| Abstract: | A meter collection and remote transmission system was developed with MSP430 as the core, which achieved real - time data collection, storage and remote transmission. It used the flash memory inside MSP430 to storage data and kept data from losing when the power is off. Farad capacitor worked as a reserved power supply to ensure the collection function of the meter to workwithin a certain period of time after the external power supply was cut down. TA6932 chip was used to driver 8 nixie tubes to alternately display the information of the water meter. Using RS -485 bus and network converter （ NETCOM - 10） converted the consumption data of water into TCP/IP protocol and uploaded to the local area network. |
