The beneficial effects of the utility model are:
The utility model is a kind of electronic information anti-jamming circuit, compared with prior art, the utility model runs into strong jamming pulse signal, when deadlock phenomenon appears in analog chip, oscillating circuit is starting of oscillation immediately, exports the six pin reset terminal of a reset signal to single-chip microcomputer, when making anti-interference simulation by force, base chip is reworked, state before making mouse signal still can connect fault continues to run, and substantially increases the anti-interference of mouse, has the value applied.
Accompanying drawing explanation
Fig. 1 is circuit structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: the utility model comprises signal input circuit 1, current rectifying and wave filtering circuit 2, analog circuit 3, power supply 4 and signal output apparatus 5, described signal input circuit 1 is connected by the signal input part of described current rectifying and wave filtering circuit 2 with described analog circuit 3, the signal output part of described analog circuit 3 is connected with the input of described signal output apparatus 5, and described power supply 4 is connected with described signal input circuit 1, described current rectifying and wave filtering circuit 2, described analog circuit 3 and described signal output apparatus 5 simultaneously.
Particularly, described signal input circuit 1 is made up of the first resistance R1, the second resistance R2 and the 3rd electric capacity C3; Described current rectifying and wave filtering circuit 2 is made up of to the 4th diode VD4 the 3rd resistance R3, the 4th resistance R4, the second electric capacity C2, the second diode VD2; Described analog circuit 3 is made up of analog chip IC and the first electric capacity C1; Described signal output apparatus 5 is made up of the first diode VD1, the 5th resistance R5 and the 4th electric capacity C4.
Operation principle of the present utility model is as follows:
Second pin of analog chip IC and the 6th pin input signal, the 3rd pin are for output signal, the 4th and the 8th pin connects positive source, the first pin connects negative pole, the 7th pin is connect transistor discharge end in integrated circuit.Because the 7th pin and the 5th of analog chip IC is connected to the first electric capacity C1 between pin input end and negative pole, and the first electric capacity C1 is by the 7th pin discharge and recharge, its voltage levels constantly changes, 3rd pin and input just constitute a multivibrator circuit, and the 5th resistance R5 is feedback resistance.When normally working, the 3rd pin timing of analog chip IC sends pulse signal, and play clamping action by the 3rd diode VD3, oscillating circuit can not starting of oscillation.Once run into strong jamming pulse signal, when deadlock phenomenon appears in analog chip IC, oscillating circuit is starting of oscillation immediately, exports the six pin reset terminal of a reset signal to single-chip microcomputer, makes analog chip IC rework by force, thus reach jamproof effect.
Component parameter of the present utility model is selected as follows:
The diode that DC power supply is 5V, the model of analog chip IC is KA555, the first resistance R1 is 80 Ω, the second resistance R2 is 300 Ω, the 3rd resistance R3 is 400 Ω, the 4th resistance R4 is 1k Ω, the 5th resistance R5 is 5k Ω, the first electric capacity C1 is 200uf, the second electric capacity C2 is 360uf, the 3rd electric capacity C3 is 60uf, the 4th electric capacity C4 is 90uf, the first diode VD1 is model 70HF80 to the 4th diode VD4.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
