Description
Technical field
The utility model belongs to physical measurement field, relates to a kind of damped vibration curve measurement mechanism.
Background technology
One chip microcomputer is called for short single-chip microcomputer, is typical embedded microcontroller (Microcontroller Unit), and the abbreviation MCU of conventional English alphabet represents single-chip microcomputer, and it is be used in industrial control field the earliest.Current single-chip microcomputer penetrates into the every field of our life, is almost difficult to find which field not have the trace of single-chip microcomputer.Single-chip microcomputer runs by program, and can revise.Realize different functions by different programs, by program, with single-chip microcomputer can control LED easily, charactron lights speed and the rotating speed of motor, various random digit can be produced easily and to go forward side by side row operation.The high intelligence of product can be realized, high-level efficiency, and high reliability by program.
12864 liquid crystal display are that the dot matrix number of 128*64 lattice lcd module is called for short.The screen display advantage of lower cost of this dot matrix, is applicable to each quasi-instrument, the display field of mini-plant.
Summary of the invention
When the measurement of conventional damper oscillating curve, high tension spark generator need be used, experiment curv is recorded on recording chart, measuring accuracy is poor, draw also cumbersome, the purpose of this utility model is to design that a kind of structure is simple, easy to use, dependable performance, cheap damped vibration curve measurement mechanism, uses the voltage signal on resistance wire to carry out the Oscillation Amplitude of Damping vibration, automatically can show damped vibration curve in 12864 liquid crystal display.
For achieving the above object, the utility model comprises: air track (1), resistance wire (2), slide block (3), copper post (4), spring (5), first wire (6), second wire (7), privates (8), power supply (9), single-chip microcomputer (10), 12864 liquid crystal display (11), it is characterized in that: the length of air track (1) and resistance wire (2) is equal, resistance wire (2) is embedded in above air track (1), slide block (3) is placed on air track (1) and above also can horizontally slips on air track (1), slide block (3) central authorities are equipped with a cylindrical bore, copper post (4) embeds in slide block (3) cylindrical bore, the lower end of copper post (4) and resistance wire (2) close contact, spring (5) has two, spring (5) one end is fixed on the left side of slide block (3), the other end is fixed on the left side of air track (1), another root spring (5) one end is fixed on the right side of slide block (3), the other end is fixed on the right side of air track (1), the second wire (7) is drawn in copper post (4) upper end, the first wire (6) and privates (8) is drawn from the two ends of resistance wire (2), the positive pole of power supply (9) and negative pole connect the first wire (6) and privates (8) respectively, the voltage signal at the first wire (6) and the second wire (7) two ends sends into single-chip microcomputer (10), result is sent into 12864 liquid crystal display (11) display by single-chip microcomputer (10).
