| Abstract: |
| The power network voltage monitoring system based on GSM(Global System for Mobile communication) consists of several SMS(Short Message Service),based voltage monitoring instruments,GSM network,IBM - PC586 superordinate computer and statistical management software for voltage monitoring. Its hardware is introduced,such as circuits of voltage / current signal sampling,filtering,conditioning,A / D converter,display,clock,GSM- modem interface and so on,and its functions are described as well. The coding rules and steps of receiving / transmitting short messages through GSM and the further processing by voltage monitoring instrument are discussed. |
