Abstract
The utility model discloses an output/measurement dual-purpose signal generator, which is mainly formed in a mode that firstly a singlechip is arrange in an integrated insulation box, then a nixie tube, arotating potentiometer and a diode are connected in the integrated insulation box by leads of an integrated printed circuit board and simultaneously the integrated insulation box is connected with a functional indicating lamp and an output port in a panel structure diagram and press keys into the whole body. When in use, the output/measurement dual-purpose signal generator is connected in a test circuit, not only can generate a stable frequency signal, but also can measure the frequency signal and has double functions. The output/measurement dual-purpose signal generator widely and sufficiently utilizes resources in the automation production application field and has two functions. The precision reaches 0.001Hz, the frequency measurement and output range is between 1.000 and 99.999Hz, the minimum variation quantity of the output frequency is 0.001Hz and the maximum variation quantity of the output frequency is 9.999Hz.
Description
Affiliated technical field
The utility model relates to a kind of signal generator, and particularly a kind of output/measurement dual-purpose type signal generator is suitable for the purpose of dual-use, and is of many uses in the automated production application.
Background technology
At present, the applied signal generator in instrument and meter for automation field is the independent output frequency signal that has, and needs special-purpose frequency measuring device when the measuring frequency signal.This has just wasted resource greatly, does not reach the purpose that makes full use of each instrument and meter.In addition precision low, read observing and controlling numerical value difficulty, inaccurate, complicated operation, also be the shortcoming that present signal generator had.
Summary of the invention
Problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of output/measurement dual-purpose type signal generator is provided.This generator is not only reasonable in design, makes simply, and inner to adopt single-chip microcomputer be core, by the LED charactron, and the LED single color LED, button and rotating potentiometer constitute man-machine interface, the precision height, function is strong, the reliability height, easy to operate, volume is little.
The technical solution adopted in the utility model is: in the insulation booth that is made into one, single-chip microcomputer at first is installed, lead by IC printed board connects charactron, rotating potentiometer, diode then, simultaneously, with functional indicator light, output port in the panel, button assembles and constitutes.During use, the utility model is connected in the measurement circuit, operates corresponding selection key, both can produce stable frequency signal, but measuring frequency signal again has double effects.Extensively made full use of resource in the automated production application, dual-use, precision reaches 0.001Hz, and frequency measurement and output area are 1.000-99.999Hz, and output frequency minimum change amount is 0.001Hz, and maximum change amount is 9.999Hz.
The beneficial effects of the utility model are, and are simple in structure, easy to use, with the single-chip microcomputer is core, by the LED charactron, and the LED single color LED, button and rotating potentiometer constitute man-machine interface, have the stable frequency signal of output, the dual-use function of accurate measuring frequency signal.Display precision improves, and novel watchdog circuit does not crash; Fault alarm shows error message when input signal is incorrect; Adopt normal structure, mould the shell face shield, both artistic and practical; Extremely low power consumption, long service life, input/output signal all adopts photoelectricity to isolate, and is furnished with watchdog circuit, system's strong interference immunity.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a panel construction schematic diagram of the present utility model.
Fig. 2 is a circuit theory schematic diagram of the present utility model.
Accompanying drawing number is: 1. charactron, 2. functional indicator light, 3. rotating potentiometer, 4. output port, 5. insulation booth, 6. button, 7. single-chip microcomputer, 8. diode, 9. lead.
Embodiment
With reference to Fig. 1, Fig. 2, in the insulation booth that is made into one (5), single-chip microcomputer (7) at first is installed, lead (9) by IC printed board connects (8) 3 of (1) 4 of charactrons, rotating potentiometer (3), diode then, simultaneously, with functional indicator light (2), output port (4) in the panel construction schematic diagram, button (6) assembles and constitutes.During use, the utility model is connected in the measurement circuit, operates corresponding selection key, both can produce stable frequency signal, but measuring frequency signal again has double effects.Extensively made full use of resource in the automated production application, dual-use, precision reaches 0.001Hz, and frequency measurement and output area are 1.000-99.999Hz, and output frequency minimum change amount is 0.001Hz, and maximum change amount is 9.999Hz.
