DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with embodiments, which are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in the field without creative work are all within the scope of protection of the present invention.

[0027] Embodiment 1:

[0028] like Figure 1-2 As shown, an integrated portable radio ultra-wideband monitoring and direction-finding device comprises a first monitoring antenna 1, a second monitoring antenna 2, a third monitoring antenna 4 and a broadband digital receiver unit 3, wherein the first monitoring antenna 1 is arranged on the upper part of the second monitoring antenna 2, and the second monitoring antenna 2 is arranged on the broadband digital receiver unit 3. Figure 4 As shown, the third monitoring antenna 4 is hingedly arranged at the lower part of the broadband digital receiver unit 3. After the third monitoring antenna 4 is folded, it is arranged close to the side wall of the second monitoring antenna 2. After the third monitoring antenna 4 is unfolded, it is arranged in a circular array, and the vibrator of the third monitoring antenna 4 is staggered with the broadband digital receiver unit 3 in the horizontal plane. The first monitoring antenna 1, the second monitoring antenna 2, and the third monitoring antenna 4 are respectively connected to the broadband digital receiver unit 3 by signal. In this embodiment, the first monitoring antenna 1 is a 30MHz-26.5GHz monitoring antenna. The second monitoring antenna 2 is a 1GHz-26.5GHz direction-finding antenna. The third monitoring antenna 4 is a 30MHz-1GHz low-end direction-finding antenna.

[0029] like Figure 3As shown, in this embodiment, the first monitoring antenna 1 is arranged on the upper part of the second monitoring antenna 2 through a first connecting component, the first connecting component includes an antenna mounting seat 9, a waterproof locking cover 8, the antenna mounting seat 9 is arranged on the outer cover of the second monitoring antenna 2, and a accommodating limit groove 10 is provided on the bottom surface of the antenna mounting seat 9, and a guide groove 13 matching the accommodating limit groove 10 is provided on the bottom surface of the first monitoring antenna 1, a conical clamping platform 17 is provided at the bottom end of the first monitoring antenna 1, a conical limit portion 7 matching the conical clamping platform 17 is provided at one end of the waterproof locking cover 8, and a through hole for the first monitoring antenna 1 to pass through is opened at one end of the conical limit portion 7 of the waterproof locking cover 8, and the waterproof locking cover 8 is screwed on the antenna mounting seat 9.

[0030] During assembly, the waterproof locking cover 8 is passed through the long straight section of the first monitoring antenna 1 through the through hole opened at one end of the conical limiting portion 7, and then the guide groove 13 protruding from the end of the first monitoring antenna 1 is inserted into the accommodating limiting groove 10 of the antenna mounting seat 9 to achieve pre-assembly, and then the waterproof locking cover 8 is tightened by the knob to achieve the fixation and quick disassembly of the first monitoring antenna 1.

[0031] Since the first monitoring antenna 1 and the second monitoring antenna 2 realize a structure of rapid assembly and disassembly, a quick-release connector is required to realize the signal transmission between the first monitoring antenna 1 and the broadband digital receiver unit 3. In this embodiment, the first monitoring antenna 1 is connected to the broadband digital receiver unit 3 by signal through a quick-release connector, and the quick-release connector includes a quick-release connector plug 15 and a quick-release connector socket 12, the quick-release connector socket 12 is fixed in the accommodating limit groove 10, the quick-release connector socket 12 is connected to the broadband digital receiver unit 3 by signal, the quick-release connector plug 15 is fixed in the guide groove 13, the quick-release connector plug 15 is connected to the first monitoring antenna 1 by signal, and when the guide groove 13 of the first monitoring antenna 1 is set in the accommodating limit groove 10 of the antenna mounting seat 9, the quick-release connector plug 15 is plugged into the quick-release connector socket 12.

[0032] In this embodiment, the first connecting component also includes an O-ring 14 and a waterproof rubber pad 6. The O-ring 14 is arranged between the end of the first monitoring antenna 1 and the end of the accommodating limit groove 10, and the waterproof rubber pad 6 is arranged between the conical clamping platform 17 of the first monitoring antenna 1 and the conical limit portion 7 of the waterproof locking cover 8. The O-ring 14 and the waterproof rubber pad 6 are compressed as the waterproof locking cover 8 is tightened to achieve the purpose of waterproofing. At the same time, a drainage port is designed on the side of the antenna mounting seat 9 to prevent rainwater from accumulating in the antenna mounting seat 9 after erroneous operation.

[0033] In this embodiment, a plurality of inwardly recessed storage grooves are provided on the side walls of the outer cover of the second monitoring antenna 2, and the storage grooves are used to accommodate the folded and collapsed third monitoring antenna 4. The cross section of the outer cover of the second monitoring antenna 2 is petal-shaped.

[0034] Wideband digital receivers will generate electromagnetic interference during operation, so a metal shielding layer must be designed on the outside. The 30MHz-1GHz low-end direction-finding antenna will be interfered by the large metal body of the broadband digital receiver when it works in the horizontal direction. According to this design requirement, combined with the space conditions of each array element inside the antenna, the outer cover of the 1GHz-26.5GHz direction-finding antenna is designed to be in the shape of petals by utilizing the gaps between the array elements. This design allows the 30MHz-1GHz low-end direction-finding antenna to be folded and placed in the petal cavity of the antenna, avoiding occupying the external space of the antenna and thus increasing the size of the antenna. Figure 5 shown.

