Wireless WIFI regulation and control system based on detection of pyroelectric temperature sensor

Abstract

The invention relates to a wireless WIFI regulation and control system based on detection of pyroelectric temperature sensor. The system comprises a granary, wherein a plurality of air pipes are arranged at the bottom of the granary, a plurality of branch pipes leading to the interior of the granary are arranged on the side wall of each air pipe, and the air pipes are respectively connected with a fan; a plurality of layers of vertically-arranged installing plates are arranged in the granary, and a plurality of pyroelectric sensors are fixedly connected to the lower surfaces of the installing plates; after the pyroelectric sensors on any installing plate are arranged in sets, the pyroelectric sensors are connected with a control unit, the control unit is connected with a local host through a WIFI transmission unit, and the WIFI transmission unit comprises an RF generator and an RF receiver; the local host controls the fan through the control unit. Changes of the temperature of grain can be monitored through thermistors, the local host can remotely monitor the changes of the temperature of the grain in the granary through the WIFI transmission unit, distance limitation caused by original cable transmission is avoided, and the control system has the advantages of being convenient to operate and reliable in control.

Description

technical field [0001] The invention relates to a granary, in particular to a granary maintenance system. Background technique [0002] Food is the foundation of human survival and development, and food security has always been a major overall strategic issue related to my country's national economic development, social harmony and stability, and national security and self-reliance. In particular, large state-owned granaries store a large amount of grain and require more grain depots. Then there will be problems such as wide distribution of grain depots and long communication distances, and the difficulty of unified management will also increase. To ensure the safe storage of grain is mainly to ensure that it is under normal temperature and humidity. [0003] The traditional method is to use testing equipment such as dry hygrometer, hair hygrometer, humidity test paper and thermometer to carry out manual inspection, and to ventilate, dehumidify and cool down the warehouses ...

Problems solved by technology

[0003] The traditional method is to use testing equipment such as dry hygrometer, hair hygrometer, humidity test paper and thermometer to carry out manual inspection, and to ventilate, dehumidify and cool down the warehouses that do not meet the temperature and humidity requirements. This manual testing method Time-consuming, labor-intensive, low-efficiency, and the temperature and humidity of the test have large errors and randomness
