For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0039] In the embodiments of the present invention, the term "a plurality of" refers to two or more, and other quantifiers are similar.

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] The related art realizes wireless network coverage of an explosion-proof area by setting explosion-proof base stations in the explosion-proof area. As Figure 1 shown, it is a structural schematic diagram of the related art for setting explosion-proof base stations in the explosion-proof area. Figure 1 In it, A1 to A4, B1 to B4, C1 to C4, and D1 to D4 refer to explosion-proof sub-areas. The related art sets an explosion-proof base station in each explosion-proof sub-area to realize wireless network coverage of the explosion-proof area. Specifically, as an example, Figure 1 it shows 16 explosion-proof sub-areas and a total of 16 explosion-proof base stations are set, namely explosion-proof base station 1 to explosion-proof base station 16.

[0042] To ensure the communication effect of the wireless network, the related art sets a plurality of explosion-proof base stations in the entire explosion-proof area, resulting in the problem of relatively high costs required to achieve wireless network coverage in the explosion-proof area.

[0043] To solve the above problems, the embodiments of the present invention provide a wireless network system, a base station, and an explosion-proof indoor distribution unit, which will be specifically described below.

[0044] First, a wireless network system provided by an embodiment of the present invention will be described.

[0045] The wireless network system provided by the embodiment of the present invention includes a base station and an explosion-proof indoor distribution unit. The explosion-proof indoor distribution unit includes an explosion-proof antenna. The explosion-proof indoor distribution unit is communicatively connected to the base station, and the explosion-proof indoor distribution unit is installed in an explosion-proof area where equipment needs to be explosion-proof treated.

[0046] The above base station is used to communicate with the explosion-proof indoor distribution unit and receive, send, and process communication signals.

[0047] The above explosion-proof indoor distribution unit is used to provide communication services for terminal devices in the explosion-proof area through the above explosion-proof antenna.

[0048] See Figure 2 , which is a schematic structural diagram of the first wireless network system provided by the embodiment of the present invention. It can be seen from Figure 2 that the base station is communicatively connected to the explosion-proof indoor distribution unit including the explosion-proof antenna. Through the explosion-proof antenna, the explosion-proof indoor distribution unit can provide communication services for terminal devices in its nearby area. Specifically, the number of explosion-proof indoor distribution units connected to the base station can be one or more, that is, n is greater than or equal to 1, and the number of explosion-proof indoor distribution units is set according to actual needs.

[0049] Specifically, the base station in the embodiment of the present invention can be a 5G (5th Generation Mobile Communication Technology) base station or a 4G (the 4th Generation Mobile Communication Technology) base station, or other types of base stations that meet actual requirements.

[0050] For the above base station, it can be set in an explosion-proof area or a non-explosion-proof area. In one embodiment of the present invention, the base station in the wireless network system is set in an explosion-proof area. See Figure 3 , which is a schematic structural diagram of the second wireless network system provided by the embodiment of the present invention. It can be seen from Figure 3 that since the base station is set in an explosion-proof area, the base station is an explosion-proof base station. As an example, Figure 3In it, explosion-proof sub-areas A1 to A4, B1 to B4, C1 to C4, and D1 to D4 are divided in the explosion-proof area, a total of 16 explosion-proof sub-areas. In each explosion-proof sub-area, an explosion-proof indoor distribution unit is set. For example, explosion-proof indoor distribution unit 1 is set in explosion-proof sub-area A1, explosion-proof indoor distribution unit 2 is set in explosion-proof sub-area A2, and so on. By analogy, explosion-proof indoor distribution unit 16 is set in explosion-proof sub-area D4. In each explosion-proof indoor distribution unit, an antenna is installed. For example, antenna 1 is installed in explosion-proof indoor distribution unit 1, antenna 2 is installed in explosion-proof indoor distribution unit 2, and so on. By analogy, antenna 16 is installed in explosion-proof indoor distribution unit 16. Specifically, the antennas mentioned in the embodiments of the present invention are all explosion-proof antennas.

[0051] In Figure 3 In the shown wireless network system, an explosion-proof base station is set as the only signal source and is communicatively connected to each explosion-proof indoor distribution unit. After the communication signal of the explosion-proof base station is transmitted to each explosion-proof indoor distribution unit, the wireless signal is released by the antenna in the explosion-proof indoor distribution unit, so as to realize the wireless network coverage in the explosion-proof area. Thus, the terminal devices in the explosion-proof area can communicate with the explosion-proof base station through the wireless network.

