Method, device, device and readable storage medium for wireless data communication

Abstract

The invention discloses a wireless data communication method, which comprises the following steps of: enabling a data processing node to receive a wireless data communication request sent by a data acquisition node and mark the data acquisition node as a node to be communicated; inquiring whether the wireless frequency band is in an idle state or not; and if so, performing wireless data communication with the to-be-communicated node by utilizing the wireless frequency band, sending wireless frequency band busy information to other data acquisition nodes in an online state, and forbidding the other data acquisition nodes in the online state to send wireless data communication requests to the data processing node. According to the invention, only a single node sends wireless data at the sametime, thereby avoiding the mutual interference between nodes, solving a problem of wireless frequency band resource preemption when a wireless sensor receives and transmits data, and improving the efficiency and accuracy of wireless data communication. The invention also provides a wireless data communication device, equipment and a readable storage medium, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of wireless data communication, in particular to a method, device, equipment and readable storage medium for wireless data communication. Background technique [0002] Existing wireless communication devices will preferentially use a group of nodes to directly transmit and receive data to transmit data while ignoring mutual interference when other nodes simultaneously transmit and receive data, and use multiple retransmission strategies to improve the success rate of data transmission. This method is characterized by: [0003] (1) There is no need to consider the influence of other nodes, and the design is simpler; [0004] (2) When there is only one group of nodes sending and receiving data at the same time, there is no need to go through the process of networking to allocate wireless frequency band resources, which is more efficient. [0005] However, its disadvantage is that the anti-interference abilit...

Problems solved by technology

[0005] However, its disadvantage is that the anti-interference ability of wireless data communication is poor. In order to reduce the interference of other nodes, the communication data length needs to be as small as possible to shorten the transmission time, thereby reducing the probability of data confusion, resulting in the communication data length being limited in this communication mode. Moreover, when multiple nodes send wireless data at the same time, the wireless data in the same frequency band will interfere with each other, and a data retransmission strategy is required to improve the success rate, thereby reducing the efficiency of wireless data communication
