Description
Technical field
The invention belongs to medical sanitary apparatus technical field, relate to a kind of energy consumption monitoring instrument, especially relate to a kind of portable physical consumption and physiological parameter monitor.
Background technology
Since entering 21st century, develop rapidly along with mankind's material progress, people's living standard significantly improves, correspondingly, threaten the disease of human health that great changes have also occurred, by early stage infectious disease to Chronic Non-Communicable Diseases---so-called " modern civilization diseases " or life style disease change, and the disease that these life style cause comprises diabetes, heart disease, apoplexy, hypertension and tumor etc.As poverty of movement (Physical Inactivity) can bring remarkable harm to health.American Heart Association just classified poverty of movement as the fourth-largest risk factor that changes as far back as 1992, the WHO of World Health Organization (WHO) also classifies poverty of movement as one of ten large reasons that cause the human mortality of developed country in its report in 2002, and approximately has 1,900,000 people's death relevant with poverty of movement every year.On the other hand, motion has important function to promoting health, and the motion of appropriateness can be health and brings many benefits.Data show regular motion especially physical training can make adult's Infant Mortality decline 20%～30%, can make the chronic disease sickness rate such as coronary heart disease, type ii diabetes, apoplexy decline 50%.Generally speaking, motion or physical training have improve cardio-pulmonary function, reduce blood fat, improve body immunity, slow down aging, elimination spirit anxiety and pressure, control body weight and improve the multiple effects such as build, multiple chronic disease is had to good facilitation as the rehabilitation of diabetes, hypertension, hyperlipidemia, metabolic syndrome simultaneously.
The popular people's of making of above these life style diseases concept of health has a very large change just, from early stage simple " prevent disease ", to " improving and promotion health ", changes---i.e. the primary prevention transformation to " utilizing various health promotion means to improve health status " by the secondary prevention of " early discovery, early treatment, early diagnosis ".
In sum, motion or physical training can promote health and become common recognition, moreover, researcheres are also found to have clear and definite dose-response relationship between motion and health, and this dose-response relationship all exists in the crowd of different sexes, all ages and classes.Therefore move and health between the research of relation or motion can just seem very necessary by accurate evaluation human body exercise amount while intervening.
Therefore, people will manage the quantity of motion in own daily physical training or motion, what first will solve is exactly the sports energy consumption problem how long-time continuous is measured under daily exercise condition, and this measuring method will have lower cost, want easy and simple to handle and applicable most user simultaneously.
(1) some conventional sports energy consumption measuring methods can partly solve the measurement problem of sports energy consumption, but still have significant limitation for the long-time continuous monitoring of sports energy consumption under daily exercise condition.
The concept of human motion (Physical Activity) is very wide, the people's such as the current received Caspersen of being CJ definition: " any body kinematics that causes energy expenditure being caused by Skeletal Muscle Contraction ".Here the body kinematics of indication can comprise the physical exertion (as work, housework, recreation etc.) of sports, athletic training, rehabilitation exercise and daily life.
Definition by human motion can find out have body kinematics just to have energy expenditure, and number and the energy expenditure of human motion are proportional.Researcheres are using energy expenditure as the how many objective basis of assessment quantity of motion for many years, and this is also the acknowledged momental a kind of objective judgement standard of assessment human body.In the last few years, researcheres, in order to assess accurately, quantitatively human energy expenditure, had successively adopted the several different methods such as questionnaire method, rhythm of the heart method, double labelling water law, indirect calorimetry, Biochemical Indexes method and sports apparatus.
The considerable epidemiological study about human body exercise amount assessment is the questionnaire method (Questionnaire) based on physical activity self-report formula, mainly contains diet record, recalls three kinds of forms such as formula questionnaire and personal interview.It mainly relies on experimenter's oneself explanation to momental record, experimenter self recalls the mistake of exercise frequency, exercise duration, and investigator or sporter self are the main causes that causes this method error to the mistake estimation of exercise intensity or load etc.Just because of objectivity and the poor distinct disadvantage of real-time of questionnaire method, make it can not meet the needs of on-the-spot real-time, the accurate monitoring human sports energy consumption of motion.