[0052] In another embodiment of the present invention, the base station is a non-explosion-proof base station and is located in a non-explosion-proof area where no explosion-proof treatment is required for the equipment. Refer to Figure 4 , which is the structural schematic diagram of the third wireless network system provided by the embodiment of the present invention. Compared with the embodiment shown in Figure 3 , the difference lies in that Figure 4 the base station in Figure 3 is a non-explosion-proof base station located in a non-explosion-proof area, and the rest is the same as that described in the embodiment shown in Figure 4 . In the embodiment shown in

[0053] , since the base station is located in a non-explosion-proof area and is a non-explosion-proof base station, its construction cost is lower than that of the explosion-proof base station. Therefore, setting the base station as a non-explosion-proof base station located in a non-explosion-proof area can further reduce the total cost of the wireless network system.

[0054] As can be seen from the above, in the wireless network system provided by the embodiments of the present invention, one base station is used as the only signal source, and explosion-proof indoor distribution units are configured in the explosion-proof area. The explosion-proof antennas included therein can be used to transmit signals to provide communication services for the terminals in the explosion-proof area. Compared with the related art that requires multiple explosion-proof base stations to be set in the explosion-proof area, the embodiments of the present invention only need to set explosion-proof indoor distribution units in the explosion-proof area and only need to set one base station. The cost of the explosion-proof indoor distribution unit is much lower than that of the explosion-proof base station, so the cost required to realize wireless network coverage in the explosion-proof area can be significantly reduced.

[0055] Moreover, in the related art, multiple explosion-proof base stations are set in the explosion-proof area. Due to the large volume of the explosion-proof base stations, they are not easy to install in some corners where wireless network coverage is required, which will affect the wireless network coverage effect. However, in the embodiment of the present invention, only explosion-proof indoor distribution units with small volume need to be installed in the explosion-proof area, which are easy to be set in the corners to ensure the wireless network coverage effect.

[0056] In one embodiment of the present invention, the explosion-proof indoor distribution unit is composed of passive devices, and the base station and the explosion-proof indoor distribution unit are powered by cables for the explosion-proof indoor distribution unit. In one example, the active devices in the wireless network system are arranged in the non-explosion-proof area, and the devices in the explosion-proof area of the wireless network system are passive devices. Specifically, flame-retardant feeder lines, such as radio frequency coaxial cables with the specification of SYV-75-12, can be used to connect the passive devices belonging to the wireless network system in the explosion-proof area.

[0057] It can be seen from the above description that in the related art, multiple explosion-proof base stations are set in the explosion-proof area, and power supply and signal transmission wiring need to be considered for each explosion-proof base station, resulting in high energy consumption and great construction difficulty. However, in the embodiment of the present invention, only one base station is used, and the explosion-proof indoor distribution unit is composed of passive devices. The connection between the base station and the passive devices and between the passive devices is simple. Compared with the related art, the energy consumption is small and the construction difficulty is small.

[0058] In the communication field, couplers and / or power dividers are often used to adjust the signal power or the number of signal paths. In one embodiment of the present invention, the explosion-proof indoor distribution unit also includes a coupler and a power divider. In one example, a coupler is communicatively connected to at least two of the base station, the power divider, the explosion-proof antenna, and other couplers; the power divider is communicatively connected to the coupler and the explosion-proof antenna. Specifically, reference can be made to Figure 5 , which is the structural schematic diagram of the fourth wireless network system provided by the embodiment of the present invention.

[0059] In Figure 5 , the base station is located in the non-explosion-proof area and is a non-explosion-proof base station. The base station is directly connected to coupler 1. The following takes the process of signal transmission from the base station to the antenna as an example to describe Figure 5 . Specifically, as an example, Figure 5 the power divider in

[0060] For the signal transmitted to coupler 3, after passing through coupler 3, it is divided into two paths. One path of the signal is transmitted to coupler 4, and the other path of the signal is directly transmitted to antenna 1; for the signal transmitted to coupler 4, after passing through coupler 4, it is divided into two paths. One path of the signal is directly transmitted to antenna 2, and the other path of the signal is transmitted to power divider 2; for the signal transmitted to power divider 2, after passing through power divider 2, it is divided into two paths. One path of the signal is directly transmitted to antenna 3, and the other path of the signal is transmitted to antenna 4.

[0061] For the signal transmitted to coupler 2, after passing through coupler 2, it is divided into two paths. One path of the signal is transmitted to power divider 1, and the other path of the signal is transmitted to coupler 5.

