Monitoring equipment and application method thereof

Abstract

The invention relates to the field of communication, and discloses monitoring equipment and an application method thereof, which are used for accurately positioning terminals in a 3rd-generation (3G) communication system and simultaneously avoiding the increasing of operating complexity. The monitoring equipment comprises smart antennae, a radio frequency switch and a monitoring receiver, wherein the monitoring receiver controls the radio frequency switch to sequentially receive terminal signals from each smart antenna according to a preset time sequence, and performs phase measurement positioning on corresponding terminals according to the terminal signals received from each smart antenna. Therefore, 3G phase measurement positioning work can be finished only by using a single-channel monitoring receiver, the terminals can be accurately positioned in the 3G communication system, the execution complexity of a phase measurement positioning algorithm is prevented from being increased, the power consumption of the monitoring equipment is prevented from being increased and the production cost of the monitoring equipment is ensured to be within an ideal range.

Description

technical field [0001] The invention relates to the communication field, in particular to a listening and monitoring device and an application method thereof. Background technique [0002] The terminal positioning and phase measurement functions are an important application of monitoring equipment (also called positioning phase measurement equipment). In the 2G communication era, different terminals occupy different frequency resources. The monitoring and monitoring equipment can distinguish different terminals by frequency. The phase detection antenna can be used to complete the identification of the terminal position, and then the target can be captured by gradually approaching. However, in the 3G communication system, the modulation method adopts CDMA (Code Division Multiple Access, Code Division Multiple Access) technology, and uses spreading codes to distinguish different terminal users, and different terminals are likely to work on the same frequency , therefore, the ...

AI Technical Summary

Problems solved by technology

However, there are 8 receiving links in the 8-channel receiver, which objectively increases the production cost of the monitoring equipment, and the existing single-channel monitoring receiver cannot be reused, which causes a waste of equipment resources to a certain extent

Moreover, the increase in the number of channels also brings about an increase in size and power consumption, which does not meet the portability requirements of monitoring and monitoring equipment.
