For example, the signal processing unit 13 may convert the received analog signal into a digital signal, may perform noise reduction processing on the received air pressure data, may also perform amplification processing on the received air pressure data, and the like.
Based on a similar procedure as described above for obtaining blood pressure data, the processor 7 may perform gas composition measurements via the gas sensor 5, for example, one way may be that the gas sensor 5 may send the collected gas data to the processor 7, the processor 7 calculates the received gas data to obtain gas composition data, the wearable device has a display through which the user views the gas composition data. For another example, the gas sensor 5 may send the collected gas data to the processor 7, and after receiving the gas data and performing some processing, the processor 7 may send the processed gas data to a processing device connected to the wearable device, so that the processing device calculates the gas data to obtain gas composition data, and the user views the gas composition data through the processing device. For another example, the gas sensor 5 may send the collected gas data to the processor 7, after the processor 7 receives the gas data and performs some processing on the gas data, the processor may send the processed gas data to a server, the server calculates the gas data to obtain gas composition data, and sends the gas composition data to a terminal associated with the wearable device, and the user may view the gas composition data through an application installed on the terminal. Wherein, the gas component data comprises gas components and the content of each gas component.
The present embodiment does not limit the specific manner of calculating the gas composition data from the gas data, and the following description may be given in the first manner in describing the measurement of the gas composition.
As described above, the processor 7 can perform blood pressure measurement by the barometer 4 and gas component measurement by the gas sensor 5. For example, the processor 7 may perform blood pressure measurements by controlling the opening and closing of the intake valve 9 and the bladder valve 10, as well as controlling the start and stop of the micro-pump 6; the gas composition measurement can be performed by controlling the opening and closing of the intake valve 9 and the bag valve 10, controlling the start and stop of the micro pump 6, and controlling the start and stop of the gas sensor 5.
As an example, in performing a blood pressure measurement, when the processor 7 detects a signal to initiate a blood pressure measurement, the air inlet valve 9 and the air bladder valve 10 are controlled to open, e.g., the air inlet valve 9 is controlled to open by the air inlet valve control 91 and the air bladder valve 10 is controlled to open by the air bladder valve control 100. Then, the processor 7 may control the micro pump 6 to start, for example, the processor 7 may control the micro pump 6 to start through the micro pump control element 61, and control the power chip 14 to provide a voltage of a certain gear to the micro pump 6, so that the processor 7 may receive the air pressure data collected by the barometer 4, and then the processor 7 may calculate the blood pressure data according to the air pressure data. When the processor 7 detects a signal to end the blood pressure measurement, the micro pump 6 is controlled to stop, for example, the processor 7 may control the micro pump 6 to stop by the micro pump control 61. After the micro-pump 6 stops working, the gas in the air bag 3 and the air chamber 2 can be freely diffused and exhausted through the vent 101, and then the processor 7 can control the air inlet valve 9 and the air bag valve 10 to be closed again, for example, the processor 7 controls the air inlet valve 9 to be closed through the air inlet valve control member 91 and controls the air bag valve 10 to be closed through the air bag valve control member 100.
Wherein, the air in the air bag 3 and the air chamber 2 is freely diffused and exhausted through the vent 101, the processor 7 can determine the time for controlling the closing of the air inlet valve 9 and the air bag valve 10 through the time length, for example, the processor 7 starts to time from the stop moment of the micro pump 6, and sends a closing instruction to the air inlet valve control member 91 and the air bag valve control member 100 when reaching a first time length, wherein the first time length can be a time length calculated by a technician through factors such as the volume of the air bag 3, the volume of the air chamber 2, the free diffusion speed of the air and the like, or a time length obtained by the technician through simulation software. Alternatively, the processor 7 may control the closing time of the intake valve 9 and the airbag valve 10 according to the received command, for example, the wearable device has a valve closing button, and after the user performs a valve closing operation, the processor 7 may receive a closing command of the intake valve 9 and the airbag valve 10, and further send a closing command to the intake valve control member 91 and the airbag valve control member 100.
As an example, in performing a gas composition measurement, when the processor 7 detects a signal to initiate a gas composition measurement, the inlet valve 9 and the airbag valve 10 are controlled to open, e.g., the inlet valve 9 is controlled to open by inlet valve control 91 and the airbag valve 10 is controlled to open by airbag valve control 100. The processor 7 may then control the micro pump 6 to start, for example, the processor 7 may control the micro pump 6 to start through the micro pump control 61 and control the power chip 14 to provide a certain gear voltage to the micro pump 6. When all the residual gas in the gas chamber 2 enters the gas bag 3 and the gas chamber 2 is filled with the gas to be measured, the processor 7 can control the micro pump 6 to stop working, for example, the micro pump 6 is controlled to stop working by the micro pump control part 61. Processor 7 then controls intake valve 9 and bladder valve 10 to close, e.g., by controlling intake valve 9 to close via intake valve control 91 and bladder valve 10 to close via bladder valve control 100. After that, the processor 7 may control the gas sensor 5 to start operation, for example, by controlling the gas sensor control 51 to control the gas sensor 5 to start operation. The processor 7 may thus receive the gas data collected by the gas sensor 5 and calculate the gas composition from the gas data. When a signal to end the gas component measurement is detected, the gas sensor 5 is controlled to stop operating, for example, the gas sensor 5 is controlled to stop operating by the gas sensor control member 51. The intake valve 9 and the airbag valve 10 are controlled to open, for example, the intake valve 9 is controlled to open by the intake valve control 91 and the airbag valve 10 is controlled to open by the airbag valve control 100. After the gas in the airbag 3 is freely diffused and exhausted through the vent 101, the air inlet valve 9 and the airbag valve 10 are controlled to be closed, for example, the air inlet valve 9 and the airbag valve 10 may be triggered to be closed by the first time period described above, or the air inlet valve 9 and the airbag valve 10 may be triggered to be closed by the valve closing operation of the user.