Rhythm of the heart method (Heart Rate Monitoring) is also applied comparatively extensively in human energy expenditure monitoring in recent years.As heart rate monitor common in training athlete, exercise, its principle is just that heart rate and sporter's oxygen intake and energy consumption have good linear relationship, can estimate the numerical value of sports energy consumption by the heart rate recording.But use the method still to have some defects: 1., along with the difference of the individual tolerance of experimenter, the relation of heart rate and oxygen intake is also changing; 2. the relation of same experimenter's heart rate and oxygen intake also be upper limb or lower extremity movement, be that static state or dynamic motion are relevant; 3. heart rate can be subject to the impact of a lot of other factorses, as posture and the environmental factors (temperature, humidity, height above sea level etc.) of heartbeat conditions (angry, frightened, nervous etc.), health.Therefore simple rhythm of the heart method can not be thought a kind of method of measuring accurately human energy expenditure.
Aspect human energy expenditure assessment, double labelling water law (Doubly Labelled Water) is to be used as " goldstandard " using always.Its principle is: experimenter takes in some concentration known
2h and
18two kinds of isotope-labeled two mark water of O (
2h
2 18o), two mark water enters after human body the metabolic process participating in body, the metabolism of (5-14 days) through after a while, according to
2h and
18the difference of two kinds of isotope elimination factors of O, can calculate the production rate of the interior carbon dioxide of body during this period of time, and then just can calculate energy expenditure.Because double labelling water law certainty of measurement is high, being therefore recognized is a kind of accurate method of measuring human energy expenditure.But double labelling water law also has larger limitation: first stable water isotope
2h
2 18o is very expensive, can not be obtained easily; And the method also needs complicated and expensive analytical tool, and the Measuring Time that often needs to grow (several days to several weeks).
Indirect calorimetry (Indirect Calorimetry), also can be described as respiration calorimeter method, in the research of sports medical science, also uses morely.It need to measure the amount of oxygen of inspiration and the carbon dioxide quantity of exhalation, and energy consumption is that gas exchange ratio calculates by the heat equivalent that oxygen expenditure amount is multiplied by nonprotein when breathing.During measurement, experimenter need dress the oronasal mask that respiration valve is housed, and collects the breath in human body certain hour, by being worn on the knapsack type gasometer of human body back, just can carrying out the energy consumption of certain hour and measure.Along with the progress of technology, Metamax and Cosmed K have been there is in recent years
4b
2deng portable gas metabolism tester, these portable equipments are lighter, can accurate analysis the gas exchange situation of each breathing under quiet and kinestate, and calculate energy expenditure.The method also has very high accuracy, can be used as the objective method of energy consumption assessment, is therefore usually used in evaluating validity and the reliability of other energy consumption evaluation method.Its limitation mainly contains: 1. portable gas metabolism tester price is higher, is difficult to popularize; 2. tester continuous working period is shorter, is generally no more than 5 hours; 3. the existence of oronasal mask and knapsack has certain obstruction for the daily exercise of human body.
Biochemical Indexes method is the sports energy consumption that the metabolite by producing in human motion process is estimated sporter.The lactic acid producing during as human motion just has substantial connection with skeletal muscle fiber type, exercise intensity and persistent period.Therefore athlete, instruct 00, during often by the front peace and quiet of detection campaign, after blood Lactate and motion, blood lactic acid peak value judges its quantity of motion size and training effect.In addition, the urine creatine in urine is the metabolite of the interior phosphagen of human body or creatine, also can be used as training effect or momental evaluation index.In general, Biochemical Indexes method mostly needs blood drawing to measure the metabolite after human motion, not only has wound, but also must just can provide result through the mensuration of relevant biochemical instrument, uses comparatively inconvenience.And also can produce certain measurement cost by the method assessment human body exercise amount.
Other as the sports apparatus such as pedometer, cycle ergometer, treadmill be to assess human energy expenditure by sporter's movement velocity and move distance mostly.These sports apparatus are estimating motion energy consumption roughly, can instruct to a certain extent motion.But sports apparatus often can only be assessed the sports energy consumption of single movement type, and not strong with sporter's individual variation dependency, can not meet people's needs that sports energy consumption is measured when outdoor sport.
As seen from the above, although the conventional measuring methods such as questionnaire method, rhythm of the heart method, double labelling water law, indirect calorimetry, Biochemical Indexes method and sports apparatus can be measured the sports energy consumption of human body to a certain extent, but all there are limitation and deficiency separately, can't provide a kind of measuring method simple and easy to do, objective, practical and with low cost for the long-time continuous monitoring of human energy expenditure under daily exercise condition.
