基于GSM技术的多点温度巡回检测系统 摘 要 在农业生产和日常生活中，对温度的测量及In the industrial and agricultural production and daily life, the temperature measurement and control occupy a vital position. Multi-point temperature Tour detection system in all aspects of the application areas: electrical fire temperature of the non-destructive testing, electricity, telecommunications equipment overheating fault predict detection, air-conditioning systems, temperature test, different modes of transport of components overheating detection, protection Application and surveillance systems, medical consultation with the temperature-testing, chemicals, machinery and other equipment… overheated temperature detection. Temperature detection system applications are very broad. I design based on GSM technology tour of the multi-point temperature detection system for multi-point temperature detected a strong practical value. It can monitor real-time temperature, and determine whether the temperature alarm over temperature, if the temperature is too high you can GSM module to the control centre (such as GSM modules are connected PC or mobile phone terminals) a temperature alarm message. The system also can automatically detect sensor fault and informed the control centre via SMS to update the sensor. The alarm system from SCM controller, keyboard input, liquid crystal display, temperature sensor, serial communications, GSM module, the destination number, such as memory and power components. SCM controller used STC12C5410AD SCM is the core of the whole system, responsible for the temperature reading of the data processing, value keyboard input and output, through the serial port and the GSM communications and a series of procedures for action. SCM in the working parameters and functions set by the keyboard input circuit completed. LCD screen to display the parameters set at the data and tips, and other features. Called party numbers stored by the STC12C54AD MCU to complete its own EEPROM, brown-out after the set
