Wireless transmission method and wireless transmission system

Abstract

The invention relates to a wireless transmission method and a wireless transmission system. The method comprises the following steps: establishing one layer of network topology by a stall detecting node and relay nodes; sending stall information which is collected by the stall detecting node to the relay nodes which are connected with the stall detecting node and are arranged on the same layer of network topology with the stall detecting node; establishing one layer or multiple layers of network topologies between the relay nodes or between the relay nodes and aggregation nodes; sending the stall information to a cloud processing platform through the relay nodes and the aggregation nodes which are connected with the relay nodes which receive the stall information or through the aggregation nodes which are connected with the relay nodes which receive the stall information. A multi-layer heterogeneous self-organizing wireless communication network architecture is set up to lower the congestion probability of channels and improve the data transmission speed. The chain performance and the anti-interference performance are improved through the self-adaptive channel coordination and allocation of the relay nodes. The stall detecting node is automatically connected with the relay nodes with great communication quality, and the packet loss rate is lowered. The efficiency of monitoring and managing the system is improved by the adoption of specific data frames.

Description

technical field [0001] The present invention relates to the communication field, in particular to a wireless transmission method and system. Background technique [0002] With the continuous development of the economy, the data and frequency of use of motor vehicles have also increased, and the management efficiency and safety of parking lots lag far behind social needs. [0003] According to relevant survey data, motorists have accounted for 12%-15% of road traffic flow in order to search for vacant parking spaces on the road. [0004] With the continuous development of intelligent buildings such as intelligent buildings and intelligent communities, the matching intelligent parking guidance system has emerged as the times require. The intelligent parking guidance system can save the time for drivers to find parking spaces and guide drivers to quickly drive into vacant parking spaces. However, the intelligent parking guidance system requires load wiring in the parking lot, ...

Problems solved by technology

[0007] In order to overcome the defect that the channel congestion of the wireless transmission network in the prior art cannot realize the real-time update of the status of the parking space, the main purpose of the present invention is to provide a wireless transmission method and system to solve the problems in the wireless transmission network existing in the prior art. The number of communication nodes (parking space detection nodes, relay nodes, convergence nodes, etc.) is too large, resulting in fierce competition for wireless channel resources, which in turn causes channel congestion problems, of which:
