Description

Technical Field

[0001] This utility model relates to the field of radar equipment technology, and in particular to a dual-band ground-based slope radar. Background Technology

[0002] Micro-change monitoring radar is a device used to monitor slopes and unstable rock masses in the field. Based on principles such as microwave imaging and differential interferometry, it detects subtle slope displacements in a timely manner by periodically scanning a predetermined slope using a double-track measurement method and employing multiple two-dimensional radar images of the observation scene. Ground-based micro-change monitoring radar systems offer advantages such as all-weather operation, wide coverage, and high precision, providing a new and more efficient solution for geological disaster monitoring and early warning. With the continuous promotion and application of ground-based micro-change monitoring radar, new and higher demands are being placed on its early warning capabilities.

[0003] Existing ground-based micro-change radar monitoring systems have the following drawbacks:

[0004] (1) The operating frequency band is a single frequency band for monitoring. The wavelength of microwaves affects the penetration performance and resolution of radar signals. Single-band operation is greatly affected by the vegetation and weather conditions on site, which increases the radar error data and the probability of false alarms. Furthermore, it is necessary to remove erroneous data, which is a large workload. Due to the limited size of the radar, when the wavelength of the radar signal is long, it has better penetration but low azimuth resolution; when the wavelength of the radar signal is short, the signal penetration is poor but the azimuth resolution is high. It is impossible to simultaneously achieve both good penetration and high resolution.

[0005] (2) Existing ground-based micro-deformation radar can actively transmit signals and then recover the echo reflection signals reflected by the target, while simultaneously completing the monitoring of micro-deformation over a large area. In actual field applications, such equipment requires on-site control equipment such as computers to control the radar and analyze data. Currently, the computers used in such equipment are mostly external rugged computers or desktop hosts, which increases the difficulty of system transportation and deployment. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a dual-band ground-based micro-change monitoring radar. The two radars can use the dual bands simultaneously or at different times to monitor the same slope area, which can obtain better monitoring accuracy and provide better early warning accuracy. Moreover, no external computer is required, making transportation and deployment more convenient and simple.

[0007] This invention is implemented as follows: a dual-band ground-based slope radar, comprising...

[0008] A turntable has an internal drive device and a top rotating platform. The drive device drives the rotating platform to rotate. A conductive slip ring is installed inside the rotating platform.

[0009] A host is fixedly mounted on a rotating platform. Inside the host are a power module, an industrial control computer, a first filter, a second filter, a first radar module, and a second radar module. The power module is electrically connected to the conductive slip ring. The first filter, the second filter, and the industrial control computer are all connected to the power module. The industrial control computer is communicatively connected to the first radar module and the second radar module. The first radar module is electrically connected to the first filter, and the second radar module is electrically connected to the second filter.

[0010] A first antenna is fixedly mounted on the host and is communicatively connected to the first radar module;

[0011] The first and second radars are fixedly mounted on the host and are communicatively connected to the second radar module.

[0012] Furthermore, the first antenna is in the X-band, and the second antenna is in the Ku-band.

[0013] Furthermore, the driving device is an electric motor.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] like Figures 1 to 3 The present invention provides a dual-band ground-based slope radar, comprising a turntable 1, a main unit 2, a first antenna 3, and a second antenna 4.

[0022] The turntable 1 is equipped with a drive device (not shown) inside, and a rotating platform 11 is provided on the top. The drive device drives the rotating platform 11 to rotate. The drive device is a motor. The rotating platform 11 is equipped with a conductive slip ring 12 inside, which serves as a connection for circuit communication links.

[0023] The host 2 is fixedly mounted on the rotating platform 11. Inside the host 2 is a power module 21, an industrial control computer 22, a first filter 23, a second filter 24, a first radar module 25, and a second radar module 26. The power module 21 is electrically connected to the conductive slip ring 12. The first filter 23, the second filter 24, and the industrial control computer 22 are all connected to the power module 21. The first filter 23 and the second filter 24 are used to suppress electromagnetic interference, particularly noise in the power supply lines or control signal lines. The industrial control computer 22 is communicatively connected to the first radar module 25 and the second radar module 26. The industrial control computer 22 is used to control the first radar module 25 and the second radar module 26 to generate and receive radar signals, and to process the radar signals. The first radar module 25 is electrically connected to the first filter 23, and the second radar module 26 is electrically connected to the second filter 24.

[0024] The first antenna 3 is an X-band antenna, which is fixedly mounted on the host 2 and is communicatively connected to the first radar module 25; the second antenna 4 is a Ku-band antenna, which is fixedly mounted on the host 2 and is communicatively connected to the second radar module 26. When in use, the host 2 is connected to the turntable 1, and the radar can be controlled by powering on, which is simple and convenient.

[0025] The turntable 1 described in this invention can control the rotation of the host 2 with high precision and provide stable position information. This invention employs a dual-band radar system, using a high-precision turntable as a synchronization signal. The Ku-band has high resolution and the X-band has high penetration, allowing simultaneous or time-division monitoring of the same slope area. This achieves both better penetration with long waves and better resolution with short waves. Simultaneous monitoring with both radars results in better monitoring accuracy and improved early warning precision.

[0026] This invention integrates an industrial control computer 22 within the main unit 2. This industrial control computer 22 has multiple data and control interfaces. The communication network port of the turntable, the radar network port, and its controlled components can all be connected separately through the multiple network ports of the industrial control computer 22. Integrating this into the radar main unit reduces the number of external devices required for the radar system. Furthermore, the motherboard of the industrial control computer 22 has multiple network ports, eliminating the need for an internally integrated switch, thus reducing the number of modules, lowering the radar system cost, reducing the failure rate, and increasing the stability of the radar system. This invention's ground-based micro-change monitoring radar integrates control, data processing, and data interaction, reducing deployment difficulty and facilitating system monitoring through remote control.

[0027] This utility model of a ground-based micro-change monitoring radar employs dual-band operation, combining long-wave and short-wave bands to effectively overcome environmental influences, increase the equipment's applicability to various scenarios, improve the accuracy of monitoring data, reduce workload, and provide accurate early warnings. By incorporating an industrial control computer within the main unit, it eliminates the need for an external computer or desktop host, reducing the number of system components, lowering system costs, increasing system usability, and enhancing overall equipment stability, making transportation and deployment more convenient and simple. This utility model is a dual-band ground-based slope radar with a simple structure, convenient operation, and no need for an external computer, facilitating operation and deployment.