[0062] For the signal transmitted to coupler 5, after passing through coupler 5, it is divided into two paths. One path of the signal is directly transmitted to antenna 5, and the other path of the signal is transmitted to coupler 6; for the signal transmitted to coupler 6, after passing through coupler 6, it is divided into two paths. One path of the signal is directly transmitted to antenna 6, and the other path of the signal is transmitted to power divider 3; for the signal transmitted to power divider 3, after passing through power divider 3, it is divided into two paths. One path of the signal is directly transmitted to antenna 7, and the other path of the signal is transmitted to antenna 8.

[0063] For the signal transmitted to power divider 1, after passing through power divider 1, it is divided into two paths. One path of the signal is transmitted to coupler 7, and the other path of the signal is transmitted to coupler 9.

[0064] For the signal transmitted to coupler 7, after passing through coupler 7, it is divided into two paths. One path of the signal is directly transmitted to antenna 9, and the other path of the signal is transmitted to coupler 8; for the signal transmitted to coupler 8, after passing through coupler 8, it is divided into two paths. One path of the signal is directly transmitted to antenna 10, and the other path of the signal is transmitted to power divider 4; for the signal transmitted to power divider 4, after passing through power divider 4, it is divided into two paths. One path of the signal is directly transmitted to antenna 11, and the other path of the signal is transmitted to antenna 12.

[0065] For the signal transmitted to coupler 9, after passing through coupler 9, it is divided into two paths. One path of the signal is directly transmitted to antenna 13, and the other path of the signal is transmitted to coupler 10; for the signal transmitted to coupler 10, after passing through coupler 10, it is divided into two paths. One path of the signal is directly transmitted to antenna 14, and the other path of the signal is transmitted to power divider 5; for the signal transmitted to power divider 5, after passing through power divider 5, it is divided into two paths. One path of the signal is directly transmitted to antenna 15, and the other path of the signal is transmitted to antenna 16.

[0066] According to the above description, the communication signal sent by the base station can be transmitted to each antenna, and then the wireless signal is released by each antenna to achieve the wireless network coverage of the explosion-proof area.

[0067] Of course, Figure 5This is just an example. In other cases, different numbers of antennas may need to be set to release wireless signals; accordingly, the power divider and coupler need to be set according to different situations so that the signals of the base station can be transmitted to each antenna.

[0068] In a communication system, it is often necessary to control the signal power of the system. Especially for equipment deployed in explosion-proof areas, there are mandatory explosion-proof standard requirements. Specifically, in the specification of "GB / T 3836.1-2021 Explosive atmospheres - Part 1: Equipment - General requirements", for the threshold power of continuous emissions with a radio frequency of (9 kHz to 60 GHz) and pulse emissions with a pulse duration exceeding the thermal ignition time, clear limit regulations are made: the threshold power of continuous emissions with a radio frequency of (9 kHz to 60 GHz) and pulse emissions with a pulse duration exceeding the thermal ignition time shall not exceed the values in Table 1 below. Users are not allowed to set the program or control the software. See Table 1 for the radio frequency threshold power limit values of different types of equipment.

[0069] Table 1

[0070]

[0071] In an embodiment of the present invention, an attenuator is further included in the wireless network system to adjust the signal power of each component of the wireless network system. In the wireless network system provided by the embodiment of the present invention, the attenuator is communicatively connected to the base station and the explosion-proof indoor distribution unit, and the transmission power of the signal source in the entire wireless network system does not exceed the radio frequency threshold power value specified in Table 1. Exemplarily, based on the Figure 5 shown structure of the wireless network system, after adding an attenuator thereto, the signal power values of each part of the wireless network system are set to obtain Figure 6 the schematic structural diagram of the fifth wireless network system shown, which is different from the Figure 5 shown structure in that the signal output from the non-explosion-proof base station is transmitted to coupler 1 after passing through the attenuator.

[0072] As can be seen from Figure 6 , the output power of the non-explosion-proof base station is 100 W, and the corresponding signal strength power is 50 dBm; the attenuator (-20 dBm) means that the signal strength drops by 20 dBm after the signal output from the non-explosion-proof base station passes through this attenuator; the coupler 1 (10 dB) means that the coupling degree of this coupler is 10 dB, and the coupler 4 (7 dB) means that the coupling degree of this coupler is 7 dB. Figure 6 The identification meanings of other couplers in Figure 6Values such as -3.2 dB / 25 m and -0.256 dB / 2 m represent the feeder transmission loss. For example, -0.256 dB / 2 m between coupler 1 and coupler 3 means that the length of the feeder between coupler 1 and coupler 3 is 2 m, and the feeder transmission loss is 0.256 dB.