(2) the sports energy consumption measuring method based on three dimension acceleration sensor has demonstrated the good prospect of monitoring human sports energy consumption under daily exercise condition.
In recent years, many researcheres were by experimental results demonstrate: the absolute value of human motion acceleration is linear to the integration of time and energy or oxygen consumption.This is just for utilizing the method assessment human energy expenditure based on acceleration transducer that concrete theoretical foundation is provided.
Original research persons have adopted the one-dimensional acceleration transducer of vertical direction to carry out the research of human energy expenditure assessment aspect, but one-dimensional acceleration transducer has significant limitation.In human motion, except normal acceleration, also have the acceleration of horizontal direction, the acceleration of trunk rotation etc., when experimenter wears one-dimensional acceleration transducer and measures, the output meeting of acceleration transducer is more on the low side than objective value, and error is larger.
Consider the weak point of one-dimensional acceleration transducer measurement human energy expenditure, researcheres had tended to adopt more complicated, more accurate three dimension acceleration sensor to measure human energy expenditure in recent years.The skew of three dimension acceleration sensor on each direction of measurement is the same with sensitivity.And between the output of three dimension acceleration sensor and energy consumption, there is better linear relationship, also there is good repeatability and reliability.
At present, the monitor that can complete sports energy consumption assessment based on acceleration transducer of domestic independent development is also fewer, and mostly is the product based on one-dimensional acceleration transducer.
Motion energy consumption monitor based on one-dimensional acceleration transducer is as early stage " intimate energy monitoring instrument ", this instrument is according to kinesiology's principle, use acceleration transducer to gather body motion information, through microprocessor analysis, calculating, processing, the kinergety consumption of human body is presented in LCDs in digital form, and user can understand in time quantity of motion and whether dietary amount is suitable.
But the motion energy consumption monitor of this class based on one-dimensional acceleration transducer has significant limitation.In human motion, except normal acceleration, also have the acceleration of horizontal direction, the acceleration of trunk rotation etc., when experimenter wears one-dimensional acceleration transducer and measures, the output meeting of acceleration transducer is more on the low side than objective value, and error is larger.
The instrument for the movable energy consumption monitoring of human physical power of the moving motion energy consumption monitor Shi You Beijing Xin Huier Health Co., Ltd of FitPod health and Sport Science Inst., State Sport General Bureau's cooperative development, adopt MEMS 3-axis acceleration sensor, intelligent fuzzy identification and energy consumption model technology, can adopt the energy expenditure of the calculated with mathematical model motion unit of proofreading and correct through sex, age, height and body weight.The moving motion energy consumption monitor of health can monitor the sports energy consumption data of human body under different exercise intensitys, and analyzes fatty and sugared consumption ratio.
Excessive and body constitution is poor, even have heart disease, the sporter of hypertension chronic diseases for componental movement, they occur that in motor process the unexpected even dangerous probability of motion is larger.To these special populations, the medical supervision in their motor process becomes an important problem.For this point, the energy consumption measurement instrument that is similar to the moving motion energy consumption monitor of health does not also provide corresponding solution.

The specific embodiment
Below in conjunction with the accompanying drawing specific embodiment, method of the present invention is described in more detail.
As shown in Figure 1, acceleration transducer, digital blood oxygen module and signal condition cell formation intrasystem forward path, the data of the physiological parameters such as the exercise data of human body and blood oxygen saturation, heart rate enter central control unit by forward path.
Central control unit has adopted the 16 8-digit microcontroller MSP430F149 (hereinafter to be referred as F149) with super low-power consumption feature, its Embedded has the A/D modular converter of 8 Channel 12-Bit precision, the FLASH ROM of 60KB and the data RAM of 2KB, and has hardware multiplier and 2 serial communication interfaces.Adopt MSP430F149 chip as the central control unit of native system, can be outside without sheet realize collection, reception and the processing of motor message and various physiological signals on the basis of A/D chip.Promote advance, reliability and the integrated level of system, promoted largely the overall performance of system.
The data such as three-dimensional motion data, blood oxygen saturation and heart rate that data storage cell can long-time continuous storage of collected arrives.
Display And Keyboard interface unit provides the keyboard interface that arranges and operate this monitor, and realize the demonstration of Chinese word function menu, sporter's physical consumption and the numerical value Presentation Function of physiological parameter by graphic dot matrix liquid crystal, for system provides friendly and intelligentized human-computer interaction interface.
