Description

technical field

[0001] The invention relates to an environment monitoring system and method, in particular to a single-chip microcomputer-based wireless environment monitoring system and method. It belongs to the technical field of wireless monitoring. Background technique

[0002] At present, the wireless environmental monitoring system only has a simple data transmission function, that is, the slave machine collects environmental data, and the host machine receives the data wirelessly, which has a single function and is not widely used. With the widespread application of single-chip microcomputers and the increasing development of communication technology, ultra-long-distance real-time monitoring has attracted more and more attention, especially in national defense and industrial production. It plays an irreplaceable role.

[0003] In recent years, with the continuous improvement of industrial production efficiency and the continuous expansion of automation level and scop...

Examples

Embodiment 1

[0064] Theoretically speaking, 2.4GHz is a frequency band that works in the ISM frequency band. The ISM band is an industrial, scientific and medical frequency band. Generally speaking, countries all over the world have reserved some wireless frequency bands for industrial, scientific research, and microwave medical applications. The application of these frequency bands does not require a license, and only needs to comply with a certain transmission power (generally less than 1W), and do not Just cause interference to other frequency bands.

[0065] The regulations on ISM frequency bands in different countries are not uniform. And 2.4GHz is the common ISM frequency band of all countries. Therefore, wireless local area network (IEEE 802.11b / IEEE 802.11g), Bluetooth, ZigBee and other wireless networks can all work in the 2.4GHz frequency band; the so-called 2.4G wireless technology has a frequency band of 2.405GHz-2.485GHz (science, medicine, agriculture ), so it is called 2....