[0073] According to Figure 6 the settings of the signal power values of each part of the wireless network system shown, the statistical values of the output power of each antenna as shown in Table 2 below can be obtained.

[0074] Table 2

[0075]

[0076]

[0077] As can be seen from Table 2, according to Figure 6 the structure of the wireless network system shown, when the output power of the non-explosion-proof base station is 100 W, after the feeder transmission loss and the power splitter / coupler loss, the output power of each antenna is not greater than 15 dBm (i.e., 32 mW), and the overall output threshold power is 216 mW, and the designed output power meets the explosion-proof requirements.

[0078] Of course, Figure 6 the settings of parameters such as the signal power and the feeder length of each part in the wireless network system shown in the embodiment are only an example. In actual applications, the signal power, the feeder length and other parameters can be set according to needs, as long as the overall output threshold power of the wireless network system meets the explosion-proof requirements.

Specifically, in the structure of the explosion-proof indoor distribution unit shown, all fasteners need to be tightened firmly and there are anti-loosening measures, and the protection level of the explosion-proof indoor distribution unit is IP66.

[0095] The processor 903 may be a central processing unit (CPU), an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or a complex programmable logic device (CPLD), and the processor may also adopt a multi-core architecture.

[0096] In an embodiment of the present invention, the base station is communicatively connected to the explosion-proof indoor distribution unit, and the explosion-proof indoor distribution unit includes an explosion-proof antenna, and the explosion-proof indoor distribution unit is installed in an explosion-proof area where equipment needs to be explosion-proof processed; the above-mentioned base station is used to communicate with the explosion-proof indoor distribution unit, and transmit, receive, and process communication signals, so that the explosion-proof indoor distribution unit provides communication services for terminal devices in the explosion-proof area through the explosion-proof antenna.

[0097] As can be seen from the above, in the solution provided by the embodiment of the present invention, a base station is used as the only signal source, and an explosion-proof indoor distribution unit is configured in the explosion-proof area, and the explosion-proof antenna included therein can be used to transmit signals to provide communication services for terminals in the explosion-proof area. Compared with the related art that requires multiple explosion-proof base stations to be set in the explosion-proof area, the embodiment of the present invention only needs to set an explosion-proof indoor distribution unit in the explosion-proof area, and only one base station needs to be set, and the cost of the explosion-proof indoor distribution unit is much lower than that of the explosion-proof base station, so that the cost required to achieve wireless network coverage in the explosion-proof area can be significantly reduced.

[0098] Moreover, in the related art, multiple explosion-proof base stations are set in the explosion-proof area. Since the explosion-proof base stations are relatively large in volume, they are not easy to install in some corners where wireless network coverage is required, which will affect the wireless network coverage effect. In contrast, in the embodiment of the present invention, only explosion-proof indoor distribution units with small volume need to be installed in the explosion-proof area, which are easy to be set in the corners to ensure the wireless network coverage effect.

[0099] In one case, the above-mentioned explosion-proof indoor distribution unit is composed of passive devices, and the base station and the explosion-proof indoor distribution unit are powered by cables. In the related art, multiple explosion-proof base stations are set in the explosion-proof area, and power supply and signal transmission wiring need to be considered for each explosion-proof base station, resulting in high energy consumption and great construction difficulty. In contrast, in the embodiment of the present invention, only one base station is used, and the explosion-proof indoor distribution unit is composed of passive devices. The connection between the base station and the passive devices and between the passive devices is simple. Compared with the related art, the energy consumption is small and the construction difficulty is low.

[0100] In addition, the above-mentioned explosion-proof indoor distribution unit may further include couplers and power dividers. Among them, the coupler is communicatively connected to at least two of the base station, the power divider, the explosion-proof antenna, and other couplers; the power divider is communicatively connected to the coupler and the explosion-proof antenna. By using couplers and power dividers, communication signals can be transmitted between the base station and different antennas.

[0101] In an embodiment of the present invention, the above-mentioned base station is a non-explosion-proof base station and is located in a non-explosion-proof area where no explosion-proof treatment is required for the equipment. Since the base station is located in a non-explosion-proof area and is a non-explosion-proof base station, its construction cost is lower than that of the explosion-proof base station. Therefore, setting the base station as a non-explosion-proof base station located in the non-explosion-proof area can further reduce the total cost of the wireless network system.

