After the radio frequency remote unit (pRRU) is star-connected and aggregated through the remote aggregation unit (RHUB), it is connected to the baseband processing unit (BBU). However, the roadway in the mine is linear, and the star connection affects the connection construction and installation.

[0003] Moreover, the remote aggregation unit (RHUB) in the mine is explosion-proof, with a large volume and heavy weight, making it difficult to install and maintain underground, and its use is restricted.

[0004] In addition, the underground radio frequency remote unit (pRRU) that needs to provide high speed is explosion-proof and intrinsically safe, with a large volume and heavy weight, making it difficult to install and maintain underground and unable to fully meet the requirements of underground intelligent applications.

Specific embodiments

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figure 1 shown, it is a schematic diagram of a 5G base station in the prior art. In the figure, the radio frequency remote unit (pRRU) is connected in a star shape and aggregated through a remote aggregation unit (RHUB) and then connected to the baseband processing unit (BBU). However, the underground roadway in the mine is linear, and this star connection affects the connection construction and installation.

[0027] As Figure 2 shown, it is a schematic diagram of the 5G base station equipment applied to underground coal mines of the present utility model, including:

[0028] A baseband processing unit 1 and at least one radio frequency remote unit 2. The radio frequency remote unit 2 includes an aggregation module 21 and a radio frequency module 22 that are connected to each other. The baseband processing unit 1 is connected to the radio frequency module 22 through the aggregation module 21.

[0029] The 5G base station equipment applied to underground coal mines of the present utility model changes the existing three-level architecture to a two-level architecture. Furthermore, the number of fault links is reduced. The baseband processing unit and the radio frequency remote unit are linearly connected, which fits the linear shape of the underground roadway in the coal mine and is convenient for installation and wiring.

[0030] The number of radio frequency remote units 2 is less than or equal to six. Multiple radio frequency remote units 2 are cascaded in sequence. The baseband processing unit 1 is connected to the first radio frequency remote unit 2. Adjacent radio frequency remote units 2 are connected by optical fibers. The radio frequency remote unit 2 has a 6-level cascading function by itself. When the number of radio frequency remote units 2 is less than or equal to six, multiple radio frequency remote units 2 can be cascaded in sequence.

[0031] The convergence module 21 includes data concatenation and merging functions. Assume that the end where the radio remote unit 2 is connected to the baseband processing unit 1 is the upper level. Data transmitted from the upper level to the lower level is downlink, and data transmitted from the lower level to the upper level is uplink.

[0032] like Figure 3 As shown, in the uplink, it includes: an uplink CA module 211, a compression module 212, a merging module 213, a cascade CA module 214, a first decompression module 215 and a first remote cache module 216. The first remote cache module 216, the merging module 213, the compression module 212 and the uplink CA module 211 are connected in sequence, the cascade CA module 214 is connected to the first decompression module 215, and the first decompression module 215 is connected to the merging module 213.

[0033] In the uplink direction, data from the upper-level remote radio unit 2 undergoes CA decompression and decompression, then merges with the data from the current remote radio unit 2. After merging, the data is compressed again and assigned to the original CA position. Because the frame headers must be aligned during merging, the data from the current remote radio unit 2 must be temporarily stored in the first remote radio buffer module 216.

[0034] In the downlink, it includes: a downlink CA module 217, a second decompression module 218 and a second remote cache module 219. The downlink CA module 217 is connected to the second decompression module 218, and the second decompression module 218 is connected to the second remote cache module 219.

[0035] In the downlink direction, the data of the upper level remote radio unit 2 is directly forwarded to the lower level remote radio unit 2. To ensure that the data of the remote radio units 2 at all levels arrive at the air interface at the same time, the downlink data also needs to be temporarily stored in the second remote buffer module 219.

[0036] The radio remote unit 2 is intrinsically safe and has the advantages of small size, light weight, easy installation and maintenance. It can be used in all places underground in coal mines and give full play to the function of underground emergency communication.

[0037] In summary, the 5G base station equipment of the present invention applied to underground coal mines has simplified the networking architecture and adopted a two-level architecture of BBU+pRRU, which reduces the failure links. The pRRUs support 6-level cascades, which fits the linear shape of underground tunnels in coal mines and is easy to install and wire. In addition, the pRRU is intrinsically safe, small in size, light in weight, easy to install and maintain, and can be used in all places underground in coal mines, giving full play to the function of underground emergency communication.
