Abstract
The utility model relates to a timer, specifically to a counter-based timer. The timer comprises an electrical equipment drive circuit, a power supply, a time-based signal circuit, a counter and a delay setting button, wherein the time-based signal circuit is connected to the counter, the delay setting button and the electrical equipment drive circuit, respectively; the counter is connected to the delay setting circuit, the power supply and the electrical equipment drive circuit, respectively; and the counter is a 16-bit counter. The counter-based timer provided by the utility model has the advantages that the time precision is high by using a counter, the delaying time is long and the reliability is high.
Description
Technical field
The utility model relates to a kind of timer, particularly a kind of timer based on counter.
Background technology
Timer has a wide range of applications in electrical equipment control.To obtain long time-delay at traditional RC timer, not only need high capacity, capacitor that leakage current is little, and timing accuracy be low, be difficult to the progress of Displaying timer.
Summary of the invention
The purpose of this utility model provides a kind of timer based on counter.This timer adopts high precision heuristicimal counter, thereby it is low to efficiently solve current timer timing accuracy, is difficult to the problem of the progress of Displaying timer.
This timer, comprise electrical apparatus driving circuit, power supply, time-base signal circuit, counter, delay adjustments button, wherein the time-base signal circuit links to each other with counter, delay adjustments button, electrical apparatus driving circuit respectively, counter is connected with delay setting circuit, power supply, electrical apparatus driving circuit respectively, wherein the sixteen bit counter of counter employing.
Thereby this timer adopts counter to have the time precision height, the long and high beneficial effect of reliability of delay time.
Description of drawings
Fig. 1 is this schematic diagram based on the timer of counter
Embodiment
As shown in Figure 1, should comprise time-base signal circuit, counter, power supply, delay adjustments button, electrical apparatus driving circuit based on the timer of counter, the time-base signal circuit links to each other with counter, delay adjustments button, electrical apparatus driving circuit respectively, thereby for three unit provide effective time-base signal, counter is connected with delay setting circuit, power supply, electrical apparatus driving circuit respectively.Its principle of work is that power supply is powered to counter, carry out the setting of time by the delay adjustments button, and with the time-delay signal send counter to, provide corresponding time-base signal by the time-base signal circuit for counter, LED display driver circuit, thereby counter is realized the precise time control of electrical equipment according to the setting of time.Counter can adopt the sixteen bit counter of pinpoint accuracy.
Although the utility model here specifically describes in conjunction with the specific embodiments, but be understandable that this is illustration rather than restriction, under the prerequisite of the spirit of the present invention that does not break away from accessory claim and limited, in the scope of and accompanying drawing disclosed at preamble, it all is possible reasonably changing and revising.
