Description

Technical Field

[0001] The utility model relates to an in-building network monitoring system and method based on a mixed beacon of a wireless communication protocol, which is applied to an in-building antenna system in the field of mobile communication. The in-building antenna system (DAS) mainly solves the indoor mobile signal coverage scenario. Background Technique

[0002] A distributed antenna system (DAS) refers to a group of geographically or structurally separated antenna nodes that are connected to a common signal source through a transmission medium to provide wireless services. DAS can be flexibly deployed in indoor (iDAS) or outdoor (oDAS) environments. The core idea of DAS is to disperse the transmission power to multiple antenna units to cover the same area as a single antenna, while reducing the total power consumption and improving the system reliability.

[0003] There are two problems with the existing DAS system: 1. It is impossible to monitor the chain loss changes of antennas and feeders. Since the installation of the in-building system is complex and the initial installation workload is very large, including the installation of various feed lines and radio frequency devices, etc., the construction professionalism is high. After the system is delivered for use, due to various reasons, the lines age, are damaged, or even destroyed, resulting in abnormal link losses. In this case, it is very difficult to detect from the system end. Usually, it is through the patrol inspection of operation and maintenance or receiving customer complaints, and then going to troubleshoot. It is very difficult to achieve pre-judgment. 2. It is impossible to monitor the actual signal quality changes of operators in real time. When an in-building system is installed, due to such reasons, the signal quality in a certain area will change. The reasons may come from changes in the external environment or signal abnormalities of the base station itself, etc. Therefore, it is necessary to detect the signal changes in the area in real time and handle them accordingly. Content of the Utility Model

[0004] Generally speaking, the technical problem to be solved by the utility model is to provide an in-building network monitoring system and method based on a mixed beacon of a wireless communication protocol, which is used to monitor the link loss of the DAS system, monitor the mobile signal quality in a fixed area, and provide some vertical applications based on Bluetooth, 4G, and / or 5G wireless communication protocols.

[0005] To solve the above problems, the technical solutions adopted by the utility model are as follows:

[0006] In order to simplify the structure and reduce the initial installation quantity, an in-building network monitoring system based on a mixed beacon of a wireless communication protocol includes a beacon module. The beacon module includes a 4G / 5G module, a temperature and humidity sensor, a Bluetooth chip, a two-way power splitter or an antenna switch, and a Bluetooth antenna; the Bluetooth antenna includes a Bluetooth directional antenna and a Bluetooth beacon antenna;

[0007] The Bluetooth chip is respectively communicatively connected to the 4G / 5G module and the temperature and humidity sensor;

[0008] The Bluetooth chip is connected to the Bluetooth directional antenna and the Bluetooth beacon antenna respectively through a two-way power splitter or an antenna switch.

[0009] The Bluetooth chip is electrically connected to the power supply module.

[0010] The 4G / 5G module is connected to a 4G / 5G antenna.

[0011] As a further improvement of the above technical solution:

[0012] To adapt to the power supply in multiple scenarios, the power supply module includes a lithium battery and / or a power chip connected to a DC power supply interface.

[0013] To achieve clock correction, the Bluetooth chip is electrically connected to a timer.

[0014] To achieve mobile communication and data collection, the 4G and / or 5G antenna is used to detect the signal quality and signal stability of surrounding operators.

[0015] The temperature and humidity sensor is used to monitor the surrounding environment.

[0016] The Bluetooth beacon antenna is used to obtain the Bluetooth position, and the radiation direction is perpendicular to the ground.

[0017] The Bluetooth directional antenna is equipped with a distributed antenna for in-building coverage to cooperate for link loss detection, and the radiation direction is aligned with the distributed antenna for in-building coverage.

[0018] To achieve the processing of the collected information, the beacon module corresponds to a Bluetooth gateway; the beacon module is located at the end of the feeder cable, and the front end of the feeder cable is electrically connected to the Bluetooth gateway and the operator signal module respectively through a Bluetooth combiner.

