Design Of Embedded System Mechanical Arm Motion Multi-parameter Detector For Water Quality

Water quality monitoring is to protect the water environment of the importance of safety techniques, and existing environmental water quality monitoring system has a long test cycle, test parameters of single and low efficiency of work, not been able to reflect the current status of water environment, can not meet the modern water environmental monitoring and protection requirements. Therefore, the development can be detected on the multi-parameter water quality sampling and automated analysis, automatic water quality monitoring system is particularly urgent.For water quality monitoring of existing environmental problems in the system, a mechanical arm motion detector multi-parameter water quality technology solutions, according to detection robot arm motion control requirements and the requirements of the multi-parameter water quality testing system works, multi-parameter water quality analysis of the practical application of work flow detection system, the main hardware of embedded system proposed programs and Linux-based multi-parameter water quality monitoring system apparatus of the overall scheme of embedded software systems; Used as the main processor S3C2440A, completed the top embedded hardware systems; Linux-based system built multi-parameter water quality testing instruments embedded software platforms, and migrate bootloader, kernel and root file system and GUI platform Qtopia, the preparation of the relevant drivers; Designed and developed a system based on Qtopia graphical user interface and control tests improve detection, simple operation, intuitive, flexible user application software; Completed a prototype embedded system debugging and application of some experimental results show that the system reaches the initial design requirements. This thesis are as follows:①Issues raised in the multi-parameter mechanical arm motion detector water quality requirements under the overall technology program to determine the multi-parameter water detector the overall structure of the embedded system programs;②According to the general program requirements of embedded system designed to S3C244A embedded hardware circuits as the core system, set up the hardware technology platform;③According to the process of multi-parameter water quality monitoring instrument, motion control of robot movements required in the embedded hardware platform, built on Linux operating system software platform, and migrate bootloader, kernel and root file system and GUI platform Qtopia, designed a multi-parameter water quality testing instrument user application software systems;④Completed a prototype application debugging and some experimental results showed that multiple instruments can basically meet the water quality parameters of detection.
