Test system for information acquisition wireless downlink channel network

Abstract

The invention discloses a test system for an information acquisition wireless downlink channel network, which comprises a host machine, a concentrator shielding box connected with the host machine, and a plurality of assemblies which include a variable attenuator, a combining network module connected with a radio frequency cable of the variable attenuator, a collector shielding box connected to the radio frequency cable of the combining network module, wherein the assemblies and a route build the hierarchy and the route matched with a wireless network according to the hierarchy of the wireless to be tested, the variable attenuator of the assembly in the first network hierarchy is connected with the concentrator shielding box through the radio frequency cable; the variable attenuator of the assembly below the second network hierarchy is connected to the combining network module of the former hierarchy of the assembly through the radio frequency cable; a connection serial port is arranged the host and the concentrator shielding box; and the host can control the transmission distance of the signals in a radio frequency cable channel in the multi-wireless network hierarchy and route by adjusting attenuation amplitude of the variable attenuator, further adjusting the wireless hierarchy and the route.

Description

technical field [0001] The invention relates to the technical field of network testing, in particular to an information collection wireless downlink channel network testing system. Background technique [0002] At present, the wireless downlink channel network for information collection of the State Grid mostly uses a wireless ad hoc network to realize communication network functions such as aggregation, transmission, and interaction of low-voltage power users' electricity consumption information. [0003] The wireless self-organizing network includes two kinds of communication equipment, the full-function central equipment module installed in the concentrator and the simplified function sub-station equipment module installed in the electric meter and collector. The central equipment module of the concentrator can communicate with the sub-station equipment modules; the sub-station equipment modules can forward data. The wireless self-organizing network can be composed of a ...
