Abstract

In order to improve the intellegence of the solar hot water system, we design the communication module of solar hot water system based on GSM short message. The communication module is composed of embedded dual serialport MCU, GSM module and level conversion circuit. The paper introduces the hardware structure of the communication module and the serial communication protocol between single chip and control instrument, then analyzes the working process of the communication module. The combination of the GSM short message technology and solar hot water system enhances the intelligent level of solar hot water system.
