Description

Technical Field

[0001] The utility model relates to the technical field of communications, and in particular to a room-based antenna monitoring device. Background Art

[0002] With the rapid increase of mobile users in cities and more and more high-rise buildings, the traffic density and coverage requirements are also rising. These buildings are large in scale and have a strong shielding effect on mobile phone signals. In the lower floors of large buildings, underground shopping malls, underground parking lots and other environments, the mobile communication signal is weak and the mobile phone cannot be used normally, forming a blind spot and shadow area for mobile communication; in the middle floors, due to the overlap of signals from different base stations around, pilot pollution is caused, and the mobile phone frequently switches, and even drops calls, which seriously affects the normal use of the mobile phone. In addition, in some buildings, although the mobile phone can talk normally, the user density is high, the base station channel is crowded, and it is difficult for the mobile phone to go online. The above problems can be solved to a certain extent by setting up an indoor distribution system. The indoor distribution system consists of a communication signal transmitting device and an antenna network. The principle is to use the indoor distribution system to evenly distribute the signal of the mobile communication base station in every corner of the room, so as to ensure that the indoor area has ideal signal coverage. However, the indoor distribution system of telecom operators is often damaged by lines due to various reasons, resulting in some antennas not working properly or not working. Currently, detection in this regard mainly relies on signal strength feedback from the base station signal transmission system or manual inspections to detect whether the antenna is working properly. However, the results of the above detection methods are often not accurate enough, and the cost of obtaining the results using this method is very high.

[0003] Chinese patent document CN110266404A discloses "an indoor distributed antenna detection system and method". An antenna network is adopted, which includes a plurality of antenna terminals, each antenna terminal is pre-arranged with an electronic tag, and each electronic tag has its unique identification code; a communication signal transmitting device, which is used to transmit the communication signal of the telecommunications operator; a detection signal transmitting device, which is used to transmit a detection radio frequency signal according to a control instruction to read the identification code of the electronic tag of each antenna terminal; a switching device, whose first input end is connected to the communication signal transmitting device, whose second input end is connected to the detection signal transmitting device, and whose output end is connected to the input end of the antenna network, is used to switch the communication signal transmitting device or the detection signal transmitting device to access the input end of the antenna network according to a driving signal; a control device, which is respectively connected to the control end and the detection signal transmitting device of the switching device, is used to output the driving signal when receiving the switching instruction so that the detection signal transmitting device is connected to the input end of the antenna network and issue the control instruction, and detect the access status of each antenna terminal by comparing the identification code of each pre-stored electronic tag with the identification code of each read electronic tag. However, the patented indoor antenna system cannot accurately monitor and cannot achieve full-band signal coverage. Summary of the invention

[0004] The utility model mainly solves the technical problem that the original working status of the indoor antenna cannot be accurately monitored, and provides a indoor antenna monitoring device.