[0035] In this embodiment, the third monitoring antenna 4 is rotatably connected to the broadband digital receiver unit 3 through the first damping hinge 18. The third monitoring antenna 4 includes a plurality of groups of third monitoring sub-antennas, each of which includes a third monitoring sub-antenna element 20 support arm 19, a second damping hinge 21 and two third monitoring sub-antenna elements 20. One end of the support arm 19 of the third monitoring sub-antenna element 20 is rotatably connected to the broadband digital receiver unit 3 through the first damping hinge 18, and the other end of the support arm 19 of the third monitoring sub-antenna element 20 is rotatably connected to the two third monitoring sub-antenna elements 20 through two second damping hinges 21, respectively.

[0036] like Figure 6 As shown, in order to ensure the convenience of using the 30MHz-1GHz low-end direction-finding antenna during the unfolding and folding process, it is considered to design a first damping hinge 18 at the rotating shaft. Since the 30MHz-1GHz low-end direction-finding antenna needs to avoid the large-area metal body of the broadband digital receiver unit 3 when working, the 30MHz-1GHz low-end direction-finding antenna needs to be at a certain angle to the horizontal when unfolded. The design utilizes the structural limit of the arm 19 of the third monitoring sub-antenna vibrator 20 and its own gravity and the second damping hinge 21, and stays in the working position after being unfolded. When the antenna is folded, the circular tube part of the antenna arm is inserted into the antenna clamp to achieve the folding and fixing of the 30MHz-1GHz low-end direction-finding antenna.

[0037] In order to reduce the size of the 30MHz-1GHz low-end direction-finding antenna vibrator after storage, the 30MHz-1GHz low-end direction-finding antenna vibrator is designed to be a folding structure, the second damping hinge 21 is used to control the rotation amplitude, and the limit structure of the hinge seat of the first damping hinge 18 is used to control the unfolding and folding position of the third monitoring sub-antenna vibrator 20. This design can ensure that the third monitoring sub-antenna vibrator 20 can be unfolded to a state perpendicular to the horizontal plane when the support arm 19 of the third monitoring sub-antenna vibrator 20 is at an angle of 45° to the horizontal plane, while meeting the requirements of the aperture of the 30MHz-1GHz low-end direction-finding antenna.

[0038] like Figure 7 As shown, in this embodiment, a support 24 is provided at the bottom of the shell of the broadband digital receiver unit 3, and a tripod 5 is threadedly connected to the support 24. An air inlet 23 and an air outlet 25 are provided at the bottom of the shell of the broadband digital receiver unit 3, and rubber feet 22 distributed in a ring array are provided at the bottom edge of the shell of the broadband digital receiver unit 3.

[0039] The broadband digital receiver unit 3 at the bottom of the portable radio ultra-wideband monitoring and direction-finding device adopts a bottom-in and bottom-out heat dissipation method, and the air inlet 23 and the air outlet 25 are both distributed at the bottom of the receiver. This design can ensure that rainwater cannot enter the inside of the device through the heat dissipation holes when the device is erected. In addition, the rubber feet 22 at the bottom can ensure that the device can be placed directly on the ground while ensuring that there is enough air inlet space at the bottom. Through thermal design analysis and experiments, it is verified that this heat dissipation design meets the working needs of the equipment.

[0040] like Figure 8 As shown, the support 24 is installed on the bottom plate 27 of the broadband digital receiver unit 3, and the tripod support 24 is installed on the tripod 5. The three-threaded design inside the support 24 and the three-threaded design outside the tripod support 24 can be quickly screwed and connected. During the installation process, the portable radio ultra-wideband monitoring and direction-finding device can be fixed on the tripod 5 by aligning the positioning block 26 in the middle of the receiver base with the tripod support 24 and then rotating it clockwise by about 270°. The positioning block 26 is designed with a chamfer to ensure smooth insertion and rotation. The entire installation process only takes a few seconds to complete, achieving the purpose of rapid installation.

[0041] The integrated portable radio ultra-wideband monitoring and direction-finding device provided by the present invention integrates a plurality of direction-finding antennas of different frequency bands (including 30MHz-1GHz, 1-3GHz, 3-8GHz, 8-25.6GHz), a 30MHz-26.5GHz monitoring antenna and a broadband digital receiver unit 3. The portability of the device is improved. The petal-shaped cover structure design and the folding mechanism design of the low-end direction-finding antenna solve the problem of large size and unfolded aperture of the 30MHz-1GHz low-end direction-finding antenna, while avoiding electromagnetic interference. The bottom-in and bottom-out heat dissipation structure design of the broadband digital receiver at the bottom of the device prevents rainwater from entering the device and causing damage. The three-thread quick-release structure design improves the speed of setting up the radio ultra-wideband monitoring and direction-finding device, and realizes quick disassembly and installation of the device.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
