Blood glucose monitoring system
Technical field
The utility model is related to medical instruments field, particularly blood sugar monitoring field.
Background technology
China's onset diabetes rate is in rising trend, and with the improvement of people's living standards, the change of living environment, sugar
The sick age of onset of urine increasingly tends to rejuvenation, the male of Chinese middle-aged adults, particularly 30 ~ 40 years old, the proportion of diabetic
Increasingly increase.
There is short slab in terms of the blood glucose level data of long-term record analysis user in traditional blood glucose meter, and various smart machines into
Indispensable object in for modern life, such as mobile phone, panel computer.The blood sugar number that blood glucose meter sends is received using smart machine
According to, user record, analyze data can be effectively helped, find the rule of blood glucose fluctuation.
The usual way for being communicated with smart machine at present has USB interface communication, bluetooth or GPRS wireless telecommunications etc..But city
USB interface is different on face, it is impossible to unified, and wireless communication mode is relatively costly, therefore can avoided using COBBAIF
Data communication is realized on the basis of above mentioned problem.
The content of the invention
The blood glucose monitoring system that the utility model is provided, by 3.5mm earphone interfaces carry out blood glucose meter and smart machine it
Between data transfer, shown by smart machine, record data.
To reach above-mentioned technique effect, the utility model uses following technical proposals:
Blood glucose monitoring system, including blood glucose meter main body and smart machine, blood glucose meter main body include blood sugar test module, test paper
Module, power supply module, thermal module, it is characterised in that the blood glucose meter main body also includes voice communication module, 3.5mm earphones
Plug.The R channel of the 3.5mm headset plugs(2)For inserting wake-up device during smart machine, L channel(1)For receiving
The data that smart machine sends, microphone port is used to send the data of blood glucose monitoring system.The voice communication module passes through
Customized data framing protocol is set up with smart machine and is connected and transceiving data.The voice communication module is by sending and receiving
The square wave of two kinds of different frequencies realizes data communication, and the square wave of one of which frequency represents data 1, the square wave generation of another frequency
Table data 0.The smart machine is the computer with 3.5mm earphone interfaces, smart mobile phone or panel computer.
Compared with prior art, the beneficial effects of the utility model are:
1st, the display in traditional blood glucose meter equipment and operation module are eliminated, display are completed using smart machine and is operated,
Significantly save cost.2nd, compared with other Intelligent blood sugar instrument transmitted using modes such as bluetooth, GPRS, voice communication unit consumption
Electricity is less, saves battery, beneficial environmental protection, and price is relatively low.The 3 Intelligent blood sugar instrument phases that audio transmission data are used with other
Than the technical program is not used sine wave, is directly transmitted using square wave, reduces the process that square wave is converted into sine wave, more
Accelerate prompt, save circuit cost.4th, shown using smart machine by data communication, record, analyze blood glucose level data, be easy to blood sugar
Management, brings the behavior that the state of an illness is managed use habit of the Chinese middle-aged adults in terms of smart machine into.

Specific embodiment
Specific embodiment of the present utility model is introduced below in conjunction with the accompanying drawings:
As shown in figure 1, blood glucose monitoring system includes blood glucose meter main body and smart machine, blood glucose meter main body includes blood sugar test
Module, thermal module, power supply module, test paper module, voice communication module, 3.5mm Earphone joints.
As shown in Fig. 2 blood glucose meter main body is set by the intelligence that 3.5mm headset plugs are inserted with receiver J-Horner during measurement
It is standby, the R channel of 3.5mm headset plugs(2)For waking up smart machine, L channel(1)Number for receiving smart machine transmission
According to microphone port(3)(Meet OMTP national standards)Or microphone port(4)(Meet CTIA international standards)For sending blood
The data of sugared instrument main body.The system compatibility meets the 3.5mm Earphone joints of CTIA international standards and OMTP national standards.
The voice communication module of blood glucose meter main body is by voice communication module by customized data framing protocol and intelligence
Equipment sets up connection and transceiving data.Data communication sends and receives two kinds of square wave realities of different frequency by voice communication module
Existing, the square wave of one of which frequency represents data 1, and the square wave of another frequency represents data 0.As shown in figure 3, in the present embodiment
1.3Khz (± 100hz) and 650hz is selected(±100hz)The square wave of two kinds of square waves of frequency, wherein 1.3Khz frequencies is represented
Data 1;The square wave of 650hz represents data 0, and data transfer is realized by the binary number of data 0 and 1.Defined in the present embodiment
Data framing protocol be:Serial data 000000000000 releases the effect that audio is fade-in fade-out, and data head 1110 represents data hair
Send and formally start, be followed by the data of the binary number composition of two eight, and according to the odd number of this data placement one
According to 0 or 1, stop bits 1111 represents that data is activation is completed.
The definition of data framing protocol and the selection of two kinds of square wave frequencies be not unique, in the present embodiment choose square wave frequency and
Digital Frame Protocol is only wherein preferred one kind.
Although the utility model is disclosed as above with preferred embodiment, embodiment and accompanying drawing are not for limiting this reality
It is any to be familiar with this those skilled in the art with new, in the spirit and scope for not departing from the utility model, can make various changes or moisten from working as
Decorations, but it is same within protection domain of the present utility model.Therefore protection domain of the present utility model should be with the power of the application
What the claimed scope of profit was defined is defined.
