Description

Technical Field

[0001] The utility model relates to the field of micro-station control, in particular to a distributed micro-station joint switching device. Background Art

[0002] After several generations of development, the mobile network has gradually developed into a high-frequency one. The coverage of high-frequency signals is small, resulting in high investment and operating costs. If the layout of base stations is unreasonable, some base stations will be resource-constrained and consume more electricity, while some base stations will be too busy, resulting in low communication quality.

[0003] The existing technology generally solves this problem by removing idle equipment and filling busy equipment. By counting the load rate of each base station, some base stations with low load rates are removed, and then equipment is added to some base stations with high load rates.

[0004] However, in some buildings, due to fluctuations in tenants, repeated adjustments are often required, wasting manpower and resources. Utility Model Content

[0035] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0036] A distributed micro base station 2 joint switching device, as shown in the signal enhancement unit 1, includes:

[0037] A plurality of micro base stations 2;

[0038] A plurality of signal enhancement units 1 and a plurality of switching units corresponding to each signal enhancement unit 1, each signal enhancement unit 1 is distributed at a different position, and each signal enhancement unit 1 is selectively connected to a micro base station 2 through a corresponding switching unit;

[0039] The switching unit includes a plurality of single-pole double-throw switches, and the number of the single-pole double-throw switches is 2 n -1, n is a natural number.

[0040] By connecting the signal enhancement unit 1 to the micro base station 2 through the switching unit, the micro base station 2 to which the signal enhancement unit 1 is connected can be modified through the switching unit, which can be flexibly adjusted. When the demand of each office fluctuates, there is no need to re-split the idle and busy micro base stations 2, thereby improving efficiency.

[0041] In this embodiment, the single-pole double-throw switches in the switching unit are divided into n layers, and the number of each layer is 2 n-1 , among all SPDT switches:

[0042] The common end of the single-pole double-throw switch of the first layer is connected to the output end of the signal enhancement unit 1, and the normally open end and the normally closed end are respectively connected to the common ends of two different single-pole double-throw switches of the next layer.

[0043] The common end of the SPDT switch in the middle layer is connected to the normally open end or normally closed end of a SPDT switch in the upper layer, and the normally open end and normally closed end are respectively connected to the common ends of two different SPDT switches in the lower layer.

[0044] The common end of the single-pole double-throw switch of the last layer is connected to the normally open end or normally closed end of a single-pole double-throw switch of the previous layer, and the normally open end is connected to a micro base station 2.

[0045] The switching unit is implemented using a 2x cascaded double-pole double-throw switch, which has higher reliability and stronger anti-interference ability than multi-position switches.

[0046] The normally open ends of all single-pole double-throw switches in the last layer of the switching unit are connected to different micro base stations 2.

[0047] The switching unit further comprises a plastic housing, in which the single-pole double-throw switch is arranged.

[0048] The signal enhancement unit 1 is an external antenna.

[0049] The signal enhancement unit 1 is located at the ceiling of each office in the office building.

[0050] In the switching unit, the value range of n is 1-3. Specifically in this embodiment, the value of n is 3. Figure 1As shown, K1 is the single-pole double-throw switch of the first layer, K2 and K3 are the single-pole double-throw switches of the second layer, and K4~K7 are the single-pole double-throw switches of the third layer. By adjusting the state of each switch, the signal enhancement unit 1 can be connected to a micro base station 2. For example, when K1, K2 and K4 are closed and the others are disconnected, the micro base station 2 connected to the normally open end of K4 is connected to the signal enhancement unit 1.

[0051] In addition, in this embodiment, the single-pole double-throw switch is a relay, which has higher reliability and stability.

[0052] In certain embodiments, such as Figure 2 As shown, the switching unit also includes a controller 21 and a wireless signal transceiver 22, and the controller 21 is connected to the coils of each relay and the wireless signal transceiver 22. Generally, the wireless signal transceiver 22 is a Bluetooth module. Specifically, the controller 21 can be controlled by sending a binary sequence through a data string, for example, 11010000, indicating that K1, K2 and K4 are closed, and the others are disconnected.

[0053] Based on the present application, the micro base station 2 to which the signal enhancement unit is connected can be realized by adjusting the state of each single-pole twin switch, thereby realizing load transfer, and rapid adjustment can be made when load changes occur frequently. Compared with directly adjusting the equipment, the adjustment workload is smaller. Compared with directly preparing redundant micro base stations, the signal enhancement unit 1 has a lower cost and a longer life, which can reduce costs.
