An intelligent remote water meter based on MSP430 is designed to solve the problem of anti attack interference of smart card water meter which is widely used at present. The system consists of user water meter and water management center server. MSP430F169 microcontroller is used as the main chip. The main chip peripheral expands the serial communication, liquid crystal display and network communication. After collecting and processing the water flow signal, the information of water consumption is displayed by LCD, the serial port communication and GSM short message module are communicated, when the balance is insufficient, the water meter sends alarm short message and shuts off the water valve. The information exchange between user water meter and water management center is established through Internet. The management center can centrally manage user water meter through network, recharge value, inquire balance and so on, which provides convenience for user, and is the development direction of water meter in the future. It has high application value.
