Description

Technical Field

[0001] The present invention relates to the technical field of electromagnetic testing, and particularly to a multi-functional movable monitoring vehicle for electromagnetic environment testing. Background Technique

[0002] With the rapid development of technology, the electromagnetic environment has become increasingly complex. Applications such as radar and satellite signals are becoming more and more widespread, and the communication signal frequency is continuously moving towards the high-frequency band. In this context, electromagnetic environment testing is crucial for ensuring the normal operation of various electronic devices and communication systems. In actual application scenarios, such as communication signal monitoring in urban areas, electromagnetic environment guarantee at large event sites, and electromagnetic interference detection in field scientific research projects, fixed monitoring stations are difficult to deploy flexibly and cannot meet the diverse monitoring needs in different scenarios. Therefore, a movable monitoring vehicle is used to achieve the testing.

[0003] In the prior art, as disclosed in Chinese Patent Publication No.: CN113721082A, a method for monitoring electromagnetic radiation in a regional environment is disclosed. This method uses an electromagnetic monitoring vehicle to monitor the radio frequency electromagnetic environment in the monitoring area, obtains a radio frequency electromagnetic environment distribution map through monitoring, and simultaneously conducts statistical analysis on the monitoring results to obtain the current situation results of radio frequency electromagnetic environmental pollution in urban areas of each city.

[0004] However, in the prior art, there is no lightning rod installed on the electromagnetic monitoring vehicle. When encountering lightning weather during monitoring, lightning may directly strike the test monitoring vehicle. The strong lightning current will cause the temperature of the metal components of the vehicle to rise and lead to local melting. The impact force of the lightning will cause the body structure to deform and the glass to break. Even if the lightning does not directly strike the vehicle, the strong electromagnetic pulse generated by it will form a strong electromagnetic field in the surrounding space, thus interfering with the normal operation of the test instruments in the vehicle and affecting the accuracy and integrity of the test results.

[0005] Therefore, we propose a multi-functional movable monitoring vehicle for electromagnetic environment testing to facilitate solving the problems raised above. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. During use, through the protective cover with an inclined surface, it can prevent rainwater and dust from accumulating on the top of the protective cover and avoid rainwater from seeping into the interior of the protective frame. When testing the electromagnetic environment, by simultaneously starting the two hydraulic cylinders, the two hydraulic cylinders simultaneously lift the protective cover upward. At this time, the testing equipment is powered on and is used to measure and analyze the electromagnetic environment. When encountering a lightning environment, the lightning will be led down by the lightning rod, and then pass through the guiding soft wire and the guiding hard wire to reach the grounding wire. Both the guiding soft wire and the guiding hard wire are made of copper materials, so that the lightning current can be conducted quickly and smoothly. When reaching the monitoring point, the grounding wire is connected to the conductor of the monitoring point grounding body, so that the lightning current flows into the ground through the grounding body, and the lightning current is introduced deep into the ground, thereby realizing safe discharge.

[0019] 2. During use, by starting the servo motor, its output shaft rotates, driving the connected rotating shaft to rotate, and ultimately driving the wheel hub and tire to rotate, enabling the monitoring vehicle to move. Among them, the servo motor can be installed through the mounting bracket. When the monitoring vehicle encounters an uneven road surface during movement, vibrations will occur. Then, when the wheel hub and tire bump up and down, the reinforcement frame sleeved outside the rotating shaft drives the damping rod to move up and down. At this time, the support spring elastically absorbs and releases the energy brought by the vibration, thus playing a buffering role. When it is necessary to change the moving direction of the monitoring vehicle, by starting the forward and reverse motor, its output shaft rotates, driving the connecting shaft to rotate. Since the connecting shaft is connected to the connecting frame and the mounting bracket through the fixing rod, when the connecting shaft rotates, the tire will rotate around the connecting shaft, and the limiting rod moves inside the moving slot, thus realizing the change of the moving direction of the monitoring vehicle.

[0020] 3. During use, the radio frequency front-end module can receive and process electromagnetic signals. The signal processing module converts the received and processed analog radio frequency signals into digital signals for subsequent digital signal processing. Next, the frequency synthesis module provides stable and accurate local oscillator signals for the radio frequency front-end module and the signal processing module, which are used for operations such as signal mixing and down-conversion. Then, the data storage and transmission module stores the collected electromagnetic signal data and the processed analysis results, and transmits the monitoring data to the control center at the back end. Among them, the power management module is used to convert the externally input power into DC power of different voltage levels required by each module, and it can provide power support for each module. In addition, the two core functions of the control and display module are to control the monitoring equipment and display the working status, monitoring data, and analysis results of the monitoring equipment.

