Description

Technical Field

[0001] This invention relates to the field of communications, and particularly to the field of communication signal reception. Background Technology

[0002] Currently, a satellite TV receiver, commonly known as a "dish," is a device capable of receiving satellite TV programs. It consists of a parabolic antenna, a feedhorn, a low-noise block downconverter (LNB), and a satellite receiver. Satellite TV receivers have greatly facilitated access to outside information in some rural areas, but they have also raised certain concerns. There are two types of satellite receivers: prime-fed and offset-fed. Prime-fed antennas have a larger reflective surface area, hence the common name "big dish"; conversely, offset-fed antennas have a smaller reflective surface area, hence the name "small dish" or "small ear." In extremely remote mining areas, similar to maritime communication methods, signal receiving devices are needed for communication.

[0003] Patent document with application number "CN201210119935.2" discloses a dish-type signal receiver, including a metal reflector and an L-shaped bracket. A reflector plate is disposed at the top of the L-shaped bracket. The receiver also includes a mounting strip, which is bolted to the metal reflector. The bottom end of the L-shaped bracket is bolted to the mounting strip. The advantages of the dish-type signal receiver are that it has a U-shaped mounting plate, making it convenient to adjust the orientation of the metal reflector and allowing for quick positioning.

[0004] Patent document with application number "CN201410603463.7" discloses a signal receiver, including a base, a cover, a reflector, and a signal receiving device. The base and the cover are connected, the inner side of the base is connected to the reflector, the reflector is provided with a signal receiver, and the cover is provided with a control button connected to the signal receiver, thereby improving the efficiency of the signal receiver.

[0005] Patent document with application number "CN201510905416.2" discloses a simple signal receiver, consisting of a receiving disk and a base. The technical solution involves fixing exposed aluminum wire segments to a support column, connecting the ends of the aluminum wire segments with thin iron wire to form an open umbrella-like shape, and then attaching wires to the aluminum wire segments to form the receiving disk. A universal joint connects the support column and the base, allowing the support column to rotate freely on the base. The structure is simple, energy-saving, environmentally friendly, and highly practical.

[0006] However, the above-mentioned communication signal receiving devices cannot meet the communication needs of the mining area. Due to the special requirements of the terrain in the mining area, if ordinary signal receiving devices are used, problems such as low signal reception rate and poor performance will occur. When using ordinary signal receiving devices in the mining area, the signal divergence loss rate is high and the reception rate is poor. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a full-coverage mining area communication signal receiving device that can solve the problems of low reception rate and poor effect of communication signals in mining areas.

The central feed source 20 has a cylindrical structure. The reflector is a plurality of discs with through holes in the center. One end of the threaded rod 30 passes through the geometric center of the pot body 10 from the inner curved surface of the pot body 10 and is fixed to the locking mounting assembly 200. The other end of the threaded rod 30 passes through the central feed source 20 and the reflector in sequence. The position locking nut 60 is used to fix the reflector.

[0009] The reflector includes a micro reflector 41, a small reflector 42, a medium reflector 43, a large reflector 44, and a bottom reflector 45. The diameters of the micro reflector 41, small reflector 42, medium reflector 43, large reflector 44, and bottom reflector 45 increase sequentially. The distances from the micro reflector 41, small reflector 42, medium reflector 43, large reflector 44, and bottom reflector 45 to the central feed source 20 decrease sequentially. There is only one small reflector 42, medium reflector 43, large reflector 44, and bottom reflector 45, while there are multiple micro reflectors 41.

[0010] The diameter of the micro reflector 41 is 5 cm, the diameter of the small reflector 42 is twice the diameter of the micro reflector 41, the diameter of the medium reflector 43 is 1.3 times the diameter of the small reflector 42, the diameter of the large reflector 44 is 1.3 times the diameter of the medium reflector 43, and the diameter of the bottom reflector 45 is 1.3 times the diameter of the large reflector 44.

[0012] The pressure sensing device 50 includes a connecting line 51 and a pressure sensor 52. The connecting line 51 passes through the pot body 10, and the sensing head of the pressure sensor 52 faces the end of the micro reflector 41. The pressure sensor 52 is fixed to the large reflector 44 and the bottom reflector 45.

[0013] The locking mounting assembly 200 includes a U-shaped locking bracket 201, a locking nut 202, and a locking body 203. The two ends of the U-shaped locking bracket 201 pass through the locking body 203 and are locked to the side mounting sleeve 90 by the two locking nuts 202. The side mounting sleeve 90 is fixed to the output shaft of a rotating device.

