Fig. 2 is the structural representation of ray emission module in the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Door-locking system based on low emission source as illustrated in figs. 1 and 2, comprises key part and door lock section.Described key part comprises ray emission module 1, for launching gamma-rays.Described door lock section comprises X-ray detection X module 2, signal screening judge module 3 and electric control lock module 4.X-ray detection X module 2 is for detecting gamma-rays and amplifying after being converted to the signal of telecommunication.Whether signal screening judge module 3 meets default energy and quantity for the energy and quantity judging the described signal of telecommunication, if do not meet, is then failure to actuate, if meet, then sends control signal of unblanking; This signal screening judge module 3 is electrically connected with X-ray detection X module 2.Electric control lock module 4 carries out unlock operation based on described control signal of unblanking, and this electric control lock module 4 is electrically connected with signal screening judge module 3.Power module 6 is electrically connected with X-ray detection X module 2, signal screening judge module 3 and electric control lock module 4 respectively, is each module for power supply.
As shown in Figure 2, ray emission module 1 comprises housing and is placed on the radioactive source 1b in housing, and this radioactive source 1b adopts 137Cs.Owing to there is no Ce 137 in environment, the gamma-rays of identical energy can not be sent, so can not by false triggering; Only have particular source production unit just can make associated key, so can not be replicated.The quantity in required source is considerably less in addition, only needs nanogram (10 -9gram) to microgram (10 -6gram) source of magnitude, the gamma-ray energy launched is 0.6616MeV, the former intensity lower than five class sources, its radioactive intensity and environmental exact details similar, so on environment and key owner without any impact and injury.And the outside of radioactive source is covered with containment vessel (i.e. housing), safety, small volume and less weight, to be easy to carry.Gamma-rays through can not off-energy during material, so the security protection of door lock section can not affect the reception of signal.Do not need charging, can not by extraneous strong, weak electricity influence of magnetic field, can not by extraneous other physics and chemistry factor affect.Because the life-span of this radioactive source is long, its half-life is more than 20 year, thus the unit interval in release gamma-rays quantity and energy substantially constant.
As shown in Figure 2, housing comprises main casing 1a and is fastened on the lid 1c on main casing 1a, and this main casing 1a and lid 1c includes metal shell and is arranged on the lining with lead of inside of metal outershell, and lining with lead plays the effect of shielding.When needs are unblanked, open lid 1c, and the radioactive source 1b in ray emission module 1 is aimed at X-ray detection X module 2.When not unblanking, lid 1c is fastened on main casing 1a.
As shown in Figure 1, X-ray detection X module 2 comprises Nall crystal 2a and optical diode 2b, gamma-rays incides after in NaIl crystal, cause that Nall crystal 2a excites, de excitation, launch fluorescent photon, fluorescent photon enters optical diode 2b, after optical diode 2b collects, be converted to the signal of telecommunication be directly proportional to the energy of γ ray size of incidence.
As shown in Figure 1, described signal screening judge module 3 comprise signal screening submodule 3a and counting judge submodule 3b.Signal screening submodule 3a is for judging that the amplitude of the described signal of telecommunication is whether within the scope of predetermined amplitude, if not, is then failure to actuate; If so, then export the logic pulse signal of a standard, this signal screening submodule 3a is electrically connected with X-ray detection X module 2.Counting judges that submodule 3b is for judging that the quantity of the logic pulse signal that described signal screening submodule 3a sends within the unit interval is whether within the scope of predetermined number, if not, is then failure to actuate; In this way, then send control signal of unblanking, this counting judges that submodule 3b is connected with signal screening submodule 3a.Signal screening judge module 3 only counts Ce 137 full energy peak and judges, because in environment there there is no other radioactivity near this energy, so environment can not cause interference, the judgement of counting rate to judgement, also can prevent other unique people from utilizing hot to attempt.
As shown in Figure 1, electric control lock module 4 is the mechanical lock of Control, is arranged on door, for pinning door.After a number examination judge module sends control signal of unblanking, the actuating of relay opens mechanical lock automatically.
As shown in Figure 1, also comprise alarm module 5, this alarm module 5 is electrically connected with signal screening judge module 3, when signal screening judge module 3 judges that the energy of the ray that described X-ray detection X module 2 receives and discrepancy of quantity close the energy and quantity preset, when abnormal conditions namely being detected, then control alarm module 5 and send warning.
X-ray detection X module 2 and signal screening judge module 3 are installed in the inner side of door by the present invention, with the external world without any contacting, can not mechanical damage be subject to, and from the position be locked in door cannot be known outdoors, eliminate the possibility by mechanical device violence damage such as drill bits.In addition, latch portion, without keyhole, is not locked by artificial malice violence damage or the situation blocking keyhole so there will not be because opening.By the outer field metal protection of door to alpha ray and Beta-ray shielding, only have gamma-rays to enter, do not have other signals to affect ray detecting module 2.Extraneous highfield or the change of high-intensity magnetic field can not affect door lock section action.
Described in the present invention, radioactive source also can be 60Co, or is 133Ba, or is 207Bi, or is 152Eu.
