Intelligent integrated control system for grain depot

The utility model relates to an intelligent integrated control system for a grain depot. The intelligent integrated control system comprises an upper computer that is connected with output terminals of a plurality of repeaters by a terminal receiver and a router successively. The repeaters are connected with out-cabin air humidity-temperature sensors, ventilation devices, LED screens and a plurality of optical fiber temperature-humidity sensor systems; and the input terminal of each optical fiber temperature-humidity sensor system is connected with an in-cabin air humidity-temperature sensor, a gas detector and a plurality of optical fiber temperature sensors. When the intelligent integrated control system is used, the optical fiber temperature-humidity sensor systems transmit information of grain temperature, air temperature and humidity, and gas information to upper-level equipment according to communication requirements; the upper computer carries out monitoring according to the received downstream data; and when an abnormal situation occurs, an alarm is sent out. On the basis of the design, the temperature measurement points are distributed widely; the positioning performance is high; grain temperature detection by electronic components can be eliminated; and the hydrogen phosphide corrosion-resistant performance is realized. Because of the wireless communication structure, grain situation can be monitored remotely; the monitoring effect and security are excellent; and the application range is wide.