[0014] The pot body 10 includes a central connecting part 11 and a side arc-shaped part 12. The two side arc-shaped parts 12 are fixed into a U-shaped structure by the central connecting part 11.

[0024] Please see Figure 1-4A full-coverage communication signal receiving device for mining areas includes a boiler body 10, a central feed source 20, a threaded rod 30 (a straight rod with external threads), several reflector plates, a pressure sensing device 50, several position locking nuts 60, a bottom locking nut 70, a side mounting sleeve 90, and a locking mounting assembly 200. The boiler body 10 includes a central connecting part 11 and side arc-shaped parts 12 connecting the two ends of the central connecting part 11. The boiler body 10 is U-shaped. The central feed source 20 is located in the middle of the boiler body 10. The threaded rod 30 passes through the boiler body 10 and is fixedly connected to the locking mounting assembly 200. The reflector plates are provided with through holes. A threaded rod 30 passes through a hole in the reflector plate. Position locking nuts 60 are provided on both the upper and lower sides of the reflector plate. The position locking nuts 60 fix the reflector plate to the threaded rod 30. Bottom locking nuts 70 are welded and fixed to the lower part of the threaded rod 30 (in contact with the right or lower surface of the bottom reflector plate 45) to limit the position of the reflector plate. A pressure sensing device 50 is provided on the locking mounting assembly 200. The pressure sensing device 50 passes through the pot body 10 and the sensing end of the pressure sensing device 50 faces the reflector plate. The locking mounting assembly 200 includes a U-shaped locking frame 201, two locking nuts 202, and a locking body 203. The two ends of the U-shaped locking frame 201 pass through the locking body 203 and are locked to the side mounting sleeve 90 by the two locking nuts 202, so that the pot body 10 is fixed to the side mounting sleeve 90. The side mounting sleeve 90 is mounted on a rotating device. Adjusting the positions of several reflector discs and the position locking nut 60 allows for adjustment of the signal reflection position and angle, thereby improving the signal reception rate. This highly flexible adjustment method enables the signal reflection to reach its optimal state based on the calculated position and orientation information, maximizing the signal reception rate. It is very suitable for the unique terrain and orientation conditions of mining areas, solving the problems of low signal reception rate and poor performance.

[0025] In actual use, the pot body 10 is vertical relative to the ground. The rotating device makes the pot body 10 rotate vertically. The unique U-shaped setting of the pot body 10 is very suitable for high-level satellite communication transmission. Compared with the ordinary pot body facing upward, this transmission method has a higher reception rate and a lower signal loss rate.

[0026] The reflector is divided into micro reflector 41, small reflector 42, medium reflector 43, large reflector 44, and bottom reflector 45. The size of the reflector is between 5cm and 30cm. The maximum size of the pot body 10 is between 100cm and 130cm.

[0027] Specifically, the diameter of the miniature reflector 41 is 5cm, and the diameter of the small reflector 42 is twice that of the miniature reflector. The diameter of the medium-sized reflector 43 is 1.3 times that of the small reflector, the diameter of the large reflector 44 is 1.3 times that of the medium reflector, and the diameter of the bottom reflector 45 is 1.3 times that of the large reflector 44. It should be noted that in actual use, it is not necessary to use all sizes of reflectors; the specifications and quantity of reflectors can be adjusted according to requirements.

[0028] In one embodiment, when all reflectors are used, the following arrangement can be made: the small reflector 42 is positioned between the micro reflector 41 and the medium reflector 43, and the large reflector 44 is positioned between the medium reflector 43 and the bottom reflector 45. Of course, other selections or adjustments can be made as needed to improve signal reception.

[0029] The unfolded view of the pot body 10 is elliptical. The pressure sensing device 50 includes a connecting line 51 and a pressure sensor 52 connected to the connecting line 51, with the sensing end of the pressure sensor 52 facing the reflector. The purpose of setting the pressure sensor 52 is to solve the interference problem between the reflector and the pot body, and to set the lowest position line through the pressure sensor 52.

[0030] The thread specification of the threaded rod 30 is M10.

[0031] A communication method for a full-coverage mining area communication signal receiving device includes the following steps:

[0032] Position calculation steps: Calculate the relative positional relationship between the satellite position and the signal receiver position; in the position calculation steps, the relative positional relationship includes elevation angle, high frequency input signal band, satellite azimuth information, and signal receiver azimuth information.

[0033] Reflector adjustment steps: Rotate the position locking nut to adjust the position and number of reflectors;

[0034] Signal detection steps: Start normal transmission and check if the signal reception rate meets the requirements. If not, proceed to the next step.

[0035] Secondary adjustment steps: Readjust the position and number of reflectors, and check whether the signal reception rate meets the requirements.
