, the target emission voltage being positively correlated with the image depth. Therefore, the transmission voltage of the handheld ultrasonic device can be appropriately reduced when the image depth is small, so as to reduce the power consumption of the handheld ultrasonic device.

In an alternative embodiment, if the current operating condition includes an operating temperature of the handheld ultrasonic device, the determining the target emission voltage based on the current operating condition further includes:

And if the operating temperature is greater than a preset temperature threshold, determining the target emission voltage based on the operating temperature, wherein the target emission voltage is inversely related to the operating temperature.

In this manner, if the current operating condition includes an operating temperature of the handheld ultrasonic device, then, if the operating temperature is greater than a preset temperature threshold, a target emission voltage is determined based on the operating temperature, the target emission voltage being inversely related to the operating temperature. Therefore, when the operation temperature of the handheld ultrasonic equipment is too high, the power consumption can be reduced by reducing the emission voltage, so that the operation temperature of the handheld ultrasonic equipment is reduced, and the damage to the handheld ultrasonic equipment is avoided.

In an alternative embodiment, if the current operating condition includes an expected continuous operating time period of the handheld ultrasonic device, the determining the target transmitting voltage based on the current operating condition further includes:

And determining the target emission voltage based on the expected continuous working time, wherein the target emission voltage is inversely related to the expected continuous working time.

In this manner, if the current operating condition includes an expected continuous operating time period of the handheld ultrasonic device, a target transmit voltage is determined based on the preset continuous operating time period, where the target transmit voltage is inversely related to the expected continuous operating time period. Therefore, when the handheld ultrasonic device is in a scene requiring long-time continuous operation, the power consumption is reduced by reducing the emission voltage, and the endurance time of the handheld ultrasonic device is improved, so that the long-time continuous operation of the handheld ultrasonic device is ensured, and the ultrasonic detection efficiency is improved.

In an alternative embodiment, if the current operating condition includes an operation mode of the handheld ultrasonic device, the determining the target emission voltage based on the current operating condition further includes:

If the operation mode is a sleep mode, determining that the target emission voltage is a preset minimum voltage;

And if the operation mode is a working mode, acquiring a current ultrasonic mode, and determining the target transmitting voltage based on the current ultrasonic mode.

In this manner, if the current operating condition includes an operation mode of the handheld ultrasonic device, the target emission voltage is determined to be a preset minimum voltage in the case that the operation mode is a sleep mode. Therefore, the power consumption of the handheld ultrasonic device in the sleep state can be reduced. And determining a target emission voltage based on the current ultrasound mode if the operational mode is an operational mode. Therefore, the transmitting voltage of the handheld ultrasonic device can be adjusted according to different ultrasonic modes without sacrificing the image quality as much as possible so as to reduce the power consumption.

In a second aspect, the present invention provides a power consumption control apparatus for a handheld ultrasonic device, the apparatus comprising:

the data acquisition module is used for acquiring the current working condition and the current transmitting voltage of the handheld ultrasonic equipment;

a voltage determination module for determining a target transmit voltage based on the current operating condition;

and the power consumption control module is used for adjusting the transmitting voltage of the handheld ultrasonic equipment to the target transmitting voltage if the target transmitting voltage is inconsistent with the current transmitting voltage so as to adjust the working power consumption of the handheld ultrasonic equipment.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The terms first and second in the description and claims of the invention and in the above-mentioned figures are used for distinguishing between different objects and not for describing a particular sequential order. Furthermore, the term "include" and any variations thereof is intended to cover non-exclusive protection. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus. The term "plurality" in the present invention may mean at least two, for example, two, three or more, and embodiments of the present invention are not limited.

At present, the traditional ultrasonic equipment has the problems of large volume, high price, large weight, inconvenient movement and the like, and is difficult to meet the application in the moving scenes such as the outdoor, emergency ambulance and the like. Thus, hand-held ultrasound devices have evolved.

The handheld ultrasonic equipment integrates part of functions of a traditional ultrasonic host into an ultrasonic probe, the ultrasonic probe processes ultrasonic data, the processed ultrasonic data is uploaded to mobile terminals such as a mobile phone and a tablet personal computer, the mobile terminal optimizes the ultrasonic data and displays corresponding ultrasonic images on a screen of the mobile terminal. Therefore, the weight and the volume of the handheld ultrasonic equipment are greatly reduced, the handheld ultrasonic equipment is convenient to carry, and the handheld ultrasonic equipment can be widely applied to various mobile scenes such as outdoors, emergency ambulances and the like.

