Design Of Measuring And Controlling Software For Electrical Conductivity Detector

The conductivity detector is a device used to measure the conductivity of liquid,which is widely used in all kinds of fields,such as food safety,environmental monitoring,chemical analysis and industrial process control.The measurement and control software serves as the main controller in the conductivity detector’s normal operations,and it plays a crucial role.The functionality and performance of the conductivity detector are directly impacted by the quality of the measurement and control software.As such,the study of high-quality measurement and control software for the conductivity detector holds significant application value.Through the in-depth investigation of the development status of conductivity detector and its measurement and control software technology at home and abroad,a measurement and control software of conductivity detector with automatic control function and remote monitoring is designed.The software can realize the range adaptive switching function and can automatically complete the measurement,calculation and recording,which improves the accuracy and efficiency of measurement.The measurement and control software comprises both upper and lower computer software components.Using modular design principles and a three-layer architecture,the overall framework of the measurement and control software is developed by combining the functional interface reserved for the hardware platform of the conductivity detector with the functional requirements of the measurement and control software.Keil is selected as the lower computer software development platform,and Qt based on C++ and cross-platform development is selected as the upper computer software development platform to complete software development.A complete communication protocol is developed to realize the scalability,maintainability and reusability of the measurement and control software.Using narrowband Io T modules to achieve remote monitoring of equipment;the temperature control fuzzy PID algorithm is used to realize the real-time control of temperature.The range adaptive switching method is designed to realize the dynamic control and debounce of the range when detecting the conductivity.The upper computer software interface is designed by combining the Qt Disigner interface editor design with the manual writing interface code.Using touch function to realize the interaction between user and interface;SG filtering algorithm is used to smooth the conductivity and filter out noise.Flash memory is used to store and query the information related to conductivity detection.Manage user information and Flash storage information through database technology;using multithreading technology to improve the response speed of the software;using the V-model testing approach,the software’s individual units and the conductivity detector measurement and control software system were tested,which confirmed the overall correctness and stability of the measurement and control software.It was confirmed that the expected objectives were achieved,and the software operated smoothly while meeting the design requirements.
