Description

Network signal isolation transmission method, device and system

Technical Field

The present application relates to the field of signal transmission technologies, and in particular, to a method, an apparatus, and a system for isolated transmission of network signals.

Background

The application scenarios of the wireless network are becoming more and more extensive, and for example, the application in the hospital service scenario is taken as an example, the intranet (i.e. local area network) services of the hospital, such as mobile nursing, mobile ward round, etc., are also applied to the wireless network. In addition, the wireless external network (i.e. public network) of the hospital is generally a simple open network, and is transmitted on the same equipment as the wireless internal network, and only logical isolation is performed. However, such a deployment is easy to be hacked to attack the intranet by accessing the intranet from the extranet, and thus a great deal of value information in the intranet may be leaked.

In the related art, the following scheme is generally adopted to physically isolate the wireless intranet from the wireless extranet so as to improve the network security. One of the schemes is to deploy an internal network and an external network respectively by adopting two completely independent wireless networks so as to realize the physical isolation of the internal network and the external network. However, such a design requires high cost, and has many maintenance points, which is not favorable for daily maintenance. The other scheme is that an intranet board card and an outer network board card are respectively inserted into a base station, the transmission of signals of the inner network and the outer network is realized by staggering frequency bands, and all the signals enter a hospital ward through a feeder line. The scheme can realize physical isolation of the internal network and the external network, but the signal transmission of the internal network and the external network can only support one frequency band respectively, and the frequency bands of the internal network and the external network need to be staggered, otherwise, the problem of crosstalk is easily caused.

In the related art, different types of physical isolation schemes adopted for the wireless intranet and the wireless extranet have the problems that higher cost needs to be consumed, the number of maintenance points is large, and the daily maintenance is not facilitated, or the signal transmission of the intranet and the extranet can only support one frequency band respectively, and the frequency bands of the intranet and the extranet need to be staggered.

In view of the above problems, embodiments of the present application provide a network signal isolation transmission method, which can more easily implement physical isolation of different network signals, reduce deployment cost, and ensure network security.

The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Fig. 1 is a schematic flow chart of a network signal isolation transmission method according to an embodiment of the present application.

Referring to fig. 1, an embodiment of the present application provides a network signal isolation transmission method, which includes:

step S110, receiving network signals sent by different network terminals, carrying out signal shunting on the network signals through different power dividing circuits, and sending the network signals to a signal transceiver through different feeder lines in the same group; wherein, different groups of feeders correspond to different signal transceivers.

The different network terminals may include two different network terminals, for example, a first network terminal and a second network terminal. The first network terminal is an internal network terminal, and the second network terminal is an external network terminal; or the first network end is a first intranet end, and the second network end is a second intranet end; or the first network end is a first external network end, and the second network end is a second external network end. It can be understood that the first intranet end and the second intranet end are different intranet ends which are independent of each other. The first external network end and the second external network end are different and mutually independent external network ends. Taking the intranet and the extranet in the hospital as an example, the first network signal may be from the intranet end of the hospital, and the second network signal may be from the extranet end.

Accordingly, different network terminals respectively transmit corresponding network signals, such as a first network signal from a first network terminal and a second network signal from a second network terminal. In the application, the same wireless access point ap (access point) is used to receive and forward the first network signal and the second network signal. Further, in an embodiment, a first network signal sent by a first network terminal and a second network signal sent by a second network terminal are received respectively; and after the first network signal is shunted through the first power dividing circuit, the first network signal is sent to the signal transceiver, the second network signal is shunted through the second power dividing circuit, and the first network signal and the second network signal are sent to the signal transceiver through different feeder lines.

It can be understood that each network signal is shunted through different power dividing circuits in the wireless access point, and then further sent to different signal transceivers through corresponding feeders in different groups. Further, the set of feed lines comprises two different feed lines, namely a first feed line and a second feed line. And aiming at the same signal transceiver, a corresponding group of feeder lines are adopted for connection. And aiming at different signal transceivers, corresponding different groups of feeder lines are adopted for connection. When the number of the signal transceivers is more than one, namely, one signal transceiver is arranged in different areas, different groups of feeders are respectively connected with the corresponding signal transceivers in each area, so that only one wireless access point is needed to correspond to the signal transceivers in different areas through the different groups of feeders, and then, the transmission requests of terminal equipment in different areas to signals are met.

Further, in an embodiment, the wireless access point integrates a first power dividing circuit and a second power dividing circuit, the first network signal is split by the first power dividing circuit and then sent to the corresponding signal transceiver through the first feeder line, and the second network signal is split by the second power dividing circuit and then sent to the corresponding signal transceiver through the second feeder line in the same group. That is, the first network signal and the second network signal are sent to the same signal transceiver through different feeders after being branched, so that the signal transceiver sends different network signals to corresponding terminal devices. It can be understood that the network signal is shunted by the power dividing circuit, so that a single network signal can be respectively sent to the signal transceivers in different areas through different groups of feeders, and then different signal transceivers can send the network signal to different positions, thereby enlarging the coverage of the network signal.