Fig. 1 shows a block diagram of a hand-held ultrasound device. As shown in fig. 1, the handheld ultrasonic device comprises a sound head 101, a transmitting module 102, a receiving module 103, a communication module 104, a transmitting power supply 105, a main controller 106 and a single chip microcomputer 107.

The sound head 101 is used for converting an electrical signal into an acoustic signal and converting a reflected acoustic signal into an electrical signal to form an echo signal. The sound head 101 can be in different types of linear array, convex array, phased array and the like, and the basic working principle of the sound head is basically the same.

The transmitting module 102 is used for generating transmitting waveforms with different frequencies and generating high-voltage transmitting pulses with specific frequencies under the control of the main controller 106. The handheld ultrasonic device may include one transmitting module 102, or may include a plurality of transmitting modules 102.

The receiving module 103 is configured to receive the echo signal output by the sound head 101, and send the echo signal to the main controller 106, so that the main controller 106 processes the received echo signal, and generates corresponding ultrasound image data. The handheld ultrasonic probe may include one receiving module 103, or may include a plurality of receiving modules 103.

The communication module 104 is configured to transmit the ultrasound image data generated by the main controller 106 to an upper computer (e.g., a mobile phone, a tablet computer, etc.), or is configured to receive an instruction issued by the upper computer. The communication module 104 may be a wireless communication module, such as a WIFI antenna.

The emission power source 105 is used for generating high voltage emission power sources of different emission voltages, for example, high voltage emission power sources within 100V.

The main controller 106 includes one or more control units, and the main controller 106 is used for transmission/reception delay control, beam forming, processing in different ultrasound modes (e.g., B/C/D mode), and the like. Specifically, when ultrasound imaging is desired, the main controller 106 may transmit ultrasound signals by controlling the transmit power supply 105 and the transmit module 102.

The single-chip microcomputer 107 comprises a single-chip microcomputer chip and a matched power supply. The single chip microcomputer 107 is used for packaging ultrasonic data and communicating with the upper computer based on the communication module 104, so that the ultrasonic image data is uploaded to the upper computer. And the communication module 104 is used for receiving a control instruction issued by the upper computer, so as to realize the control of the handheld ultrasonic equipment, such as the control of powering on and powering off the handheld ultrasonic equipment.

Because the ultrasonic probe of the handheld ultrasonic device integrates a processor (i.e. the main controller 106 and the singlechip 107), the transmitting module 102, the receiving module 103 and other high-power devices, the power consumption of the handheld ultrasonic device is larger, and the detection performance of the device is affected. For example, the heat productivity of the handheld ultrasonic probe is large due to the large power consumption of the handheld ultrasonic device. Meanwhile, due to size limitation, the handheld ultrasonic equipment cannot integrate the radiating equipment such as the radiating fan, the radiating fin and the like to radiate heat for the handheld ultrasonic equipment, so that the handheld ultrasonic equipment radiates heat slowly, and the contradiction that the probe of the handheld ultrasonic equipment generates large heat and radiates heat slowly is outstanding.

Therefore, in the related art, the handheld ultrasonic device mainly solves the problem of high power consumption by firstly reducing the number of channels of the handheld ultrasonic device so as to reduce the performance of the handheld ultrasonic device and avoid generating excessive heat. However, the too small number of channels can result in poor quality of the displayed ultrasound image, and it is difficult to meet the clinical requirements of medium-high-end image quality. Secondly, the continuous working time of the handheld ultrasonic equipment is limited, and the ultrasonic probe is prevented from being overheated. However, limiting the working time of the handheld ultrasonic device can result in a shorter continuous working time of the handheld ultrasonic device, and the continuous working time (e.g., 10 minutes) of the handheld ultrasonic device can force the handheld ultrasonic device to stop working, thereby affecting the clinical detection efficiency. Thirdly, the battery capacity of the handheld ultrasonic equipment is increased to ensure the working time of the ultrasonic probe, meanwhile, the volume of the handheld ultrasonic equipment is required to be increased so as to facilitate heat dissipation, and the weight of the handheld ultrasonic equipment is also increased, so that the handheld ultrasonic equipment is inconvenient to operate by one hand.

