Problems solved by technology

[0004] However, the indoor distribution system of telecom operators is often damaged by secondary decoration or rodent infestation, resulting in some antennas not working properly or not working
At present, the signal strength feedback of the base station signal transmission system or manual inspection and other unreliable methods are mainly used to detect whether the antenna is working normally. The results are often inaccurate and the cost is high.

Abstract

The invention discloses an indoor distributed antenna detection system and method. The detection system comprises: an antenna network, wherein each antenna terminal is provided with an electronic tag in advance; a communication signal transmitting device which is used for transmitting a communication signal of a telecom operator; a detection signal transmitting device which is used for transmitting a detection radio frequency signal according to the control instruction to read the identification code of the electronic tag of each antenna terminal; a switching device which is used for switching the communication signal transmitting device or the detection signal transmitting device to be accessed to the input end of the antenna network according to the driving signal; and a control device which is used for outputting a 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 sends out a control instruction, and the access condition of each antenna terminal is detected by comparing the pre-stored identification code of each electronic tag with the read identification code of each electronic tag. The detection result of the indoor distributed antenna is high in accuracy and low in cost.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an indoor distributed antenna detection system and method. Background technique [0002] With the rapid increase of mobile users and more and more high-rise buildings in cities, the traffic density and coverage requirements are also rising. These buildings are large in size and have a strong shielding effect on mobile phone signals. In the environment of low floors of large buildings, underground shopping malls, underground parking lots, etc., the mobile communication signal is weak, and the mobile phone cannot be used normally, forming a blind area and shadow area of ​​mobile communication; on the middle floor, due to the overlapping of signals from different surrounding base stations, Cause pilot pollution, frequent switching of mobile phones, and even dropped calls, seriously affecting the normal use of mobile phones. In addition, in some buildings, although the mobil...
