Both the pulse sensor and the power supply are connected with the microcontroller. The portable sphygmometer has the technical advantages that 1) the portable sphygmometer adopting an electronic measurement and counting mode is favorable for precision measurement, and can realize more highly-efficient and reasonable judgment and analysis by the aid of modern tools, 2) the highly integrated system-level microcontroller is adopted, and the portable sphygmometer is simple in manufacture, fewer in elements, smaller in volume and convenient in use, and is carry-on, and 3) the portable sphygmometer is stable and reliable in operation and low in cost, realizes intuitive display, saves electricity, has fine application prospect, and can be used for measuring pulse rate at any time.
Description
Technical field
This utility model relates to a kind of pulses measure display device, belongs to pulse signal and measures the demonstration field.
Background technology
Pulse is the vital sign parameter that body weight for humans is wanted, and it directly reflects the health status of human body, in the traditional Chinese medical science still is Western medicine diagnose all in occupation of critical role.Traditional manual pulses measure error is bigger, can't Real Time Observation.If adopt the electronic surveying meter, help accurate measurement, can also by modern instrument carry out more efficient, reasonably judge and analyze.It is the portable electronic sphygmometer that the control core constitutes with the single-chip microcomputer based on piezoelectric transducer that a kind of portable electronic sphygmometer (application number is 201020210917.1) discloses a kind of.Producing its amplification and shaping circuit, fiducial time circuit, control single chip computer, count decoding display circuit adopts separating chips to realize that integrated level is not high.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of portable sphygmometer is provided.
Portable sphygmometer of the present utility model is made up of pulse transducer, microcontroller and power supply, and wherein pulse transducer, power supply all link to each other with microcontroller.
Preferably,
Said pulse transducer is selected the integrated pulse transducer of HKB type based on poly meta fluoroethylene piezoelectric film for use.
Said microcontroller is selected mixed-signal system level chip MSP430FG43x Series of MCU for use.
In this utility model, pulse transducer adopts the integrated pulse transducer of HKB type based on poly meta fluoroethylene piezoelectric film, it is a kind of soft contact damage-free type pulse transducer, this pick off piezoelectric type principle acquired signal, with the complete pulse wave voltage signal of analogue signal output, need during measurement pulse transducer is attached to the strength of human pulse.
Microcontroller adopts the mixed-signal system level chip MSP430FG43x Series of MCU of band LCD.Its RISC CPU can not only provide required signal handling capacity, but also has ultralow operating current, makes the life-span of battery in application can be for the several years.It chip internal integrated the LCD of amplifier, A/D converter and 128 sections.Microcontroller realizes setting pulse signal, count decoding and the display pulse number on LCD that sample frequency, amplification and shaping are gathered.
Because this device need be carried, so power supply employing button cell, be the microcontroller power supply.
Portable sphygmometer of the present utility model has following technique effect:
1) adopt the electronic surveying counting, help accurate measurement, can also by modern instrument carry out more efficient, reasonably judge and analyze;
2) adopt highly integrated system-level microcontroller, make simple, components and parts seldom, volume is littler, easy to use, can carry;
3) reliable, the intuitive display of working stability, with low cost and economize on electricity.Good application prospects is arranged, can measure Pulse Rate at any time.
Description of drawings
Fig. 1 is a structural principle block diagram of the present utility model.
The specific embodiment
As shown in Figure 1, portable sphygmometer of the present utility model is made up of pulse transducer, microcontroller and power supply, and wherein pulse transducer, power supply all link to each other with microcontroller, and power supply is powered to microcontroller.Pulse transducer is selected the integrated pulse transducer of HKB type based on poly meta fluoroethylene piezoelectric film for use.Microcontroller is selected mixed-signal system level chip MSP430FG43x Series of MCU for use.
The work process of portable sphygmometer of the present utility model is as follows:
The human pulse analogue signal that pulse transducer measures is amplified and shaping place to go noise signal by microcontroller, then through just going up the Pulse Rate that directly shows measurand from the LCD of microcontroller band by decoding circuit behind the microcontroller timer counter.
The above only is a preferable embodiment of the present utility model, not in order to restriction this utility model, all any modifications of being done within spirit of the present utility model and principle, is equal to and replaces and improvement etc., all should be included within the protection domain of the present utility model.