In other words, portable hand-held ultrasound devices are mainly used in the field of ambulatory medical treatment, and thus have strict limitations on their size and weight. Therefore, it is difficult for the handheld ultrasonic device to radiate heat by adding a heat radiating device such as a fan or a heat radiating fin like the large ultrasonic device. If the number of channels is reduced to reduce the heat of the handheld ultrasonic device, it means that the number of transmitting and receiving chips at the front end of the handheld ultrasonic device needs to be reduced, and the time for processing the ultrasonic data needs to be reduced, although the power consumption is reduced, the quality of the ultrasonic image is poor, and it is difficult to meet the clinical requirements of middle and high ends. In addition, if the number of channels is reduced, the heat balance still is difficult to reach, and the continuous working time of the handheld ultrasonic device is required to be correspondingly limited, otherwise, abnormal working, image errors and the like of the device and even damage of the device can still be caused due to overheating. Moreover, if the average power consumption of the handheld ultrasonic device in unit time cannot be effectively reduced, a battery with larger capacity needs to be provided to ensure the working time of the device, so that the volume and the weight of the handheld ultrasonic device are correspondingly increased, and the handheld ultrasonic device is inconvenient for a user to operate by one hand.

It can be seen that the above-mentioned handheld ultrasonic device has the problems of small number of channels, long and short continuous operation time, large volume and large weight, and the essence of these problems is caused by the excessive average power consumption of the handheld ultrasonic device. Therefore, reducing power consumption of the handheld ultrasonic device is a highly desirable problem.

In view of the foregoing, there is provided in accordance with an embodiment of the invention a method for controlling power consumption of a handheld ultrasonic device, it being noted that the steps illustrated in the flowchart of the figures may be performed in a computer system, such as a set of computer executable instructions, and that, although a logical sequence is illustrated in the flowchart, in some cases, the steps illustrated or described may be performed in a different order than that illustrated herein.

The embodiment provides a power consumption control method of a handheld ultrasonic device, which can be used for the control module of the handheld ultrasonic device or an upper computer in communication connection with the handheld ultrasonic device, such as a mobile terminal of a mobile phone, a tablet computer and the like. The control module comprises a main controller 106 and a singlechip 107, and is used for controlling the rest modules of the handheld ultrasonic device, such as the sound head 101, the transmitting module 102, the receiving module 103, the communication module 104, the transmitting power supply 105 and the like. Fig. 2 is a schematic flow chart of a power consumption control method of a handheld ultrasonic device according to an embodiment of the present invention, as shown in fig. 2, the flow chart includes the following steps:

Step S11, the current working condition and the current transmitting voltage of the handheld ultrasonic device are obtained.

Specifically, the current operating conditions include at least one of image depth, operating temperature, expected continuous operating duration, and operating mode. Wherein the operational mode includes a sleep mode including at least one of a freeze mode and a standby mode and the operational mode includes a plurality of ultrasonic modes, such as a B/C/D mode.

Specifically, as shown in fig. 3, the handheld ultrasonic device further includes an analog-to-digital conversion chip 108. The control module collects the current transmit voltage of the transmit power supply 105 through the analog-to-digital conversion chip 108.

Step S12, determining a target emission voltage based on the current operating conditions.

Specifically, different emission voltages may be configured in advance for different working conditions, so as to obtain correspondence between the multiple working conditions and the emission voltages. For example, operating condition 1 corresponds to emission voltage 1, operating condition 2 corresponds to emission voltage 2, operating condition 3 corresponds to emission voltage 3, and so on.

In the operation process of the handheld ultrasonic device, a target transmitting voltage is determined based on the current working condition and the corresponding relation between the plurality of working conditions and the transmitting voltage. For example, the current operating condition is operating condition 1, and the target emission voltage is emission voltage 1.

Specifically, in the actual operation process, the upper computer may determine the target transmitting voltage according to the current working condition, and send the target transmitting voltage to the control module (such as the single-chip microcomputer 107) of the handheld ultrasonic device through the communication module 104 (such as WIFI).

Step S13, if the target transmitting voltage is inconsistent with the current transmitting voltage, the transmitting voltage of the handheld ultrasonic equipment is adjusted to the target transmitting voltage so as to adjust the working power consumption of the handheld ultrasonic equipment.

