[0030] The utility model is described in detail below in combination with the drawings and specific embodiments.

[0031] Refer to Figures 1 to 7As shown in the utility model provides a kind of rat detection alarm device based on microwave radar, in an embodiment, including fixed horizontal plate 1, rotating shell 2, radar assembly;The bottom of the fixed horizontal plate 1 is connected with a fixed vertical plate 11 at each end, and the rotating shell 2 is arranged between the two fixed vertical plates 11;One rotating shaft is installed at the two ends of the rotating shell 2 respectively, and the rotating shell 2 is rotatably connected with the fixed vertical plate 11 via the rotating shaft;Rotary drive mechanism 4 is also installed in the rotating shell 2, and the rotary drive mechanism 4 is connected with one of the rotating shafts;A launching tube 21 is also installed at the bottom of the rotating shell 2, and the radar signal emitted by the radar assembly is emitted outward from the launching tube 21;The radar assembly includes an MCU module, a radio frequency module, a signal processing module, a power supply module and an antenna modulation module installed in the rotating shell 2;The signal processing module and the power supply module are connected with the MCU module;The antenna modulation module is connected with the radio frequency module;The radio frequency module includes a radio frequency processing unit, a transmitting antenna and a receiving antenna connected with the radio frequency processing unit;The radio frequency processing unit is connected with the signal processing module.

[0032] In this embodiment, the fixed horizontal plate 1 can be hung on the cross beam in the house, the radar assembly works in the ISM band (24.0-24.25 GHz), the two ends of the rotating shell 2 are rotatably connected with a fixed vertical plate 11 via a rotating shaft, and the rotary drive mechanism 4 can drive the rotating shaft to rotate the rotating shell 2 relative to the fixed vertical plate 11 to adjust the angle of the radar assembly to adapt to different use environments. At the same time, for example, Figure 7 As shown, the radio frequency processing unit includes a voltage-controlled oscillator, a first power divider, a second power divider, a 90° phase shifter, a first mixer, a second mixer, a power amplifier and a low-noise amplifier;The input end of the first power divider is connected with the voltage-controlled oscillator, the first output end of the first power divider is connected with the transmitting antenna, and the second output end of the first power divider is connected with the input end of the second power divider;The first output end of the second power divider is connected with the first input end of the first mixer, and the second output end of the second power divider is connected with the input end of the 90° phase shifter;The second input end of the first mixer is connected with the first output end of the power divider;The first input end of the second mixer is connected with the output end of the 90° phase shifter, and the second input end of the second mixer is connected with the second output end of the power divider;The input end of the power divider is connected with the output end of the low-noise amplifier, and the input end of the low-noise amplifier is connected with the receiving antenna.

[0033] In addition, the signal processing module comprises two signal filtering and amplifying units, one of which is used for processing the IFI signal and the other is used for processing the IFQ signal; each of the signal filtering and amplifying units comprises a signal filtering unit and a signal amplifying unit connected with the signal filtering unit; the signal filtering unit is connected with the radio frequency processing unit, and the signal amplifying unit is connected with the MCU module.

[0034] The output end of the first mixer is used for outputting the IFI signal, and the output end of the second mixer is used for outputting the IFQ signal. In operation, the voltage-controlled oscillator generates a detection signal with a certain bandwidth according to the modulation signal (the antenna modulation module controls the transmission frequency of the radar at certain time intervals), which is transmitted to the transmitting antenna through the first power divider, and then is radiated to the area to be detected. If there is rodent activity in the area to be detected, the reflected signal is converted into a high-frequency electric signal by the receiving antenna after the signal hits the rodents, and then is amplified by the low-noise amplifier and transmitted to the second power divider. The second power divider distributes the signal to the first mixer and the second mixer, respectively. The first mixer and the second mixer mix the signal with the detection signal before the transmission of the transmitting antenna to obtain an intermediate frequency signal (IFI signal and IFQ signal). Then, the signal filtering unit of the signal processing module filters a part of the low-frequency part in the intermediate frequency signal (the intermediate frequency signal contains low-frequency noise signals and low-frequency signals reflected by non-targets, so as to reduce the modulation leakage problem caused by mixing). Subsequently, the signal amplifying unit amplifies the filtered signal and transmits it to the MCU module. The MCU module is built-in with an audio A / D conversion unit, which can convert the signal into a digital signal. Then, the distance information, speed information and direction information of the target can be extracted from the digital signal, so as to realize the positioning detection of the target. In this embodiment, the device can be used as a separate module, or can be connected in a network with multiple devices to monitor the intruding target in a region.