[0019] The Bluetooth gateway has an information processing unit and a Bluetooth transceiver module connected for communication; the information processing unit includes a Bluetooth board, an ARM board, and an RJ45 interface connected in sequence; the Bluetooth board is connected to the Bluetooth combiner; the ARM board is connected to the Bluetooth transceiver module.

[0020] The Bluetooth transceiver module includes a 4G and / or a wifi transceiver.

[0021] There is an antenna cover at the back end of the feeder cable corresponding to the Bluetooth directional antenna.

[0022] To achieve data storage, the Bluetooth gateway is connected to the background server.

[0023] The background server includes a message transceiver module, a database unit, and a display unit connected for data.

[0024] The Bluetooth gateway processes the data and then connects to the beacon module.

[0025] In order to achieve coordination between modules, in the beacon module, when the set time is reached, the Bluetooth chip is in the awake state, the temperature and humidity sensor and the 4G / 5G module are in the working state, and data is collected and output to the information processing unit.

[0026] In order to solve the technical problem of the utility model, a room-divided network monitoring method based on a hybrid beacon of a wireless communication protocol is provided, with the aid of the above-mentioned room-divided network monitoring system;

[0027] Perform the following steps; first, start the timer to cycle, and then wake up the Bluetooth chip when the set time is up; second, start the temperature and humidity sensor to collect temperature and humidity data and output it to the information processing unit, collect mobile signal data through the 4G / 5G module and output it to the information processing unit, obtain the Bluetooth position through the Bluetooth beacon antenna and output it to the information processing unit, and perform link loss detection through the Bluetooth directional antenna and the indoor antenna and output it to the information processing unit; the information processing unit processes the information, and the Bluetooth transceiver module sends the processed information to the background server, and the data is stored and displayed on the server the day after tomorrow.

[0028] Among them, the DAS monitoring system already exists. The first generation of indoor monitoring networks based on RFID technology can only monitor link loss. The second generation, indoor monitoring networks based on Bluetooth, can not only perform link loss detection but also have many Bluetooth-related vertical application scenarios. The most critical difference between the second generation system and the utility model is that the second generation system needs to install the Bluetooth module inside the indoor antenna to form a dedicated indoor antenna with Bluetooth in order to solve the link loss accuracy problem. However, this design seriously affects the transformation of the existing network.

[0029] The utility model adopts directional antennas and aligns them with indoor antenna installation to ensure that the link loss accuracy is not affected. There is no need to use dedicated indoor antennas, which greatly improves the flexibility and feasibility of existing network transformation. By adding 4G / 5G modules, the signal monitoring capability of surrounding networks is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] like Figures 1-3, this system is introduced in three parts: Bluetooth, 4G and / or 5G communication module beacon, where 4G / 5G means 4G and / or 5G; this is the most core part of the present utility model. The beacon module includes a 4G / 5G module, a temperature and humidity sensor, a Bluetooth chip, a two-way power splitter or an antenna switch, a Bluetooth directional antenna, and a Bluetooth beacon antenna;

[0034] The Bluetooth chip is respectively communicatively connected to the 4G / 5G module and the temperature and humidity sensor;

[0035] The Bluetooth chip is respectively connected to the Bluetooth directional antenna and the Bluetooth beacon antenna through a two-way power splitter or an antenna switch;

[0036] The Bluetooth chip is electrically connected to the power supply module;

[0037] The power supply module includes a lithium battery and / or a power supply chip connected with a DC power supply interface;

[0038] The 4G / 5G module is connected with a 4G / 5G antenna;

[0039] The Bluetooth chip is electrically connected to a timer;

[0040] Its beacon designed based on a low-power Bluetooth chip + 4G and / or 5G chip has standard 4G and / or 5G antennas for detecting the signal quality and signal stability of surrounding operators.

[0041] The temperature and humidity sensor is used to monitor the surrounding environment.

[0042] There are two types of Bluetooth antennas, namely beacon antenna and directional antenna. Among them, the beacon antenna is used for applications such as Bluetooth location services, and its radiation direction is usually perpendicular to the ground. The directional antenna is used to cooperate with the in-building distribution antenna for link loss detection, and its radiation direction is aligned with the in-building distribution antenna.

