Urban information collection system based on wireless information transmission and energy simultaneous transmission network

Abstract

The invention discloses an urban information collection system based on a wireless information transmission and energy simultaneous transmission network, and belongs to the technical field of wirelessinformation transmission and energy simultaneous transmission networks. The system comprises a wireless energy transfer module. The wireless energy transmission module is in electrical output connection with a wireless transmission module for remote transmission. The wireless transmission module is in electrical input connection with an information transmission module for transmitting information. The single-chip microcomputer is in electrical output connection with a power supply module used for providing a power supply, a display module used for displaying information and a classification statistics module used for classification. In the system, the wireless energy transmission module provides electric energy for the power supply module. Therefore, when the information source or the external access point transmits the information to the relay, the energy can also be transmitted to the relay, so that the relay obtains redundant energy budget for cooperative transmission, the energy of the relay does not need to be consumed, a battery does not need to be replaced, and the service life of equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of wireless information transmission and energy simultaneous transmission network, in particular to a city information collection system based on wireless information transmission and energy simultaneous transmission network. Background technique [0002] In a wireless network, due to scattered urban areas, climate or geographical reasons, nodes may be far away from each other or may be obstructed by each other, which makes LOS communication unfeasible, and idle nodes between two nodes are used for relaying, so, Even if there is a direct link between the source and the target to improve system-level performance, it is still useful to use intermediate idle nodes, so that the relay node can listen to the information transmission of the transmitting source and resend it to the destination after modification, To assist the whole decoding process, in case the relay operates in battery-assisted mode, it is not ver...

[0002] In a wireless network, due to scattered urban areas, climate or geographical reasons, nodes may be far away from each other or may be obstructed by each other, which makes LOS communication unfeasible, and idle nodes between two nodes are used for relaying, so, Even if there is a direct link between the source and the target to improve system-level performance, it is still useful to use intermediate idle nodes, so that the relay node can listen to the information transmission of the transmitting source and resend it to the destination after modification, To assist the whole decoding process, in case the relay operates in battery-assisted mode, it is not very beneficial for the relay to participate in this cooperative transmission, because it has to expend its own energy, limited by the relay device battery Due to capacity constraints, its working time is also limited, and because it is sometimes difficult to replace the battery, the service life of the wireless network is limited. For this reason, we propose a network based on wireless information transmission and energy simultaneous transmission network city information collection system
