Research And Application Of MSP430 Microcontroller On The Intelligence Water System

In order to adapt the reform of the nation system of water supply, studying and making use of the modern intelligence technique to realize the automatic supervision of the water supply, lightening the funds pressure because of"supply water first behind charge"of the department supplying water, reducing the trouble and dispute of copying the form and charging monthly ,using the modern science technique change the current administration structure of using water and water supply industry is imperative under the situation. The application of intelligent water meter not only improves work efficiency of the department supplying water and realizes using water electronically but also creates a condition for using water frugally and rationally.This thesis takes intelligent water-meter system based on IC card as the research object, and application and the development of the low power MSP430F413 microcontroller in the intelligence instrument is discussed detailedly. In this thesis, firstly, it puts forward a total design project of the intelligent water meter system which make use of the IC card technique; then it systematically introduces the composition, the characteristics and the functions of each part on the control system of this intelligent water meter which adopts low power MSP430F413 microcontroller as the core, designs the hardware electric circuit structure of the control system and studies the software to control the system. According to the combination of software and hardware, low power, anti_interferece and the security of the control system are studied and analyzed. In the end, the existing problems of the system and the improvement ideas of software and hardware in further contents and approaches are proposed.
