Description
Technical field
The utility model relates to porjector technology field, is specifically related to a kind of fingerprint recognition projector.
Background technology:
The skin lines that everyone comprises fingerprint is different on pattern, breakpoint and point of crossing, presents uniqueness and constant throughout one's life.Accordingly, we just can be mapped a people with his fingerprint, by his fingerprint and the finger print data preserved in advance being compared, just can verify its true identity, Here it is fingerprint identification technology.Fingerprint recognition mainly according to the information such as lines, minutia of somatic fingerprint to operation or carried out identity authentication by operator, have benefited from hyundai electronics Integrated-manufacturing Techniques and algorithm research fast and reliably, start the daily life entering into us, become study in current biological detection the most deep, most widely used general, develop most proven technique.
Present projector on the market, often any user can operate on it, and security performance is poor, and therefore, in order to improve the security performance of projector, designing a kind of fingerprint recognition projector becomes problem demanding prompt solution.
Utility model content
The purpose of this utility model is to provide a kind of fingerprint recognition projector, to solve the above-mentioned multinomial defect caused in prior art.
A kind of fingerprint recognition projector, comprise the projection lens of housing and projection image, enclosure interior is provided with signal receiving part, processor, the laser cell of receiving processor signal and power module, outside is provided with fingerprint capturer, described power module comprises electronic switch and supplying cell, described signal receiving part, processor, laser cell, projection lens connect successively, described supplying cell is connected with electronic switch, fingerprint capturer, processor, and described electronic switch is connected with signal receiving part, processor, laser cell respectively.
Preferably, described processor is single-chip microcomputer, the one in ARM, DSP or FPGA.
Preferably, the installing plate that described housing lower surface is fixedly connected with, is provided with radiating fin below described installing plate.
Preferably, below described radiating fin, be provided with support, below described support, pedestal be installed.
Preferably, fan is provided with between described radiating fin and pedestal.
The utility model has the advantage of: this kind of fingerprint recognition projector, fingerprint capturer is combined with projecting apparatus system, when fingerprint recognition success, processor drives electronic switch to open, supplying cell starts signal receiving part, laser cell is powered, projector is started working, fingerprint recognition is unsuccessful, then supplying cell is not to signal receiving part, laser cell is powered, whole system can not carry out work, add security and the confidentiality of projector, the installing plate that housing lower surface is fixedly connected with, below installing plate, radiating fin is installed, support is provided with below radiating fin, below support, pedestal is installed, fan is provided with between radiating fin and pedestal, ensure that the heat dispersion of projector, avoid that projector Yin Wendu is too high causes damage.