For ease of understanding, as shown in fig. 2, taking a plurality of wards of a hospital as an example, each room may be respectively disposed with an independent signal transceiver, i.e., each room is disposed with a signal transceiver. When terminal devices located in the same room, for example, user mobile devices such as mobile phones and electronic medical devices in the room, initiate network requests to the same network end, for example, an external network, or to different network ends, for example, an internal network or an external network, a signal transceiver in the room sends network signals corresponding to different power distribution circuits in the wireless access point to corresponding terminal devices. Specifically, referring to fig. 2, for example, when a medical device located in a certain room requests a first network signal of an intranet, and a user mobile phone requests a second network signal of an extranet, a signal transceiver in the room sends the corresponding network signal to a corresponding terminal device through different feeders, that is, the first network signal from the intranet passes through a first power division circuit in a wireless access point and is sent to the signal transceiver through a first feeder, the signal transceiver forwards the first network signal to the medical device, the second network signal from the extranet passes through a second power division circuit in the wireless access point and is sent to the signal transceiver in the room through a second feeder, and the signal transceiver forwards the second network signal to the user mobile phone. On the contrary, when the user mobile phone requests the first network signal and the medical equipment requests the first network signal, the signal transceiver in the room transmits the corresponding network signal according to the path, and finally the signal transceiver sends the first network signal to the user mobile phone and sends the second network signal to the medical equipment. Similarly, when different terminal devices in other rooms request network signals required by the terminal devices, the network signals at different ends are shunted through the corresponding power dividing circuits and transmitted to the signal transceiver in the room through the corresponding feeder line in the same group of feeder lines, and the signal transceiver in the room sends the network signals to the corresponding terminal device.

In the design, network signals of different network ends are shunted through different power dividing circuits and are transmitted to the signal transceivers of corresponding rooms from different feeder lines, so that physical isolation among different network signals is realized, and network safety is ensured; meanwhile, the network signals after being branched are transmitted to the signal transceivers of the corresponding rooms through the corresponding feeders, so that network coverage of different areas, even room levels, can be realized, the stability of the signals of each area is ensured, the network architecture is simplified, and the network deployment cost is reduced; in addition, only one wireless access point is needed to be maintained, so that the daily maintenance efficiency is improved, and the maintenance cost is reduced.

This step S110 introduces the process of the network terminal sending the network signal to the signal transceiver, and the following steps introduce the process of the signal transceiver sending the terminal signal to the network terminal.

Step S120, receiving the terminal signal sent by the corresponding signal transceiver through different feeder lines in the same group, and sending the terminal signal to corresponding different network ends through different power dividing circuits.

It is understood that when the signal transceiver transmits the terminal signal to the network, the signal flow sequence of the above steps can be referred to for reverse transmission. Namely, the terminal equipment sends a terminal signal, and the signal transceiver receives the terminal signal; according to the network object requested by the terminal signal, namely the first network end or the second network end, the signal transceiver transmits the terminal signal to the corresponding power dividing circuit of the wireless access point along the first feeder line or the second feeder line, and finally reaches the corresponding network end. By the design, signal transmission between different network ends and the terminal equipment is realized only along the same network architecture, so that the overall architecture is simplified, and the physical isolation between an internal network and an external network is ensured by a shunt transmission mode, and the safety of the different network ends when being accessed by various terminal equipment is ensured.

It can be seen from this embodiment that, in the scheme of the present application, only one wireless access point needs to be set, so that network signals originating from different network ends can be shunted through respective corresponding power splitting circuits to obtain corresponding shunted signals, and the shunted signals of different network ends are physically isolated through respective corresponding feeder lines, thereby ensuring network security; in addition, the signal transceiver in the room division technology is used for stably and reliably transmitting the network signals after each branch in each different area, so that the room-level network signal coverage is realized, the number of wireless receiving points needing to be maintained is greatly reduced, and the maintenance cost and the network deployment cost are reduced.

Fig. 3 is a schematic flow chart of a network signal isolation transmission method shown in an embodiment of the present application, and in the embodiment, three different network ends, such as an internal network, an external network, and an internet of things, are deployed in the same scene, for example, a scene in which a hospital is located, so as to further introduce the network signal isolation transmission method of the present application.

Referring to fig. 3, an embodiment of the present application provides a network signal isolation transmission method, which includes:

step S210, respectively receiving a first network signal from the intranet terminal, a second network signal from the extranet terminal, and a third network signal from the internet of things terminal.

