Abstract

The invention discloses a wireless data transmission method and relates to the technical field of wireless data communication. The method comprises the steps of S1, establishing layer-by-layer transmitting wireless data communication links between a monitoring center and multilayer terminal nodes, wherein the monitoring center is in wireless connection with a first layer of terminal nodes, and each superior terminal node is in wireless connection with at least one subordinate remote terminal node; S2, setting a communication frequency of each terminal node; and S3, receiving data messages by each terminal node, and forwarding the data messages, wherein the uplink data messages are directly placed into uplink queues for waiting to be sent, after target terminal nodes of the downlink data messages are determined, the data messages are added to downlink queues for waiting to be sent. According to the method and the system, remote wireless data communication between the terminal nodes and the monitoring center can be realized, the communication interference can be reduced, and the stability of the communication links is ensured. The invention also discloses a wireless data transmission system.

Description

technical field [0001] The invention relates to the technical field of wireless data communication, in particular to a wireless data transmission method and system. Background technique [0002] The development of wireless communication technology has expanded the range of data exchange and transmission. Because the convenience of wireless data transmission technology has obvious advantages compared with the hard-to-install and high-cost wired data transmission method, the application of wireless data transmission technology is becoming more and more extensive. [0003] Invention patent application CN 104348523 A discloses a data transmission method of a wireless sensor node. When the wireless sensor node has data to transmit, it initiates a Bluetooth connection establishment process to establish a Bluetooth connection with a Bluetooth access point; the wireless sensor node and Uplink data transmission is performed between Bluetooth access points; Bluetooth access points tr...
