This design of the electronic explosion-proof detector is based on the embedded. Its function is an electronic timing device with an explosives detection; the same time , it can be hidden listening devices and cameras to detect. Because the PN junction is an electronic device is the basic structure of chips, so the detection of electronic equipment is actually the detection of the PN junction. The electronic explosion-proof detector working principle is based on the principle of harmonic radar:the use of non-linear characteristics of PN junction, through the PN junction of the second harmonic generated by nonlinear interaction of the PN junction to detect and identify.The detector design, this paper targets the non-linear model, analysis and derivation of the harmonic goal of the detector scattering power formula, discussed the harmonic detector system implementation program, and to increase the system transmitter harmonic suppression capacity.The detector terminal realization,taking into account the detector display terminals based on embedded software, stability,reliability and practicality, I have decided to use operate system Linux. Detector terminal design includes construction of hardware platforms, software development platform to build and terminal application software development. The hardware platform to build the basis for the entire design, in this article it adopts mult-interface and high performance CPU S3C2410 according to ARM920T. The software platform constructing is based on the mode of host and target. Display control terminal application software development including:According to the display terminal software functional requirements, software module division; target information display program design and preparation of RS422 communication program.