In the process that the wireless access point respectively receives a first network signal of a first network end, namely an internal network end, and a second network signal of a second network end, namely an external network end, a third network signal sent by a third network end can also be received; the third network terminal is an internet of things terminal. In this embodiment, the network deployment in the same scene in a hospital includes an intranet, an extranet, and an internet of things. The first network signal can be sent by an uplink device in an intranet, the second network signal can be sent by a controller of a wireless access point connected with an extranet, and the third network signal can be sent by an application server of the internet of things. Furthermore, the intranet terminal, the extranet terminal and the internet of things terminal are respectively connected to corresponding uplink radio frequency interfaces of the same wireless access point to receive the first network signal, the second network signal and the third network signal.

Step S220, combining the first network signals of different frequency bands, and/or combining the second network signals of different frequency bands; and combining the third network signal with the first network signal or the second network signal.

In one embodiment, network signals of different frequency bands in the same network signal are combined. It will be appreciated that the first network signals may comprise radio frequency signals in the 2.4G and 5G frequency bands, and the second network signals may also comprise radio frequency signals in the 2.4G and 5G frequency bands. Each frequency band is only for illustration and is not limited herein, and for example, the frequency band may further include a radio frequency signal in a 6G frequency band. In order to simplify the network structure, when the first network signal includes signals of different frequency bands, the signals of different frequency bands are combined in the wireless access point through the first combining circuit, and then subsequent steps are performed to perform signal power division. Similarly, for the second network signals of different frequency bands from the external network, the second network signals of different frequency bands are combined through the second combining circuit, and then the signal power division of the subsequent steps is performed. Different combining circuits are adopted to process signals of different frequency bands in the first network signal and signals of different frequency bands in the second network signal respectively, so that the first network signal and the second network signal can transmit signals of 2.4G frequency bands and 5G frequency bands, and the first network signal and the second network signal are not interfered with each other.

Further, the third network signal may also include radio frequency signals in 2.4G and 5G bands. The third network signal is combined with the first network signal or the second network signal and the frequency bands are staggered. The gateway board card of the internet of things is integrated in the wireless access point, so that the third network signal of the internet of things end can be combined with the first network signal or the second network signal. For example, the third network signal from the internet of things end and the second network signal from the external network end may be combined by the third combining circuit, so that the second network signal and the third network signal in the subsequent step share the same second power dividing circuit and the same second feeder line, thereby simplifying the wiring structure. The two network signals after being combined have the radio frequency interface and the feeder line of the wireless access point which are used together. In other embodiments, the third network signal from the internet of things end and the first network signal from the intranet end may also be combined by a third combining circuit, so that the first network signal and the third network signal in the subsequent step share the same first power dividing circuit and the same first feeder line. Further, by staggering the frequency bands of the network signals at two different ends, crosstalk of the two different network signals after combination is avoided, for example, when the third network signal is combined with the second network signal, the third network signal may select a 5G frequency band, and the second network signal may select a 2.4G frequency band.

Optionally, in order to ensure the signal strength of the split signal in the subsequent step, before splitting each network signal, the network signal is subjected to signal amplification, for example, the first network signal or the second network signal may be subjected to signal amplification in advance to make up for the signal strength loss of each signal in the subsequent transmission process. In this case, a signal amplifier, for example an active bidirectional amplifier, may be integrated into the radio transmission point, through which the first network signal or the second network signal is signal-amplified. In this embodiment, only the first network signal at the network end farther from the wireless transmission point, for example, the intranet end, may be subjected to signal amplification.

Step S230, obtaining a plurality of first branch signals from the first network signal through the first power dividing circuit; the second network signal is shunted through a second power shunt circuit to obtain a plurality of second shunt signals; and shunting the third network signal according to the corresponding first power division circuit or the second power division circuit to obtain a plurality of third shunting signals.

It can be understood that, if the third network signal is combined with the first network signal, the third network signal and the first network signal respectively obtain the first branch signal and the third branch signal through the first power dividing circuit. And if the third network signal and the second network signal are combined, the third network signal and the second network signal respectively obtain a second shunt signal and a third shunt signal through a second power shunt circuit.

The first power dividing circuit may divide the first network signal into N by 1, and the N first branch signals are led out from the N first radio frequency interfaces of the wireless access point. The second power dividing circuit divides the second network signal into M parts by 1, and the M parts of second branch signals are respectively led out from M second radio frequency interfaces of the wireless access point. N and M are natural numbers, and N and M may be the same or different. That is, each shunt signal corresponds to an independent rf interface, which is not interfered with each other, so as to realize physical isolation of different network signals. The third network signal is divided into P through the first power dividing circuit or the second power dividing circuit by 1, and P is a natural number. And P is equal to N or M, and P parts of third shunting signals are led out from the N first radio frequency interfaces or the M second radio frequency interfaces. That is to say, the same first radio frequency interface is adopted for the third shunt signal and the first shunt signal, or the same second radio frequency interface is adopted for the third shunt signal and the second shunt signal, so that the overall structure of the wireless access point is simplified.

