Embodiment Construction

[0020] like figure 1 As shown, an environmental monitoring system connected to an IPv6 network, the local environmental monitoring system adopts the ESP8266 module star topology network, and the software programming of the ESP8266 at the central node allows multiple TCP / IP communication ports to be connected by nested processes. , to receive data from multiple modules, and the central node sends the data to the gateway through the serial port. The gateway takes cheap and low-end embedded devices as the core, and runs a lightweight protocol stack inside, which only occupies dozens of KB. The basic TCP / IP protocol can be run with the memory overhead of the gateway. The gateway starts to try to obtain the IP address by periodically executing the dynamic host setting protocol, the multicast listening protocol and other protocols, and connects the serial data to the Internet through the Ethernet interface to complete the data transmission to the remote. end data center. The enviro...

Abstract

The invention discloses an accessible IPv6 network. The invention relates to an environment monitoring system supporting automatic acquisition of an IPv6 address and compatible with an IPv4 network, and discloses an implementation method of the environment monitoring system which is based on low-cost embedded equipment, is suitable for an IPv6 and IPv4 dual-stack network and supports automatic acquisition of an IPv6 / IPv4 address. The method mainly comprises the following steps: 1, preparing raw materials; the ESP8266 collects and displays the air quality data of each point of the local end; the ESP8266 is locally networked and sends serial port data to the gateway; a gateway taking low-end embedded equipment as a core runs an LWIP2.1. 1 protocol stack in a program; the embedded device processes serial port data and then transmits the data through TCP / IP communication in a program, the data are collected once every 300ms, the IPv6 network is used for accurately and effectively transmitting the data in real time, the indoor air quality in a target area can still be observed at a far end, and remote analysis and control are achieved.

Description

technical field [0001] The invention realizes an environment monitoring system that can be connected to an IPv6 network, in particular to a method for an indoor environment monitoring system to access the IPv6 network. The method uses a low-end embedded device as a gateway that can access the IPv6 network, and The gateway runs a lightweight TCP / IP protocol stack and supports automatic acquisition of IPv6 addresses. This is an embedded gateway that converts serial data to Ethernet data and supports IPv6 network environment. The monitoring system is remote, lightweight, real-time and safe, and belongs to the technical field of embedded computer networks. Background technique [0002] The serial communication bus is a local communication technology that sends data in the form of a continuous serial data stream. The serial port sends and receives bytes bit by bit. The IPv6 network is designed to replace the IPv4 network. In the environment detection system, the data is aggregat...
