Description

Technical Field

[0001] The present invention relates to the technical field of radar telemetry devices, and more specifically to a small-sized frequency-modulated continuous-wave radar telemetry device. Background Art

[0002] The flash flood warning system is a complex systematic project that requires the coordinated cooperation of multiple technologies. Devices such as meteorological satellites, radar systems, and automatic rain gauges constitute the ground monitoring network, which collects key data such as rainfall and soil humidity in real time. The hydrological model predicts the possibility and influence range of flash floods by analyzing factors such as basin characteristics and topography. A frequency-modulated continuous-wave radar refers to a continuous-wave radar whose transmitted frequency is modulated by a specific signal, such as a meteorological radar. The frequency-modulated continuous-wave radar obtains the distance information of the target by comparing the difference between the frequency of the echo signal at any moment and the frequency of the transmitted signal at this moment. The distance is proportional to the frequency difference between the two. The radial velocity and distance of the target can be obtained after processing the measured frequency difference between the two. Compared with other ranging and velocity-measuring radars, the structure of the frequency-modulated continuous-wave radar is simpler.

Detailed Description of the Invention

[0026] The following will Figures 1-6 describe the specific embodiments of the present invention in detail with reference to the accompanying

[0027] The present invention provides a small-sized frequency modulation continuous wave radar telemetry device, which includes a top bin 1. The bottom of the top bin 1 is threadedly sleeved with a bottom bin 2. A frustum-shaped opening 5 penetrating through to the interior is formed at the top of the top bin 1. A lens 4 is fixedly connected to the inner wall of the frustum-shaped opening 5. An elastic telescopic platform assembly 3 is installed inside the top bin 1. A radar measurement unit, a telemetry system, and a solar charge controller are installed at the top and bottom of the elastic telescopic platform assembly 3. The bottom bin 2 stores a battery inside, which is used to supply power to the electrical components inside the top bin 1. An anti-push ring 8 is fixedly connected to the inner wall of the bottom bin 2. The bottom of the elastic telescopic platform assembly 3 is fixedly connected to a thrust ring cylinder 7 through a plurality of connecting arms 6. The elastic telescopic platform assembly 3 is set as a rotatable and detachable structure.

[0028] The device installs detection components through the elastic telescopic platform assembly 3 and is powered by the battery inside the bottom bin 2. The whole is integrated into the top bin 1 and the bottom bin 2 to form a sealed waterproof structure. When the top bin 1 and the bottom bin 2 are disassembled, the components installed on it can be automatically ejected outside the top bin 1 through the elastic force of the elastic telescopic platform assembly 3, which is convenient for maintenance. At the same time, by rotating the elastic telescopic platform assembly 3, it can be disassembled from the inside of the top bin 1, which is convenient for installing the components. After the top bin 1 and the bottom bin 2 are threadedly connected, the thrust ring cylinder 7 abuts against the anti-push ring 8, and the elastic telescopic platform assembly 3 shrinks through the anti-pushing effect of the anti-push ring 8, so that the components installed on the elastic telescopic platform assembly 3 are stored inside the top bin 1. In addition, through the cooperation of the thrust ring cylinder 7 and the anti-push ring 8, a sealed structure can be formed to improve the waterproof performance of the device. The threaded combination of the top bin 1 and the bottom bin 2 forms a cylinder with a radius of 4.5 cm and a height of 15 cm.

[0029] Preferably, the radar measurement unit uses an integrated transceiver circuit in the 122 GHz ISM frequency band and is docked with a data acquisition and control unit. The radar measurement unit includes: a low-noise amplifier LNA, a quadrature mixer, a polyphase filter, a voltage-controlled oscillator, a 32-frequency division output, a transmitting and receiving antenna. The lens 4 is used to narrow the beam of the transmitting antenna.

[0030] Preferably, the lens 4 converges the beam angle passed by the radar to 2 degrees.

[0031] This is convenient for improving the radar measurement accuracy and is more adaptable to narrow spaces.

[0032] Preferably, the telemetry system includes: a data acquisition and control unit, a wireless data transmission unit; the data acquisition and control unit includes a main control unit, a USB unit, a clock unit, and a power supply unit.

[0033] The clock unit wakes up the main control unit regularly. The main control unit turns on the power of the radar unit according to the timing acquisition time set by the system. After the radar unit is powered on, it starts to measure; the USB unit can be connected to a computer for configuration of relevant parameters.

[0034] Preferably, the wireless data transmission unit includes a 4G module and a SIM card unit.

