Abstract: This paper designed a kind of remote monitoring system combined with wireless and lineate networks. The wireless network was based on the global system for mobile (GSM) module to realize remote monitoring and the lineate network was based on the TCP/IP protocol stack, LWIP protocol to realize remote monitoring. The whole system was finished by the embedded chip STM32F103RBT6 constructed by Cortex-M3. The front end used the transducer to collect nature signals. After treatment, the signals were turned into voltage values and data values which were sent to the microprocessor. The microprocessor took the data as AT-named form and network frame form to send to the GSM module and network module respectively to realize remote monitoring, in the meantime the GSM module and network module could obtain the real-time information from the microprocessor to reduce the limitations of operation environment of equipment greatly.
Key words: combination of wireless and lineate networks; global system for mobile; LWIP protocol; remote monitoring
