Abstract

The invention relates to the technical field of security protection, and provides a 433MHz-based wireless ad hoc networking method. Networking is automatically achieved among a host and multiple equipment nodes to achieve data exchange and transmission; the equipment nodes broadcast and send join requests to the host to obtain connection tokens, are connected with the host through the connection tokens to generate link IDs and achieve two-way communication with the host through the link IDs, the frequency of corresponding channels can be set through a frequency hopping channel table, the host channel can automatically jump to the next channel when the host channel conflicts or does not receive information, and the equipment nodes can jump to the corresponding channels by scanning the channel of the host to achieve data receiving and transmitting on the same channel. Accordingly, the problems that existing 2.4G wireless transmission networking is complex and high in cost, and one-way one-channel 433MHz wireless data transmission is inconvenient to use and high in power consumption are solved.

Description

technical field

[0001] The invention relates to the technical field of data transmission, in particular to a method based on 433MHz wireless ad hoc network. Background technique

[0002] At present, smart home has developed by leaps and bounds in recent years. The main technologies currently on the market are ZigBee, Bluetooth, and WiFi. They are all based on 2.4G frequency transmission, and the transmission distance is short. WiFi is currently the most widely used technology in 2.4G wireless transmission. Compared with Bluetooth technology, it not only has a higher transmission speed, but also has a high transmission distance. In an open environment, it can transmit up to 200 rice. However, the biggest problem facing WiFi is low security, high power consumption, high cost of long-distance transmission, and complex networking, which makes it difficult to meet the requirements of buildings, communities, shopping malls and other places with high distance requirements. On the...
