Design of warehouse thermostat controller
Abstract: Today's computer-controlled technology applications, has temperature control system to achieve automation, intelligent, widely used in automatic temperature control circuit require fixed-point temperature measurement, such as refrigerators, air conditioners, greenhouse temperature control system, with the living standards are improving, the warehouse the thermostat controller has been widely used. The use of design C8051F MCU, its fast chips, the research and development of fast and quick features to achieve the purpose of the subject; transfer a single bus; This design uses LCD display to show the temperature using the LCD character liquid crystal display module is designed and manufactured for a dot matrix LCD display letters, numbers, symbols, etc.; DS18B20 to collect temperature data and set temperature interval for comparison, if the start cooling system is higher than the maximum set value and, if less than the minimum set value to start the heating system , in such a manner to maintain the thermostat of the warehouse; main module program using C language, C language, having advanced features , but also has the characteristics of the assembly language; and recorded every 15 minutes once the temperature data in the serial memory.
