Built-in aerial such as is automatically switched to positioned at indoor or urban area, imaging terminal, is advantageous to send and receive common indoor frequency
Segment signal（Such as 1800MHz, 2600MHz）.
Further, in one embodiment, as shown in figure 4, described Hall switch include Hall sensor Hall1 and
Hysteresis comparator COMP1；Hall sensor Hall1 input sensing external magnetic field strength, Hall sensor Hall1 output
End is connected with hysteresis comparator COMP1；Hysteresis comparator COMP1 output end output hall signal.Pass through the stagnant ring of reasonable set
Comparator COMP1 hysteresis band, the Hall voltage that hysteresis comparator COMP1 can be exported Hall sensor Hall 1 reach
To high level signal is just exported during a higher threshold value, can so avoid when camera is located in complex electromagnetic environment, by
Environmental magnetic field disturbs the false triggering for causing the first Hall switch.
And further, in the present embodiment, described Hall switch also includes time delay module TD and and gate circuit
AND2；Time delay module TD input and received from hysteresis comparator COMP1's with gate circuit AND2 first input end
The hall signal of output end output, time delay module TD output end are connected with the second input with gate circuit AND2, with door electricity
The hall signal of road AND2 output end output after treatment.By reasonable set TD delay time, first can be made suddenly
Your switch has the ability of anti-moment high-intensity magnetic field interference with the second Hall switch.
Further, in another embodiment, as shown in figure 5, described Hall switch includes Hall sensor battle array
Row；Described Hall sensor array includes three Hall sensors Hall1, Hall2 and Hall3, Hall sensor Hall1,
Hall2 and Hall3 output end is connected with three hysteresis comparators COMP1, COMP2 and COMP3 respectively, hysteresis comparator
COMP1 output end is connected with phase inverter INV, and phase inverter INV output end is connected with gate circuit AND1 first input end,
Hysteresis comparator COMP2 and COMP3 output end are connected with the second input and the 3rd input with gate circuit AND1 respectively,
Hall signal is exported with gate circuit AND1 output end；Three hysteresis comparators COMP1, COMP2 and COMP3 stagnant loop voltag point
Wei not V1, V2 and V3.Three hysteresis comparators COMP1, COMP2 are different with COMP3 stagnant loop voltag width, in diagram embodiment
In, V2>V1>V3；
Wherein, as shown in fig. 6, Hall sensor Hall1 and Hall3 are respectively in Hall sensor Hall2 both sides, accessing
Add-on accessories in field generating component induction zone produce magnetic field when, Hall sensor Hall2 is located at magnetic field center position,
Hall sensor Hall1 and Hall3 are located in same equipotential surface.
When it is high level that Add-on accessories magnetic field intensity, which is enough to make hysteresis comparator corresponding to Hall 2 to jump, it is necessary to make position
Hall voltage intensity could exist respectively between V1 and V3 caused by magnetic equipotential face at the Hall 1 and Hall 3
Low level is triggered on COMP1, high level is triggered on COMP3.So that AND1 exports high level.So, even if imaging terminal is set to
Near other kicker magnets, because other kicker magnets are difficult to form satisfactory magnetic equipotential face at Hall 1 and Hall 3,
Therefore imaging terminal will not also be mistakenly considered Add-on accessories access, further increase antijamming capability.
Described above is only preferred embodiment of the present utility model, it should be understood that the utility model is not limited to herein
Disclosed form, the exclusion to other embodiment is not to be taken as, and can be used for various other combinations, modification and environment, and
It can be modified in contemplated scope described herein by the technology or knowledge of above-mentioned teaching or association area.And this area
The change and change that personnel are carried out do not depart from spirit and scope of the present utility model, then all should be in right appended by the utility model
It is required that protection domain in.
The scope is overlapping compared with the magnetic cell-phone cover in technology.
