Method.Medical Instruments is generally used for clinic, such as using the electrocardiogram of computer acquisition patient, the principal character of identification signal, sentence
Breaking, whether normal it is and in time for doctor provides information.
Biomedicine signals include various biological parameters, such as：The bioelectrical signals such as brain electricity, electrocardio, muscle；Heartbeat, blood pressure,
The non-electric charge quantity signallings such as breathing, body temperature, CBF, pulse, heart sound.These signals are the faint letters of low frequency under strong noise background
Number, to the processing procedure of these bio signals be first be acquired, shaping is amplified, A/D conversions, single-chip microcomputer treatment, D/A turn
Change, store, print, show.
Body temperature is diagnosis patient and the important parameter guarded to patient, medical science or daily life
In human body temperature is generally gathered using thermometer, nowadays as the development of digital clinical thermometer gradually instead of traditional mercury temperature
Degree meter.At present, the main point for measuring temperature of the common digital clinical thermometer of in the market in the liquid crystal type clinical thermometer and point for measuring temperature of cochlea in forehead
Infrared type clinical thermometer, both clinical thermometers using Gao Hong numeral method temperature, display is clear, and accuracy of reading can be kept away
Exempt from the error that mercurial thermometer range estimation brings, it also avoid liquid crystal thermometer the characteristics of reading is difficult under high light daytime, and
It is more more environmentally friendly than mercurial thermometer.But, correlative study shows that cochlea and the temperature of forehead easily receive environment temperature compared with auxillary temperature
The influence of degree, and it is unstable, so cochlea and forehead are not the optimal sites for reacting human body temperature.

Preferably, the buffer is 74LS244 three state buffers.
Preferably, the alarm module includes buzzer.
The present invention has the following advantages that the advantage of the body temperature collection decorum of the invention is relative to prior art：Body
The features such as small, low cost of product, sensitivity high, short response time and strong antijamming capability, system thermometric stabilization, debugging side
Just, traditional mercury clinical thermometer can be replaced to detect body temperature.
When actual acquisition to human body temperature have the gap of ± 2 DEG C and range above with the fiducial temperature of setting when, this is
System can utilize the buzzer of warning device send alarm, and the attention of the person that causes thermometric judges that human body temperature is physiology factor
What change or extraneous error caused, then decide whether to carry out resurveying temperature.The system is in 30 DEG C~60 DEG C temperature ranges
It is interior, it is specific good linear, therefore the system being capable of precise acquisition temperature in 30 DEG C~60 DEG C temperature ranges.
Brief description of the drawings
Fig. 1 is a kind of structured flowchart of body temperature acquisition system of the invention.
In figure：1st, temperature signal collection module；2nd, signal amplification module；3rd, data conversion module；4th, controller module；5、
