Ad hoc wireless local area network and data sending and receiving method based on autonomous protocol and networking method

Abstract

The invention discloses an ad hoc wireless local area network with an independent protocol and a networking method and a data sending and receiving method. A wireless local area network with multi-level, multi-path network master-slave architecture, which includes a controller and a plurality of nodes; the controller stores a routing table for routing control; Control data in the protocol format to read the stored data in the final receiving data node, perform routing control on the sent control data through the routing table to obtain the stored data in the final receiving data node, and pass the routing table after the acquisition. The stored data in the receiving data node is fed back to the controller; the routing table includes the address of the final receiving data node, the address of each relay path node, the number of routes, and the priority level; between the controller and the node, and between nodes The following hardware chip protocol is used for data transmission.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a low-speed remote measurement and control ad hoc wireless local area network applied to the Internet of Things. Background technique [0002] In the application of the existing remote measurement and control system, 485, CAN, TCP / IP group wired network is often used, and ZIGBEE wireless networking is used. However, due to the limitation of 2.4G frequency and transmission power used by ZIGBEE, the diffraction ability and transmission The distance leads to unsatisfactory networking, and the 433MHZ can only form a point-to-point, point-to-multipoint star network and a multi-level relay single-path network. Contents of the invention [0003] In view of this, the present invention proposes a multi-level, multi-path network master-slave architecture wireless local area network with a network coverage of 5-15 kilometers, which is applied to low-speed remote measurement...