The processor 7 can judge that residual gas in the air cavity 2 enters the air bag 3 through time length, and the air cavity 2 is filled with gas to be detected, for example, the processor 7 starts timing at the working moment of the self-starting micropump 6, and when the time length reaching the second time length is detected, the residual gas in the air cavity 2 can be determined to enter the air bag 3, and the air cavity 2 is filled with the gas to be detected. The second duration may be a duration calculated by a technician through factors such as the volume of the airbag 3, the volume of the air cavity 2, the free diffusion speed of the gas, and the like, or a duration obtained by the technician through simulation software.
In the gas component measurement, the residual gas in the gas cavity 2 is discharged into the air bag 3, and the gas sensor 5 is started to measure the gas component after the residual gas in the gas cavity 2 is discharged, so that the accuracy of the gas component measurement can be improved.
By the above, the wearable device can be used for measuring the blood pressure data of the user, measuring the gas component data of the gas exhaled by the user, measuring the gas component data of the gas in the environment, improving the use function of the wearable device and enriching the application scene of the wearable device.
In one example, the wearable device further has a heat dissipation function, and correspondingly, as shown in fig. 3, the device body 1 further has a heat dissipation outlet 102, and an air channel 8 is connected between the air cavity 2 and the heat dissipation outlet 102; the air passage 8 between the air cavity 2 and the heat dissipation outlet 102 is respectively contacted with a plurality of heating elements in the equipment body 1, and the plurality of heating elements dissipate heat through the air passage 8 between the air cavity 2 and the heat dissipation outlet 102; an air outlet valve 11 is arranged on the air channel 8 between the air cavity 2 and the heat dissipation outlet 102 at a position close to the heat dissipation outlet 102, and a heat dissipation valve 12 is arranged on the air channel 8 between the air cavity 2 and the heat dissipation outlet 102 at a position close to the air cavity 2.
The processor 7 is used for controlling the opening and closing of the air inlet valve 9, the air bag valve 10, the air outlet valve 11 and the heat dissipation valve 12 and controlling the starting and stopping of the micro pump 6 to dissipate heat of a plurality of heating components.
The heating element may include a signal processing element 13, a power chip 14, a processor 7, an airbag valve control element 100, a micropump control element 61, a gas sensor control element 51, an intake valve control element 91, and the like.
During the heat dissipation process, the gas enters the gas cavity 2 and the air bag 3 through the vent 101 and is discharged through the heat dissipation outlet 102.
In an example, the air outlet valve 11 is opened and closed under the instruction of the processor 7, for example, as shown in fig. 3, the wearable device may further include an air outlet valve control part 111, the air outlet valve control part 111 is electrically connected to the air outlet valve 11 and the processor 7, the processor 7 may send an opening instruction and a closing instruction to the air outlet valve control part 111, and the air outlet valve control part 111 may control the air outlet valve 111 to open after receiving the opening instruction, so that the air in the air bag 3 and the air chamber 2 may be exhausted from the air passage 8 between the air chamber 2 and the heat dissipation outlet 102, and the air may take away heat generated on the heat generating component during flowing in the air passage 8 to dissipate heat of the heat generating component. The outlet valve controller 111 may control the outlet valve 11 to close after receiving the closing command.
Based on a similar process, the heat dissipation valve 12 is also opened and closed under the instruction of the processor 7, for example, as shown in fig. 3, the wearable device may further include a heat dissipation valve control element 121, the heat dissipation valve control element 121 is electrically connected to the heat dissipation valve 12 and the processor 7, and the processor 7 may control the heat dissipation valve to open and close through the heat dissipation valve control element 121. For example, the processor 7 may send an opening command and a closing command to the heat dissipation valve control element 121, and the heat dissipation valve control element 121 may control the heat dissipation valve 12 to open after receiving the opening command, so that the gas in the airbag 3 and the air cavity 2 may flow through the heat dissipation valve 12 in the air channel 8 to the heat dissipation outlet 102 to dissipate heat for the heat generating component. The heat dissipation valve controller 121 may control the heat dissipation valve 12 to close after receiving the closing command.
