Description
Technical Field
The invention relates to the technical field of wireless communication, in particular to a portable method and a system for checking and accepting and polling a room.
Background
With the rapid development of mobile communication networks, the coverage requirement and reliability requirement of customers on mobile communication signals are increasingly increased, and especially the requirement on the reliability of the networks is higher in public safety network coverage. When mobile communication signal coverage is carried out, although the mobile communication network already realizes the monitoring function of active equipment, the monitoring is still stranded for a passive antenna feeder distribution system with 90% investment, and the fault can be known only by waiting for customer complaints without delay, and can not be actively identified and eliminated in advance, so that the improvement of customer satisfaction is greatly influenced. The traditional chamber has the prominent quality problem, and the system is unmanageable and uncontrollable. In field research, a large number of phenomena of poor coverage due to device problems have been found. Therefore, operators need a large amount of manpower and pay expensive labor cost to manually inspect each site every year, the manual inspection is still on the spot when the property coordination is difficult, the effect is very little, and the problems of failure, aging and the like of passive devices are increased along with the long-term maintenance. The RFID indoor branch monitoring system mainly realizes on-off monitoring of indoor branch circuits, data are returned through RFID labels, branch circuit loss is judged after a reader-writer receives the data, line loss values of the branch circuits are reported to a server, and the server directly presents the line loss to represent the quality of the branch circuits. Usually, through a reported data table, the line loss of each antenna point location is manually checked, and an alarm mechanism is set to check whether a branch has a broken circuit or an ultrahigh line loss. Currently, an indoor distribution system carries most telephone traffic of a mobile communication network, and a situation that a multi-system network (for example, GSM, DCS, TD, LTE, WLAN, etc. by taking china mobile as an example) shares the same antenna feeder distribution system in the same indoor distribution system point is more and more common. Therefore, indoor distribution systems have been placed in a very important position in the field of mobile communications. However, the indoor distribution system has been put into operation for more than ten years, during which time, each operator performs reciprocating construction (the antenna feeder wiring paths of each operator in the indoor distribution system are basically the same), the information source equipment, the antenna feeder and the passive devices are aged, and the owner unit repeatedly decorates and changes the lines, so that various chaotic situations occur in the indoor distribution system, so that faults frequently occur, network quality which cannot be directly perceived by users such as conversation, call drop and the like is caused, and customer complaints are high. At present, the fault is mainly passively discovered through user complaints and manual inspection, active real-time monitoring is difficult, and finally the user complaints in a coverage area are caused. Active equipment in the current mobile network completely has a monitoring function, but an indoor distribution system occupying a large investment share is still in an out-of-control state, a fault of a current indoor distribution monitoring system can only passively wait for customer complaints, but fault positioning is also complicated, and for large buildings, fault processing time can be greatly prolonged, so that the satisfaction degree of customers is greatly influenced.
However, the following schemes are available for the problem of monitoring the indoor antenna system:
the first solution is as follows: the far-end detection system of the indoor antenna system comprises a far-end antenna feeder system information acquisition center, a near-end monitoring center and a network management center; the remote antenna feed system information acquisition center comprises a radio frequency unit, a multi-frequency combiner, a room antenna and an RFID label; the acquisition terminal reads the serial number of the electronic tag attached to the antenna at regular time; each acquisition center is responsible for acquiring and monitoring fault data of the antenna feeder system, and all the acquisition centers send the acquired fault data and the topological structure data of the antenna feeder subsystem to the monitoring center; the network management center is used for receiving and processing the wireless information of the monitoring center and displaying the alarm. This solution has the following drawbacks: the monitoring system needs to replace customized antennas, and a remote system acquisition center needs to be installed on each antenna, so that the monitoring system is not convenient and fast due to the fact that hardware cost is consumed.
The second solution is as follows: radio frequency identification RFID card reader, combiner, attenuator and indoor branch antenna, wherein, RFID card reader with the combiner electricity is connected, the combiner pass through indoor branch system feeder network with indoor branch antenna connection: the RFID card reader is also connected with the indoor antenna through the attenuator; the combiner is also connected with the base station, receives the output signal of the base station, combines the output signal of the base station with the output signal of the RFID card reader, and sends the combined signal to the indoor branch antenna through an indoor branch system feeder network: and the RFID card reader sends an output signal to the indoor antenna through the attenuator. And calculating the path loss of the indoor branch antenna used in the branch circuit connected with the feeder network of the indoor branch system by continuously increasing the output power of the RFID card reader. The feeder network of the indoor distribution system can be connected with a plurality of indoor distribution antennas and can detect the path loss of each branch where the indoor distribution antennas are located. The scheme has the following disadvantages: each card reader needs one more port to access one attenuator and is connected with the indoor branch antenna, and the loss degree of the RFID tags connected to the tail ends of the indoor branch antennas on the two ports of the card reader is different, so that the final estimation result is inaccurate.
Therefore, the invention provides a portable room branch checking and inspection system, which has the characteristics of convenience in carrying, strong mobility, rechargeable performance and the like, can be used for inspecting the room branch system in real time by a portable room branch checking and inspection terminal system, is convenient for maintenance personnel to use as a test instrument, directly detects a link, inspects the working state of equipment on the link, realizes the detection of a plurality of room branch links of one set of inspection terminal system, and realizes real-time monitoring through a supervision cloud platform.
