Design Of Portable Remote Control Ship And Its Application In Wetland Monitoring

Wetland ecosystem is one of the important components of the national ecological security system,and it is also the basis for maintaining the natural water cycle and ensuring the sustainable development of economy and society.However,the current wetland environment has become worse,part of them is degradating,wetland conservation is of great urgency which is the premise of all wetland protection work,therefore,it’s particularly important to monitor the wetland environment,early monitoring relies on manual work which is time-consuming and laborious,with the development of techonology,the researchers use satellite remote sensing technology to monitor macro changes of wetland environment,such as GIS,but when face the cloudy and rain,it can’t monitor accurately.In order to solve the problems existing in the current wetland monitoring methods,this study combined single chip microcomputer technology,C# software programming and sensor technology to design a portable remote control ship suitable for wetland environmental monitoring.The main research results are as follows:(1)By writing the upper computer software in C# to control the 51 microcontroller equipped with n RF905 chip.The chip was designed to generate pulse-width modulation pulse signal to adjust the steering gear rotation Angle and motor speed,so as to realize the adjustment of ship speed and course;(2)The sampling function was realized through the upper computer software to adjust the change of I/O high and low level of 51 single chip microcomputer equipped with n RF905 chip to control the pull of the optocoupler relay,so as to control the function of the submersible pump and realize the water sample collection.(3)The realization of water quality index monitoring function was to send AT instruction to HC-12 microcontroller through the upper computer software,with the purpose of controlling the HC-12 microcontroller connected to the water quality index sensor for corresponding action adjustment and data return.This paper gave a detailed design scheme and equipment selection for the software and hardware of the ship.The software part included: software programming of the ship speed and heading,water sample collection,software programming of ship positioning and water quality index monitoring.The hardware part included ship speed heading motor and drive plate,steering gear,water quality indicator and ship positioning sensor.Finally,i made the ship and programmed the software,and verified the software and hardware functions and adjusted the code.In the portable remote control ship system test part,the ship successfully collected the water sample by remote control and read water quality index measurement data.The accuracy of data under different control distance was also verified.
