Description
Technical field
The utility model relates to the circuit reset technical field, particularly a kind of device of noncontact circuit reset.
Background technology
Present many electronic equipments all have been equipped with special reset key, are used for system and the external world under the abnormal conditions occur by the physical operations interfering system.Traditional resetting all is to be realized by the physics reset switch, physical switch is realized reset operation to system by the reset pin of direct control system, this simple to operate direct, but problem below existing: 1 because physical switch need allow the client operate, so on equipment, all will reserve special hole or button, open and use to the client.Certain difficulty is all caused to requirements such as the outward appearance of product and waterproof in these holes physically.2 because direct opening that reset given the external world, and anyone can reset to system by reset key, and certain potential safety hazard is arranged.
Summary of the invention
The purpose of this utility model provides a kind of noncontact circuit reset device, utilizes magnetic effect that system is carried out contactless resetting and can eliminate structure perforate problem, and the magnetic coding can guarantee that system can or not have operation owing to malice and causes the reset circuit false triggering.
The utility model adopts following scheme to realize: a kind of noncontact circuit reset device is characterized in that comprising:
N magnetic induction control logic device, this N magnetic induction control logic device formed NS utmost point induction lattice according to a precalculated position on a plane, and wherein N is a natural number;
One triggers dot matrix with the NS of described NS utmost point induction lattice identical topology, in order to trigger described NS utmost point induction lattice, controls described magnetic induction control logic device output triggering signal; And
One logic gates, described triggering signal forms a reset signal through this logic gates.
In the utility model one embodiment, described NS triggers dot matrix and is arranged on the carrier.
In the utility model one embodiment, it is to be embedded in the described carrier that described NS triggers dot matrix.
In the utility model one embodiment, it is that magnet or electromagnet by corresponding number constitutes that described NS triggers dot matrix.
In the utility model one embodiment, described magnetic induction control logic device is the magnetic logical circuit that hall device or tongue tube are formed.
In the utility model one embodiment, described N is 4.
The utility model is replaced by non-contacting magnetic induction triggering mode with traditional physics reset trigger switch, be about to reset trigger and be split as special-purpose magnetic trigger equipment and magnetic induction triggering two parts, trigger the contactless reset trigger of realization by the magnetic trigger equipment near magnetic induction, preventing aspect the false triggering, triggering is encoded to inner magnet, the external magnetic field that only meets coding requirement can excite the reset circuit action, coded system adopts the combination of magnetic pole diverse location to carry out, the position is consistent with the reset circuit of magnetic force authentication with magnetic pole, to satisfy the condition that resets that excites.The utility model is simple in structure, and cost is low, has good practical values.
Description of drawings
Fig. 1 is the corresponding schematic diagram of the utility model embodiment dot matrix.
Fig. 2 is the utility model embodiment device structural representation.
Fig. 3 is the utility model embodiment device physical circuit configuration diagram.
Wherein: 1 is carrier; 2,3,9 is magnet or electromagnet; 4,5,8 are magnetic induction control logic device; 6 are the reset signal input; 7 are reset signal output.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Present embodiment also provides a kind of noncontact circuit reset device, it is characterized in that comprising:
N magnetic induction control logic device, this N magnetic induction control logic device formed NS utmost point induction lattice according to a precalculated position on a plane, and wherein N is a natural number;
One triggers dot matrix with the NS of described NS utmost point induction lattice identical topology, in order to trigger described NS utmost point induction lattice, controls described magnetic induction control logic device output triggering signal; And
One logic gates, described triggering signal forms a reset signal through this logic gates.
Please continue with reference to Fig. 1, magnetically encoding is that three magnet or electromagnet constitute among the figure, wherein distinguishes the polarity of magnet 2,3 with oblique line.When this carrier places the top on plane, magnetic induction control logic device place, after the dot matrix correspondence, each magnetic induction control logic device is switched on, the output reset signal.What deserves to be mentioned is that in the present embodiment, described magnetically encoding is to be embedded in the described carrier.The moulding of this carrier can design according to actual needs, for example shape such as key or a strip lamellar body etc.It is that magnet or electromagnet by corresponding number constitutes that described NS triggers dot matrix.Because magnet has N, S polarity, therefore also different by the different magnetically encodings that is combined to form, please refer to Fig. 2 and Fig. 3, in the present embodiment, above-mentioned magnetic induction control logic device is 4, as shown in Figure 2.Guaranteed the fail safe of magnetically encoding like this.Described NS triggers the KEY that resets that forms a band magnetically encoding on a dot matrix setting and the carrier, and is preferable, and this NS triggers dot matrix and can be embedded on the described carrier, and the moulding of this carrier can design as mentioned above according to actual needs.
In the present embodiment, described magnetic induction control logic device can be the magnetic logical circuit that hall device or tongue tube are formed, owing to can not cause the triggering of system reset circuit after the partial logic unit of magnetic logical circuit is triggered by external interference magnetic field, have only whole magnetic logics to be triggered and just can cause the work of reset circuit.Therefore this triggering requires the external magnetic field to satisfy corresponding magnetic force on distribution, intensity, level property and triggers requirement, and fail safe is higher.
Please refer to Fig. 3, form the reset trigger circuit with 4 5711A magnetic induction hall devices and gate circuit in the present embodiment, when the carrier 1 that is provided with magnetically encoding during near circuits for triggering, 4 5711A are triggered low simultaneously, and logic gates will be exported the triggering signal of electronegative potential.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