Clock unit provides real-time time coordinate for system, so can provide for the storage of data can reference starting and ending time point.
Data communication units provides the means of the exchanges data between this monitor and PC, has adopted the data communication mode based on USB (universal serial bus) (USB), has the advantages such as transmission speed is fast, support hot plug.
Power subsystem is the analogy and digital circuit part power supply respectively in monitor, and different running voltages and certain power supply partition management functions are provided.
Acceleration transducer can reflect intensity and the frequency of human motion, the various kinestates of human body can be converted to the voltage signal of different amplitudes, and its simple installation, volume are little, are the more suitable motion sensor component in portable physical consumption and physiological parameter monitor.
For the daily exercise of human body, the measuring range of its acceleration of motion is: amplitude-6g～6g, frequency 0～20Hz.In order to reflect exactly human motion situation, in this monitor, adopted three dimension acceleration sensor to gather human body three-dimensional movable information.
In native system, adopted Static and dynamic has been encouraged to the piezoresistance sensor that all has better response, can not only measure acceleration of gravity, acceleration of motion, continue transient oscillation, can also measure inclination angle and orientation.
This monitor has adopted the 3031-050 type acceleration transducer of three GeIC Sensors companies to be combined into orthogonally a three dimension acceleration sensor, the side direction while measuring human motion respectively, vertically to sagittal acceleration.3031 adopt surface encapsulation form, and volume is little: its size is only 7.6mm * 7.6mm * 3.6mm, lightweight: only have 0.3 gram.3031-050 type sensor useful range is ± 50g, built-in vibration abatement.Can use single 5V Power supply, frequency response range is 0～1000Hz, the about 1mV/g of sensitivity, and nonlinearity is only 0.5%, operating temperature-40～+ 125 ℃.This sensor can meet the requirement of acceleration analysis in native system preferably.
While measuring human motion acceleration with acceleration transducer, positive direction is defined as the end face perpendicular to 3031 sensors, and upwards draws from end face.Acceleration transducer is worn on human body, and its end face is towards human body the place ahead, when human motion acceleration static forward time, measurement be a positive acceleration, when human motion, slow down, measure a negative acceleration.
To acceleration transducer, output voltage when zero-bit output voltage is defined as static and its strain beam of sensor and gravity direction quadrature without angle, output when acceleration is absolute 0g.But each acceleration transducer is after dispatching from the factory, its zero-bit output voltage generally has a skew (offset), and this skew can just can be born, and is generally several millivolts.This skew that the zero-bit of degree of will speed up sensor is exported when non-vanishing is called zero drift.For guaranteeing the precision of this monitor, must compensate the zero drift of sensor (being zero compensation).
In native system, the method for zero compensation is: the static placement of laying state (as placing vertically) by monitor during by actual use, to side direction now, vertically to compensating to the sensor output in three directions with front and back, makes it be zero.
Signal condition unit specifically comprises signal amplification circuit, filter circuit and standard of precision voltage circuit etc., mainly realizes the functions such as amplification, shaping and filtering of signal.
The prime connecting due to signal condition unit is human motion signal to be converted into the acceleration transducer of the signal of telecommunication, what level connected thereafter is the A/D modular converter in MSP430F149, the effect of signal condition unit is that the weak voltage signals of sensor output is amplified without distortion or adjusts to the enough voltage signals of amplitude that can directly be sampled by A/D modular converter, and signal condition unit is as much as possible little on the impact of the A/D modular converter of the sensor of its prime and rear class.
For the useful differential signal that effectively amplification sensor is exported, signal amplification circuit in signal condition unit should have stronger common mode inhibition and differential amplifying power, actual common mode inhibition is higher, input impedance is larger, imbalance and temperature are floated less, these can effectively reduce the impact of signal amplification circuit on sensor input signal, reduce temperature error.Native system adopts the single supply of LiaoTI company, the precision instrument amplifier INA122 of micro-power consumption.
In this monitor, adopted the Surface Mount packing forms INA122 chip of 3 S0-8, the sensor output of 1 corresponding signalling channel of INA122 amplifier.In order to obtain alap noise, to three INA122 circuit corresponding to three signalling channels respectively between its power end (7 foot) and ground (4 foot) as far as possible near-earth connect the decoupling capacitor of a 0.1 μ f.
