Distributed environmental monitoring system based on wifi

Abstract

The invention relates to a distributed environment monitoring system based on WIFI (Wireless Fidelity) and belongs to the technical field of embedded wireless monitoring. The system comprises a wireless monitoring terminal. The system acquires parameters of the ambient environment by technologies of RS485 bus, analog / digital (A / D) conversion and the like, transmits data to a remote server by a WIFI technology with high transmission speed and strong anti-jamming ability and acquires the maximum energy of a solar battery panel by a maximum power point tracking technology to supply power for the system. The received data stream of extensive makeup language (XML) is analyzed by an environment monitoring center server, stored in a database and presented to an administrator clearly and quickly by a Java sever page (JSP), so that the administrator can control the change condition of the environment factor in real time. The system effectively solve the problems of wiring difficulty, high cost, short transmission distance and manual monitoring insufficiency in the environment monitoring process, obviously improves the operation efficiency of the system, facilitates maintenance of the system, and provides a stable high-efficiency operating platform for the environment monitoring work with widely distributed nodes and complex geographical environment.

Description

technical field [0001] The invention relates to a WIFI-based distributed environment monitoring system, which belongs to the technical field of embedded wireless monitoring. Background technique [0002] With the continuous advancement of science and technology in today's world, the environmental pollution problems it brings have become more and more prominent. Therefore, strengthening the monitoring and control of factors such as the temperature, humidity, light and ambient air pollution of the surrounding air has become an important issue. an increasingly pressing task today. Usually, the geographical environment of each environmental monitoring point is complex, the location is too scattered and unattended, so it is inconvenient to manually copy the data of each monitoring point, the execution efficiency is low, and the power supply is also difficult. The input cost of point data is too large, the wiring is complicated, it is difficult to maintain, and the transmission d...

Problems solved by technology

[0004] 1. The device adopts the RS485 bus cable to transmit data with the environmental monitoring center, which will cause the environmental monitoring points to be limited to areas with good geographical environment and easy wiring, and for environmental monitoring in areas with complex geographical environment and harsh conditions , the wired acquisition method usually has disadvantages such as excessive investment cost, complicated wiring, limited transmission distance and difficult maintenance, and it is impossible to flexibly change the node position

[0005] 2. The device adopts the power supply method of ordinary power supply circuit, which is neither environmentally friendly nor energy-saving and other factors are considered. It is unscientific and not recommended to conduct environmental monitoring in places with complex geographical conditions.

Adopting ordinary power supply not only increases the cost of power supply, but also increases the difficulty of power supply, and requires managers to replace batteries or maintain power supply lines on a regular basis