[0043] There are two power supply methods. External DC power supply can be used in various scenarios without power consumption problems. Built-in large-capacity lithium batteries are generally used in low-power scenarios.

[0044] Such as Figure 2 , the topological relationship between the Bluetooth gateway and the beacon. The beacon module corresponds to a Bluetooth gateway; the beacon module is located at the end of the feeder cable, and the front end of the feeder cable is respectively electrically connected to the Bluetooth gateway and the operator signal module through a Bluetooth combiner;

[0045] The Bluetooth gateway has an information processing unit; the information processing unit includes a Bluetooth board, an ARM board, and an RJ45 interface that are sequentially electrically connected; the Bluetooth board is connected to the Bluetooth combiner; the ARM board is connected to the Bluetooth transceiver module; the Bluetooth transceiver module includes a 4G and / or wifi transceiver end;

[0046] There is an antenna cover at the back end of the feeder cable, corresponding to the Bluetooth directional antenna;

[0047] Near the indoor distribution antenna, the Bluetooth gateway includes a Bluetooth board for Bluetooth communication with beacons and link loss detection. The Bluetooth gateway sorts out various information obtained by the Bluetooth beacons and transmits it to the background service program via wired or wireless means.

[0048] As a further improvement, as Figure 3 The front-end and back-end internal processing architecture is divided into three parts: the back-end server, the Bluetooth gateway, and the beacon module, which respectively perform the work of collection - sorting - analysis and summary. The Bluetooth gateway is connected to the back-end server;

[0049] The back-end server includes a message transceiver module for data connection, a database unit, and a display unit; the program makes a total judgment on the information, outputs normal or abnormal alarm information, and forms a chain interaction.

[0050] The Bluetooth gateway has the above-mentioned information processing unit and a Bluetooth transceiver module for communicating with the message transceiver module, and connects to the beacon module after data processing;

[0051] The beacon module starts a timer to loop. When the set time arrives, it wakes up the Bluetooth chip; it starts the temperature and humidity sensor and the 4G / 5G module to collect data and output it to the information processing unit; it detects whether the communication link loss detection is normal and performs Bluetooth broadcasting.

[0052] The innovation point of the present utility model is to creatively move the Bluetooth module from inside the antenna to the outside.

[0053] In the current second-generation indoor distribution antenna detection system, due to the need to replace the new antenna type, the complexity is increased and the cost is very high. Therefore, it is difficult to be used for large-scale in-network upgrade and transformation, and the application scope is limited. Secondly, since the Bluetooth detection module is located at the antenna feeder inlet inside the indoor distribution antenna and uses the conduction mode to detect the feeder loss, it is impossible to detect the abnormality of the antenna element (i.e., the antenna body), resulting in a decrease in detection ability. In addition, the built-in Bluetooth module results in poor function expansion ability.

[0054] The present utility model changes the concept of the existing technology and moves the Bluetooth module outside. It can not only solve the problem of link loss detection for the entire link, but also cancel the dedicated antenna, which can not only reduce the cost, but also be directly used for in-network transformation, and the application scenario is greatly improved. By adding a 4 / 5G module and a temperature and humidity sensor, the detection ability is further expanded.

[0055] When the Bluetooth is moved outside, the problem of link loss detection accuracy needs to be solved. When it is built-in, the conduction method is adopted and the electromagnetic environment is relatively simple, so the stability and consistency are relatively good. After it is changed to be external, radiation is introduced, so it becomes very important to stably and reliably solve this air path problem. First, the beacon installation position is unified. An installation bracket is used and it is close to the antenna body, with a distance of about 0.5 meters and the height is flush with the radome. Second, the Bluetooth directional ceramic antenna is aligned with the side of the plastic outer cover of the indoor distribution antenna. Since the radiation angle of the Bluetooth directional ceramic antenna can reach 70 - 90 degrees, it has strong directivity and very strong anti-interference ability. It can ensure the reliability and stability of this radiation path.