[0020] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0021] Embodiment: A room-based antenna monitoring device according to this embodiment, such as Figure 1 and Figure 2As shown, it includes an antenna detection box, a mobile terminal, and a room antenna monitoring part. In order to improve the signal strength of the communication signal when it is transmitted in the building, an indoor distribution system (hereinafter referred to as the room antenna system) is generally set up in the building. The indoor distribution system is mainly used to improve the mobile communication environment in the building. Its principle is to use the indoor antenna distribution system to evenly distribute the signal of the mobile communication base station to every corner of the room, thereby ensuring the ideal signal coverage of the indoor area. However, there are several problems in the operation and management of the room distribution system: First, the room distribution system lacks a remote monitoring method, and it is basically a hidden system. After it is put into use, there is no way to perform open maintenance, let alone daily maintenance support and fault handling and positioning; second, the fault information operator of the room distribution system cannot obtain the alarm status in the first time, and it can only be reflected after the user complains; third, there is a lack of asset monitoring means for man-made secondary decoration damage, theft damage and aging of devices; fourth, there is a lack of effective measurement methods for network signal quality. The above four problems will lead to the fact that when a large number of indoor antenna systems distributed in the building fail, maintenance personnel will not be able to accurately locate the fault point in time for maintenance, or will not be able to clearly identify the type of problem in the indoor antenna system. This will cause maintenance personnel to carry as many maintenance tools as possible to deal with unknown problems, greatly increasing the cost of manpower and material resources. At the same time, the indoor antenna system cannot be managed and maintained in a timely manner during daily operation, and frequent and unreasonable losses will also increase the cost burden. In order to solve the above problems, the existing implementation solution MIOTSS is a link detection system based on RFID ultra-high frequency (UHF), but it can only monitor the line connection and disconnection in the antenna feed system, and cannot detect the working conditions of the signal source and RRU in the entire indoor system. If professional instruments are used for signal measurement, there are the following disadvantages: (1) The cost is too high, generally costing tens of thousands or hundreds of thousands of yuan; (2) The size is large and the weight is heavy, which is not easy to carry and move; (3) The power supply method is limited, generally requiring an external power supply or battery; (4) The operation is complicated and requires professional personnel to set up and debug. However, using only mobile device terminals for signal measurement has the following disadvantages: (1) Limited by the frequency band range supported by the terminal, it cannot cover the entire frequency band; (2) Limited by the hardware performance of the terminal, it cannot achieve high-precision and high-speed measurement; (3) Limited by the software functions of the terminal, it cannot achieve the generation and analysis of multiple signals; (4) Limited by the security of the terminal, there may be a risk of data leakage or tampering. In order to simultaneously take into account the monitoring cost, range and accuracy, this embodiment provides a room-based antenna monitoring device to achieve the measurement, analysis and monitoring of 4G / 5G cellular full-band signals, solve the current operational management defects of the room-based system, and achieve the management goals of data association, on-site maintenance and remote monitoring.In this embodiment, the indoor antenna device is provided with an indoor antenna part and an indoor antenna monitoring part, and the antenna detection box is arranged between the indoor antenna part and the indoor antenna monitoring part, and the indoor antenna monitoring part includes a presentation layer, a platform layer, a gateway layer and a business layer, and a gateway layer and a business layer are arranged between the presentation layer and the platform layer, and the presentation layer is respectively connected to the mobile terminal and the gateway layer, and the indoor antenna monitoring part is provided with a cloud, and the platform layer is respectively connected to the cloud and the indoor signal monitoring platform for data exchange. The gateway layer is respectively connected to the presentation layer and the business layer. The indoor antenna monitoring part is also connected to the mobile terminal, and the antenna detection box arranged next to the indoor antenna includes an upper shell and a base, and the power supply module and the control circuit module are arranged between the upper shell and the base, and a plurality of base fixing holes are dug on the edge of the base, between the upper shell and the base. An empty groove is arranged in the middle of the base, and an empty groove is arranged on the edge of the empty groove, and a sealing ring is arranged in the empty groove. The antenna detection box includes a shell and an antenna end, and the antenna end is arranged at one end of the shell. The antenna detection box also includes a detection module, and the detection module is connected to the indoor antenna. The antenna end also includes an antenna bracket, which includes a supporting plane and a fixed end. A fixed end is provided on one side of the supporting plane, and a fixing hole is provided on the fixed end. An anti-slip end is provided on the other side of the supporting plane. The anti-slip end is curved upward in an arc shape, and a notch is provided in the center of the anti-slip end. The detection box device in the indoor antenna monitoring system is used to realize signal measurement, which can cover a variety of frequency bands and standards, and has the characteristics of low cost, small size, and strong function. The antenna detection box is directly connected to the indoor antenna system and the indoor antenna monitoring part. After the detection module is connected to the indoor antenna system, it can directly detect the conditions of different antennas in the system and directly feed back the detected antenna status in the form of data to the indoor antenna monitoring part, thereby improving the efficiency of subsequent platform processing and analysis of antenna status. The indoor signal monitoring platform is used to realize signal analysis and monitoring. The platform adopts a microservice architecture, which can be divided into a presentation layer, a gateway layer, a business layer, and a platform layer from top to bottom. The presentation layer is the client tool for interaction between users and the system, which includes WEB and mobile terminals; the gateway layer serves as a bridge for communication between the presentation layer and system services. The services of the gateway layer can log in / authenticate user identities, forward Http requests to corresponding system services through routing, and ensure high availability of system services through load balancing, fuse degradation and other traffic control strategies; the business layer is responsible for implementing specific business needs; the platform layer serves as a bridge for data interaction between devices and the cloud. In this embodiment, the indoor antenna monitoring part uses the IOT platform to provide basic device access services.In order to facilitate installation and maintenance when problems occur with the indoor antenna, after the layout of the indoor antenna is installed in a certain space, the number and location of the antenna detection boxes to be installed are determined according to the specific distribution of the indoor antennas. After the location is planned, the antenna bracket is installed at the determined location. The antenna bracket is fixed at the fixed end and the matching fixings are used to ensure that it is stably positioned at the specified position. The shell of the antenna detection box is then installed on the supporting plane of the antenna bracket. The detection box can be installed indoors using the antenna bracket. In order to ensure long-term and stable use of the antenna detection box and to prevent the antenna detection box from sliding and causing damage to the shell itself, thereby affecting the service life of the antenna detection box, a fixed end is provided on one end of the antenna bracket in this embodiment, and a fixing hole that matches the antenna detection box is provided on the fixed end. The fixing nut is passed through the fixing hole on the fixed end on one side of the supporting plane to fix the entire antenna bracket and the shell of the antenna detection box indoors. At the same time, in order to prevent the antenna detection box shell from sliding off the antenna bracket, an anti-slip end that is curved upward in an arc shape is provided on the other side of the antenna bracket support plane in this embodiment. After the antenna detection box shell is installed on the support surface, the anti-slip end can hook and support the shell of the antenna detection box through the curved part of the arc shape, ensuring that the indoor antenna will not slide off and the antenna detection box can be stably mounted on the support surface for operation. When the antenna detection box is working, the detection module in the shell can provide real-time feedback on the real-time situation of the indoor antenna part detected by the antenna detection box, and feedback the situation to the indoor antenna monitoring part in real time.

