A kind of Intelligent blood sugar instrument of slotting strip Auto Power OnTechnical field
The present invention relates to a kind of Intelligent blood sugar instrument, more particularly to a kind of Intelligent blood sugar instrument of slotting strip Auto Power On.
Background technology
Traditional blood glucose meter currently on the market is mostly without intelligent operating system, by gathering blood glucose strip and blood chemistryMicro-current signal of change afterwards goes out blood glucose value.Possesses function：Insert strip Auto Power On and enter measuring state, can be locally stored fewTest result is measured, minority can be with synchrodatas such as computer, mobile phones with communication functions such as serial ports, USB, bluetooth, WIFI.In order toMeasurement is precisely and cost is cheap, and the microprocessor that traditional blood glucose meter typically employs ADC of the integrated precision more than 12 goes to adoptCollect the microelectric signals of blood glucose biochemical reaction.It is to have an insertion detecting electrode and one in strip that it, which inserts strip Auto Power On principle,Individual ground electrode, two electrodes are in the conduction state in strip.The corresponding position of strip socket in blood glucose meter, ground electrode correspondenceThe ground of blood glucose meter, the insertion detection pin of insertion detecting electrode correspondence blood glucose meter.Electric Auto Power On in blood glucose meter, as long as having electricity justDo not shut down, nothing is operated into sleep state in a period of time.Insertion detection pin acquiescence has pull-up for high level, and microcontrollerThere is provided trailing edge interrupts detection.After strip is inserted, insertion detection pin will be dragged down with ground conducting, be produced in trailing edgeIt is disconnected, also just allow blood glucose meter microcontroller interrupt to wake up, then the related work such as processing measurement.
Smart mobile phone is quite popularized currently on the market, year shipment amount more than 1,000,000,000, technology is quite ripe.Intelligent handMachine employs intelligent mobile operating system (such as Android, WindowsPhone, iOS), user can very aspect on mobile phoneEntertained, made friends, done shopping, obtained information, more new application is convenient to, be easy to application developer to continue to optimizeProgram.Intelligent mobile equipment is hereinafter simply referred to as using the equipment of intelligent mobile operating system.
The application software of traditional blood glucose meter is fairly simple, exists to network and automatically updates program, is simply possible to use in measurement bloodSugar and blood glucose can not be managed, can only store the deficiencies such as a small amount of measurement data.
The present inventor combines traditional blood glucose meter and Intelligent mobile equipment, designs Intelligent blood sugar instrument by being continually striving to,The application obscure portions such as the blood glucose measurement part of traditional blood glucose meter and data management, interface display are separated, blood glucose measurement part is adoptedWith with the design traditional blood glucose meter, it is ensured that measurement it is accurate.In the system of application obscure portions Intelligent mobile equipment, Ke YihaiStorage management data are measured, while abundant using that can also be made, and can also continuous upgrade maintenance.While this Intelligent blood sugar instrumentAlso support that inserting strip Auto Power On enters measuring state, improves Consumer's Experience.
The content of the invention
It is an object of the invention to provide the slotting strip Auto Power On that a kind of slotting strip energy Auto Power On enters measuring stateIntelligent blood sugar instrument.