In this monitor, the frequency range of human motion acceleration signal mainly concentrates on 0～20Hz, for the unwanted frequency composition in filtering amplifying circuit output signal, need to after signal amplification circuit, add a 20Hz low-pass filter circuit.This low pass filter both can be eliminated aliasing before sampling, and the high-frequency harmonic of being introduced by switching power circuit in filtered signal in advance again plays the effect of eliminating noise.
Filter circuit has adopted the active filter forming with the accurate amplifier of phase structure and RC network, and certain gain and cushioning effect can be provided like this, can reduce again the impact on the conversion of rear class especially A/D.
In system, selected the second-order low-pass filter of Butterworth type, the decay of its can provide-40db/ ten octaves in stopband.The flat region of Butterworth mode filter is larger, in its passband, there is no ripple, and phase-frequency characteristic can be thought linear within the specific limits.The selection of amplifier also has impact to the precision of wave filter.Open-loop gain and the gain band width product of selected amplifier are larger, and the too small closed loop gain KP of filter circuit that directly causes of open-loop gain and input impedance reduces, and damped coefficient δ increases, thereby reduce the precision of wave filter.And the too small closed loop frequency band that not only makes of gain bandwidth product narrows down, amplitude and phase error have also been strengthened.So select the amplifier of higher quality to there is important function to ensuring the precision of source filter.
When power filter is installed, should note the matching precision of resistance, to improving its common mode rejection ratio also highly significant.
Acceleration signal is after second-order low-pass filter filtering, and its output signal is as the signal source of the acquired signal of A/D change-over circuit, because its output resistance is less, also less to the Accuracy of A/D conversion.
Because the artificial circuit part of this monitor adopts single 5V Power supply, and lower limit and the upper voltage limit of native system while adopting respectively 0V and 2.5V voltage to change as A/D, the full scale amplitude that signal amplifies is 0V～2.5V.Actual effective range after signal amplifies is 0～1.25V (negative acceleration signal) and 1.25V～2.5V (positive acceleration signal).Therefore in whole signal condition unit, need the standard of precision voltage of a 1.25V.
In system, adopt the LM385-1.2 voltage reference circuit with micro power consumption of LiaoTI company.Its reference voltage providing is 1.235V (representative value).This circuit can provide the operating current of 15 μ A～20mA, has extremely low power consumption, extremely low motional impedance and good temperature stability, low noise and for a long time job stability.
In order to make this reference voltage circuit and the isolation of analog circuit other parts, the reference voltage of LM385-1.2 output is exported through a follower.
The digital blood oxygen module of this monitor has adopted the DigiSat blood oxygen saturation module of Beijing Mai Chuantongyuan Electron equipment Co., Ltd, this inside modules has adopted 32-bit microprocessor, utilizes the method for Digital Signal Processing can measure exactly arterial oxygen saturation.Even signal to noise ratio lower (as motion or weak perfusion) in the situation that, also can obtain oximetry value more accurately.
DigiSat blood oxygen saturation module can provide arterial oxygen saturation numerical value (0-100), pulse rate numerical value (30-250), characterize patient's pulse beat situation plethysmogram numerical value (0-100), characterize pulse beat situation excellent figure numerical value (0-15) and characterize the numerical value (0-8) of the signal intensity of patient's perfusion state.
DigiSat blood oxygen saturation module is by asynchronous serial communication mouth and the MSP430F149 micro-controller communications of a Transistor-Transistor Logic level.This blood oxygen saturation module can send the packet that length is 5 bytes incessantly to MSP430F149 microcontroller, sends each second 60 times.The communications protocol of DigiSat blood oxygen saturation module and BCI communications protocol are compatible, and speed during serial communication is 4800 baud rates, and data format is 8 bit data positions, 1 odd parity bit and 1 position of rest.
DigiSat blood oxygen saturation module has two interfaces to be connected with main frame with blood oxygen probe respectively.P1 mouth comprises that the driving of probe and signal receive.P2 mouth comprises power supply and the connecting line of communicating by letter.
In portable physical consumption and physiological parameter monitor, the power consumption of central control unit (hereinafter to be referred as microcontroller or MCU) is also one of important sources of entire system power consumption, be chosen in the microcontroller in the design of micro-power consumption with outstanding advantage, for micro-power consumption design of system, there is very real effect.Meanwhile, the microcontroller of selecting to be integrated with degree of precision A/D modular converter and larger capacity data RAM can effectively reduce system design difficulty and improve the reliability of system.
