The temperature sensor of this temperature-sensitive sticker 31 also can be the IC wafer of a conformability again, temperature control IC as shown in Figure 4, and under fixed-bias transistor circuit, the temperature variation that temperature-sensitive sticker senses is directly changed into the period signal output of different frequency.
This thermometry module 34 receives from the period signal of each temperature-sensitive sticker of temperature-sensitive sticker 31 and measures its frequency, builds the table of comparisons in the warp and finds its corresponding temperature value, and send this database analytic unit 2 back to through computer standard interface.
The frequency method for measurement of this thermometry module 34 has three again:
One of which, as shown in Figure 5, be single period frequency principle of measurement schematic representation; Tin in a complete cycle of input signal, the times N r that the upper limb of counting reference signal climbs, the cycle T in that then can calculate input signal is:
Tin＝Nr/fre，
Therefore, frequency f in to be measured can for:
fin＝fre/Nr，
Frequency f re=100MHz with reference signal is an example, and the periodic error of counting is Δ t=1/fre=10ns, measures error ratio and is not more than 1% if order frequency, and then the cycle of input signal should be greater than 1 μ s, that is the frequency of signal to be measured should be less than 1MHz.
Its two, as shown in Figure 6, be multicycle frequency measurement principle schematic; In Nin complete cycle of input signal, the times N r that counting reference signal upper limb climbs, the cycle T in that then can calculate input signal is:
Tin＝Nr/Nin*fre，
Therefore frequency f in to be measured can for:
fin＝Nin*fre/Nr，
The periodic error of counting will be reduced to 1/Nin this moment, and therefore the frequency of maximum signal to be measured can be increased to Nin doubly.
Its three, as shown in Figure 7 for the time that unified frequency each time measures, be timing frequency principle of measurement schematic representation; As if setting the measurement time is 1 second, then counts reference signal pulse wave upper limb and triggers in fre time, and the times N in that input signal pulse wave upper limb takes place is the frequency of input signal, and frequency measurement this moment resolution is 1Hz; If will measure time decreased and be set at 0.1 second for 10 times, then frequency measurement resolution falls 10 times and be 10Hz.Therefore, can be according to the frequency range of input signal, coordinate frequency measures resolution and measurement time.
The foregoing description and graphic and non-limiting product form of the present invention and style, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from patent category of the present invention to its suitable variation or modification of doing.