Specifically, as shown in fig. 3, the handheld ultrasonic device further includes a digital-to-analog conversion chip 109. When the control module (such as the singlechip 107) receives the target transmitting voltage issued by the upper computer, if the target transmitting voltage is inconsistent with the current transmitting voltage, the control module issues the target transmitting voltage to the transmitting power supply 105 through the digital-to-analog conversion chip 109, so that the transmitting power supply 105 automatically adjusts the output transmitting voltage based on the received target transmitting voltage. At this time, the control module periodically collects the voltage adjustment result of the emission power supply 105 through the analog-to-digital conversion chip 108, so as to control the emission power supply 105 to regulate and control the output emission voltage according to the voltage adjustment result, until the emission voltage output by the emission power supply 105 reaches the target emission voltage. For example, if the voltage adjustment result is greater than the target emission voltage, the control module controls the emission power source 105 to decrease the output emission voltage. If the voltage adjustment result is less than the target transmit voltage, the control module controls the transmit power supply 105 to increase the output transmit voltage. To avoid a large error between the emission voltage output from the emission power source 105 and the target emission voltage.

It should be noted that, if the target transmission voltage is consistent with the current transmission voltage, the transmission voltage of the handheld ultrasonic device is not adjusted.

According to the power consumption control method of the handheld ultrasonic device, the transmitting voltage of the handheld ultrasonic device is dynamically adjusted based on the working condition of the handheld ultrasonic device. Since the transmit voltage of the handheld ultrasonic device is positively correlated with the power consumption of the transmit power supply 105 of the handheld ultrasonic device, the transmit power supply 105 is a module of the handheld ultrasonic device that consumes more power. Therefore, by dynamically adjusting the transmitting voltage based on different working conditions, the power consumption of the transmitting power supply 105 can be reduced as much as possible, so as to reduce the overall power consumption of the handheld ultrasonic device, and improve the performance of the handheld ultrasonic device.

For example, in order to ensure that the brightness of an ultrasonic image does not have abrupt changes of brightness and darkness under different working conditions, a conventional ultrasonic device often has a fixed emission voltage, so that the process of debugging the ultrasonic device is simplified, and the development period of the ultrasonic device is shortened. However, conventional ultrasonic devices are typically powered by an external power source, which is insensitive to power consumption, and a fixed transmit voltage has no significant effect on the conventional ultrasonic device. However, for the handheld ultrasonic device, the volume and weight of the handheld ultrasonic device need to be limited, and the battery capacity is limited, which results in that the handheld ultrasonic device is sensitive to power consumption, and thus, the power consumption of the handheld ultrasonic device needs to be finely controlled.

Taking the example of 60V as the transmitting voltage of the transmitting power source 105 of the handheld ultrasonic device, at this time, the power consumption of each module of the handheld ultrasonic device is measured through experiments, as shown in fig. 4, the power consumption of the transmitting module 102 accounts for 7% of the power consumption of the whole machine, the power consumption of the transmitting power source 105 accounts for 36% of the power consumption of the whole machine, the main controller 106 accounts for 23% of the power consumption of the whole machine, the power consumption of the receiving module 103 accounts for 21% of the power consumption of the whole machine, and the power consumption of the single chip microcomputer 107 accounts for 13% of the power consumption of the whole machine. It can be seen that the transmit power supply 105 is the module with the greatest power consumption in the handheld ultrasound system when the transmit voltage is 60V.

When the emission voltage of the emission power supply 105 of the handheld ultrasonic device is adjusted to 30V, the power consumption of each module of the handheld ultrasonic device is measured through experiments, as shown in fig. 5, under the condition that the power consumption of other modules is not changed, the power consumption of the emission module 102 accounts for 9% of the power consumption of the whole machine, the power consumption of the emission power supply 105 accounts for 22% of the power consumption of the whole machine, the main controller 106 accounts for 28% of the power consumption of the whole machine, the power consumption of the receiving module 103 accounts for 26% of the power consumption of the whole machine, and the power consumption of the single chip microcomputer 107 accounts for 15% of the power consumption of the whole machine. It can be seen that only the emission voltage of the emission power source 105 is reduced from 60V to 30V, and the power consumption of the emission power source 105 is reduced from 36% to 22% in the whole machine. Therefore, the reduction of the emission voltage can effectively reduce the overall power consumption of the handheld ultrasonic device.

