Multi-channel networking test device for directional communication system

Abstract

The invention provides a multi-channel networking test device of a directional communication system. The multi-channel networking test device of the directional communication system is test equipment which is not limited by weather conditions, is safe in test, is low in cost and is real in networking capacity simulation. According to the technical scheme, a link state control module receives and analyzes link sate data input from the outside, sends conversion link attenuation control signals to a radio frequency exchange matrix, and sends multiple paths of radio frequency channel selection signals K into L radio frequency channel selectors respectively; the radio frequency channel selectors map radio frequency signals, needing link exchange, of L multi-channel direction communication devices to signal channels between N paths of radio frequency channel selectors and the radio frequency exchange matrix through M paths of radio frequency interfaces according to radio frequency channel selection signals sent by an interface of the link state control module; the radio frequency exchange matrix adjusts the attenuation amount of each communication link in real time according to link attenuation control signals provided by the link state control module. The multi-channel networking test device of the directional communication system is suitable for the networking test of the multi-device directional communication system.

Description

technical field [0001] The invention relates to the field of wireless communication system testing, a radio frequency switching network device used for wired testing of a multi-channel directional communication system, especially a radio frequency switching network used for multi-device networking testing of a multi-channel directional communication system in a laboratory environment device. Background technique [0002] Driven by the development of communication technology and application requirements, directional communication has been used more and more in civilian and military communication systems. Directional communication is different from omnidirectional communication, as long as the communication link can be established within the reachable distance of the communication equipment. Due to its directionality, directional communication, when applied to a network among multiple dynamic users, whether the directional beams between members can be aligned accurately, and ...
