Biological pollution online monitoring system

Abstract

With the improvement of people’s living standards, the industrial system has begun to develop rapidly, and the problem of water pollution has also increased. Based on the above background, This paper designs an online monitoring system for biological pollution, this system can automatically or manually perform sufficient pretreatment of the water quality to be measured, it can graphically display the dissolved oxygen value and temperature data of the water quality in real time. The software part of this system uses the MK60N512VMD100 microcontroller of the Free scale Kinetis K60 series as the main control chip, and the IDE used is CodeWarrior for MCU 10.5. it based on the underlying components of the MCU, the software design of the MCU is completed. The upper computer uses Lab Window/CVI 9.0 of NI Company, which connects the equipment terminal to the Internet through SIM900A module, thus completing the communication between the upper computer and the equipment terminal. The hardware part of the biological pollution on-line monitoring system is designed to be portable. Its main purpose is to be convenient for users to carry and suitable for on-site and field operation. The system uses MCU-K60 as the control chip and realizes on-line monitoring on the hardware circuit platform. It is suitable for the determination of water dissolved oxygen and other parameters by departments such as tap water source monitoring, aquaculture farms, environmental protection, sewage treatment plants, beverage industry and scientific research units.
