| Environmental safety of water resources is a major problem which country attachesgreat importance to, and the water quality detecting is one of the necessary technologyways of protecting environment in water resources. Water quality detecting instrumentis an important equipment for water quality detection. It is an automatic detectionsystem consists of online sample chemical pre-processing technology, automaticdetection technology, analyzing and processing of spectrum signal, and applicationsoftware technology. In allusion to the total design requirements of the multi-parameterwater quality detecting instrument，this paper carrys on the design of applicationsoftware and experiment research.The work has important practical application merit.On the base of researching and analyzing the basic structure and working principleof water quality detecting instrument based on micro spectrometer，and according to therequirements for system control,detecting flow, data processing and interface of usersoftware, this paper puts forward the application software design of the multi parameterwater quality detecting instrument, and achieved the debugging and testing experimentof the application software. The software system has the advantages of convenientoperation, friendly interface, high reliability, meeting the application requirements ofwater quality on-line detecting. The main research work includes the following content:①Studying of water quality detecting and chemical testing method and process,detecting of the multi parameter water detecting instrument based on the microspectrometer structure and its working principle, determined the overall plan of theapplication software design；②Researching the embedded hardware platform based on the Samsung S3C2410processor, this paper has transplanted the vivi boot code, customed the Linux2.6kerneland created the Cramfs root file system; designed the system device drivers, lay thefoundation of application software development and implementation;③According to the specific request of process control and test detecting of themulti parameter water detecting instrument based on the micro spectrometer, and withthe QTE development database， the multi parameter water quality detecting instrumentapplication software is designed in the Linux development environment. The softwarerealized the process control and test detecting in the parameter detecting process, dataprocessing and testing results preservation. ④Carrying on the online debugging of application software, including softwareplatform debugging, debugging drivers, and the test of accuracy and stability of waterquality detection, further improving the application software.⑤According to the comparable experiments are carried on with national standarddetecting methods in field.The contrast test results indicate the reliability of theinstrument application software. |
