Embodiment Construction

[0029] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0030] refer to figure 1 and figure 2 , the preferred 433MHz wireless ad-hoc network method of the present invention, automatically constructs a network between the host, a plurality of relay stations and a plurality of device nodes for data exchange and transmission;

[0031] Host:

[0032] S1. Power-on initialization, configure the underlying driver and wireless module registers, so that the host is in the receiving state;

[0033] S2. Turn on the connection listening to obtain the connection information of the device node, that is, the device node will broadcast and send the join request and the connection request. When the join token of the device node matches the join token of the host, the host sends a message containing the connection token The response information of the device node is sent to the device node. When the connection token of...

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...