[0035] After the data acquisition control unit reads the radar data, it transmits the data to the data control center through the wireless data unit. The data acquisition control unit reads the position information from the 4G module, and the control center can locate the position of the telemetry system.

[0036] Preferably, the side wall of the thrust ring cylinder 7 is provided with an inclined slope a, and the inner wall of the reverse thrust ring 8 is set as an inclined slope b.

[0037] When the top bin 1 and the bottom bin 2 are combined by threads, the thrust ring cylinder 7 is inserted into the inner cavity of the reverse thrust ring 8. Through the cooperation of the inclined slope a on the side wall of the thrust ring cylinder 7 and the inclined slope b on the inner wall of the reverse thrust ring 8, when the thrust ring cylinder 7 is inserted deeper into the inner cavity of the reverse thrust ring 8, the inclined slope a and the inclined slope are more tightly fitted, thereby enabling the reverse thrust ring 8 to exert a reverse thrust on the thrust ring cylinder 7, and a sealing effect is formed through this fitting relationship. When water seeps in from the connection gap between the top bin 1 and the bottom bin 2, it can prevent water from seeping into the bottom bin 2.

[0038] Preferably, the bottom ring 71 is fixedly connected to the side wall of the thrust ring cylinder 7, the top ring 72 is fixedly connected to the inner wall of the top bin 1, the positioning strip is fixedly connected to the side wall of the thrust ring cylinder 7 at the top of the bottom ring 71, the vertical chute is arranged on the inner wall of the top ring 72, and the positioning strip on the side wall of the thrust ring cylinder 7 is slidably sleeved in the vertical chute on the inner wall of the top ring 72.

[0039] After the elastic telescopic platform assembly 3 contracts, the whole thrust ring cylinder 7 moves upward. At this time, the bottom ring 71 moves upward and its top is closely attached to the bottom of the top ring 72, thereby forming a sealing effect to prevent water from seeping into the top bin 1. At the same time, through the cooperation of the positioning strip on the side wall of the thrust ring cylinder 7 and the vertical chute of the top ring 72, the rotation of the thrust ring cylinder 7 can be restricted, avoiding the situation that when the top bin 1 and the bottom bin 2 are combined by threads, due to the friction between the thrust ring cylinder 7 and the reverse thrust ring 8, the bottom bin 2 drives the thrust ring cylinder 7 to rotate, and further causing the elastic telescopic platform assembly 3 to rotate and disassemble.

[0040] Preferably, the elastic telescopic platform assembly 3 includes a main body mounting platform 31. Two telescopic columns 32 are fixedly connected to the top of the main body mounting platform 31. Two T-shaped column heads 33 are respectively fixedly connected to the tops of the two telescopic columns 32. Two anti-detachment arc tracks 35 adapted to the T-shaped column heads 33 are opened at the top of the inner wall of the top bin 1. Column grooves 34 are opened at the ends of the two anti-detachment arc tracks 35, and the two T-shaped column heads 33 are respectively slidably sleeved in the two anti-detachment arc tracks 35.

[0041] The hanging effect can be achieved through the sliding of the T-shaped column head 33 in the anti-detachment arc track 35. When the whole elastic telescopic platform assembly 3 rotates, the T-shaped column head 33 slides in the anti-detachment arc track 35. When reaching the end, the T-shaped column head 33 enters the inside of the column groove 34, and then it can be pulled out downward, thereby disassembling the elastic telescopic platform assembly 3.

[0042] Preferably, the telescopic column 32 includes a barrel wall 321. An inner column 322 is slidably sleeved in the inner cavity of the barrel wall 321. A column hole is formed at the bottom of the inner column 322. A spring 323 is fixedly connected to the top of the column hole. The bottom end of the spring 323 is fixedly connected to the bottom of the inner wall of the barrel wall 321.

[0043] When the inner column 322 slides in the barrel wall 321, the telescopic effect of the telescopic column 32 can be achieved. The elastic force of the spring 323 can make the telescopic column 32 automatically extend without external force, thereby ensuring the elastic effect of the elastic telescopic table assembly 3.

[0044] Preferably, a vertical anti - detachment groove is formed on the side wall of the inner column 322. An anti - detachment inlay block 324 is fixedly connected to the inner wall of the barrel wall 321. The anti - detachment inlay block 324 is slidably sleeved in the vertical anti - detachment groove on the side wall of the inner column 322.

[0045] Through this setting, the inner column 322 can be prevented from falling off from the barrel wall 321.
