Water quality monitoring adds sharp tools unmanned ships to make up for the shortcomings of traditional monitoring

Jiangnan Water Town in March has red flowers and green willows, and the water is clear and level. In a wide river in Suzhou high tech Development Zone, there are three boats with a length of more than one meter. On the shore, the staff of the monitoring station hold a remote control and control the unmanned ship to sample orderly at different points. The notebook computer continuously receives the group data of water quality monitoring, and quickly forms charts and pictures. The inspector said happily, "with the unmanned ship, the efficiency of water environment monitoring is much higher, and the labor intensity is much lower!"

since the importance of environmental protection has been recognized and accepted by the public, relevant departments have also invested more and more in environmental protection. As a "pacesetter", the field of environmental monitoring has welcomed a new member. In order to realize the optimal allocation of resources, in recent years, the use of unmanned monitoring equipment has become one of the mainstream trends. Both UAVs and unmanned ships have made great achievements in their respective fields

at present, the surface water environmental quality monitoring is mainly to understand the water quality of river and lake sections through manual sampling or relying on the automatic monitoring mode. In order to solve the problems that a section or a river or lake cannot be continuously monitored for a long time, and the timeliness of data is not guaranteed, the emergence of unmanned ship technology of Beijing ruishengte Technology Co., Ltd. provides a new solution for traditional water quality monitoring

unmanned ships make up for the shortcomings of traditional monitoring

traditional water quality monitoring requires staff to actually go to the monitoring water area for sampling, but the water area structure is often complex and staff are inconvenient to take samples on the spot, resulting in many difficulties in monitoring and sampling; It also serves the environmental monitoring center station. The unmanned ship has obvious advantages. It has the characteristics of convenient sampling, rapid handling of emergencies, point sampling in diverse water environment, real-time data transmission and feedback, etc. The person in charge of Beijing ruishengte Technology Co., Ltd., the research and development unit of environmental monitoring unmanned ship technology, said

each unmanned ship is equipped with a GPS system, and the control mode is also divided into manual remote control and satellite GPS control. The manual remote control can complete the water area monitoring within 2km between the man and the ship, and the GPS control can realize the unmanned driving under the continuous status of the network signal. At the same time, download the predetermined target map before the inspection, and plan the path points on the map to avoid the detection error caused by the position deviation. The quality of the unmanned ship, the sampling and testing methods of the mold micro machining technology and the use of data have been certified by the environmental protection department. The methods are compliant and the data are reliable

is the application of unmanned ship helpful to the monitoring of section water quality? The staff answered that the unmanned ship can monitor and analyze the water quality at the junction of the section, judge the diffusion trend of pollutants and the causes of water quality according to the flow direction, sample accurately and check easily, so as to reduce the evasion caused by the unclear causes of the junction of the section

the current situation of water quality monitoring is based on the fixed monitoring points. In the inaccessible waters, the unmanned ship technology can be used to realize water quality monitoring. In fact, it is a supplement to the conventional monitoring and sampling methods

in terms of data collection and transmission, the unmanned ship is equipped with a 360 ° rotating camera to capture the image of the monitoring scene. The data collected by the unmanned ship is directly transmitted to the user server to establish a data platform. The rendering diagram is made based on the pollutant concentration, and the corresponding data form a trend analysis diagram. Various styles of data display graphics are convenient for users to view and analyze. Ruisheng has a unique "one drop of water" detection technology, that is, only one milliliter of water is needed for sampling, and the detection results can be obtained in three minutes. Several detection items can be carried out at the same time

multi type unmanned ships solve monitoring problems

rising technology has three fully automatic unmanned monitoring ships with different functional positioning, namely c100s fully automatic unmanned sampling/monitoring ship C180 automatic unmanned water quality monitoring ship and c100p automatic unmanned mapping ship. The three full-automatic unmanned monitoring ships have the ability of independent patrol survey or group monitoring. They all have the ability to record the water quality parameters, meteorological parameters and other data of the access points during the monitoring period in real time, and have the ability to capture the whole process video information and 360 ° picture information of a certain location