[0022] The specific steps of the indoor antenna monitoring part in actual use in this embodiment are as follows: first, perform the initial installation, assemble and link the various parts. During installation, the corresponding indoor antenna needs to be started first, and then the antenna detection box is triggered to trigger the work. The antenna detection box has a self-learning mechanism during operation: the antenna detection box starts automatically after being triggered, and the detection after successful learning will continue to use the results of the previous learning. After the antenna detection box detects whether there is a 4G LTE signal and the corresponding Band, the base station is connected through the existing network provided by the mushroom head and the downlink frequency, physical CELL ID, downlink signal strength, signal-to-noise ratio and other parameters are obtained and reported to the cloud. When 4G LTE cannot be detected, the frequency scanning mechanism of the 5G NR frequency band is turned on. After the scan is successful, the downlink frequency and signal strength are reported to the cloud. After the preconditions are completed, the mobile operator will bind the operation and maintenance APP: enter the antenna number information and scan the ID QR code of the antenna detection box for cloud binding. After the platform is successfully bound, the self-learning information reported by the antenna box includes the downlink frequency, physical CELL ID, downlink signal strength, signal-to-noise ratio, and binding information reported by the operation and maintenance. Finally, a successful binding decision is made and returned to the operation and maintenance APP. The normal detection process of the indoor signal monitoring platform in this embodiment is as follows: After a detection cycle (the default is 1 day, which can be configured in batches through the platform), the antenna detection box wakes up from the sleep state to detect the signal. After the detection is successful, the necessary indoor antenna health information is reported. Determine whether to generate an alarm based on the detected information. The alarm levels are level 1 alarm, level 2 alarm, and level 3 alarm. If the antenna monitoring frequency band is completely lost or the signal is abnormal (RSRP is too low), the cause of the alarm is a broken link alarm, and the indoor antenna monitoring part will generate a first-level alarm; if the reported frequency band is compared with the monitoring frequency band, the reported frequency band contains a new frequency band whose RSRP is greater than the threshold (-70db), and the antenna is not in the self-learning cycle, the cause of the alarm is a new frequency band alarm, and the indoor antenna monitoring part will generate a second-level alarm; if the antenna monitoring frequency band is partially lost, the cause of the alarm is a lost frequency band alarm, and the indoor antenna monitoring part will generate a third-level alarm; if the RSRP of the antenna monitoring frequency band is partially too low, the cause of the alarm is a low RSRP alarm, and the indoor antenna monitoring part will generate a third-level alarm. The indoor antenna monitoring part in this embodiment can take into account both the convenience of installation and the alarm mechanism, and can also improve the comprehensiveness of the monitoring of the indoor antenna system.
