[0018] The present invention provides a debris flow monitoring device, such as Figure 1-2 As shown, it includes a frame 10, a radar module 20, a transceiver antenna 30, a transceiver switch 40 and a data processor 50. The two ends of the frame 10 are respectively connected to a back plate 60 and a radar cover 70. A heat conductive layer 170 is coated on one side of the back plate 60, and a mounting bracket 80 is fixed on the back plate 60. The radar module 20 is fixed on the heat-conducting layer 170, and the radar module 20 is used to generate radio frequency signals and analyze echo signals; the transceiver antenna 30 is fixed on the frame 10, and the transceiver antenna 30 is located on the inner side of the antenna cover 70; the transceiver antenna 30 is used to radiate radio frequency signals to the area to be monitored to form electromagnetic waves, and receive echo signals from the area to be monitored; the transceiver switch 40 is fixed on the mounting bracket 80, and the mounting bracket 80 is located between the radar module 20 and the transceiver antenna 30; the transceiver switch 40 connects the radar module 20 and the transceiver antenna 30, and the transceiver switch 40 is used to transmit radio frequency signals forward to the transceiver antenna 30, and to perform reverse isolation; the data processor 50 is fixed on the inner side of the back panel 60, and the data processor 50 is connected to the radar module 20, and the data processor 50 is used to analyze and judge the analyzed signals, and output monitoring results.
[0019] Further, such as Figure 3As shown, the radar module 20 includes a transmitter 21, a receiver 22, a frequency synthesizer 23 and a signal processor 24, and the transmitter 21, the receiver 22, the frequency synthesizer 23 and the signal processor 24 are all fixed on the back plate 60; the transmitter 21 is connected to the transceiver switch 40, and the transmitter 21 is used to generate a radio frequency signal and modulate, filter and amplify it; the receiver 22 is connected to the transceiver switch 40 and the frequency synthesizer 23, and the receiver 22 is used to receive the echo signal and perform frequency conversion, filtering, amplification and demodulation on it; the frequency synthesizer 23 is connected to the transmitter 21 and the receiver 22, and the frequency synthesizer 23 is used to provide a reference frequency; the signal processor 24 is respectively connected to the transmitter 21, the frequency synthesizer 23, the receiver 22 and the data processor 50, and the signal processor 24 is used to pre-process the echo signal.
[0020] In this embodiment, the transmitter 21, the receiver 22, the frequency synthesizer 23 and the signal processor 24 are integrated to form a radar module 20. Compared with the prior art in which each module is self-contained and connected by corresponding arrangement through cables, the use of cables is reduced, thereby reducing the volume and structural complexity of the debris flow monitoring device, and eliminating the electromagnetic interference that may be generated by the cables; the radar module 20 and the data processor 50 are installed on the back plate 60, and a mounting bracket 80 is provided to install the transceiver switch 40, so that the transceiver switch 40 is located between the radar module 20 and the transceiver antenna 30 in space, adapting to the cable direction of the transceiver switch 40, improving the neatness of the arrangement inside the debris flow monitoring device, and further reducing the overall volume of the debris flow monitoring device. Coating a thermal conductive layer 170 on the back plate 60 can improve the heat dissipation effect inside the debris flow monitoring device.
[0021] Further, such as Figure 4 As shown, the back plate 60 is provided with a heat-conducting boss 90 adapted to the data processor 50, and the surface of the heat-conducting boss 90 is coated with a heat-conducting layer 170. The heat-conducting boss 90 is provided according to the shape of the data processor 50, so that the heat-conducting boss 90 accurately fits the data processor 50 (chip) to achieve conduction heat dissipation. Figure 5 As shown, a heat dissipation tooth 100 is provided on one side of the back plate 60 away from the heat conducting layer 170 , through which the heat conducted to the back plate 60 can be efficiently contacted with the outside air and dissipated into the outside air, thereby improving the heat dissipation effect.
[0022] Furthermore, if Figure 6-7As shown, a step 110 is formed on the side wall of one end of the frame 10, and the radome 70 is located at the step 110.

In addition, a waterproof and breathable respirator 160 is also provided on the shell, which can achieve sealing while ensuring breathability.
[0023] In order to facilitate connection, a management (M&C) interface, a data interface, and a power interface are also provided on the frame 10. The two interfaces of power supply and data are normally used. The data interface is a standard network port, through which a computer or other transceiver device with a network interface can be connected to receive the monitoring data output by the radar data processor. The management interface is a multi-core composite interface, which may only be used when the radar system needs to be deeply set and adjusted. Its multi-core composite has a VGA interface and a USB interface, which are connected to the corresponding interface of the data processor 50. The external display, keyboard and mouse can be connected through this interface to directly operate the data processor 50 and perform in-depth operations on the data processor 50.
[0024] The working principle of the debris flow monitoring device of the present invention is as follows: The radio frequency signal is generated by the transmitter 21, modulated according to the reference frequency provided by the frequency synthesizer 23, filtered, amplified, and input into a radio frequency interface of the transceiver switch 40, and output from the adjacent radio frequency interface into the transceiver antenna 30, and the radio frequency signal is radiated to the monitored area to form an electromagnetic wave. The electromagnetic wave is reflected after irradiating the object in the monitored area. Due to the Doppler effect, when there is a moving target in the monitored area, the transceiver antenna 30 receives the reflected signal (echo signal) of the monitored area, passes through the transceiver switch 40, and enters the receiver 22 in a direction. The receiver 22 performs a radio frequency modulation on the echo signal according to the reference frequency provided by the frequency synthesizer 23. The data processor 50 performs frequency conversion, followed by filtering, amplification and demodulation, and the input signal processor 24 is used to analyze the demodulated echo signal to obtain multiple frequency offset signals; the frequency offset signal may include the time delay between the transmitted signal and the received signal and the change in the frequency of the electromagnetic wave; the data processor 50 calculates and analyzes the frequency offset signal, extracts the target information and the disaster warning level information and outputs it to the signal processor 24, and then sends it through the data interface to realize the monitoring of debris flow. The target information may include whether there is a moving object, the moving speed of the moving object, the distance between the moving object and the radar, the relative size of the moving object, and other information. Specifically, the data processor 50 can calculate the distance between the target object and the radar based on the time delay between the transmitted signal and the received signal. The speed of the target object can be calculated based on the change in the frequency of the electromagnetic wave.