Step S240, the first branch signal is transmitted to the signal transceiver through the first feeder line in the same group, the second branch signal is transmitted to the signal transceiver through the second feeder line in the same group, and the third branch signal is transmitted to the signal transceiver through the corresponding first feeder line or second feeder line in the same group, so that the first branch signal, the second branch signal, and the third branch signal are transmitted through the corresponding signal transceiver.

It will be appreciated that N and M may be the same or different, depending on the N first split signals and the M second split signals. N first feeder lines and M second feeder lines are respectively arranged, each first feeder line is connected with one of the N first radio frequency interfaces, and each second feeder line is connected with one of the M second radio frequency interfaces. Further, the number of signal transceivers is set according to the larger of N or M; the signal transceiver may be an antenna.

In conjunction with fig. 2 and 8, taking a hospital as an example, an indoor distribution system is provided in each building in the hospital, and signal transceivers, i.e., antennas, are respectively arranged in different locations, such as each room and/or corridor, so that the first branched signal, the second branched signal and the third branched signal are uniformly transmitted and distributed in each corner of the hospital through the antennas in different locations.

The above steps S210 to S240 are processes of processing and transmitting each received network signal to the signal transceiver by the wireless access point; the following steps S250 to S260 are processes in which the signal transceiver transmits the received terminal signal to the wireless access point for processing and then sends the processed terminal signal to each network. The process from step S210 to step S240 and the process from step S250 to step S260 may not be performed in sequence.

Step S250, receiving the terminal signal sent by the signal transceiver, and transmitting the terminal signal along the first feeder line or the second feeder line according to the network request in the terminal signal.

The signal transceiver transmits the first branch signal, the second branch signal and the third branch signal to the corresponding terminal devices, and meanwhile, the signal transceiver can also receive the terminal signals transmitted by each terminal device.

It is understood that the terminal-initiated network request may be a request for an intranet, an extranet, or an internet of things. And transmitting the terminal signals along different paths aiming at different types of network requests. For example, the terminal signal for the internal network is transmitted along a first feeder line, and the terminal signal for the external network is transmitted along a second feeder line. And if the Internet of things and the external network are combined in the steps, transmitting the terminal signal aiming at the Internet of things along the second feeder line.

Step S260, the terminal signal is sent to the intranet terminal, the extranet terminal or the internet of things terminal through the first power dividing circuit or the second power dividing circuit.

It can be understood that according to the path of the network signal transmitted to the signal transceiver in the above steps S210 to S240, the terminal signal is transmitted along the opposite direction of the path. If the network request object of the terminal signal is an intranet terminal, the network request object reaches a first radio frequency interface of a wireless access point through a first feeder line, enters a first power division circuit in the wireless access point, is subjected to signal enhancement through an active bidirectional signal amplifier, then passes through a first combining circuit, and finally reaches uplink equipment of the intranet terminal. If the network request object of the terminal signal is an external network end, the terminal signal reaches a second radio frequency interface of the wireless access point through a second feeder line, sequentially enters a second power division circuit and a second combining circuit in the wireless access point, and reaches a controller of the wireless access point for receiving processing. Similarly, if the network request object of the terminal signal is the internet of things end, the terminal signal reaches the first radio frequency interface or the second radio frequency interface corresponding to the wireless access point through the first feeder line or the second feeder line, returns to the gateway board card of the internet of things in the wireless access point through the first power dividing circuit or the second power dividing circuit and the third combining circuit, and finally is transmitted to the application server of the internet of things end after data processing is performed through the gateway board card of the internet of things.

As can be seen from this example, the network signal isolation transmission method of the present application implements wireless network dual-network physical isolation of an intranet and an extranet based on two sets of independent power division circuits and two independent first and second feeders built in a device of one wireless access point; in addition, the sharing of antennas can be realized through the shunt signals after different power division circuits, a network deployment structure is simplified, deployment cost is reduced, the internet of things can share the same signal transceiver together with the internal network and the external network, the signal transceivers can be distributed in different positions based on a room division technology, and signals of the internal network, the external network and the internet of things meet room-level coverage by transmitting the network signals through the signal transceivers in different positions.

Fig. 4 is a schematic flowchart of a network signal isolation transmission method between an internal network end, an external network end, an internet of things end, a wireless access point, an antenna, and a terminal according to an embodiment of the present application.
