Abstract:

To resolve the problem of insufficient heat supply and energy dissipation caused by cant monitoring the heat effect in the process of heat supply, the design and implementation methods of realtime monitoring far end interior temperature were proposed. Meanwhile, hardware design, software solution and working processing of temperature collection and communicator were discussed in detail. Atmegal16L microcontroller and CMX865 modem were embedded in telephone to collect far end temperature and control FSK(Frequency Shift Keying) to make telephone communication. Test results show that the system has the advantages of simple in structure, low power consumption and stable working. It effectively realizes the real-time monitoring of far end interior temperature.

Key words: heat supply, atmega-16L micro conrtrol unit(MCU), FSK communication
