Description
Technical field:
the utility model relates to a kind of novel domestic intelligent blood glucose meter, is specifically related to a kind of domestic intelligent blood glucose meter based on master controller STM32.
Background technology:
The family expenses blood glucose meter performance that
occur in the market is comparatively single, on the high side, and the application scenario is single.
Summary of the invention:
The purpose of
the utility model provides a kind of intelligent degree height, uses simple novel household intelligence blood glucose meter.
Above-mentioned purpose realizes through following technical scheme:
a kind of novel household intelligence blood glucose meter; Its composition comprises: microprocessor STM32, information acquisition device, power circuit, clock circuit, display circuit, Keyboard Control module, described information acquisition device, described power circuit, described clock circuit, described display circuit, described Keyboard Control module all are connected with described microprocessor STM32.
Beneficial effect:
this blood glucose meter provides multiple modes of operation to adapt to the application of different occasions; Mmol/L is provided (milli rub/liter) in addition; Mg/dl (mg/litre), more convenient use is changed in freely switching also of three kinds of common measuring units of g/l (grams per liter) automatically.So, confirm that this relation is the very corn of a subject.But it concerns complicated, receives many-sided factor affecting.The blood flow volume of voltage strength, employed strip and detection all can exert an influence to it.Need on all concentration point, test in a large number in theory and could confirm final relation.In practical operation, only need selecting some important concentration point do a large amount of experiments, adopt data processing methods such as curve fitting or interpolation to confirm the relation between itself and the current value then.
Description of drawings:
accompanying drawing 1 is the structural representation of this product.

Embodiment 2:
are according to embodiment 1 described novel household intelligence blood glucose meter; Described microprocessor STM32 is the processor of system, and STM32 series is based on aiming at the custom-designed ARM Cortex-M3 of the Embedded Application that requires high-performance, low cost, low-power consumption kernel.Be divided into two different series: STM32F103 " enhancement mode " series and STM32F101 " basic model " series by performance.Enhancement mode series clock frequency reaches 72MHz, is the highest product of performance in the like product; The basic model clock frequency is 36MHz, obtains the performance that significantly promotes than 16 products with the price of 16 products, is the optimal selection of 16 product users.Two built-in 32K of series are to the flash memory of 128K, and different is the combination of max cap. and the Peripheral Interface of SRAM.During clock frequency 72MHz, from the flash memory run time version, STM32 power consumption 36mA is a product least in power-consuming on 32 markets, is equivalent to 0.5mA/MHz.
Embodiment 3:
according to embodiment 1 described novel household intelligence blood glucose meter, described information acquisition device is the core of system design, and blood glucose measurement adopts the three-electrode system in the electrochemical analysis usually.Three-electrode system is for the traditional two-electrode system, comprises working electrode (WE), contrast electrode (RE) and to electrode (CE).Contrast electrode is used for fixed point position zero point, and flow through working electrode and electrode working electrode and contrast electrode constituted an obstructed or basic few system of switching on of electric current utilizes the stability of contrast electrode current potential to come the electrode potential of surveying work electrode.Working electrode and auxiliary electrode constitute the system of an energising, are used for the electric current that the surveying work electrode passes through.Utilize three electrode measurement systems, come the some position of the electrode of research work simultaneously and the relation of electric current.
Embodiment 4:
are according to embodiment 1 described novel household intelligence blood glucose meter; Described power circuit; The common alkaline AAA battery of two joints is adopted in the power supply design, utilizes RT9701 (panel switches) and RT9266 (boost conversion chip) to form efficient booster circuit and boosts to the power supply of 3.3V as whole blood glucose meter.On the power supply circuit construction of whole instrument; The designing power supply on-off circuit; Can be with real-time clock when when shutdown directly through the powered battery except STM32, the power supply of other circuit is all cut off, and makes entering dormancy of STM32 and real-time clock or electricity-saving state then; Can save the power consumption of standby greatly, prolong the service time of battery.STM32 wakes up through interrupting realizing that button of generation interrupts when switch key is pressed, and wakes STM32 thus up and is other circuit energized, blood glucose meter rearming.
Embodiment 5:
are according to embodiment 1 described novel household intelligence blood glucose meter, described clock circuit, its real-time clock design, employing s-3530A real-time timepiece chip.This real-time clock has the characteristics of high-precision low-power consumption, work crystal oscillator frequency 32K, and be provided with energy-saving mode, and can when blood glucose meter is idle, make it get into energy-saving mode, save battery electric quantity.Adopt the I2C bus to be connected, effectively save single-chip processor i/o mouth line with single-chip microcomputer.Automatically calculate the leap year, and represent the date time data, for the read-write of STM32 provides great convenience with the binary-coded decimal form.
Embodiment 6:
according to embodiment 1 described novel household intelligence blood glucose meter, described display circuit for good man computer interface is provided, strengthens the monitoring function native system and has adopted the liquid crystal display displays electrocardiosignal in blood glucose meter.Because that LCD (LCD) has is low in energy consumption, volume is little, the incomparable advantage of many other displays such as in light weight, ultra-thin, is widely used in recent years in monolithic processor controlled intelligence instrument, instrument and the low power dissipation electron product.LCD can be divided into section formula LCD, character formula LCD and lattice type LCD.Wherein, section formula LCD and character formula LCD can only be used for the simple displaying of character and numeral, can not satisfy the requirement that graph curve and Chinese character show; And lattice type LCD not only can character display, numeral, can also show various figures, curve and Chinese character, and can realize that screen rolls up and down, animated function, the subregion windowing, counter-rotating, functions such as flicker, purposes are very extensive.LCD is selected MGLS12864 for use, and it is 128 * 64 dot pattern displays, and the dot matrix requirement to LCD at first is discussed.According to the standard recording specification of ordinary electrocardiogram, promptly chart drive speed is 20mm/s, and amplitude gain is 10mm/mV.In conjunction with the sampling rate of native system 200Hz, the input voltage range of 5mV and 1000 times gain.
Embodiment 7:
are according to embodiment 1 described novel household intelligence blood glucose meter; Described Keyboard Control module, keyboard are indispensable peripherals in the SCM system, and operating personnel can carry out data input, output through keyboard; Program generates, operations such as program execution.It is an interactive important tool.Connected mode according to keyboard and single-chip microcomputer can be divided into free-standing keyboard and matrix keyboard.The stand alone type keyboard is that each button is separate, and each button takies an I/O mouth line, and the button duty on every I/O mouth line can not influence button duty on other I/O mouth lines.Stand alone type keyboard circuit flexible configuration, software configuration is simple, but each button must take an I/O mouth, and more for a long time, the waste of I/O mouth line is bigger, and circuit structure seems numerous and diverse in number of keys.Because the Keyboard Control of native system only need realize the demonstration of electrocardiosignal, storage, and playing function, its control is simple, so use free-standing keyboard to accomplish the control to single-chip microcomputer.