The outer surfaces of the four sides of the protective cover 304 are all inclined. When it rains, the rainwater will flow down along the protective cover 304, preventing rainwater and dust from accumulating on the top of the protective cover 304 and avoiding rainwater from seeping into the interior of the protective frame 301. When testing the electromagnetic environment, by simultaneously starting two hydraulic cylinders 302, the two hydraulic cylinders 302 simultaneously lift the protective cover 303 upward.

[0035] Embodiment Two: Figure 1 - Figure 9 As shown, moving components 2 are fixedly connected to both sides of the two support base plates 1. The moving component 2 includes a vehicle frame 201. A mounting frame 204 is fixedly connected to the top of the vehicle frame 201. A fixing frame 202 is fixedly connected to the top of the mounting frame 204. A forward and reverse motor 203 is arranged inside the fixing frame 202. The output shaft of the forward and reverse motor 203 penetrates through the mounting frame 204 to its outside. The output shaft of the forward and reverse motor 203 is fixedly connected to a connecting shaft 205. One end of the connecting shaft 205 is fixedly connected to a fixing rod 206. One end of the fixing rod 206 is fixedly connected to a connecting frame 209. A mounting frame 213 is fixedly connected to the bottom of the connecting frame 209. A servo motor 214 is arranged on the inner wall of the mounting frame 213. The output shaft of the servo motor 214 is fixedly connected to a rotating shaft 215. A reinforcing frame 216 is slidably connected to the outer surface of the rotating shaft 215. A damping rod 217 is slidably connected to the inner wall of the reinforcing frame 216. Support springs 218 are arranged outside both damping rods 217. A hub 207 is arranged at one end of the rotating shaft 215. A tire 208 is installed outside the hub 207. Limiting rods 212 are fixedly connected to the far ends of the two damping rods 217. A support frame 210 is fixedly connected to the bottom of the support base plate 1. Activity grooves 211 are respectively formed in the outer surface of the support frame 210 near the top and the bottom. The outer surfaces of each limiting rod 212 are respectively slidably connected to the inner walls of each activity groove 211.

[0036] In this embodiment, during use, the four moving components 2 are respectively fixed on both sides of the two support bottom plates 1 to realize the movement of the monitoring vehicle. When moving, the servo motor 214 is started to rotate its output shaft, thereby driving the connected rotating shaft 215 to rotate, and finally driving the wheel hub 207 and the tire 208 to rotate, enabling the monitoring vehicle to move. Among them, the mounting frame 213 can be used to mount the servo motor 214. When the monitoring vehicle encounters an uneven road surface during movement, vibrations will occur. Then, when the wheel hub 207 and the tire 208 bump up and down, the reinforcing frame 216 sleeved outside the rotating shaft 215 drives the damping rod 217 to move up and down, and the support spring 218 elastically absorbs and releases the energy brought by the vibration at this time, thus playing a buffering role. When it is necessary to change the moving direction of the monitoring vehicle, the forward and reverse motor 203 is started to rotate its output shaft, thereby driving the connecting shaft 205 to rotate. Since the connecting shaft 205 is connected to the connecting frame 209 and the mounting frame 213 through the fixing rod 206, then, when the connecting shaft 205 rotates, the tire 208 will rotate around the connecting shaft 205, and the limiting rod 212 moves inside the moving slot 211, thereby realizing the change of the moving direction of the monitoring vehicle. Among them, the driving speed settings of the servo motors 214 in the four moving components 2 are the same, while the driving of the four forward and reverse motors 203 is set separately.

[0037] Embodiment 3: Figure 1 - Figure 9 As shown, it further includes: a multifunctional movable monitoring vehicle system for electromagnetic environment testing, which includes: a radio frequency front-end module 8, a signal processing module 9, a frequency synthesis module 10, a data storage and transmission module 11, a power management module 12, and a control and display module 13.

[0038] The radio frequency front-end module 8 is used to receive electromagnetic signals and perform filtering processing on the signals. The signal processing module 9 is used to convert the received radio frequency signals into digital signals. The frequency synthesis module 10 is used to provide stable and accurate local oscillator signals for the radio frequency front-end module 8 and the signal processing module 9, which are used for operations such as signal mixing and down-conversion. The data storage and transmission module 11 is used to store the collected electromagnetic signal data and the processed analysis results. The power management module 12 is used to convert the externally input power into DC power of different voltage levels required by each module. The control and display module 13 is used to initialize, configure, and control each module, and it is also used to display the working status, monitoring data, and analysis results of the monitoring device.

