Problems solved by technology

However, with the completion and operation of a large number of indoor coverage systems, the method of manual inspection of indoor coverage systems has the following problems: the workload of dialing and testing is heavy and the cost is high; the frequency of dialing and testing is low—once a month, not timely The problem was found; there are generally dozens or even hundreds of antennas in the indoor coverage system. During the dial-up test, the maintenance personnel usually only test the signals of one or two antennas in the system, and will not test the signals of all the antennas. If the indoor coverage system Only part of the area is faulty, and the inspection personnel will probably not find the fault
In this way, due to the addition of connectors and other accessories, the cost of a single monitor is higher, even higher than the price of the antenna
Moreover, the implementation of this method needs to disconnect the antenna feeder, which is inconvenient for construction.

Embodiment 1

[0030] Such as figure 1 As shown, the existing indoor distribution system includes BTS, the first indoor antenna individual, the second indoor antenna individual, the third indoor antenna individual, etc. The main feeder of the indoor antenna output by the BTS passes through the indoor distribution network and is branched into the feeder of each indoor antenna individual .

[0031] In order to realize the remote monitoring of individual indoor antennas of the indoor distribution system of mobile communication, the following methods are adopted:

[0032] 1) Fix a radio frequency tag at a distance of 0.3m from the radiator of the individual indoor antenna; the radio frequency tag includes a unique address number in the local monitoring system, which has been determined when the radio frequency tag is produced. The electrical performance specifications of the radio frequency tag match the electromagnetic radiation performance of the indoor antenna individual, and can use the sig...

Embodiment 2

[0037] The difference between this embodiment and embodiment 1 is:

[0038] a) When the individual indoor antenna leaves the factory, a radio frequency tag has been fixed inside the housing.

[0039] b) After the radio frequency tag is activated, the information sent also includes the voltage value when it is activated.

[0040] c) Data communication between the reading transponder and the remote computer through a wired broadband network.

[0041] d) The monitoring software takes the following condition as an alarm condition: the difference between the activation intensity value of the current radio frequency tag and the reference value set for the radio frequency tag exceeds a preset range.

[0042] For example: for the first indoor antenna individual, set its reference value to 0.1 volts in the monitoring software, and set the difference between the activation strength value and the reference value to not exceed 30% of the reference value; for the second indoor antenna ind...

Abstract

The invention provides a method of remote control of an indoor antenna individual body so that working conditions of each indoor antenna can be obtained rapidly. The mobile communication indoor distribution system device remote control method comprises the following steps: fixing a radio frequency tag near the indoor antenna individual body; setting a coupler on an indoor antenna main feeder of a base transceiver station (BTS); setting a reading transponder communicated with the coupler; and setting monitoring software on a computer. The radio frequency tag uses electromagnetic radiation energy of the indoor antenna individual body to activate and send an address code of the indoor antenna individual body, therefore the monitoring software can monitor the working conditions of all radio frequency tags in a system according to preset alarm conditions, and then the working conditions of the indoor antenna individual body are monitored. The mobile communication indoor distribution system device remote control method has the advantages of being rapid in finding and positioning of failures, free from wire arrangement, low in cost and the like.

Description

technical field [0001] The invention relates to a monitoring method for monitoring the operating state of an indoor antenna of a mobile communication system. Background technique [0002] Except for the signal source, the indoor coverage system of mobile communication is passive devices, such as power dividers, combiners, radio frequency cables, indoor antennas, etc. Currently, operators monitor the equipment in the indoor distribution system in the following ways: [0003] 1. Use the method of manual dialing test. However, with the completion and operation of a large number of indoor coverage systems, the method of manual inspection of indoor coverage systems has the following problems: the workload of dialing and testing is heavy and the cost is high; the frequency of dialing and testing is low - once a month, and cannot be timely The problem was found; there are generally dozens or even hundreds of antennas in the indoor coverage system. During the dial-up test, the mai...