As described above, the processor 7 may be configured to control the opening and closing of the air inlet valve 9, the air bag valve 10, the air outlet valve 11, and the heat dissipation valve 12, and control the start and stop of the micro pump 6, so as to dissipate heat of the plurality of heat generating components.
Wherein, let the air flue 8 between air cavity 2 and heat dissipation export 102 pass as many heating element and part as possible, in passing, can take away the heat that produces on the heating element and part, and then for the heating element and part heat dissipation.
In one example, the processor 7 may control the air chamber 2 and the air bag 3 to be filled with air, and then control the air in the air chamber 2 and the air bag 3 to flow in the air passage 8. For example, when the processor 7 detects a signal for starting heat dissipation, the air outlet valve 11 and the heat dissipation valve 12 may be controlled to close and the air inlet valve 9 and the air bag valve 10 may be controlled to open, for example, the processor 7 may control the air outlet valve 11 to close through the air outlet valve control member 11, the heat dissipation valve 12 to close through the heat dissipation valve control member 121, the air inlet valve 9 to open through the air inlet valve control member 91, and the air bag valve 10 to open through the air bag valve control member 100. After the processor 7 has performed the respective valve control, the processor 7 may control the micro pump 6 to start, for example, by controlling the micro pump 6 to start through the micro pump control 61. When the processor 7 detects that the gas bag 3 is full of gas, the micro pump 6 is controlled to stop working, for example, the micro pump 6 is controlled to stop working by the micro pump control 61. Then, the processor 7 may control the air inlet valve 9 to close, and control the air bag valve 10, the air outlet valve 11 and the heat dissipation valve 12 to open, for example, the processor 7 may control the air inlet valve 9 to close through the air inlet valve control member 91, control the air bag valve 10 to open through the air bag valve control member 100, control the air outlet valve 11 to open through the air outlet valve control member 11, and control the heat dissipation valve 12 to open through the heat dissipation valve control member 121, so that the gas in the air bag 3 flows in the air passage 8 to dissipate heat for the heat generating component. When the processor 7 detects a signal of ending heat dissipation, the gas in the airbag 3 can be freely diffused and exhausted from the heat dissipation outlet 102, and then the processor 7 can control the airbag valve 10, the air outlet valve 11 and the heat dissipation valve 12 to be closed, for example, the processor 7 can control the airbag valve 10 to be closed through the airbag valve control member 100, the air outlet valve 11 to be closed through the air outlet valve control member 11, and the heat dissipation valve 12 to be closed through the heat dissipation valve control member 121.
The processor 7 may detect whether the air bag 3 is full of gas or not through a preset time period, for example, the processor 7 starts to time from the time when the micro pump 6 starts to operate, and when the third time period is detected, it may be determined that the air bag 3 is full of gas, that is, the third time period is a time period required for the air bag 3 to be full of gas. The third time period is similar to the first time period and the second time period, and may also be a time period calculated by a technician through factors such as the volume of the airbag 3, the volume of the air cavity 2, the free diffusion speed of the gas and the like, or a time period obtained by the technician through simulation software.
The processor 7 may use the temperature collected by the temperature sensor as a signal for determining the end of heat dissipation, for example, at least one temperature sensor is installed in the device body 1, and when the processor 7 detects that the temperature collected by the temperature sensor is lower than a temperature threshold, it may be determined that heat dissipation is ended. For another example, a temperature sensor is installed at each heating component, and when the temperature collected by these temperature sensors is lower than a temperature threshold, it may be determined that heat dissipation is finished. For another example, a temperature sensor is installed at several heating components that generate relatively large heat, and when the temperatures collected by these temperature sensors are all lower than a temperature threshold, it can be determined that heat dissipation is finished. For another example, the processor 7 may determine whether the heat dissipation is finished by the time length. The present embodiment does not limit the condition for determining the end of heat dissipation.
During the process of freely diffusing and discharging the gas in the airbag 3 through the heat dissipation outlet 102, the processor 7 may use a time duration as a condition for determining the end, for example, the processor 7 may start timing from the opening time of the gas outlet valve 11, when the fourth time duration is reached, it may be determined that the freely diffusing and discharging the gas in the airbag 3 through the heat dissipation outlet 102 is ended, and then, the gas outlet valve 11 is controlled to be closed. The fourth time period is similar to the first time period, and may also be a time period calculated by a technician through factors such as the volume of the airbag 3, the volume of the air cavity 2, the free diffusion speed of the gas, and the like, or a time period obtained by the technician through simulation software.
Wherein, this wearable equipment is full of gas earlier in the heat dissipation and is full of gasbag 3 and air cavity 2, then lets gas flow in air flue 8 again, can increase gaseous flow like this at the heat dissipation in-process, and a large amount of gas flow in air flue 8, can be fast effectual take away the heat on the heating element that air flue 8 passed, and then dispel the heat for heating element is quick, improve the radiating rate.