[0039] In this embodiment, during use, the radio frequency front-end module 8 can receive and process electromagnetic signals. A broadband antenna, a radio frequency filter, and a low-noise amplifier are provided in the radio frequency front-end module 8. The broadband antenna is a key component for receiving electromagnetic signals and needs to have broadband characteristics to effectively receive electromagnetic signals within a relatively wide frequency range, so as to increase the frequency band coverage of the monitoring device. The radio frequency filter is used to filter the signals received by the antenna, suppress out-of-band interference signals, and improve the purity of the signals. The low-noise amplifier is at the front end of signal reception, amplifies weak radio frequency signals, and minimizes the introduced noise as much as possible to improve the sensitivity of the monitoring device. Then, the signal processing module 9 converts the received and processed analog radio frequency signals into digital signals for subsequent digital signal processing. Next, the frequency synthesis module 10 provides a stable and accurate local oscillator signal for the radio frequency front-end module 8 and the signal processing module 9 for operations such as signal mixing and downconversion. Then, the data storage and transmission module 11 stores the collected electromagnetic signal data and the processed analysis results, and transmits the monitoring data to the control center at the back end. Among them, the power management module 12 converts the externally input power into DC power of different voltage levels required by each module and can provide power support for each module.

The outer surfaces of the four sides of the protective cover 304 are all inclined. When it rains, the rainwater will flow down along the protective cover 304, preventing rainwater and dust from accumulating on the top of the protective cover 304 and avoiding rainwater from seeping into the inside of the protective frame 301. When testing the electromagnetic environment, by simultaneously starting two hydraulic cylinders 302, the two hydraulic cylinders 302 simultaneously lift the protective cover 303 upward. At this time, the testing device 7 is powered on and electrically connected to the controller 5 and the mobile battery 6, so that the testing device 7 can be automatically controlled by the controller 5. Among them, the testing device 7 uses an electric field and magnetic field probe, an electromagnetic radiation tester, and a spectrum analyzer, and multiple devices are used in combination to receive and sense the electric and magnetic field signals in space and convert them into electrical signals for the testing device 7 to measure and analyze. When encountering a lightning environment, the lightning will be led down by the lightning rod 401, and then pass through the guiding flexible wire 402 and the guiding rigid wire 403 to reach the grounding wire 404. Both the guiding flexible wire 402 and the guiding rigid wire 403 are made of copper material, so that the lightning current can be conducted quickly and smoothly. When reaching the monitoring point, the grounding wire 404 is connected to the conductor of the monitoring point grounding body, and the lightning current flows into the ground through the grounding body. During use, the four moving components 2 are respectively fixed on both sides of the two support bottom plates 1 to realize the movement of the monitoring vehicle. When moving, by starting the servo motor 214, its output shaft rotates, thereby driving the connected rotating shaft 215 to rotate, and finally driving the wheel hub 207 and the tire 208 to rotate, so that the monitoring vehicle can move. Among them, the mounting frame 213 can be used to mount the servo motor 214. When the monitoring vehicle encounters an uneven road surface during movement, vibrations will occur. Then, when the wheel hub 207 and the tire 208 bump up and down, the reinforcing frame 216 sleeved outside the rotating shaft 215 drives the damping rod 217 to move up and down, and the support spring 218 elastically absorbs and releases the energy brought by the vibration at this time. When it is necessary to change the moving direction of the monitoring vehicle, by starting the forward and reverse motor 203, its output shaft rotates, thereby driving the connecting shaft 205 to rotate. Since the connecting shaft 205 is connected to the connecting frame 209 and the mounting frame 213 through the fixing rod 206, then, when the connecting shaft 205 rotates, the tire 208 will rotate around the connecting shaft 205, and the limiting rod 212 moves inside the movable slot 211, thereby realizing the change of the moving direction of the monitoring vehicle. Among them, the drive speed settings of the servo motors 214 in the four moving components 2 are the same, while the drives of the four forward and reverse motors 203 are set separately. During use, the radio frequency front-end module 8 can be used to receive and process electromagnetic signals. A broadband antenna, a radio frequency filter, and a low-noise amplifier are set in the radio frequency front-end module 8. The broadband antenna is the key component for receiving electromagnetic signals.It is necessary to have broadband characteristics and be able to effectively receive electromagnetic signals within a relatively wide frequency range to increase the frequency band coverage of the monitoring device. The RF filter is used to filter the signals received by the antenna, suppress out-of-band interference signals, and improve the purity of the signals. The low-noise amplifier is at the front end of signal reception, amplifying weak RF signals while minimizing the introduced noise to improve the sensitivity of the monitoring device. Then, the received and processed analog RF signals are converted into digital signals by the signal processing module 9 for subsequent digital signal processing. Next, the frequency synthesis module 10 provides stable and accurate local oscillator signals for the RF front-end module 8 and the signal processing module 9 for operations such as signal mixing and down-conversion. Then, the data storage and transmission module 11 stores the collected electromagnetic signal data and the processed analysis results, and transmits the monitoring data to the control center at the back end. Among them, the power management module 12 is used to convert the externally input power into DC power of different voltage levels required by each module, and it can provide power support for each module.
