Embodiment
Please refer to Fig. 1, it illustrates the schematic diagram according to a kind of static guiding system 1 of this novel preferred embodiment.Static guiding system 1 comprises: static bracelet 10, static let-off gear(stand) 12 and arrangement for detecting 14.Static bracelet 10 is in order to wear the wrist (not illustrating) in the user, to receive static 11.Static let-off gear(stand) 12 is electrically connected in earthing potential GND.Because human body is conductor, therefore easily static is conducted on the material that human body touches by human body.On the product line as factory, such effect causes the infringement of electronic product easily, therefore need wear static bracelet 10 on promptly above-mentioned user's the wrist to be directed at earthing potential GND the staff.Arrangement for detecting 14 comprises: first oscillating circuit 140, first circuit for detecting 141, the first cresset module 142, resistance 143, second oscillating circuit 144, second circuit for detecting 145 and the second cresset module 146.First oscillating circuit 140 is electrically connected in static bracelet 10, produces first signal 131 when static bracelet 10 is normally worn wrist in the user.First circuit for detecting 141 changes 133 in order to detect first of first signal 131, and judgement static bracelet 10 is not normally worn.Among one embodiment, when normally wearing, first signal 131 is essentially the signal that an amplitude is little, frequency is little.Yet when static bracelet 10 is not normally worn, will cause the oscillating condition of first oscillating circuit 140 change, and then first frequency of oscillation of first signal 131 and first amplitude are increased and produce first and change 133.The first cresset module 142 will change 133 according to first and produce first cresset 135, and prompting static bracelet 10 is not normally worn.Cresset can be shown by the lamp of two different colours in an embodiment, for instance, shows with red light and green light.When wearing just often, show green light and red light is extinguished, and when normally not wearing, first cresset 135 shows with red light and green light is extinguished.
Fig. 2 illustrates among this novel embodiment, first circuit for detecting, the 141 more detailed circuit diagrams of static guiding system 1.It is noted that the circuit execution mode that this is novel can reach identical effect via other circuit design mode, is not limit by the circuit of present embodiment.Aforesaid first oscillating circuit 140 is one to have the circuit of the mechanism of feedbacking, and with under different oscillating conditions, exports first signal 131.And first circuit for detecting 141 comprises first high pass filter 20 and the first amplitude detector 22, and wherein first high pass filter 20 passes through high-frequency signal, and the low-frequency signal of filtering.Therefore, when static bracelet 10 is normally worn,, therefore will can not pass through high pass filter 20, and when static bracelet 10 is not normally worn, first frequency of oscillation will increase, and first signal 131 is passed through because first frequency of oscillation still is a low frequency.Please be the oscillogram of this first novel signal 131 simultaneously with reference to Fig. 3, wherein transverse axis is represented the time, and the longitudinal axis is represented amplitude.When static bracelet 10 was not normally worn, first frequency of oscillation and first amplitude will because frequency and amplitude value are all big, therefore can be detected as left half-wave type 30 easily by 20 of high pass filters.And when static bracelet 10 was normally worn, shown in right half-wave shape 31, first frequency of oscillation and first amplitude were all little, and will can not pass through high pass filter 20.And the first amplitude detector 22 comprises resistance 220, electric capacity 222 and comparator 224 in present embodiment.When static bracelet 10 is normally worn, will can't pass through first high pass filter 20 because of first signal 131, and resistance 220, electric capacity 222 not impacted.Therefore comparator 224 is not exported any signal.When static bracelet 10 is not normally worn, resistance 220 and electric capacity 222 receive first signal 131 from high pass filter 20, because first amplitude increases, therefore resistance 220 and electric capacity 222 will be greater than the reference signals 221 of comparator 224 after electric charge is accumulated, and then with first change 133, be substantial one first cue 223, export the first cresset module 142 to.The first cresset module promptly produces first cresset 135 according to first cue 223, and prompting static bracelet 10 is not normally worn.On the other hand, the circuit of second oscillating circuit 144, second circuit for detecting 145 and the second cresset module 146 also can adopt above-mentioned design to be achieved, so do not repeat them here.
By above-mentioned novel preferred embodiment as can be known, use this novel advantage and be amplitude and frequency by the signal of exporting according to the oscillating condition of oscillating circuit, detect easily the static bracelet wear and whether static is derived the path and is connected normally.
Though this is novel with the execution mode exposure as above; right its is not novel in order to limit this, anyly has the knack of this skill person, in not breaking away from these novel spirit and scope; when being used for a variety of modifications and variations, therefore this novel protection range is as the criterion when looking accompanying the claim person of defining.