In some alternative embodiments, if the current operating condition includes an image depth, determining the target emission voltage based on the current operating condition includes determining the target emission voltage based on the image depth, the target emission voltage being positively correlated with the image depth.

According to the power consumption control method of the handheld ultrasonic device, if the current working condition comprises the image depth, the target transmitting voltage is determined based on the image depth, and the target transmitting voltage is positively correlated with the image depth. Therefore, the transmission voltage of the handheld ultrasonic device can be appropriately reduced when the image depth is small, so as to reduce the power consumption of the handheld ultrasonic device.

It is worth noting that the higher the emission voltage, the deeper the image depth can be detected, i.e. the better the ultrasound penetration. When the image depth is small, the image depth requirement can be met without the need for excessive penetration force, i.e., with a low emission voltage. Therefore, when the image depth is smaller, the transmitting voltage can be properly reduced on the premise of not influencing the quality of the ultrasonic image, thereby achieving the purpose of reducing the power consumption of the handheld ultrasonic equipment.

Illustratively, assuming an image depth of 16cm, the corresponding emission voltage is 60V. Then, at an image depth of 8cm, the emission voltage can be reduced, e.g., 50V, without affecting the ultrasound image quality.

In some alternative embodiments, if the current operating condition includes an operating temperature of the handheld ultrasonic device, determining the target transmit voltage based on the current operating condition further includes determining the target transmit voltage based on the operating temperature if the operating temperature is greater than a preset temperature threshold, the target transmit voltage being inversely related to the operating temperature.

In the power consumption control method for the handheld ultrasonic device provided by the embodiment, if the current working condition includes the operation temperature of the handheld ultrasonic device, if the operation temperature is greater than the preset temperature threshold, determining a target emission voltage based on the operation temperature, wherein the target emission voltage is inversely related to the operation temperature. Therefore, when the operation temperature of the handheld ultrasonic equipment is too high, the power consumption can be reduced by reducing the emission voltage, so that the operation temperature of the handheld ultrasonic equipment is reduced, and the damage to the handheld ultrasonic equipment is avoided.

It should be noted that the preset temperature threshold may be determined according to an influence of an operation temperature of the handheld ultrasonic device on an operation performance of the handheld ultrasonic device. It should be noted that the operation temperature of the handheld ultrasonic device is the built-in temperature of the handheld ultrasonic device.

In some alternative embodiments, if the current operating condition includes an expected duration of continuous operation of the handheld ultrasonic device, determining the target transmit voltage based on the current operating condition further includes determining the target transmit voltage based on the expected duration of continuous operation, the target transmit voltage being inversely related to the expected duration of continuous operation.

According to the power consumption control method for the handheld ultrasonic device, if the current working condition comprises the expected continuous working time length of the handheld ultrasonic device, the target transmitting voltage is determined based on the preset continuous working time length, and the target transmitting voltage is inversely related to the expected continuous working time length. Therefore, when the handheld ultrasonic equipment is in a scene requiring long-time continuous operation, the power consumption is reduced by reducing the transmitting voltage, the duration of the handheld ultrasonic equipment is improved to ensure the continuous long-time operation of the handheld ultrasonic equipment, and the ultrasonic detection efficiency is improved.

It should be noted that, the expected continuous working time length can be obtained through an instruction issued by the upper computer or determined based on the current ultrasonic mode of the handheld ultrasonic device.

In some alternative embodiments, if the current working condition includes an operation mode of the handheld ultrasonic device, determining the target emission voltage based on the current working condition, and further includes determining that the target emission voltage is a preset minimum voltage if the operation mode is a sleep mode, and if the operation mode is an operation mode, acquiring the current ultrasonic mode, and determining the target emission voltage based on the current ultrasonic mode.

In the power consumption control method of the handheld ultrasonic device provided by the embodiment, if the current working condition includes the operation mode of the handheld ultrasonic device, under the condition that the operation mode is the sleep mode, the target transmitting voltage is determined to be the preset minimum voltage. Therefore, the power consumption of the handheld ultrasonic device in the sleep state can be reduced. And determining a target emission voltage based on the current ultrasound mode if the operational mode is an operational mode. Therefore, the transmitting voltage of the handheld ultrasonic device can be adjusted according to different ultrasonic modes without sacrificing the image quality as much as possible so as to reduce the power consumption.

