Embodiment 1

[0015] like figure 1 As shown: Embodiment 1 According to the embodiment of the present invention, a novel alarm device with identification is provided, which is suitable for all occasions such as families, companies, stations, etc., including:

[0016] The induction module is the front end of the anti-riot device, which adopts pulse multi-system harmonic radar to collect signals of electronic explosives, and transmits the collected signals to the signal frequency processor;

[0017] The signal frequency processor and signal transmitter adopt linear frequency modulation continuous wave as the signal transmitted by the transmitter, and transmit the radio frequency signal with f as the center frequency. After detecting the second harmonic scattering of the PN junction, the signal received by the receiving antenna is the transmitted signal 2 times the frequency, the input power of the power amplifier is retreated from the 1dB compression point by 5-l0dB, and it works at a level fa...

Embodiment 2

[0022] The frequency of the RF local oscillator is the same as that of the useful RF channel, that is to say, the lF frequency of the receiver is zero, or the IF signal of the receiver starts from DC, and the intermediate frequency frequency is zero, there is no image interference problem, amplification and filtering It can be realized at DC, and only lower power consumption at DC can obtain the same gain as at higher intermediate frequency. Channel selection is performed at low frequency, and only low-frequency filters need to be used, and on-chip resistors and capacitors can be used. Realize filtering without adding an expensive and bulky surface acoustic filter (SAW).Placing the filter in the baseband can also achieve multi-bandwidth filtering without increasing the board area, because the filtering is done on-chip Yes, so the zero-IF method is very critical in the design of multi-mode receivers. In an ideal situation, the zero-IF receiver seems to be perfect, that is, to ch...

Description

technical field [0001] The invention relates to the field of system design, and relates to an anti-riot device for electronic explosives with frequency processing realized by adopting high-efficiency hardware circuits and chips. Background technique [0002] The traditional anti-riot devices on the market have single functions, and most of the explosion-proof detector technologies used are scanning imaging detection technology or nuclear energy detection technology and ultrasonic detection technology. Most of these technologies are imported from abroad, and these technologies are only used to detect the chemical composition of explosives to identify explosives, and cannot identify liquid explosives of timed explosive devices made of electronic principles. Detection of explosives. According to the most popular contemporary explosives are generally explosives with electronic timing devices, and electronic devices are used to detect them. Compared with other detectors, the det...
