Abstract
|
The electronic explosion-proof detector designed in this paper is based on embedded . Its function is to detect explosives with an electronic timing device ; It also can covert listening devices and cameras to detect . Because the PN junction is constituted of an electronic device , in particular is the basic structure of the chip , so the detection of the electronic device is actually on the PN junction of the probe. The electronic explosion proof detector working principle is based on the the harmonic radar principle : the use of the nonlinear characteristic of the PN junction , the second harmonic generated by the nonlinear effect received by the PN junction to the PN junction for detection and identification . In the design of the detector , this paper the nonlinear model of the target , analysis and derivation of a the harmonic target detector scattering power formula , discussed harmonic detector system implementation , and improves system transmitter harmonic suppression capacity. Taking into account the realization of the detector terminal based the embedded detector stability , reliability and usefulness of the display terminal software , I decided that the operating system selected Linux . The detector terminal design including hardware platform , software development platform to build the terminal application software development . The hardware platform is the basis of the entire design , hardware platform using a multi-interface high - performance CPU S3C2410 ARM920T-based processor . Software development platform based on the host - target mode . Display control terminal application software development including : divided according to the functional requirements of the display terminal software , the software module ; goal of program design and RS422 communication program .
