Background technology
At present in the police criminal detection process, and to collect various material evidences in various criminal, the civil case, mainly deliver to and identify office, it is identified or as material evidence from the scene of collecting.In the prior art, to the material evidence of collecting, in depositing or passing on, use paper spare or plastic or other material usually, not special-purpose sealing bag, easily material evidence is caused and lose, damage, wear and tear, pollute and destruction, be difficult for long preservation, thereby influence just, safety, the real effectiveness of case examination, so it is most important to keep properly material evidence.
Summary of the invention
The purpose of this utility model is, a kind of electronics Material evidence bag is provided, and it is easy to operate that it is had, and not influenced by objective factor such as artificial interferences, is convenient to check and preservation, the accurate safety of information.
The utility model to achieve these goals, following technical scheme is provided: it comprises bag, bag is provided with the radio influence electronic tag.Bag top is provided with a bag edge, and bag is provided with along the limit and is used for carrying out the leak free bonding strip with bag.Described electronic tag includes the micro chip and the antenna that can be excited and send to read-write equipment radiofrequency signal non-contactly by relevant radio frequency read-write equipment.
Electronic tag described in the utility model is being commonly called as of RFID, and RFID is the abbreviation of Radio Frequency Identification, and term is a RF identification.The electronic tag RF identification is a kind of contactless automatic identification technology, and it is by the automatic recognition objective object of radiofrequency signal and obtain related data, and identification work need not manual intervention, can work in various harsies environment.Electronic label technology can be discerned high-speed moving object and can discern a plurality of labels simultaneously, and swift and convenient to operate, it can discern single very concrete object, rather than can only discern a type objects as bar code; It adopts radio frequency, can see through exterior material and read data, and bar code must read information by laser; Can distinguish a plurality of objects simultaneously, and bar code can only be read singly, storage capacity is big; Can also not have the source remote distance read-write: maximum can reach 120CM; Safety is anti-collides: compare with bar code, need not adjusting to a line scanning, and read or write speed is fast, but identification in the multiple goal identification, motion, per second is discerned 30 at most.Long service life: do not have the machinery wearing and tearing, do not have mechanical fault, can under harsh environment, use.(operating temperature :-25 degree ~+70 degree).Electronic label technology is made up of chip and antenna, and thickness is 0.01 centimeter, has independent 2 64 power ISNs, the chip IS015693 that adopts international standards.It has intelligent read and encrypted communication function, and it has unique id number, can enroll several data information simultaneously, and these information can be carried out Classification Management according to needs, also can forever preserve, and performance is high and safe and reliable.
Because adopt technique scheme, a kind of electronics Material evidence bag that the utility model provides has the following advantages: owing to adopt contactless hand inspection, avoid the error checked, information extraction is convenient, is easy to carry about with one, and is convenient to computing machine input and storage and preserves, ability with intelligent read and coded communication, and storage content is big, can discern a plurality of Material evidence bag interior label information simultaneously at a high speed, can not copy and revise material evidence information, safe, true and reliable.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details, comprises bag 1, bag 1 is provided with radio influence electronic tag 2.Bag 1 top is provided with bag along 3, and bag is provided with along 3 limits and is used for carrying out leak free bonding strip 4 with bag 1.Described electronic tag 2 includes the micro chip and the antenna that can be excited and send to read-write equipment radiofrequency signal non-contactly by relevant radio frequency read-write equipment.
The electronics Material evidence bag that the utility model is made, adopt the non-contact inductive mode promptly to write materials such as material evidence with the radio frequency read-write instrument, enter when having disposed radio frequency read-write equipment regional, or when being read by the radio frequency read-write equipment, this electronics Material evidence bag can be by automatic scan, read built-in information by Computer Database identification, finish need not any manual intervention automatically, can realize that material evidence is come in and gone out and movable automatic registration and management.The utility model not detailed description is known technology.