Note that the sleep mode includes at least one of a freeze mode and a standby mode. Optionally, the preset minimum voltage is 0V. If the handheld ultrasonic device enters the freezing mode or the standby mode, the transmitting voltage can be reduced to the preset minimum voltage so that the transmitting power supply 105 is in the dormant low-power consumption mode, and therefore the power consumption of the handheld ultrasonic device in the freezing mode and the standby mode is reduced.

In addition, if the modes such as B/C/D (i.e. ultrasonic modes) are changed, the transmission waveforms of the B/C/D modes are different, so that the transmission voltage can be adjusted according to different ultrasonic modes without sacrificing the image quality, thereby reducing the power consumption.

In this embodiment, a power consumption control method is provided, which may be used in the control module of the above-mentioned handheld ultrasonic device or an upper computer, such as a mobile terminal of a mobile phone, a tablet computer, etc., which is in communication connection with the handheld ultrasonic device. The control module comprises a main controller 106 and a singlechip 107, and is used for controlling the rest modules of the handheld ultrasonic device, such as the sound head 101, the transmitting module 102, the receiving module 103, the communication module 104, the transmitting power supply 105 and the like. Fig. 6 is a flowchart of another power consumption control method of a handheld ultrasonic device according to an embodiment of the present invention, as shown in fig. 6, the flowchart including the steps of:

Step S21, the current working condition and the current transmitting voltage of the handheld ultrasonic device are obtained. Please refer to the above step S11 in detail, and the detailed description is omitted herein.

Step S23, if the target transmitting voltage is inconsistent with the current transmitting voltage, the transmitting voltage of the handheld ultrasonic device is adjusted to the target transmitting voltage so as to adjust the working power consumption of the handheld ultrasonic device. Please refer to the above step S13 in detail, which is not described herein.

Step S24, determining at least one gain parameter for adjusting the brightness of the ultrasound image based on the target emission voltage.

Specifically, gain parameters applicable to different emission voltages can be determined through experiments in advance, so that corresponding relations between a plurality of emission voltages and the gain parameters can be obtained. During operation of the handheld ultrasonic device, at least one gain parameter is determined based on the target transmit voltage and a correspondence of the plurality of transmit voltages to the gain parameter.

Specifically, the at least one gain parameter includes at least one of a low noise amplifier gain, an attenuator gain, a programmable amplifier gain, and an image post-processing gain compensation in the receiving module 103. In addition, other gain parameters for adjusting the brightness of the ultrasound image may be included.

And step S25, adjusting the ultrasonic image data acquired by the handheld ultrasonic device based on at least one gain parameter to adjust the brightness of the ultrasonic image.

Illustratively, assuming that the low noise amplifier gain b1, the attenuator gain b2, the programmable amplifier gain b3, and the image post-processing gain compensation b4 are obtained through step S24, the low noise amplifier gain, the attenuator gain, the programmable amplifier gain, and the image post-processing gain compensation in the receiving module 103 may be adjusted to b1, b2, b3, and b4, respectively, to adjust the ultrasound image data acquired by the handheld ultrasound device, thereby adjusting the ultrasound image brightness.

According to the power consumption control method for the handheld ultrasonic device, the emission voltage of the handheld ultrasonic device is adjusted to be the target emission voltage, and at least one gain parameter for adjusting the brightness of an ultrasonic image is determined based on the target emission voltage at the same time, so that the ultrasonic image data acquired by the handheld ultrasonic device are adjusted, and the brightness of the ultrasonic image is adjusted. Therefore, the problem of abrupt image brightness change caused by the change of the emission voltage can be avoided.

In some alternative embodiments, the transmit voltage of the handheld ultrasonic device is divided into a plurality of voltage levels. The step 24 includes obtaining a target gain compensation factor corresponding to the target transmit voltage, the target gain compensation factor being based on a target voltage level corresponding to the target transmit voltage and a correspondence between each voltage level and the gain compensation factor, and determining at least one gain parameter based on the target gain compensation factor, the target gain compensation factor corresponding to the at least one gain parameter.

