The mobile environmental monitoring system is aimed at increasing the processing speed of measurement analyzes and increasing the scale of the study. The algorithm of analysis and modeling of extreme floods includes: construction of a series of hydrographic maps of the largest floods and graphs of characteristic water levels, assessment of the peculiarities of floods, formation of a database on channel morphometry and the state of flood objects. An important role is given to the assessment and forecast of the state of the Dniester and anthropogenic impacts on it in connection with such indicators as morbidity and control of pollution caused by flooding. Man-caused ecological safety of use of hydro resources and hydroecosystems in general should be based on the hydroecosystem concept of balanced nature use. GIS technologies (ArcView GIS 3.2a) were used to directly implement the tasks of estimating the time of penetration of pollutants into groundwater. The evaluation of the protective properties of the rocks of the aeration zone was performed by creating a spatial model to determine the relationship between objects using the module Georgesessig ArcGIS. Survey materials allow you to create 3D terrain models with an accuracy of 15–20 cm and aerial mosaics at a scale of 1: 1,000 – 1: 5,000.

A wireless measurement and control system for vegetable greenhouse is developed for the sake of overcoming the shortcoming of the wired measurement and control system such as complex wiring and low anti-interference capacity. In this environmental monitoring system, including the hardware design, software design and energy control strategy design, then we describe a comprehensive system testing process. In the hardware system testing, testing data verified the monitoring node performance. At last simulation data shows that the improved multi-hop network transmission protocol has obvious advantages.

This research aims to develop an automatic unmanned aerial vehicle (UAV)-based indoor environmental monitoring system for the acquisition of data at a very fine scale to detect rapid changes in environmental features of plants growing in greenhouses. Due to the complexity of the proposed research, in this paper we proposed an off-board distributed control system based on visual input for a micro aerial vehicle (MAV) able to hover, navigate, and fly to a desired target location without considerably affecting the effective flight time. Based on the experimental results, the MAV was able to land on the desired location within a radius of about 10 cm from the center point of the landing pad, with a reduction in the effective flight time of about 28%.

In order to protect the components of monitoring, some measures should be taken when refuge chamber uses outside environmental monitoring system. This paper designs a kind of protective device for outside environmental monitoring system based on related theory analysis and coal mine environment. It can protect monitoring components from gas explosion shock wave. Meantime there is good contact between sensitive element and outside environment to guarantee the normal work of the monitoring system. Finally, this paper builds the model of protective device, and analyses its structural strength.