the functions of the three ships are biased. C100s can be applied to the water quality parameters of blue-green algae. It has been applied in the water quality monitoring project of Taihu Lake. The analysis of water quality changes plays an early warning role in the monitoring of blue-green algae; C180 can monitor the source nitrogen, phosphorus and other indicators of urban black and odorous water problems, and conduct continuous and fixed-point on-site analysis on the water area to be investigated or polluted; C100p is an unmanned side scan sonar ship. It can detect underground pipes through the images returned from geomorphic sonar scanning, and preliminarily analyze the conditions of underwater river channels and large-scale underground channels. This is also a new highlight of the application of unmanned ship technology in water quality monitoring

the information obtained by the unmanned ship finally enters the customized software platform through network or manual import for data analysis and statistics, and forms graphic data such as pollution data distribution map and curve chart for environmental management

the core technology is the data analysis system

it is understood that the unmanned ship monitoring system integrates five technical systems, namely, the unmanned ship navigation system, the monitoring and analysis system, the data cloud platform system, the water quality rendering system and the big data environment data analysis system

the vessel can navigate and navigate autonomously, set the navigation route in advance, and realize automatic return according to GPS positioning; Ultrasonic automatic obstacle avoidance; It can be equipped with sampling and monitoring equipment for sampling or data and detection

continuous flow analysis method is adopted for rapid and accurate analysis; Complete sample handling; It can realize simultaneous analysis of multiple project channels

data is shared with cloud real-time transmission; Simultaneous uploading or downloading of multi-point data; Implement the parameter correction of the equipment through the cloud; Realize the storage and backup function of a large amount of data; Review the working duration and navigation track of the unmanned ship; With the help of various geographic information software, the pollutant distribution graph is calculated and generated

according to the data of the detection system, automatically generate a variety of performance graphics of water pollution, including pie chart, line chart, histogram, GIS map, etc

according to the water temperature information, meteorological information and environmental pollutant detection data of the river water body, including the five conventional parameters of water quality: algae, ammonia nitrogen, COD, total phosphorus, total nitrogen, etc., and in combination with the discharge of surrounding industrial enterprises and urban domestic sewage, establish an appropriate overall size of the host: 830 × five hundred and eighty × 2150mm; A quantitative model for comprehensive diagnosis and assessment of water pollution in river basins. Quantitatively clarify the causal relationship between emission control and specific categories of water environment through the time and space correlation of each indicator, predict and predict the occurrence of environmental pollution accidents, and calculate the total amount of each pollutant source

this data analysis system is leading and unique in China at this stage, which can ensure the timeliness, reliability and efficiency of data processing

the advantages of unmanned ships are becoming more and more obvious

advantage 1: improve the monitoring efficiency

break the situation of sparse density and regular monitoring of traditional automatic monitoring stations. After the application of unmanned ships, 3 points can be set per kilometer, an increase of 10 times the monitoring points, and the density is enhanced. The unmanned ships with batteries can sail continuously for 6-8 hours to achieve continuous and real-time monitoring data

advantage 2: reduce work intensity

the fully automated processing of unmanned ships can reduce the work intensity of monitoring personnel and liberate monitoring personnel from strong labor

advantage 3: reduce the risk coefficient

traditional monitoring requires sending personnel to complex water areas for on-site monitoring and sampling. There are risk factors in the work. After the unmanned ship is applied, it only needs to remotely operate the unmanned ship to enter complex water areas for sampling and monitoring

advantage 4: reduce investment

at this stage, water quality monitoring is still dominated by automatic monitoring stations, and many places are still under construction. However, the number of automatic water quality monitoring stations is far from meeting the water quality monitoring needs, with a year-on-year increase of 0.65%. The investment in the construction of the stations is huge, and the operation and maintenance costs are high. An unmanned ship can replace dozens of automatic stations, reducing the cost by at least two-thirds, and the monitoring density is high, It has become a new method to replace the automatic water quality monitoring station

the application advantages of unmanned ships in the field of environmental protection are far from human beings. It can not only greatly shorten the working time and improve the work efficiency, but also solve a lot of resources. With the development of technology and the change of people's environmental protection concept, unmanned technology must be one of the main trends in the future. At the present stage, most users of rising tech mainly purchase services, providing high-quality solutions for water quality monitoring departments, which have been applied in the Yangtze River section, Wujiang water area and Baiyangdian Lake. The market demand for this new detection method is huge, and the application scenarios in the future will be more extensive
