Any and all combinations.
Referring to Fig. 1, the booting encryption device 100 that the utility model first embodiment proposes, is applied in electronic equipment,
The booting encryption device 100 include controller 10, the keyhole 20 on the electronic equipment and with the keyhole
20 matched keys 30.
The key 30 is equipped with filter layer 303, specifically, the filter layer 303 is set to 30 outer layer of key.It is described
Filter layer 303 is for example, by using polycarbonate.
The inside of the keyhole 20 is respectively equipped with the infrared transmitting tube 40 and infrared receiving tube 50 for corresponding to each other setting, tool
Body, the infrared transmitting tube 40 and the infrared receiving tube 50 can be arranged with face.
The infrared receiving tube 50 is used to receive the infrared signal that the infrared transmitting tube 40 emits, and red by what is received
The infrared intensity of external signal is sent to the controller 10；
The controller 10 is electrically connected with the infrared receiving tube 50, and the controller 10 is for receiving described infrared connect
The infrared intensity that closed tube 50 sends over, and change determining the infrared intensity that the infrared receiving tube 50 sends over
When, starting-up signal is issued to the electronic equipment.
Referring to Fig. 2, in one example, the controller 10 may include receiving module 101, comparison module 102, hair
Module 103 and memory 104 are sent, the threshold value is stored in the memory 104；
The receiving module 101 is for receiving the infrared intensity that the infrared receiving tube 50 sends over；
In the infrared intensity and the memory 104 that the comparison module 102 is used to receive the receiving module 101
The threshold value of storage compares；
The sending module 103 be used for the comparison module 102 determine the receiving module 101 receive it is infrared
When intensity is less than the threshold value stored in the memory 104, starting-up signal is issued to the electronic equipment.
After the key 30 is inserted into the keyhole 20, the filter layer 303 is for blocking the infrared emission
The infrared light that pipe 40 issues.
In one example, the controller 10 can use MCU.And it is pointed out that controller 10 can be used
The managing chip carried in electronic equipment, the power supply of controller 10, infrared transmitting tube 40 and infrared receiving tube 50 can be used
The power supply carried in electronic equipment is powered, therefore for electronic equipment, without increasing excessive cost.Specifically, infrared
The infrared signal that reception pipe 50 receives needs first to be converted to electric signal, then electric signal transmission is accordingly divided to controller 10
Analysis, processing, the corresponding electric signal of the infrared light of varying strength is different, further, it is also possible to by AGC (automatic growth control) skill
Art is carried out gain to electric signal, is exported with this level for obtaining standard to controller 10.
In the specific implementation, a threshold value can be stored in the memory 104 of controller 10 in advance, it is possible to understand that,
The threshold value stored in the memory 104 can be configured according to coverage extent of the filter layer 303 to infrared light, and key is worked as in guarantee
After spoon 30 is inserted into keyholes 20, the infrared light blocked through filter layer 303 that infrared receiving tube 50 receives it is infrared strong
Degree can be less than threshold value.
In the case where keyhole 20 is not inserted into key 30, the infrared signal that infrared transmitting tube 40 emits is connect by infrared completely
Closed tube 50 receives, and the infrared signal that infrared receiving tube 50 receives is first converted to electric signal, is then sent to MCU, and MCU will
The electric signal determines the electric signal greater than threshold value, then will not issue starting-up signal to electronic equipment compared with threshold value.And in key
In the case that keyhole 20 is inserted into key 30, the infrared signal that infrared transmitting tube 40 emits is blocked by the filter layer 301 on key 30,
The strength reduction for the infrared signal for causing infrared receiving tube 50 to receive, the low intensive infrared signal of the drop are converted into electric signal
After be sent to MCU, the electric signal received compared with threshold value, is determined the electric signal received and is less than threshold value, then at this time by MCU
Starting-up signal can be issued to electronic equipment, electronic equipment is made to be switched on.
As a specific example, in the present embodiment, the keyhole 20 can be in rectangle, and the key 30 includes key
First 301, the shank of the key 302, the key bit 301 is in rectangle, and the key bit 301 is matched with the size of the keyhole 20,
So that key bit 301 is inserted into keyhole 20.The filter layer 303 is set to the outer layer of the key bit 301.
In addition, the controller 10 can be also used for receiving described red in order to further enhance the uniqueness of booting permission
The infrared intensity that outer reception pipe sends over, and when determining the infrared intensity received equal to a certain specific threshold value, just to
The electronic equipment issues starting-up signal.Specific threshold value needs are configured according to filter layer 303, filter layer 303
Structure (including material composition, coverage area of filter layer 303 etc.) only corresponds to a threshold value.In this way, when key 30 is inserted into key
After in hole 20, the infrared intensity of the infrared light blocked through filter layer 303 only received in infrared receiving tube 50 can
Just it is equal to the specific threshold value, controller 10 just can issue starting-up signal to electronic equipment.This is to be applied to other to have
After in the object insertion keyhole 20 of filter effect, since the shading of the filter layer 303 on its shaded effect and key 30 is imitated
Fruit is different, therefore, it is impossible to realize booting, has safer booting permission.
According to booting encryption device provided in this embodiment, separation design, key are used to the booting of electronic equipment
It can be taken care of by administrator, play the role of the permission control that is switched on, only when key is inserted into keyhole, filter layer on the key
Infrared blocking to infrared transmitting tube transmitting, finally makes the received infrared intensity of controller be less than or equal to threshold value, by controlling
Device processed issues starting-up signal to electronic equipment, so that electronic equipment is switched on, especially suitable for the interactive intelligence used in public
Plate class of electronic devices.
Another embodiment of the utility model also provides a kind of electronic equipment using above-mentioned booting encryption device 100, the electricity
Sub- equipment is, for example, intelligent interaction plate.
Referring to Fig. 3, the booting encryption device 100a that the utility model second embodiment proposes, is applied to electronic equipment
In, the present embodiment is improved on the basis of first embodiment, and in the present embodiment, the booting encryption device 100a is also wrapped
Alarm 60 is included, the alarm 60 is electrically connected with the controller 10, and the alarm 60 can use combined aural and visual alarm.
In the specific implementation, alarm 60 may be mounted on the fuselage of electronic equipment.The controller 10 is also used to receiving
Infrared intensity is greater than threshold value, and while being less than initial value controls the alarm 60 and issues alarm, and the initial value is the key
When being not inserted into the key 30 in hole 20, the infrared letter for the transmitting of the infrared transmitting tube 40 that the infrared receiving tube 50 receives
Number signal strength.By increasing alarm 60, improper booting can be prompted.For example, someone uses the rod
Object is inserted into keyhole 20, since, not for blocking the filter layer of infrared light, but club itself also can on this kind of club
The infrared light of shield portions to a certain extent, therefore, in this case, controller 10 will call the police device 60 and issue instruction, make
Alarm 60 is alarmed, and reminds administrator's electronic equipment by improper booting, thus practicability and safety.