In native system, adopt the MSP430F149 microcontroller (being designated hereinafter simply as F149) of LiaoTI company.The power consumption of this microcontroller has reached microampere order, is 16 MCU with super low-power consumption feature.F149 inside is integrated with multichannel, high-speed a/d modular converter ADC12, and the A/D conversion of 8 Channel 12-Bit precision can be provided, and its maximum sampling rate can reach 200ksps.The ADC kernel, conversion stored logic, internal reference level generator, multiple clock source, sampling and the conversion timing sequence circuit that in ADC12 module, comprise sampling/maintenance function.For this monitor, the inner integrated ADC12 module of F149 just can meet the requirement of data acquisition well.
In addition, the inner integrated serial communication module of F149 is not only supported asynchronous serial communication, also supports SPI synchronous communication mode, and this is just for F149 accesses DigiSat blood oxygen saturation module and serial FLASH memory provides the assurance on hardware.
Meanwhile, in F149, be integrated with the data RAM of 2KB, can provide enough buffer time for data being write to FLASH memorizer, can meet preferably the needs of real-time data acquisition and the reliability of raising system.
The software configuration of F149 also designs for low-power consumption.As waken MCU up from standby mode, only need 6 μ S.It interrupts and subroutine call limits without level, and this abundant interrupt capabilities has reduced the needs of system queries, can design easily the system control program based on interrupt structure.
In sum, MSP430F149 microcontroller has extremely low power consumption, has peripheral module on the powerful sheet of several functions.F149 has adopted the Surface Mount encapsulation of QFP64 simultaneously, and pin-pitch is only 0.5mm, has saved significantly circuit board space.Adopt MSP430F149 as the microcontroller of this monitor, increased advance and the integrated level of system, promoted the overall performance of system.
MSP430F149 inside is integrated with multichannel, high-speed a/d modular converter ADC12, by ADC12 module complete to side direction, vertically to and front and back to the A/D of acceleration signal, change, by through amplifying, the acceleration signal analog quantity of filtering is converted to digital quantity.
ADC12 has four kinds of translative mode: single channel single conversion, single channel repeat conversion, sequence of channels single conversion, sequence of channels and repeat conversion.To native system, side direction, vertically to and front and back to the input signal of acceleration signal, need to once change completely, adopt sequence of channels single conversion mode comparatively suitable, its sequencing contro is simple, reliability is higher.
The approximately 5MHz clock that change over clock in native system has adopted internal oscillator ADC120SC to produce.
In native system, acceleration output signal is 0V～2.5V through amplification, filtered dynamic range, and the full scale sample range of signal should be also 0V～2.5V.Therefore the datum of ADC12 should match therewith, and getting VR-is 0V, and VR+ is 2.5V.Adopt the inner integrated datum generator of ADC12 to provide sampling required reference voltage simultaneously.
In daily exercise, the frequency range of acceleration signal is 0～20Hz, and in conjunction with the requirement of nyquist sampling law, system is decided to be 100Hz sample frequency.
In design, in order effectively to reduce each interchannel crosstalking, by the side direction of needs collection, vertically to and front and back to acceleration signal respectively one, interval sampling channel be linked into ADC12, side direction signal connects the A1 passage of ADC12, vertically to signal, connect A3 passage, front backward signal connects A5 passage.A0, A2, A4, A6 passage be earth lead all, and a ground wire is accessed respectively on each signalling channel both sides like this, has played isolation and shield effect, has effectively avoided the generation of crosstalking, and in actual use, effect is fine.Also make not have the A/D input pin of use not unsettled, avoided the introducing of disturbing and reduced power consumption simultaneously.
Low-power consumption management in A/D conversion is to realize by control bit and the A/D converse routine of control register.ADC120N control bit in ADC12 can be controlled the open and close of A/D kernel.REFON control bit can open and close inner datum generator.In native system, for further reducing power consumption, after ADC12 starts once to sample, MCU enters low-power consumption mode, and by A/D conversion interrupt identification, ADC12IFG wakes MCU up, carries out the storage of data.
In design, comprehensively, to the considering of the factors such as power consumption, control mode, display area, in system, adopted the MG-12232 LCD MODULE of letter profit (TRULY) company.MG-12232 module can be operated in 2.7V～4.5V, and the representative value of operating current is 0.3mA, is well suited for the low-power consumption environment of native system 3V level, has also avoided conventional 5V Liquid Crystal Module and the unmatched problem of MSP430F149 single-chip microcomputer logic level simultaneously.
