Problems solved by technology
Since the local node in this system does not know the length of the data sent by the peer node, it will cause the transmission node to switch to the sending state because it is ahead of or lagging behind the actual receiving time slot, resulting in a conflict or waiting for a The longest data frame takes a long time, reducing system efficiency

Embodiment Construction
[0059] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0060] Such as figure 1 As shown, according to the first embodiment of the present invention, a wireless network-based inter-node out-of-synchronization processing method is provided, which is applied to the out-of-synchronization processing process after the local end node completes sending valid data to the opposite end node, including :
[0061] S101. The local end node respectively acquires the received signal strengths when and after the valid data transmission is completed, and obtains a difference between the two signal strengths.
[0062] The acquisition of the signal strength difference by the local end node is further described as, based on the wireless network, the local end node obtains the number of sampling points according...

The invention provides a method, a device and a system based on a wireless network for processing inter-node step out, and the method, the device and the system based on the wireless network for processing the inter-mode step out are applied in a step out process after a local tip node completes effective data sending to a corresponding tip node. The method includes the steps of respectively obtaining through the local tip node intensity of a received signal when the effective data sending is completed and intensity of a received signal after the effective data sending is completed, and obtaining a signal intensity difference value of the intensity of the received signal when the effective data sending is completed and the intensity of the received signal after the effective data sending is completed; determining whether the corresponding tip node is in a data sending state or not according to the comparison between the signal intensity difference value and a preset threshold value; keeping the local tip node in the data receiving state and analyzing received data which are sent by the corresponding tip node when the corresponding tip node is judged to be in the data receiving state, and turning the local tip node to be in the data sending state and sending effective data when the corresponding tip node is judged not to be in the data receiving state. A phenomenon of low system efficiency caused by long-time waiting or inter-node sending conflicts is avoided, and working efficiency of the system is improved.
Description
technical field [0001] The invention relates to the field of communication transmission, in particular to a wireless network-based out-of-synchronization processing method, device and system between nodes. Background technique [0002] With the continuous advancement of communication technology, wireless communication provides people with convenient and fast network communication services, and the corresponding data services have also developed rapidly. The synchronization method of the existing wireless communication system is realized based on the global positioning system. Each node in the system performs receipt sending and receiving operations according to the clock in the entire network. If the nodes cannot be synchronized, the uplink and downlink signals cannot be sent and received at the same time, which will lead to signal interference between the nodes, and the consequent consequence is that various services cannot be carried out normally. [0003] In a synchrono...