According to the power consumption control method of the handheld ultrasonic device, the target gain compensation factors corresponding to the target transmitting voltages are obtained, and the target gain compensation factors are obtained based on the target voltage levels corresponding to the target transmitting voltages and the corresponding relations between the voltage levels and the gain compensation factors. At least one gain parameter is then determined based on the target gain compensation factor. Therefore, frequent adjustment of the gain parameter along with the change of the voltage can be avoided, and the problem of abrupt change of the brightness of the ultrasonic image is further avoided. At the same time, different gain parameter combinations are characterized by one gain compensation factor. Therefore, if the upper computer regulates and controls the handheld ultrasonic equipment, the upper computer only needs to send a target gain compensation factor to the handheld ultrasonic equipment, and the handheld ultrasonic equipment can determine at least one gain parameter according to the target gain compensation factor. Therefore, the data volume to be transmitted between the upper computer and the handheld ultrasonic device can be reduced, so that the probability of data transmission errors is reduced.

As an example, to solve the problem of abrupt image brightness change caused by the change of the transmission voltage, the transmission voltage of the handheld ultrasonic device may be divided into a plurality of voltage levels of a limited number of levels, for example, voltage level 1, voltage level 2, voltage level n, n being constant. At least one gain parameter, such as different low noise amplifier gains, attenuator gains, programmable amplifier gains, and image post-processing gain compensation in the receiving module 103, is correspondingly adjusted based on different voltage levels, so that the brightness of the ultrasonic image is ensured not to be suddenly changed under the condition of switching the voltage levels. Specifically, at least one gain parameter corresponding to each voltage level, such as a low noise amplifier gain, an attenuator gain, a programmable amplifier gain, and an image post-processing gain compensation, can be determined through experiments, so that when the voltage level is adjusted, the brightness of the ultrasonic image is adjusted through the at least one gain parameter corresponding to the adjusted voltage level, and the brightness of the ultrasonic image is not greatly suddenly changed. And then saving the experimental data to obtain the corresponding relation between each voltage level and the gain parameter.

In addition, it is considered that if data transmission is directly performed on a plurality of gain parameters between different devices, a problem of data transmission errors may occur. And in the subsequent development process, the problem of artificial uncontrollable misoperation may occur when a plurality of gain parameters are adjusted, for example, the problem of abrupt change of brightness of an ultrasonic image may be caused by only adjusting one gain parameter. The power consumption control method of the invention further combines different gain parameters to correspondingly unify a gain compensation factor through a preset relational expression. When the upper computer controls the handheld ultrasonic equipment, the control module can determine at least one gain parameter corresponding to the target gain compensation factor according to the corresponding relation between the received target gain compensation factor and a plurality of gain compensation factors stored in advance so as to reduce the probability of data transmission errors only by transmitting the target gain compensation factor corresponding to the target voltage level to the control module (such as the singlechip 107) of the handheld ultrasonic equipment. Meanwhile, each gain parameter corresponding to the target voltage level can be adjusted in a linkage mode, so that the problem of abrupt change of the brightness of the ultrasonic image is further avoided.

It can be understood that after the corresponding relation between each voltage level and the gain parameter is obtained through experiments, a plurality of gain parameters corresponding to each voltage level can be used as a gain parameter combination, and different gain parameters are combined into one gain compensation factor through a preset relation, so as to obtain the corresponding relation between the gain compensation factors and the gain parameters. And storing the corresponding relation between the gain compensation factors and the gain parameters into the handheld ultrasonic equipment and the upper computer, so that each gain parameter corresponding to the target voltage level is determined according to the target gain compensation factors corresponding to the target voltage level and the corresponding relation, and the gain parameters are adjusted in a linkage way, so that the abrupt change of the brightness of the ultrasonic image is avoided.

Specifically, taking at least one gain parameter including a low noise amplifier gain, an attenuator gain, a programmable amplifier gain, and an image post-processing gain compensation as an example, different low noise amplifier gains, attenuator gains, programmable amplifier gains, and image post-processing gain compensation can be fused by the following formulas to obtain corresponding gain compensation factors:

G_v＝A*G_LNA+B*G_ATTEN+C*G_PGA+D*G_comp;

Wherein G _v is a gain compensation factor, G _LNA is a low noise amplifier gain, G _ATTEN is an attenuator gain, G _PGA is a programmable amplifier gain, G _comp is an image post-processing gain compensation, a is a first weight corresponding to the low noise amplifier gain, B is a second weight corresponding to the attenuator gain, C is a third weight corresponding to the programmable amplifier gain, and D is a third weight corresponding to the image post-processing gain compensation.

It should be noted that the first weight, the second weight, the third weight, and the fourth weight are initialization constants.
