Abstract
The utility model relates to an intelligent optical fiber sealing tape which comprises an original signal module, a transmitting terminal module, a receiving terminal module, a signal comparison module and a warning device; the transmitting terminal module comprises a signal modulation module and a light emitting device connected with the signal modulation module; the receiving terminal module comprises a light receiving device and a signal demodulation module connected with the light receiving device; the light emitting device is connected with the light receiving device through an optical fiber; the signal modulation module is connected at one end of the original signal module and the signal comparison module is connected at the other end of the original signal module; and the signal demodulation module is connected with the signal comparison module and the signal comparison module is connected with the warning device. The utility model adopts the light signal as the detection signal inside the sealing tape and utilizes the optical fiber or the photosensitive material as the signal transmission medium; and since the cost of the on-line bypass and the dummy signal deception to the optical signal is very high at present, the validity of the sealing tape is ensured.
Description
[technical field]
The utility model relates to the strip of paper used for sealing technical field, specifically is meant a kind of intelligent optical fiber strip of paper used for sealing.
[background technology]
There are some things need keep uninvaded state, for example, are temporary in the counter of customs in a period of time.For reaching this purpose, that uses at present mainly contains two kinds of methods, and a kind of is outsidely additionally to have the mechanical type strip of paper used for sealing of identification code to seal counter, and a kind of is to adopt e-seals.
The mechanical type strip of paper used for sealing need spend great amount of manpower and time, could discern and manage according to identification code.And this identification code is exposed outside, and some people that have an ulterior motive can duplicate the mechanical type strip of paper used for sealing with same identification sign indicating number and replace ruined former mechanical type strip of paper used for sealing.Therefore, the security of this mechanical type strip of paper used for sealing is very low.
General e-seals all adopts electric signal as the built-in detection signal of strip of paper used for sealing, because electric signal is insensitive to bypass, is easy to use various electronics bypasses and glitch technology fraud detection end, makes e-seals ineffective.Therefore, the security of e-seals also is lower.
[summary of the invention]
Technical problem to be solved in the utility model is to provide a kind of safe intelligent optical fiber strip of paper used for sealing.
The utility model is for solving the problems of the technologies described above by the following technical solutions:
A kind of intelligent optical fiber strip of paper used for sealing comprises former signaling module, transmitting terminal module, receiving end module, signal comparison module, the alarm established;
Wherein, the transmitting terminal module comprises signal modulation module, connected light emitting devices; The receiving end module comprises light receiving element, connected signal demodulation module;
Be connected by optical fiber between light emitting devices and the light receiving element;
Former signaling module one end of establishing connects the signal modulation module, and the other end connects the signal comparison module;
The signal demodulation module connects the signal comparison module, and the signal comparison module also connects alarm.
In the utility model, the original start signal is modulated to light emitting devices by signal, and light signal is by Optical Fiber Transmission, and optical fiber seals protected object as strip of paper used for sealing, and light signal is by light receiving element and signal demodulation and the comparison of former setting signal.Signal by optical fiber under the normal condition is constant, and the signal that receiving end receives is identical with former setting signal.When light path destroyed, as strip of paper used for sealing be unlocked, transmitting terminal or receiving end module are destroyed etc., the signal that receives is different with former setting signal, the signal comparison module provides alerting signal.Thereby reach the purpose of protection object.
The utility model adopts light signal as the built-in detection signal of strip of paper used for sealing, uses optical fiber or light-guide material as signal transmission medium.Because the cost that the online bypass and the glitch of light signal are cheated is very high at present, guaranteed the validity of strip of paper used for sealing.Advantage of the present utility model is: intelligent optical fiber strip of paper used for sealing is safe.
[description of drawings]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is a theory diagram of the present utility model.
[embodiment]
See also shown in Figure 1ly, a kind of intelligent optical fiber strip of paper used for sealing comprises former signaling module 10, transmitting terminal module 20, receiving end module 30, signal comparison module 40, the alarm 50 established.
Be connected by optical fiber 60 between light emitting devices 22 and the light receiving element 31.
The former original start signal of establishing in the signaling module 10 arrives light emitting devices 22 by signal modulation module 21; light signal is by optical fiber 60 transmission; optical fiber 60 seals protected object 70 as strip of paper used for sealing, and light signal compares with former setting signal by light receiving element 31 and signal demodulation module 32.Signal by optical fiber under the normal condition is constant, and the signal that receiving end receives is identical with former setting signal.When light path destroyed, as strip of paper used for sealing be unlocked, transmitting terminal module 20 or receiving end module 30 are destroyed etc., the signal that receives is different with former setting signal, signal comparison module 40 transmits alerting signals and provides alerting signal to alarm 50.Thereby reach the purpose of protection object.
The utility model adopts light signal as the built-in detection signal of strip of paper used for sealing, uses optical fiber or light-guide material as signal transmission medium.Because the cost that the online bypass and the glitch of light signal are cheated is very high at present, guaranteed the validity of strip of paper used for sealing.Advantage of the present utility model is: intelligent optical fiber strip of paper used for sealing is safe.
