The beneficial effect that the technical scheme that the utility model provides is brought:
The anti-apparatus for removing of special-shaped bayonet socket of the present utility model, comprise: the radio frequency encoded tag judging the master control circuit board whether described bayonet socket is removed or changes and storage secret key, described bayonet socket is arranged on main body machine, it is inner that described master control circuit board is arranged on described main body machine, and it is inner that described radio frequency encoded tag is arranged on described bayonet socket; When special-shaped bayonet socket is replaced, main control circuit can detect in real time, prevents the illegal act of lawless person, improves the property safety of user.
Accompanying drawing explanation
Fig. 1 is the structural representation of the bayonet socket supervising device that the utility model provides.
Embodiment
Reference accompanying drawing also further illustrates the technical solution of the utility model by embodiment.
A kind of bayonet socket supervising device, comprise: the radio frequency encoded tag 02 judging the master control circuit board 01 whether described bayonet socket is removed or changes and store secret key, described bayonet socket 10 is arranged on main body machine 20, it is inner that described master control circuit board 01 is arranged on described main body machine 20, and it is inner that described radio frequency encoded tag 02 is arranged on described bayonet socket 10.
Master control circuit board 01 is by RFID near field wireless communication protocol or self-defined wireless communication protocol under normal circumstances, the key of the radio frequency encoded tag 02 of special-shaped bayonet socket 10 inside is read in timing, this key is the unique key that each machine produces at random or initiatively sets, be stored in master control circuit board 01 and radio frequency encoded tag 02 respectively according to self-defined mechanism, after master control circuit board 01 reads key success, carry out key authentication, the key that key value in the radio frequency encoded tag 02 read exactly and master control circuit board 01 store mates according to self-defined mode, after key match success, think normal condition, be left intact,
If bayonet socket 10 is illegally changed, the secret key that master control circuit board 01 obtains radio frequency encoded tag 02 is again mated, and is that master control circuit board 01 produces at random or uniquely sets owing to needing the default secret key of coupling, and the bayonet socket 10 of replacing is difficult to that the match is successful, if it fails to match, send alarm; Even if bayonet socket 10 is successfully changed by lawless person in the event of a power failure, new bayonet socket does not mate with the default secret key in master control circuit board due to its secret key carried, and will send alarm.
Master control circuit board 01 comprises the read module 011 reading described secret key, judge to send the first warning circuit 013 of the alerting signal that described bayonet socket is replaced when described key does not mate with the preset-key of described master control circuit board by the first judge module 012 whether described key and the preset-key of described master control circuit board 01 mate.
Master control circuit board 01 is less than or equal to predeterminable range threshold values with the distance of described radio frequency encoded tag 02.Radiofrequency signal is short range, wireless signals, needs signal sending end, i.e. radio frequency encoded tag 02 and signal receiving end, i.e. distance between the read module 011 of master control circuit board 01 is in certain scope, and preferably, above-mentioned predeterminable range threshold values is 20cm.
Also comprise: level setting circuit 03 and contact type connector 04, described level setting circuit 03 is arranged on the inside of described bayonet socket 10, one end of described contact type connector 04 is arranged on the installed surface contacted with described main body machine 20 of described bayonet socket 10, other end correspondence is arranged on described main body machine 20, one end of described contact type connector is connected with other end contact, described level setting circuit 03 is connected with one end of described contact type connector 04, and the other end of described contact type connector 04 is connected with described master control circuit board 01.
Described master control circuit board 01 also comprises the second judge module 014 judging whether described contact type connector normally connects and the second warning circuit 015 sending the alerting signal that described bayonet socket 10 is removed when described contact type connector 04 disconnects.
During normal connection, level setting circuit 03 is connected with master control circuit board by contact type connector, the signal input pin of main control circuit 01 is fixed on high level by pull-up resistor, when bayonet socket 10 is removed, two terminals of contact type connector are separated, level setting circuit 03 is removed simultaneously, the signal input pin that master control circuit board 01 is connected with contact type connector gets back to the low level state of acquiescence, and the second judge module 016 of master control circuit board 01 sends alarm according to the state change of this pin.
Status radio frequency encoded tag 02 and described level setting circuit 03 to stagger setting relative to described installed surface.
Radio frequency encoded tag 02 and level setting circuit 03 are installed in the plane parallel with installed surface, and the two staggers and arranges in order to avoid radiofrequency signal is hindered.
To sum up, the anti-apparatus for removing of special-shaped bayonet socket that the utility model provides, when special-shaped bayonet socket is illegally removed, the level setting circuit being arranged on special-shaped bayonet socket is ineffective, and the signal input pin of master control circuit board becomes low level by high level, sends alerting signal; When special-shaped bayonet socket is illegally changed, master control circuit board reads the secret key of special-shaped bayonet socket again, if cannot mate with the default secret key in master control board, sends alerting signal; Whether this device detects special-shaped bayonet socket in real time and is removed or changes, and prevents the illegal act of lawless person, improves the property safety of user.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; any people being familiar with this technology is in the technical scope disclosed by the utility model; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
