Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, and following examples are explanation of the invention and the present invention is not limited to following examples.
Embodiment 1:
Quiet time switch of a kind of knob and preparation method thereof, as shown in Figure 1, comprise shell (5), shell (5) top is provided with top cover (1), top cover (1) is provided with the rectangular opening (4) installing charactron, top cover (1) edge is provided with timing indication dial disc, outer casing bottom is provided with the base plate (6) of band wire guide, base plate (6) is provided with rotational potentiometer (3), described rotational potentiometer (3) is fixed by the potentiometer axis hole on top cover (1) and knob (2) machinery, and base plate (6) is provided with circuit board (7).
As shown in Figure 6, described circuit board 7 is provided with control module, control module connects digital pipe display circuit, rotational potentiometer 3, transistor amplifier or optocoupler or solid-state relay and power supply respectively, and transistor amplifier connects relay or optocoupler connects silicon controlled control circuit.
Principle of work: after powering on, if need to arrange timing, then only need clockwise or the knob be rotated counterclockwise on top cover, then coupled potentiometer output voltage changes, potential voltage collection is realized by A/D converter in AVR single chip ATMEGA16 sheet, the output voltage range of rotational potentiometer is between 0-5v, if gather gained voltage with the pass arranging timing be, timing range as requested, determine the value of coefficient k, wherein potentiometer adopts high-precision rotational potentiometer, get its rotating cycle corresponding minimum and maximum magnitude of voltage respectively as the parameter of minimum and maximum timing, meanwhile, single-chip computer control system will be shown on four seven segment digital tubes the result of Timing Processing, and synchronous averaging internal timing/counter T0 starts timing, after timing has arrived, single-chip microcomputer will send look-at-me, meanwhile call Interruption service routine, to single-chip microcomputer pd5 pin high level signal, trigger relay or controllable silicon or solid-state relay action, thus disconnecting consumers or access load, thus the power-off realized load and power on operation.
Tradition machinery relatively, quiet, accurate, reliable, timing range is wide, relatively current electric timing switch, reasonable in design, simple, adopt cylindrical rotary switch, meet for a long time people to the use habit of mechanical rotary switch, concerning each age level user, there is no study and be accustomed to the setting of electric timing switch and the requirement of operation steps, this time switch is without other additional functions, therefore whole panel designs is simple, without any button on top cover, only has one for the rectangular window of group of four figures pipe display, a knob is only had to carry out the time setting of completion timing switch, in use, may be used for household electrical appliance, the timing demands of commercial production and control, only need the rotation knob similar with mechanical timer can realize the setting of time, as long as gained voltage is gathered by comparison inner, just calculating gained timing can be gone out timing by the numeral method on top cover 1, and start timer.Simple to operate, cost is low, only needing clockwise or be rotated counterclockwise knob can completion timing operation, enormously simplify operation and the setting up procedure of electric timing switch, the efficiency that improve assembling, debugging and keep in repair; Whole circuit design is succinct, utilization carries acquisition function AVR single chip does not need extra ad acquisition chip, by software collection voltage, and determine timing value by comparing, and start timing, timing terminates, without the need to the timing knob that resets, to enormously simplify the complex structure degree of time switch design, improve Practical significance.Power unit, forgo traditional transformer, rectification, filtering, voltage stabilizing be separated 220v exchange turn 5v direct current design, adopt small size LD03-10B05R2(220VAC-5VDC) AC-DC power module, the very little 37.0*24.5*18.0(mm of its size), to greatly reduce the size of whole timer like this, line is simple simultaneously, for equipment and instrument, household electrical appliance, significant.
In addition, it should be noted that, the specific embodiment described in this instructions, the shape, institute's title of being named etc. of its parts and components can be different.All equivalences of doing according to structure, feature and the principle described in inventional idea of the present invention or simple change, be included in the protection domain of patent of the present invention.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment; only otherwise depart from structure of the present invention or surmount this scope as defined in the claims, protection scope of the present invention all should be belonged to.
