The invention discloses an FPGA based intelligent granary
monitoring system which comprises a ZigBee networking communication module, a solar panel, a
power supply voltage stabilizing module, an FPGA controller, a wifi module, a PC terminal, an
air temperature and
humidity sensor, a grain stack temperature and
humidity transmitter, a smog sensor, a CO2 concentration sensor, a
combustible gas sensor, an
infrared pyroelectric sensor and a
flame sensor. Output of the solar panel is connected with input of the
power supply voltage stabilizing module; the output end of the
power supply voltage stabilizing module is connected with the power supply input end of an FPGA controller; the FPGA controller is connected with a ZigBee coordinator and the wifi module; the wifi module is connected the PC terminal; and the output end of an FPGA is successively connected with an exhaust fan device, a
liquid crystal electronic screen, an axial flow blower fan, an alarm module, a voice module and a monitoring module. Thus, a granary manager can accurately and timely obtain granary information and makes automatic adjustment needless of reaching the site, the monitoring safety is high, the accuracy is high, and the application range is wide.
