Abstract
This invention relates to the biological character identification technique. It comprises fingerprint collection system, fingerprint identification subsystem, infrared vidicon subsystem, center control and data communication subsystem; gate inhibition subsystem. It identifies the fingerprint by the embedded system, so to increase the security of system. It can monitor around the clock by adopting the advanced fingerprint identification algorithm and MMS to realize wireless on site monitoring. It introduces the network fingerprint key concept, namely, under the normal state; there isn't any fingerprint templet in fingerprint gate inhibition. When entering or exiting the safe location, the control center calls out the fingerprint key of the authorized stuff in the fingerprint database and fingerprint templet and sends them to the fingerprint gate inhibition along with the survival factor through wireless links. The authorized stuff can enter and exit in the period that confirmed by the survival factor. After the survival time, the fingerprint gate inhibitor deletes the fingerprint key automatically.
Description
Technical field:
The present invention relates to biometrics identification technology.
Background technology:
Development and widespread use along with computer networking technology, the country and the important security information of military service and the safety problem of individual privacy information receive much attention, particularly after 911 incidents, confidential departments have proposed requirements at the higher level to turnover personnel's identification authentication mode.In traditional safety precaution field, gate inhibition and monitoring are separate and two kinds of safety-protection systems of the use of working in coordination.The value of supervisory system be monitoring or record authorized person at the scene behavior and when set up defences in the field in unauthorized personnel intrusion, can in time report to the police and stay the illegal act record; Gate control system then is to adopt mode initiatively, by control to the main thoroughfare, greatly prevented the intrusion of unauthorized personnel from normal channel, and can be by control when illegal act takes place to access door, restriction unauthorized personnel's scope of activities is to prevent illegal act or to reduce the loss.The present invention just can merge supervisory system and fingerprint entrance guard system physics by add the infrared photography technology on fingerprint entrance guard system, has greatly improved the safe precaution ability of system, is a kind of innovation to fingerprint entrance guard system.
Traditional personal identification method mainly contains: 1) identify label article (What you have), such as seal, key, certificate, credit card etc.; 2) identify label knowledge (What you know) is such as password or password etc.There is distinct disadvantage in these traditional identity discrimination methods: the article that have such as the individual are lost easily or are forged, personal identification number is forgotten easily or is misremembered even be stolen or the like, the jactitator that these all make system distinguish to have true identity person and obtain identify label thing or relevant information by some means.
The defective that present close product exists:
1, can only can not monitor the scene according to the fingerprint recognition switch of control gate as a result;
2, the algorithm for recognizing fingerprint performance is general, and mistake is refused rate than higher;
3, be difficult to make embedded system;
4, present product can't be supported the long-range mobile monitor of monitor staff;
5, present fingerprint access control product only provides Ethernet (RJ45), RS232, communication interfaces such as 485;
6, present off-line fingerprint gate inhibition product, finger print information (feature templates) all is stored in the fingerprint access control, can not implement scheduling.
Summary of the invention:
The objective of the invention is to: be the confidential departments' (as safe care registry and armory etc.) or the important civilian installation (approach tower like flying of country and army, aircraft handling chamber, bank vaults etc.) providing a kind of can carry out the band infrared photography of mobile remote monitoring day and night in 24 hours, the embedded fingerprint gate control system of radio function.
The present invention is by the fingerprint collecting subsystem; Fingerprint recognition subsystem; The infrared photography subsystem; Central authorities' control and data communication subsystem; Gate inhibition's subsystem is formed;
＜one〉fingerprint collecting subsystem