[0102] In another embodiment of the present invention, the above-mentioned base station is communicatively connected to the explosion-proof indoor distribution unit through an attenuator, and the signal power of the component for receiving / transmitting signals can be adjusted through the attenuator.

[0103] Since the base station provided in the embodiment of the present invention and the foregoing wireless network system are based on the same inventive concept and have similar principles for solving problems, the embodiments of the base station and the wireless network system can be referred to each other, and the repeated parts will not be described again.

[0104] The base station in the embodiments of the present invention may include multiple cells that provide services to terminals. Depending on specific application scenarios, the base station may also be referred to as an access point, or may be a device in the access network that communicates with wireless terminal devices through one or more sectors over the air interface, or have other names. The base station can be used to mutually replace the received air frames and Internet Protocol (IP) packets, and act as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The base station can also coordinate the attribute management of the air interface. For example, the base station involved in the embodiments of the present invention may be an evolved Node B (eNB or e-NodeB) in a Long Term Evolution (LTE) system, a 5G base station (gNB) in a 5G network architecture (next-generation system), etc., or may also be a Home evolved Node B (HeNB), a relay node, a femto, a pico, a network test device, etc. The embodiments of the present invention do not limit this. In some network architectures, the base station may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be geographically separated.

The above-mentioned explosion-proof in-building distribution unit is communicatively connected to the base station and is used to provide communication services to terminal devices in the explosion-proof area through the explosion-proof antenna.

[0107] As can be seen from the above, in the solution provided by the embodiments of the present invention, a base station is used as the only signal source, and an explosion-proof in-building distribution unit is configured in the explosion-proof area. The explosion-proof antenna included therein can be used to transmit signals to provide communication services to terminals in the explosion-proof area. Compared with the related art that requires multiple explosion-proof base stations to be set up in the explosion-proof area, the embodiments of the present invention only need to set up an explosion-proof in-building distribution unit in the explosion-proof area, and only one base station needs to be set up. The cost of the explosion-proof in-building distribution unit is much lower than that of the explosion-proof base station, so that the cost required to achieve wireless network coverage in the explosion-proof area can be significantly reduced.

[0108] Moreover, in the related art, multiple explosion-proof base stations are set in the explosion-proof area. Since the explosion-proof base stations are relatively large in volume, they are not easy to install in some corners where wireless network coverage is required, which will affect the wireless network coverage effect. In the embodiments of the present invention, only explosion-proof indoor distribution units with small volume need to be installed in the explosion-proof area, which are easy to be set in the corners to ensure the wireless network coverage effect.

[0109] In one case, the above base station is a non-explosion-proof base station and is located in a non-explosion-proof area where no explosion-proof treatment is required for the equipment. Since the base station is located in a non-explosion-proof area and is a non-explosion-proof base station, its construction cost is lower than that of an explosion-proof base station. Therefore, setting the base station as a non-explosion-proof base station located in a non-explosion-proof area can further reduce the total cost of the wireless network system.

[0110] In one embodiment of the present invention, the above explosion-proof indoor distribution unit is composed of passive devices, and the base station and the explosion-proof indoor distribution unit are powered by a cable for the explosion-proof indoor distribution unit. In the related art, multiple explosion-proof base stations are set in the explosion-proof area, and power supply and signal transmission wiring need to be considered for each explosion-proof base station, resulting in high energy consumption and great construction difficulty. In the embodiments of the present invention, only one base station is used, and the explosion-proof indoor distribution unit is composed of passive devices. The connection between the base station and the passive devices and between the passive devices is simple. Compared with the related art, the energy consumption is small and the construction difficulty is small.

[0111] In another embodiment of the present invention, the above explosion-proof indoor distribution unit further includes a coupler and a power divider. Among them, the coupler is communicatively connected to at least two of the base station, the power divider, the explosion-proof antenna, and other couplers, and the power divider is communicatively connected to the coupler and the explosion-proof antenna. By using the coupler and the power divider, the communication signal can be transmitted between the base station and different antennas.

[0112] In still another embodiment of the present invention, the explosion-proof indoor distribution unit is communicatively connected to the base station through an attenuator, and the signal power of the component for receiving / transmitting signals can be adjusted through the attenuator.

[0113] Since the explosion-proof indoor distribution unit provided by the embodiments of the present invention and the foregoing wireless network system are based on the same inventive concept and have similar principles for solving problems, the embodiments of the explosion-proof indoor distribution unit and the wireless network system can be referred to each other, and the repeated parts will not be described again.
