Detailed description of the invention
Fig. 1 is circuit structure schematic diagram of the invention.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings:
As shown in Figure 1: the present invention by battery E, first resistor R1, second resistance R2,3rd resistor R3, the 4th resistance R4,
Basis set when the 5th resistance R5, first capacitor C1, the second capacitor C2, third capacitor C3, the 4th capacitor C4, the 5th capacitor C5, first
It is formed at basis set when chip IC 1, second at chip IC 2, operational amplifier IC3 and voltmeter V, the battery E is 12V, described
First resistor R1 is 3.3k Ω, the second resistance R2 is 15k Ω, the 3rd resistor R3 is 3k Ω, the 4th resistance R4
For 2k Ω, the 5th resistance R5 be 56k Ω, the first capacitor C1 is 10uF, the second capacitor C2 is 1uF, described
Three capacitor C3 are 47uF, the 4th capacitor C4 is 0.01uF, the 5th capacitor C5 be 0.1uF, it is described first when basis set at
Chip IC 1 and it is described second when basis set at the model of chip IC 2 be NE555, the operational amplifier IC3 model LM741,
The voltmeter V is 0-10V voltmeter.
Working principle of the present invention is as follows:
In Fig. 1 first when basis set at chip IC 1 form multivibrator, frequency of oscillation is 60Hz or so, output
Basis set provides trigger pulse at chip IC 2 when pulse square wave signal is second, and basis set forms monostable electricity at chip IC 2 when second
Road, at first, basis set is exported at chip IC 1 under the triggering of pulse, and basis set is also at the toggle frequency of chip IC 2 when second
60Hz or so, after first resistor R1 resistance value determines, basis set depends on to be measured at the duty ratio of 2 output voltage of chip IC when second
The capacity of the capacity of tunnel lining-up structure C X, tunnel lining-up structure C X to be measured is bigger, then the duty ratio of output voltage is bigger, i.e., and
Basis set broadens at the voltage pulse that chip IC 2 exports when two, operational amplifier IC3 and its peripheral circuit composition filtering and voltage with
With circuit, wherein the 5th capacitor C5 is played a filtering role, output voltage U0 is equal to the voltage of operational amplifier IC3 third pin, it
Basis set exports average value of the pulse after capacitance-resistance filter, lining-up knot in tunnel to be measured in circuit of the present invention at chip IC 2 when being second
There is good linear relationship between structure CX and output voltage U0.The density of tunnel lining-up structure C X to be measured directly affects its capacitor
Capacitance, and by judging that the capacitance of capacitor judges the density of tunnel lining-up structure.
Basic principles and main features and advantages of the present invention of the invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
