Environmental monitoring networking method and device based on combination of Zigbee module and 433M radio frequency module

Abstract

The invention relates to an environmental monitoring networking method and device based on the combination of a Zigbee module and a 433M radio frequency module. A network system consists of an end point, a plurality of sites and a plurality of sampling points, wherein the end point and the sites form a main link of a network topological graph; the end point is required to be provided with the 433M radio frequency module and a GPRS (general packet radio service) module, is a data gathering point, and is used for transmitting data to a remote server through a GPRS network; each site is required to be provided with the 433M radio frequency module and the Zigbee module if the site is designed to be provided with a Zigbee network, and is used for collecting the data acquired by surrounding nodes through the Zigbee module and sending the collected data to the subsequent site through the 433M radio frequency module; each sampling point is required to be provided with the Zigbee module and a sensor module, is a direct data source, and is used for sending the data to the corresponding site through the Zigbee module. According to the method, the range of an environmental monitoring network can be effectively expanded. The method and the device are applied to oceans, lakes and the like.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring and the Internet of Things, and relates to a method for automatically controlling a zigbee module, a 433M radio frequency module and a GPRS module to form a network by using a single-chip microcomputer, and transmitting the sampling data of each sensor to a designated server. Background technique [0002] Environmental online monitoring is one of the earliest fields to explore and practice the Internet of Things and vigorously promote it. Install various automatic monitoring instruments and meters and data acquisition and transmission devices at suitable points of point, line and area sources, and connect with the communication server of the environmental monitoring center through various communication channels to realize online real-time communication, so that the environmental status of the point perceived by the sensor It is continuously sent to the environmental protection dep...
